Barley silage harvested at boot and soft dough stages for lactating cows
Barley (Hordeum vulgare, L.) harvested at boot (5/7/88) and soft dough (6/6/88) stages of maturity was ensiled for nutritive comparisons. Boot stage was wilted and soft dough was direct cut at 15 (SD-Lo) and 25 cm (SD-Hi) above ground. Yields (kg DM/ha) were 3690, 8750 and 6287 for boot, SD-Lo and …

Evaluation of alternative forage species to reduce risk for cow-calf production systems in the Appalachian region
… May through October of 2009 and 2010 at the late boot stage at a cutting height of 10cm. Subsamples were analyzed for dry matter and nutritive value. To assess risk, bootstrap distributions of biomass and quality data were generated by Monte Carlo simulation and compared against an objective …

Yield and water use efficiency of different plant populations of dryland corn and sorghum
… planting. This stress occurred just prior to the boot stage for sorghum at 60 to 68 days after planting. Crop water use, averaged over all treatments, was 494 mm for corn and 424 mm for sorghum. For corn, plant population did not influence grain yield and crop water use. Water use efficiency …

Effects of Maturity at Harvest of Triticale and Dietary Forage Inclusion on Production Performance, Nutrient Utilization, and Milk Fatty Acid Profile of Lactating Dairy Cows
… consuming triticale harvested and ensiled at the boot stage of maturity (BS), as compared to consuming triticale harvested and ensiled at the soft-dough stage of maturity (SDS), and that the difference would be greater in high-forage diets. A single field of triticale was planted, and harvested at …
