Question

Effect of integrated nutrient management on growth and yield parameters of maize (zea mays l.) as well as soil physico-chemical properties

Answer 1

Abstract

A field experiment was conducted during the winter season of 2013 at a main research field of the School of Agriculture Lovely Professional University, Phagwara, Punjab (India) to study the influence of integrated nutrient management on growth and yield parameters of maize (Zea mays L.) as well as soil physico-chemical properties. The growth parameters (plant height and leaf area) were found to be highest under INM (Integrated Nutrient Management) of poultry manure (PM) or farm yard manure (FYM)and recommended dose of fertilizers (RDF) which are statistically on par but comparatively higher than T₁ (100% RDF). The yield parameters (number of grains per cob, cobs weight per plant, Test weight and stover yield) were significantly higher under INM compared to T₁ (100% RDF). Furthermore, post harvest soil physico-chemical properties (organic carbon and available nitrogen) were significantly improved under T₃ (5t PM + 50% RDF), whereas soil available phosphorus was recorded maximum under T₅ (5t PM + 100% RDF) compared to control and rest of the treatments combination. Therefore, the integration of 50% RDF along with either 5 t/ha FYM or PM or both resulted in maximum maize productivity on par compared with sole used of 100% RDF.
