Evaluation of Integrated Nutrient Management Practices on Growth and Yield of Wheat (Triticum aestivum L.) under Northeastern Part of Rajasthan, India

Abstract

An experiment was conducted during rabi season of 2023-24 to study the effect of organic and natural farming nutrient sources on growth and productivity of wheat. The experiment was laid out in randomized complete block design with 10 treatments and thrice in replication viz., 100% RDN through chemical fertilizer, 75% RDN + 25% N through neem cake, 75% RDN + 25% N through neem cake + NP consortium, 75% RDN + 25% N through neem cake + Jeevamrut (500 lit/ha), 50% RDN + 50% N through neem cake, 50% RDN +50% N through neem cake + NP consortium, 50% RDN + 50% N through neem cake + Jeevamrut (500 lit/ha), 50% RDN + 50% N through neem cake + NP consortium + Jeevamrut (500 lit/ha), 50% RDN + NP consortium + jeevamrut (500 lit/ha) and NP consortium + Jeevamrut (500 lit/ha). The results showed that application of 75% RDN + 25% N through neem cake + Jeevamrut (500 lit/ha) recorded significantly higher growth attributes, yield attributes and yield, and economics. The maximum grain and straw yield (6280 and 8854 kg/ha) was registered by application of 75% RDN + 25% N through neem cake + Jeevamrut (500 lit/ha) which was statistically at par with application of application of 100% RDN through chemical fertilizer, 75% RDN + 25% N through neem cake + NP consortium and 75% RDN + 25% N through neem cake as compared to NP consortium + Jeevamrut (500 lit/ha) (3885 and 3775 kg/ha) and 50% RDN + 50% N through neem cake + NP consortium + Jeevamrut (500 lit/ha), 50% RDN + 50% N through neem cake + Jeevamrut (500 lit/ha) and 50% RDN +50% N through neem cake + NP consortium.
