This initial exercise was to determine the paddy yield response functions with fertilizer application on a Malaysian soil in order to incorporate the economic consideration of the Malaysian fertilizer cost and paddy price variations. The yield response cur fertilizer could be described by a quadratic equation and this can be used in fertilizer rate prediction. The fluctuating fertilizer costs and paddy prices were used to estimate the economic fertilizer rate. It was found that the economic ferti fertilizers without subsidy were 130.96kg/ha, 41.57kg/ha, 64.20kg/ha respectively for the chosen soil types. The simulation revealed that the economic fertilizer rate and maximum profit were influenced by the current fertilizer that subsidies were not given for the fertilizers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
