Drought Stress and Corn Silage Quality: Is it Just a Matter of Rainfalls?

چکیده
When I request a memory from 2012 to dairy farmers, almost unanimously they respond “drought stress.” According to the US Department of Agriculture (USDA, 2013), the spring and summer drought of 2012 will be remembered as one of the “worst agricultural calamities” in the United States (USDA, 2013). The drought of 2012 reduced the national corn grain and silage yields by 16.2 and 16.3%, respectively, when compared to 2011 (USDA, 2013). These reductions incurred in more than $1 billion in additional feed expenses to the dairy industry.

Effect of drought stress and application of clinoptilolite on yield and quality of silage corn hybrids
Present study was carried out to evaluate the effects of drought stress and clinoptilolite on the yield and forage quality of silage corn hybrids. The experiment was arranged in a three-replicated split-spilt plot based on randomized complete blocks design (RCBD) with three irrigation regimes including optimum irrigation, moderate and severe drought stress (irrigation after 70, 100 and 130 mm e...
متن کاملEnvironmental Factors Affecting Corn Quality for Silage Production
Corn silage is a major ingredient of diets for dairy cattle. Environmental factors can affect the yield and composition of corn silage. Drought and heat are two common environmental factors that affect silage yield and quality. Corn silages with low concentrations of dry matter, high concentrations of protein, high concentrations of fiber, and low concentrations of starch indicate that the crop...

Extended Abstract Introduction and Objective: To overcome the problems caused by animal feed shortages, efforts are made to increase the availability of nutrients and their digestibility, such as improving the nutritional value of forage plants through biological processing. Schizophyllum commune is an edible fungus of the basidiomycete’s family that has been used for biological processing of ...
متن کاملSilage Evaluation of Tropical Corn in a Starter-minimum Tillage System
The greatest economic value from a corn (Zea mays L.) crop is obtained when it can be used as silage rather than for grain only. The objectives were to study tropical corn silage yield and quality in relation to starter fertilizer, planting date, corn hybrid, and fall armyworm stress. This study was conducted in the field a t Quincy and Jay, Florida during 1991 and 1992. Results have shown the ...
