Abstract
The field experiment was carried out at Crop Research Farm (CRF) during the Zaid season (march to June – 2022) in the Department of Agronomy at SHUATS in Prayagraj (UP) on soil with sandy loam in texture to investigate the effect Molybdenum and Foliar application of Boron on Growth and Yield of Cowpea. The treatments consist of three doses of Molybdenum viz., 0.5kg ha-1, 0.75kg ha-1 and 1kgha-1 and Boron 0.5% at 3 intervals viz., 30DAS, 45DAS and 30DAS & 45DAS whose effect is observed on Cowpea (var. Gomati). The experiment used a Randomized Block Design with ten treatments replicated three times. The treatment with application of Molybdenum 1kg ha-1 + Boron 0.5% at 30DAS & 45 DAS recorded significantly higher number of pods per plant (16.73), number of seeds per pod (11.67), seed index (18.38g), seed yield (1.59 t ha-1) and Haulm yield (4.16 t ha-1) and BC ratio (1.97) compared to other treatment combinations.
