Produção de amendoim consorciado com palma forrageira no agreste meridional pernambucano

Abstract

The intercropping is an alternative to ensure the income of farmers and reduce agricultural losses, besides bringing benefits to crops with lower occurrence of diseases and pests, providing better utilization and enrichment agroecosystem. The study aimed to evaluate the effect of plant population on peanut inoculation and intercropping system with cactus on growth, biomass and productivity of groundnut and palm development after planting forage and crop residues incorporation of peanuts. The treatments consisted of different populations of peanuts (one, two and three rows of peanuts from a space of two meters of cactus), with and without inoculation, analyzed in split plot scheme (3 x 2), totaling six treatments in randomized block design with four replications. The variables evaluated were survival percentage initial and final plant height, number of branches, weight of shoot and root, number of nodules, nodule dry weight, number of pods per plant, total biomass and pods yield characteristics of peanut pods and height, length, width and thickness of the cactus pear after harvest peanuts. The largest population of plants in many lines of peanut intercropped with cactus promotes greater total biomass and productivity and does not change the height, number of branch, shoot dry weight, and root nodules, number of pods with two, three four seed and leaf number. The inoculant application did not cause an increase in productivity, biomass and growth of peanuts. Inoculation peanut population associated with lower peanut provides greater uniformity in length with a grain leguminous, while the greatest width occurs when it is cultivated with two rows of peanut inoculant. Treatment with two lines inoculation provided greater uniformity in the length of pods with three seeds and widths of these pods were more influenced by three lines without inoculant. Pods with four grains present uniformity in length with the analysis classes of treatments with the highest population of peanuts. The intercropping with peanut cactus did not influence the height and length of cladodes of plants, but the greater thickness was observed in cladodes harvested forage cactus planted with two rows of peanuts.
