Ozone pollution is damaging wheat, rice and maize crops across China, South Korea and Japan to the tune of $63 billion (£46 billion) each year. Surprisingly, they found that chronic ozone stress caused a 25% decrease in yield in the hybrid crops while the inbred plants remained unaffected. We propose an inductive approach to determine a pathway towards increasing gender-responsiveness within maize breeding. All. 2015. A land process model, Integrated Science Assessment Model, is extended to simulate contemporary soybean and maize crop yields accurately and changes in yields over the period 1901-2100 driven by environmental factors (atmospheric CO 2 level ([CO 2]) and climate), and management factors (nitrogen input and irrigation).Over the twentieth century, each factor contributes to global yield . Google Scholar provides a simple way to broadly search for scholarly literature. The genetic basis of maize RSA is poorly understood, and the maize RSA-related genes that have been cloned are very limited. In order to solve the problem of accuracy and speed of disease identification in real-time spraying operation in maize field, an improved ResNet50 maize disease identification model was proposed. It is very sensitive to salt, heat, drought, cold and heavy metal stresses. Show more. What is less well appreciated is the story of its remarkable transformation ().Genetic data point to the tropical Balsas river valley in Mexico as the site where maize (Zea mays ssp. Effects of conservation agriculture on crop and system productivity and profitability under maize based system in far western Nepal Glutaredoxins are small redox proteins that use glutathione as a cofactor.

In an effort to increase genetic gains and avoid the laborious tasks of conventional breeding, the use of marker-assisted selection or genomic selection programs was proposed. The Global Maize project is an interdisciplinary, international research effort with an overall objective of creating local, ecological intensification (EI) practices for maize production that increase yields at a faster pace than current farmer practices. Maize (Zea mays L.) is an important cereal crop and grown widely across the world (Paudyal et al., Reference Paudyal, Opit, Osekre, Arthur, Bingham, Payton, Danso, Manu and Nsiah 2017a).Besides being a staple food crop in sub-Saharan Africa, maize is also used for industrial purposes and animal feed (Nwosu, Reference Nwosu 2018).However, a substantial amount of maize grain is . High fertilizer prices will likely lead to a decline in application rates as 63 percent of farmers reported reduced input use, which will negatively affect yields. Nitrogen is the macro-nutrient that most frequently limits the growth and productivity of non-leguminous plants (Schepers et al., 1992) and is the most limiting factor in maize production (McCarty and Meisinger, 1997).A number of diazotrophic bacteria were previously found . Search across a wide variety of disciplines and sources: articles, theses, books, abstracts and court opinions. Systematic and in-depth research on these issues will provide new pathways to comprehensively understand the bacterial community in the maize rhizome and to identify measures to improve corn yield and quality. Galactosides in a variety of forms, including raffinose, partially repressed the sucrose-induced accumulation of transcript in heat-stressed callus. The pathogen is an obligate biotrophic parasite that is difficult to culture on artificial media. From 2012 to 2021, MAIZE has focused on doubling .
