The effect of constant and fluctuating soil temperature and two soil moisture regimes on the growth, development, transpiration and nutrient uptake by maize seedlings was studied in a greenhouse investigation. The constant root temperatures were maintained at 30, 34, 35, 36, 37, and 38°C for both...

The objective of this experiment was to evaluate the effects of growing a deep-rooting perennial on the root system development of a subsequent crop with low root penetrating ability. These effects were measured on a gravelly Alfisol with a compacted subsoil horizon for three tillage methods (zer...

We prepared sand and gravelly sand media in rigid cylinders, with different proportions and sizes of gravels and sands at various water tensions. Cores of forest topsoil were used for comparison. We measured the growth of pregerminated maize seedlings 72 hours after transplanting them into these ...
