Abstract

ABSTRACT Lodging of rice plants in paddy fields can reduce yield and cause economic loss to the farmers. A field experiment was conducted at the Faculty of Sustainable Agriculture (FSA) located at University Malaysia Sabah, Sandakan, Sabah to study the effect of silicon and high nitrogen fertilizer on the growth and yield of Serendah Merah rice variety and to study the effect of silicon in reducing the lodging effect on Serendah Merah rice variety. The experimental design used was Factorial Completely Randomized Design (CRD) by using 60kg/ha, 120kg/ha and 180kg/ha of Nitrogen fertilizer and 0kgha·1, 200kgha·1 and 400kgha·1 of the silicon fertilizer. This experiment had three replications in each treatment. Data were analyzed with two-way analysis of variance (ANOVA) by using Minitab 16 Statistical Analysis Software. The means were compared at P<0.05 by using Tukey's test. The results revealed that application of 180kg/ha N contributed to the maximum culm diameter (10.11mm), panicle length (24.2cm), number of grains per panicle (113), number of filled grains per panicle which were 77 (68.14%), number of empty grains per panicle which were 37 (32.74%), leaves dry weight (14.06g) and stem dry weight (10.16g). However, application of nitrogen at the rate of 120kg/ha produced the highest 1,000 grains weight (27.09g), highest root dry weight (33.Slg) and also highest extrapolated yield (5.42 tons/ha) but showed no significant effect between nitrogen rates. In the case of silicon, the largest culm diameter (10.29mm) was from 400kg/ha Si. Although there were no significant differences for the interaction between N and Si on all yield parameters, the highest Si rates, 400kg/ha, showed a significant effect on culm diameter in order to reduce lodging incidence. In order to strengthen the culm of the rice plant, application of silicon fertilizer is recommended. Additionally, more studies on growth and yield of Sabah traditional rice varieties need to be carried out to contribute the knowledge about the effect of nitrogen and silicon fertilizer to increase yield and income to the farmers.
