Rethinking sources of nitrogen to cereal crops

Genetic transformation of major cereal crops.

Of the more than 50,000 edible plant species in the world, at least 10,000 species are cereal grains. Three major cereal crops, rice (Oryza sativa), maize (Zea mays), and wheat (Triticum sp.), provide two-thirds of the world's food energy intake. Although crop yields have improved tremendously thanks to technological advances in the past 50 years, population increases and climate changes contin...

Relationships of cereal crops and other grasses.

The grass family includes some 10,000 species, and it encompasses tremendous morphological, physiological, ecological, and genetic diversity. The phylogeny of the family is becoming increasingly well understood. There were two major radiations of grasses, an early diversification leading to the subfamilies Pooideae, Bambusoideae, and Oryzoideae, and a later one leading to Panicoideae, Chloridoi...

Biculture Legume–Cereal Cover Crops for Enhanced Biomass Yield and Carbon and Nitrogen

leach into groundwater after crop harvest in the fall, and depending on the species, can sequester atmospheric C Biculture legume–cereal cover cropping may enhance aboveand and/or N, thereby reducing the amount of N fertilizer belowground biomass yields and C and N contents. The increase in C and N supply to the soil has the potential to improve soil quality required for summer crops (Hargrove,...

allocation of premium subsidy to promote productivity in cereal crops

in this study, a model of optimal allocation of subsidy was developed based on the microeconomic optimization theory. the model was evaluated by applying to premium subsidy allocation to the cereal crops’ (corn, rain fed barley and wheat, and irrigated barley and wheat) insurance in iran. in developing the model, it was assumed that, policymaker on behalf of society, follows a social utility ma...
