Introduction

A concentric onion storage structure (5 tier) of 250 kg (5 x 50) capacity, made of bamboo and wooden planks, was developed to be used by small and marginal farmers and the consumers in rural areas. Concentric Onion Storage structure comprises a concentric cylinder made of bamboos, a wooden base, an inlet and an outlet in each tier, four supporting legs and a top cover. The inner and outer walls are made of 25mm dia. bamboos. The base of each tier is made of 740 mm x 740mm perforated wooden planks. The height of the bottom base above the ground level as well as the height of each tier is 450mm. The cost of storage of onion in this structure has been estimated as Rs. 2.21/kg.
