Determination of the Water Requirement and Kc Values of Sugarcane at Different Crop Growth Stages by Lysimetric Method

Issue Date

Abstract

The water requirement of sugarcane was studied in a lysimeter set up at the Sugarcane Research and Seed Farm, Pyinmana, Mandalay Division, Myanmar. Sugarcane variety Phil 74/64 and grass (locally called Wun be sa; Echinochloa colona L.) were used. Daily crop water uptakes for both cane and grass were recorded from the lysimeter and the crop coefficient (Kc value) was re-derived. Sugarcane crop evapotranspiration or crop water uptake was also determined using the Penman-Monteith (FAO) method from daily weather data gathered from the nearby agrometerological station. The total sugarcane water consumption in the lysimeter study was 1369.84 mm year-1 and the average sugarcane yield was 173.29 t ha-1. Water use efficiency in the lysimeter study was 12.65 t cane ML-1 (0.13 t mm-1). The locally determined Kc values were 0.53, 0.81, 1.25, and 1.27 for initial, development, mid and late sugarcane growth stages, respectively. © 2014 Society for Sugar Research & Promotion.
