Abstract
This study was carried out at the Faculty of Sustainable Agriculture, Universiti Malaysia Sabah, Sandakan Campus from April 2015 to October 2015 to evaluate the effect of different type of soil amendments incorporated with different application rates of chicken manure on the growth and yield of TR-9 paddy variety planted on Beach Ridges Interspersed with Swales (BRIS) soil and to evaluate the effect of different types of soil amendments and different application rates of chicken manure on nutrient content of the BRIS soil at the end of the experiment. Treatment were three soil amendments (nil (control), biochar and verrnicompost) and four chicken manure rates (0, 15, 30 and 45 t ha-1) that were arranged in complete randomized design with three replications. Data collected was analyzed with two- ways Analysis of Variance (ANOVA) at 5 % significance level. These results revealed that there was no significance effects of soil amendments and chicken manure rates on vegetative growth, yield components and BRIS soil chemical properties. There was a significant effect of soil amendments or significant effect of chicken manure rates on mean plant height (91.04 - 115.37 cm), mean number of tillers (26.22 - 38.11), mean culm height (63.45 - 75.69 cm), mean number of panicles (26.11 - 37.00), mean length of panicles (22.15 - 24.95 cm), mean percentage of filled grains (83.59 - 87.71 %), mean percentage of empty grains (12.31 - 16.40 %), mean weight of 1000 grains (25.28 - 26.22 g) and mean extrapolated yield (5.25 - 11.79 tons ha-1). There was no significant effect (percentage of productive tillers) on soil amendments and effect on chicken manure (66.59 - 77.60 %). There was also no significant effect (mean percentage of dry matter) on soil amendments and effect on chicken manure (61.79 % - 66.11 %). After application of different soil amendments incorporated with different chicken manure rates to BRIS soil, value for pH change from 4.46 to 4.30 - 5.49, soil organic matter change from 5.49 % to 5.20 - 5.67 %, soil total nitrogen increase from 0.167 % to 0.219 - 0.231 %, soil available phosphorus change from 1.27 ppm to 0.29 - 3.94 ppm, soil cation exchange capacity increase from 7.77 cmol(+) kg-t to 17.78 - 23.37 cmol(+) kg-t. Recommendations that can be suggested to farmers are biochar incorporated with 45 t ha-1 chicken manure (E2C4) and vermicompost incorporated with 45 t ha-t chicken manure (E3C4). This is because E2C4 gave highest mean extrapolated yield (E2 =9.91 tons ha-1, C4 = 11.79 tons ha-1), highest mean percentage of filled grains (E2 = 86.78%, C4 = 87.71%) and highest mean soil organiC matter (E2 = 5.62 %, C4 = 5.67 %).
