Abstract

The study was conducted at the Experimental Farm of the Faculty of Agronomy, Nong Lam University, Ho Chi Minh City. The objective of the study was to determine the effects of type and dose of potassium fertilizer on growth and yield of Phan Rang garlic variety. The two-factor experiment was arranged in a randomized complete block design with 8 treatments and 3 replicates. The factor A included 2 types of commercial potassium fertilizers (KCl, K2SO4) and the factor B was 4 different doses of potassium fertilizers (110 kg/ha, 140 kg/ha, 170 kg/ha, 200 kg/ha). The results showed that the application of 200 kg K2SO4/ha increased the plant height (51.8 cm). Bulb diameter (24.7 mm), number of cloves/bulb (12.3 cloves), bulb weight (4.83 g), percentage of dry matter (92%) and bulb yield (1.36 kg/100 pots) were highest in the garlic plants with potassium application at 200 kg/ha.
