Megjegyzések:	International scientific symposium dedicated to students and young researchers- Oradea, 12 April 2024 Maize (Zea mays L.) is considered the basis for food security in some of the world's poorest regions in Africa, Asia and Latin America and also it is a major component of livestock diet. Globally, 765 million metric tons of maize was harvested in 2010 from just less than 153 million hectares. About 73 percent of this area was located in the developing countries. Maize is currently produced on nearly 100 million hectares in 125 developing countries and is among the three most widely grown crops in 75 of those countries. The crop provides over 20 percent of total calories in human diets in 21 countries, and over 30 percent in 12 countries that are home to a total of more than 310 million people. Soil health and nutrient management present ongoing challenges for sustainable maize production. This study was conducted to review and discuss global challenges facing maize production such as soil erosion, nutrient depletion, and imbalanced fertilizer that can degrade soil fertility and reduce crop productivity. Furthermore, maize production is threatened by several biotic factors such as stem borers, and parasitic weeds especially that belong to Striga spp which cause a significant yield reduction in commercial maize farms worldwide.

Cím:	Review: Arbuscular Mycorrhizal Fungi and Phosphorus Solubilizing Bacteria: Plausible Candidates or Striga hermonthica Management in Sorghum / Magdoline Mustafa Ahmed, Rania Alrasheed Abakeer, Mohammed Mahgoub Hassan, Elshafia Ali Hamid Mohammed, Ratonyi Tamas, Abdel Gabar Eltayeb Babiker
Dátum:	2024
Megjegyzések:	Striga spp. root hemi parasitic weeds on major staple food crops including sorghum maize, pearl millet and rice, have been reported to threaten food security in sub-Saharan Africa. Among Striga spp., S. hermonthica is the most important and most prevalent in the region and thrives best under low soil fertility. Striga germinates in response to stimulants exuded by host roots. Following germination the parasite attaches, penetrates the host roots, establishes connection with the host xylem, grows parasitically and remains subterranean for 6?8 weeks. During the subterranean phase the parasite inflicts most of its damage. Several control tactics including cultural, chemical and biological methods have been released for combating the parasite. However, adoption rate of available control technologies remains minimal. Low adoption rate of the released technologies is attributable, mainly, to the mismatch of the technologies and the prevalent low-input subsistent farming system. The need for simple, inexpensively environmentally benign methods of control that affect the parasite at early stages of development is imperative. In nature, the Striga germination stimulants, collectively named strigolactones, are the hyphal branching factors of arbuscular mycorrhiza fungi (AMF) and their production and release from host roots are promoted by low soil fertility. The link between low soil fertility, Striga infection and mycorrhization promoted research on AMF as Striga antagonists with positive effects. However, AMF colonization was influenced by a multitude of variables including plant species, genotypes, drought, cultural practices, pesticides, initial soil fertility and the rhizospheric microbes, particularly phosphorus-solublizing bacteria and growth-promoting Rhizobacteria, where both synergistic and antagonistic interactions were reported.
