Figure 1
Number of pods (NOP) and grains (NOG) of the BRS Tumucumaque cowpea (Vigna unguiculata) cultivar as a function of the applied fertigation depths (A and C) and types of fertigation application (B and D), in 2022, in the municipality of Carpina, in the state of Pernambuco, Brazil. Different letters indicate significant differences between the types of fertigation application (pulse and continuous) by the Scott-Knott test, at 5% probability.

Summary of the analysis of variance for the yield variables of the BRS Tumucumaque cowpea (Vigna unguiculata) cultivar evaluated as a function of crop evapotranspiration (ETc) replacement depths and types of fertigation application, as well as of treatments with conventional fertilization and an irrigation depth of 100% of ETc, in 2022, in the municipality of Carpina, in the state of Pernambuco, Brazil⁽¹⁾.
