The use of computers in the planning and design of irrigation projects

, : The use of computers in the planning and design of irrigation projects. Archiv fur Acker und Pflanzenbau und Bodenkunde 20(5): 327-331

Optimum pipe systems, pipe lengths and diameters, reservoir capacities, and irrigation regimes for various crops can be calculated by linear (simplex method) and dynamic programming, based on data for soil and climatic conditions, plant water requirements, cropping structure and economic aspects.

In field trials in 1996/97 at 6 sites in Italy, 25 durum wheat cultivars were given 2 or 3 N rates, varying between 50 and 180 kg/ha. At 3 sites, there were significant differences in yield between N rates, 4 showed differences in grain protein co...
