Abstract

A field study was conducted to investigate the potential of planting TQR-8 paddy variety on BRIS (Beach ridges interspersed with swales) soil which has poor physical and chemical properties and low fertility. This study was carried out at the School of Sustainable Agriculture rain shelter in Universiti Malaysia Sabah, Sandakan, located at latitude 50 55' N and longitude 118⁰ 02' E for four months (24th June to 25th October 2013). The objectives of this study were to determine the vegetative growth and yield component of TQR-8 paddy variety planted on a poor fertility BRIS soil and to evaluate the chemical properties of BRIS soil using soil amendments. In this study, various soil amendment treatments such as rice husk biochar, MG plus bio-organic fertilizer, MesraAlam Happy Farmer Bokashi, Agricare bio-organik and Sunray soil conditioner was incorporated with chemical fertilizer NPK (60 kg ha⁻¹: 30 kg ha⁻¹ : 30 kgha⁻¹) and one control NPK (90 kg ha⁻¹ : 60 kg ha⁻¹: 60 kg ha⁻¹). The application rate of the soil amendments was based on the factory recommendation. 18 clay pots of the dimension (30cm diameter X 35cm height) were used in this study with three replications for each treatment and were laid out using completely randomized design. The effect was measured through vegetative growth and yield component of paddy and the BRIS soil fertility after trial. The parameters of vegetative growth include plant height (cm), culm height (cm), number of tiller, and percentage of productive tillers. The yield component include number of panicle per hill, number of grains per panicle, percentage of filled grains, 1000 grains weight and extrapolated yield per hectare. Meanwhile, the parameter for the soil fertility taken before and after planting include pH of the soil, percentage of amount of nitrogen in the soil, concentration of phosphorus in the soil, concentration of potassium in the soil. Data were analyzed using one-way ANOVA. From the result there was significant difference among treatments in the plant height and number of tiller in the vegetative growth parameter. Meanwhile, there was significant difference in the yield component for number of filled grains, number of empty grains and extrapolated yield. The soil fertility showed significant difference in the percentage of nitrogen in the soil, concentration of phosphorus and concentration of potassium in the soil after the trial. Treatment two (T2) with the application of NPK fertilizer and rice husk biochar was found to give significant result in vegetative growth giving 99.40 cm plant height, 52.11 cm culm height, 22 tillers per hill, and 89.94% of productive tillers of paddy of variety TQR-8. In term of yield component, (T2) gave the significant result by giving 27 panicles per hill, 21.32 cm of panicle length, 63.27% of filled grains, 21.03 g of 1000 grains weight and extrapolated yield of 5.18 ton/ha. In term of soil fertility it improves the soil pH (4.37 to 5.28), nitrogen content (0.002% to 0.273%) and available phosphorus (4.56 ppm to 34.26 ppm). T2 had shown to have better supplement to inorganic fertilizer from the result discussed above. Thus, the application of 10 tons per hectare or 70.7 g per pot of rice husk biochar and chemical fertilizer (NPK) at the rate of 60 kg ha⁻¹:30 kg ha⁻¹:30 kg ha⁻¹ can be recommended to farmer who cultivate paddy on BRIS soil.
