Three experiments were conducted with the objective of studying the effect of palm oil mill effluent POME on the yield of cabbage in Cameron Highlands. In the first and second experiments POME were tested with and without inorganic fertilizer. The 3rd experiment consisted of POME applied in furrows with varying levels of NPK. All three experiments were arranged in a Randomised Complete Block Design with three replications. In the first experiment where POME was broadcast the yield did not increase significantly when POME was increased from 20 to 80 t/ha. In the 2nd experiment where POME was applied in furrows higher levels of POME gave significantly higher yields. POME at 20 t/ha and chicken manure CM at 20 t/ha gave similar yields indicating that POME can be substituted for CM. Increasing POME levels in experiment 1 gave a quadratic yield response for the residual crop. In experiment 2 the yield response was linear for both the crops while in experiment 3 aquadratic yield response was obtained for the main crop and a linear response for the residual crop. Mean marketable yields obtained for the main crops were 31.9 25.5 and 27.2 t/ha for experiments 1 2 and 3 respectively. Results obtained for the residual effect of POME showed yield reductions of 23 and 47 in experiments 1 and 2 respectively. Soil N values ranged from 0.08 to 0.15 at the end of the main crop and 0.07 to 0.19 at the end of the residual crop. Soil C values ranged from 1.23 to 1.81 at the end of the main crop and 1.01 to 1.21 at the end of the residual crop in experiment 3.

Abstract

Three experiments were conducted with the objective of studying the effect of palm oil mill effluent POME on the yield of cabbage in Cameron Highlands. In the first and second experiments POME were tested with and without inorganic fertilizer. The 3rd experiment consisted of POME applied in furrows with varying levels of NPK. All three experiments were arranged in a Randomised Complete Block Design with three replications. In the first experiment where POME was broadcast the yield did not increase significantly when POME was increased from 20 to 80 t/ha. In the 2nd experiment where POME was applied in furrows higher levels of POME gave significantly higher yields. POME at 20 t/ha and chicken manure CM at 20 t/ha gave similar yields indicating that POME can be substituted for CM. Increasing POME levels in experiment 1 gave a quadratic yield response for the residual crop. In experiment 2 the yield response was linear for both the crops while in experiment 3 aquadratic yield response was obtained for the main crop and a linear response for the residual crop. Mean marketable yields obtained for the main crops were 31.9 25.5 and 27.2 t/ha for experiments 1 2 and 3 respectively. Results obtained for the residual effect of POME showed yield reductions of 23 and 47 in experiments 1 and 2 respectively. Soil N values ranged from 0.08 to 0.15 at the end of the main crop and 0.07 to 0.19 at the end of the residual crop. Soil C values ranged from 1.23 to 1.81 at the end of the main crop and 1.01 to 1.21 at the end of the residual crop in experiment 3.
