Integrated Nutrient Management for Optimum Growth Traits and Yield of Soybean Crop (Glycine max L. Merr.)

Abstract

A field experiment was conducted during kharif season of 2019 at the Experimental Farm, Department of Agronomy College of Agriculture, Latur to study “Integrated Nutrient Management in Soybean (Glycine max L.)”. The objective of experiment was to find out the effect of different organic and inorganic fertilizers on growth and yield of soybean. The experiment was laid out in a randomized block design with nine treatments and replicated thrice. The treatments were T1 – 100 % RDF, T2 – 100 % RDF + FYM @ 5 t ha-1, T3 – 75 % RDF + FYM @ 5 t ha-1, T4 – 100 % RDF + FYM @ 2.5 t ha-1, T5 – 75 % RDF + FYM @ 2.5 t ha-1, T6 – 100 % RDF + Vermicompost @ 2.5 t ha-1, T7 – 75 % RDF + Vermicompost @ 2.5 t ha-1, T8 – 100 % RDF + FYM @ 5 t ha-1 + Vermicompost @ 1.25 t ha-1, T9 – 75 % RDF + FYM @ 5 t ha-1 + Vermicompost @ 1.25 t ha-1. The result revealed that the application of Application of 100 % RDF + FYM at 5 t ha-1 + Vermicompost at 1.25 t ha-1 (T8) was recorded higher values of all the growth parameters of soybean viz., plant height (42.87 cm), number of functional leaves (31.53), dry matter accumulation (24.17 g), leaf area (2.67 dm2), leaf area index (2.77 %), number of branches plant-1 (6.20), Absolute Growth Rate (AGR) for plant height (0.04 cm day-1 plant-1), Absolute Growth Rate (AGR) for dry matter (-0.55 cm day-1 plant-1) and Relative Growth Rate (RGR) for dry matter (-0.019 g g-1 day-1).
