Uji daya hasil 8 galur harapan kedelai hasil persilangan kultivar Slamet dan Nokonsawon
Abstract
This research had an objective to test eight hybrid soybean li nes from crossing between Slamet and Nokonsawon cultivar and the effect of Bio P 2000 Z fertilizer to the productivity of these lines. The experiment was done by randomize block design consisting of two blocks and two factors of treatment i.e. lines/cultivars and fertilizing level by Bio P 2000 Z. The lines/cultivar tested were eight lines (KH 3, KH 4, KH 6, KH 8, KH 9, KH 10, KH 11, and KH 28), and three cultivars (Slamet, Panderman and Tanggamus) as a standard. Two levels of fertilization were applied i.e. with and without Bio P 2000 Z fertilizer. The size of each experiment plot is 5m x 3m. The result of experiment showed that in general, all eight lines had higher productivity than Slamet. The productivity of KH 11, KH 10 and KH 9 was consistently higher than Slamet, Panderman, and Tanggamus. Bio P 2000Z fertilizer only had an effect to the seed productivity in the fertile soil i.e. block 2. All lines had big seed and their seeds bigger than that of Slamet and Tanggamus. Comparing with Panderman, KH 10 had bigger seeds meanwhile KH 6 was relatively smaller. Other lines had a same size of seeds with Panderman.
