Parkmeng Estuary is located in Siako District area, Trang Province, the estuary is an important nursery area for marine life; however, port construction and tourist activities affect the estuarine environmental quality. It is necessary to study effect of those activities on the environment and biological qualities in this area. The relationships between aquatic environment parameters (AEP) and phytoplankton density in this estuary were investigated using the canonical correspondence analysis (CCA) method. The AEP was classified for two main seasons, monsoon (July-October) and summer seasons (November-April) by the unweighted pair group method with arithmetic mean analysis with similarity scores of 98.79% and 98.18%. The inter-change period was May classified by CCA score at 99.54%. Two divisions, 11 families, 14 genera, and 17 species of phytoplankton were recorded in this study. The division Chromophyta showed the highest density (74.96%) followed by Cyanophyta (26.04%). Similar to AEP analysis, phytoplankton was classified as monsoon or summer species with CCA similarity scores of 74.28% and 55.00%, respectively. Phosphate, conductivity, silicates, pH, and temperature showed correlations to phytoplankton density with CCA variable scores of 0.84, 0.75, 0.74, 0.72, and 0.71, respectively. This study reveals that the density of Triceratium sp., Rhizosolenia sp., Odontella sp., and Cyclotella stylorum diatoms might be used as bio-indicators for the fluctuations of salinity and pH in this estuary.

The purpose of this study was to study the effect of cassava monoculture and cassava-Thai melon intercrop and land use efficiency. The experimental plan was randomized complete block design (RCBD) three treatments, with three replications: mono cassava, cassava-Thai melon intercrop and mono Thai melon. The results showed that the cassava-Thai melon intercrop had no effect on height, leaf weight and fresh root weight. In addition, it was found that in all treatments, there were nine types of weeds. The densities of weeds in monoculture were significantly higher than that of intercrops. The results of Thai melon found that intercrops had a longer stem length than that of mono Thai melon, but the number of branches per plant in intercrops was less than mono Thai melonIn the intercropping, fruit weight was not statistically different from that of monoculture. However, cassava-Thai melon intercrop had higher land equivalent ratio (LER) than monoculture. In conclusion, Thai melons can be intercrop ped in cassava without affecting cassava yield and Thai melon yield. It also helps to mulch the soil in the early stages of cassava growth and reduce the number of weeds.
