The editorial composition of number 3 of our journal in 2021 shows the range of topics and contents, clearly reflecting and you will see, the broad profile that it comprises since its inception. In these 48 years of uninterrupted edition, this serial publication of Agricultural Sciences can be considered the longevity and longest of all Cuban journals on this topic. This issue includes contributions on the common bean, tomato and sugarcane, three crops that have a preponderance in Cuban agriculture. Similarly, studies on heavy metals in soil contamination, nitrogen volatilization and the use of macroalgae as biostimulants show interesting results within the soil-fertility universe. Contributions on the conservation of botanical heritage, the phytochemical characterization of weeds and the scarification of Clitoria ternatea seeds complete this number within the study on Cuban flora. The latter, as a tribute to the Villa Clara Botanical Garden, which next October will be 65 years old after its creation.
With the best hope that these contributions serve our readers to increase their agricultural cultural heritage.
