Response to Late Foliar Nitrogen Application in Soybean Productivity
Journal Title: Journal of Experimental Agriculture International - Year 2017, Vol 15, Issue 1
Abstract
To achieve high productivity in soybeans, a balanced fertilization and careful management is necessary during the period in which the plant requires larger amounts of nitrogen is essential. This study evaluated the effect of foliar nitrogen fertilization using ammonium sulfate at early grain filling stage of soybean crop. The experiment was performed during 2015/2016 crop in the state of Piauí, Brazil. Nitrogen was applied at doses of, 3, 6, 9, 12, and 15 kg ha-1 in a randomized block design with four replications. Data was recorded for number and length of pods, thousand seed weight and yield. Late foliar application of nitrogen showed no significant difference in grain yield of soybean plant.
