The effects of cropping systems (fallow, rotation with sorghum-sudangrass hybrid [Sorghum bicolor x S. sudanense], and continuous soybean [Glycine max]), nematicide (aldicarb) treatment, and soybean cultivar on yield and nematode population densities were studied in a field infested with a mixture of Meloidogyne spp. and Heterodera glycines. Soybean following sorghum-sudangrass yielded 111 kg/h...

a complete diet (total mixed ration) with sorghum stover (40%) as sole roughage source was prepared and offered to animals under two forms: as mash or as expanded-extruded pellets (eep). these two complete diets were compared with a conventional diet (ad libitum chopped sorghum stover fed separately with concentrate mixture to meet 80% of protein requirements). these three diets were randomly a...

in order to study the effects of mechanical and chemical methods of weed control and their interaction on cotton (cv. varamin) an experiment was conducted in agricultural research field, the university of birjand during 2008 growing season using a randomize complete block design with 12 treatments and 4 replications. treatments were: trefelan (trifluralin 48% ec) 960cc ai ha-1 (pre-plant), sona...

Meloidogyne chitwoodi race 1 reproduced on Piper sudangrass (Sorghum bicolor (L.) Moench), 332 (sudangrass hybrid), and P855F and P877F (sorghum-sudangrass hybrids), but failed to reproduce efficiently on Trudan 8, Trudex 9 (sudangrass hybrids), and Sordan 79, SS-222, and Bravo II (sorghum-sudangrass hybrids). Meloidogyne chitwoodi race 2 behaved similarly and reproduced more efficiently on Pip...

Annual and perennial habit are two major strategies by which grasses adapt to seasonal environmental change, and these distinguish cultivated cereals from their wild relatives. Rhizomatousness, a key trait contributing to perenniality, was investigated by using an F(2) population from a cross between cultivated rice (Oryza sativa) and its wild relative, Oryza longistaminata. Molecular mapping b...

The objective of this work was to produce an herbicide by submerged fermentation in a stirred-tank bioreactor and to assess the potential herbicidal in pre-emergence, post-emergence, and in a detached leaves of Cucumis sativus var species. wisconsin (cucumber) and Sorghum bicolor (sorghum) species. Fermentations were carried out in a stirred-tank bioreactor with useful volume of 3L. Stirring ra...

Parthenium weed (Parthenium hysterophorus L.) is an internationally important invasive native to the tropical and sub-tropical Americas, in more than 30 countries. This has serious adverse influences on rangeland agricultural crop production, human animal health, biodiversity of natural communities. leaf litter can reduce seedling emergence affect early growth a wide range pasture species. Soil...

The host suitability of five of the most common weed species occurring in maize (Zea mays L.) fields in South Africa to Pratylenchus zeae was tested. Based on the number of nematodes per root unit, mealie crotalaria (Crotalaria sphaerocarpa) was a good host; goose grass (Eleusine indica), common pigweed (Amaranthus hybridus), and thorn apple (Datura stramonium) were moderate hosts; and khaki we...

striga hermonthica is a parasitic weed which largely constrains maize and sorghum production in western kenya. the weed mostly invades small scale farms and depending on severity, it may cause damage ranging from 10% to complete crop failure thereby aggravating the food insecurity in that region. this study aimed at evaluating fungal isolates as possible biocontrol agents against the weed. fung...

Cereal Chem. 73(6):744-750 Lesser grain borer (Rhyzopertha dominica), red flour beetle (Tribolium flour beetle caused some off-odor. The other three insects caused little or castaneum), rice weevil (Sitophilus oryzae), saw-toothed grain beetle no objectionable odor, even though infestation was heavy. High concen(Oryzaephilus surinamensis), and rusty grain beetle (Cryptolestes fertrations of 2-p...
