Nutrição foliar com micronutrientes, macronutrientes e reguladores vegetais na cultura da soja

Abstract

The foliar plant nutrition, is the supply of nutrients such as nitrogen (N), phosphorus (P), magnesium (Mg), boron (B), copper (Cu), molybdenum (Mo), zinc (Zn), cobalt (Co ) and also plant hormones such as auxin (Ax), cytokinin (Ci) and gibberellin (Gb). This study aimed to evaluate the foliar nutrition efficiency macro, micronutrients and plant growth regulator of the production parameters. The experiment was conducted in the field Celeste farm on the shores of the BR - 163 in the municipality of Vera - Mato Grosso. For the experiment was used to cultivate TMG 4190. Delineation randomized blocks, with eleven treatments and four replications. Treatments: T1 (TS: Masterfix® V4: CoMo Platinum); Treatment 2-11 all received (TS: Masterfix® V4: CoMo Platinum + Stimulate®; R1 / R2: Stimulate®); Treatment 3-11 all received doses of Mover® + Stimulate® R5.3 in that same stadium Treatment 4 received application FRC PM, and treatment 5-8 received increasing doses of Stoller Mg® (0.5 L ha 1; U 1 h-1, h 2 G-1, G 4 h-1). The treatments 9.10 and 11 dose of 1, 2 and 4 h-1 L Stoller Mg® were splitted between R3 / R4 and R5.3. Parameters assessed: plant height, first pod height, number of pods per plant, number of seeds per pod, weight of 100 grains and productivity. Data were submitted to analysis of variance and means were compared by Tukey test (p <0.05). There was no significant difference between treatments, but there was an increase in productivity of most treatments.
