AGRONOMIC PROPERTIES OF SOYBEAN CROP MANAGED WITH MINERAL AND ORGANOMINERAL FERTILIZERS

Abstract

In its composition, the organomineral fertilizer has an organic fraction from industrial waste or agricultural activities, such as waste from poultry or pig farming. The present work aims to evaluate the agronomic properties of soybean crop managed with mineral and organomineral fertilizers. The experiment was implemented at the Agro Latina BR Experimental Station, located in the municipality of Guatambu/SC, in the 23/24 soybean harvest. The experimental design was the Randomized Block Design with 7 treatments and 4 replications, totaling 28 plots. The response variables evaluated were: Root volume and length at 5, 10, 20 and 30 days after emergence (DAE); Nodulation in V3 and R1; NDVI and SPAD in V3 and R1; Contents of macronutrients, micronutrients and enzymatic activity of the soil in pre-sowing and R1 via leaf analysis; Number of pods per plant, number of grains per pod, weight of 1000 grains and yield (kg/ha). Under the conditions in which the experiment was conducted, the results obtained allow us to conclude that: the dose of +25% Organomineral (05 15 15) differs provides the best results in relation to the qualitative (volume and root length; number of active nodules and SPAD reading) and quantitative (number of pods per plant; weight of one thousand grains and yield) response variables.
