The research objective is to analyze the subsidized fertilizer price (HET) at the hand of farmers of rice farming in South Sumatra province. The sampling method was disproportionate stratified random sampling with four land typologies. The field data were collected through observation, and interviews with respondents. The use amount of fertilizers on all typologies effected significantly different to rice yields. In the lebak ricefields, the influence of Urea, NPK Phonska and KCl together effected significantly different, but not significantly different for each use of fertilizers. The use cost of Urea affected rice yields and income of farmers significantly different for all ricefields. Eligible HET price received by farmers has to be lower than the real HET price. Determination eligible HET price has to consider soil productivity and accessibility (dam, water gates, water pump, road, infrastructure, local retail and others).

This paper aimed to find novel innovation and research of subsidized fertilizers based on soil nutrient variability and farmer's perception in rice farming. This study uses a completely randomized design with four natural treatments, a one-way Anova and Tukey HSD Test as well as multiple linear and cubic regressions. The fertilizer uniformity on varied ricefields was a big failure because it causes fertilization becoming ineffective, inefficient and unsustainable. Ricefield variability (due to geomorphogenesis, pedogenesis, interflow flow, vegetation distribution, land use patterns, and fertilizer application) causes not optimized fertilization (dose, balance, time, methods of fertilization). The perception of farmers can create conflicts of interest, which are determined as normal, unavoidable and natural. Shortterm research target is how fertilization in the field is done effectively, efficiently, and sustainably, whereas long-term target is to generate new sources of wealth, fertilization technology based on soil science knowledge, forming professional researcher, the great inventions of patents, cooperation media between scientists, technocrats and bureaucrats and research funding.
