GROWTH AND YIELD PERFORMANCES OF EARLY RIPENING SUGARCANE CLONES ON INCEPTISOL SOIL

Abstract

High soil humidity in early ripening sugarcane causes low sugar yield. Early ripening sugarcane varieties such as PS 881 could not solve this problem. Some new early ripening sugarcane varieties have been known to generate more sugar yield PS 881. This study was done to analyze the performance of early ripening sugarcane clones on Inceptisol soil in Karangploso Research Station, Malang, starting from May 2015 until August 2016. The study was arranged in a Randomized Block Design with four replications. The treatment involved five early ripening clones (PS 04 125, PS 05 124, PS 04 303, PS 06 204, and PS 06 395) and one control variety (PS 881). The results showed that PS 04 125 clone obtained sugar yield (8.51 t ha-1) greater than PS 881 variety (7.62 t ha-1). PS 05 124, PS 06 204, PS 06 204, and PS 06 395 clones obtained sugar yield (7.71-7.88 t ha-1) which was not significantly different from PS 881 variety. PS 04 303 clone obtained sugar yield (6.48 t ha-1) lesser than PS 881 variety.
