Question
Calculate the cropping intensity of
rice-wheat-ragi-fallow rotation if farm area is 2 ha.Solution
The duration of rice-wheat-ragi-fallow is 2 year and farm is 1 ha. So, net cultivated area = Farm area * duration of rotation = 2 * 2 = 4 ha Area under rice = 2 ha Wheat = 2ha Ragi = 2 ha So total cropped area = 2+2+2 = 6 ha Cropping intensity = total cropped area/net cultivated area * 100 = 6/4 * 100 = 150%
