EFFECT OF POST-MONSOON IRRIGATION, RHIZOBIUM INOCULATION AND NITROGENON YIELD AND YIELD ATTRIBUTES OF PIGEONPEA (CAJANUS-CAJAN)

A field experiment was conducted during 1989 and 1990 to study the eff ect of post-monsoon irrigation, Rhizobium inoculation and nitrogen on yield and yield attributes of 'BDN 2' pigeonpea [Cajanus cajan (L.) Mi llsp.] in Vertisol of south Gujarat. irrigation treatments except cont rol did not differ significantly for their effect on grain yield but g ave significantly higher grain yield over no irrigation (control). Amo ng the irrigated treatments, irrigation water : cumulative pan evapora tion (IW : CPE) ratio of 0.25 showed its superiority to the others and recorded the higher grain yield of 17.39 q/ha. The seed treatment wit h Rhizobium did not exert its significant effect on seed yield, while the application of nitrogen @ 20 kg/ha nave significantly highest (18. 32 q/ha) grain yield.
