Plant breeders of field crops have traditionally used multi-environment trials to select among advanced breeding lines for adaptation either to unpredictable target environments or to a range of partially controlled, mainly irrigated, environments. This approach is expensive, difficult to interpret and has resulted in only modest gains in drought prone by: 1. Biomass production, soil water extraction, and water-use efficiency (WUE, kg dry matter (DM)/ growing-season water use) of tropical, summer-growing and temperate, winter-growing forage legumes suited to short-term rotations with crops were compared over several growing seasons in southern Queensland. Tropical legumes lablab (Lablab purpureus cvv. Highworth and Endurance), burgundy Cited by:
This book presents the most comprehensive and up to date review of research on different cool season grain legume crops, nutrients management, biotic and abiotic stresses management, agronomical approaches for drought management, salinity, drought, weed management and water use efficiency, impact on international trade around the world. The grain legumes are grown mainly as pulses providing food for humans, while pasture legumes are cultivated to feed domestic animals. Based on plant utility and economy, legumes are categorized into major and minor species. Major legumes are popular and common with well-established domestication and cultivation, agronomic practices Author: Jacob Popoola, Omena Ojuederie, Conrad Omonhinmin, Adegoke Adegbite.

efficiency (WUE). It is highly appropriate that we meet to discuss this topic, particularly metho dologies for selection of grain legume genotypes with high water use efficiency.
Or McOonald has. Water use efficiencies for dry matter production (WUE dm) of up to 30 kg ha −1 mm −1 for V. faba and V. narbonensis at Merredin, and water use efficiencies for grain yield (WUE gr) of up to 16 kg ha −1 mm −1 for P.
sativum and 13 kg ha −1 mm −1 for V. faba at Mullewa, were comparable to those reported for cereals and other grain legumes in previous studies in this and other by: Plant breeding over the last century has indirectly increased water use efficiency of the major grain crops because yield has increased with no additional water use.
These increases have been substantial in all major food by: Legume crops used 10 to 25% more seasonal water than wheat (Triticum aestivum L.) across environments, but WUE (kg dry matter ha −1 mm −1 of water) of legumes was 0 to 25% greater than that of wheat.
Green-manure and forage legumes generally had greater water use and WUE than grain legumes, and this was associated with their longer growing season and higher dry matter.
To make informed decisions on whether to include legumes in cropping systems, information is needed on water use by legumes and its effect on soil water availability to subsequent crops.
The objectives of this study were to determine the water use, water use efficiency (WUE), and soil water depletion pattern of four grain legumes and three.

We completed a global meta-analysis of published literature that contains both a measure of leaf nitrogen content and a measure of leaf water use efficiency for agricultural legumes: Cajanus cajan (pigeon pea), Cicer arietinum (chick pea), Glycine max (soybean), Lens culinaris (lentil), Lupinus by: 7.

Eur J Agron 15(4), – CrossRef Google ScholarCited by: The intrinsic water use efficiency (WUE) of crop legumes is generally greater than that of non-legume crops, but we make poor use of this knowledge in agriculture.
Breeding programs for legumes, with well-defined goals and trait metrics, could greatly enhance the WUE of current global by: 7. Water use efficiency (WUE), the ratio of grain yield to crop water use, provides a simple means of assessing whether yield is limited by water supply or other factors.
Based on this assessment, yields of commercial dryland wheat (Triticum aestivum L.) crops in. improves water use efficiency. Nevertheless, grain legumes remain poor cousins to the major cereal crops (rice, wheat, maize) due to the ever-increasing global demand for cereals from increasing human populations.
Globally, the priorities for cultivation, research and development in grain legumes remain secondary to those for. Nitrogen fixation potential and residual effects of selected grain legumes in a Kenyan soil George N. Chemining’wa water use efficiency and were comparable to the local checks (common bean (variety Katumani ) and nitrogen residual effects is critical in the selection of legumes for integration into the low nitrogen maize.
Water use efficiency (WUE) is defined as the amount of carbon assimilated as biomass or grain produced per unit of water used by the crop. One of the primary questions being asked is how plants will respond to a changing climate with changes in temperature, precipitation, and carbon dioxide (CO 2) that affect their WUE At the leaf level, increasing CO 2 increases WUE until the leaf is exposed Cited by: Improving Water use Efficiency of Annual Crops in the Rainfed Farming Systems of West Asia and North Africa - Volume 23 Issue 2 - P.
J. M. Cooper, P. J. Gregory, D. Tully, H. C. HarrisCited by: Thus, it is crucial to understand traits influencing water uptake and the efficiency of using water to produce biomass. Global comparisons and comparisons at specific locations reveal that water use of different grain legumes is very similar, which indicates that water use efficiency varies over a wide range due to differences in biomass and by: 6.
