Increasing the yield of castor from 1 T/hectare per year (the average right now in India) to something much higher is a highly desirable outcome, but not very easy.
The best way to overcome yield challenge in castor industry is to concentrate more on research and development (R&D) area.
Many techniques are emerging in R&D sector to increase the yield of castor. These include
- Hybrids: Selection of Hybrids to increase yield, branching, non-shattering and high oil content. e.g.- HC1, HC2,…8 also, advanced hybrids like TSP 10R VP1 lata, etc.
- Cross Pollination: Under natural conditions, cross pollination in castor can exceed 80%, but the actual level of cross pollination is dependent on both genotype and environmental conditions. Germplasm storage under cryogenic conditions keeps up the viability of seeds even after 30 days
- Other techniques like enriching the soil with zinc content
