As the incidence of water deficit and heat stress increases in many production regions there
is an increasing requirement for crops adapted to these stresses. Thus it is essential to …

Background Drought is a major limiting factor seriously influencing worldwide soybean
production and its impact on yield, morphological and physiological traits depend on the …

Food production and water use are closely linked processes and, as competition for water
intensifies, water must be used more efficiently in food production worldwide. A field …

Intrinsic water use efficiency (WUEintr), the ratio of photosynthesis to stomatal conductance
to water, is often used as an index for crop water use in breeding projects. However …

Efficient use of N fertilizer has become crucial due to fertilizer costs and the impact of
excessive N on the environment. Diagnostic tools for estimating plant N status have an …

Growing conditions in the US Midsouth allow for large soybean [Glycine max L.(Merr.)]
yields under irrigation, but there is limited information on planting dates (PD) and maturity …

Soybean research has found that nodule traits, especially nodule biomass, are associated
with N 2 fixation ability. Two genotypes, differing in nodule number per plant and individual …

Diversifying annual crop rotations is postulated to promote soil ecosystem services through
reduction of greenhouse gas emissions, control of soil evaporation, moderation of soil freeze …

Drought causes significant soybean [Glycine max (L.) Merr.] yield losses each year in rain-
fed production systems of many regions. Genetic improvement of soybean for drought …

Delayed wilting is observed in a few unusual soybean [Glycine max (L.) Merr.] genotypes,
but the reasons and importance of this trait for conferring agronomic drought tolerance are …
