Effect of two mixed cultivars sugarcane growing on yield and yield component traits

Abstract

The objective of this experiment was to investigate the response of two mixed sugarcane cultivars to its yield and yield components traits grown under the sugarcane planting system across the dry season under rainfed condition. The sugar canes were tested by planting 10 pairs mixed cultivar compared with 5 single cultivars of sugarcane cultivation, a total of 15 treatments. The two mixed cultivars combination consists of KK3, Kps01-12, KKU99-02, MP02-458, and UT-13. The experiment was carried out at Agronomy Research Station, Faculty of Agriculture, Khon Kaen University during January 2015 to January 2016.The experimental design was RCBD with 3 replications. At 12 months after planting, the data were recorded including cane yield, sugar yield, C.C.S., brix value, and yield components (millable cane, stalk diameter, and stalk length). The results showed that all traits measurements are statistically different except stalk diameter. The mixed cultivar between UT-13 and KKU99-02 provide high yield and sugar yields when mixed cultivar planting. While KK3 yields have high yields in a single planting system, it cannot be grown well with other varieties. It also found that  high yield cultivars will have a millable cane and stalk length high as well.
