| Abstract/Contents: | "The purpose of this study was to obtain information on rates and salinity levels of irrigation for growth of Kentucky bluegrass by minimizing the hazard of salt accumulation in the sand based growing medium. Root zone profile consists of 20 cm sand based top soil, 20 cm of coarse sand as layer to interrupt capillary rise and 10 cm of reclaimed paddy soil as a base of the root zone profile. Topsoil was a mixture of dredged sand and peat with a ratio of 95%: 5% by volume. The columns were soaked into 5 cm depth saline water reservoir with salinity level of 3-5 dSm-1. Salinity levels of irrigation water were 0, 2 and 3 dSm-2. Irrigation rates were 3.8, 5.7 and 7.6 mm day-1 which were equivalent to 70%, 100% and 130% of average ET (evapotranspiration) rate of Kentucky bluegrass, and irrigation interval was 3 days. Salt accumulation was due to irrigated water and moved up water from shallow water base. At the end of second year, the accumulation of salt in the rootzone showed ECc of 3.86, 4.7 and 5.1 dSm-1, and SAR of 19.2, 23.9 and 27.5 when the salinities were 0, 2 and 3 dS m-1, respectively. Irrigation rates of 100% and 130% of ET rate with saline water did not decrease ECe and SAR in growing media. The growth of KBG was influenced by irrigation rate in the 1st year, however, salinity level was more critical in the 2nd year. Compared to non-saline water, saline water of 2 and 3 dS m-1 resulted in decreased visual quality by 3.2% and 16.5%, by 6.4% and 39.3% in clipping weight, and by 5.5% and 5.0% in root mass, respectively." |
