Ninety crossbred beef calves (277.7 ± 7.1 kg) were utilized in a completely randomized design to determine supplement and rumen undegraded protein (RUP) influence on calf performance while grazing stockpiled tall fescue. Calves were supplemented at 1.15% of BW DM with dried distillers grains w/solubles (DDGS); 80.7% DDGS, 19.3% AminoPlus (DDG19); 80.7% soybean hulls (SBH), 19.3% AminoPlus (SBH1...
In order to maintain sustainable agriculture and prevent excessive use of chemical fertilizers, supplying part of the plant needs by organic fertilizers is necessary. In this respect, effects of nitrogen (N) source and rate on yield and yield components of forage sorghum was evaluated as a factorial experiment arranged in randomized complete blocks design with three replications at the Research...
Effects of different levels of nitrogen fertilizer and cutting time of forage on grain and forage yield of barley (Hordeum vulgare L.) Karoon cultivar was studied during 1995-1996 at Ramin Agricultural Research and Educational Center, University of Shahid Chamran, Ahwas, by using a split plot design in randomized complete block with 4 replications. Main plots were assigned to five levels of N f...
Abstract In pasture-based dairy production systems, identifying the appropriate stocking rate (SR; cows/ha) based on farm grass growth is a key strategic decision for driving overall business. This paper investigates number of scenarios examining effects SR (2–3 cows/ha (0.25 unit changes)), annual nitrogen (N) fertilizer application rates (0–300 kg N/ha (50 kg/ha soil type (heavy and free-drai...
In order to evaluate the effect of different amounts of nitrogen fertilizer, potassium sulfate, magnesium sulfate and zinc sulfate on biodiesel produced from safflower, a field experiment was carried out as completely randomized blocks design with three replications, at Research Farm of Shahrekord University in 2010. Treatments included nitrogen fertilizer at three levels (150, 200 and 300 kg/h...
Biosolids are utilized as nutrient rich fertilizer. Little material is available on benefits to forage crops resulting from fertilization with biosolids. This paper aimed to compare the effects of fertilization with biosolids versus commercial nitrogen fertilizer on growth, root formation, and nutrient value of triticale plants in a greenhouse experiment. Per treatment, five pots were seeded wi...
extinction coefficient (k) is an important index that shows the rate of light decrease in canopy. net biomass accumulation is linearly related to cummulative light interception. the slope of this relationship is termed radiation use efficiency. a split plot experiment within randomized complete block design with three replications was conducted in april 2001 in sugar beet research station in ka...
Selenium (Se) was applied to perennial ryegrass (Lolium perenne) and subterranean clover (Trifolium subterranean) pasture as a fertilizer to determine the effect of Se form and concentration on Se accumulation in subsequent forage growth. Treatments were a no Se control, 0.6 kg/ ha Se as sodium selenate, and 0.6, 1.1, and 2.2 kg/ha Se as sodium selenite, all applied to pasture plots with low so...
spp.) showed that forage DM intake was positively correlated with N fertilization rate. Fertilization may also Because native, shortgrass prairies are not typically fertilized and increase forage preference by livestock. Cook and Jeffotherwise extensively managed, little information is available on their response to nitrogen (N) fertilization. An experiment was conducted eries (1963) showed tha...
a field experiment was conducted in order to study the effect of nitrogen fertilizer and plant density on yield and quality of maize (zea mays l.) cultivar, mv500 silage as second crop. this study was conducted in agricultural research station of kurdistan university during 2012 growing season. the experiment was laid out as split plot based on randomized complete block design with three replic...
