Phosphorus calibration analysis for rice crop in greenhouse

Phosphorus calibration analysis for rice crop in greenhouse

Soils of Central Brazil in their native state are deficient in phosphorus. Te obtain high productivity in these soils, application of P is essential. There is limited information about P calibration in soils for rice crop. Therefore, a greenhouse experiment was conducted to establish correlation between P-test in soil and productivity utilizing three rice cultivars (IAC 47, IAC 164, IR 43). Critical P level in the soil studied varied between cultivars and with the stage of development. Soil test rating for P is presented for each cultivar at different growth stages. These results can serve as a guide for greenhouse experiments utilizing rice as a test crop.

Para se obter alta produtividade nesses solos, á necessário que se faça adubação fosfatada. Como existe pouca informação sobre a calibração de análise de P para arroz, foi conduzido um experimento, em casa de vegetação, a fim de estabelecer a correlação entre o teor de P no solo e a produção de matéria seca da parte aérea da planta, utilizando-se três cultivares (IAC 47, IAC 164 e IR 43), em diferentes estágios de crescimento. Os níveis críticos de P no solo, em relação à produção relativa, variaram entre cultivares e estágios de crescimento. A classificação de teor de P foi apresentada para cada cultivar, em diferentes estágios de desenvolvimento da planta, e pode servir de guia para experimentos em casa de vegetação com a cultura do arroz.
