Soybean cyst nematode (Heterodera glycines, SCN) is the most destructive pathogen of soybean around the world. Crop rotation and resistant cultivars are used to mitigate the damage of SCN, but these approaches are not completely successful because of the varied SCN populations. Thus, the limitations of these practices with soybean dictate investigation of other avenues of protection of soybean ...

Packaging types as influencing seed quality in some soybean [Glycine max (L.) Merr.] varieties during storage period | Ratna Wylis Arief, Robet Asnawi, Reny D. Tambunan, Nila Wardani, Dewi Rumbaina Mustikawati, Made Jana Mejaya Agricultural Journals

Four stages of soybean pod development of four varieties of Glycine max were surveyed for esterase enzymes by starch-gel electrophoresis. Differences in esterase banding patterns occur among the four varieties investigated. Enzyme changes accompanying pod development were observed. Pod collection procedure affected the number of esterase bands visible, with collection in dry ice giving more vis...

Stale seedbeds are used by organic growers to reduce weed populations prior to crop planting. Ryemulches, derived from mechanically killed (rolled and crimped) winter rye cover crops, can serve the same purpose for spring-planted organic crops. Both methods can also be employed by conventional growers who face looming problems with herbicide resistant weeds. The objective of this research was t...

to evaluate the effects of sowing date, cultivars and herbicides on weed species control and soybean yield, a strip split plot layout in as a randomized complete block design with three replications was conducted in dasht-e-naz company sari-iran, in 2008. treatments included two planting dates (planting june 7th and 27th), soybean cultivars (bp, jk, 032, 033 and sahar) and herbicide application...

Soybean is an important and valuable crop for global food feed supply, providing high-quality nutrition. Globally, five countries—namely Brazil, the USA, Argentina, China India—have dominated soybean production many years. The intention of this paper to review reasons their dominance, starting with seeds. High-quality seeds enable stress-free, high-density even planting in field. Seed quality a...

the complexity of the genetic control of drought tolerance makes inevitable using of molecular methods with biometric approaches to its improvement in plants. present study was conducted by 121 advanced lines and varieties of soybean under two moisture levels, normal and drought stress with 21 microsatellite markers linked to drought tolerance in two regions, namely, rasht and gonbad-kavous. gr...

Background: Due to environmental contamination in recent years, contamination of food chain by heavy metals is not far-fetched. The purpose of this study is to determine heavy metals in soybeans cultivated in Iran to monitor the food chemical contaminants. Methods: To assess metal contamination, four varieties (Sahar, Katool, Williams, and M7) of soybean cultivated in Iran, were collected. Met...
