Title

RELATIONSHIP OF CLIMATICAL AND SOIL PROPERTIES AND WATER REQUIREMENT OF SC704 FORIAGE CORN IN LASHGARAK FOR DESIGNING OF RAINWATER HARVESTING SYSTEMS IN ARID AND SEMIARID ZONES

Abstract

 With attention to rate of growth of population in Iran, it is necessary to produce more food. Also for limitation of water resource of country, one method of developing of irrigated fanning is: "Rain Water and Harvesting Systems" in ARID AND SEMIARID ZONES. In this research, some of climatical and soil properties and water requirement of recommended Crop (SC704 FORAGE CORN) was investigated. For this aim 24 plots prepared at LASHGARAK LATIAN watershed in north of Tehran. Data was measured in watering year Qct 2001- Sep 2002 are: daily rain, runoff, evaporation from class A pan. The plots were 30 to 100 m2, This research was conducted with 3 treatments of rate of catchments to basin areas, as 1:1, 2:1 and 3:l.Respectively. The results of forage maize (SC704 variety) Yield showed that this system can supply 50 to 70 present of needed water for an economical crop. Also, supplementary irrigation water was 10 to 20 percent of actual evapotranspiration of forage maize. Yield efficiency of FORAGE CORN in the treatment with 3:1 runoff to basin area was 70% of control Yield, equal 28.8 tons/ha. The yield of other treatments (2:1 and 1:1) Were 22.8 and 9.6 tons/ ha. The important point in this system is reserving a part of rainwater harvested in separate place for supplementary irrigation of crop in summer, that in this research was 62 mm or 62 lit/ m2.Althogh amount of runoff collected was 55 to 105 lit/m2 in different plots.
