Grain production and utilization in Russia and the USSR before collectivisation
… concerned with analysing the available data on grain production and its utilisation from the time when the earliest grain statistics became available in pre-revolutionary Russia until the eve of mass transformation of Soviet agriculture that was associated with mass collectivisation in 1929. The …

A Descriptive Study of Grain Production, Consumption, and Storage in Virginia
… respectively, in 2012. One of the products, grain, serves as an important input for raising livestock and poultry. Virginia needs to import grain from other states (Eastern Corn Belt states) to meet current livestock feed requirements, an expense that raises the cost of production over …

Energetics of low-input corn production
… costs associated with nitrogen-fixing legume production and use. The energetics of com silage and com grain production under standard and alternative practices are examined. Economic analyses of crop production practices are used to aid the selection of recommended alternative practices. In …

Alternative and Improved Cropping Systems for Virginia
Feed grain consumption in Virginia and the mid-Atlantic region is more than double the total production. Producing more feed grains in this region could generate more profit for grain growers and lower costs for end-users. Increased feed grain production in this region will necessitate improved …

The sustainability of tropical maize as an alternative biofuel or silage crop
… delayed flowering that reduces or eliminates grain production. The reduced grain production results in accumulation of sucrose in the stalk and a lower nitrogen fertilizer requirement. Our objective was to evaluate the impact of sustainable practices such as conservation tillage, cover crops, …

Characteristics of pre-rigor processed beef
"During the last 25 years, the total production of beef and beef products in the U.S. has markedly increased. Most of this increase has been in the form of ground beef and ground beef products (Sink, 1980). In 1970, 20 percent of the beef consumption was in the ground form, while in 1979 this …

The effect of available resources on the forage-grain feeding ratios and forage production systems on selected Virginia grade A dairy farms
… consideration to various ways of reducing their production costs. Feed costs make up 50 to 60 percent of the total cost of producing milk. Consequently, the feeding program on any dairy farm greatly affects the cost of producing milk and, ultimately, the net return to the farmer. This study had …

Distillers grains and the livestock industry in western Canada
… considerations. For a region with substantial grain production, increased prices from additional demand by the biofuel industry may inure to the benefit of grain farmers and land owners in the long term. The livestock industry however remains in a complex position facing the possibility of …

Evaluation of Soil Fertility and Performance of Maize(Zea Mays L.)in Small Holders Maize Farms in Namtumbo District, Ruvuma Region.
… the major soil fertility constrains for maize production were N, P, K and Zn. The fertilizer combination of N120 P40K80 Zn10 was the best combination for all varieties in both sites which increased grain yield from 0.5 t ha-1 in the control treatment to 8.91t ha-1 at Namabengo site and from …

A study of food insecurity and rural development in the Gambia: the impact of rural weekly markets (Lumos)
… and North Bank divisions, where agricultural production of various crops and livestock has improved the livelihood of those rural communities. At the local level, the allocation of a greater proportion of arable land to coarse grain production along with the decline in peanut production hold …

Soil-atmosphere fluxes of CO2 and CH4 in annual and perennial cropping systems in southern Sweden
Annual cropping systems dominate agricultural grain production, but have been linked to several key environmental issues, such as loss of biodiversity and pollution of groundwater. Newly developed perennial grains may offer solutions to some of those problems. Their longer roots and growing seasons …

Genetic dissection of sorghum height and maturity variation using sorghum converted lines and their exotic progenitors
… are photoperiod-insensitive and dwarfed for grain production. Classical segregation studies predict that temperate adaptedness involves four major loci each for maturity and dwarfing. Two major maturity loci, Ma1 (PRR37) and Ma3 (phytochrome B), and a single major dwarfing locus, Dw3 …

Biomass to ethanol : potential production and environmental impacts
… of ethanol produced from three feedstocks; corn grain, corn stover, and switchgrass. A life-cycle assessment approach with an integrated Monte Carlo uncertainty analysis is applied to each of these three bioethanol pathways. Incorporating a Monte Carlo uncertainty analysis within a life-cycle …

Understanding Organic Prices: An Analysis of Organic Price Risk and Premiums
… there is a lack of available U.S.-grown organic grains and soybeans to feed the growing number of organic certified livestock to produce organic meat to meet this demand. This shortage results from many factors, yet is primarily due to organic production requirements for significantly more land …

Impacts of investment in agricultural research on value-added for selected commodity groups
… to the commonly used aggregate output production function approach is to calculate returns based on estimates from a value-added production function. Value added is the value of consumed inputs in the production process subtracted from the value of total production. The value-added …

Make a living: agriculture, industry and commerce in Eastern Hebei, 1870-1937
… By examining the ecosystem and calculating the grain production and consumption, it is found that the returns from farming were not even enough for the peasants own consumption. Eastern Hebei was a grain shortage area and the peasants there had to engage in non-farming activities to supplement …
