In order to estimate the yield per acre of crop, an area frame is prepared which includes all the concern crop growing fields in sample villages and in each village three fields (each field has two plots = six plots) measuring 20’x15’ / 16’x12’ for major and minor crops respectively are randomly located through a very scientific method. The crop of these plots is harvested by the Crop Reporter when the crop is fully matured. The produce of the plots is threshed, winnowed, cleaned and weighed carefully.
