Effect of Traditional Fertilizer, Nano Fertilizer and Micronutrient on Growth, Yield and Quality of Chilli (Capsicum annum L.)

The present investigation was carried out at the Horticulture Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh during Kharif season 2022-23 on variety TMPH-409. The experiment was laid out in Randomized block design with 11 treatments and 3 replications with different combination in nano fertilizers. Among the treatments tested, T2 (75% N (through traditional method), 100% PK, 100% ZnSO4, and 25% N as foliar spray through Nano urea) showed the most favorable results in terms of plant height (99.69 cm at 90 DAT), number of primary branches (8.18 branches at 90 DAT), and early flowering (38.16 DAT) and maturing (72.14 DAT). T2 also demonstrated superior performance in terms of fruit weight (2.72 g), length of fruit (7.52 cm), fruit girth (2.76), number of fruits per plant (260.10 fruits), and yield per plant (173.07 g/plant) and fruit yield per hectare (23.37 q/ha).
