Resumo:
With the objective of evaluating the agronomic characteristics of the corn
crop sowed in three tillage systems with two spacing among lines. He settled an
experiment in area of the Department of Rural Engineering FCAV - Unesp, Campus of
Jaboticabal-SP. The experimental was maybe accomplished in blocks at random with 4
repetitions, being the tillage systems: conventional (with moldbordplow and grating),
reduced (with chiselplow conjugated to roll destorroador and cut disk) and no tillage;
being combined with two spacing among lines for the culture of the corn: 0,45 and
0,90m. The tillage did not influence the initial stand and medium number of days for
emergency, diameter of the stalk and productivity of rasp on culture of the corn. The
productivity of grains and the height of the plants were larger for the spacing 0,45m,
demonstrating that in this spacing happened better arrangement of the plants.
