Corn salad (Valerianella olitoria L.) yield response to cell size of plug trays
The research was undertaken to determine if the plug tray cell size had an impact on plant characteristics and yield of corn salad (Valerianella olitoria L.). Seeds of four cultivars (‘Ljubljanski’, ‘Holandski’, ‘Flavor’ and ‘Masse’) were sown in styrofoam plug trays with 40 cells (60 ml cell), 84 cells (35 ml cell) and 160 cells (20 ml cell). Plants growth generally increased with cell size, t...
متن کاملMycorrhizal Inoculation of Tomato and Onion Transplants Improves Earliness
Field experiments were conducted near Weslaco, Texas (Lat. 26° 8' N) between 1999 and 2001 to evaluate the field performance of preand post-mycorrhizal inoculations of tomato and onion (2001 only) transplants. In 1999 ‘Heatmaster’ tomato (Lycopersicon esculentum Mill.) transplants were inoculated with Glomes intraradices (Reforestation Technologies, Salinas, CA) at transplanting; in 2000 ‘Heatm...
متن کاملImproved High Performance Trays
From a design and hydraulic standpoint, trays are relatively complex distillation internals. In the ongoing search for higher performance trays, one first must understand the hydraulic and mass transfer aspects of the tray operation such as entrainment, downcomer flooding, and vapor liquid contact. When this is well understood, then various aspects of the deck and/or downcomer designs can more ...
متن کاملeffect of k and n concentrations in nutrient solution on growth and quality of tomato transplants
the aim of this study was to evaluate the effect of different potassium (k) and nitrogen (n) concentrations in nutrient solution and their interaction on growth and quality of tomato transplants. a full factorial experimental design was carried out with three potassium concentrations (1.5, 3 and 6 meql-1) and three nitrogen concentrations (1.5, 3 and 6 meql-1) for 27 days after seed germination...
متن کاملNew Highspeed Mass-transfer Trays
The mass-transfer trays HighspeedTray, HighFlexiTray and SieveTray belong to a new generation of mass transfer trays that enable increase the capacity-efficiency profile and the flexibility of tray columns significantly. This increase is achieved by a special vapor and liquid distribution and contact systems installed on these trays and a combination of two different tray designs. These trays c...
