Abstract

A field study on pecan nut (cv. Western Schley) was conducted in the experimental orchard of the Department of Fruit science, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan during the year 2008 to 2009. The study comprised of one experiment in which pecan trees under investigation were subjected to foliar spray of 0.5urea, 0.1boric acid, 0.5%, zinc sulphate, 5 ml/L supramino and their combinations. The results revealed that the foliar application of 0.5% urea, 0.1boric acid, 0.5%, zinc sulphate and 5 ml/L supramino resulted in better nut quality in comparison to control. It was found that leaf nutrient contents (N, P, K, Ca and Mg) were also recorded maximum in trees treated with 0.5urea+0.1boric acid+0.5zinc sulphate+5 ml/L supramino. Maximum leaf iron content was recorded in trees treated with 0.5urea and 5 ml/L supramino whereas, trees sprayed with 0.5urea, 0.1boric acid, 0.5zinc sulphate and 5 ml/L supramino was found to have highest leaf Zn, Mn and Cu contents.
