A field study was conducted to evaluate the impact of nano-fertilizer and nano-mixed micronutrients on the growth, and flowering of tomato (Lycopersicon esculentum Mill.) cv. Heemsohna under open field conditions at the Horticulture Research Farm, Department of Horticulture, Sam Higginbottom University of Agricultural, Technology and Science, Prayagraj, over two consecutive years, 2021-22 and 2022-23. The aim was to identify the most effective treatment using nano NPK and nano-mixed micronutrients for optimizing tomato growth and flowering. The experiment employed a factorial randomized block design with two factors and three replications. The different applications of nano NPK and nano-mixed micronutrients significantly influenced the growth, flowering, of tomato cultivation. Specifically, the treatment involving 4 ml of Nano NPK and 6 ml of nano-mixed micronutrients per litter of water as foliar applications (FA) demonstrated superior performance across various parameters including plant height, number of branches per plant, number of leaves per plant, leaf area, internode length, number of flowers per plant, In summary, the study highlights the positive impact of nano-fertilizers and nano-mixed micronutrients on tomato growth and flowering. The identified superior treatment combinations can serve as practical recommendations for enhancing tomato production while ensuring economic viability under similar growing conditions.
