CROP HUSBANDRY-CHILLI CULTIVATION PRACTICES IN KERALA

CHILLI (Capsicum annuum)

Varieties

High yielding varieties: Jwalasakhi, Jwalamukhi, Jwala, Pant C-1, K-2
Bacterial wilt resistant varieties: Manjari, Ujwala, Anugraha

Seed rate: 1.0 kg/ha

Raising seedlings


Chilli is a transplanted crop. Seeds are sown in the nursery and one-month-old seedlings are transplanted to the main field. For sowing the seeds, raised seed-beds of 90 to 100 cm width and of convenient length are prepared to which well decomposed organic matter has been incorporated. After sowing the seeds, mulch with green leaves and irrigate with a rose-can daily in the morning. Remove the mulch immediately after germination of the seeds. Restrict irrigation one week before transplanting and irrigate heavily on the previous day of transplanting.

Time of planting


For a rainfed crop, transplant the seedlings during May-June before the onset of southwest monsoon. Planting can also be done during Sept-October for an irrigated crop.

Land preparation and transplanting


Land is prepared to a fine tilth by thorough ploughing / digging. Well rotten organic manure is incorporated in the soil and seedlings are transplanted in shallow trenches / pits during May or on ridges / level lands during rainy season. Transplanted seedlings may also be given temporary shade for three to four days during summer.

Spacing

Transplant less spreading varieties at 45 x 45 cm. For spreading cultivars like White Kanthari provide a wider spacing of 75 x 45-60 cm.

Manuring

Apply well rotten FYM / compost @ 20-25 t/ha at the time of land preparation and mix well with the soil.
A fertilizer dose of 75:40:25 kg N:P2O5: K2O / ha may be given. Half of nitrogen, full phosphorus and half of potash may be applied as basal dose before transplanting. One fourth of nitrogen and half of potash may be applied 20-30 days after planting. The remaining quantity may be applied two months after planting.

Aftercultivation


Irrigate at three to four days interval during summer. Stake the plants if necessary. Weeding followed by fertilizer application and earthing up may be done at one and two months after transplanting.

Plant protection


For avoiding damping off of the seedlings in the nursery, sow the seeds as thin as possible in raised beds prepared in the open area during summer months. Spray nursery and main field with 1% Bordeaux mixture at monthly intervals during rainy season. Uproot and destroy the plants affected by bacterial wilt and mosaic.
Cultivate resistant varieties like Manjari, Ujwala and Anugraha in bacterial wilt prone areas.
Spray quinalphos 0.025% for control of mealy bugs and lace wings. Dimethoate at 0.05% is effective for controlling mites, aphids and other sucking insects.
