Tuber pseudoexcavatum, Tuber sinoaestivum, and Tuber indicum are the 3 most important truffles growing in southeast China; however, their cultivation is still inefficient owing to the lack of understanding regarding the composition and function of the bacterial and fungal communities from the soils around the fruit bodies and the ectomycorrhiza of these truffles. The aim of this study was to di...

life cycle assessment (lca) had proven to be an appropriate assessment tool for analysis of agri-food products by identifying, quantifying and evaluating the resources consumed and emissions released into the environment. this study was performed for evaluation the environmental impacts of potato agroecosystems based on nitrogen levels by using lca methodology. tuber yield mean during 1999-2013...

an investigation was carried out to reveal the changes in the concentration of soluble carbohydrates under tuber dormancy in food yam (dioscorea esculenta) tubers and in an economically important spice cum medicinal plant turmeric (curcuma longa) rhizomes under storage. harvested, fully matured tubers of yam and rhizomes of turmeric were stored in wooden boxes under the conditions of 28 ? 2?c t...

Taro tuber, which has the scientific name of Colocasia esculenta, is grown in Vietnam. The nutritional compositions taro tuber are mostly starch, vitamin, protein, lipid, cellulose, and mineral. purpose this study was to determine changes physicomechanical, nutritional, sensory indicators tubers at different harvest times. were determined three harvesting stages 280, 300, 320 days. As a result,...

storage of potatoes is very important because fresh potatoes are available only for a few months in a year. thus, any treatment such as irradiation that controls sprout growth and extends shelf life of potatoes could be beneficial. in this study, potato sprout inhibition and tuber quality after treatment with various levels of gamma irradiation (0, 50, 100 and 150 gy) on different dates (10, 30...

A total of sixty, 14-day old broiler chickens (Cobb-500) of either sex were used in this study to assess the effects of processed cassava tuber meals (0, 15, 30, and 45 gkg) on growth responses, meat yield, and profitability of boilers; rearing from day 14 to day 33 of ages. The experimental diets were iso-caloric and iso-nitrogenous in nature, and were supplied the broilers ad libitum througho...

potato virus y (pvy) and potato leafroll virus (plrv) are two major viruses which reduce 10-90 percent of yield and quality of potato tubers. in the present study, the efficiency of different methods, including meristem culture, thermotherapy followed by meristem culture and electerotherapy followed by meristem culture in two cultivars (agria and marfona) infected by plrv or pvy were evaluated....

Pratylenchus penetrans suppressed the tuber yields of potato cultivars 'Katahdin', 'Kennebec', and 'Superior', but did not affect yields of 'Russet Burbank'. In comparison with noninfested controls, all initial nematode densities (P(i)) of P. penetrans (P(i) = 38, 81, 164, 211/ 100 cm(3) of soil) suppressed yields of Superior; a moderate P(i) (81/100 cm(3) soil) suppressed yields of Kennebec; a...

The study was initiated to generate genetic information on important yield contributing characters of sweet potato genotypes maintained in Chhattisgarh. Twenty eight potatoes (Ipomea batatas L.)  were evaluated estimate the variability for different characters. experiment conducted using a Randomized Complete Block Design with three replications. parameters studied. Analysis variance showe...

Two crop growth experiments in the soil-based closed ecological facility, Laboratory Biosphere, were conducted from 2003 to 2004 with candidate space life support crops. Apogee wheat (Utah State University variety) was grown, planted at two densities, 400 and 800 seeds m-2. The lighting regime for the wheat crop was 16 h of light-8 h dark at a total light intensity of around 840 micromoles m-2 ...
