abstract a hydroponics experiment was conducted to compare effect of fe-deficiency on concentration, uptake, translocation of fe, zn, mn in some plants. a completely randomized block design in triplicates was conducted in research greenhouse. seven plants with different fe-efficiency contained two bread wheat genotypes (triticum aestivium l. cvs. backcross roshan and qods), triticale (x. tritic...

Cassava production in the state of Alagoas is mostly carried out by small rural producers who adopt little management technology, and routinely do not replace nutrients due to high cost chemical inputs. In this agricultural model, knowledge use strategies that include natural biological processes soil, mainly microbiota present environment, such as arbuscular mycorrhizal fungi (AMF), can be pre...

Abstract A field experiment was applied during the agricultural season 2021-2022 in one of farms located Al-Muthanna Governorate. In order to study effect scheduling irrigation water and adding organic matter bio-bacterial fertilizer on concentration some nutrients wheat plant ( Triticum aestivum L.), carried out by distributing split plates using a randomized complete block design R.C.B.D.

Drought is one of the most important factors worldwide, which limits crop production, especially in semi-arid areas. The use beneficial microorganisms such as arbuscular mycorrhizal fungi (AMF) may represent an eco-friendly and biological technique to increase crops yields ensure food security. purpose this paper was evaluate effect AMF inoculation on a promised variety hulless barley (Hordeum ...

Coffee production has decreased due to environmental and management factors. The current plantations are old unproductive, also the rust problem, caused by fungus Hemileia vastatrix Berk & Br. Furthermore, shade in systems with consequent increase soil erosion, addition agrochemicals. Currently, planting of new varieties resistance is increasing. it been shown that various biofertilized perenni...
