Biochar e salinidade da água de irrigação no crescimento e produção de rabanete

Abstract

Salinity imposes difficulties for the implementation of any crop, hence the importance of research in this area, aiming to find ways to facilitate production. Biochar, is the name given to a type of charcoal, which correctly applied to the soil can serve as a corrective, is obtained by the pyrolysis process. According to what was presented, the work aimed to evaluate the influence of biochar on radish culture, according to the harmful effects of salinity. The treatments were done as follows (soil layer 0 – 20 cm; biochar + soil) the bags had a capacity of 2 kg and 3% of the bags' capacity were biochar, completing the rest with soil. The design used was completely randomized in a 5 x 2 factorial scheme, with four replications per treatment, totaling 40 units, being the treatments: 5 salinity levels (0.5 (control); 1.5; 2.5; 3, 5 and 4.5 dS m-1). At the end of the crop cycle, the radish plants of the saxa variety were collected and analyzed regarding the number of leaves (NF), leaf area (AF - cm2), plant height (AP - cm2), shoot dry mass ( MSPA - g), root mass (MR - g) and bulb mass (MB - g). After the nalysis, it was concluded that the biochar does not interfere with the harmful effects of salinity. The data obtained will be subjected to analysis of variance by the F test, and the means compared by the Tukey test of Regression.
