Soybean Inoculant Types and Rates Evaluated under Dry and Irrigated Field Conditions

Inoculant of Arbuscular Mycorrhizal Fungi (Rhizophagus clarus) Increase Yield of Soybean and Cotton under Field Conditions

Nutrient availability is an important factor in crop production, and regular addition of chemical fertilizers is the most common practice to improve yield in agrosystems for intensive crop production. The use of some groups of microorganisms that have specific activity providing nutrients to plants is a good alternative, and arbuscular mycorrhizal fungi (AMF) enhance plant nutrition by providin...

Soybean natural cross-pollination rates under field conditions.

Recent concerns regarding within-crop transgene flow stimulated this research to update natural cross-pollination rates in conventional sowings of modern soybean [Glycine max (L.) Merr.] in the Mississippi Delta. Two experiments were conducted in 2001 and 2002 using two soybean cultivars, "Pace" (white-flowered) and "DP3588" (purple-flowered), selected for their equivalent flowering dates. The ...

evaluation of some soybean lines to soybean cyst nematode (heterodera glycines) under control conditions and field

the soybean cyst nematode (heterodera glycine ichinohe, scn) is one of the most serious yields limiting pathogen on soybean (glycine max (l.) merr) which is found in many soybean–growing regions throughout the world. applying of resistant sources is one of the efficient measures to manage this nematode. in this study, reaction of 63 soybean lines to the soybean cyst nematode were evaluated in f...

Grain Filling Rate and Duration in Bread Wheat Under Irrigated and Drought Stressed Conditions

Abstract Eleven wheat cultivars were evaluated at 10-day intervals, beginning from anthesis, under irrigated and drought stress conditions during 2006-2007. The effects of irrigation, genotype and date of harvest were significant for most of the studied characters. Water deficit decreased pre-and post-anthesis assimilation rate, grain weight per spike, grain number per spike and 1000 grain wei...
