Global consciousness of food safety, health and environmental issues has stimulated interest in alternative agricultural systems like organic farming. Since information on organic farming of tuber crops is meagre, a field experiment was conducted in split plot design over a five-year period at Central Tuber Crops Research Institute, India. The aims were to evaluate the impact of organic, c...

We screened the pharmacological effects of a 50% ethanol extract of Yacon tubers and leaves on spermatogenesis in rats. As a result, we found that Yacon tuber extracts increased sperm number and serum testosterone level in rats. It has been reported that the crude extract of Yacon tubers and leaves contain phenolic acids, such as, chlorogenic acid, ferulic acid and caffeic acid by HPLC/MS analy...

The yield and quality of field crops are affected by abiotic stresses such as water deficit, which can negatively impact crop growth, productivity, quality. However, nanotechnology holds great promise for increasing yield, maintaining quality, thus mitigating stresses. Therefore, the current study was conducted to examine influences 0, 50, 100 mg L?1 zinc oxide (ZnO) nanoparticles 25, 50 silico...

Cassava (Manihot esculenta Crantz) is the third-largest carbohydrate food source in tropical region after rice and corn. Its flesh used to produce foods, while other parts of plant are not fully exploited. This research aimed evaluatetheproximate composition cassava (Rayong 90 variety). Six different namely leaf, petiole, young stem, tuber, cortex periderm white variety plants were dried powder...

Pleurotus tuber-regium is a tuberous wild mushroom species, highly expensive, nutritious, very rich in proteins and known to possess medicinal values. The dwindling forests and the absence of commercial cultivation of this mushroom have resulted in scarcity of the sclerotia. The study was conducted to determine the optimum temperature, pH and light regime for the growth of P. tuber-regium and e...

Three inherent acidic chitinases were purified from yam aerial tuber by the application of quaternary ammonium ion detergent. For remoyal of the mucilage in the crude extract of aerial tuber, the effeets of various quaternary ammonium ion detergent were compared. Cetylpyridinium chloride effectiyely remoyed the mucilage and this method proyed to provide high recoyery of chitinase actiyity. Thre...

Porang (Amorphophallus muelleri) is a tuber plant that contains lot of glucomannan fiber. Glucomannan soluble fiber can form gel mimics the characteristics fat so it has potential to be used as replacer in high-fat products such cookies. The purpose this study was determine effect using on sensory acceptability and steps carried out were concentration porang flour (5 7.5%). Fat with firmness cl...

The potential of tuber flour of Ipomoea batatas (L.) Lam. cv. Brazlândia Branca (white sweet potato) as wound healing and antiulcerogenic agent was investigated in vivo in animal model. Excision on the back of Wistar rats was performed to induce wounds that were topically treated with Beeler's base containing tuber flour of white sweet potato at 2.5%. Number of cells undergoing metaphase and th...

3.5 ha of sweet potato were used to feed 30 crossbred Brahman bulls with an average weight of 184 kg and approximately one year old in an experiment to study the use of sweet potato in beef production. The five treatments were allocated to the experimental units in an unrestricted randomized block design. Treatments contained 0:100, 25:75, 75:25, 50:50 ant 100:0 ratios of tubers to sweet potato...

In attempt to produce buoyant feed for Catfish and Tilapia fishes without extrusion, twenty eight (28) iso-proteic (30% Crude protein) multi-caloric (21.00-40.00 Kcal/g) diets were formulated compounded with cooked uncooked Maize, Cassava, Wheat starches Aquatec-11 as binders. Duckweed Lemnna paucicostata, Baker‘s yeast Saccharamyces cerevisiae Honey comb (animal exudates) involved floating age...
