Abstract
The present investigation entitled “Effect of integrated nutrient management on
different horticultural traits in onion (Allium cepa L.)” was conducted at the
Experimental Farm of Department of Vegetable Science at College of Horticulture &
Forestry, Neri, Hamirpur (H.P) during rabi season of 2021. Experiment was laid out in
Randomized Complete Block Design with three replications at spacing of 15 x 10 cm in a
plot size of 1 m x 0.75 m accommodating 50 plants per plot. The results revealed that
growth parameters viz., minimum days to marketable maturity (108.00), maximum plant
height (44.48 cm), number of leaves (9.73), leaf length (46.26 cm), average bulb weight
(82.36 g), bulb length (4.46 cm), bulb breadth (5.74 cm), bulb yield per plot (2.41 kg) and
neck thickness (1.20 cm) were recorded by treatment T7 (75 % Recommended dose of
NPK + 40 kg S/ha + Bacillus subtilis + FYM). However, quality parameters viz., total
soluble solids (12.27 ⁰B), ascorbic acid (6.86 mg/100 g) and dry matter of bulb (34.56 %)
were recorded maximum in treatment T7 (75 % Recommended dose of NPK + 40 kg S/ha
+ Bacillus subtilis + FYM). Maximum gross income of ₹ 5,46,260/ha, net income of ₹
3,86,350.73/ha and B: C ratio of 2.41 were obtained with treatment T7 (75 %
Recommended dose of NPK + 40 kg S/ha + Bacillus subtilis + FYM). This study led to
the conclusion that combination of organic manure and inorganic fertilizer along with
Bacillus subtilis provides more balance nutrition for plants which improves the vegetative
phenomenon and results in better growth, yield and quality of onion, which further
improve the soil health and mitigate the environmental pollution.
