“Effect of Organic manure, Bio-fertilizer and Nano-fertilizer on Yield and Economics of different Vegetable crops and soil nutrient status”

Abstract

In the era of nanotechnology, nano-fertilizers offer sustainable and profitable remedies to modern agriculture practices while restricting the use of chemical fertilizers. Nano-fertilizers have significantly contributed towards efficient and eco-friendly approaches in crop yield productivity, nutrient penetration and soil fertility. Owing to the remarkable physicochemical properties and integrated nutrient management system, the effectiveness of organic manures, Nano Nitrogen and Nano Di-ammonium Phosphate (DAP) in respect to the untreated field environment were compared and studied on two important crops viz. cauliflower and tomato. Standard field conditions were optimised and on-farm trials in 40 different farms of sandy loam soil were conducted by IFFCO and KVK in village Khatawali, Rewari district of Haryana, Rabi season 2020-21 and 2021-22. The results of this study have clearly demonstrated the synergetic potential of organic manure, bio-fertilizer and nano-fertilizers with a rise of 12.2–15.4% yield in cauliflower and 12.6–14.9% yield in tomato. While the net return was increased by 25.8–31.7% in Cauliflower and 21.4–25.0% in Tomato as compared to T1 and T2. Extensive analysis is made on growth parameters such as the height of the plants, number of primary branches, average fruit weight that escalated the productivity of crops besides the forecast of beneficially effected economics i.e. Benefit Cost (B: C) ratio. Average data of post harvested soil indicated the enhanced organic carbon content, NPK and lowered C:N ratio that ensures on soil improvement. Hence, these findings strongly highlight the synergetic efficacy of Nano Nitrogen and Nano DAP on crop quality and net productivity.
