Implementation of Rice and Maize Cultivation Technology Based on Agronomic Effectiveness

摘要

The existing land characteristics and inappropriate management during intensive agricultural practice on upland, swampland, and paddy field are the factors that causing land productivity to be low and decreasing. Alternative efforts to increase the land, rice, and maize productivities could be carried out through the implementation of Site- Specific Nutrient Management technology based on the RAE parameter. This paper presents thoughts on the opportunities for refocusing RAE- based research on agricultural cultivation technology, and research results that have been done.The research of rice and maize with RAE in the upland and paddy field has resulted in a location-specific cultivation technology package. The technologies that have been produced are single NPK inorganic fertilizer package, the combination of single NPK- compound NPK inorganic fertilizers, the combination of single NPK inorganic fertilizer-organic fertilizer, and combination of single NPK inorganic fertilizer-biofertilizer. By using RAE value, these researches have shown a more effective technology package in comparison with standard technology. The technology devices for determining standard fertilization needed to support the research with RAE parameter as the basis are available. The said devices are Upland, Swampland, and Paddy Soil Test Kit. Refocusing research of location-specific fertilization that explicitly using RAE parameter is relevant to promote sustainable agriculture.
