Title:
Effects of phosphorus on seed oil and protein contents and phosphorus use efficiency in some soybean varieties
Publication date:
2010
Summary:
Phosphorus (P) uptake and utilization by soybean (Glycine max (L.) Merrill) is essential for plant growth. Therefore, this experiment was conducted to evaluate the P effects on selected soybean varieties based on the seed oil content (SaC) and the seed protein content (SPC) and to assess the physiological responses associated with changes in shoot P-utilization efficiency (SPUE). The experiment was carried out during 2008 and 2009 with a split-plot design at the Agronomy Department, Kasetsart University, Bangkok, Thailand. The main plots were for tested three P levels in a nutrient solution (0.5, 1.0 and 2.0 mM F), with subplots for the three soybean cultivars, CKBl, SJ5 and CM60. The results indicated that at maturity, the P levels of 2.0 mM P decreased SPUE by 27 % compared to that of 0.5 mM P (the control). sac was not significantly affected by the P level. Relative to the control, the P nutrition levels of 1.0 and 2.0 mM P significantly decreased SPC by 4% and 5%, respectively. There were no significant differences in sac between varieties. The SPC of CKE 1 was 8% greater than that of SJ5 but showed no significant difference to that of CM60.
