摘要

Response of jasmine rice, KDML 105 cultivar, to different soil amendments; gypsum (0.08 t ha-1), ground limestone (0.03 t ha-1), rice husk (0.16 t ha-1), rice husk biochar (0.08 t ha-1), acacia leaf (0.16 t rai-1), was experimented in saline sodic and sodic soils. Soil amendments applied slightly increased yield and quality of jasmine rice; acacia leaf and gypsum gave, with no statistical difference, the highest grain yield of 1.01 and 1.18 t rai-1 when grown on saline sodic and sodic soils, respectively. Rice husk stimulated the highest aromatic 2-AP contents of 3.50 and 3.97 mg kg-1 when rice grown on respective sodic and saline sodic soils. This coincided with the highest S concentration in grain, the lowest soil moisture content at the depth between 10-20 cm, the poorest quality of cooked rice, especially in the case of its taste. Aromatic 2-AP in grain statistically correlated with N concentration in grain (r = 0.85**), whereas Na, Zn, Mn and Cu concentrations had significantly negative correlation with rice yield. Soil amendments, gypsum in particular, improved top soil properties and reduced salinity and sodium adsorption ratio of logging water throughout growth stages when compared to no soil amendment.. In the case of saline sodic soil, gypsum, however, induced the highest ECe, causing rice to produce significantly lowest percentage of filled grain. Rice husk decreased salinity level the most. Incorporated acacia leaf released the highest nitrogen which was consistent with height and grain yield of rice grown on the saline sodic soil.
