Avaliação da biomassa de plantas de goiabeira cv. paluma tratadas com produtos biológicos em solos conducentes à meloidogyne spp

Abstract

The cultivation of guava (Psidium guajavaL.) is widespread throughout the world, [being a kind of reality with high economic and market potential, which, with this, still presents great possibilities of expansion around the world.]In Brazil, São Paulo and Pernambuco lead production, accounting for 36.3% and 31%, accounting for 67.3% of national production. However,diseases in guavain Brazil directly influence the productivityof this culture. Among the diseases, meloidoginose is one of the main causes of damage to guava producers. In this context, the work was evaluated as the aerial biomass problem and root portion of guava seedlings of cv. Paloma for two soil conditions leading to the three biological products. Soils were grown in areas of guiding guava in nematodes under two management, soil 1 with remnant characteristics and soil 2 in full culture, deposited in 10 L volume vessels that are projected with three products formulated with Bacilluspumilus, B. subtilis, B. amyloliquefaciens, Azospirillum sp., Pseudomonas sp., Rhizobium sp., Saccharomyces sp., B. licheniformis. With the end of the 90 days, with the measurement of the first planes, the fresh mass and the dry and dry mass, the diameter of the stem, pair of leaves, number of leaves and number of branches. The experiment was carried out without a randomized complete block design (DBC) with eighttreatments and four replications where the treatments, arranged in a factorial scheme 4 x 2. The results were those biological products tested in this experiment, not having as parameter the biomass differences in question relation to the two types of cultivated soils.
