Production potential of rice-based cropping systems in rainfed lowland situation of eastern Uttar Pradesh, India.

摘要

Thirty-six combinations of crop rotation, tillage and fertilizer rate were compared for rice production systems in field trials conducted at Bahraich, Uttar Pradesh during 1986-92. Experiments were conducted in shallow, semi-deep and deep-water conditions or in a flood-prone situation. Yields of each crop, benefit:cost ratio and rice-equivalent yield are tabulated.
