The graminous host range and sources of sorghum [Sorghum bicolor (L.) Moench.] plant resistance, including cross-resistance from greenbug, Schizaphis graminum (Rondani), were studied for the newly emerging sugarcane aphid, Melanaphis sacchari (Zehntner), in greenhouse no-choice experiments and field evaluations. The sugarcane aphid could not survive on field corn, Zea mays (L.), Teff grass, Era...

New cultivars of sorghum are being developed for increased food use, as livestock feed, and for the bioenergy industry by manipulation of secondary metabolic pathways through breeding. Previous work has suggested that such modifications may have an impact on cultivar response to fungal pathogens. We investigated four inoculation strategies that may be used in studies involving pathogens of sorg...

The host efficiencies of corn, sorghum, soybean, and wheat were compared for a Kansas population of Belonolaimus sp. under greenhouse conditions. In a related field study conducted in 1989 and 1990, the responses of Belonolaimus sp. and Pratylenchus scribneri populations to eight cropping regimes were monitored at depths of 0-30 and 31-60 cm in sandy soil. With the exception of alfalfa, all cro...

Southern rootworm (Diabrotica undecimpunctata howardi) affects several plants such as soybean, sorghum, wheat, cucumber, alfalfa, cucurbits and it is most damaging to corn and peanuts. The pheromone based “attract and kill” strategy is one of the powerful ways to control pest population. To address our key objective of the practical utility of the synthetic pheromone, we have developed a simple...

A calibrated SWAT model equipped with an improved auto-irrigation function was used to evaluate the impacts of agricultural production practices on water balances and crop yields corn, sorghum, winter wheat for Palo Duro watershed located in Texas High Plains (THP). Fourteen scenarios were simulated including alternative irrigation application depths 12.7 mm 38.1 irrigated different planting da...

In our country there are a lot of surfaces with sandy soils and high concentration salts, but the lack some productive free tannin made that this plant to be less used than corn. The macro-elements consumption at sorghum culture, in natural conditions is level P70N80-100, appliance Phosphorous under work soil Nitrogen preparation germinative bed disk.

Annually between 1994 and 1998 over 400,000 acres of grain sorghum have been harvested in Missouri with an average yield of 86/bushels/acre. The average value of production during this period was over $90 million. Grain sorghum (milo) is an important crop for some Missouri producers. Many sorghum producers also produce corn, soybean, or wheat. Each of these commodities has an actively traded fu...

In recent years, there has been a growing interest in brown midrib (BMR) sorghum (Sorghum bicolor (L.) Moench.) · sudangrass (Sorghum sudanense Piper) hybrids (SxS) as a replacement for silage corn (Zea mays L.) in the north-eastern USA. Recent studies suggest it is suitable for both rotational grazing and as a hay crop and could compete with corn harvested for silage in years when wet spring c...
