Abstract

A field experiment was conducted in the net house of Faculty of Sustainable Agriculture, Universiti Malaysia Sabah, Sandakan from 12 April 2014 to 12 September 2014 to study the effect of high application rate of NPK incorporated with high rate of chicken manure on TR-9 rice variety growth and yield in Silabukan soil and to evaluate Silabukan soil nutrients (NPK, CEC, pH and organic matter) after application of NPK and chicken manure. The experimental design was completely randomized design (CRD) with three replications. Three rate of NPK (T1=60:30:30, T2=90:6O:60 and T3=120:90:90 kg ha-1) and three rates of chicken manure (C1=20, C2=40 and C3=60 ton ha-1) were tested. Results revealed that interaction of NPK and chicken manure on TR-9 rice variety growth and yield was not significant. In term of NPK, treatment T3 had the highest plant height (135.16 cm), percentage of productive tillers (85.72 %), number of panicles (44.89), percentage of filled grains (86.50 %) and extrapolated yield (12.71 ton ha-1). In term of chicken manure, treatment C3 was the highest in number of tillers (53.06), percentage of productive tillers (87.96%), percentage of dry matter (53.38 %), number of panicle (48.61) and extrapolated yield (13.08 ton ha-1). For soil analysiS, both treatment T3 and C3 had the highest soil pH (5.30; 5.29), total nitrogen (1.39 %; 1.35 %), available phosphorus (1639.53 ppm; 2809.54 ppm), potaSSium content (39.87 ppm, 49.29 ppm), and CEC (28.18 cmole kg-I; 27.19 cmole kg-1). Results suggested that the application of NPK at the rate of 60:30:30 kg ha-1 and chicken manure 60 ton ha-1 gave the highest mean tiller number (55.5), panicle number (50.17) and extrapolated yield (13.66 ton ha-1), followed by 120:90:90 kg ha-1 NPK and 60 ton ha-1 chicken manure.
