“…The differences in efficiency are attributed to differences in environmental factors between the two seasons, particularly in the amount of radiation intercepted which according to Lomas et al (1974) and Tan ner and Sinclar (1983) adversely affects dry matter production, hence water use efficiency.…”

Maize (Zea mays) was grown in four consecutive (wet and dry) seasons in two years at the experimental fields of the International Institute of Tropical Agriculture, Ibadan, Nigeria. Water use of maize and yield responses in the humid forest-Savanna transition zone of Nigeria were assessed using drainage lysimeters which were irrigated daily depending on the evaporative demand of the atmosphere. Results show significant differences (p < 0.01) in water use, yields and yield components between the seasons and the years. Seasonal averages of water used from sowing to harvest were 363 mm and 271 mm for the wet and dry seasons, respectively. These are equivalent to mean water use efficiency (WUE) of 122 g and 176 g of water per gram dry matter for the wet and dry seasons, respectively. Significant yield differences were rePlease note that this electronic prepublication galley may contain typographical errors and may be missing artwork, such as charts, photographs, etc. Pagination in this version will differ from the published version. corded between the wet (7.6 t ha Ϫ1 ) and dry (3.8 t ha Ϫ1 ) seasons and between the first (6.6 t ha Ϫ1 ) and second (4.8 t ha Ϫ1 ) years, respectively. Also, the lysimeter surfaces gave superior maize yields when compared to the rain-fed plots. Two years average lysimeter yields were 9.1 t ha Ϫ1 and 4.3 t ha Ϫ1 for the wet and dry seasons, respectively, compared to rain-fed plots yields of 5.6 and 3.3 tonnes ha Ϫ1 during the same period. The result shows a significant yield response irrespective of the season, to increased water input from higher rainfall amount, distribution or supplementary irrigation.

The influence of the growth rate on the water use efficiency by different cultivated plants in consideration of C3‐ and C4‐species The influence of the growth rate (dry matter production per unit of time) on the water use efficiency by different cultivated plants (maize, sunflower, durum wheat, sorghum, amaranthus) was examined using hydroponic culture. The water use efficiency was expressed by the relative water requirement (1 transpirated water per kg produced dry matter), at which the evaporation was absolutely eliminated. The results showed a definite conformity with the hypothesis, which was taken as the basis for these studies: – The relative water requirement was not constant on the basis of the changing growth rate during the course of growth and development of the plants. With increasing growth rate decreased the relative water requirement. The effect of the increasing growth rate on the decrease of the relative water requirement was greater all the more, the more the growth rate increased. – Plants of one and the same species and variety but with different growth rates had different relative water requirements. Those ones with a higher growth rate showed a lower relative water requirement. An influence of the growth rate on the different relative water requirement of C3‐ and C4‐species also was observed. Under better growth conditions for C3‐plants than for C4‐plants, the growth rate of C4‐plants was slowed down, so the relative water requirement was higher than by C3‐species. Concluding from this research, there is the possibility to employ the growth rate of plants for a measure to use water more efficient in plant cultivation.
