Effect of Nano Zeolite, Nano Micronutrients and Biocapsules on Plant Growth, Head Yield and Quality of Broccoli (Brassica oleracea var Italica)

The present investigation was conducted at the Vegetable Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology & Sciences (SHUATS), Prayagraj (U.P.), during the Rabi season of the year 2020–21. The experiment was laid out in a randomised block design with three replications and 15 treatments. T15 N P K (RDF) + Nanozeolite 50 ppm (Soil drenching)+ Biocapsule 500 ppm+ folia application of ZnO and FeO nano particles & T13 N P K (RDF) + Biocapsule 500 ppm (soil drenching) + foliar application of ZnO and FeOnano particles was found to be the best in Plant height, leaf area, and no of leaves. Again In terms of yield parameters, the treatment T15 N P K (RDF) + Nanozeolite 50 ppm (Soil drenching) + Biocapsule 500 ppm+ folia application of ZnO and FeO nano particles performed best in Head diameter (cm), Marketable Head Yield/plot (kg), Marketable Head Yield/hectare (q/ha), Harvest Index (%) (18.68 cm, 3.15 kg, 212.86 qh, 90.65%).
