SOME IMPORTANT AGRONOMIC ASPECTS FOR CALOTROPIS PROCERA CULTIVATION
Although Calotropis procera can be germinated throughout the year however the suitable time for sowing of Calotropis procera is May-June. Suitable sowing depth for Calotropis procera is 3 to 4 cm. Calotropis does not require deep tillage. One irrigation should be applied immediately after sowing if there is no rainfall. The intensify of weeds badly affects the plant growth therefore it is prudent to eradicate them. Suitable time for weed erradication is 45 days after sowing. First harvest may be done after three to four months after sowing. Plants may be thinned to have suitable number of plant for per unit area for better plant growth. The suitable time for thinning is after about 45 days after germination. An experiment is in progress to determine the suitable density of plants in perunitarea.However for developing countries it is important to develop crop plants that grow on wastelands and are able to produce sufficient biocrude at economic costs. The present papers presented the details for strategy for wastland colonization using hydrocarbon yielding plants which could be employed for several developing countries (Kumar 1998).
