Yield potential of exotic maize varieties in Maha Sarakham Province

Abstract

Five maize varieties were trialed to evaluate the agronomic traits of yield and yield component under field conditions at Agricultural Field Research, Department of Agricultural Technology, Faculty of Technology, Mahasarakham University, Khamriang campus, during November 2016 – March 2017. The experiment was laid out in a randomized complete block design consisting of five treatments with three replications. The results showed that there were significant differences in yield, yield component and some agronomic traits among different violet maize varieties, except ear length, ear diameter, kernel rows, number of grain per row, number of grain per ear and grain yield per rai. Khow Neaw Dum Phitsanulok (black kernel) had the highest yield and grain yield with the mean of 1,030.20 and 804.33 kilogram per rai, respectively. Among the exotic maize varieties, Strubbes Orange variety showed the highest yield and grain yield with means of 1,097.9 and 878.27 kilogram per rai, respectively. The Strubbes Orange was the most adapted variety to the Maha Sarakham Province environment and it is suggested to have further potential for a breeding program.
