Productivity and economics of rice based cropping sequences under mid-hill conditions of Himachal Pradesh, India.

摘要

In a field experiment in 1989/90 to 1992/93 at Malan, Himachal Pradesh, India, comparisons were made of rice followed by potatoes, wheat, Brassica napus, linseed [Linum usitatissimum] or gram [Cicer arietinum]. Rice yield did not differ much betweenthe different cropping sequences, but the rice-potatoes sequence gave the greatest overall yield and the highest net returns, followed by rice-wheat and rice-gram.
