Produtividade do algodoeiro adensado em segunda safra em resposta à adubação nitrogenada e potássica

Abstract: Produtividade do algodoeiro adensado em segunda safra em resposta à adubação nitrogenada e potássica 1 O nitrogênio e o potássio são os nutrientes mais requeridos pelo algodoeiro. O algodão, cultivado em segunda safra, após a colheita da soja, tem sido uma opção dentro dos sistemas de produção do cerrado brasileiro. Este trabalho objetivou avaliar o efeito das adubações nitrogenada e potássica sobre o estado nutricional, os componentes de produção e a produtividade do algodoeiro, cultivado em sistema adensa… Show more

“…In the 2016/2017 season, Brazil produced 1.6 million tons of fiber and the Midwest region accounted for approximately 65% of the total Brazilian production (Conab, 2018). With the emergence of new varieties and the purpose of reducing crop costs, several have been carried out to implement reduced interrow spacings, called ultra-narrow row (0.19 to 0.38 m), narrow row (0.39 to 0.76 m), and conventional (<0.76 m) (Borin et al, 2017).…”

“…Yield had a quadratic response, with maximum value obtained when using 77.4% of liquid fertilizer. According to Borin et al (2017), increasing doses of Nitrogen have a significant effect on the leaf nutrient content and yield of the cotton crop. Figure 3.…”

“…When applied at adequate doses, this element stimulates growth and flowering, regularizes the plant cycle, increases yield, and improves fiber length and resistance. At high doses, N increases the plant vegetative development to the detriment of production and late formation of cotton bolls (PILBEAM, 2011;BORIN et al, 2017;KHAN et al, 2017).…”

“…Plant spacing and density have been proposed for the growth of different plants; in the case of cotton, it has sought to meet specific needs regarding cultural practices, increasing yield, and decreasing production cost (BORIN et al, 2017). Several studies have addressed the decrease of space between planting rows and increase of number of plants per area.…”
