TL;DR: In this article, the authors report on the moisture regain, relative vapor pressure, hysteresis, and mechanical properties of two varieties of jute fibers, Corchorus capsularis grade 2 and corchorus olitorius grade 2, modified by treatment with sebacoyl chloride, tolylene diisocyanate unsaturated polyester resin, vinyl ester resin, γ-aminopropyl trimethoxy silane, and isopsropyl triisostearoyl titanate.
Abstract: We report on the moisture regain, relative vapor pressure, hysteresis, and mechanical properties of two varieties of jute fibers. Corchorus capsularis grade 2 and Corchorus olitorius grade 2, modified by treatment with sebacoyl chloride, tolylene diisocyanate unsaturated polyester resin, vinyl ester resin, γ-aminopropyl trimethoxy silane, and isopropyl triisostearoyl titanate. All the treated fibers showed a reduction in moisture regain, but some fibers had superior moisture repellent behavior with no deterioration in their mechanical properties, while others suffered a loss in mechanical properties.

TL;DR: Jute (Corchorus olitorius) belongs to the family Tiliaceae as mentioned in this paper and it is grown in Nigeria and many tropical countries for its nutritious young leaves which in SW Nigeria are cooked into a paste and eaten with starchy staples.
Abstract: Jute (Corchorus olitorius) belongs to the family Tiliaceae. Though mostly known for its fibre (Tossa jute), it is grown in Nigeria and many tropical countries for its nutritious young leaves which in SW Nigeria are cooked into a paste and eaten with starchy staples. Immature fruits, called 'Bush Okra', are also eaten. The plant thrives in sunny spots on soils rich in organic matter and with abundant moisture. Propagation is by seed and dormancy is broken by briefly steeping in hot water. Pests are mainly caterpillars and mites that feed on leaves, and Meloidogyne nematodes which greatly reduce yields; but diseases are few and not serious. Current emphases of breeding plants are for early varieties with high harvest index.

TL;DR: In this paper, the phenolic acid contents of jute plants were quantitatively determined by means of HPLC and the main components were Ferulic and p-coumaric acids, whereas p-hydroxybenzoic, protocatechuic, vanillic and caffeic acids were present in varying amounts in different jute fractions.
Abstract: Fresh and retted bark and stem of the Corchorus capsularis and Corchorus olitorius species of jute plant were analysed for their phenolic acid contents. Free and bound phenolic acids were identified and quantitatively determined by means of HPLC. Ferulic and p-coumaric acids were the main components, whereas p-hydroxybenzoic, protocatechuic, vanillic and caffeic acids were present in varying amounts in different jute fractions. The stem contained more free phenolic acids than the bark, and the differences were very pronounced in the retted samples. On the other hand, the bark from all four samples contained more extractable ester-bound phenolic acid than the stem. The stem of fresh C. olitorius and retted bark (fibre) of both species contained more non-extractable bound phenolic acids, in particular p-coumaric acid, than the other fractions.

TL;DR: The lesion nematode Pratylenchus coffeae (Zimmerman) Filipjev et S. Stekhoven was found in 18% of soil samples during a survey of jute Corchorus olitorius L. fields and the lowest inoculum density that causes damage was established.
Abstract: The lesion nematode Pratylenchus coffeae (Zimmerman) Filipjev et S. Stekhoven was found in 18% of soil samples during a survey of jute Corchorus olitorius L. fields (Laha et aI., 1981). Its pathogenicity on jute has not been established and therefore an experiment was conducted to establish the lowest inoculum density that causes damage.

TL;DR: Permanent mulching with straw of Imperata cylindrica reduced the mean maximum 2 cm soil temperature by about 6 o C and decreased mean emergence time of both crops between 2 and 8 days when compared with unmulched plots.
Abstract: Soil temperature variations were modified through different lengths of mulching period in the field and their consequent effects on seedling emergence of Abelmoschus esculentus and Corchorus olitorius studied. Permanent mulching with straw of Imperata cylindrica reduced the mean maximum 2 cm soil temperature by about 6 o C and decreased mean emergence time of both crops between 2 and 8 days when compared with unmulched plots
