Corn producers battle a variety of soil dwelling insect pests. Seedcorn maggots, wireworms, white grubs and several species of cutworms can attack either the seed or seedling plants and reduce the plant stand. Corn rootworm larvae feed on corn roots during midsummer and can significantly reduce the uptake of moisture and nutrients. Extensive feeding by corn rootworm larvae can reduce the roots ...
In this study, it was possible to evaluate the production of polyhydroxyalkanoates (PHAs) from microalgae Chlorella vulgaris and Tetradesmus obliquus, using 1% 0.25% (v/v) agro-indusytial Corn Steep Liquor residue, a product corn processing. The biomass subjected mechanical extraction 4% sodium hypochlorite + chloroform, extract further characterized Fourier Transform Infrared Spectroscopy (FTI...
One grazing and two feeding experiments were conducted to compare the feeding value of corn grain, corn silage, or corn residue from a second generation insect protected (Bt) hybrid (MON 89034) developed by Monsanto including two proteins (Cry1A.105 and Cry2Ab2) with a non-transgenic parental hybrid (PAR), and two commercially available non-transgenic reference hybrids (REF1 and REF2). Diets fo...
The effects of cotton-corn rotation and glyphosate use on levels of soil-borne Aspergillus flavus, aflatoxin and fumonisin contamination in corn and cotton seed were determined during 2002-2005 in Stoneville, Mississippi (USA). There were four rotation systems (continuous cotton, continuous corn, cotton-corn and corn-cotton) for both glyphosate-resistant (GR) and non-GR cultivars-herbicide syst...
Key planting factors that influence corn stand establishment includes uniform depth and spacing of seed, correct seed population and optimizing the soil environment for rapid germination and uniform emergence. Other variables affecting stand establishment are seedbed quality (including soil moisture and temperature), seed quality and planter speed. Differences among fields for stand establishme...
the effects of soil tillage methods and residue management were studied at miandoab agriculure station during 2003-2005. the experiment design was split block with the main plots devoted to residual management strategies (burning residue, crushing residue by disk, no treatment). subplots were tillage methods (moldboard plowing to 20-25 cm in fall, moldboard plowing to 20-25 cm in spring, moldbo...
Seed from maize (corn) Zea mays provides a ready source of 9-lipoxygenase that oxidizes linoleic acid and Iinolenic acid into 9(5)-hydroperoxy-1 0(8, 12(Zl-octadecadienoic acid and 9(SJ-hydroperoxy-1 0(£), 12(Zj, 15(Zl-octadecatrienoic acid, respectively. Corn seed has a very active hydroperoxide-decomposing enzyme, allene oxide synthase (AOS), which must be removed prior to oxidizing the fatty...
Field experiments were conducted during 2017 and 2018 to evaluate the efficacy of herbicides NICOSULFURON and EPTC alone or in combination with seed priming on weed control and corn yield. NICOSULFURON (80 g a.i. ha‒1) was applied at four- to six-leaf stage of corn as post-emergence and EPTC (4920 g a.i. ha‒1) applied as pre-plant incorporation (PPI). Among the herbicide treatments, the lowest ...
Corn production management including nitrogen consumption will be different at different circumstances. In order to investigate the effect of different levels of nitrogen fertilizer on yield and yield components of seed corn hybrids in Khuzestan weather conditions, this research was carried out in the summer of 2013 in the lands of Safi Abad Agriculture and Natural Resources Research Center-Dez...
