to study yield and its relationships with yield components in 10 varieties of foxtail millet (kfm1 to kfm10), an experiment was carried out in safiabad agricultural research center in rcbd design with three replications for a period of three years (2003 to 2005). vegetative and reproductive characteristics of each cultivar were recordered during the growing seasons. three year results showed si...

3.5 ha of sweet potato were used to feed 30 crossbred Brahman bulls with an average weight of 184 kg and approximately one year old in an experiment to study the use of sweet potato in beef production. The five treatments were allocated to the experimental units in an unrestricted randomized block design. Treatments contained 0:100, 25:75, 75:25, 50:50 ant 100:0 ratios of tubers to sweet potato...

Selenium (Se) is an essential micronutrient in cattle, and Se-deficiency can affect morbidity and mortality. Calves may have greater Se requirements during periods of stress, such as during the transitional period between weaning and movement to a feedlot. Previously, we showed that feeding Se-fertilized forage increases whole-blood (WB) Se concentrations in mature beef cows. Our current object...

The effects of the proportion of concentrates in grass silage-based diets and of restricted dry matter (DM) intake were examined using 156 Simmental cross Friesian steers which were initially 389 kg live weight. The animals were reared on high-forage diets until 14 months of age and were then given grass silage ad libitum and supplemented with rolled barley which constituted (1) 0, (2) 120, (3)...

Alfalfa losses and quality changes begin as soon as the mower contacts the standing crop and these losses continue until the preserved feed is consumed. Harvest losses are caused by plant respiration, rain, and mechanical damage by equipment. Loss from plant respiration is relatively small when the crop is dried quickly under good drying conditions, but under slow drying conditions it can be up...

A culture system for digesting forages utilizing washed ruminal bacteria was examined. Cultures inoculated with washed bacterial suspensions had similar cellulolytic populations but lower methane production rates than did cultures inoculated with rumen fluid. Subsequent experiments utilized washed cell suspensions. Urea supplementation (8 mM) increased total bacterial and cellulolytic populatio...

KUSLU, Y., U. SAHIN, T. TUNC and F. M. KIZILOGLU, 2010. Determining water-yield relationship, water use efficiency, seasonal crop and pan coefficients for alfalfa in a semiarid region with high altitude. Bulg. J. Agric. Sci., 16: 482-492 A field study was conducted to determine effects of seasonal deficit irrigation on plant dry forage yield and water use efficiency of alfalfa for a 2-year peri...

Fenugreek (Trigonella foenum-graecum L.) is used as medicinal plant in many Asian countries and has been reported to have forage quality similar to alfalfa. Fenugreek is an annual crop and may have the potential to diversify forage production systems in the central High Plains. This study evaluated forage dry matter (DM) production and the nutritive value of three fenugreek cultivars as influen...

Various species and varieties of brassicas were evaluated for their potential to extend the grazing season and provide forage through late-fall and early winter in Colorado. The species and varieties evaluated included: rapes (Bonar, Winfred, and Barnopoli), turnips (Appin, Barkant, and Purple Top), kale (Kestral), turnip x rape hybrid (Pasja), swede (Major Plus), and radish (Groundhog). Each s...
