Understanding ecophysiological characteristics of corn (Zea mays L.) under winter cover crops (WCCs) can improve management and farmers’ acceptance by increasing the positive effects and decreasing the negative effects associated with their use. This study was conducted to quantify the effects of WCC on corn development, growth, and yield through the evaluation of ecophysiological characteristi...

Although cover crops are typically terminated 2–4 weeks prior to cash crop planting, there may be situations where late-burndown or planting into a living (planting green) necessary even beneficial. This experiment investigated the effect of termination date on corn (Zea mays) yield and presence beneficial insects. Three different dates were tested: 4 (brown), 7 14 days (green-brown), at (green...

The potential benefits of transgenic rootworm corn (Cry3Bb1 protein) are expected to include: increased root protection; increased intangible benefits to farmers (safety of not being exposed to insecticides, ease of use and handling, time and labor savings, better pest control); increased economic benefits to farmers ($231 million from yield gains [$25-$75/acre relative to no insecticide contro...

The objective of this study was to evaluate the effects corn-planting population, using two conventional (Conv) and brown-midrib (BMR) hybrids, maturity stage at harvest on forage dry-matter (DM) yield, silage quality, in-vitro fiber digestibility. conducted in fields with contrasting production potential, where both corn hybrids were planted a theoretical planting population 59,000, 79,000, 99...

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...

Prevention, rather than cure, is the rule with the diseases of peanuts. Some beneficial preventive measures are the application of fungicides to seed to prevent seed rot, the use of fungicidal dusts or sprays on grovv^ing plants to prevent leaf spot, and the treatment of soil with chemicals before planting to control nematodes and soil insects. Prevention involves more than the use of chemicals...

Cover crop growing periods in the western U.S. Corn Belt could be extended by planting earlier. We evaluated both pre-harvest broadcast interseeding and post-harvest drilling of following cover crops: (a) cereal rye (Secale cereale L.) [RYE]; (b) a mix + legumes brassicas [MIX1], (c) oat [Avena sativa L.] (MIX2), (d) [LEGU]) (e) no control. These were tested continuous corn (Zea mays [corn–corn...

in order to determine the appropriate plant density in different planting dates for sweet corn cultivar ksc403su, an experiment was conducted using a randomized complete block design in split plot lay out with three replications at seed and plant improvement institute in karaj in 2006. three planting dates (22 may, 5 june and 22 june) were assigned as main plots and three plant densities (65000...

Unlike the Central and Eastern U.S. Corn Belt where maize is grown almost entirely under rainfed conditions, maize in the Western Corn Belt is produced under both irrigated (3.2 million ha) and rainfed maize (4.1 million ha) conditions. Simulation modelling, regression, and boundary-function analysis were used to assess constraints to maize productivity in the Western Corn Belt. Aboveground bio...
