Abstract

Soy is an oilseed of great economic importance in Paraguay. Foliar fertilization is a fundamental practice to meet the nutritional needs of the crop, therefore, the objective of this work is to evaluate the effect of the foliar application of cobalt (Co), molybdenum (Mo) and boron (B) with different doses and combinations in the soybean crop, the experiment was carried out in Curuguaty, the design used was randomized complete blocks with factorial arrangement of 9 treatments and 3 blocks, treatments were CoMo (0, 150 and 250 mL ha-1) and B (0, 500 and 1000 mL ha-1) applied via foliar during stage V8 of the crop. The following were evaluated: height of the plant, number of nodules, number of pods, yield and weight of 1,000 grains. For plant height, T7 had a greater height with 80.3 cm over 71.83 cm of the control, for the number of pods the T6 obtained a greater quantity with an average of 79.1 pods, while the Witness reached 64.4 pods per plant, the number of nodules in the interaction showed significant differences, being the T4 that presented greater amount, with 66.05 on 55.13 of the control, the yield of the crop showed increases with the application of the micronutrients, the best was the T4 with 2305 kg ha-1, compared to 1923 kg ha-1 of the control, and in weight of 1,000 grains there was a highly significant difference in the interaction, with T4 achieving 124.2 gr over 107.43 gr of the control; that is, the application of micronutrients such as cobalt, molybdenum and boron increases the yield of soybeans according to the result, so the application is recommended taking into account the cost benefit.
