Abstract: The present investigations entitled “Effect of foliar application of 2, 4-D, urea and zinc sulphate on fruit drop, yield and fruit quality of Kinnow mandarin” was carried out in the Horticultural Regional Research Station, Dhaulakuan, Sirmour, of Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan during the year 2011-2012. The experiment was laid down in Randomized Block Design with 8 treatments and 3 replications. The study comprises of one experiment in which Kinnow trees under investigation were subjected to treatments of 1 per cent urea, 0.4 per cent zinc sulphate, 20ppm 2, 4-D and their combination. The results revealed that the foliar application of 1 per cent urea, 0.4 per cent zinc sulphate and 2, 4-D- 20ppm combination resulted in highest tree growth in comparison to control. It was found that leaf nutrient contents (N, P, K, Ca, Mg and Cu) were also recorded maximum in trees treated with 1 per cent urea 0.4 per cent zinc sulphate and 2, 4-D- 20ppm combination treatment. Maximum leaf iron content was recorded in trees treated with 1 per cent urea and 0.4 per cent zinc sulphate combination. Whereas, trees sprayed with 0.4 per cent zinc sulphate and 2, 4-D- 20ppm gave highest leaf Zn content and maximum leaf Mn found with treatment1 per cent urea and 2, 4-D- 20ppm combination.
