Abstract

Peanut (Arachis hypogaea) is one of the most cultivated oil plant worldwide since it is widely consumed as food. In this sense, this work aims to evaluate the growth, production and tolerance of peanuts under the effect of different levels of electrical conductivities in irrigation water and bovine biofertilizer. The experiment was conducted in a greenhouse located at the State University of Paraíba - Campus IV, municipality of Catolé do Rocha, Paraíba, Brazil. The experimental design was completely randomized with a factorial arrangement of 4 x 2, with six repetitions. There are two treatments: the first consisted of the combination of the electrical conductivity (ECw) of 0.5; 1.5; 3.0 and 4.5 dS m-1 in irrigation water and the second is the application of bovine biofertilizer (with and without). Absolute growth rates and relative plant height, stem diameter and leaf area, number of pods per plant, 100 seed weight, number of seeds per plant, seed weight, seed mass + grains, root dry mass, shoot and total and tolerance index were assessed. From the results obtained, it can be concluded that the electrical conductivity of the irrigation water from 0.5 dS m-1 significantly reduced the growth and production of A. hypogaea, however the application of bovine biofertilizer increased the results obtained.
