Boost Your Garlic Production
Garlic is a popular vegetable that is used in many cuisines around the world. It is a member of the Allium family, which also includes onions, leeks, and shallots. Garlic is known for its strong, pungent flavour and its numerous health benefits. It is a good source of vitamins B6 and C, as well as manganese and selenium. Garlic also contains a compound called allicin, which has been shown to have antibacterial and antifungal properties.
Garlic is grown in many countries around the world, with China being the largest producer. Other major producers include India, Bangladesh, and Egypt. Garlic is relatively easy to grow, and can be cultivated in a variety of soils and climates. It is typically planted in the autumn and harvested in the summer. Garlic can be grown from seed or from cloves, which are the small divisions that make up a bulb.

Garlic Botany and Varieties
Botanical Description
Garlic, scientifically known as Allium sativum, is a member of the Alliaceae family. It is a bulbous perennial crop that grows up to 60 cm tall. The garlic bulb is made up of several small sections called cloves, which are covered in a thin, papery skin. Each clove is capable of growing into a new bulb. Garlic has a strong, pungent flavour and aroma due to the presence of allicin, a sulphur compound.
Cultivar Selection
There are two main types of garlic cultivars: softneck and hardneck. Softneck garlic is the most common type and is often found in grocery stores. It has a milder flavour than hardneck garlic and has a longer shelf life. Hardneck garlic, on the other hand, has a stronger flavour and is often used in gourmet cooking. It is also more difficult to grow and has a shorter shelf life.
When selecting garlic cultivars for production, it is important to consider factors such as yield potential, disease resistance, and flavour. Some popular cultivars include ‘Inchelium Red’, ‘Chesnok Red’, and ‘Music’.
Climate and Soil Requirements
Garlic grows best in cool, temperate climates with mild winters and long, warm summers. It requires well-draining soil with a pH of 6.0 to 7.0. Heavy, poorly-drained soils should be avoided as they can lead to root rot.
Garlic is a heavy feeder crop and requires proper nutrition from planting to harvest. Soil must be enriched with animal manures or poultry manure at the rate of 5kg/ square metre and 150-200 g/ square metre respectively. This should be incorporated into the soil at least 10 days prior to planting. Two weeks after emergence, give Animal Liquid manure fertilizer @ 10 litres/ square metre as growth booster. At week 7-8 add either well-made compost @ 3-5kg/ square metre or chicken manure Liquid feed for bulb enhancement. This should be accompanied by mulching which must have been there from planting for better phosphoric usage and sulphur intake- essential elements in enlarging bulbs.
In terms of climate, garlic prefers a cool, dry environment. High humidity can lead to fungal diseases such as white rot and downy mildew. Garlic does not need any spraying of any kind as it has self-disease and insect repellent qualities.
Overall, garlic is a relatively easy crop to grow and can be a profitable addition to a small farm. With proper care and management, garlic can yield an average of 1-2 kg/ metre square, meaning a farmer can harvest an average of 5000kg/ (50m ×50m).
Cultivation Techniques
Garlic requires well-drained soil with a pH of 6.0-7.0. The land should be plowed at least twice, and any weeds, rocks, or debris should be removed. Soil enrichment is crucial for garlic production. Incorporating animal manures or poultry manure at the rate of 5kg/square meter and 150-200g/square meter, respectively, should be done 10 days before planting.
Planting Methods
Garlic is best planted after separating cloves from bulbs and later planted by inserting or pushing the cloves into the soil. It is best to peel the cloves by removing covers to ensure the best quality seeds. Peeled garlic germinates within 4-5 days compared to the unpeeled, which may take 10-20 days depending on soil type and irrigation frequency and efficiency. The best spacing is 5-8 cm between plants and 30cm between rows.
Irrigation and Water Management
Garlic requires consistent moisture throughout the growing season. Irrigation should be done immediately after planting and then every 7-10 days, depending on the weather and soil type. Over-irrigation should be avoided to prevent the development of fungal diseases.
Weed Control
Weed control is essential for garlic production. Weeds compete with garlic for nutrients, water, and sunlight, leading to reduced yields. Hand weeding, hoeing, and mulching are effective weed control methods. Mulching should be done immediately after planting to conserve moisture and control weeds.

Pest and Disease Management
Common Pests
Garlic is generally known to have self-disease and insect repellent qualities, but it is still susceptible to some pests. One of the most common pests that affect garlic is the onion thrips. These tiny insects cause damage by feeding on the leaves and bulbs and can spread diseases. Other pests that can attack garlic include aphids, mites, and nematodes. To prevent pest infestations, it is important to maintain good sanitation practices, rotate crops, and monitor the garlic plants regularly for signs of pests.
Disease Identification
Garlic is also susceptible to various diseases, including white rot, which is a fungal disease that affects garlic and other alliums. It is characterized by the yellowing and wilting of leaves, white fluffy fungal growth at the base of the plant, and black sclerotia (small, hard fungal structures) on the garlic bulbs and roots. Other diseases that can affect garlic include rust, purple blotch, and downy mildew. To prevent the spread of diseases, it is important to remove and destroy any infected plants and to practice crop rotation.
Integrated Pest Management
Integrated Pest Management (IPM) is a comprehensive approach to pest management that involves the use of various methods to control pests. These methods include cultural, biological, and chemical control methods. Cultural control methods include crop rotation, sanitation, and planting disease-resistant varieties. Biological control methods involve the use of natural predators or parasites to control pests. Chemical control methods involve the use of pesticides to control pests. However, it is important to use pesticides only as a last resort and to follow all safety precautions when using them.

Harvesting and Post-Harvest Handling
Garlic is usually ready for harvest after 12-16 weeks or 3-4 months after emergence. The bulbs protrude above ground level, and the foliage turns yellowish, signaling readiness for harvest. Harvesting techniques, curing, and storage are crucial to maintain the quality of garlic bulbs.
Harvesting Techniques
Harvesting garlic bulbs involves pulling them out of the ground with the mother attached stems, and then tying them in bundles of 15-20s. The bundles are then hung by tying with a rope and suspended on any pole or roofing rafters inside a building for gradual drying. It is recommended to avoid drying garlic in direct sunlight as it reduces its weight and natural juice quality.
Curing and Storage
After harvesting, garlic bulbs need to be cured and stored properly to maintain their quality. Curing is done to remove excess moisture from the outer skin and neck to reduce storage rot. The curing process involves placing the garlic bulbs in a warm, dry, and well-ventilated area for two to three weeks.
After curing, the garlic bulbs are ready for storage. The ideal storage conditions for garlic are cool and dry places with temperatures between 0-5°C and relative humidity between 60-70%. Garlic bulbs can be stored for up to 6-8 months under these conditions.
Quality Assessment
Quality assessment of garlic bulbs is necessary to ensure that only high-quality bulbs are selected for storage or sale. Quality assessment can be done by grading the garlic bulbs according to their size, colour, and shape. The bulbs can also be examined for any physical damage or signs of disease.
In conclusion, harvesting and post-harvest handling are critical stages in garlic production. Proper harvesting techniques, curing, and storage are necessary to maintain the quality of garlic bulbs and ensure their long-term storage. Quality assessment is also necessary to ensure that only high-quality bulbs are selected for storage or sale.
