Beet Performance Under Different Irrigation Depths and Rock Powder Doses Added to Soil

Abstract

In the Upper Vale of Itajaí, Beet is largely employed mainly in small farms as an alternative to income generation. It is believed that in many properties the irrigation occurs without the control of the water blade applied to the crop, directly affecting the cost, provid- ing possible impairment with excesses or lack of water. In the region is widely used the use of rock dust, originating from slate with few researches carried out so far. The research conducted aimed to analyze the effect of different irrigation depths applied daily in the beet crop with doses of slate powder added to the soil. Twelve treatments were performed, being 3 daily irrigation slides, with 2 slides being calculated from the Hargreaves and Samdani equation and a 3 mm fixed blade with 4 doses of rock dust. The cultivation was carried out in the greenhouse of IFC Rio do Sul. The harvest was carried out 66 days after transplantation, and several morpho- logical and qualitative data of the plants were evaluated. Analyzing the parameters it can be affirmed that the best irrigation blade was the corresponding to 130% of the crop evapotranspiration. In relation to rock dust, no significant correspondence was found for the development of the parameters considered.
