Two experiments were conducted to determine: first, the best time of excreta collection after force feeding of broilers to yield the maximal amount of excreta, and second, nitrogen-corrected true metabolizable energy contents of some poultry feedstuffs including yellow corn, soybean meal, corn gluten meal, canola meal and poultry by-product meal by a new precision-fed chick assay using 3-week-o...

In order to evaluate the effects of both cold and light stresses on chlorophyll fluorescence and feasibility of using chlorophyll florescence technique to evaluate effect of light intensity on cold tolerance in soybean, an experiment was done in a factorial arrangement based on a completely randomized design with three replicates. Two soybean cultivars consisted of 032 and BP grown under greenh...

The soybean aphid (Aphis glycines Matsumura) is a threat to soybean production in the Midwestern United States. Varieties containing the Rag1 soybean aphid resistance gene have been released with limited success in reducing aphid populations. Furthermore, virulent biotypes occur within North America and challenge the durability of single-gene resistance. Pyramiding resistance genes has the pote...

crop simulation models are mathematical representations of plant growth processes as influenced by interactions among genotype, environment and crop management. using crop simulation models can be an efficient complement to experimental research. models are being used to understand the response of crops to possible changes in crop, cultural management and environmental variables.while there are...

An 11-year field study was initiated in 1979 to monitor population development of Heterodera glycines. Fifty cysts of a race 5 population were introduced into plots in a field with no history of soybean production and that had been in sod for 20 years. Soybean cultivars either susceptible or resistant to H. glycines were grown either in monoculture or rotated with maize in a 2-year rotation. Du...

Nontarget injury from glyphosate drift is a concern among growers using non-glyphosate-resistant (non-GR) cultivars. The effects of glyphosate drift on nitrate assimilation and nitrogen fixation potential, nodule mass, and yield of non-GR soybean were assessed in a field trial at Stoneville, MS. A non-GR soybean cultivar 'Delta Pine 4748S' was treated with glyphosate at 12.5% of use rate of 0.8...

In order to investigate the effect of Hexaconazole (HEX) on quantitative and qualitative characteristics of two soybean (Glycine max L.) cultivars under water deficit stress, an experiment was conducted in the Faculty of Agriculture of Tarbiat Modares University in the year 2010-2011 as a factorial experiment in randomized complete block design arrangement. Factors examined in this study were s...
