Field experiments were conducted in Stoneville, MS, to determine the impact of soybean planting date and maturity group on stink bug (Heteroptera: Pentatomidae) populations. Maturity group IV and V soybeans were planted on three planting dates in 2003 and 2004. Planting dateswere lateMarchÐearlyApril, lateAprilÐearlyMay, and lateMayÐearly June. Plotswere sampled weekly with a standard 38.1-cm-d...

in order to determine of the proper sowing date of steckling (rootlet) and harvesting date of seed, an experiment was conducted in ardabil agricultural research station (alarough) in 2004- 05 growing season in split-plot in randomized complete block design arrangement with four replications. four different planting dates viz. 5th march, 20th march, 4th april and 19th april– were allocated to th...

determination of the response of differentcrop varieties to environmental variables from planting to harvest is one of the fundamental pillars of agriculture planning to achieve maximum yield and desirable quality. changing planting date by effect on vegetative and reproductive growth period and balance between them, will affect yield and product quality. in order to study the responses of four...

to determine the best planting date and irrigation schedule in a cotton field (gossypium hirsutum var.varamin) in garmsar region an experiment was conducted in 2011. the experimental design was splitplot based on randomized complete block with three replications. three irrigation termination dates (2011sep 11th, 2011 sep 21st and 2011 oct 2nd) arranged in main plots as main factor and three pla...

To circumvent drought conditions persisting during seed fill in the mid-south U.S. soybean production region, researchers have developed the early soybean (Glycine max [L.] Merr.) production system (ESPS), which entails early planting of short-season varieties. Because soybean supplies a preponderance of the world's protein and oil and consumption of soy-based foods has been associated with mul...
