Así lo destaca Diego Golombek, científico y divulgador para quien comunicar la ciencia requiere rigurosidad y aprovechar al máximo los recursos disponibles, como la ficción y el humor. En un tono reflexivo evalúa el rol de la comunicación institucional y, además, plantea que el desafío actual de la educación técnica es “mantener lo bueno y avanzar hacia lo nuevo”.

Pearl millet’s spatial organization impact on halo-hydromorphic environments
The capture of resources by different species is conditioned to a large extent by their availability in the environment and by the distribution of individuals in space, the latter can be modified from different combinations of rows spacing and seeding rate. The objective of the work was to determine with what spatial arrangement the best establishment and growth of pearl millet biomass in halo-hydromorphic environments is obtained. Thus, during the establishment stages, the increase in seeding rate of pearl millet increased the density of individuals (plants.m-2), up to densities of 18 kg.ha-1, during the early establishment (450ºCd), diluting to the first growth (750ºC), finding a plateau in the density of tillers with seeding rate of 12 kg.ha-1, finding no difference between the densities used in the second growth (1450ºC). No differences were found during the early growth in the size of individuals or in the biomass accumulated between the different seeding rate used, nor were differences found in the density of plants during the early establishment for the different rows spacing, finding later in both accumulations, those treatments planted at a greater distance between rows (40 cm) had greater accumulated biomass and weight of their yield components, compared to those planted with less spacing (20 cm), not being recommended for pearl millet to reduce rows spacing in environments with water and salt limits.
Keywords: establishment, row spacing, seeding rate, halo-hydromorphic soils.
