Response of Mixed Nano Micronutrients on Growth and Quality of French Bean

Micronutrients are essential for the enzymatic activity of plants, which affects fruit quality and growth. The study was conducted in the Rabi season of 2021 at SHUATS, Prayagraj. The purpose of the study was to investigate how the French bean variety "Arka Komal" was affected by mixed nano micronutrients in terms of growth and quality. The experiment was set up using a FRBD one factor being application of mixed nano micronutrients and other being application of nano fertilizers. The mixed nano micronutrients given were M0-control; M1- 0.2ml/ L of nano mix micronutrient/L of water as foliar application; M2- 0.4ml/L of nano mix micronutrient/ L of water as foliar application; M3 -0.6ml/ L of nano mix micronutrient/L of water as foliar application. The nano-fertilizers treatment given were F0– Control (without fertilizer); F1- 100% RDF as traditional fertilizer; F2-5ml/ L each of Nano NPK/ L of water as foliar application; F3- 4ml/L each of Nano NPK/ L of water as foliar application; F4- 3ml/L each of Nano NPK/ L of water as foliar application. 50% traditional fertilizers were applied in all treatments excluding control. From above experimental findings it was concluded that treatment M3 performed best for growth parameters like plant height; leaf area studied in French bean. M3 performed best for quality parameters like TSS, ascorbic acid content.
