effects of foliar urea spray at different plant development stages on grain yield and protein percentage of tow dryland wheat varieties

چکیده
to study the effects of urea foliar spray at different plant growth stages on grain yield and protein percentage of two dryland wheat varieties of sardari and azar 2, an experiment was conducted in east mangor agricultural station of mahabad in 2007– 2008. the experiment design was split plot based on randomized complete block design with three replications. treatments were 50 gr×10 m-2 n as urea foliar spray at tillering, tillering +1.5 lit× ha-1 of 2,4-d herbicide, jointing, heading stages and control(without urea spray) for varieties of sardari and azar 2. results showed that the grain yield of azar 2 (2270.8 kg/ha) was greater than sardari (1932.5 kg/ha). urea foliar spray treatments affected the length of spike, grain yield and its components, biological yield and protein percentage. the greatest grain yield belonged to urea foliar spray at tillering +1.5 lit× ha-1 of 2,4-d herbicide treatment(2371 kg/ha) that had greater grain yield rather than control by 17%. the greatest protein percentage (16.05 %) belonged to urea spray at flag leaf stage and sardari variety treatment. its be seemed that application of n as foliar urea spray instead of urea fertilizing, will increase grain yield and protein percentage, and application of urea foliar spray accompanist with 2,4-d herbicide is the most effective time.
