Yield and nutrient uptake as influenced by the integrated nutrient management in foxtail millet

Abstract

A field experiment was conducted at Main Agricultural Research Station, Raichur, during kharif 2018-19 to study the integrated nutrient management on Foxtail millet (Setaria italic L.) in black soil. The experiment was laid out with eleven treatments replicated three times in randomized block design. Among all the treatments, application of RDF +2.5 t ha-1 Vermicompost + Bio-fertilizer + Foliar spray of 19:19:19 at 15, 30 and 45 DAS significantly recorded grain yield and straw yield were significantly recorded (2414 kg ha-1 and 6034 kg ha-1) as compared to absolute control and RDF. The treatment also recorded higher higher nitrogen, phosphorus and potassium uptake (36.9, 9.7 and 18.1 kg ha-1 in grain, 56.7, 18.1 and 79.1 kg ha-1 in straw, respectively). It is concluded that the application of RDF + 2.5 t ha-1 Vermicompost + Bio-fertilizer) + Foliar Spray of 19:19:19 at 15, 30 and 45 DAS is the best treatment in rainfed condition to achieve higher yield, nutrient content and nutrient uptake as compared to RDF and absolute control.
