Nitrogen Rates and Side-Dressing Timing on Sweet Corn Seed Production and Physiological Potential

Abstract: Sweet corn is an important crop because of its seeds with high total sugar and low starch contents. As common corn, this group requires an adequate amount of nitrogen to reach high yields. However, the studies on nitrogen and sweet corn are performed for ear yield instead of seed yield. As seeds are the main propagation method for this species, we proposed to evaluate the effects of nitrogen rates as side-dressing at different plant stages of a sweet corn seed production. Sweet corn seeds (variety BR 400) were… Show more

“…Nitrogen (N) determines crop size and yield formation [5,6]. A side-dressing of 120 kg ha -1 nitrogen at V6 increased seed yield and kernel protein content [7]. In addition, phosphorus, potassium, and nitrogen can increase corn yields by promoting silking [8].…”

“…O nitrogênio é elemento critico na maximização da produtividade da cultura do milho doce (GAO et al, 2020;ZUCARELI et al, 2018). Embora existam inúmeros estudos com o milho comum, são limitados os estudos sobre o manejo do nitrogênio no milho doce (Saccharata group) (ZUCARELI et al, 2018).…”

“…O nitrogênio é elemento critico na maximização da produtividade da cultura do milho doce (GAO et al, 2020;ZUCARELI et al, 2018). Embora existam inúmeros estudos com o milho comum, são limitados os estudos sobre o manejo do nitrogênio no milho doce (Saccharata group) (ZUCARELI et al, 2018). Devido às pesquisas sobre a fertilização da cultura do milho doce serem escassas, o manejo do N, nessa cultura, ainda não foi padronizado, sendo as recomendações baseadas nas existentes para o milho comum (NAIK et al, 2019;CRUZ et al, 2015;ZUCARELI et al, 2018).…”
