Effect of Zinc and Boron on the growth and yield of gulabi variety of Garlic (Allium sativum L.) under agro-climatic condition of Peshawar, K. P

A field experiment was conducted to determine the effect of micronutrients on growth and yield of gulabi variety of garlic (Allium sativum L.) during 2014-2016 at Institute of Biotechnology and Genetic Engineering (IBGE) Agriculture University Peshawar. Seeds of garlic cultivar Lehson Gulabi were collected from local farmers. Zinc was applied in the form of zinc sulphate while boron was applied in the form of boric acid. Three levels of zinc 3ppm, 4ppm and 5ppm and three levels of boron 0.50ppm, 0.75ppm and 1ppm with different combinations of Zinc + Boron 3+0.50ppm, 4+0.75ppm, 5+1ppm were applied. The experiment was laid out under RCBD (Randomized Complete Block Design) having 10 treatments and three replications. Maximum number of leaves (8.45) and maximum dry weight of leaves (13.06g) was shown by T3 (Zinc 5ppm@ 0.0123gha-1). Maximum weight of bulb per plant (57.03g) and average yield hectare−1 (0.83) was shown by T7 (3+0.50ppm @ 0.029g + 0.0074gha-1. Maximum plant height (58.66cm) and maximum phenolic contents (1.77mg/g) were found in T5 (Boron 0.075ppm @0.042gha-1).
