Abstract

An experiment was conducted at the laboratory in Faculty of Sustainable Agriculture, Campus UMS Sandakan which is situated at Mile 10, Jalan Sungai Batang, 9000, Sandakan, Sabah with latitude 50 55' N and longitude 1180 02'E. This experiment studies the effect of different drying methods and packaging materials as lining on TR-9 paddy seed viability stored under ambient condition. The objective of the research are to determine the effect of different packaging materials on the viability of paddy seed under ambient condition and to evaluate the effects of different drying methods on the viability of paddy seed under ambient condition. Two factors were used in this experiment which are different drying methods and different types of packaging material. The experiment design consist of 3 drying methods which are mat drying, pavement drying and mechanical drying and 3 packaging materials which are polypropylene, polypropylene lined with polyethylene, and polypropylene lined with cloth bag, with 3 replications for each treatment. The data was analysed using Statistical Analysis System (SAS) and Two way analysis of variance (ANOVA) has been carried out to determine the independent variables and mean value were calculated using Least Significant Difference (LSD) test. The results revealed that seeds packed in polypropylene bags ( control) and with pavement drying recorded consistently higher germination rate (96%) under ambient condition. Parameters such as seed vigour index (1005.62), height of seedlings (12.21 cm) and root length (5.33cm) were also higher in comparison to those seeds stored in other packaging bags. Therefore the present study showed that others packaging bag which were PL-LDPE and PL-Cloth bag proved to be less effective for maintaining seed viability and vigour under ambient storage condition. Seeds that were dried using pavement drying and mechanical drying and packed with permeable packages (PL-control) were less subjected to the fluctuations of moisture. However, seeds dried using mat drying packed in impermeable packages will caused the seeds to respire and deteriorate faster. Lower moisture content helped to improve the storability of seeds attributable to the lower respiration rate, metabolic activity as well as lower infection of microorganisms. As a conclusion, paddy seeds variety TR-9 should be dried using pavement drying and kept in porous packages (PL-control) in order to maintain their viability and vigour under ambient condition.
