Abstract
A field experiment entitled “Effect of foliar spray of boron and zinc on growth and development of Jamun (Syzygium cumini L. Skeels) cv. Goma Priyanka” was conducted during the year 2021-22, at the Instructional Farm, Department of Fruit Science, College of Horticulture and Forestry, Jhalawar. The experiment consisted of 16 treatments laid out in Randomized Block Design with three replications.
Among different treatments, application of T15 (Borax @ 0.50% + ZnSO4 @ 0.50%) to individual plant was found significantly superior over other treatments with respect to growth and development parameters such as per cent increase in rootstock girth (9.73%), scion girth (9.31%), plant height (39.97%), number of leaves/shoot (26.19%), number of shoots/branch (33.61%), petiole length (27.89%), length of internodes (13.55%), leaf length (29.48%), leaf width (12.54%), leaf area (45.73%), canopy volume (8.13%), canopy spread North-South (15.58%), canopy spread East - West (7.06%), relative water content (15.53%) and chlorophyll content (1.78%).
From the experiment it may be summarized that T15 (Borax @ 0.50% + ZnSO4 @ 0.50%) proved superiority over all individual as well as treatments in combination in improving growth and development parameters of jamun plant. However, it requires further study for confirmation of results.
