Impact of Biofertilizers with Levels of NPK on Nutrient Uptake and Yield of Onion (Allium cepa L.) cv. Bellary Red in Kharif Season under Irrigated Situation in Central Dry Zone of Karnataka

摘要

A study on the impact of bio-fertilizers with levels of NPK on nutrient uptake and yield of onion cv. Bellary Red was carried out in medium black soils during kharif season under irrigated situation at the Agricultural Research Station, Hiriyur located in Central Dry Zone of Karnataka with 12 treatments replicated three times in randomized block design. The results revealed that the plants provided with Azospirilum + 100 per cent N + PK (125 : 50 : 125 NPK kg /ha) showed maximum uptake of N, P and K(157.88 : 73.56 : 70.46 NPK kg /ha) and highest bulb yield (250.29 q /ha) under irrigated condution during kharif season.
