Response and productivity of Garlic (Allium Sativum L.) by different levels of potassium fertilizer in farm soils

Abstract

In this study, six levels of K viz. 0, 100, 125, 150, 175, 200, 250 kg ha−1 were used as treatments. All the parameters, i.e., plant height, number of leaves plant−1, fresh and dry weights of leaves (g plant−1), fresh and dry weights of bulb (g plant−1), bulb diameter, and number of cloves bulb−1 significantly varied due to different doses of K application. The maximum total yield and size of garlic bulb were obtained with potassium application at 200 kg ha−1. Potassium at 200 kg ha−1 produced the highest fresh and dry weights of bulbs and leaves, diameter, moisture content, number of cloves, and yield as compared to the other treatments. The uptake of nutrients like N, P, K, S, Ca, Mg, B, and Na significantly varied due to the application of different doses of K. The highest contents and nutrient uptake of N, P, K, S, Ca, Mg, B, and Na were found with potassium application at 200 kg ha−1.
