Desempenho agronômico da soja em função de doses Dek em solo com baixo teor do elemento

Abstract

This study was developed with the objective of evaluating a soy RESPONSE to potassium doses no system soybean / corn in soil with lack of K. The experiment was Held in the 2013/14 crop in Sorriso-MT. The experiment was installed with five treatments block diagram Randomly applying the doses of K2O (0; 40; 80; 160; 320 kg ha -1 ) in no time surface sowing. As portions were 12 lines of 6 meters long. We used a cultivating transgenic GB874. Were evaluated as characteristics Insertion First pod; Number of pod FOR grains; percentage of pods with one, two, three Four Grain OR, percentage of abortive pods; plant height; booth; Productivity; mass of one hundred grains; Two plants dry mass and number of pods per plant. On the basis of results obtained DONE UP que an Application Potassium doses not soy cultivation NOT interfere with the development and productivity of culture, possibly because the Liberation of K of maize straw was grown que earlier.
