Studies on the influence of bio-fertilizers with levels of NPK on the yield and processing qualities of onion (Allium cepa L.) cv. Bellary Red in rabi season under irrigated situation.

摘要

Studies on the influence of bio-fertilizers with levels of NPK on the yield and processing quality parameters of onion cv. Bellary Red were carried out during rabi seasons under irrigated conditions at the Agricultural Research Station, Hiriyur in Central Dry Zone of Karnataka. Effects of 12 treatments were tested on onion crop in medium black soil under field condition. The results revealed that the plants provided with Azospirillum+100% N+PK (Azospirillum+125:50:125 NPK kg/ha) produced maximum bulb weight, bulb yield and dry matter yield of the bulbs with better storage qualities under irrigated conditions during rabi seasons. This level can be adopted for Bellary Red onion under irrigated condition during rabi seasons in Central Dry Zone of Karnataka.
