Studies on grain yield and yield components of long duration pigeonpea (Cajanus cajan L. Millsp) as influenced by planting methods and plant populations.

An experiment was laid out in two consecutive kharif seasons during 2003 and 2004 at Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh to study the effect of planting methods and plant densities on yield and yield attributes in late sown pigeonpea. Experiment consisted four plant populations (88888, 66666, 5333 and 44444 plants ha−1) and two planting methods (Ridge and Flat bed), with four replications in randomized block design. Results revealed that ridge planting method influnced the seed yield and its components significantly with an increase of 27% in grain yield; significant increase in grain yield was also recorded along with simultaneous increase in plant densities.Therefore, it can be said that ridge sowing with high plant density practice in late sown pigeonpea produces maximum grain yield.
