Know the reasons for premature tuber sprouting in the main field in garlic crop

Know the reasons for premature tuber sprouting in the main field in garlic crop

Garlic bulbs are sometimes observed to germinate in the field at the beginning of the maturity stage of the bulb, especially when it rains in the winter season or due to excess soil moisture and nitrogen supply. Also, this problem in garlic is caused by irrigation more often than the normal requirement in the crop.

Short-duration varieties are more susceptible to this problem than long-duration varieties. Delayed harvesting in the rainy season leads to premature germination and cracking of tubers. Also, the wide spacing of cloves at the time of planting increases the absorption of nitrogen and water by individual plants, resulting in premature germination.
