Effect of Nano Fertilizer on Growth, Yield and Quality of Broccoli (Brassica oleracea var. italica)

The experiment was conducted in the Horticulture Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higgin bottom, University of Agriculture, Technology and Sciences, Prayagraj (UP) during October 2021 to february 2022. The experiment was laid out in randomized block design (R.B.D.) with 10 treatments with 3 replications. From the observations it was found that T2 (Soil application of 50% recommended dose of fertilizers as conventional fertilizer + 50% recommended dose of nano N as foliar application nano P&K as soil application) had the best impact on the growth and yield and quality parameters like plant height 65.27 cm, number of leaves per plant 27.14, leaf length 55cm, leaf width 21.83cm, leaf area at harvesting stage 725.00 cm2, days to head initiation 45.42 days, days to harvest 55.67, head diameter 21.16cm, head weight 461.47 gm, head yield per plot 2.77 Kg, head yield per hectare16.95t, TSS 9.76 Brix. The highest cost benefit ratio 3.55 was also observed in T2.
