A field experiment was conducted to evaluate the effect of planting pattern and irrigation system on antioxidant activity of wheat and Persian clover. The experiment was carried out as a two-factor factorial with three replications. The first factor was irrigation system (conventional and partial root-zone irrigation) and the second was planting pattern (sole wheat, sole Persian clover, alterna...

In the next decades, forage legumes are likely to become more important. However, predicted climate change may increase the risk of droughts and thus influence their agricultural performance. Decreases in yield due to water shortage are well documented, while influences on nutritive values are inconsistent. Therefore, we examined the effects of drought on crude protein (CP), neutral deterge...

One of the most significant yield losses in tomato ( Solanum lycopersicum L.) is due to weeds. Yellow and purple nutsedge, large crabgrass, Palmer amaranth are troublesome weed species production throughout southeastern United States. This study aimed determine impact soil steaming, plastic mulching, cover crops on suppression, height, fruit yield. The used were hairy vetch Vicia villosa ), cri...

Extensive proteolysis during fermentation of highprotein legumes reduces dietary N-use efficiency in ruminants. Research has demonstrated that enhancing the level of fermentable carbohydrates in crops entering the silo may reduce protein degradation by increasing the rate of decline in pH. The objective was to evaluate whether delaying cutting time during the day, to allow accumulation of total...

BACKGROUND AND AIMS Increasing soil salinity poses a major plant stress in agro-ecosystems worldwide. Surprisingly little is known about the quantitative effect of elevated salinity on secondary metabolism in many agricultural crops. Such salt-mediated changes in defence-associated compounds may significantly alter the quality of food and forage plants as well as their resistance against pests....

This study focused on confirming the grazing selectivity of sheep, more and less selective, in pasture New Zealand, under two different phenological stages forage. Two experiments were conducted: 1) Comparison selective non-selective sheep irrigated with perennial ryegrass white clover. 2) A comparison was performed a high rate senescence composed ryegrass, barley barnyard grass. The botanical ...

in order to investigate of different salinity stress and plant densities effects on quantitative and qualitative forage and grain yields of kochia a randomized complete block design in factorial arrangement with three replications was used. a field study was conducted in 2011 cropping season in agriculture experiment satiation, college of agriculture, islamic azad university, arak branch treatm...

Techniques based on terminated cover crops are proposed in organic agriculture instead of traditional inter-row tillage for weed control subsequent grain crops. We estimated the profitability and evaluated riskiness novel techniques compared to one. Two-year yield data from three on-farm trials corn one soybean northern Italy were combined with cost revenue calculate compare gross margin distri...
