Abstract:
Field plot experiments were conducted to investigate the effects of different application quantities of controlled-releases urea and common urea on spring maize yield and apparent N recovery rates at maize foundation seed farm, Taojia, Jilin Province. The results showed that in comparison with common urea, the controlled release urea at 100% and 75% application rates increased the spring maize yield rate by 10.8% and 8.1%, the difference was significant. Mixed application of controlled release N and common N could increase maize yield obviously by 7.3%. In comparison with common urea, the controlled release urea at 100% and 75% application rates increased the apparent N recovery rates by 50.4% and 57.3% and 75% application rates was higher than 100% application rates.
