Castor (Ricinus communis L.) is cultivated around the world because of the commercial importance of its oil. India is said to be the world’s largest producer of castor seed and meets most of the global demand for castor oil.
Nigeria imports over N30 billion worth of castor oil every year despite having arable and fertile land, and climatic conditions suitable for its farming. It is crystal clear that only very few Nigerians are taking advantage of the present opportunities in the different agriculture value chains.
Numerous opportunities abound in castor farming, as a potential farmer or investor can make up to N50 million on 10 hectares of land over a period of seven years due to its more than 1000 uses and over 80 health benefits.
Following the launch of its research project on opportunities for the Castor bean; and consultations with castor growers and processors last year, The Jamaica Promotions Corporation (JAMPRO) is executing a long-term strategy for the development of the castor industry for exports and investments.
The Agency will be hosting capacity building initiatives, business matchmaking opportunities, and has planned trade missions to assist local castor oil producers to enter international markets later this year.
Scientists from University of Hyderabad, India have found that castor bean plants could help in remediation of areas where soil has been highly polluted with heavy metals due to industrial pollution.
Castor plants growing in these areas absorb toxic heavy metals from soil. Hence, castor bean plants can be grown in such polluted lands and over a period of time the levels of heavy metals can be reduced in the soil.
Research reports stated that when the castor bean plants growing in industrial areas were tested, roots of the plants were seen to contain lead in as high as 19.53 milligrams per gram of the root. Even leaves and stem of the plant were found to be containing lead but in smaller quantities.
New cultivation technique boosts castor crop yield in Gujarat.
Gujarat based castor farmer has used organic fertilizers for castor crop cultivation and has reaped nearly six to eight tons of crop compared to four tons by others, with minimal amount being spent. He hopes that organic cultivation will help him reap atleast 20 quintals of castor seeds by the end of the season.
Initially the farmer had experimented this technique with a variety of paddy and had success. Later he tried the technique with castor crop and cultivated Palem Hybrid Castor EI-111 variety after consultation with the scientists in that region and now he has succeeded.
Agriculture department officials have predicted good price for the organically cultivated castor oil in the market. Government has allotted funds exclusively for vermicompost units to enable farmers cut costs and earn profits. These have enabled more farmers to shift to natural farming.
Castor cultivation which had lost interest among farmers since 2012 is now attracting farmers with new farming methods and cropping patterns. Castor cultivation was at its peak during 2010-11 due to high castor seed prices at around Rs. 6200 per quintal. The crop had become the most preferred for the kharif sowing.
But during 2012, as the prices started falling, the castor cultivation decreased and since then it has been decreasing, with prices of castor seed falling to Rs. 3325 – Rs. 3400 per quintal.
To increase castor yield and attract farmers, SEA started a Castor Yield Increase Programme where around 60 farmers and scientists of Dantiwada Agricultural University joined. The main objective was to reduce the use of water, pesticides, fertilizers and cut costs while raising the yield by changing the cropping pattern.
The new cropping pattern has attracted farmers as the castor seed yields have doubled. The Dantiwada Agriculture University has provided GCH 7, a new hybrid variety of castor seeds, free of cost to farmers.
SEA has also planned the pilot project to five districts of Gujarat and Rajasthan by including more farmers.
Here is a brief blog post which helps the castor farmers to understand the do’s and do not’s while cultivating castor. Article excerpts from http://www.ikisan.com
- For proper tilth and good seed bed preparation, plough the land immediately after pre-monsoon showers followed by 2-3 harrowings with blade harrow after rains.
- Farmers are required to purchase the hybrid seed from authorised registered seed agent and ensure its viability
- However, they need not renew seed stock of their improved varieties every year.
- Using certified seed once obtained from authorised agencies/sources, interested farmers can easily meet their requirement of quality seeds and maintain the varieties for atleast 3-4 years without any appreciable deterioration.
- Seed may be treated with Thiram or Bavistin 3g/kg seed to protect from seed borne diseases like Alternaria leaf blight, seedling blight and wilt.
- A plant population of 55,500/ha has been found to be optimum for rainfed castor in all regions
- For achieving required plant stands in dry lands, a seed rate of 10-15 kg/ha is adequate depending on seed size.
- The optimum date of sowing for castor in Andhra Pradesh is first fortnight of June.
- Plough with single seed drill help in placement of seed at appropriate moist zone and ensures better germination and growth.
- As far as possible place the seed in a moist zone 10-12cm below the soil surface to ensure proper moist soil seed contact for sufficiently long period and thereby obtain good germination.
