Predictions of yield for the globe's major grain and legume arable crops suggest that, with a moderate temperature increase, production may increase in the temperate zone, but decline in the tropics. In total, global food supply may show little change. This security comes from inclusion of the direct effect of rising carbon dioxide (CO2) concentration, [CO2], which significantly stimulates yiel...

Without new innovations, present rates of increase in yields of food crops globally are inadequate to meet the projected rising food demand for 2050 and beyond. A prevailing response of crops to rising [CO2 ] is an increase in leaf area. This is especially marked in soybean, the world's fourth largest food crop in terms of seed production, and the most important vegetable protein source. Is thi...

Predation is often a key factor maintaining insect populations below pest status in annual crops. However, in many cases, the predators causing significant mortality to particular pests in the field are not well understood. In particular, the complex of nocturnally active predators feeding on pest species is usually unknown. The predator complexes attacking lepidopteran eggs in cotton, corn and...

the study carried out an assessment of agricultural land management practices in food crops production among small scale farmers in kwara sate, nigeria. specifically, the study determined the socio economic characteristics of crop farmers in kwara state; ascertained the cropping patterns common among them; highlighted the soil conservation methods adopted by the farmers; examined the relationsh...

In rats, feeding can be triggered experimentally using many approaches. Included among these are (1) food deprivation and (2) acute microinjection of the neurotransmitter l-glutamate (Glu) or its receptor agonist NMDA into the lateral hypothalamic area (LHA). Under both paradigms, the NMDA receptor (NMDA-R) within the LHA appears critically involved in transferring signals encoded by Glu to sti...

The deep-sea benthic community at the Porcupine Abyssal Plain (NE Atlantic) is a highly food limited system. The annual input of sedimenting phytodetritus, which reaches the sea floor around May/June, is the major input of energy. The relative trophic position of the most abundant components of the benthos (90 species or higher taxonomic groups), including meiofaunal, macrofaunal, and megafauna...

Can public policies and research institutions in African countries provide safe and useful genetically modified (GM) food crops? This is an urgent question, recognizing that advancing GM food crops can be difficult, affected by global debate, and various regulatory protocols. Reaching farmers has been achieved in several countries only for GM cotton for insect resistant while approvals for food...

World population is expected to reach 9.2 × 10(9) people by 2050. Feeding them will require a boost in crop productivity using innovative approaches. Current agricultural production is very dependent on large amounts of inputs and water availability is a major limiting factor. In addition, the loss of genetic diversity and the threat of climate change make a change of paradigm in plant breeding...
