GROWTH, YIELD AND QUALITY OF ONION AS INFLUENCED BY INTEGRATED NUTRIENT MANAGEMENT
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 51
Abstract
A Field experiment was conducted to access the effect of different combinations of bio-fertilizer along with inorganic fertilizers and organic manures on growth, yield and quality of onion during kharif season. The experiments consisted of fifteen treatments of bio-fertilizers and organic manures with or without chemical fertilizers. The results revealed that the number of leaves per plant, plant height and leaf area was maximum with the application of Azotobacter along with recommended dose of fertilizers. Minimum neck thickness was recorded in treatment where Azospirillium was applied along with recommended dose of fertilizers. Likewise, the Azospirilum produced the maximum bulb weight 138.3g and total yield 299.6 q/ha when it was applied with recommended dose of fertilizer. But bulb diameter were maximum of Azotobacter along with recommended dose of fertilizers (T1) followed by Azospirillium along with recommended dose of fertilizers. Maximum TSS (13.90 brix) and ascorbic acid (14.1 mg/100g fresh weight) was found also Azospirilum with recommended dose of fertilizer. It is concluded that Azotobacter along with 100% NPK improves vegetative growth, while Azospirillium along with 100% NPK improves yield and yield attributes of onion as far as the sustainability and environmental consideration are concerned.
