The increase in food production requires reduction of the damage caused by plant pathogens, minimizing environmental impact management practices. Soil-borne pathogens are among most relevant that affect soybean crop yield. Soybean sudden death syndrome (SDS), several distinct species Fusarium, produces significant yield losses leading soybean-producing countries North and South America. Current...

Aphis glycines Matsumura (Hemiptera: Aphididae) can reduce the yield of aphid-susceptible soybean (Glycine max (L.) Merrill) cultivars. The Rag1 and Rag2 genes conferresistance to some biotypes of A. glycines. These genes individually can limit population growth of A. glycines and prevent yield loss. The impact of these genes when combined is not known. We compared the development of A. glycine...

Iron (Fe) and manganese (Mn) are essential nutrients for plants. Application of high levels of either Fe or Mn is often accompanied by relatively low levels of uptake for the other nutrient. The antagonistic relationship of these nutrient elements may occur either during absorption by roots or during translocation from roots to shoot. A greenhouse study was carried out to study the effect of so...

Abstract The progressive reduction of synthetic agrochemical fertilizers is one the key factors in shift from conventional agriculture to sustainable farming. Nitrogen (N) ruling element development agricultural production, but its use mineral form or excessive causes several environmental issues. Since release N nanocomposites coincides with their uptake by crops, loss reduces while enhancing ...

dietary lysine had 35, 40 and 65 percent greater rate of gain, gain: feed ratio and gain: protein ratio, respectively, than those pigs fed the corn-soybean meal diet at 0.9 percent lysine and 17.9 percent crude protein. At 1.0 percent lysine (14.3 percent protein), the corn-whey-yeast diet produced 25, 35 and 59 percent greater average daily gain, feed efficiency and protein efficiency ratio ov...

water and soil salinity in some regions of isfahan, east azerbaijan, and west azerbaijan provinces and also other parts of the iran are the main hindrance for crop planting. seeds of the tolerant crops to salinity such as cotton and sugar beet may have optimal germination and give acceptable performance if they become far from salt accumulation areas. to evaluate the effects of different planti...

Thirty-eight lactating dairy cows including 6 ruminally cannulated cows were used in a feeding study to assess effects of feed sources that differed in dietary nonfiber carbohydrate (NFC) composition and ruminal degradability of dietary protein (RDP) on production, ruminal, and plasma measures. The design was a partially balanced, incomplete Latin square with three 21-d periods and a 3 x 2 fact...
