EVALUATION OF MAIZE CULTIVARS AS TO YIELD OF GREEN AND DRY GRAINS

Nine maize cultivars, represented by seven double cross (AG-162, AG-30 2-A, AG-403-B, AG-5201, AG-303, AG-405 and C-525), one three-way cross (C-505), and one open-pollinated variety (Centralmex, used as control ) were evaluated both for ''green corn'' (grains with 70 or 80% humidi ty) and ordinary grain yield (GY) (dry grains). The green corn yield w as evaluated by total number (TNE) and total weight (TWE) of ears, num ber (NEHM) and weight (WEHM) of marketable ears with husk and number ( NEM) and weight (WEM) of marketable ears without husk. The cultivars w ere evaluated during three semesters in Mossoro, RN, Brazil. A randomi zed block design with five replications was used. There were not signi ficant differences among cultivars as TNE, NEHM and NEM. The semesters x cultivars interaction was significant for TWE, WEHM, WEN and GY. In general, for TNE and NEHM, the AG-5201 and AG-303 cultivars were the most productives. The C-505 cultivar was the best as WEM. The best cul tivars for GY were AG-302-A and C-505.
