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
It can be grown at an elevation of 1200 – 2600 m from the Mean Sea Level (MSL). It requires short days, cool (12–18 °C) moist period during vegetative growth and bulb formation phase
In hilly areas it is grown in two seasons
Irrigated : March-April and Oct – Nov
Rainfed : June – July
1500 – 1600 kg/ha
Seeds are to be treated with Pseudomonas and Trichoderma @2 kg/ha
Cloves are planted at 15 x 7.5cm spacing
During last ploughing 50 t/ha of FYM; Apply Azospirillum 2 kg and Phosphobacteria 2 kg/ha 75:40:40 kg/ha NPK and 40 Kg Sulphur are to be applied. Nitrogen should be applied in the form of Ammonium sulphate
N should not be applied in the form of urea. Spray 1500 ppm of CCC or MH on 30th day of planting. Frequency of irrigation is reduced to minimise rubberisation , 0.2 % Boron, 0.25 % Zinc sulphate are applied on 30th, 60th and 90th days after planting
16-17 t/ha
Thrips
Thrips can be controlled by spraying Imidacloprid @ 25 EC 0.1% and the spread of viral infestation may be controlled.
Nematode
Nematode can be controlled by the application of Carbofuran 3 G 1 kg a.i./ha during 30 days after planting or by application of Paecilomyces lilacinus @ 2.5 kg/ha
Purple blotch : Seeds are treated with captan or thiram @ 3 g per kg seed
Clove rot: Before planting the cloves are treated with carbendazim@ 2 g/kg of seed bulbs
