Walden-Coleman, A. E., Rajcan, I. and Earl, H. J. 2013. Dark-adapted leaf conductance, but not minimum leaf conductance, predicts water use efficiency of soybean (Glycine max L. Merr.). Can. J. Plant Sci. 93: 13–22. The conductance to water vapor of dark-adapted leaves (gdark) has been shown to be negatively correlated with whole-plant water use efficiency (WUE) in soybean, but the physiological basis of this relationship is unknown. It is also not clear how gdark compares with the minimum leaf conductance of wilted leaves (gmin), a trait that has been studied extensively across a broad range of species. We compared gdark to gmin of soybean leaves and found that gdark values were consistently much higher than gmin values measured on the same leaves. Also, across seven soybean varieties known to differ for WUE, gdark but not gmin was correlated with WUE. Thus, gdark and gmin should be considered distinct traits. We measured gdark at two different leaf positions, and found that gdark measured at the lower leaf position (two main stem nodes below the youngest fully expanded leaf) was best correlated with WUE. We then used this method to screen a selection of current commercial soybean varieties adapted to Ontario, Canada, for variation in gdark. The range in gdark among the commercial varieties was as broad as that measured previously among more diverse genotypes, suggesting that Ontario soybean varieties might also vary widely for WUE.

Initiation Stage

A field experiment was carried out in rainy seasons of 2009, 2010 and 2011 to study the effect of irrigation schedules on yield, water use efficiency and other traits in soybean. Seven irrigation schedules consisted of irrigations at seedling stage (15–20 days after sowing), flower initiation stage, seed filling stage (20 days after flower initiation) and four different combinations of these 3 stages. Irrigation at flower initiation + seed filling stages produced the highest seed yield (3221 kg/ha). Maximum average values for seed index (14.59 g) and harvest index (50.87%) were recorded in this treatment. This treatment also recorded maximum net returns (₹ 44028/ha) followed by irrigation at seedling + flower initiation + seed initiation stages (₹ 42046/ha) and flower initiation stage (₹ 41880/ha). Control (no irrigation) had maximum water use efficiency (84.85 kg/ha/cm) followed by irrigation at flower initiation stage (83.30 kg/ha/cm). Studies indicated that irrigation to the soybean crop at flower initiation and seed filling stages helps to obtain the optimum yield and earn maximum net returns.
