Cultivo de alface e coentro em sistema consorciado e solteiro

Abstract

The cultivation of vegetables is an intensive activity, with constant use of the soil, investment by high area and attractive economic return. In the current scenario, in which agriculture with a lower environmental impact is sought, intercropping cultivation, by optimizing the use of inputs, contributes to Olericultura, highly demanding of natural resources and agricultural inputs, being practiced in a more sustainable way. Given this, the objective of this work was to evaluate the agronomic performance of lettuce and coriander crops in single and intercropped cultivation in the municipality of Uruçuí PI. The experimental design used was a randomized block, with three treatments and four repetitions, with the treatments represented by single cultivations of coriander (cv. Verdão) and lettuce (cv. Palmas, curly group) and intercropped coriander-lettuce cultivation. The consortium was established in the form of alternating lines of the corresponding cultures. The following biometric parameters for lettuce culture were evaluated: fresh plant weight (g), commercial fresh weight (g), leaf fresh weight (g), number of leaves per plant (g), leaf dry mass and yield total per m2 (kg). And for the coriander crop, the fresh weight of the aerial part, fresh weight per m2, productivity, fresh weight of the roots were evaluated. Based on the fresh weight of the plants, the number of bunches / m2 was calculated, considering the individual mass of 100 g. The results showed that there was no significant difference between single and intercropping for lettuce. However, the intercropped coriander showed higher fresh weight of the aerial part, productivity (kg.m-2) and number of sauces, to the detriment of monoculture. In addition, the intercropping of lettuce-coriander was feasible under the conditions of this experiment, since the Area Equivalence Index (IEA) was 2.1.
