PESTICIDAL EFFECT OF SELECTED PLANT EXTRACTS ON Polyphagotarsonemus latus (BANKS) INFESTATION IN Corchorus olitorius L. JUTE

Abstract: Many plant extracts could be considered as natural effective tool against yellow mite instead of synthetic chemicals. The research was aimed at studying the effects of plant extracts on Polyphagotarsonemus latus Banks infestation and jute yield production. This experiment was conducted in Manikganj, Bangladesh following randomized complete block design with three replications. Treatments were Neem oil 3% (T1), Neem leaf extract @ 1:30 (T2), Mahagoni seed extract @ 1: 10 (T3) Turmeric powder extract @ 1: 40 (T4), Garlic paste extract @ 1:30 (T5) and control (T6). Percent reduction of mite population was found in neem oil (87.94%), neem leaf extract (85.76%) and garlic paste extract (86.48%) at 72 hrs after spray. After 7 days of spraying, Neem oil treated plot received the best reduction (89.05 %) followed by neem leaf extract (87.03%), Mahogany (79.60%), turmeric (78.02%), and garlic (80.06%), respectively. Neem oil treated plot showed highest fibre yield (2.95tha-1). Control plot showed highest mite infestation with lowest yield contributing attributes. Neem oil/leaf extract and mahogany seed extracts were found effective to control yellow mite infestation resulting higher fibre yield production.

Determination of β-carotene in jute leaves by spectrophotometry and thin layer chromatography

Abstract: β-carotene is a carotenoid pigment that converts to vitamin A in human body and plays crucial role in visual functions, reproductive performance and immune system. Jute leaves contain β-carotene but amounts in different varieties of jute leaves are not known. The study was undertaken to estimate the β-carotene content in fresh jute leaves of the cultivated jute species Corchorus olitorius L. and Corchorus capsularis L. by spectrophotometry and thin layer chromatography. β-carotene content varies in leaves of different varieties of two species. Leaves of some C. olitorius variety showed higher amount of β-carotene than the leaves of C. capsularis variety. Some varieties of C. olitorius showed similarity with some varieties of C. capsularis. Variety Robi-1 of C .olitorius showed the highest content of β-carotene 39.93mg/100g. O-72, O-4, O-3820, O-9897 and OM-1 of olitorius variety showed higher β-carotene than all the varieties of C. capsularis. JRO-524 and MG-1 of C. olitorius variety is comparable to CVL-1, D-154, BJC-2197 and deshi pat shak-1 variety of C. capsularis regarding β-carotene content. Lowest β-carotene was estimated 12.55mg/100g in O-795 of olitorius variety and 12.32mg/100g in BJC-83 and 11.34mg/100g in BJC-2142 of capsularis variety. Thin layer chromatography system silica gel on TLC Al foils as stationary phase and hexane as mobile phase performs good separation and identification of β-carotene in jute leaves.

Interspecific Hybrids of Jute between Corchorus olitorius L. and Semi-wild C. capsularis L.

Abstract: Hybridization between Corchorus olitorius L. and C. capsularis L. was repeated by changing the variety of one of the parents. Using a semi-wild species of C, capsularis, namely, Lalnaris as male parent instead of the cultivar D154, much F1 hybrids were obtained whereas in the earlier cross application of hormone as well as embryo culture were necessary to obtain F1 hybrids. When Lalnaris was used there was no necessity to use either hormone or embryo culture to obtain fruit set. The F1s obtained in the present investination showed heterosis in respect of height and there was iess varia-bility in the F2' They also showed more pollen and seed fertility than the F2S reported earlier.

Enhancement of polyphenols and antioxidant and inhibitory properties of Corchorus olitorius and Amaranthus hybridus leaves by the Ultraviolet-C treatment

Abstract: Article history: Received: January 9, 2020 Accepted: July 6, 2020 The effect of the postharvest (Ultraviolet-C) treatment on total phenolics, total flavonoids, total antioxidant capacity, 1,1-diphenyl-2-picrylhydrazyl scavenging activity (DPPH), and reducing power of Corchorus olitorius (CO) and Amaranthus hybridus (AH) was investigated. Their abilities to inhibit induced lipid peroxidation, α-amylase, and α-glucosidase after the ultravioletC treatment were also evaluated. The leaves were exposed to ultraviolet-C radiation for 10 min. Total phenolics, total flavonoids, total antioxidant capacity, DPPH scavenging ability, and reducing power were significantly (p < 0.05) increased after the ultraviolet-C treatment. Also, their abilities to inhibit SNP-induced lipid peroxidation, α-amylase and α-glucosidase were also enhanced significantly (p < 0.05). Therefore, apart from using ultraviolet-C radiation in water purification, it can be used to enhance health-promoting components in fruit and vegetables.
