Effect of Integrated Nutrient Management on Growth, Yield and Quality in Garlic (Allium sativum L.)

Abstract

Garlic has the charisma of a potent remedy and has held its repute as a therapeutic panacea since the dawn of civilization. So to increase its productivity and medicinal value integrated approach will be required. Allicin is the main bioactive compound, which is responsible for the medicinal value produced by garlic. It is present in the bulb in the form of allicin, which is converted to allicin when the bulb is cut or crushed. The study was conducted on the garlic variety “Kandaghat Selection”. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications comprising fourteen treatments was carried out at the Experimental farm of Horticulture Research and Training Station and KVK, Kandaghat, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during the Rabi season of 2018-19. Out of the fourteen treatments comprising of 100% recommended dose of NPK + 50 kg S/ha + 5% Jv @ 1 L/ m2 (T7) recorded significantly higher plant height, number of leaves per plant, bulb weight, bulb diameter, number of cloves per bulb, bulb yield, dry matter content of bulb and TSS. Phytomedical evaluation by HPLC showed that all bulbs from all treatments are rich in allicin content and their recorded values were higher than pharmaceutical grade.
