Effect of different levels of micronutrients on crop growth and yield parameters of Green gram (Vigna radiata L.) Cv. IPM 02-03

Abstract

A field study was conducted on the “Effect of different levels of Micronutrients on crop growth and yield parameters of Green gram [Vigna radiata L.] Cv. IPM 02-03, at the Soil Science Research Farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during Kharif season 2018. The soil of experimental area falls in order Inceptisol and soil texture was sandy loam. The result showed plant height 52.9 cm at 45 DAS, number of leaves plant-1 18.0 at 45 DAS, number of pods plant-1 21.3 at 60 DAS, Test weight 36.6 g, Seed yield 32.37q ha-1 were significantly increased with the application of recommended dose of NPK fertilizers and 100% ZnSO4 and 100% FeSO4 fertilizers. The Maximum no of seeds per pod (9.16) at 60 DAS was obtained in T6 – [RDF + Zn@25 kg ha-1+ Fe@10 kg ha-1 ]. Growth parameters and yield parameters increased significantly in T8 and T6 treatments. The lowest values related to all parameters were obtained in control plot treatment. Benefit cost ratio (B:C) 1:4 was highest in T6 – (i.e. RDF + Zn@100%+ Fe@50% kg ha-1) was more profitable 135020.00 Rs ha-1 than any other treatments and recommendation.
