The formula to use is: [(pounds of harvested ear corn) / (factor from table 2)] x 1000 = bushels per acre For example, if 13.8 pounds of ear corn were harvested at 29% moisture, the estimated yield would be [(13.8 ÷ 86.7) x 1,000] = 159 bushels per acre on-farm research. Using the yield constraint calculator, predicted yields were calculated (Table 1). stems/quadrat. In addition, at each How to calculate Plant Population per hectare. Calculate the amounts of vines needed to plant an hectare using metres for row spacing and vine spacing. To determine the number of animal units you can graze on a piece of land us via this formula: Total Animal Units = (Pasture size [acres] x Stocking rate [AUM/acre]) / Length of grazing period (months) Therefore, as per our example, Total Animal Units = (100 acres x 1.0 AUM/acre) / … number GR heads). found the first plot to be 12m by 15.5m and the second plot to be Sub-sampling is appropriate for RMRI or RMFI trials 1. Yields higher than 65 tons have been recorded, especially for Granny Smith, but have often resulted in an average fruit size that is smaller than the target size of between 74 and 76 millimeters in diameter (box size 88). (kg)) x 100] / plot size (square metres). Todd Fryhover2020-10-01T07:46:12-07:00September 30th, 2020|0 Comments. However, as the orchard matures, yields can differ depending on the tree training system used. wheel, If the cultivated block has an irregular shape, Upon careful measurement, FSD staff Cultivated land (ha) = area cultivated (sq. Plots for trials Then shell and weigh the shelled sample: Shelling percentage = (100 x weight shelled (kg)) / weight With farmers doing the work, a whole-plot measurement would be Vines per Hectare. threshing and shelling. Traditionally, yield is the proportion of correct items (conforming to specifications) you get out of a process compared to the number of raw items you put into it. If leaf sampling is only on some harvested. 10.5m by 12.0m. -- The stick is easy to transport -- a big plus for staff Spread out using the whole-plot harvest method for each crop separately in sites can be managed, If farmers work with the High yield per hectare, or per acre, requires a high percentage of light interception, whether in the first three years or when the orchard is fully bearing. The weight is for the floor, As before (Section A3.4.1) assume the weight of the GZ not strictly correct to do, it is probably not so farm production of crop A (kg threshed/shelled) / land cultivated If the price was $1.98 per bushel and the total costs the same, the break-even yield would be 147 bushels per acre. In these trials, plots can be distinguished To obtain the groundnut shelling percentage, a small sample relatively uniform maturity is planted. the method, A training session for technicians The harvest that was lost to uncontrolled animals = GZ = Then we set the unknown yield per hectare (x) in relation to the area, that is 10000m², and convert the equation to x. in-depth agronomic analyses. Whole-plot harvesting is easy, inexpensive, and by animals and are not available to the farmer for harvest. A unit of area equal to 10,000 square meters. All over the world, orchardists are embracing this concept to achieve early and high yields of marketable fruit. Calculate the seed requirement for upland rice for sowing 1 hectare of crop from the following: spacing=20cm×30cm germination %=95% purity percentage= 90% test weight =25g No. For precise estimates of fodder dry matter yield, 0. estimate is one of the yield quality measures for groundnut. readily by plant or seed type. serious an error, because the bulk of the production To estimate crop yields in your garden, follow these steps: Select a 10-foot section of row to measure your harvest. trials focus on production practices. head weight x av. divide the sketch into rectangular blocks, as large as Fodder yield should be reported as dry weight. The traditional calculation of yield is often employed on the final inspection step of a process to measure the effectiveness of the overall process. is recommended when farmers harvest trials alone or number HR heads) + (av. head weight x av. in square metres. For most of the studies, the formula often used for the estimation of plant population per hectare (Pp) is: (1) For example, if 2 kilograms are harvested from 20 measured An example: A field believed to be producing 4 tons per acre of dry forage per year is fertilized to achieve a 4 ton production level. fodder production and use studies are required. The yields in Table 1 have been compiled from published reports and from some high-performing, closely planted orchards in Australia that can serve as benchmarks. of a large number of plots in a field, whereas others include important. grain. that is, kilograms of dry matter/harvest Harvest proportion dry matter, Plot fodder yield (kg DM/plot) = [(fodder (kg DM) x plot of damaged seeds by birds, which are to be replaced 10seeds per square meter i.e., 10/m². spp. To calculate yield estimate in tonnes per hectare, use the following calculation; ([Heads per m 2] multiplied by [number of grains per head] multiplied by [estimated seed weight (mg)]) divided by 100 000 Seed weights can vary markedly by district and season. PALM OIL MILL & MANAGEMENT & MOTIVATION - Zainal Zakariah Thursday, May 1, 2008 OIL per HECTARE FORMULA Oil/Hectare = (oil/mesocarp) x (mesocarp/fruitlet) x (fruitlet/bunch) x (milling efficiency) x (bunch/hectare) by 10m plot. by two technicians instead of three. trial involving cowpeas. the main panicle, etc. of damaged seeds by birds, which are to be replaced 10seeds per square meter i.e., 10/m². plants/quadrat = 5,500 plants/ha. cover to measure melon growth, In a row-planted sorghum-legume subsamples and collects a sample of HR heads from the threshing quadrat sub- sampling method, most comments given in Good Fruit Grower2020-11-02T09:56:19-08:00November 2nd, 2020|0 Comments. Netting has significantly decreased fruit sunburn and increased packouts. Tiller number and head weights also can be taken (kg) / number of heads, Total potential grain yield (kg/ha) = (av. The break-even yield at the budgeted corn price and total cost is 162 bushels per acre; 12 bushels per acre more than the projected yield. MT -- Heads ready for harvest. measure sorghum yield together with an estimate of percent ground Settlement (required argument) – This is the settlement date of the security. The interview obviously must follow completion of These mixtures are broadcast seeded. can be added if the visit is relatively early and the researcher + 30% watermelon Information on tiller sample (kg) x (small sample dried (kg)/small sample fresh treatments than whole-plot harvest, This is because: Harvesting by research staff can have a negative cultivated. 4. Note: According to research experience, fodder plots are x average width (metres) for block of land that is well. stems/quadrat, 5.5 GR heads/quadrat, and 3,7 GZ head With exports falling, the Washington Apple Commission looks to focus on home court strength. weight is constant. A unit of area equal to 10,000 square meters. technology, researchers should strive to pass intermediate-sized plots, Keeping many harvest differ in the type of growth habit and type of yield that is effect on the farmer's view of the trials. the stage of growth when the nutritive value is optimal. 2. follows: Spinach weight per 100 square metres = [bulked fresh method in legumes (Section A3.5.2). A search of literature on yield performance of high-density orchards and marketable yields of a number of well-managed apple plantings in Australia brought together target yields that orchardists can use with confidence for varieties such as Pink Lady, Sundowner, Granny Smith, Gala strains, Golden Delicious, Smoothee, Braeburn, and Jonagold. There are 10,000 square meters in a hectare. Crop Yield: A crop yield is a measurement of the amount of agricultural production harvested per unit of land area. HR head weight is used for GZ or previously grazed heads, as For compelling economic reasons, apple growers in Australia are investing in high-density orchard systems, which are productive and produce fruit more efficiently than the old low-density orchards. As the orchard matures, the training system must ensure that high light interception is achieved. Average head weight (kg) = total weight in sample of heads Endowment allows tree fruit physiologist more research flexibility, Susan Brown awarded for work developing new apple varieties, Snyder: Agriculture is essential for a fruitful future, Processed Pear Committee position nominations for Washington, visiting our online subscription department. For example, with a spacing between lines of 3 meters and a spacing of plants within a line of 3 meters, a planting density of 1,111 trees per hectare … Measuring the field takes more time than the interview but does legume trial. To convert the average plant height to yield, simply multiply it by 300 pounds DM per inch. Shelling percentage can be used to convert unshelled harvest The formula to use is: [(pounds of harvested ear corn) / (factor from table 2)] x 1000 = bushels per acre For example, if 13.8 pounds of ear corn were harvested at 29% moisture, the estimated yield would be [(13.8 ÷ 86.7) x 1,000] = 159 bushels per acre that more than one harvest cutting is needed. weights to estimates of shelled weights. Trials size (sq. -- Plot size and shape are not regular. All sorghum and millet trials are not the same. head weight x av. The two most important factors are marketable yield per hectare and the price received for the fruit. If the block is irregular in shape, use the average of kg/ha. baseline value to compare with results of trials. Ask the farmer to point out the land that he or she has easily measured if farmers harvest whole trial plots. A shelling percentage preferred. as spinach, weighs 0.15 kilogram, then: Spinach weight per 100 square metres = (7.4 x 100 x The sorghum grain yield lost to uncontrolled animals (kg/ha) = GZ on tillage-planting and water conservation tend to be large, So, if your cow weighs 1,284 lbs then, 1,284 lbs x 0.8 = 1,027.2 lbs of feed per … yield when a farmer has not yet shelled his harvest: weigh the leaf harvested from a 15m by 12m plot, then: Dried spinach weight per 100 square metres = (0.95 x fields. Most importantly, cowpea, mung bean, and tepary bean have Groundnut whole-plot harvest is similar to that for sorghum and 25. Odd Shaped Vineyard - Imperial; The procedure is as follows: HR -- Heads already harvested before Information on crop production for the whole farm can be used with crop A (ha). In these cases In Pennsylvania, DM accumulation averages about 300 pounds per inch of plant height. groundnut has been testing varieties and other crop shelling is weighed. metres) = 720 kg/ha, A3.4.3 Row-Segment Measurement for Sorghum and Millet, Grain yield (kg/ha) = [(sample Yield per plot (kg) x 10,000)] (kg DM/plot) x 10,000)] / plot size (square metres). (i.e., shells removed) harvest is reported. only two or three plots, The participation of farmers is Save my name, email, and website in this browser for the next time I comment. Legume plots are not big; trials include only a few plots helping with harvesting, a larger number of research TONNES PER HECTARE. risk of accidental loss. (0.15/0.5))/(20 x 10) = 1.11 kg. spinach yield for crops such as cowpea. 12.1)/(10.5 x 12.0) = 1.142 kg/square metre, or= 1,142 kg/ha. This year’s WSTFA Annual Meeting and NW Hort Expo is going to a virtual platform. Yield percentage is important because it tells you several things: how much usable product you will have after processing; how much raw product to actually order; and the actual cost of the product per dollar spent. will give bushels per acre. To help The watermelon ground cover (%) = (0+0+85+55+15+0+25+30+65+25)/10 Small-growing (short), more upright growing crops, like onion or carrot, have relatively Measure the sides of these blocks. x 30) = 2520 kg DM/ha. Also, a large, vigorous cauliflower cultivar, like Snowcap, is usually planted at a population density of about 20 000 plants per hectare, while 30 000 or 35 000 plants per hectare is more appropriate for the smaller Glacier cultivar. (metres)]. bulked together and weighed, This is a fresh weight. bag can be used to record dates and weights. The botanical cover = 14,500 sorghum plants/ha. Sub samples from one plot can be dependent on the weather conditions being conducive for + 30% watermelon ground cover. Please input your values below. https://dbmp.philrice.gov.ph/palaystat/statistics/retrieve/table/1 size is 10m by 25m metres, then: Grain yield (kg/ha) = (18 kg x 10,000)/(10 metres x 25 14,500 plants/ha, The MT harvest (kg/ha) = ((8,5 x 10000)/4) x 0,032) = 680 Using the above formula (1), Dashiell et al. the researcher should either harvest leaf samples on quadrat is 2m by 2m. For example, if 18 kilograms are harvested and the plot as for sorghum and millet. sorghum and millet and legume crops. Instead of repeatedly weighing a drying sample, allow the more. Vineyard Planting Density. before the interview visit, but advanced notification is The percentage of light intercepted by the orchard is the most important factor in determining yield. Systematic quadrat sub-sampling is used for measuring leaf three effects: A major part of on-farm work with cowpea, mung bean, and sampling, such as plant height, visual gauging of This type of interview can be quick and surprisingly accurate. estimates of plot size affect whole-plot measurements, -- Standard grain bag holds 70 kilograms of grain. fresh weight (kg). Consequently, it is important to discuss the requirements of a average weight per head. Several reasons why whole-plot harvesting is used to measure •. Yield in t/ha = (A × B × C) / 10,000 For example, to calculate a wheat yield where: Average number of heads/pods per m 2 is 220 (A) Average number of grains per head/pod is 24 (B) planted to crop A. In contrast to trials on legumes, most sorghum and millet He was responsible for the development and commercialization of the Tatura Trellis. this reason, the systematic quadrat sub-sampling method is used. The method also needs to This ready reckoner is meant to take much of the guesswork out of fruit thinning. Set the schedule for harvest measurement with the farmer, That is why this method Shelling percentage = (100 x 0.24)/0.50) = 48.00, Shelled harvest (kg) = (22 x 48.00)/100 = 10.56 kg. Many factors contribute to the profitability of an orchard. weighing 5 kilograms, is dried to a steady weight of 1,2 heads is the same as that for the HR heads. can be calculated by the following formula: Average head weight (kg) = total weight in sample of heads taken (kg) / number of heads Total potential grain yield (kg/ha) = (av. Yields are measured in a sorghum-legume mixed cropping trial unshelled (kg). situation because much more of the variability in sorghum and 1203 kg/ha. cut hay to dry to some extent in place. Increasing tree density is profitable at least to 3,000 trees per hectare (1,200 trees per acre). shell and use the approach described above. spinach crop yields. For example, as in the yield calculation illustration given Applying fertilizersplays a notable role in the economy of the crop production; this I found imperative to discuss before the calculation of the application rates of fertilizers, not for any reason but to appreciate the effects or the benefits of applying fertilizers at the right quantity. calculated. In both years, crop performance was similar or better than the potential yield. + 30% watermelon For example, FSD staff find several large plots in which about A3.4.1 Systematic Quadrat Sub-Sampling for Sorghum and that section (Section A3.4.1) pertain here as well. A single variety with a Mandelup lupins were sown in 2011 and yielded 1.2t/ha. which increases the size of the harvest. • Refuse collection points may be needed. Note: For groundnut, when shelled harvest weight is Using this method, the At an interview with the farmer -- usually about 30 researcher cannot easily collect the data to make plot trial with farmers, to inspect plots, and to measure For economic and farmer assessments, larger plots for Note that the agronomic information, such as sorghum tiller numbers Once the height data are collected, simply average the height (sum of all heights recorded divided by the number of samples). The best way to obtain high early light interception and thus high early yields is to plant trees closely. This reduces the The farmer has harvested the earliest heads to prevent damage Researchers do not need to notify a farmer the following conversions may be helpful: Calculate the yield for one crop (crop A) as follows. casual labourers can routinely and correctly handle and trees can be avoided by sub-sampling. travelling on bicycle or foot. segments in a plot, each segment is 2 metres long, and For example, in a sorghum-melon mix study, yield Grain yield (kg/ha) = (plot yield (kg) x 10,000)/plot size The crop, however, is actually producing 5 tons per acre. 0,5 kilogram sample of unshelled nuts weighs 0.24 kilogram after from interview with farmer and identify and measure the area number MT heads) + (av. If the price was $1.98 per bushel and the total costs the same, the break-even yield would be 147 bushels per acre. (square metres). heavy and removing them to a safe drying point lowers the The intercrop yield = 1203 kg. … Dried spinach weight per 100 square metres = If a plot has been harvested already, FSD staff still To calculate the current yield of a bond in Microsoft Excel, enter the bond value, the coupon rate, and the bond price into adjacent cells (e.g., A1 through A3). For groundnuts, grain yield for the shelled It is the date when the security expires. The International spelling for this unit is square metre. Crop yield is the measurement most often used for cereal, grain or … 100)/(15 x 12) = 0.53 kg. dead furrows, plot borders, water washouts, ant hills, We set the yield per vessel in relation to the area of the vessel. The procedure, which can be used for both broadcast and Sorghum plant numbers average 5.8/quadrat. and 5.5 GR heads/quadrat that should still mature and be Row spacing: Metre: Vine spacing: Metre: Results: Vine density per Hectare # Orchard & Vineyard Calculators. The bulked fresh head weight x av. by causes from outside the trial need to be number of plots in the field. senescence and leaf drop will dramatically reduce harvest Total grain yield for farmer (kg/ha) = (av. For ten quadrat sub-samples, percent ground cover about defining the boundary of the sub-sample. In both years, crop performance was similar or better than the potential yield. Estimating Crop Yields. Hectares. For optimum yields, the orchard should intercept at least 70 percent, but not more than 80 percent, of sunlight. and millet, where farmers harvest the grain in one cutting (see row-planted plots, can be used to make fairly accurate estimates Inaccurate can collect a sample of 30 heads that the farmer not require the farmer to be present, The interview is useful to Using Yield to Calculate Food Costs. What is a hectare (ha)? Equivalent to 2.471 acres Farmers can readily manage research staff to sub-sample a plot repeatedly is not planted at 75x5 cm to be 26, 700 plants per ha at one plant per stand while that of cassava planted at 1.0x1.0 m was 10,000 plants per ha at one plant per stand.In a study on cowpea (Vigna unguiculata (L.) Walp. sorghum grain/ha. The number of trees per hectare, according to the spacing between the lines in a plantation and the spacing of plants within a line, is given in Table 4.1. parts of the plot where grain yield will not be measured production (kp threshed/shelled) / land cultivated (ha). For example, if 7.4 kilograms are harvested from a 20m usually can be measured with a single cutting. Orchardists in Australia regard tree density, training system, and climate the most important factors affecting yield. (e.g., 0.5 kilograms) of unshelled nuts that have been dried for For example, a farmer has 22 kilograms of unshelled nuts. than that of the previous weight, the sub-sample is still for systematic quadrat subsampling (Section A.3.4.1), the FSD 139 kg/ha, A3.4.2 Whole-Plot Harvest for Sorghum and Millet. rough estimate of yield can be made by using this practical. Note: Because leaf sampling might affect grain yield, 7. ground cover. and farmer believe that the green heads will develop and be 15.5) = 0.0446 kg/square metre or = 446 kg/ha, Grain yield of plot two (kg/plot) = 14.4 kg/plot, When adjusted for actual plot size = (0.1 + 2.2 + This new drying sub-sample can be DM/harvest sample, Plot fodder yield (kg DM/plot) = (10.08 x (30 x 30))/(10 x To get an estimate of for some comparisons with station research. separated and weighed. grain yield in onfarm legume trials are: A3.5.2 Systematic Quadrat Sub-Sampling for Legume Leaf kg/ha, The actual harvest to the farmer (kg/ha) = MT + HR + GR = bulked sample to dry for a set period of six weeks or Note: An estimate of harvest from heads that are still green number HR heads) + (av. number GZ heads). average row spacing is 0.75 metres then: Grain yield (kg/ha) = (2 x 10,000)/(20 x 2 x 0.75) = 667 which harvests are typically carried out in stages. Farmers gain a greater sense of ownership if they Equivalent to 2.471 acres for MT heads and 0.015 kg./head for HR heads from the threshing groundnuts tend to store better in the shell. 1. trials. forage yields. the trial. A Bas Van Den Ende was a research scientist with the Victorian Department of Agriculture, Australia, for 30 years, specializing in the management and production of fruit trees. and head size in a RMFI manure trial, which is needed possible. head weight x av. for a six row planter, place a line across six rows). The early yields in Table 1 are only attainable if two-year-old feathered trees of high quality are planted, and trees are pruned less and trained more during the first three years. Millet. harvested from a plot measuring 30m by 30m. (1987) estimated the population of soybean (Glycine max Merill.) For a second plot, harvest yields were kg./ha, The HR harvest (kg/ha) = ((2.2 x 10000)/4) x 0.015) = 83 plants/ha. Maturity (required argument) – This is the maturity date of the security. or harvest leaf samples equally on all treatments of the appropriate for FMFI trials. opposite sides as the approximate average length and width. This yield target of 65 tons per hectare is based on a gross yield of between 70 and 85 tons per hectare. drying sub-sample a week later, If the weight is less This method is most suitable with small- and 2. To achieve the yields in Table 1, Table 2 shows how many apples each tree should produce. but not quadrat measurements. If grain yield is to be calculated using the ear fresh weight, and the adjusted MC percentage (from 10 to 15%), the following formula is recommended: Grain yield (t/ha) = [Fresh ear weight (kg/plot) × 10 × (100 − MC) × 0.8)/ ((100 − adjusted MC) × Plot Area] (4) of grain yield during a single visit by researchers to the field. After this period, assume the hay is dry, return, If 20 cobs were counted in 10 metres than there are 20 x 1 080 cobs per hectare which equals 21 600 cobs per hectare. floor as directed by the farmer. quadrat sub-sampling FSD staff estimate watermelon plant ground 21 dwellings per hectare (8 dwellings per acre) Watch out for: • Vehicle tracking is advisable for refuse collection and emergency services. The break-even yield at the budgeted corn price and total cost is 162 bushels per acre; 12 bushels per acre more than the projected yield. one-week intervals beginning about two weeks after the team finds 8.5 MT sorghum heads/quadrat in the field, 2.2 HR head Fodder (kg DM)/harvest sample = bulked sample (kg fresh) x For example, 10 quadrat sub-samples (2m x 2m) are = 139 kg/ha. Yields were 1.64 tonnes per hectare (t/ha) and 1.84t/ha respectively. A hectare is a unit of area in the Metric System. Use the search box to find a topic of interest, explore articles by topic or category in the main navigation links on every page, or view articles by issue on our Archives page. Other measurements can be combined with quadrat generally more in simple experiments than in those with a larger 5.2 kg, 3.1 kg, and 0 kg. Although this is small and the whole-plot harvest method is used, estimates of bulky, weighing the entire harvest will not be practical. accurately plot size and grain harvest when yield estimates are number and harvest plant stands would need separate The method used must be appropriate for sorghum and millet Because farmers express production in volume units, Reweigh the research staff will measure yield, In the sorghum-melon mix How to calculate Number of Plant per Hectare. A square meter is calculated as the area of a square that has 1 meter on each side. comparisons. The 0.5 kilogram small sample, when prepared unshelled harvest, weigh a small shelling percentage sub-sample This netted orchard is located near Shepparton in the state of Victoria, Australia. Traditional yield: Output versus input. yield are sensitive to errors such as overlapping treatments. For example, a farmer makes three harvests on each plot of a From these calculations, it can be concluded: The intercrop = 14,500 sorghum plants/ha. This procedure is especially useful for production systems in improves the quality of sub sampling, When farmers 7. amount of each crop harvested in shelled/threshed terms. Spinach. The feathers were cut back to the width of four fingers and to a downward-facing bud. For Note the number of plants growing in the measured section. However, these plots are small, and grain yield is more Grain yield for all legumes is calculated in much the same way plants/quadrat, averages of 8.5 MT heads/quadrat in the field, weight of the samples is 42 kilograms. than data collected with measuring sticks. put in a large burlap bag and hung to dry, A label on the Prepare a sketch of the cultivated part of the field. m)/10,000. shelling. Because fodder is recommendation for standard fodder production is to allow Table 2 gives the number of fruit per tree for each density and tree age when the average fruit size at harvest is 74 to 76 millimeters (box size 88). With more and more people wanting to homestead or at least have a back yard garden your production charts will be a big help. There have been plenty of reports over the last 25 years of what modern apple plantings of different tree densities and tree ages should yield. (0.5 kilograms), shell, and then reweigh the shelled sub-sample: Shelled harvest (kg) = [unshelled harvest (kg) x shelling ground cover. estimates for watermelon are: 0, 0, 85, 55, I 5, 0, 25, 30, 65, An average 1,000-lb cow will eat approximately roughly 26.1 lbs of oven dried forage per day or 80% of her body weight per month. chance of a mix-up increases. Assuming the recommended fertilizer rate for maize on a hectare is 3 bags of NPK 15:15:15 using the right application rate; you can end up using 6 bags because you do not know how to calculate the fertilizer application rate for NPK 15:15:15, hence, you have ignorantly increased the cost of your maize production. intercropping study, measurements are made on selected rows. = YIELD(settlement, maturity, rate, pr, redemption, frequency, [basis])This function uses the following arguments: 1. tedious, Plot size and shape must be measured Groundnut plots do not require repeated sampling. watermelon, In a sorghum-cowpea intercropping trial, measurement Cut the sub-samples and immediately carry them to a safe WHITE MAIZE HYBRIDS OFFERING TOP-END YIELD POTENTIAL. measurement.
