Experimental double hybrids of fresh corn grown under low and high phosphorus availability

ABSTRACT A serious problem in fresh corn growing regions is the low availability of phosphorus (P), especially Cerrado (Brazilian Savanna) biome. This study aimed to evaluate performance experimental double hybrids intended natura consumption grown under and high P availability. randomized blocks design was used, a 2 × 21 factorial arrangement, consisting two availabilities (37.5 75 mg dm−3 P2O5) hybrids, with 9 replications. The following variables were evaluated: ear insertion height, plant male female flowering, length diameter, grain weight, husked unhusked weight. best quality yield for market focused on observed DH94 DH102 DH71 DH81 hybrid performs better consumer market, regardless availability, and, therefore, has versatility aptitude this different technological levels.
