Effect of Iron Application Methods on Nutrients Availability in Soil, Growth and Yield of Mung Bean

Abstract

Thesis Title: “Effect of Iron Application Methods on Nutrients Availability in Soil, Growth and Yield of Mung bean” A field experiment was conducted to assess effect of Iron Application Methods on Nutrient Availability in Soil, Growth and Yield of Mung bean” was conducted at the Crop Research Centre (CRC) of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut (U.P.) in the Kharif season of 2022. In eight treatments consistent different application of Iron viz., control, recommended RDF, RDF + seed priming with 0.4% Ferrous Sulphate, RDF + Ferrous Sulphate @ 10 kg ha-1, RDF + Foliar spray of Ferrous Sulphate @ 0.5% at pre flowering stage, RDF + seed priming with 0.4% Ferrous Sulphate + Ferrous Sulphate @ 10 kg ha-1, RDF + seed priming with 0.4% Ferrous Sulphate + Foliar spray of Ferrous Sulphate @ 0.5% at pre flowering stage and RDF + seed priming with 0.4% Ferrous Sulphate + Foliar spray of Ferrous Sulphate @ 0.5% at pre flowering stage + Ferrous Sulphate @ 10 kg ha-1. The results revealed that the application of iron as basal, foliar and seed priming significantly influence the growth, nutrient availability of soil, and yield of mung bean as compared to the control during the experimentation. Significant improvement in growth parameters viz., plant population, plant height, number of branches plant-1, number of physiologically active leaves plant-1, dry matter accumulation (g plant-1) and number of nodules plant-1, protein content, test weight, nutrient content and grain yield was recorded with the application of recommended RDF + seed priming with 0.4% Ferrous Sulphate + Foliar spray of Ferrous Sulphate @ 0.5% at pre flowering stage + Ferrous Sulphate @ 10 kg ha-1, which established its superiority over the rest of the treatments. The application of RDF + seed priming with 0.4% Ferrous Sulphate + Foliar spray of Ferrous Sulphate @ 0.5% at pre flowering stage + Ferrous Sulphate @ 10 kg ha-1 resulted in the higher protein yield (281.18 kg ha-1). The total nitrogen, phosphorus, potassium and iron uptake (81.98, 14.26, 46.77 (kg ha-1) and 417.24 (g ha-1) respectively by mung bean crop was recorded is also highest with the application of the same treatment. Significant increase in microbial population has also recorded due to the same treatment. Thus the application of RDF + seed priming with 0.4% Ferrous Sulphate + Foliar spray of Ferrous Sulphate @ 0.5% at pre flowering stage + Ferrous Sulphate @ 10 kg ha-1 was found better for sustainability of mung bean.
