Agronomic, Phenological, and Physiological Responses of Old and Modern Soybean Varieties to Soil Moisture Deficit

Soybean (Glycine max (L.) Merr.) yields have increased substantially in the past 50 years, but soybean productivity is still often limited by environmental stresses. Because an inverse relationship often exists between seed yield and stress resistance, a two-year study was initiated to examine the responses of two old, low-yielding ('Manchu' and 'Dunfield') and two modern, high-yielding varieties ('Williams' and 'Clark 63') to long-term soil moisture deficit.
