Productivity of the rice granary areas of Peninsular Malaysia showed instability in production trends over the past 20 years. Current average yield is 4.0 t/ha. The new yield target as set by National Agriculture Policy 3 NAP3 is 7.0 t/ha. It is noted that there is disparity in yield performance between and within granary areas. Benchmark studies conducted recently indicated that yield performance is very much affected by changes in farming practices such as the adoption of direct seeding over reliance on contract service operators and intensive and indiscriminate use of agro-chemical inputs. At the same time the significant role of fertilizers to boost yield performance through fertilizer subsidy scheme has long been recognized. However the changing farming practices creates interferences into the functional role of fertilizers as yield enhancer thus the ;single component attribute; perception has to be viewed in broader spectrum in relation to the interactive contribution of fertilizer management together with other determinants of yield performance. This paper provides an insight into the complexities of fertilizer management practices in double cropping rice farming. A case study in MADA using precision farming approach is used as an illustration to demonstrate the interactive dependence of production factors to improve effectiveness of input use particularly fertilizers to enhance yield performance in rice production.

Abstract

Productivity of the rice granary areas of Peninsular Malaysia showed instability in production trends over the past 20 years. Current average yield is 4.0 t/ha. The new yield target as set by National Agriculture Policy 3 NAP3 is 7.0 t/ha. It is noted that there is disparity in yield performance between and within granary areas. Benchmark studies conducted recently indicated that yield performance is very much affected by changes in farming practices such as the adoption of direct seeding over reliance on contract service operators and intensive and indiscriminate use of agro-chemical inputs. At the same time the significant role of fertilizers to boost yield performance through fertilizer subsidy scheme has long been recognized. However the changing farming practices creates interferences into the functional role of fertilizers as yield enhancer thus the ;single component attribute; perception has to be viewed in broader spectrum in relation to the interactive contribution of fertilizer management together with other determinants of yield performance. This paper provides an insight into the complexities of fertilizer management practices in double cropping rice farming. A case study in MADA using precision farming approach is used as an illustration to demonstrate the interactive dependence of production factors to improve effectiveness of input use particularly fertilizers to enhance yield performance in rice production.
