Effect of Foliar Application of 2, 4-D, Urea, Zinc Sulphate, Bavistin and Combinations on Nutrient Content of Kinnow Mandarin

The present experiment entitled was conducted at CCS Haryana Agricultural University, Hisar during 2019-20 and 2020-21 to find out the best concentration of foliar application of growth regulators, nutrients and fungicides in improvement of nutrient status of leaves.There were eighteen treatments, , 2,4-D at 10 and 15 ppm, GA at15 and20 ppm, Urea at 1 and 1.5%, Zinc Sulphate at 0.5and 0.75%, Bavistin i.e.3 1000 ppm and their combinations on 9-year-old Kinnow.The foliar spray was done two times ., first in the last week of May and second in the i.e last week of July.After foliar spray, maximum leaf N (2.51%), Zn (14.97 ppm) and S content (0.22%) was with foliar spray of 2,4-D 15 ppm + Urea 1.5% + Zinc Sulphate 0.75% + Bavistin 1000 ppm, however leaf P, K and Fe were not significantly affected by foliar application of plant growth regulators, nutrients and fungicides.
