The field experiment was conducted to study microbial product and urea effects in decomposing rice straw on the growth and yield of rice grown in acid sulfate soils in a three rice cropping system, at Tam Nong district, Dong Thap province, in the Autumn-Winter crop of 2016. The experiment was carried out in factorial design with 2 factors in randomized complete blocks with 3 replications. | Effects of microbial products and urea in biodegradable rice straw on the growth and yield of rice in acid sulfate soils, Đong Thap province AGU International Journal of Sciences – 2019, Vol 7 (3), 91 – 98 EFFECTS OF MICROBIAL PRODUCTS AND UREA IN BIODEGRADABLE RICE STRAW ON THE GROWTH AND YIELD OF RICE IN ACID SULFATE SOILS, DONG THAP PROVINCE Mai Vu Duy1, Nguyen Bao Ve1, Nguyen Thanh Hoi1, Nguyen Thanh Tai2 1 Can Tho University 2 Dong Thap Department of Science and Technology Information: ABSTRACT Received: 08/03/2019 Accepted: 11/06/2019 The field experiment was conducted to study microbial product and urea Published: 11/2019 effects in decomposing rice straw on the growth and yield of rice grown in acid sulfate soils in a three rice cropping system, at Tam Nong district, Keywords: Dong Thap province, in the Autumn-Winter crop of 2016. The experiment Urea, Trichomix-DT, was carried out in factorial design with 2 factors in randomized complete TricôĐHCT-Lua von, Dascela, yield of rice, acid sulfate soil. blocks with 3 replications. The first factor - treatment of Urea- included: (1) untreated (2) treated with Urea. The second factor - type of microbial products- included (1) untreated, (2) treated with Trichomix-DT, (3) treated with TricôĐHCT-Lua von (4) treated with Dascela. The results showed that incorporporation of rice straw treated with Dascela increased the number of full grains per panicle (78 fully grains per panicle), the number of panicles per m2 (447,7 panicle /m2) and grain yield (5,95 t/ha). The combination of rice straw treated with Dascela and Urea increased density of Cellulomonas flavigena bacteria and the number of tillers per m 2. Urea treatment increased density of Cellulomonas flavigena bacteria. 1. INTRODUCTION implement it. Therefore, to reduce the labor of Organic poisoning usually occurs on intensive farmers in the straw incubation, the hypothesis farming land, due to the .
