Castor seed prices increased due to increased demand from the crushers on the s
pot, while there was a decrease on futures as traders booked the profit at higher level.
The export demand for castor oil had increased the demand from crushers. The price of the castor oil was up Rs. 5 to Rs. 830/10 kg.
Scientists from India performed an experiment to analyse the differential longevity of castor germplasm conserved under uncontrolled storage conditions. Seed longevity of 2961 castor accessions stored for <1-19 years under ambient conditions was investigated to analyse the loss in vigour by the castor seed and also 
determine the genetic variability for seed longevity.
Results showed that castor seed retained 40% germination even after 19 years of storage. All the accessions maintained 100% germination for one year, but from the second year, differential germination percentage was observed among accessions stored for the same duration.

Researchers from Tanzania conducted an experiment to stabilize cadmium sulphide quantum dots with the help of castor oil and ricinoleic acid. Cadmium sulphide quantum 
dots capped with castor oil and ricinoleic acid were prepared and analysed using various characterization techniques.
Results from all the characterization studies confirmed the formation of spherical shaped castor oil and ricinoleic acid capped cadmium sulphide quantum dots.
Scientists from Japan conducted an experiment to increase the toughness of poly(L-lactide) (PLLA) with the help of polyester urethane networks obtained from castor oil based oligomers. Hydroxy-terminated castor oil-modified ɛ-
caprolactone oligomers (CO-CLOns) were prepared by ring opening polymerizations of ɛ-caprolactone initiated with castor oil. It was then allowed to react with poly(L-lactide) which produced semi-interpenetrating polymer networks composed of TDI-bridged CO-CLOn networksand PLLA.
DSC analysis revealed that TCO-CLO10/PLLA 75/25 exhibited the highest tensile toughness compared to other polymer networks.

Castor seeds are being sold at the rate of Rs. 4000/quintal in Andhra Pradesh and
Telangana owing to steady export demand and increased acreage in the kharif season.
Earlier, during the sowing season, prices surged from Rs. 3900/quintal to Rs. 4200/quintal due to slow progress of sowing in Gujarat and Andhra Pradesh.
Italian synthetic fibre business Fulgar has launched a new high performance nylon fibre
made from biopolymer extracted from castor oil seed.
The fibre, Evo, is suitable for all applications, particularly, for the sports sector as it is ultra-light, stretchy and easily breathable.

Sufficient supply along with limited demand reduced the castor seed price in the spot 
market. Castor seed futures traded lower on higher supply as well as strong production estimates.
The castor seed prices declined Rs. 5 to Rs. 790 – 800 per 20 kg in Gujarat. On the Rajkot Commodity Exchange, castor December contract lost Rs. 21 to Rs. 4,122 per quintal. RCX spot castor declined Rs. 25 to Rs. 3,925 per quintal.
