Abstract
This study was carried out at the Faculty of Sustainable Agriculture, Universiti Malaysia Sabah (UM5) Sandakan Campus from April 2014 to October 2014 to investigate• the effects of high application rate of NPK fertilizer (60:30:30, 100:60:60, and 150:90:90 kg ha-1) incorporated with high application rate of chicken manure (20, 40, and 60 t ha-1)on the growth and yield of TR-9 paddy variety grown on Beach Ridges Interspersed with Swales (BRI5) soil. Treatments were arranged as a factorial using complete randomized design (CRD) with three replications. Data collected was analyzed using two-way ANOVA at 5% significance level. The results showed that for vegetative growth of paddy plants, treatment T2 and 51 (100:60:60 kg ha-1 NPK incorporated with 20 t ha-1 chicken manure) produced the highest plant height which was 120.44 cm and 127.75 cm respectively. Treatment T2 and 52 (100:60:60 kg ha-1 NPK incorporated with 40 t ha-1 chicken manure) produced the highest tillers number of 42 and 45 tillers respectively. Treatment T2 and 51 (100:60:60 kg ha-1 NPK incorporated with 20 t ha-1 chicken manure) produced the highest number of culm height, which was 82.37 cm and 85.58 cm respectively. Treatment T1 and 52 (60:30:30 kg ha-1 NPK incorporated with 40 t ha-1 chicken manure) produced the highest percentage of productive tillers of 71.62 % and 79.37 % respectively. For yield components of paddy plants, treatment T2 and 52 (100:60:60 kg ha-1 NPK incorporated with 40 t ha-1 chicken manure) produced the highest number of panicles, which was 32 and 39 panicles respectively. Treatment T3 and 53 (150:90:90 kg ha-1 NPK incorporated with 60 t ha-1 chicken manure) produced the highest length of panicles, which was 24.57 cm and 25.95 cm respectively. Treatment T2 and 51 produced the highest percentage of filled grains (T2 = 74.60 %, 51 = 83.73 %) and extrapolated yield (T2 = 9.16 tons ha-1, 51 = 11.26 tons ha-1). Both treatment T2 and 51 also produced the least percentage of empty grains of 25.40 % and 16.27% respectively. Treatment T1 and 51 (60:30:30 kg ha-1 NPK incorporated with 20 t ha-1 chicken manure) produced the highest number in weight of 1000 grains which was 24.73 g and 25.81 g respectively. While for dry weight, treatment T2 and 51 (100:60:60 kg ha-1 NPK incorporated with 20 t ha-1 chicken manure) produced the highest number of 418.63 g and 464.44 g respectively. For BRI5 soil's chemical properties, treatment T3 and 51 (150:90:90 kg ha-1 NPK incorporated with 20 t ha-1 chicken manure) produced the highest soil pH of 5.36 and 5.91 respectively. Treatment T3 and 53 (150:90:90 kg ha-1 NPK incorporated with 60 t ha-1 chicken manure) produced the highest soil organic matter of 3.38 % and 3.57 % respectively. Treatment T3 and 53 also produced the highest number of soil total nitrogen (0.22 %, 0.25 %) and soil available phosphorus (1756.66 ppm, 2253.10 ppm). For soil exchangeable potassium, treatment T2 and 53 (100:60:60 kg ha-1 NPK incorporated with 60 t ha-1 chicken manure) produced the highest number which was 41.68 ppm and 59.01 ppm respectively. Treatment T1 and 53 (60:30:30 kg ha-1 NPK incorporated with 60 t ha-1 chicken manure) produced the highest number of cation exchange capacity of 180.44 cmolc kg-1 and 190.00 cmolc kg-1 respectively. Thus, it can be recommended that the treatment T2 and 51 is the best rate to be recommended to farmers because they produced the highest extrapolated yield. The second recommendation is treatment T1 and 52 because it showed the second best results as compared to treatment T2 and 51.
