Adubação da batatinha resultados preliminares referentes ao emprêgo parcelado do N e K

Abstract: RESUMOProcurando estudar a influência da aplicação parcelada de nitrogênio e potássio, sôbre o desenvolvimento e produção de tubérculos de batatinha, foi organizado um plano preliminar com a duração de três anos, executado em Campinas, em solo pertencente ao grande tipo Glacial. Nêsse plano foram subdivididas as doses de nitrogênio e potássio, provenientes respectivamente do salitre do Chile e cloreto, de maneira a têrmos a aplicação de uma só vez (no ato do plantio), em duas, três e quatro vezes.Os resultados… Show more

“…On the other hand, researchers such as Vieira and Sugitomo (2002) found higher yields in areas where nitrogen and potassium were divided into two applications (planting and hilling), in comparison to the area where the N and K were supplied in a single application, along with the phosphorus in the furrow at planting. Boock and Catani (1956) observed an increase in the productivity of potato, mainly in years with high rainfall when they did the parceling of nitrogen and potassium fertilization, subdividing the nutrients three times. In the study developed by Mallmann (2001) in which were evaluated doses of N, P and K and split applications of N (80 kg ha -1 of N at sowing + 40 kg ha -1 of N 30 days after planting) and (80 kg ha -1 of N at sowing + 80 kg ha -1 of N 30 days after planting) cv.…”
