Abstract:: ... In nonagricultural systems, the relationship between intrinsic water‐use efficiency (WUEᵢ) and leaf nitrogen (Nₐᵣₑₐ) is known to be stronger for legumes than for nonlegumes. We tested whether these relationships are retained for major agricultural legumes and nonlegumes. We compared the response to N nutrition of WUEᵢ (and its component parts, photosynthesis (Aₛₐₜ) and stomatal conductance (gₛ)) f ...

Abstract:: ... Imazapyr and imazamox are frequently applied postemergence to control grass and broadleaf weeds in imidazolinone-resistant sunflower in Argentina. Herbicide carryover to rotational crops represents a disadvantage of these herbicides, particularly in regions with low rainfall during the months prior to rotational crop sowing. Between 2009 and 2012, field and greenhouse studies were conducted on fou ...

Abstract:: ... Intensive cereal monoculture is currently the main cause of biodiversity decline in Europe. However, it is difficult to disentangle the effects of intensive monoculture (e.g. pesticide use, mechanical ploughing and reduced protective cover), let alone evaluate how far the reduction of crop diversity affects biodiversity. It remains unclear to which extent the consequent decrease in food resources ...

Solution culture was used to test the response of sunflower (Helianthus annus L.) and wheat (Tr ...

Abstract:: ... In India wheat is conventionally planted on flat-bed and irrigation is applied by flooding, which results in low water-use efficiency. Efficient use of irrigation water is a major researchable issue in most command areas for improving crop productivity. Resource conservation technologies aimed at improving productivity and water-use efficiency such as raised-bed planting have been found useful in ...
