Yield Determination in Major Small Grain Crops in Response to Nitrogen Fertilization.

ABSTRACT: Small grain crops showed significant yield variation under different nitrogen fertilization treatments. Understanding factors influencing yield is crucial for optimizing productivity. This study assessed how nitrogen fertilization affects grain number, grain weight, and other yield components in triticale, wheat, six-rowed, and two-rowed barley across multiple locations and seasons. Key traits, including grain number per spike, spike number per unit area, and spike dry weight, were analyzed. Triticale cultivars achieved the highest average grain yield (GY) of 8709 kg ha-1, significantly outperforming wheat (7656 kg ha-1) and six-rowed barley (7676 kg ha-1), particularly under high nitrogen (100 kg N) fertilization, where triticale reached 9184 kg ha-1. Grain number per unit area (GN) was s
