Abstract

THE OBJECTIVEOFTHISWORKWASTOIDENTIFYTHEBEST DOSE OF P IN MAIZE (ZEAMAYS). THE EXPERIMENTWASCARRIED OUT ATTHEPRESENTSETTLEMENTFARMOFGOD, GOIAN�SIA-GOI�S. THE EXPERIMENTAL DESIGN WAS A RANDOMIZEDBLOCKWITHFIVETREATMENTSANDFIVEREPLICATIONS. P / HA-1 (V1 WITNESS), 60 KG P / HA-1 (V2), 90 KG P / HA-1 (V3), 120 KG OF P / HA-1 (V4) AND 150 KG OF P / HA-1 (V5). THE MORPHOLOGICALCHARACTERISTICSEVALUATEDWERE: PLANTHEIGHT, STALKDIAMETER, FIRSTEARHEIGHT, EARDIAMETER, NUMBEROFROWS IN EAR, NUMBEROFGRAINS PER ROW, DRYMASSANDGREENMASSOFPLANTANDEAR. IT WASVERIFIEDTHATTHEFERTILIZATIONOF P IN THETREATMENT V1 TO V4 HADANINCREASE IN THECORNPRODUCTIONAND IN THETREATMENT V5 THEREWAS NO INCREASE, IN THE CASE OF SOME MORPHOLOGICALCHARACTERISTICS, AS ROWNUMBEROFGRAIN, EARDIAMETER, WHICHHADINCREASEDWITHTHETREATMENT V5, 150 KG OF P / HA-1. THUS, BYTHE DATA OBTAINED, THEMOSTUSED DOSE FOR MAIZEPRODUCTIONAND V4 TREATMENT.
