Dear colleagues, the journal Centro Agrícola begins 2018 in volume 45. Interesting results on the efficacy of six fungicides in the control of Mycosphaerella citri, the morphophysiological and productive indicators of the pepper, and the evaluation of Sugar Cane genotypes in different environments are exposed in it. Subjects as diverse as the biological response of Azospirillum spp. to stress, the report of Procontarinia mangiferae on mango in Cuba, the effect of flours of Gossypium hirsutum and Ricinus comunis on Brassica oleracea, the effectiveness of FitoMas-E in chickpea, the combined application of chemical fertilizer and earthworm humus in Capsicum annuum, as well as the alternation of crops and their effect on the soil, can also be found in this issue. As something new to highlight, a review of the potential of medicinal plants in the control of spontaneous species is suggested. The content of this issue closes a brief communication evaluating cucumber hybrids in crop houses.
