Screening of suitable tossa jute (Corchorus olitorius L.) mutant to increase fiber production

Abstract: The present study was conducted at the research farm of Bangladesh Institute of Nuclear Agriculture (BINA) Sub-station, Gopalganj, to find out the effective mutant for increasing fiber production of jute during March – September 2019. Mutant lines (JRO-1000-8, JRO-1000-10, JRO-700-3, JRO-1000-9) and two check varieties (JRO-524, BJRI-8) were used in this study. The experimental design was a randomized completely block with three replications. Morphological characters, plant height and base diameter were studied for the screening of jute mutants for higher yield. Results indicated that the highest plant height (3.26 m) in JRO-524 and base diameter (6.88 cm) in JRO-1000-8 found in this study. On the other hand, the highest fiber and stick yields were found in JRO-1000-9 and JRO-524, respectively. JRO-1000-8 and JRO-1000-10 mutants produced higher stick yield than JRO-1000-9 mutant. BJRI-8 variety gave inferior results compared to all mutants and check variety JRO-524 except stick yield. The highest harvest index was observed in JRO-1000-9 and BJRI-8. JRO-1000-9 mutant produced 30.24% fiber yield over BJRI-8 check variety. Positive and significant correlation was found between plant height and stick yield of jute. It may be concluded that JRO-1000-9 was found to be the best mutant for increasing fiber production of jute.

Influence of organic wastes amendment on growth and foliar yield of jute mallow Corchorus olitorius (linn.) In South Western Nigeria

Abstract: This study investigated the growth and foliar yield responses of jute mallow ( Corchorus olitorius Linn.) on soils amended with ashed and unashed corn cob and coconut husk agro-waste. Slightly acidic (pH=6.20) sandy loam soil were collected and incubated for six and twelve weeks respectively for the study, with agro-wastes [coconut husk ash (CHA), coconut husk unashed (CHU), corn cob ash (CCA) and corn cob unashed (CCU)] under greenhouse conditions. A completely randomized design was adopted with three replicates. The results showed that the corn cob ash and coconut husk ash positively enhanced soil chemical properties than their unashed version. At 2 WAP, the mean plant height ranged from 2.70 ± 0.12 cm to 3.88 ± 0.12 cm; the mean total leaf count from 3.60 ± 0.05 to 4.0 ± 0.05 and mean leaf area from 0.54 ± 0.21 cm2 to 2.48 ± 0.21 cm2 and at 8 WAP, the mean stem girth ranged from 0.43 ± 0.07 cm to 1.02 ± 0.07 cm for C. olitorius planted in soils incubated for six weeks with agro-wastes. This trend increased with the age of C. olitorius and with increase in agro-waste applications in the order CCA>CHA>CHU>CCU. These growth parameters, except the plant height were of higher values in 6 weeks soil incubation than 12 weeks soil incubation. The highest mean yield (17.93 g/pot) of C. olitorius was obtained in soil pots amended for 12 weeks with 5 t/ha of CHU. The increase growth and foliage yield obtained in this study showed that soils amended with ashed and unashed corn cob and coconut husk waste have the potential of promoting the production of vegetables, especially C. olitoriu s and also ensuring environmental sustainability.

Pathogenicity of meloidogyne incognita on corchorus olitorius

Abstract: Summary Two experiments were carried out to study the pathoBenic effects of Meloidogyne incognita on two cultivars of Corchorus olitorius Plant height, mean number of leaves per plant, mean leaf area, fresh and dry shoot weight and chlorophyll content decreased with increases in initial inoculum levels far both cultivars in the two experiments NPK 15:15:15 was found to improve the tolerance of the plants infected by M incognita by markedly reducing the yield losses compared with plants which received no fertilizer treatment, even at lower inoculum levels lation each plant was cut through at the stem base and both fresh and dry shoot weight were then recordedRoots were uprooted and rated for galls using the 0-5 scheme of Taylor and Sasser (1978) A verage leaf area was determined by the Gunkel and MulIigan (1953)method using the relationship reported by Watson(1937) and Gunkel and MulIigan (1953) to calculate area thus: Corchorus olitorius L, an annual broadIeaf herbaceous and fibrous plant is an important crop in Nigeria where it is grown for the bast fibre and as a leaf vegetable It is susceptible to attack by various nematodes including Helicotylenchus spp, Scutellonema clathricaudatum and Hemicyclophora spp (Caveness, 1967) Meloidogyne spp may be particularly damaging (Quin, 1975) Babatola (1983) described the symptqms af attack as chlorosis, wilting, significant reductions in leaf size and total fresh weight, in addition to the characteristic gall of the roots This paper reports results of pathogenicity studies on C olitorius infected by Meloidogyne incognita (Kofoid et White) Chitw and the effect of NPK 15:15:15 fertilizer on such plants

Evaluation of the effects of Corchorus olitorius L. and Carapa procera in the treatment of obesity

Abstract: Background: The obesity remains a pathology today which expands. It leads in its wake much pathology with very serious consequences. It is therefore necessary to take steps to curb this nutritional pathology. Thus, two plant species including Carapa procera and Corchorus olitorius have been tested to assess their effect on this pathology. Methods: Aqueous extracts of Carapa procera bark and Corchorus olitorius roots were tested on rats and biochemical parameters were evaluated. Besides, a chemical characterization was led. Results: These plant extracts contain bioactive molecules that have a regressive activity on the plasma levels of cholesterol, triglyceride and LDL-cholesterol. These bioactive molecules increase the level of HDL-cholesterol. These 2 species are non-toxic on renal, hepatic and pancreatic functions in view of the values of urea, creatinine and blood glucose. Conclusions: Of these 2 extracts, the aqueous extract of Corchorus olitorius is more active.
