Effect of Plant Biostimulants on Growth, Chlorophyll Content, Flower Drop and Fruit Set of Pomegranate Cv. Kandhari Kabuli

The experiment was laid out in the pomegranate experimental block of the Department of Fruit Science, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh. The experiment consisted of 19 treatments with three replications. The pomegranate trees under investigation were subjected to different concentrations of biostimulants viz. Vipul (TRIA) (5 ml/l, 10 ml/l, 15 ml/l), Spic cytozyme (1 ml/l, 2 ml/l, 4 ml/l), Homobrassinolides (Godrej Double) (0.5 ml/l, 1 ml/l, 1.5 ml/l), Biozyme Crop Plus (1 ml/l, 2 ml/l, 3 ml/l) and Vipul + Homobrassinolides (0.5 + 5 ml/l, 1 + 5 ml/l, 1.5 + 5 ml/l, 5 + 0.5 ml/l, 5 + 1 ml/l, 5 + 1.5 ml/l). The results revealed that the highest tree growth was recorded in trees treated with Spic cytozyme at 4 ml/l. The highest total chlorophyll content was observed with the application of Vipul 15ml/l, whereas the highest fruit set and minimum flower drop was recorded with the application of Vipul + Homobrassinolides (1.5 + 5 ml/l).

An experiment was laid out on pomegranate cv.Kandhari Kabuli with varied concentrations of biostimulants.

Results revealed that the highest tree growth was recorded in trees treated with Spic cytozyme @ 4 ml/l, where as highest total chlorophyll content was observed with Vipul @15ml/l, and highest fruit set and minimum flower drop was recorded with the application of Vipul and Homobrassinolides @1.5 and 5 ml/l respectively.
