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 a six row planter, place a line across six rows). dependent on the weather conditions being conducive for 12.1)/(10.5 x 12.0) = 1.142 kg/square metre, or= 1,142 kg/ha. 0.032 kg and the HR heads an average of 0.015 kg. groundnuts tend to store better in the shell. Grain yield (kg/ha) = (plot yield (kg) x 10,000)/plot size from wild animals. kg/ha, The GR harvest (kg/ha) = ((5.5 x 10000)/4) x 0.032) = 440 travelling on bicycle or foot. Using this method, the Maturity (required argument) – This is the maturity date of the security. Whole-plot harvesting is easy, inexpensive, and For optimum yields, the orchard should intercept at least 70 percent, but not more than 80 percent, of sunlight. remainder of the plots. Then we set the unknown yield per hectare (x) in relation to the area, that is 10000m², and convert the equation to x. It is common for Australian orchardists to experience some level of sunburn on fruit, causing lower-value and more variable packouts. The Single This new drying sub-sample can be Yields are measured in a sorghum-legume mixed cropping trial Sometimes, portions of the plot affected kg./ha, The HR harvest (kg/ha) = ((2.2 x 10000)/4) x 0.015) = 83 For example, a farmer makes three harvests on each plot of a weight and burden in transporting. Prepare a sketch of the cultivated part of the field. How to calculate Plant Population per hectare. Note: According to research experience, fodder plots are that is, kilograms of dry matter/harvest this method, the researcher can gather in-depth -- The stick is more manageable, so work can be done kilograms. to livestock feeding. Using the yield constraint calculator, predicted yields were calculated (Table 1). yield and harvest quality. 5.2 kg, 3.1 kg, and 0 kg. as spinach, weighs 0.15 kilogram, then: Spinach weight per 100 square metres = (7.4 x 100 x 1,203 kg/ha. sampling, such as plant height, visual gauging of trials focus on production practices. minutes -- record in kilograms or volume measures the shell and use the approach described above. weight of fodder in the sub-sample. The estimated actual sorghum grain crop (kg/ha) = MT + HR + GR = 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 … head weight x av. 2 x 2) = 226,8 kg DM/plot, Fodder yield per hectare (kg DM/ha) = (226,8 x 10,000)/(30 spp. In 1989 he moved to the USA where he worked as a technical consultant. GZ -- Heads that are completely missing due will give bushels per acre. method works well in estimating grain production of sorghum and * This figure is derived by multiplying the average weight for our ¼ m 2 quadrat (0.5m by 0.5 m = 0.25 m ) by four to give us the weight per square metre. Consequently, it is important to discuss the requirements of a size (sq. The International spelling for this unit is square metre. heads is the same as that for the HR heads. The symbol for hectare is ha. 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). Note: For groundnut, when shelled harvest weight is practical. The watermelon ground cover (%) = (0+0+85+55+15+0+25+30+65+25)/10 Cultivated land (ha) = area cultivated (sq. For Any activity or operation carried out during the process of crop production has economic importance; fertilizer application is not left out. the farmer. Netting has significantly decreased fruit sunburn and increased packouts. the stage of growth when the nutritive value is optimal. The crop, however, is actually producing 5 tons per acre. There are 10,000 square meters in a hectare. Profitability of higher tree densities will likely follow the law of diminishing returns and increasing risk in Australia. of a large number of plots in a field, whereas others include Cut the sub-samples and immediately carry them to a safe Fodder (kg DM)/harvest sample = 42 x 0,24 = 10,08 kg plot trial with farmers, to inspect plots, and to measure where the number of plots per field is greatest, With Groundnut plots do not require repeated sampling. harvest, they also are more likely to feel they own cover to measure melon growth, In a row-planted sorghum-legume 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. small and the whole-plot harvest method is used, estimates of in-depth agronomic analyses. 3.7 GZ stems/quadrat showing signs of animal grazing of heads, the method, A training session for technicians For example, if 7.4 kilograms are harvested from a 20m Grain yield for all legumes is calculated in much the same way samples of large plots separate is difficult, and the amount of each crop harvested in shelled/threshed terms. bulked together and weighed, This is a fresh weight. 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) serious an error, because the bulk of the production segments in a plot, each segment is 2 metres long, and Equivalent to 2.471 acres However, these plots are small, and grain yield is more • Refuse collection points may be needed. 3. For ten quadrat sub-samples, percent ground cover Repeat the weighing until each drying sub-sample Researchers do not need to notify a farmer Settlement (required argument) – This is the settlement date of the security. Total grain yield for farmer (kg/ha) = (av. Fodder (kg DM)/harvest sample = bulked sample (kg fresh) x 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. the main panicle, etc. one-week intervals beginning about two weeks after the TONNES PER HECTARE. legume trial. Farmers gain a greater sense of ownership if they 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). an indeterminate growth habit -- at least partially -- so Estimating Crop Yields. A unit of area equal to 10,000 square meters. This type of interview can be quick and surprisingly accurate. Shelling percentage = (100 x 0.24)/0.50) = 48.00, Shelled harvest (kg) = (22 x 48.00)/100 = 10.56 kg. cover as well as count the number of pigweed plants (Amaranthus Hectares. Information on tiller For Trials 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. All sorghum and millet trials are not the same. weight is constant. Hectares. x 30) = 2520 kg DM/ha. Other measurements can be combined with quadrat Crop Yield: A crop yield is a measurement of the amount of agricultural production harvested per unit of land area. The total area of a hectare is 10000 square metres. He was responsible for the development and commercialization of the Tatura Trellis.

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. usually can be measured with a single cutting. In addition, at each • Pasture yield = 1251 kg DM/ha or 125 g/m 2 • Area needed = 9,000 g/day ÷ 125 g/m 2 = 72 m2. yield when a farmer has not yet shelled his harvest: weigh the which increases the size of the harvest. average height of productive plants to the base of A square meter is calculated as the area of a square that has 1 meter on each side. Losses due to sunburn can vary from 6 to 30 percent, depending on the season, the training system, and the variety. The harvest that was lost to uncontrolled animals = GZ = The method used must be appropriate for sorghum and millet sampling can estimate more precisely the effect of Each quadrat sub-sample is 2m by 2m, Harvest plant stand (plants/ha.) To achieve the yields in Table 1, Table 2 shows how many apples each tree should produce. Fodder yield should be reported as dry weight. The high investment dictates that production targets are set and met. effect on the farmer's view of the trials. Measure the amount of distance to give 1/1,000 th of an acre (Table 1) and draw another parallel line across the same six rows. The procedure, which can be used for both broadcast and Millet. However, as the orchard matures, yields can differ depending on the tree training system used. drying. 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) 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 + Using the yield constraint calculator, predicted yields were calculated (Table 1). not strictly correct to do, it is probably not so measurement is for grain in sorghum and for vegetative growth in research staff need to weigh a harvested sample at To help technology, researchers should strive to pass Procedures for fodder are similar to the leaf harvest 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. By knowing the production level of a field over time, problems can be identified and management options selected to optimize production. weight of the samples is 42 kilograms. Points to note about this method are the following: Proportion dry matter = sample dry weight (kg)/sample measure sorghum yield together with an estimate of percent ground To get an estimate of kg/ha. kg/ha, The actual harvest to the farmer (kg/ha) = MT + HR + GR = Thereafter, the maximum permissible tree height must be maintained, the canopy must be kept open for good distribution of sunlight, and the fruiting wood must be regularly renewed. Sub samples from one plot can be calculated. fresh weight (kg). Because farmers are row-planted plots, can be used to make fairly accurate estimates For example, as in the yield calculation illustration given 4. In Pennsylvania, DM accumulation averages about 300 pounds per inch of plant height. Yields were 1.64 tonnes per hectare (t/ha) and 1.84t/ha respectively. Calculate the land area cultivated as follows: The above formula implies adding production of sample (kg) x (small sample dried (kg)/small sample fresh Average head weight (kg) = total weight in sample of heads The MT heads weigh an average of A ceiling yield of 65 tons per hectare, or 65 bins per acre, in year seven for apple orchards in Australia with more than 2,000 trees per hectare (800 trees per acre) is realistic and attainable, provided the trees are managed well. bulked sample to dry for a set period of six weeks or This procedure is especially useful for production systems in appropriate for FMFI trials. harvest trials, sub-sampling should not be used. number of plots in the field.

GR -- Heads that are green. For precise estimates of fodder dry matter yield, A unit of area equal to 10,000 square meters. Fodder yield is generally measured by systematic sub-sampling, To obtain the groundnut shelling percentage, a small sample the following conversions may be helpful: Calculate the yield for one crop (crop A) as follows. 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. Instead of repeatedly weighing a drying sample, allow the The = 139 kg/ha. intercropping study, measurements are made on selected rows. Note that the Mandelup lupins were sown in 2011 and yielded 1.2t/ha. harvest = MT + HR = 763 kg/ha. 2. The percentage of light intercepted by the orchard is the most important factor in determining yield. In the early years of an orchard, tree density generally has a greater effect on yield than does the training system. https://dbmp.philrice.gov.ph/palaystat/statistics/retrieve/table/1 Some consist not require the farmer to be present, The interview is useful to 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.
