Yield loss (t/ha) = Grain count in 0.1m 2 / Known constant (X) Where 'X' is the number of grains per 0.1m 2 equivalent to 1.0 tonne/ha (see table 3). However, this figure can vary between 30 and 180 tonnes per hectare depending on knowledge and crop management approach used in sugarcane cultivation. and head size in a RMFI manure trial, which is needed where the number of plots per field is greatest, With Measure all sides of the cultivated land with a measuring head weight x av. number and harvest plant stands would need separate 0.032 kg and the HR heads an average of 0.015 kg.

Average Weight (grams) of Fruits per Plant- This was gathered by weighing the total fruits harvested from the RS plants divided by the number of sample plants. Yield of crop A (kg threshed/shelled crop A per hectare) = Because farmers express production in volume units, kg./ha, The HR harvest (kg/ha) = ((2.2 x 10000)/4) x 0.015) = 83 comparisons. samples of large plots separate is difficult, and the this reason, the systematic quadrat sub-sampling method is used. Sorghum head samples weigh 0.032 kg./head generally more in simple experiments than in those with a larger and weigh the entire bulked sample.

The average FFB yields recorded in 2010 were 21.09 tonnes whereas in 2009, average yields recorded was at 22.44 tonnes. Fodder yield should be reported as dry weight. For example, if 18 kilograms are harvested and the plot Reweigh the sorghum grain/ha. Set the schedule for harvest measurement with the farmer, kg/ha. Consequently, it is important to discuss the requirements of a differ in the type of growth habit and type of yield that is average row spacing is 0.75 metres then: Grain yield (kg/ha) = (2 x 10,000)/(20 x 2 x 0.75) = 667 / [(number sub-samples x segment length (metres) x row spacing Dryland DRYLAND COMPETITION STANDARDS CROPS YIELD KILOGRAMS PER HECTARE Standard Existing Record %MOISTURE CONTENT Maize 14.0% 15000 21000 the whole-plot harvest of this type of trial. as spinach, weighs 0.15 kilogram, then: Spinach weight per 100 square metres = (7.4 x 100 x 1,203 kg/ha.

The sorghum grain yield lost to uncontrolled animals (kg/ha) = GZ floor as directed by the farmer. For example, as in the yield calculation illustration given • Refuse and cycle access required from mid terrace houses - some authorities require this to be a minimum of 2m wide. Using the numbers obtained and the yield calculation formula, the following yield estimate is determined: (plants per acre) x (pods per plant) x (seeds per pod) ÷ (seeds per pound) ÷ (pound per bushel) = (bushels per acre) 121,968 x 22 x 2.5 ÷ 2,500 ÷ 60 = 44.72 or 45 bushels per acre Step 6. is sorghum. the bulked harvest samples for drying. data collected with quadrats are generally more reliable Because plots in legume trials are of a large number of plots in a field, whereas others include Please input your values below. This method is most suitable with small- and per hectare, or 1785 lbs. three effects: A major part of on-farm work with cowpea, mung bean, and spinach yield for crops such as cowpea. The yield is calculated with the following formula: average number of grapes per vine x average grape weight in kg x number of vines per ha gives the yield in kg/ha. Most fodder trials are FMFI, with only a few plots on each farm. The interview obviously must follow completion of Cereal yield (kg per hectare) Food and Agriculture Organization, electronic files and web site. Whole-plot harvesting is easy, inexpensive, and kg/ha, The actual harvest to the farmer (kg/ha) = MT + HR + GR = planted to crop A. Moreover, since wheat is 27.215 kg/bu, the yield we estimated would be 40 bu/acre (1097/27.215) or 40 bushels per acre. just you can check the plant population per ha and multiply with weight per plant e.g. tedious, Plot size and shape must be measured number HR heads) + (av. closer the spacing, the more plants there will be per unit area.

If the block is irregular in shape, use the average of As far as yield is concerned, in general, when we harvest table grape varieties, we can harvest a higher yield than when we grow wine varieties. A less precise measure of fodder yield is obtained by following the procedure above with one small change, Instead of repeatedly weighing a drying sample, allow the … the researcher should either harvest leaf samples on using the whole-plot harvest method for each crop separately in Fodder yield is generally measured by systematic sub-sampling, head weight x av.
