Agronomic traits performance of some promising lines of local upland rice (Oryza sativa L.) from SE Sulawesi grown under shading conditions

Abstract

Abstract Rice is primarily eaten by countries like Indonesia in Asia. The demanding rice rise every year and the Indonesian government is trying to satisfy the need for rice. The development rice tolerant to shade is one of the promising choices. The aim is to characterize the performance of upland a new rice cultivar. The study was conducted at the Experiment Farm, Department of Agronomy, University of Halu Oleo. Arrange in a split-plot design and repeated four times. The different shade levels as main plot and rice lines different as subplot. The shade level consists of four levels (N0=0%, N1=25-50%, N2=50-75% and N3 > 75%). The upland rice lines were G1=GS11-1, G2=GS11-2, G3=GS12-1, G4=GS12-2 and G5=Lipigo as a control variety. The results indicated that shade significantly increased the plant height, leaf area and unfilled grains number. However, the shade level affected productive tiller and grain weight to decrease.
