Abstract

• This study was conducted to investigate yield and yield components of five different maize varieties such as V1: Waxy corn (Sticky Big) indicated as Zea mays L.var. ceratina Kulesh., V2: Sweet corn (Angel 131) as Zea mays L. var. saccharata (Sturter) L. H. Bailey., V3: Flint corn (Padamyar) as Zea mays. L. var. indurata (Sturter) L.H. Bailey., V4: Peruvian maize (Nga Cheik) as Zea mays. L. var. microspermae (Sturter)L.H. Bailey., and V5: Flour corn (Meilan) as Zea mays. L. var. amylacea (Sturter) L.H. Bailey.was carried out at Vegetables, Fruits Research and Development Center (VFRDC), Yemon, Hlegu Township, Yangon Region from September to January, 2018. The experiment was laid out in randomized complete block design with four replications. The data recorded on various parameters were analyzed using computer software Statistics 8.0. The results showed that the plant height of Angel 131 (Sweet corn) (V2) (215.15cm) which was the tallest and the shortest (143.70) by Nga Cheik (V4) at 56 DAS (day after sowing). The maximum number of leaf (12.8) was found in Angel 131 (V2) and the minimum number of leaf (8.94) in Nga Cheik (V4). The maximum kernel weight (326.60 g) and the maximum grains yield (103.38 g) in Angel 131 (V2) and the minimum kernel weight (137.60 g) and the minimum grains yield (39.51g) in Nga Cheik (V4) were also recorded. It is concluded that among five varieties, Angel 131 (V2), Sticky Big (V1) and Meilan (V5) varieties were observed the highest value of yield and yield production.
