Effect of potassium and sulphur on soil properties and growth and yield of onion (Allium Cepa l.) cv. Nasik red

Jefferson Brandon Mukhim, Narendra Swaroop, Arun Alfred David, Tarence Thomas

The experimental layout was done in a randomised block design (RBD) with nine treatments replicated three times. Treatments were assigned randomly which consisted of three levels of potassium i.e. 0, 25 and 50 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 (76 cm), bulb length (5.8 cm), bulb diameter (7.8 cm), total bulb yield *(13.55 t ha-1) showed significantly better results with the treatment T8 (potassium at 100 kg ha-1 and sulphur at 100 kg ha-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 decrease on 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 T8 i.e. potassium at 100 kg ha-1 and sulphur at 100 kg ha-1 with a cost benefit ratio of 1:4.88 was found to be the most beneficial and significantly improved the growth parameters and bulb yield of onion grown under Prayagraj Agro climatic conditions.
