Influence of Different Levels of Nitrogen and Spacing on Growth, Yield and Quality of Garlic (Allium sativum L.) cv. G-1

The results of study clearly shown that 140 kg N/ha significantly increased all the growth parameters (plant height, number of leaves, length of leaves), yield attributes (weight of bulb, bulb diameter, number of cloves etc.) and TSS content of Garlic bulbs.Similarly, wider spacing 20×10 cm significantly increased growth and yield parameters of garlic and followed by 15×10 cm.The interactive effect of nitrogen 140kg N/ha along with 20×10 cm spacing were found significantly superior with respect to weight of bulb (38.07 and 32.35 g), yield kg per plot (4.05 and 3.69 kg) and yield q ha -1 (133.05 and 115.85 q/ha), respectively .Maximum net returns (Rs.164896 and 140120) and B:C ratio (4.75 and 4.04) were obtained when higher dose of nitrogen 140 kg N/ha along with 20×10 cm spacing (T9-N3S3), followed by treatment T6-N2S3 (100kg N/ha with 15×10 cm spacing), respectively.Further, it may be concluded that sowing of garlic cv. G-1 application of 140 kg N ha -1 along with 20×10 cm spacing can be used in nitrogen deficient soils of Kota region to get significantly better yield, net return and B:C ratio. Otherwise in normal soils of Rajasthan 100 kg N ha -1 along with 15×10 cm spacing would be recommended for better yield.
