Abstract
Garlic (Allium sativum L.) is one of the most important and widely consumed bulbous spice crop belong to the family Alliaceae. It is cultivated throughout India for its bulb which forms an integral part of Indian culinary preparation. The bulb can be consumed as spice or condiment . Garlic bulb contains colourless, odourless, water soluble amino acid called allin. On crushing the garlic, the enzyme allinase breaks down allin to produce allicin in which the principle ingredient is the odoriferous diallyl disulphide.
The study was conducted to find out the best integrated nutrient approach with organic manures, biofertilizers along with different levels of N, P, K on growth, yield and quality attributes of garlic cv. AAS-2, at the Department of Plantation, Spices, Medicinal and Aromatic Crops, Kittur Rani Channamma College of Horticulture, Arabhavi, Karnataka during 2014-2015.
The experiment comprised of 11 treatments replicated thrice adopting RCBD design. Among the treatments, application of 75 % RD N + RD PK + RD FYM (25 t/ha) + Azatobacter beijerinckii (325g /ha)+ PSB (325g /ha)+ Trichoderma viride (5 kg/ha) performed better with respect to growth parameters viz. plant height (52.83 cm), number of leaves per plant (7.53) and yield attributes like fresh and dry weight (10.58 t/ha), bulb diameter (27.04 mm), number of cloves per bulb (20.77) and bulb yield (10.39 t /ha) with maximum nutrient uptake under irrigated ecosystem of Northern dry zone of Karnataka conditions. However application of Vermicompost (2.5 t/ha) +Azospirullum brasilense (325 g /ha)+ PSB (325 g/ha) +Trichoderma viride (5 kg/ha) was found to be superior to other treatments in benefit cost ratio (3.3:1) and quality (0.043 % Sulphur ) of garlic and it proved that application of application of bio-fertilizers along with organic manures reduces 25 per cent of recommended dose of fertilizers.The next best treatment was 50 % N +RD PK + RD FYM (25 t/ha) + Azospirullum brasilense (325 g /ha)+ PSB (325 g /ha) + Trichoderma viride (5 kg/ha) for commercial cultivation of garlic under irrigated ecosystem of Northern dry zone of Karnataka.
