The hectarages of basmati rice, Irri rice, and wheat increase in Model 6 when extra land is available, suggesting that these crops are limited by livestock feed requirements.
These simulations included relaxing exogenous livestock numbers and selected crop hectarage constraints, and requiring that green forage be fed in the season grown.
The validation of Model 1 was undertaken by comparing its solution with 1987-88 crop hectarage, and livestock and poultry numbers at the national and provincial levels.
a) Model 2 drops hectarage restrictions on kharif fodder, kharif pulses, and all oilseeds from Model 1.
In Model 2, the hectarage of pulses during kharif is far greater than actual, but none is grown in rabi.
Another reason for the low hectarage of sugarcane, coarse grains, and kharif fodder is that two joint products are produced from oilseeds, cake, and oil.
