- Abstract
The aims of the current study are to evaluate the yield of sweet corn cultivars and to define the most favorable sowing date for crop development in Cáceres County - MT. The experiment has followed a randomized block design, with factorial arrangement 5x2 and four repetitions. Five sweet corn cultivars (AG 1051, AG 4051, BM 3061, RG 01 and Cativerde 02) sown at two different sowing dates (December 30, 2013 and January 29, 2014) were evaluated. The following parameters were assessed: plant height; ear insertion height; ear (with and without husk) length, diameter and weight; percentage of marketable green ears; cycle and thermal sum (in GD - degrees day) between green ear emergence and harvest. The highest plant height and ear insertion values were observed in plants grown on December 30. Hybrids 'BM 3061' and 'RG 01' were harvested in the shortest cycle and, consequently, they required lower thermal sum. BM 3061, AG 1051 and AG 4051 were the most productive hybrids; therefore, they were the most suitable for cultivation. Plants sown in December recorded the best yield rates.
