Abstract
Biofertilizers improve the nutrient uptake and quality attributes of onion by reducing the inorganic fertilizers dose and improving the farmer�s income. The study was conducted at Vegetable Research Farm, Punjab Agricultural University, Ludhiana. In an experiment, fifteen treatments comprised of various combinations of biofertilizers, organic manures and chemical fertilizers were compared. Biofertilizers improve the nutrient status of the soil because Azotobacter and Azospirillum provide nitrogen to plant and soil by fixation process. The results revealed that N and K level in soil at time of harvesting was maximum in T3 (Azospirillum along with recommended dose of N, P and K) while P level was found to be maximum in T5 (PSB along with recommended dose of N, P and K). Maximum TSS, Ascorbic acid and dry matter was attained with Azospirillum along with recommended dose of N, P and K followed by Azospirillum along with 75 % dose of N and full dose of P and K and it was significantly superior than control treatment. It may be concluded that Azospirillum either along with RDF or with 75 % dose of N suggested for sustainable production of onion.Biography
Dilpreet Talwar is currently a student of Ph.D program in which he is specializing in Vegetable Science at Punjab Agricultural University, Ludhiana.
