crop production in arid and semi arid environments has been affected by drought stress. forage production have important role on animal production in this area. in order to determine the effect of irrigation intervals on the yield and morphological characteristics of forage millet, sorghum and corn, an experiment was conducted in a split plot with a randomized complete block design with four re...

John M. Marsh (406) 994-5621 [email protected] Increases in the demand for cornbased ethanol have contributed to substantially higher corn prices. For example, Central Illinois corn prices increased from $1.84/bushel in the fourth quarter of 2005 to $3.28/bushel in the fourth quarter of 2006, an increase of 78.3 percent (LMIC, 2006). Much of the increase in corn prices occurred during the fall...

This research was conducted to determine the efficacy of quizalofop (FirstAct) herbicide in herbicide-tolerant grain sorghum. FirstAct evaluated for and crop response Double Team (ACCase-tolerant) All herbicides controlled Palmer amaranth 90% or more volunteer corn 95% late season. Johnsongrass control 86 91%. Minor sorghum injury early season did not persist. Sorghum receiving postemergence yi...

Densities of plant-parasitic nematodes were compared on six crops grown for forage during the summer of 1991 at seven sites in north central Florida. The cropping treatments were 'Howard' soybean (Glycine max), 'Deltapine 105' soybean, velvetbean (Mucuna deeringiana), 'California Blackeye #5' cowpea (Vigna unguiculata), 'Pioneer 3098' tropical corn (Zea mays), and 'Asgrow Chaparral' sorghum (So...

to study the root allelopathic effects of cool season crops on germination and early growth of three crops (sorghum, corn, and soybean), an experiment was conducted in seed research laboratory and greenhouse of college of agriculture, university of tehran. the experiment consisted of four cool season crops (wheat, barley, rye and pea) and control as the main plots, three spring-crops (corn, soy...

Crop residues have been considered during the past decade as alternate energy sources to supplement dwindling fossil fuel sources and enhance energy independence in the United States. Agricultural scientists have demonstrated the importance of crop residues in reducing soil erosion, enhancing the soil physical environment for plant growth, and as a reserve for major crop nutrients. In eastern N...

Sweet sorghum [Sorghum bicolor (L.) Moench] is a multipurpose crop (food, feed, fodder and fuel) that has the potential as an alternative biofuel feedstock without impacting food and fodder security. This chapter entitled ‘‘Sweet sorghum: From theory to practice’’ discusses on the historical developments in sweet sorghum and immense range of genetic variability that was available in major sorgh...

Fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), infestations in most of North America north of Mexico arise from annual migrations of populations that overwinter in southern Texas and Florida. A comparison of the cytochrome oxidase I haplotype profiles within the fall armyworm corn-strain, the subgroup that preferentially infests corn (Zea mays L.) and sorghum (Sorg...

Brown midrib (BMR) is a genetic mutation in several grass species. The BMR gene reduces lignin content in plant cell walls and vascular tissue and improves fiber and whole plant digestibility. Lignin is mostly indigestible and plays a critical role in forage quality by affecting digestibility of cell wall polysaccharides. Lignin also plays in important role in plant rigidity. During the past se...

ABSTRACT The aim of this study was to evaluate the effect exogenous amylase on gas production, in vitro dry matter digestibility (IVDMD), and digestion kinetics sorghum (Sorghum vulgaris) two corn hybrids different grain textures. Ruminal fluid collected from rumen-fistulated cows receiving or not (0.7g kg-1 (DM basis)), provided achieve 396 kilo Novo units for activity basis). Gas production m...
