Abstract
Aims: This work was developed with the aim to evaluate the development of irrigated peanut with salt water and application of vegetable ash doses.
Study Design: The experiment installed was in a completely randomized design, in a 5x4 factorial scheme, with five replicates.
Place and Duration of Study: The experiment was conducted between January and April 2015, in a greenhouse of the Federal University of Paraíba, in Bananeiras, PB, Brazil.
Methodology: Peanut seeds cultivar BR-1 was planted in pots (5 dm3). Irrigation with different electrical conductivities of irrigation water (0.5, 1.5, 2.5, 3.5 and 4.5 dS m-1) was used 20 days after emergence until the end of the cultivation and the four doses of vegetable ash (0.0 1.5, 2.5 and 3.5 g kg-1 soil) were applied at the beginning of the crop. Were evaluated: plant height, leaf area index, root length, number of pods, number of branches, number of seeds, root dry matter, shoot, pods and seeds and total chlorophyll.
Results: The use of saline water influenced all variables analyzed in peanut regardless of the use of vegetal ash.
Conclusion: The use of vegetable ash was not efficient as an attenuating agent of the deleterious effect of irrigation water salinity on peanut.
