Abstract

Investigations were carried out in the field in kharif 89 and rabi 90 employing the variety Co.1 with three irrigation scheduling viz., 60, 80 and 100 mm of cumulative pan value and six management (ameliorative) practices comprising, incorporation of decomposed coir pith (coconut fibre waste) at 12.5 t ha", split application of potassium at 40 kg ha (50 per cent basal and 50 per cent top dressed at 30 and 60 DAS), spraying cycocel (250 ppm) at peak flowering stage, spraying 0.5 per cent Kel at peak flowering stage, incorporation of crystal rain (Soil moisturiser) at 12 kg ha and a control. The crop growth and yield was better in kharif than in rabi. Irrigation at 60 mm pan value improved the crop growth by recording more LAI, RGR, CGR, lower canopy temperature, transpiration rate higher RLWC and SDR which resulted in higher seed yield. Among the management practices, the foliar application of cycocel, and Kel, separately maintained higher tissue water content, followed by split application of potassium and other treatments. Irrigation at 60 mm pan vale in combination with cycocel at 250 ppm recorded maximum seed yield in both the season. followed by split application of potassium in kharif and coirpith in rabi seasons respectively
