During the last decade, the production of off‐season maize has increased in several regions of Brazil. Growing maize during this season, with sowing from January through April, imposes several climatic risks that can impact crop yield. This is mainly caused by the high variability of...
Several spectrometer types for the detection of plant stress symptoms by measuring reflectance of crop canopies have been described in the literature. Only a few of them were field‐portable and combine both the visual (VIS) and near‐infrared (NIR) spectral ranges. In particular, NIR spectra...
Factorial field trials were carried out on an experimental farm near Kassel, Germany, in two consecutive seasons (2003 and 2004) in order to examine the impact of leguminous and cereal preceding crops (i) on soil N availability under subsequent potatoes and (ii) the effect of preceding crop and...
As a low‐cost strategy, the cultivation of certain salt‐tolerant crop species on calcareous saline‐sodic soils, i.e. phytoreclamation, has enjoyed great attention in recent years. A lysimeter study was carried out to evaluate whether a phytoreclamation approach alone, or in combination with some...
Field experiments were conducted in 2003/2004 in Québec to determine the effects of irrigation levels (none, low and high) and cultivars (AC Orford, AC Proteina and Golden) on soya bean (Glycine max (L.) Merr.) isoflavone concentrations and yields. Seed yield, yield components, and oil and crude...
Five cowpea genotypes, Gorom local (Go), KVX61‐1 (KV), Mouride (Mo), Bambey 21 (B21) and TN88‐63 (TN), differing in their susceptibility to water stress, were studied under glasshouse and field conditions, to determine their physiological, biochemical and agronomic responses to water deficit at...
