Limited availability of herbage during the cool season creates a problem of a supply of nutrients for livestock producers throughout the southern Great Plains of the USA and, particularly, on small farms where resource constraints limit possible mitigating strategies. Six coolseason grasses were individually sown into clean-tilled ground, no-till drilled into stubble of Korean lespedeza [Kummer...

Transpiration, as one of the components of hydrological cycle, has not been paid enough attention yet, while it is necessary for sound utilization of rangelands, mostly located in the arid and semiarid regions. The comparison of the different kinds of rangelands species in terms of transpiration rates provides range managers the required information to achieve optimal forage production for a gi...

We examined suitability of arbuscular mycorrhizal fungi (AMF) associated with cool-season nonnative forages on reclaimed surface-mined land in southeast Ohio for establishment of native warm-season grasses. The goal of establishing these grasses is to diversify a post-reclamation landscape that is incapable of supporting native forest species. A 16-week glasshouse study compared AMF from a 30-y...

The objective of this research was to study the effects of phenological stages on yield and quality traits in 22 populations of tall wheatgrass Agropyron elongatum. A split plot design was conducted using a complete randomized block with two replications in Lorestan (Borujerd), Iran during 2007-2008. The genotypes were cut in five maturity stages as vegetation, stem elongation, heading date, an...

Cultivation of energy crops is a part modern agriculture. In particular, maize (Zea mays L.) widely grown in central Europe. However, terms erosion risk and high demands on fertilization protection against diseases pests, its growing not environmentally friendly. Therefore, possibilities utilization other more friendly have been examined at present. The aim the study was to evaluate effects var...

An experiment was conducted to determine the effect of roughages on the utilization of dietary nitrogen, energy and fiber by gravid swine. Water consumption, backfat depletion, pregnancy weight gain, and reproductive performance were used as response criteria. Metabolism assays, employing 18 crossbred sows (second or third parity), were initiated at days 0 (prior to breeding), 30 and 80 postcoi...

A significant portion of the irrigated acreage in the intermountain western U.S. is comprised of cool season grass pastures. Droughts, coupled with increasing demands for limited water supplies in the region, have decreased the water volumes available for irrigating these pastures and other crops. Consequently, relationship between crop yield and irrigation (water production functions) should b...

In the tribe Triticeae, several Thinopyrum species have been used as sources of resistance to stem rust (caused by Puccinia graminis Pers.:Pers. f. sp. tritici Eriks. & E. Henn., abbreviated as Pgt) and other wheat (Triticum aestivum L.) diseases. To identify novel sources of resistance to Pgt race TTKSK (Ug99), we evaluated and characterized the stem rust resistance of 242 accessions belonging...
