Intercropping and Nitrogen Fertilization Altered the Patterns of Leaf Senescence in Sorghum

Figure 3

Peak leaf greenness (SPADmax) of two sorghum varieties (Gadam and Serena) grown in sole and intercrop system with two varieties of cowpea (K80 and M66) and interactions with 0, 40, and 80 kg N ha⁻¹ at the KALRO research stations in Igoji (a) and Katumani (b) during 2018/2019 short rains. Mean values followed by the same letter are not significantly different. The bars indicate the mean standard errors (SE).
