Effect of seaweed sap (Kappaphycus alvarezii) and micronutrients on growth and yield of moong bean (Vigna radiata L.)

Abstract

The field experiment was conducted at Crop Research Farm (CRF), Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.) during Zaid season 2023 on moong bean crop. The treatment consisted of 2 levels of Seaweed Sap (Kappaphycus alvarezii) (5% and 7.5%), and 4 levels soil application of micronutrients, Boron (1.5 and 3.0 kg/ha) and Molybdenum (0.75 and 1.5 kg/ha) and control. The experiment was lay out in Randomized Block Design (RBD) with 9 treatments and replicated thrice. Application of Seaweed sap (Kappaphycus alvarezii) 7.5% and Soil application of B 3.0 kg/ha produced growth parameters like higher plant height (43.35 cm), number of nodules/plant (31.89), number of branches/plant (6.14), plant dry weight (18.57 g) and yield attributes like maximum pods/plant (30.58), maximum seeds/pod (8.35), test weight (37.76 g), seed yield (1248.85 kg/ha) and Stover yield (2304.97 kg/ha).Treatment combination with Seaweed sap (Kappaphycus alvarezii) 7.5% and Soil application of B 3.0 kg/ha highest gross return (₹.122958/ha), net return (₹.82481/ha) and benefit cost ratio (2.04) when compared to other treatment.
