Nitrogen uptake in lentil cultivar mixtures is not predictable from pure stands performance but is correlated with agronomic parameters and experimental conditions

Table 3 Result of the correlation analysis between the parameters observed in this study and the agronomic parameters of Lorenzetti et al. [29]
