Effect of Integrated Nutrient Management on Nutritional Quality, Uptake and Yield of Wheat in Vertisol

Abstract

The present investigation was carried out during rabi season of 2021-22. at Agricultural Botany research farm, College of Agriculture, Nagpur. The treatment tested were T1-GM*+100 % RDF, T2-Ghanajivamrut 5 t ha-1 at incorporation of GM* + 50 % RD of NP through inorganic fertilizers + Jivamrut + Azophos, T3- Vermicompost 5 t ha-1 at incorporation of GM* + 50 % RD of NP through inorganic fertilizers + Jivamrut + Azophos, T4-Neem cake 2 t ha-1 at incorporation of GM* + 50 % RD of NP through inorganic fertilizers + Jivamrut + Azophos, T5-Ghanajivamrut 5 t ha-1 at incorporation of GM*, T6- Vermicompost 5 t ha-1 at incorporation of GM* + Jivamrut + Azophos and T7- Neem cake 2 t ha-1 at incorporation of GM* + Jivamrut + Azophos. The result showed that the grain yield of wheat varied from 21.03 to 31.36 q ha-1 and straw yield of wheat from 27.45 to 41.10 q ha-1 It was noted the N uptake varied from 48.40 to 78.84 kg ha-1, P from 10.38 to 20.52 kg ha-1 and K from 48.80 to 77.82 kg ha-1. The protein content in wheat varied from 10.93 to 11.81 per cent, carbohydrate, crude fibre and calcium in wheat grain varied from 70.82 to 71.92, 2.56 to 2.63 and 0.40 to 0.48 pe cent, respectively. The methionine, cysteine and lysine content in wheat varied from 1.36 to 1.45, 1.41 to 1.47 and 2.42 to 2.53 g / 16 g N. The application of Vermicompost @ 5 t ha-1 at incorporation of GM* + 50 % RD of NP through inorganic fertilizers + Jivamrut + Azophos was found most suitable treatment in respect of crop yield, uptake of nutrient and quality of wheat.
