Summary: | 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. |
