Response of spinach (Beta vulgaris var. bengalensis) to integrated nutrientmanagement practices under protected condition

Abstract

An experiment was conducted at Hi-tech Horticulture Unit, MARS, Saidapur Farm, UAS, Dharwad duringsummer, 2021 to assess the effect of integrated nutrient management practices on growth and yield of spinach underprotected condition. The treatments comprised of graded levels of recommended dose of fertilizers (100 %, 75 % and 50 %RDF) and graded levels of recommended dose of nitrogen (100 %, 50 % and 25 % RDN) applied through farm yard manure(FYM), vermicompost, neemcake (NC) and biofertilizers (Azotobacter and PSB). The results revealed that application of50 % RDF + 50 % RDN applied through FYM and NC (2:1) + Azotobacter and PSB was found better for higher plantheight, number of leaves and total yield (21.42 t/ha) and 75 % RDF + 25 % RDN through vermicompost and neem cake (2:1)+ Azotobacter + PSB gave highest leaf area (152.27 cm2).
