Wheat Variety-Specific Grain Yield Response To Plant Density Under Intensive Management Conditions In Western Kansas, R. P. Lollato, K. Mark, B. R. Jaenisch

Kansas Agricultural Experiment Station Research Reports

Seeding rate determines the first yield component of field crops, which is the plant population. However, wheat is less responsive to plant populations than other crops due to the high plasticity in tillering potential, and this responsiveness depends on resource availability. The objective of this project was to evaluate winter wheat popu­lation, grain yield, and grain test weight responses to seeding rate and its interaction with variety in a highly managed production system where manageable stresses were limited. Experiments evaluating the response of the wheat varieties ‘Joe,’ ‘WB-Grain­field,’ ‘Langin,’ and ‘LCS Revere’ to seeding rates ranging from 200,000–1,000,000 seeds per …
