CORTEZ, Jorge Wilson et al. Evaluation of the influence of vertical loads on different press whels in the cycle of sowing of the corn. Ciênc. agrotec. [online]. 2007, vol.31, n.4, pp.1155-1160. ISSN 1413-7054.  https://doi.org/10.1590/S1413-70542007000400031.

As well as other cultures of tropical origin, the corn demands during vegetative cycle, heat and humidity to develop, and the conditions of installation of the culture can define a good or bad yield. The objective of this work was to evaluate the influence of vertical loads on press wheels in the cycle of the culture of the corn. This work was driven at Faculdades Associadas de Uberaba - FAZU, in the municipal district of Uberaba (MG), and installed in randomized blocks design with three models of press wheels and three vertical loads with two repetitions, in the Track of Rehearsals of Sowing, constituted of soil channels. Observed that the number of days for emergency, height of plants, number of leaves and the yield were not affected significantly for the studied treatments.
