Aftercare in Cardamom Cultivation
Fallen leaves of the shade trees are applied during Nov.-dec. to reduce the ill-effects of drought prevailing for 4t5 months in summer. Exposing the panicles over the mulch is beneficial for bee pollination.
Depending upon the intensity of weeds, 2-3 weedings are given,in May-June, Aug.-Sept. and pec-Jan. Spraying of Paraquat (625 ml in.500 litres.of water/ha) should be done only in interspaces between rows leaving 60 cm around the plant base.
Treshing removes old and drying shoots of plants. It is done once in a year with the onset of monsoon under rainfed conditions and 2-3 times in high density plantations provided with irrigation facilities.
Light shade is more favourable in the initial stages to enhance vegetative growth. In areas having sparse tree growth, suitable fast growing shade trees should be planted. Permanent shade trees like cedar, balangi and elangi are suitable. To provide adequate light during monsoon, shade regulation may be taken up in May before the onset of the monsoon. Two tier canopy-is desirable with a height not more than 3 m between the lower and higher canopy. Areas exposed to western side should have adequate shade.
1. Cardamom plantations are irrigated from last week of Jan. to mid May.
2. The plantations may be irrigated at 10-15 days interval till the onset of monsoon.
3. Regular irrigation (25 mm – 375 mm / irrigation) helps in initiation of panicles, flowering and fruit set.
4. The moisture level should be maintained- above 45-50%.
