Item Rejeito industrial de cana-de-açúcar para produção e análise de sementes de cultivares de amendoim(2019-02-11) Almeida, Guilherme Tenório de; Viana, Jeandson Silva; http://lattes.cnpq.br/2151004858957292; http://lattes.cnpq.br/9331761640004208Peanut (Arachis hypogaea L.) is a plant native to South America, including Central Brazil. With considerable production in the Northeast in the states of Bahia, Paraíba, Sergipe and Ceará, reaching in the harvest of 2018 a total of approximately 2.3 tons per hectare. In order to reach high yields in the peanut crop, it is essential that there is an expressive supply of nutrients and for this, this work was developed to identify a cultivar and the source of fertilization that contributes most to crop productivity and seed quality. The study was conducted in pots with a volume of 8.5 liters, under field conditions, in a 2 x 6 factorial scheme (two cultivars x six treatments), and five replications, totaling 60 plots. The treatments were designed according to the recommended dose based on Potassium, from 0 to 150% of the dose and the addition of an additional control with traditional NPK fertilization. Variables of the plant part and the seeds harvested from the experiment were analyzed, comparing the presented differences between the cultivars and the different treatments. The cultivar Caiana obtained the highest estimate of production when using the dose of 100% of sugarcane residue followed by the Absolute Witness, presenting an estimate of 1611.69 and 1416.80 kg / ha respectively. The cultivar Tatu obtained similar results, however in different treatments. The treatments that resulted in better production estimates were those with 50% sugarcane residue per hectare and NPK fertilization, with an estimate of 1666.78 and 1535.25 kg / ha. The absolute control was the lowest value, only 418 kg / ha. The cultivar Caiana has the highest green mass and quality of its seeds superior to cultivar Tatu ST. The ash from sugarcane bagasse constitutes a good source of nutrients, however, it is recommended to repeat the experiment under other conditions to confirm its potential as fertilizer. The soil used in the experiment is of good fertility.
