This study evaluates both the profitability and risk efficiency of grazing stocker steers on conservation tillage winter wheat pasture using simulation and stochastic efficiency with respect to a function (SERF). Average daily gains are simulated for steers grazed on conventional tillage (CT),...

According to the many years of research results in a stationary field experiment on southern chernozems, it has been shown that the systematic use of fertilizers for black and green fallow provides the production of winter wheat grains with protein and gluten that meets the requirements of the...

In the southern Great Plains of the United States, winter wheat is a dual purpose crop that produces forage for livestock grazing in the fall and winter, and a grain crop in the spring. Seasonal and interannual climate variations are pronounced and make it difficult to anticipate forage...

According to the many years of research results in a stationary field experiment on southern chernozems, it has been shown that the systematic use of fertilizers for black and green fallow provides the production of winter wheat grains with protein and gluten that meets the requirements of the...

Topic Relevance Foliar diseases often reduce grain yields of winter wheat in the southern Great Plains, with some individual year yield losses in excess of 10%. At current prices, the gross value of these losses for the region could exceed a quarter of a billion dollars annually. Historically,...

In the process of analysis of agricultural and weather factors influence on winter wheat yields it was revealed that the critical factors for the yield formation are (totally in Ukraine): the quantity of days with temperatures below 17 degrees of frost Celcius; the quantity and intensity of...

The information presented in this report represents data collected from farming and ranching operations in the southern two tiers of counties in Nebraska. This study was based on a random sample of 151 southern Nebraska farms that have annually-planted crop acreage. Information was obtained for...

Interactions among the nitrogen (N) fertilization rate, N source, and disease severity can affect mean yield and yield in conservation tillage wheat production. A Just-Pope model was used to evaluate the effects of N rate, N source, and disease on the spring N fertilization decision. Ammonium...

A model that integrates biophysical simulations in an economic model is used to analyze the impact of climate change on crop production. The biophysical model simulates future plant-management-climate relationships and the economic model simulates farmers’ adaptation actions to climate change...
