Jorge Atílio Benati; Gilberto Nava; Newton Alex Mayer Revista Brasileira de Fruticultura 2021. doi:10.1590/0100-29452021093
Other claims from this paper (4)
- Intervention effect Peach SPAD index rose linearly with soil nitrogen rate.
- Association SPAD index correlated positively and linearly with peach leaf nitrogen, with yearly correlations of 0.652, 0.756, 0.762 and 0.767.
- Method / resource SPAD can diagnose peach nitrogen status when measured 13 to 15 weeks after full bloom.
- Method / resource SPAD values of 39 to 49 indicate normal peach leaf nitrogen of 33 to 45 g kg-1.
