The opposite happened in the dry season months, alerocanthus Octuber presented the higher C 0 values. In the MPS, except for February, which the linear modelfitted the data, for all the other evaluations data of both systems, d the spherical and exponential models had a good fit.
Studies indicate that diversification practices such as intercropping in the northeast region are beneficial because these practices reduce pest damage [ 41 ]. Revista Cultivar 7 Plant pests of quarantine importance to the Caribbean.
