Effect of Phosphorus Fertilization and Psb on Garlic Quality under Organic Farming System

Abstract

The present investigation was undertaken in complete randomized design with three replicates during winter season of 2017/2018 to study the effect of phosphorus fertilization (50, 75 and 100 % from recommended dose), Phosphate Solublizing Bacteria (PSB) and chicken manure on growth criteria , chemical traits, bulb quality and yield of garlic plants. The findings showed that growth criteria such as plant height, No. of leaves, fresh and dry weight of whole plant and its leaves, neck and bulb, yield and its components (number of clovers/bulb, bulb diameter, neck diameter, average cloves and bulb as well as total Mg/fed), chemical content (N, P and K %) and quality parameters (TSS%, total carbohydrates, crude fiber, vitamin C, dry matter, volatile oil and allicin) as well as availability of N, P and K recorded the highest values with plant treated with 75% P fertilization+ PSB +Chicken manure.
