Studies on Agronomic Traits and Cane Yield of Sugarcane Promising Clones under Irrigated and Rain-fed Conditions

Abstract

The farmer has demanded high yield sugarcane variety under rain-fed condition or limited in irrigation; therefore, the aim of this study was to study on agronomic traits and cane yield of sugarcane promising clones under irrigated and rain-fed conditions for sugarcane varieties selection in rain-fed area. This experiment was carried out with split - plot in RCBD in 3 replications, the main plot was different irrigation management; (1) furrow irrigation (irrigated) or (2) non-irrigation (rain-fed) and 15 varieties/clones were used as sub-plot. The results showed that at 12 months after plantation, plant height of 15 varieties/clones under rain-fed (251.68 cm) were lower than irrigation (340.27 cm) with highly significant. While various sugarcane varieties/clones were highly significant in SPAD Chlorophyll Meter Reading (SCMR), plant height, stalk per stool, yield, Commercial Cane Sugar (C.C.S.), or ton C.C.S.. Moreover, KK09-0857 and KK09-0844 could be selected for cultivating in irrigation area and rain-fed area as 2.72 and 1.42 ton C.C.S./rai, respectively.
