Spring irrigation of tall fescue for seed production
Tuesday, March 12th, 2013Here’s a new article on spring irrigation of tall fescue seed crops published in Field Crops Research. This work was led by Krista Huettig, a former graduate student and member of my research team. The study reports several important findings and was the first study to demonstrate that spring irrigation increases seed yield in tall [...]
Perennial Ryegrass Seed Price Trends
Thursday, March 7th, 2013Thomas G. Chastain Market conditions as well as the cost of production affect the profitability of grass seed production enterprises. Supply and demand dictate the price of seed. Since seed is an international commodity, the production conditions and seed yields in all regions around the world are important factors affecting seed supply. The size of [...]
Honor for Temperature and CO2 effects on seed quality article
Saturday, February 9th, 2013An international team of scientists led by Dr. John Hampton of New Zealand is developing a series of articles on the effects of elevated temperature and CO2 on seed quality and seed production. I’m a member of this team and the first installment of our series was published last year in the Journal of Agricultural [...]
