Bioeconomic Assessment of Direct-seeded Rice-based Intercropping Systems Under Strip Plantation

Muhammad Saeed, Ata Ullah, Riaz Ahmad and Abdul Jabbar    

Abstract: Bioeconomic efficiency of different rice-based intercropping systems under different patterns of strip plantation was determined at Faisalabad during the year 1997. Strip plantation of rice comprised 45-cm spaced 2-row strips, 75-cm spaced 4-row strips and 105-cm spaced 6-row strips while intercrops were maize, cowpea, sesbania and ricebean. All intercrops were utilized as green fodder crops. Although all intercrops caused substantial reduction in both plant biomass and paddy yield ha -1 of the associated rice yet additional fodder yield from each intercrop not only compensated the reduction in plant biomass and paddy yield of rice but also increased farm net income by 19.69 to 125.33 per cent. Thus both legume (cowpea, sesbania, ricebean) and non-legume (maize) fodder crops can be intercropped in the upland rice seeded on a well prepared seedbed in 75-cm spaced 4-row strips in order to increase farm income per unit area. Maize intercropping gives the maximum net income. Besides neither planting pattern nor intercropping affect the qualitative traits such as proportion of normal, fertile, sterile, abortive and opaque spikelets in a panicle of rice.
