Effect of fertilizer levels and foliar application of nutrients on growth and flowering of cowpea [Vigna unguiculata (L.) Walp.]

Abstract

An experiment entitled “Effect of fertilizer levels and foliar application of nutrients on cowpea [Vigna unguiculata (L.) Walp.]” was carried out at Vegetable Research Farm, Regional Horticultural Research Station, ASPEE College of Horticulture, Navsari Agricultural University, Navsari during Summer-2023. It was taken out with two factors having fertilizer levels viz., F1: 100% RDF (20-40-00 NPK kg ha-1), F2: 80% RDF (16-32-00 NPK kg ha-1), F3: 60% RDF (12-24-00 NPK kg ha-1) and foliar application of nutrients namely N1: No spray, N2: 2% Novel Organic Liquid Nutrient, N3: 3% panchagavya, N4: 0.5% Water soluble fertilizer (19:19:19 NPK). All the treatment combinations were replicated thrice and laid out in a randomized block design with factorial concept in Gujarat Navsari Cowpea 9 variety. T2 [100% RDF (20-40-00) + 2% Novel Organic Liquid Nutrient] was recorded with the superior results on flowering and growth parameters as compared to the other treatments.
