An updated version of the Sorghum Growth and Development poster has been published by K-State Research and Extension. The full-color poster is 20x30 inches, and describes nine stages of growth of the sorghum plant. New features include key management practices associated with each growth stage, updated graphics, and the dry-down progression of the grain until physiological maturity.
Producers should pay close attention to the growth stage of their wheat before making spring herbicide applications. Some herbicides must be applied after tillering, several must be applied before jointing, and others can be applied through boot stage. The earliest practical and labelled applications generally result in the best weed control.
Winter wheat is beginning to break dormancy, and the Kansas Mesonet has a tool to help track crop development. This tool provides the propability of first hollow stem occurrence for wheat varieties in Kansas. This is important for dual-purpose wheat growers because it is the optimal time for grazing termination to maximize forage yield while minimizing grain yield losses.
