Soybean development and thermal requirement under the climatic conditions of Paragominas, Pará state, Brazil
2013
Revista de Ciências Agrárias
The degree-days or thermal time theory has been widely used to simulate crop development because of its simplicity; in addition, it represents a good indicator of crop phenological evolution compared with the days after sowing scale. We investigated the development and thermal requirements of soybean (Glycine max (L.) Merrill), BRS Tracajá cultivar, grown in an agricultural border area of advance in eastern Amazon. The field experiment was carried out in the 2007 and 2008 growing seasons in the
