A evolução das produtividades de arroz irrigado em função do manejo agronômico no estado do Rio Grande do Sul

Abstract

Rice is highlighted both economically and socially in the state of Rio Grande do Sul, where it is cultivated in several lowland areas and in a flood irrigation system. It is of great importance in the southern half of the state as a primary source of income for more than 128 municipalities based on irrigated rice cultivation. The state of Rio Grande do Sul is responsible for a large part of the Brazilian production of rice, totaling 73%, occupying around 66% of the national area, being the state that most produces this cereal. The present work aims to highlight the evolution of irrigated rice yields in the state of Rio Grande do Sul. This advance in rice productivity in Rio Grande do Sul has a history that demonstrates the importance of Instituto Rio Grandense do Arroz (Irga) in these advances. The different techniques of soil management and crop fertilization can present a different scenario than expected, so we have that one of the ways to increase rice crop productivity is to carry out an adequate fertilization management. The work allowed us to establish an analysis of rice production in the state of Rio Grande do Sul and analyze the increase in productivity. You have as a contribution that from this study you can allow other works to add and thus contribute to the decision-making of the producers. The favorable point was the highlight in rice production in the last 50 years, the state of Rio Grande do Sul obtained a significant increase in relation to its production and productivity, this factor demonstrates that the state is on the right track with large studies leading to this increased productivity.
