Sobressemeadura de trevo vessiculoso em campo nativo, mediante correção de acidez do solo

Abstract

Currently, beef cattle farming is one of the main agricultural activities in the state of Rio Grande do Sul, the state stands out in the national scenario for still maintaining the productive system of beef cattle, based on the native field, reaching approximately 12 million hectares. However, this is seen as not very productive due to the fact that it produces low quantity and quality fodder in the coldest periods of the year, known as fodder void. Due to this, we tried to introduce a suitable species to produce fodder for the animals in those critical periods, the vesicular clover. The objective of this work was to evaluate the establishment and productivity of the overgrown vesicle clover in the native field, through soil acidity correction. The experiment was conducted in a farm whose activity is the production of beef cattle, in the municipality of Pirapó – RS, in a completely randomized design (DIC), with the following treatments: rooted native field + limestone + vesicular clover; and rooted native field + vesicular clover, in two different areas, middle hill and flat ground. All dealings in the plot were done manually. The experiment evaluation was performed by the direct method with area of 0.25cm 2 and the matter withdrawn was estimated through the greenhouse. In the flat ground area, the application of limestone along with vesicular clover presented superior results for forage production. While in the middle hill area the use of the soil corrective presented increment of productivity only for the first cut.
