The purpose of the present study is to survey the extraction conditions and explore the antioxidant potential of the wild herb Cistus incanus, which is non-traditional in Bulgarian ethnomedicine and widespread in the Strandja Mountain. The influence of the extraction time (0-500 min) and solvent composition (0-50% ethanol in water) on the polyphenols, flavonoid yields and on the antioxidant cap...

Corn stover mass and moisture properties were identified to aid decisions regarding collection of standing corn stover dry matter with least moisture, and to aid development of moisture prediction tools for applications including harvest, transport, size reduction, and storage. Vertical distributions of mass and moisture in standing stalks and aboveground components such as leaf, husk, and ear ...

The southern root-knot nematode (Meloidogyne incognita) is a major parasite of cotton in the U.S., and management tactics for this nematode attempt to minimize population levels. We compared three post-harvest practices for their ability to reduce nematode population levels in the field, thereby reducing initial nematode population for the next year's crop. The three practices tested were: 1) c...

Gadam sorghum stalks are agricultural residues which can be hydrolyzed into fermentable sugars that used to produce bioethanol is a renewable source of energy. In order from lignocellulosic biomass such as stalks, several processes including hydrolysis involved. However, the use for production hindered by low yield obtained during hydrolysis. The lack sufficient information on optimal condition...

Local Pest, Disease and Variety Control Committee (LPD&VCC) Eldana saccharina survey records from 2001 to 2003 were analysed to investigate the pest status of this stalk borer in the South African sugarcane industry. Percentage stalks damaged, percentage stalk length red and numbers of larvae per 100 stalks varied in different mill areas, thus confirming previously published patterns. Furthermo...

This study examined chemical composition of tomato stalks and their possible feasibility in the production of particleboard. Three-layer experimental particleboards with density of 0.53, 0.63, and 0.73 g cm(-3) were manufactured from tomato stalks using certain ratios of urea formaldehyde (UF) and melamine urea formaldehyde (MUF) adhesives. Modulus of elasticity (MOE), modulus of rupture (MOR),...

In this study, steam explosion pretreatment was performed in cotton stalks, leading to 5-6 folds enhancements on biomass enzymatic saccharification distinctive in Gossypium barbadense and Gossypium hirsutum species. Sequential 1% H2SO4 pretreatment could further increase biomass digestibility of the steam-exploded stalks, and also cause the highest sugar-ethanol conversion rates probably by rel...

A survey conducted from May 1995 through August 1998 revealed diverse nematode communities in Louisiana sugarcane fields. High populations of Mesocriconema, Paratrichodorus, Pratylenchus, and Tylenchorhynchus were widespread in nine sugarcane production parishes. Comparisons of plant cane and ratoon sugarcane crops indicated that nematode community levels increase significantly in successive ra...
