The present study was carried out during winter (rabi) seasons of 2020-21 and 2021-22 at Sri Karan Narendra College of Agriculture, Jobner, Jaipur, Rajasthan to evaluate the impact of nitrogen management (organic and inorganic sources), biofertilizer and foliar spraying of nano-urea on yield, quality and storage attributes of garlic (Allium sativum L.). The experiment consisted of 3 levels of organic and inorganic fertilization, 2 levels of bio-fertilizers in main plot, and 4 levels of nano-urea arranged in split plot design (SPD) in sub plot. The results showed that yield, quality and storage attributes of garlic, viz. number of cloves/bulb (16.46%), clove length and girth, average weight of clove (1.56 gm), nitrogen, phosphorus and potassium content in bulb (1.10, 0.31 and 0.51%), physiological loss in weight, shelf-life of bulbs and rooting percentage of bulbs were significantly enhanced by 100% recommended dose of nitrogen through inorganic fertilizers and bio-fertilizer in main plot. In sub plot, the foliar spray of nano-urea @75 ml/ha recorded highest number of cloves per bulb (16.26%), clove length and girth (2.86 and 1.07 cm), average weight of clove (1.55 gm), nitrogen, phosphorus and potassium content in bulb (1.09, 0.31 and 0.51%), shelf-life of bulbs and rooting percentage of bulbs. Therefore, this study concluded that the nitrogen management and nano-urea in garlic crop gives better yield, quality and storage attributes, and can be opted in semi-arid climatic conditions.
