Effect of Crop Geometry on Growth and Yield of Kharif Onion

The experiment was conducted to check the effect of crop geometry on growth and yield of kharif onion. The experiment was laid out in randomized complete block design with three treatments viz., T₁=10×7.5cm, T₂=10×10cm and T₃=15×10cm replicated three times. Results showed that transplanting of onion in 15×10cm resulted in significantly higher plant height (30.87 cm), number of leaves per plant (12.20), bulb diameter (polar-5.20 cm and equatorial-5.74 cm) and average bulb weight (83.90g) as compared to 10×7.5 cm but statistically at par with 10×10cm crop geometry. Highest bulb yield was recorded in 10×10cm (307.64q/ha) with per cent increase of was 23.41 and 0.57 in comparison to 10×7.5 (247.85q/ha) and 15×10cm (305.89 q/ha), respectively. On the basis of results emanated from the present investigation conducted during kharif2018, it was concluded that treatment 10×10cm crop geometry proved best in respect of maximum yield and productivity.
