Abstract

A field experiment was conducted during 1995 at the Regional Agricultural Research Station, Nepalgunj in west Nepal to evaluate the productivity of nine different croppin sequences and their effects on the productivity of rice  and potato. The productivity of rice was highest (5.9 t ha-1 ) in dhaincha-rice-potato cropping pattern (CP) which was at par with rice bean-fallow-rice but significantly superior to all other CPs. The productivity of tuber was highest (10.3 t ha-1) in dhaincha-rice-potato as compared with other CPs receiving equal amount of fertilizers. The total productivity (economic yield) was highest (29.4 t ha--1 yr-1) in okra-rice-potato pattern receiving higher dose of fertilizers (60:40:30 kg NPK ha-1 ). There was yield increment in both rice grain and potato tuber as biomass incorporated in soil was increased. This suggests that rotation of crops with legumes, at least once a year, is an important factor in sustaining the production systems.
