Effect of biofertilizers on nutrient uptake and quality attributes in onion (
Allium cepa
L.)

B
iofertilizers 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 T
3
(
Azospirillum
along
with recommended dose of N, P and K) while P level was found to be maximum in T
5
(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. He has done his
