Abstract

The portion of soil water that is easily absorbed by plant and usually leads to maximum yield is defined as "Readily Available Water" and is shown as p. This is an important parameter for irrigation scheduling and is useful for determining the irrigation depth (d) and frequency (i). The value of p depends upon the plant species, growth period, rate of EVAPOTRANSPIRATION (ETo), and the type of soil.In the present study the value of p is determined for grain CORN VARIETY SINGLE CROSS 704 in 2 stages of growth periods in Karaj. The first stage was from seed establishment till appearance of the sixth leaf and the second stage was after appearance of this leaf till soft grain.'This research was carried out with a split plot design in the research station of Seed and Plant Improvement Institute in Karaj for a period of 3 years. The main plots were allocated to the treatments of the first stage and the levels of p fraction in this stage were 0.30 and 0.60. The subplots for the second stage were irrigated when p values were 0.30, 0.50 and 0.70. The amount of p was kept 0.8 for the last growth stage (from soft grain till harvesting). These 6 treatments were replicated 4 times. In this study production potential parameters as grain yield, ear yield dry mater and weight of 1000 grains were determined. Also by measuring the amount of irrigation water, soil moisture balance and evapotranpiration, the water utilization and application efficiency were obtained.Analysis of the results show that by doing short irrigation intervals (p=0.30) during the first stage could be had a good crop establishment and vegetative growth period, then enable us to reduce the number of irrigation (longer irrigation intervals) (p=0.70) in later growth stages. The amount of consumptive use of water in this treatment was 7898 m3ha-1 and grain yield's was 12 ton ha-1.
