Abstract

A field experiment was conducted at the main experiment station vegetable farm of Achyara Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (Uttar Pradesh) during the Rabi season, 2021-22. The experiment was laid out in randomized block design (RBD) with eleven treatments replicated three times. The treatment comprises T1 (100% N), T2 (75% N + 2 Spray of nano N), T3 (50% N + 2 Spray of nano N), T4 (0% N + 2 Spray of nano N), T5 (100% N and Zn (25 kg ZnSO4/ha)), T6 (75% N + 2 Spray of nano N + Nano zinc spray), T7 (50% N + 2 Spray of nano N + Nano zinc spray), T8 (0% N + 2 Spray of nano N + Nano zinc spray), T9 (75% N + 2 Spray of Urea (2%)), T10 (75% N + 2 Spray of Urea (2%) + zinc sulphate* (2g/l) spray), T11 (Control). The variety ‛Kufri Khyati’ was used for the study. The study indicated significant differences among different treatments concerning growth and yield. The Plant emergence was not influenced by various sources of nutrients NPK and nano fertilizers as well as nitrogen and zinc. Among different treatments, a significant effect was observed on plant height at 30 and 60 DAS. Maximum plant height at 30 DAS (21.40 cm) and 60 DAS (61.00 cm) were observed under T6 treatment, where 75% N + 2 Spray of nano N + Nano zinc spray was applied. Among the different treatments, a significant effect was also observed on tuber yield ha-1 as compared to the control plot. Maximum tuber yield (322.27 q ha-1) was observed in T6 treatment (where 75% N + 2 Spray of nano N + Nano zinc spray) while minimum tuber yield was recorded with T4 treatment 0% N + 2 Spray of nano N was applied. Along with the different treatments was also observed significant effect on haulm yield ha-1 was as compared to control plots. Maximum haulm yield (177.25 q ha-1) was observed in T6 treatment (where 75% N + 2 Spray of nano N + Nano zinc spray) while minimum haulm yield was recorded in T4 treatment where 0% N + 2 Spray of nano N was applied.

Conclusion

This study's conclusion was the integration of 75% nitrogen through inorganic urea, and 2 % nano urea was found superior in the growth and yield of potatoes. A combination of inorganic and nano nitrogen in the proportion of 75% through urea + 2% nano urea, nano zinc, and NPK uptake by potato tuber and haulm was a better response of nutrients. Based on the result, it may be concluded that the influence of nano fertilizers and management (75% N through urea, 2 Sprays of nano N, and Nano zinc spray) was found to better treatment on growth and yield.
