Abstract

The goal of research was to found the “integrated effect of planting geometry and growth retardants on yield and economics of pigeonpea under rainfed” during kharif season 2019-20 and 2020-21. A field trial was conducted at experimental farm of Department of Agronomy VNMKV, Parbhani. Planting geometry and growth retardants are important factor for improving yield and economics. In this study, the main plot consisted four planting geometry P1- 60 cm × 20 cm, P2- 90 cm × 20 cm P3- 90 cm × 30cm (P4- 120 cm × 20 cm and in sub plot consisted four growth retardant application (30 and 60 DAS) viz. G1- Control, G2- CCC @ 60 ppm, G3-Paclobutrazol @ 100 ppm, G4-Paclobutrazol @ 125 ppm. The experiment was conducted into split plot design with sixteen treatment combination. The result revealed that, significantly higher seed yield (kg ha-1) was recorded with plating geometry 120 cm × 20 cm. Among all treatments, foliar application of Paclobutrazol @ 125 ppm was recorded higher seed yi
