Food containing tea leaf

Abstract: PURPOSE:To obtain a tea leaf-containing food enabling easy intake of effective amounts of minor nutrients such as various vitamins and minerals liable to be deficient in present Japanese or tannins such as catechin which is recently attracting attention as a substance for controlling physical conditions. CONSTITUTION:This food contains non-fermented tea powder and powder of arbitrary one or more kinds of vegetables selected from MOROHEIYA (Corchorus Scapsularis L. or Corchorus Olitorius L.), shiitake mushroom (Lentinus edodes, Zea mays L.), Lotus (Nelum bonucifera GAERTN.), carrot (Daucus carota L.), persimmon (Diospyros kaki L.), soybean (Glycine hispida Max.), garlic (Allium sativum L.) and guava (Psidium spp.) as essential components. The non-fermented tea is preferably deep-steamed tea.

Effect of Citric Acid on Cadmium Ion Uptake and Stress Response of Hydroponically Grown Jute Mallow ( Corchorus olitorius )

Abstract: This research work investigates the possibility of improving the phytoextraction of Cd by the application of citric acid. For this purpose, plants were grown in hydroponics under controlled conditions. Addition of 1, 5, 10 and 20 mg/L, Cd2+ significantly decreased the plant growth and biomass, and increased proline contents. The effects were dose dependent with obvious effects at higher Cd2+ concentration of 20 mg/L. Application of 5mM citric acid (CA) significantly depressed Cd2+ uptake and its accumulation in plant roots and shoots. CA alleviated Cd2+ toxicity by reducing oxidative stress. Application of CA also enhanced the antioxidant enzymes activity alone and under Cd stress. The results showed that Cd2+ accumulated more in roots than the shoots and application of citric acid depressed Cd2+ uptake at all concentrations. Jute mallow (Corchorus olitorius) proved to be an effective accumulator for cadmium, however, neither concentration of citric acid showed advantages for phytoextraction of cadmium. The results showed that jute mallow is a potential plant for phytoextraction of Cd without the use of CA as enhancer.

The role of corchorus in spreading of tomato yellow leaf curl virus on tomato in Jeddah, Saudi Arabia.

Abstract: Corchorus (Corchorus capsularis L. and Corchorus olitorius L.) is one of the most important fiber crops grown in tropical and subtropical regions throughout the world. Field survey was conducted and naturally infected leaf samples were collected from corchorus and tomato plants in Jeddah, Saudi Arabia. The causal virus was transmitted by whiteflies to tomato plants and begomovirus infection was confirmed by Polymerase chain reaction. The complete viral genome and associated betasatellites were amplified, cloned and sequenced from both corchorus and tomato samples. The genetic variability and phylogenetic relationships were determined for both isolates (corchorus and tomato). The complete genome sequences showed highest (99.5 % nt) similarity with tomato yellow leaf curl virus (TYLCV) and formed closest cluster with TYLCV-Tomato reported from Jizan and Al-Qasim, Saudi Arabia and betasatellites sequences showed highest similarity (99.8 % nt) with Tomato yellow leaf curl betasatellites-Jeddah followed by Tomato yellow leaf curl Oman betasatellites and formed closed cluster with TYLCV-Tomato. On the basis of results obtained from whiteflies transmission, sequence similarity and phylogenetic relationships; it is concluded that the identified virus could be a variant of TYLCV circulating in the Kingdom. The significance of this study demonstrated that the corchorus is serving as reservoir and alternative host and playing an important role in spreading the begomovirus associated disease in the Kingdom of Saudi Arabia.

Response of Jute Mallow ( Corchorus olitorius L.) to organic manure and inorganic fertilizer on a ferruginous soil in North-eastern Benin

Abstract: Objective : The study aimed to evaluate the effects of three types of fertilizers (Municipal solids waste compost, cow dung and chemical fertilizer) on growth characters and leaf yield of Corchorus olitorius under irrigated conditions Methodology and results : A field experiment was conducted in Parakou in the dry season using a randomized complete block design with three factors and twelve treatments: 1) Municipal solids waste Compost (MSWC) at 0, 10, 20 and 30 t.ha -1 ; 2) Cow dung at 0, 10, 20 and 30 t.ha -1 ; Urea fertilizer (46% N) at 0, 50, 100 and 200 kg.ha -1 . The plant height and stem diameter were significantly higher with Compost (20 t/ha) and lowest was recorded in control at all growth stages. The application of compost, cow dung and chemical fertilizer significantly increased the total number of branches at all growth stages. The highest number was recorded in MSWC 20 t.ha -1 as compared to the other treatments. The highest marketable leaves yield was obtained with MSWC at 20 t.ha -1 (8.1 t.ha -1 ) followed by MSWC at 30 t.ha -1 (6.6 t.ha -1 ), cow dung at 30 t.ha-1 (5.4 t.ha -1 ) and urea at 100 kg.ha -1 (5.4 t.ha -1 ), while control recorded lower values. A significant quadratic response on fresh leaf yield was observed with MSWC leading to a maximum of yield of 8.15 t.ha -1 at 23.03 t.ha -1 . Conclusion and application of results : The results indicated that the MSWC performs better when used at the optimal rate (23.03 t.ha -1 ), and can be used as a promising fertilizer source in Corchorus olitorius production in Benin.

Management of Macrophomina Disease Complex in Jute ( Corchorus olitorius ) by Trichoderma viride

Abstract: An experiment was conducted in RBD with seven treatments in four replications with olitorius jute variety JRO524 for five consecutive years (2002-07) at the experimental farm of the Crop Research Station, Bahraich in a plot size of 3X5 m 2 with a row spacing of 30 cm Recommended doses of N:P:K @ 60:30:30 kg ha -1 were applied The treatment with soil application of Trichoderma viride thrice, ie, 7, 15, 30 DAS was found best in controlling seedling blight, collor rot, stem rot and root rot diseases giving minimum per cent disease incidence (145, 307, 470 and 492, respectively) as compared to control (1612, 947, 1667 and 1634, respectively) Soil application with T viride twice (7 and 15 DAS) showed 205, 442, 614 and 615% incidence of the same diseases and ranked second The treatment with carbendazim 50WP @ 2g kg −1 , seed showed 852% seedling blight 524% collor rot, 693% stem rot and 856% root rot incidence Mean dry fibre yield was highest (2570q ha −1 ) in the plots when the soil was treated with T viride at 7, 15 and 30 DAS, while it was lowest in control (1776q ha −1 ) and in carbendazim treatment it was 2223q ha −1 Variation in yield was due to the variations in plant height and basal diameter
