Abstract

The present investigations were carried out at the RHR&TS, Dhaulakuan, District Sirmour of Dr. Y. S. P. University of Horticulture & Forestry, Nauni, Solan. There are also several challenges that need to be considered, including leaf surface and plant coverage, timing and frequency, chemical compatibility, environmental factors, and cost-effectiveness. This investigation was conducted on 15 year old Kinnow fruit trees, with 8 treatments as T1 Urea as 1%, T2 ZnSO4 as 0.4%, T3 2,4-D as 20 ppm, T4 Urea as 1% + ZnSO4 as 0.4%, T5 Urea as 1% + 2,4-D as 20 ppm, T6 ZnSO4 as 0.4% + 2,4-D as 20 ppm, T7 Urea as 1% + ZnSO4 as 0.4% + 2,4-D as 20 ppm and T8 Control. From the observation in maximum fruit quality of Kinnow as TSS, Juice content, Acidity, Sugars and Vitamin C was recorded with T7 treatment. In case of macro and micro leaf nutrients was also recorded with Urea, Zinc and 2,4-D combination. From the this view it may be concluded that combination of the Urea, Zinc and 2,4-D increase the fruit quality and leaf nutrients.

Conclusion

This investigation was conducted as T1 Urea as 1%, T2 ZnSO4 as 0.4%, T3 2,4-D as 20 ppm, T4 Urea as 1% + ZnSO4 as 0.4%, T5 Urea as 1% + 2,4-D as 20 ppm, T6 ZnSO4 as 0.4% + 2,4-D as 20 ppm, T7 Urea as 1% + ZnSO4 as 0.4% + 2,4-D as 20 ppm and T8 Control. From the observation in maximum fruit quality of Kinnow as TSS, Juice content, Acidity, Sugars and Vitamin C was recorded with T7 treatment. In case of macro and micro leaf nutrients was also recorded with Urea, Zinc and 2,4-D combination. From the this view it may be concluded that combination of the Urea, Zinc and 2,4-D increase the fruit quality and leaf nutrients. By following proper guidelines and recommendations, growers can effectively use foliar spray to enhance the nutritional value, shelf life, and appearance of Kinnow fruit.
