EFFECT OF VARIOUS LEVELS OF POTASSIUM AND SULPHUR ON YIELD AND THEIR UPTAKE IN GARLIC (ALLIUM SATIVUM L) UNDER WESTERN MAHARASHTRA CONDITIONSA.R. Wakhare, V. Sankar, S.A. Hiray and D.T. Desai
The field experiment was carried out at the Directorate of Onion and Garlic Research (DOGR), Rajgurunagar, Pune (Maharashtra), during rabi season of two consecutive years (2011-2012 and 2012-2013). The main objective of this experiment was to standardize the optimum level of potassium and sulphur for improving growth and yield of garlic. The experiment consisted four levels of potassium (0, 50, 75 and 100 kg ha-1) and four levels of sulphur (0, 20, 40 and 60 kg ha-1) and their combinations were laid out in factorial randomized block design with three replications. Results of a field experiment revealed that yield and dry matter of garlic increased significantly with increasing doses of potassium and sulphur. Significant positive effect of K and S on total yield (87.94 and 81.80 q ha-1) and marketable yield (85.11 and 78.60 q ha-1) were observed with 100 kg potassium and 60 kg sulphur ha-1 respectively. The uptake of K increased with increasing dose of K and S from 78.09 and 55.62 kg ha-1 with the addition of 100 kg K20 ha-1 and 60 kg S ha-1 respectively. The uptake of sulphur increased from 25.73 and 21.93 kg ha-1 with the addition 100 kg K20 ha-1 and 60 kg S ha-1 respectively.
