Any activity or operation carried out during the process of crop production has economic importance; fertilizer application is not left out. 12.1)/(10.5 x 12.0) = 1.142 kg/square metre, or= 1,142 kg/ha. Equivalent to 2.471 acres Using the yield constraint calculator, predicted yields were calculated (Table 1). harvested from a plot measuring 30m by 30m.
