| 1 | Evaluation of some morphological and yield component traits relationship to soybean seed yield. |
A preliminary study was conducted in 2004 at the University of Ilorin, Teaching and Research Farm (Lat.8o29’N, long. 4o35E) in the Guinea Savannah agro-ecological zone of Nigeria. The study was to identify the best soybean/ varieties for the zone from among 13 varieties of 3 maturity classes (early, medium, and late). The design used was a randomized complete block having 13 soybean varieties as treatments and replicated four times. The preliminary study showed that TGX 1740-2F (early), TGX 1805-31 F (medium) and TGX 1448-2E (late) had highest grain and fodder yields of 1.03, 1.05 and 1.06 t/ha-1 respectively. One variety with the highest yield tha-1 from each maturity group was selected and evaluated at three population densities (333,333; 500,000 and 666,666 plant ha-1) and four levels of phosphorus (0, 30, 60,90 kg P2O5 ha-1 ) in 2005 and 2006 cropping seasons. The experiment was laid out in a Randomized Complete Block Design arranged in 3 x3 x 4 factorial, and replicated four times. Application of phosphorus fertilizer increased phosphorus fertilizer utilization efficiency with consequent increase in grin and fodder yields ha- . The late maturing varieties (TGX 1448-2E) produced optimum grain yield of 1.75 ha-1 and fodder yield of 3.46 ha-1 at 500,000 plants ha-1 and at phosphorous application rate of 60 kg P2O5 ha-1 . The medium and early maturing varieties (TGX 1805- 31 F and TGX 740 -2F) recorded optimum grain yield of 1.67 and 1.59 t ha-1 with fodder dry yield of 3.16 and 2.7 tha-1 respectively at 666, 6666 plants ha-1 and at phosphorous application level of 60 kg P205 ha-1 . From the study, optimum phosphorous levels for all the classes of soybean varieties was 60 kg P205ha-1, while the optimum plant population was 500,000 plants ha-1 for late maturing variety and 666,666 plants ha-1 for early and medium maturing varieties. | Atanda, S.
