Green soybeans: Physical and rheological properties, optimization of harvest time, and mechanical harvesting and shelling
"Physical and rheological properties of green soybeans were measured at different stages of seed development. These properties included texture, color, size, and seed strength. Mathematical models were developed relating each property to seed development. The models were then combined to develop an …

Effect of Harvest Time on the Incidence of Red Drupelet Reversion and Development of Tetraploid Linkage Maps in Blackberry
… of a fully black berry begin to turn red after harvest. A two-year study was done at the UA System to discover if harvesting at different times of day and/or harvesting genotypes with different levels of firmness might influence the incidence of RDR in blackberries after one week of cold storage …

Bioactive compounds in leek (Allium ampeloprasum var. porrum): analysis as a function of the genetic diversity, harvest time and processing techniques
… a range of leek cultivars and as a function of harvest time. On the other hand, the behaviour of these compounds was investigated during different processing/stabilisation techniques. Although leek is a popular vegetable in many European countries, the limited scientific knowledge concerning its …

The Relationship Between Mineral Nutrition and Late-Season Bunch Stem Necrosis of Cabernet Sauvignon (Vitis vinifera L.) Grapevines
… and calcium produced little change in bloom-time petiole mineral concentration. Fertilizer treatments appeared to have no effect on BSN incidence, but the incidence of BSN was less than or equal 1% in the control plots each year. During the 1996 season at Winchester vineyard, bloom-time leaf …

Productivity, physiology, community dynamics, and ecological impacts of a grassland agro-ecosystem: integrating field studies and ecosystem modeling
… first part of my research addresses the optimal harvesting time of prairie biomass to achieve the maximum yield within one production cycle. Due to the biomass quantity-quality trade-off, the balance among yield, biomass quality, and impacts on environment needs to be carefully considered when …

Industrial hemp agronomic management for grain, fiber, and forage
… of tillage on seed and fiber production, optimal harvest time for seed yield and quality, the response of seed yield to nitrogen fertility rates, and the potential of hemp as a forage crop. A three-year study was conducted in Blacksburg and Orange of Virginia State to assess the effects of tillage …
