Effect of foliar nutrition on dry matter production, yield attributes and yield of cowpea (Vigna unguiculata. L. Walp)

A field experiment was conducted to investigate the effect of foliar nutrition on growth and yield of cowpea in Northern Eastern Zone of Tamil Nadu” in clay soil at SRM College of Agricultural Sciences, Baburayanpettai during summer 2024. The experiment treatments consisted of different organic and inorganic foliar nutrition were applied and this research trial was laid out in a randomized block design (RBD) with seven treatments that are replicated thrice. Results revealed that foliar spray of pulse wonder 1% @ 30 and 45 DAS recorded significantly higher plant height (40.25 cm), leaf area index (4.83), dry matter production (21.08 g plant-1) and yield attributes viz., higher number of pods plant-1 (25.32), pod length (13.33 cm), number of seeds pod-1 (12.10), 100 seeds weight (11.25g), grain yield (1003 kg ha-1 ), and stover yield (2475 kg ha-1) compared to rest of all the foliar nutrition treatments.
