Influence of row proportions on yield and yield components of pigeonpea in intercropping system of pigeonpea [Cajanus cajan (L.) Millsp.] and ashwagandha (Withania somnifera Dunal)


Journal Title:International Journal of Agricultural Sciences

Field experiment was conducted at Agricultural College Farm, Raichur, Karnataka on medium deep black soils duringKharif seasons of 2005 and 2006 to study the influence of row proportions of pigeonpea and ashwagandha in the intercropping system on yield and yield components of pigeonpea. The seed yield of pigeonpea in sole cropping system (15.80 q ha-1) was found to be significantly higher than that recorded under different row proportions of pigeonpea and ashwagandha (11.34 to 14.04 q ha-1). Similar trend was noticed with respect to yield components viz., dry matter accumulation in reproductie parts, number of pods per plant, seed weight per plant, seed number per plant and 100-seed weight. Among the different row proportions, the pigeonpea seed yield produced under 2:4 (14.04 q/ha) and 1:2 (13.95 q ha-1) row proportions were higher by 24 and 23 per cent when compared to the seed yield recorded under 2:1 row proportion of pigeonpea and ashwagandha (11.34 q/ha). The same trend was indicated in the yield components of pigeonpea
