Plot size under field conditions to determine soybean agronomic characteristics

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...

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 ...

Apparent photosynthesis of soybean plants as affected by changes in leaf water potential under field conditions

Non-destructive Image Analysis to Determine Suspended Sediment Size Distribution Characteristics under Varying Flow Conditions, Cazenovia Creek, Ny

Recent studies suggest that suspended sediment in rivers may move predominantly as floes rather than as individual (discrete) particles. Research on flocculation has been facilitated by improved analytical technologies, including image analysis. Because image analysis is a relatively new analytical approach, there is limited information on quality assurance/quality control (QAlQC) procedures. N...

Aggregate Size Distribution Indices Influenced by Different Types/Managements of Plant Residues under Field Conditions

1- INTRODUCTION Nowadays, environmental aspects of soil erosion are specifically considered by researchers. In this regard, secondary (aggregate) particle size distribution (SPSD) is so important in different issues such as nutrient loss, pollutant transport and carbon cycle. Aggregate size distribution is known as the representative of soil structure, which is by itself regarded as a dynami...
