Effect of spacing and foliar spray of micronutrients on growth and yield of cluster bean (Cyamopsis tetragonoloba (L.) Taub.)

Abstract

An experiment was conducted, with a view to study the effect of spacing and foliar spray of micronutrient on growth and yield characters on cluster bean. Among levels of spacing, S3 (45 cm × 30 cm) was found best in fresh weight, dry weight, number of clusters plant-1, number of pods cluster-1, number of pods plant-1, total yield plant-1, pod yield ha-1. However, S1 (45 cm × 20 cm) level of spacing gave maximum plant height and stem diameter. Foliar spray of 0.5% FeSO4 + 0.5% ZnSO4 showed maximum stem diameter at 90 DAS, fresh weight of plant (148.64 g), number of clusters plant-1, number of pods cluster-1, number of pods plant-1, total pod yield plant-1, respectively. The treatment combination S3F3 {(45 cm × 30 cm) + (0.5% FeSO4 + 0.5% ZnSO4)} showed significantly maximum number of pods plant-1, pod yield plant-1 and hectare-1.
