Produção de alface em diferentes coberturas de solo

Abstract

The objective of this work was to evaluate the response of different soil coverings on the growth and production of lettuces. The experiment was conducted from September to December 2022, on a private property located on BR 472 - Km 2, located in the municipality of Santa Rosa, RS. The experimental design was completely randomized, in a bifactorial scheme (3 x 2) with factor 01 - soil cover types (soil with black oats, black mulching and no cover) and factor 2 - lettuce cultivars (curly and American). each treatment consisted of 4 repetitions. The height of the plants (cm), the total transverse diameter of the plant (cm) (bottom leaves + head) were evaluated weekly. After the harvest, commercial fresh mass (Kg) and dry mass (Kg) were evaluated. For the plant height variable, the use of dry oat cover provided better plant development. Based on the data obtained, it was concluded that no covering method (no covering, black oats and mulching) promoted a better productive performance in the different varieties of lettuce (curly lettuce BS 55 and iceberg lettuce Lucy Brown).
