Yield and economics of direct seeded rice (Oryza sativa L.) as influenced by the zinc nutrition

Abstract

The field study was conducted to evaluate the “Response of direct seeded rice (Oryza sativa L.) to zinc nutrition in sub-montane zone of Maharashtra during kharif 2021. The field experiment was laid out in randomized block design with three replications and eleven treatments replicated thrice. The growth, yield and yield attributing characters of direct seeded rice recorded significantly highest with the application of RDF (100:50:50 kg NPK ha-1 +Vermicompost @ 2.5 t ha-1) + soil application of ZnSO4 @ 20 kg ha-1 + foliar application of 0.2% EDTA Zn. Soil application of ZnSO4 @ 20 kg ha-1 + foliar application 0.2% EDTA Zn + RDF and Vermicompost recorded maximum gross returns, net monetary returns and benefit cost ratio.
