GARLIC (Allium sativum L)

Alliaceae

Varieties 
Ooty 1, Singapore red, Rajali, Tabiti, Cerole, Madrasii

Soil 
Garlic can be grown at elevation of 1200–2000 m from the mean sea level. It requires short days, cool (12–18 °C) moist period during vegetative growth. A well drained friable soil rich in organic matter with a pH range of 6 – 7 is ideal. Extreme acidic soils as well as heavy soils are not suited for this crop.

Season
In hilly areas it is grown in two seasons.
1st season: June – July
2nd season: October – November

Seed rate
500 – 600 kg/ha

Preparation of main field
Plough the land to a fine tilth and form ridges and furrows at 30 cm spacing or beds of convenient sizes. Cloves are planted at 15 x 10 cm spacing.

Irrigation
Irrigate before and after planting; life irrigation is given on third day of planting and at weekly intervals of time.

Application of fertilizers
During last ploughing incorporate 50 t/ha of FYM; Apply Azospirillum 2 kg and Phosphobacteria 2 kg/ha, 40:75:75 kg/ha NPK, 50 MgSO4 and 1 ton neem cake as basal and N 35 kg/ha at 45 days after planting.

Controlling rubberisation 
Avoid excessive application of N to minimise rubberisation. N should not be applied in the form of Urea. Use Ammonium sulphate. Spray 1500 ppm of CCC or MH on 30th day of planting. Reduce the frequency of irrigation to minimise rubberisation. Apply 0.2 % Boron 0.1 % Sodium molybdate on 30th, 60th and 90th days after planting.

After planting
Weeding should be done on 30th and 60th after planting.

Plant protection
Pests
Thrips

Thrips can be controlled by spraying Methyl dematon 25 EC 1 ml/lit.

Nematode
Nematode can be controlled by the application of Carbofuran 3 G 1 kg a.i./ha 30 days after planting.

Disease 
Clove rot

Before planting treat the cloves with Carbendazim 2 g/kg.

Harvest
Turning of tops to yellowish or brownish colour and starts drying is the ideal harvest index for harvesting garlic.

Yield
8 – 12 t/ha
