Optimizing rice yield through integrated agronomic management practices
Keywords:
agricultural yield, agronomic management, integrated management, rice, water-use efficiency.Abstract
Sustainable rice production faces significant challenges related to increasing food demand, limited water availability, soil degradation, and the need to improve agricultural resource-use efficiency. This systematic review aimed to analyse the available scientific evidence on integrated agronomic management practices used to optimise rice yield, considering water management, nutrient management, crop establishment, weed control, production diversification, and alternative production systems. Methodologically, a systematic review of 20 academic publications related to agronomic management and the productivity of rice-based systems was conducted. The information was organised into thematic categories to identify the main approaches, contributions, and trends within the analysed evidence. The results showed that yield optimisation depends on integrating practices adapted to the environmental and productive characteristics of each agricultural system. Alternate wetting and drying improved water-use efficiency; integrated nutrient management contributed to the effective use of soil fertility; and crop establishment, weed control, and diversification strategies strengthened the productivity and stability of rice systems. Furthermore, alternative production systems showed potential to improve both yield performance and agricultural sustainability. It is concluded that integrated agronomic management constitutes a relevant strategy for optimising rice production because it enables the coordination of different production practices, improves resource-use efficiency, and strengthens the capacity of agricultural systems to respond to contemporary environmental challenges.
