Crop Diversification With Ricebean-Based Intercropping Systems For Maximising Productivity, Profitability and Energy Use Efficiency in Rainfed Upland

摘要

A field experiment was conducted at the Central Research Station, Orissa University of Agriculture and Technology, Bhubaneswar during kharif seasons of 2007 and 2008 to study the performance of ricebean-based intercropping systems in rainfed upland. The soil was well drained loamy sand in texture with acidic reaction (pH - 5.6), low in available N (230.4 kg ha~(-1)), medium in available P (14.6 kg ha~(-1)) and K (164.2 kg ha~(-1)). The experiment comprised of 10 treatments laid out in a randomized block design with 3 replications. The treatments were ricebean (sole), maize (sole), arhar (sole), sorghum (sole), ricebean + maize (2:1), ricebean + maize (4:2), ricebean + arhar (2:1), ricebean + arhar (4:2), ricebean + sorghum (2:1), ricebean + sorghum
