Study Notes

Harvesting and Curing

Harvesting at 100% neck fall and curing by windrow method are recommended.
Curing in the field should be done until the foliage turns yellow.
Artificial curing can be done by passing hot air at 27.35°C through the curing room, taking around 48 hours for complete curing at 60-75% humidity.

Storage

Thoroughly cured garlic bulbs can be stored in well-ventilated rooms.
Garlic with dried leaves can be stored by hanging in well-ventilated rooms, but this is not feasible on a commercial scale.
Garlic can be stored at a wide range of temperatures, but controlled conditioned storage is not necessary.
Cloves sprout quickly at 4.4°C and should be avoided, while storage at 0.5°C is satisfactory, but humidity should be monitored.
Garlic stored at humidity above 70% at any temperature develops mold and starts rotting.
Cold storage at 32-36°F and 60-70% relative humidity is possible.
UV light treatment for 30 minutes reduces storage loss to 8% in cold stores for 150 days.

Yield and Disease

Garlic yields 5-12 tons per hectare.
Diseases and insects affecting garlic are similar to those affecting onions.

Planting Material and Time

Single cloves are used as planting materials, and sometimes bulbils are also used.
Planting times vary by region: Ashoj-Mangshir for Terai, Shrawan-Magha for Mid Hill, and Baishak-Jestha for High Hill.

Spacing, Seed Rate, and Fertilizer

The recommended spacing is 15cm, and 25kg of cloves are required for 1 ropani of land.
1500 kg of well-rotten FYM or Compost should be applied at the time of soil preparation per ropani.
Fertilizer requirements are: Nitrogen (12 kg/ropani), Phosphorus (12 kg/ropani), and Potassium (4 kg/ropani).

Irrigation

First irrigation is given after sowing, and then the field is irrigated every 10-15 days until the season warms up.
Frequent irrigation is required during the growing season, but should be given sparingly when the bulbs are matured.
The last irrigation should be given 2-3 days before harvesting.

Intercultural Operation

First interculture is given with hand or khurpi one month after sowing.
Second weeding is given one month after the first weeding and hoeing.
Hoeing around 2 ½ months from sowing helps in setting bigger and well-filled bulbs.

Management

Sanitation of the field is essential.
Chemical control can be done by dusting with sulphur powder at 22 kg per hectare.

Introduction

Garlic belongs to the family Amarylidaceae.
It is an important bulb crop used as a spice or condiment throughout Nepal.
It is a rich source of protein, carbohydrate, vitamin A, and C.
Pungency in garlic is due to the presence of allyl methyl sulfide.

Varieties

Some popular varieties of garlic include Marpha local, Khumal Selection, Fawari, Rajli gaddi, G-41, and Selection-2.

Climate

Garlic grows under a wide range of climatic conditions, but cannot stand extreme temperatures.
It prefers a moderate temperature in summer and winter, with short days favorable for bulb formation.
It can be grown well at elevations of 1000 to 1300 meters above sea level.
Optimum temperature is 18-22°C.

Soil

Garlic can be grown in various soils, but loamy soils are best.
Soil should be well-drained, as badly drained soils can cause discoloration.
Heavy clay soil is not preferred due to harvesting difficulties.
pH requirement is 5-7.
