Two early- (EG) and two late-season (LG) corn-residue grazing trials were conducted either from October to December or from December to March (1987 and 1988) using both nonirrigated and irrigated fields. Initial availability, disappearance, and nutritive value of different corn residue components were estimated. Stocking rates were 1.97, 2.20, 1.36, and 2.58 animals/ha for the two EG and LG non...

The behavior of red-winged blackbirds {Agelaius phoemcei/s), common grackles (Quiscalus quiscula), brown-headed cowbirds (Molothrus ater), and juvenile European starlings (Sturnus vulgaris) feeding on ears of corn was studied in an aviary. The species differed significantly in their propensity to attack (penetrate the husk and feed on kernels) ears of corn. Redwings and starlings were more acti...

In rural areas of developing countries, there is a lack of sanitation services and the installation of such infrastructure is hampered by the high investment costs for initial implementation and by the limited availability of qualified personnel. An alternative to traditional sanitation services include an anaerobic filter, but the high cost of appropriate filling material can be an obstacle to...

Xanthoceras sorbifolia Bunge. is used in traditional medicine in North China. To evaluate the anti-tumor and radical-scavenging activities of X. sorbifolia husks polyphenols and determine their structure-activity relationships, 37 polyphenols 1-37 were obtained by bioassay-guided fractionation. Two new compounds 1-2, and compounds 5, 6, 8, 9, 11, 14-17, 21-25, 27-29, 31, 33, 34, 36, and 37 were...

Biochar is a carbon-rich material produced during organic waste pyrolysis. In this context, two experiments were performed to evaluate the effect of biochar from rice husks and cattle manure on soil fertility common bean production, as well identify optimal dose be applied. The first experiment (Experiment I) was conducted according completely randomized design (factorial scheme 2 × + 1) with s...

Abstract The essence of morphological design has been a fascinating scientific problem with regard to understanding biological mineralization. Particularly shaped amorphous silicas (plant opals) play an important role in the vital activity rice plants. Although various organic matters are associated silica accumulation, their detailed functions shape-controlled mineralization process have not s...

Entomopathogenic fungi (EPF) can be an eco-friendly alternative to control pests. To produce large-scale EPF requires underused economical substrates containing high carbon and nitrogen; hence the production could cost-effective. This study investigates effects of organic agricultural waste, i.e., rice bran, husks, tea dregs, wheat bran enriched with cricket powder as culture media on mycelial ...

The increasing demand for energy causes the depletion of fuel fossil. To overcome this, it is necessary to utilize biomass and waste. purpose this study was simulate effect bio-pellet density on temperature, rate pressure combustion made from a mixture gelam wood rice husk. method uses ANSYS simulation with literature review. results showed that composition husks had an decreasing rate, due cal...

The article aims to develop a technology for producing modern fuel briquette from rice husks (RH), which can be used in complex, gives little flame, and does not emit toxic substances during combustion. possibility of using such briquettes is heating cooking on the street unequipped places. Consumers military units combat operations or exercises, expeditions, tourists working areas where stable...
