Response of Foliar Spray of Nutrients on Yield and Nutrient Uptake by Black Gram (Vigna mungo L.)

A field experiment was conducted at experimental farm, Department of Agronomy, A field experiment was conducted at experimental farm, Department of Agronomy, Faculty of Agriculture and Veterinary Sciences, Mewar University Gangrar, Chittorgarh (Rajasthan) during Rabi season of 2023-24 to Response of foliar spray of nutrients on yield and nutrient uptake by black gram variety “Pratap Urd-1‟ was used in this study. The result revealed that the maximum yield parameter such as number of pods per plant (15.20), number of seed per pod (6.44), grain yield (11.52 q/ha), straw yield (5.62 q/ha) with application of T9-100% RDF + T7 + Foliar application of ZnSO4 @ 0.2%. The maximum nitrogen content in grain and straw (3.58 and 1.64%), phosphorus (0.39 and 0.48%), potassium content (1.73 and 1.62%) and nitrogen uptake in grain and straw (27.37 and 25.62 kg/ha), phosphorus (4.49 and 7.50 kg/ha) and potassium uptake (19.93 and 25.30 kg/ha) were recorded with T9-100% RDF + T7 + Foliar application of ZnSO4 @ 0.2%. It was concluded that the treatment T9-100% RDF + T7 + Foliar application of ZnSO4 @ 0.2% found significantly higher yield and nutrient uptake by black gram.
