Growth, Development, and Water Consumption of Irrigated Bean Crop Related to Growing Degree-Days on Different Soil Tillage Systems in Southeast Brazil

Table 2

First degree equation () relating the accumulated dry matter of the bean crop (g m⁻²) to the thermal time (degree-days) for soil tillage systems (STS): chisel ploughing (CP), disk ploughing (DP), and revolving hoe (RH), during the linear growth stage, in Campinas city, São Paulo state, Brazil.
