Effect of FYM, Phosphorus and PSB on Growth, Yield Attributes, Quality, Nutrient Content (%) and Uptake by Kharif Green Gram [Vigna radiata (L.) Wilczek]

Abstract

This experiment was carried out for two consecutive years (2020 and 2021) during Kharif season at Student’s Instructional Farm (SIF) of Department of Agronomy, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur, Uttar Pradesh, India to assess the effect of Farm Yard Manure (FYM), phosphorus levels and Phosphate solubilizing bacteria (PSB) on growth and yield of Green gram with variety Shweta (K.M. 2241) was laid out in Factorial Randomized Block Design (FRBD) and replicated thrice. This experiment included 20 treatment combinations, the levels of FYM viz., control (F0), 1.0 t (F1), 2.0 t (F2) and 3.0 t (F3) and levels of phosphorus viz., PSB only (P1), 20 kg P2O5 (P2), 20 kg P2O5 + PSB (P3), 40 kg P2O5 (P4) and 40 kg P2O5 + PSB (P5). The result of this study showed the interaction effect of FYM, phosphorous & PSB were non-significant. In the different levels of FYM, the 3.0 tons ha-1 FYM resulted in significantly higher growth attributes viz., plant height (40.60cm) at maturity, No. of branches plant-1 (4.95) at maturity, number of nodules plant-1 (24.85) at 60 DAS and dry weight of nodules plant-1 (14.34g) at 60 DAS, yield attributes viz., number of pods plant-1 (14.70), weight of pod plant-1 (7.44g), pod length (6.55cm) , and test weight (41.36g), yield viz. grain or seed yield (894kg ha-1) and quality parameters viz., protein content (23.90%), protein yield (214kg ha-1), nutrient contents i.e. nutrients uptake by grain and straw of Green gram compared to other treatments and control. Among the different levels of phosphorous & PSB, 40 kg P2O5 ha-1 + PSB resulted the highest values of growth attributes viz., plant height (38.54cm) at maturity, No. of branches plant-1 (4.52) at maturity, number of nodules plant-1 (23.19) at 60 DAS and dry weight of nodules plant-1 (13.42g) at 60 DAS, yield attributes viz., number of pods plant-1 (13.99), weight of pod plant-1 (6.57g), pod length (6.35cm), and test weight (40.85g), yield viz. grain or seed yield (825 kg ha-1), and quality parameters viz., protein content (23.84%), protein yield (197kg ha-1), nutrient contents i.e. nutrients uptake by grain and straw. Thus, it is possible to maximize the growth attributes, yield attributes, yield and quality of Green gram with application 3.0 tons ha-1 FYM and 40 kg P2O5 ha-1 + PSB.
