Late-Season Nitrogen Fertilizer Application in Soybean

Nitrogen Fertilizer Effects on Soybean Growth, Yield, and Seed Composition

While previous research has been contradictory, potential grain yield responses and seed protein increases have led to con­ tinuing interest in N fertilizer application to soybean (Glycine max (L.) Merr.]. Field experiments were conducted at seven lo­ cations from 1990 to 1991 in Alabama to determine soybean response to N fertilization at various growth stages. Treatments included a factorial a...

Does nitrogen fertilizer application rate to corn affect nitrous oxide emissions from the rotated soybean crop?

Little information exists on the potential for N fertilizer application to corn ( L.) to affect NO emissions during subsequent unfertilized crops in a rotation. To determine if N fertilizer application to corn affects NO emissions during subsequent crops in rotation, we measured NO emissions for 3 yr (2011-2013) in an Iowa, corn-soybean [ (L.) Merr.] rotation with three N fertilizer rates appli...

Aqueous And Gaseous Nitrogen Losses Induced By Fertilizer Application

Evaluation of Tillage, Nitrogen Fertilizer and Crop Residue Management on some Agronomic Traits of Soybean

This study setout to investigate the effect of wheat residue, tillage, and nitrogen fertilizer management on some agronomic traits of soybean as a split split plot based on randomized complete block design with three replications. The main plots included wheat residue management: collecting and leaving residue and sub plot included tillage (without tillage and conventional tillage), and the sub...
