In the United States, losses in crop production due to drought and flooding accounted for more than 70% of the yield reductions in 2011, and the frequency of these climate extremes is increasing in farming regions (Bailey-Serres et al., 2012). Incidence of excessive rainfall events in the Midwest region has increased over 30% from 1958 to 2007 and is expected to increase more in the future, esp...
In order to find suitable cultivar and N-topdress rates in corn planted after wheat harvest, a field experiment was conducted in Isfahan University of Technology Experiment Farm located at Shervedan, Falavarjan in 1994. The experiment design was a split plot with a randomized complete block arrangement and four replications. Main plots were four N-topdress rates (0, 90, 180, and 270 kg/ha) and ...
Unfavorable storage conditions, especially relatively high environment humidity and high storage temperature greatly affect the quality of corn seeds. The effects of temperature, environment moisture and length of storage on six maize hybrids were examined. For the purpose of investigating germination traits, total soluble proteins, leakage electrolytes and the activity of antioxidant enzymes i...
Delay of sowing date in subtropical environments with long growing seasons can modify the yield response corn hybrids to nitrogen (N) fertilization. This study evaluated effects time, and N top-dress rate on hybrids’ N-use efficiency different cycles. Two field experiments were carried out environment southern Brazil. The following factors investigated: (AG9025, super early cycle P30F53, cycle)...
A genetically modified corn hybrid homozygous for the lpa1 allele, containing low phytate (LP), and its nearly isogenic equivalent hybrid (normal) were compared in two experiments with growing-finishing swine. In Exp. 1, 210 barrows (27 kg) were allotted to one of six dietary treatments with two corn hybrids (LP and normal) and three P feeding regimens. There were five replicate pens (seven pig...
The objective of this work was to evaluate the potential corn hybrids for grain productivity and fresh produce marketability in two crop seasons. experiment applied completely randomized block design with three replications, during 2013-14 2014-15 crops. Ten indicated Midwest region Goiás state were used, namely 2B512PW, 2B587PW, 2B707PW, 30F35HR, 30F53YH, BRS1055, BM3061, P3646H P3862YH. Hybri...
The northern and western corn rootworm (Coleoptera:Chrysomelidae) are major pests of corn (Zea mays L). The development of Bt corn, corn that has been genetically modified to produce toxins from Bacillus thuringiensis, has been valuable in controlling the damage these pests can inflict on a grower’s corn. With the large acreage being planting to Bt corn especially in the Midwest, there has been...
Corn flea beetles, Chaetocnema pulicaria, vector Erwinia stewartii (synamorph Pantoea stewartii), which causes Stewart’s bacterial wilt of corn (Zea mays) (10,11). Flea beetles introduce E. stewartii into plant tissues that are wounded during feeding. Movement of E. stewartii in the vascular system of resistant plants is restricted to within a few centimeters of flea beetle feeding wounds. The ...
