ASSESSMENT OF THE EFFECTS OF COMPOSITION FROM THE SLUDGE OF SNAKEHEAD FISH POND ON THE GROWTH AND YIELD OF AMARANTHUS L.

Abstract

This study was conducted to evaluate the effects of organic fertilizers made from sludge snakehead ponds on growth and yield of amaranth plants. The vegetable growing experiment was arranged in 5 treatments with 3 repetitions using combination of inorganic and organic according to the ratio: 100% inorganic fertilizer (control), gradually reducing to 75%, 50%, 25 % and 0%. The results showed that the growth of amaranth plants after 30 days of planting reached an average height of 30.8cm in the dry season and 30.9cm in the rainy season. The average vegetable production in the dry season was 6.7 tons/ha and 6.8 tons/ha in the rainy season. In which, the highest yield in treatment 3 was 6.9 tons/ha in the dry season and 6.95 tons/ha in the rainy season.
