This examination plans to investigate the productivity of several flowering phase sorghum varieties as measured by fresh weight and dry matter weight. This research used a Completely Randomized Design (CRD) with 4 different varieties and 5 replications. The sorghum varieties analyzed were Super 1, Super 6, Super 2 and Numbu. The factors estimated were the fresh weight of leaves, stems and panicles and the dry matter weight of leaves, stems and panicles. The results of the analysis showed that the varieties gave very significant differences (P<0.01) in the fresh weight and dry weight of leaves, stems and panicles. The Super 6 variety had leaf fresh weight, panicle fresh weight, leaf dry weight and panicle dry weight which were very significantly (P<0.01) higher than the Super 1 and Numbu varieties. The Super 1 variety had a fresh stem weight that was very significantly (P<0.01) higher than the Super 2 variety and the Numbu variety, but was not significantly different (P>0.05) from the Super 6 variety. The Super 2 variety had a leaf dry weight. and stem dry weight was significantly (P<0.01) higher than Super 1 and Numbu varieties. It was reasoned that the various assortments of sorghum plants analyzed gave differences in productivity, where the Super 6 variety had the highest productivity.
