Produtividade do milho em função da densidade de plantas e posicionamento das sementes no sulco de semeadura

Abstract

The yield of maize crop can be compromised by several Factors, be they, phytopathological, edafoclimatic, among others. However, Correct and precise management of the culture, since its implantation, using Adequate densities and spacing, until the time of maturation and Harvesting, are essential to achieve high production ceilings. Considering a high level of investment, it is possible to increase the seeding. This, together with the positioning of the seeds in the Sowing, which in addition to having spacings equidistant from all Favors their development and reduces intra-specific competition. In addition, in the post-emergence period, leaves must This behavior, all located in the space between lines, thus having Greater absorption capacity of solar radiation, increasing its solar Photosynthetic and as a consequence, raising productivity. Therefore, the The objective of the present experiment was to increase productivity in These two factors. And for that, in the parcels containing seeds The sowing was all manual, so that this evaluation was possible. In the others, the planting was done in a traditional way, that is, Tractor-seeder set. Already the cultural treatments and cover fertilizations, As well as in the harvesting process, the method used was all manual. The Results were satisfactory in relation to productivity, and feasibility was verified in the production of plots with populations of 90,000 Plants / haˉ¹, reconciled with the method where the seeds were positioned In the sowing groove.
