Effect of indigenous organic fertilizer on the growth and yield of paddy

Abstract

The utilization of organic fertilizer (OF) is one of the solutions to reduce the negative impact of inorganic fertilizer (IF). OF can maintain soil fertility and quality that also increases farm yield. This research aimed to analyze the effects of various fertilizer, including IF and OF from indigenous source, on the growth and yield of paddy. The experimental method used Randomized Block Design Pattern with five treatments, consisted of: 1) no fertilizer (control); 2) IF; 3) cow manure compost (CMC), 4) indigenous organic fertilizer (IOF); and 5) commercial fertilizer (CoF). All treatments were replicated four times. The daya were analyzed statistically by the F test, followed by the Duncan Multiple Range Test at the level of 95%. The results showed that various fertilizer treatments did not resulting significant difference on plant height, 1000 seed weight, and grain yield but resulting significant difference for tillers number at day 14, 21, 28, 35, 44, 50, 57, 64, 70, and 80 and panicles number at day 86, 93, and 99. The grain yield with IOF is 1.8% higher than control and 4.9% higher than IF. Our results highlight the benefit of OF utilization from indigenous sources that available around us.
