Productivity of rabi pigeonpea (Cajunus cajan L. Milsp.) as influenced by scheduling of irrigation.
Abstract: A field experiment was conducted at the Instructional Farm, Jaguli, Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal during winter seasons for three consecutive years to study the effect of irrigation at different physiological growth stages like branching (B), flowering (F) and pod formation (P) stages and their different combinations on the yield components and yield of pigeonpea. Yield and yield components were significantly influenced by the application of irrigation. Three irrigations applied one each at branching, flowering and pod formation stages produced the highest seed yield; but it was at par with two irrigations applied at branching and flowering stages during all the three years. Irrigation at branching and flowering was found essential for higher seed production in pigeonpea grown during winter months. Single irrigation at flowering stage produced maximum seed yield .The increase in seed yield over control (rainfed) was 772 Kg.ha-1 with irrigation at B+F+P, 703 Kg.ha-1 at B+F and 548 Kg.ha-1 at F stages.
