Abstract:

Single grain sowing mode is becoming the most important trend in maize breeding and production in China. This study aimed at different age and different genotype of maize varieties, the effects of maize seed dressing on seed emergence rate were analyzed under field conditions by using the maize seed coating agent sold on the agricultural capital market. The results showed that all treatments indicated significant increase in emergence rate compared with the control. The seed coatings composed of Manshijin, Ruisheng, Gaoqiao, and Dingmiaoxin had relatively good effects in improving seed emergence rates which should be considered of appropriate priority use in the production of single grain sowing.

Key words: Maize, Single-seed sowing, Seed coating, Emergence rate
