Rainwater Conservation Techniques with Integrated Phosphorus Management on Productivity of Pigeonpea under Dryland Conditions

Abstract

A field experiment was conducted on effect of in-situ rainwater conservation techniques with integrated phosphorous management on productivity of pigeonpea under dryland condition during the kharif season 2007-08 to 2011-12 to find out the effect of land configuration with different phosphorus sources on productivity of pigeonpea. The experiment was laid out in factorial randomized block design with three replications. The treatment consisted of two land treatments viz., M 1 : flat sowing with three hoeing at 3 rd , 5 th and 8 th weeks after sowing, M 2 : flat sowing with one hoeing at 3 rd week and opening of ridges and furrows at 30 days after sowing with five integrated phosphorus sources viz.
