Review on Effects of Inter and Intra Row Spacing on Production of Garlic (Allium Sativum L.)

Garlic is propagated by means of cloves and this vegetative propagation leads to infection by several viruses, which are called garlic viral complex. Planting density is one of the main factors that have an important role in the growth, yield, and quality of onions. Garlic yield mostly depends on the number of plants per unit area. Increase in yield and for bulb grade improvement planting garlic at proper spacing is considered a necessary practice. Considering the importance of garlic as one of the potential vegetable crops for both domestic consumption and export, it is imperative to increase its productivity along with appropriate use of inter and intra-row spacing. Therefore the review is undertaken to review the status of the optimum inter and intra-row spacing for garlic production. The Latin term for garlic is allium. It belongs to the monocot group of flowering plants known as the onion genus. The number of plants per square foot has a major impact on garlic yield. Garlic planting at the right spacing is thought to be a crucial practice for improving bulb quality and productivity. The low production of garlic in Ethiopia is caused by a variety of biotic and abiotic problems, including ineffective fertilizer application, diminishing soil fertility, improper agronomic techniques, and improper inter- and intra-row spacing. Planting distance is regarded as a crucial management strategy in the production of garlic. Reviewing the best inter- and intra-row spacing for garlic production is the goal.
