Resumo: The phosphorus participates in vital processes in plants, such as photosynthesis, respiration, energy storage and transfer, cell division and cell growth. The potassium acts in the activation of some enzymes and plays an important role in the balance of water in plants. This study aimed to correlate the levels of phosphorus and potassium with productivity in irrigated rice as well as assess the feasibility of precision farming use in irrigated rice area. This experiment was conducted for three seasons in succession crops: rice, soybean and, rice, in Santa Vitória of Palmar / RS / Brazil. We used an area of 22.18 ha, divided into 15 portions, which were the center point georeferenced. A soil sample were collected from each plot consists of 9 sub-samples, which were sent to the Soil Analysis Laboratory of UFPel. Income and fertility maps were generated using data of soil analysis and productivity and created management zones with different fertilizer to correct and standardize the phosphorus and potassium. These results show that: precision agriculture provided increase of soil fertility through the management areas of use; the use of management zones decreased variability in phosphorus and potassium in the plots studied the block; there was no correlation between the levels of phosphorus and potassium in the yield of irrigated rice.

O potássio atua na ativação de algumas enzimas e desempenha um papel importante no equilíbrio de água nas plantas. O presente trabalho teve como objetivo correlacionar os níveis de fósforo e potássio com a produtividade em arroz irrigado, bem como avaliar a viabilidade do uso de agricultura de precisão em área de arroz irrigado. O trabalho foi conduzido durante três safras em sucessão de culturas: arroz, soja, arroz, no município de Santa Vitória do Palmar/RS. Utilizou-se uma área de 22,18 ha, dividida em 15 parcelas, as quais foram georreferenciadas no ponto central. Foi coletada uma amostra de solo em cada parcela, composta por 9 subamostras, que foram encaminhadas para análises químicas. Foram gerados mapas de rendimento e de fertilidade através dos dados das análises de solo e produtividade e criadas zonas de manejo com adubação diferenciada para corrigir e uniformizar os teores de fósforo e de potássio. Os resultados deste trabalho mostram que: a agricultura de precisão proporcionou aumento de fertilidade do solo através do uso de zonas de manejo; o emprego de zonas de manejo diminuiu a variabilidade nos teores de fósforo e de potássio nas parcelas do quarteirão estudado; não houve correlação entre os níveis de fósforo e potássio no rendimento da cultura de arroz irrigado.Universidade Federal de Viçosa - UFV2017-05-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/67310.13083/reveng.v25i2.749Engineering in Agriculture; Vol. 25 No. 2 (2017); 164-172Revista Engenharia na Agricultura - REVENG; v. 25 n. 2 (2017); 164-1722175-68131414-398410.13083/reveng.v25i2reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/673/448Leite, Cláudio WregeLuz, Carlos Alberto Silveira daLuz, Maria Laura Gomes Silva daGadotti, Gizele IngridNavroski, Renaninfo:eu-repo/semantics/openAccess2023-01-19T13:32:36Zoai:ojs.periodicos.ufv.br:article/673Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:32:36Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
