Abstract:

The effects of N (0, 0.3 and 0.5 kg), K (0 and 0.5 kg) and betaine (0 and 50 mg/litre), applied alone or in combination, in alleviating water stress in summer maize cultivars Shaandan 911 and Shaandan 9 were determined in a field experiment conducted in China during May to October 2003. Dry matter content at seedling, elongation, heading and mature stages of the crop, as well as grain yield and water use efficiency per dry matter and grain were highest with the combined application of nitrogen, potassium phosphorus and betaine in both cultivars under water deficit. Shaandan 9 and Shaandan 911 recorded higher values for the parameters measured under water deficit and adequate water supply, respectively.
