Abstract

Intensive Pangasius aquaculture farming contributes to increased income and profits in Vietnam, but is also associated with many environmental problems, including pollution from nutrient-rich water and sediments that are released into the environment. This article investigates the feasibility of using Pangasius pond sediments (PPS) in combination with amendments of rice straw (RS) to fertilize cucumber (Cucumis sativus L.) and water spinach (Ipomoea aquatica Forssk) plant. The results showed that mixing a ratio of 30% PPS with 70% RS produced the highest nutrient concentrations. The study demonstrates that organic fertilizer produced from PPS in combination with chemical fertilizer can replace 2575% of the inorganic fertilizers used as a nutrient source for cucumber and water spinach, and also increase the vegetable production. The highest yields were found for treatment PPS-3 (a combination of 50% chemical fertilizer and 50% organic fertilizer used on cucumber), and for treatment PPSRS-4 (a combination of 25% chemical fertilizer and 75% organic fertilizer used on water spinach) in both the wet and dry season (P˂0.05). The lowest yields were found when growing cucumbers and water spinach either with 100% organic fertilizer (the treatment PPS-5) or with 100% chemical fertilizer (the control treatment PPS-1), respectively (P˂0.05). Overall, the results indicated that the recycling of PPS as organic fertilizer and chemical fertilizer in combination for vegetable cultivation is more environmentally friendly as compared to using only chemical fertilizers.
