ESTATE CROPS NNOVATION- Current cocoa plant production in East Nusa Tenggara (Nusa Tenggara Ttimur), Indonesia is low i.e. only 526 kg/ha, which according to the Directorate General of Estate Crops in 2009 it was only 228 kg/ha. The low productivity is partly due to low quality of planting materials and land conditions are marginal. Rainfall is only about 1200 mm with 6-8 dry months (rainfall <60 mm per month) per year.
Fortunately, it has been found a new clone with the potential yield from 2000 to 3000 kg of dry beans/ha, i.e. ICCRI 03, ICCRI 04 and Sulawesi 01, Sulawesi, 02 clones, while SCA 6 clone with a productivity of about 1.5 tons . in addition to that, a rootstock tolerant to moisture stress has also been found i.e. SCA 6 and SCA 12.
ICECRD has acquired the technology of cultivation of cocoa lindak, superior clones adaptable to specific dry land dry climate in East Nusa Tenggara. Planting materials in the form ofshoots grafting have been prepared at the Indonesian Center for Coffee and Cocoa Research in Jember. Seedling growth reflected by high-shoots, diameter, leaf number and leaf area of shoots did not show differences between the clones.
