Effects of organic manures and inorganic fertilizers on growth and yield of wheat (Triticum aestivum L.)

Abstract

The present study was conducted on loam soil at Agronomy Farm, Mewar University, Gangrar, during the rabi season of 2021-22. Ten treatments consisting of Control, 100% recommended dose of nitrogen (RDN) + 25% N through FYM, 100% T3-100% RDN + 25% N through vermicompost, 75% RDN + 25% N through FYM, 75% RDN + 25% N through vermicompost, 50% RDN + 50% N through FYM, 50% RDN + 50% N through vermicompost 50% RDN + 50% N through vermicompost, 25% RDN + 75% N through FYM, 25% RDN + 75% N through vermicompost and 100% RDN through chemical fertilizer in Randomize Block Design with three replications. The wheat cultivar of Raj-3077 was grown in the experiment.The highest yield attribute and yield were recorded with 100% RDN + 25% N through vermicompost through compost which was statistically similar to the treatment of 100% recommended dose of nitrogen (RDN) + 25% N through FYM and significantly higher than the 100% RDN through chemical fertilizer and control. Among the different combinations of organic manures with compost of nutrients, the replacement of 100% RDN through chemical fertilizer recorded significantly higher yield attributes and yield along with higher net return and B: C ratio. The treatments with compost of nutrients recorded higher nutrient content and nutrient uptake over 100% RDN + 25% N through vermicompost with inorganic fertilizer. On the basis present study, it may be conducted that the integrated use of the organic source of nutrients can enhance the productivity of the wheat system.
