There has been a decline in the rate of growth of cross sown area, in particular under non-food crops, in the decade starting from 1967-68 compared to the fifteen years ending in 1964*65, but the output (and yield per unit of area) of food crops and all crops grew more or less uniformly over the entire period 1949.50 to 1977-78 with no evidence of either acceleration or deceleration since 1967-68.
