In this study, the optimum irrigation depths for corn grain production under different conditions, i.e. maximum grain yield production and maximum benefit under limited land and water conditions, were determined under sprinkler irrigation in Bajgah (15 km. north of Shiraz). The results showed that, the optimum depth of irrigation for maximum grain yield production was 77.0 cm. Because of low pr...

In recent years, food security, especially supply, has been an important issue in China’s agricultural production. The stability of grain prices is related to the stability and development of the grain market. Based on agricultural production data from 1970 to 2015, this paper explores the influence of agricultural product price fluctuation on grain production by using the cobweb theory and vec...

In 18F micro-autoradiography using a frozen section method, the grain production was measured relative to the exposure time and radioactivity. The grain production increased until 6-hr exposure, but 7-hr or longer exposure induced a characteristic of latent image fading. However, the ratios of the efficiency of grain production between two different 18F-radioactivities (11.9 and 2.3 mBq/100 mic...

The objectives of this study were to partition corn grain into three digestible fractions and to measure the rate of disappearance of these fractions in vitro. Seventeen corn grain samples with varied fiber concentrations were extracted with either 80% ethanol or neutral detergent to obtain estimates of the pool size and digestion kinetics of the A, B1, B2, and C fractions. The carbohydrate sol...

Desirable grain quality attributes vary depending upon the intended end use of grain. Environment, production practices and genetics are all of importance. Nutritional value of grain is most important for animal feed. Dry mill and alkaline cooked products require hard kernels with low breakage susceptibility and high protein concentration. Grain for these uses would best be produced under dryla...

The article provides a conceptual analysis of the concept of "mechanism", considers the scientific aspects of economic mechanisms that stimulate the grain production development with the use of innovations. The development of grain production in the country needs strengthening the organizational and economic processes that are in constant improvement of scientific and technological base of grai...

Renewable fuel production, particularly grain-based ethanol, is expanding rapidly in the USA. Although subsidized grain-based ethanol may provide a competitively priced transportation fuel, concerns exist about potential environmental impacts. This contribution focuses on potential water quality implications of expanded grain-based ethanol production and potential impacts of perennial-grass-bas...

The effect of nitrogen fertilization of maize on fermentability of maize grain in the rumen was studied by means of in vitro method based on the measurement of gas produced during the incubation of samples with rumen liquor. Gas production was recorded continuously up to 72 h incubation time and cumulative gas production was described by the Gompertz equation Y=A*exp(-exp(-d*(t-tm))). Seven tre...
