| Abstract | Saline soil is one of the major threats to plant production since physical andchemical properties of such a soil are unsuitable for plant growth. Hence,technologies have been developed to improve soil fertility under salineconditions. Rice husk charcoal has received much attention as a means toimprove soil fertility and increase crop yield. The present study investigatedthe effects of rice husk charcoal and cow manure on increasing the growthand yield efficiency of two rice varieties under saline soil conditions. Theexperiments were conducted in a greenhouse using a completely randomizedexperimental design with 4 replications. Rice husk charcoal or cow manurewas added at rice transplanting phase in comparison with the sole use ofsaline soil as follows: 1) saline soil alone, 2) rice husk charcoal at 600 kg/rai,3) rice husk charcoal at 900 kg/rai, 4) cow manure fertilizer at 600 kg/rai and5) cow manure fertilizer at 900 kg/rai. KDML 105 and line UBN02124-RGDUMAS-192-2-5-5 salinity tolerance rice varieties were used. The results showedthat the salinity tolerance variety exhibited higher survival rate than KDML 105.All organic material amendments resulted in higher survival rates than withno amendment. However, rice yield was more strongly affected by the soilsalinity in the case of KDML-105 than in the case of the salinity tolerancevariety. The applications of rice husk charcoal, both at 600 and 900 kg/rai,resulted in the highest KDML 105 rice grain yield (2.18 and 2.28 g/stem,respectively). In the case of salinity tolerance variety, rice husk charcoal at900 kg/rai amendment resulted in a higher yield of quality rice than cowmanure fertilizer at 900 kg/rai, which although resulted in a higher grain yield,led to a lower percentage of full seeds. These results illustrated that rice huskcharcoal amendment could effectively increase plant nutrient use. Usingorganic materials to improve saline soil for rice production under salineconditions should be implemented by adding adequate nutrient materials incombination with rice husk charcoal to increase adsorption and improvechemical properties of saline soil. |
