Produção agroeconômica de mandioquinha-salsa e cravo-de-defunto em cultivos solteiro e consorciado

Abstract

The aim of this work was to evaluate the agro-economic yield of "Amarela de Carandaí" Peruvian carrot and marigold as a function of cultivation system and number of rows per plot in environment conditions of Dourados-MS. Peruvian carrot (M) and marigold (C) with two (M2 and C2) and three (M3 and C3) rows under monocrop and intercropping system (M2C3 and M3C2) were studied. Harvest of capitula of marigold was started from 30 days after transplant-DAT, weeky, were done filteen consecutive harvest. The harvest final of plants was on 139 days after transplant-DAT. Harvest of Peruvian carrot was done on 231 days after planting-DAP, when plants showed more than 50% of senescence of foliar area. Peruvian carrot didn‟t produced commercial roots. The highest yields of fresh and dry weight of crowns (2.35 and 0.40 t ha-1) and of shoots (1.78 and 0.27 t ha-1) were obtained with monocrop system and under three rows of plants per plot. The highest number of shoots was obtained under three rows of plants per plot arrangement (366.30 thousand ha-1) and the highest number of roots was under three rows (361.35 thousand ha-1). Fresh weight of capitula of marigold was not influenced by intercropping system neither by plant arrangement, with an average of 12.37 t ha-1. Considering that the net incomes were negative, intercropping should not be recommended to the producers of Peruvian carrot and/or marigold.
