Productivity Efficiency Of Microbian Soil Conditioner And Vermicompost In Oryza Sativa (L)

Abstract

Fertilization is an irreplaceable practice in agricultural activity, consisting of replenishing the soil with nutrients that are depleted by the extraction of the crops themselves, which is one of the most valuable items in the structure of production costs in rice cultivation. It is therefore necessary to identify strategies that allow both the good development of the crop and the reduction of costs, and to use agrosostainable and environmentally friendly alternatives. The objective of this study was to evaluate the efficiency of the application of earthworm compost and a microbiological soil conditioner for 90 days. A completely randomized block experiment was carried out with 4 replicates and five treatments (Tto1: Control, Tto2: soil conditioner with 3L/ha; Tto3: soil conditioner with 4L/ha; Tto4: soil conditioner with 4L/ha and Tto5: soil conditioner with 4L/ha): vermicompost 200 kg/ha. The field evaluation was carried out in three time periods: 30, 60 and 90 days after the application of the respective treatments. The results show that the treatment where microbial soil conditioner was applied at a dose of 4 L/Ha presented the highest efficiency averages in the increase of productive parameters in rice cultivation. This is the first study to be carried out using a microbial soil conditioner.
