Abstract

This experiment was carried out based on a completely randomized design with three replications and two factors by applying a type of bed (manure, manure plus superabsorbents nanocamposite and vermicompost plus superabsorbents nanocamposite) and irrigation period (no stress, 5-day and 10-day) in the farm. Shoot and root height, fresh and dry weight, chlorophyll content, root penetration depth, carbohydrate, chlorophyll, prolin, carotenoid and ion leakage cnotents were measured in this experiment. The results showed that the bed containing nanocomposite superabsorbent was significant on fresh weight, dry weight and root penetration depth. The effects of irrigation period were significant on fresh weight, dry weight, root penetration depth, chlorophyll b, chlorophyll, carbohydrate, electrolyte leakage and quality (NTEP). The quality was maintained in five-day irrigation period. The interaction between bed and the irrigation period was significant for proline and Chlorophyll which indicating the tolerance of five-day irrigation period in the bed containing superabsorbents nanocomposites.
