A field experiment was conducted to study the effect of different levels of doses of potassium and sulphur on the soil properties and also on the growth and yield of onion (Allium cepa L.) at the Research Farm of Soil Science, SHUATS, Allahabad, India, during the winter season of 2017-18. Experimental layout was done in a Randomised Block Design (RBD) with 9 treatments replicated 3 times. Treatments were assigned randomly which consisted of three levels of potassium i.e. 0, 50 and 100 kg ha-1 and three levels of sulphur i.e. 0, 15, 30 kg ha-1. The results indicated that the maximum average plant height (60.60cm), bulb length (6.1cm), bulb diameter (8.7cm), total bulb yield (13.55 tons ha-1) showed significantly better results with the treatment T2 (potassium at 100 kg ha-1 and sulphur at 30 kg -1). The same treatment also showed better results in the physical properties of the post-harvest quality of the soil like increase in % Pore Space, decrease in bulk and particle density of the soil and also showed a gradual decreaseon the chemical properties of the soil like decrease in pH, OC % and N, P, K, S values in the soil after harvest. Hence the results revealed that the treatment combination T2 i.e. potassium at 100 kg ha-1 and sulphur at 30 kg ha -1 was found to be the most beneficial and significantly improved the growth parameters and bulb yield of onion grown under Allahabad agro-climatic conditions.
