Abstract

Different arrangements between plants make it possible to optimize
the use of natural resources available in corn production, achieving better yield. Thus,
this work aimed to evaluate some productive traits of the crop in different spatial
arrangements. The leading production indicators of the corn were evaluated at the
Experimental Farm of the São Paulo State University (FCAV – UNESP), campus
in Jaboticabal – SP, Brazil—the statistical design in randomized blocks, with four
replications. The treatments corresponded to 2-row spacings (single-row with 0.90m
and twin-rows, interspersing spacing of 0.45m and 0.90m) and three plant populations
(55,000, 60,000 and 65,000 plants ha -1), composing a 2 x 3 factorial. Confirmatory
and descriptive statistical analyses were carried out, and the statistical process control
constructed control charts. Twin-row spacing showed the best results for yield and
height of the first ear. The 65,000 ha-1 population stood out for its lower data variability
(smaller amplitude), providing more excellent quality in corn grain yield through spatial
optimization of available resources.
