Growth, Yield and Quality of Garilic (Allium sativum L.) Influenced by the Application of Sulphur and Salicylic Acid

Abstract

A research experiment was conducted at vegetable research Complex, Maharajpur, Department of Horticulture, College of Agriculture, JNKVV Jabalpur. The experiment was done to study the effect of sulphur and salicylic acid on Yamuna safed -2 variety of Garlic. The growth, yield, and quality of garlic can be influenced by various factors, including nutrient availability and plant growth regulators like salicylic acid. Sulphur is an essential nutrient for plant growth and plays a crucial role in the development of garlic plants. The experiment was conducted in Randomized Block Design with combination of different concentrations of sulphur (0 kg/ha, 30 kg/ha and 45 Kg/ha) and salicylic acid (60 ppm and 120 ppm). Growth parameters like plant height, number of leaves and pseudostem diameter were found maximum in treatment T-9 (sulphur 45kg/ha and SA 120ppm). Yield parameters like average bulb weight (22.27 gm), Polar diameter (4.41 cm) and Equatorial diameter (3.79 cm) average weight of 10 cloves (9.10 gm), Total soluble solids and Pyruvic acid were also maximum in T-9 (Sulphur 45kg/ha and SA 120 ppm) (42.30 oBrix and 66.09 µmol/gm respectively). From the above findings it can be concluded that for garlic plant the best doses for salicylic acid and sulphur were found to be 120 ppm and 45 kg/ha. Also with graded levels of salicylic acid and sulphur various parameters increased effecttively.
