Resumo: |
In the Northeast the area planted with soybean crop (Glycine max (L.) Merrill) quintupled over the past 22 years, with the major producing states Bahia, Maranhão and Piauí. In Garanhuns city the dairy business is composed of farming, animal husbandry and milk production, this activity the soybean contributes as a great source of nutrients and as a source of green fertilization, increasing the reservoir of soil nitrogen. The phytostimulant depending on their composition, concentration and proportion of substances, encourages plant growth and development, providing increased number of pods per plant and grain productivity. The technique of cutting offers significant yields green mass and dry matter, besides increasing the branches and number of pods per soybean plant, offering greater productivity. Aiming to identify the phytostimulant doses and cutting periods of soybean aerial part, with the purpose of provide within the same annual cultivation, biomass production and grain for producers the Wasteland Meridional de Pernambuco were studied three cutting periods and one treatment without cutting and association of phytostimulate doses, conducted in randomized block design in a split plots. The main variables of the vigor was the first count and percentage of emergency rescue and for the growth that stood out were net assimilation rate and the ratio and leaf area duration. The main observed variables were the green and dry biomass of the aerial part, the number of nodes and pods per plant after cutting and productivity of pods and grains. In this study, it was found that the two techniques can supply two products in a single cycle of soybean with biomass productivity of 7,037.44 kg ha-1 and 1,817.81 kg ha-1 grain. |
