Effect of different sowing dates and weed management on cluster bean (Cyamopsis tetragonoloba L.)

Abstract

A field experiment was conducted at “Effect of Different Sowing Dates and Weed Management on Cluster Bean (Cyamopsis tetragonoloba L.)” conducted during kharif 2024 at Agriculture farm, Suresh Gyan Vihar University, Jaipur on loamy sand soil. Sowing of clusterbean on 15th July recorded significantly plant height, dry matter accumulation, higher pods per plant, seed per pod, seed, straw and biological of clusterbean as compared to 30st July but remained statistically at pat with 1th July. The maximum plant height, dry matter accumulation, number of pods per plant, seed per pod, seed, straw and biological of clusterbean were recorded with pendimethalin 750 g PE fb Imazethapyr @ 70 g/ha PoE, which was statistically at par with weed free treatment. The maximum net return and B: C ratio recorded with sowing of clusterbean on 15th July as compared to 1st and 30th July. Pendimethalin 750 g PE fb Imazethapyr @ 70 g/ha PoE significantly increased net returns and B: C ratio compared to rest of weedy check, and remined statistically at par with weed free and Imazethapyr @100 g/ha.
