Companion crop, herbicide and weed effects on establishment and yields of alfalfa-bromegrass mixture
Bird damage, from sowing to crop establishment, is an important issue for farmers in many parts of the world. However, reliable and cost-effective solutions remain elusive because management tools research on subject are limited. The spatial variability damage across landscapes adaptative behaviour birds create further challenges. Additionally, must be tackled at landscape scale involve a varie...
Elderberry is an alternative crop that holds promise for further commercial development in Florida. This 7-page fact sheet written by Kevin Athearn, David Jarnagin, Ali Sarkhosh, Juanita Popenoe, and Steven Sargent published the UF/IFAS Food Resource Economics Department reviews information on markets elderberries elderflowers estimates establishment costs potential returns a 3-acre elderberry ...
BACKGROUND AND AIMS Early flooding helps control weeds but reduces seedling establishment in direct-seeded rice (Oryza sativa). When combined with appropriate management practices, the use of genotypes that better tolerate flooding during emergence can enhance crop establishment in flood-prone areas. Management options include seed pre-treatment and we tested the influence of pre-soaking for 24...
Numerous studies have addressed effects of rising atmospheric CO2 concentration on rice biomass production and yield but effects on crop water use are less well understood. Irrigated rice evapotranspiration (ET) is composed of floodwater evaporation and canopy transpiration. Crop coefficient Kc (ET over potential ET, or ETo) is crop specific according to FAO, but may decrease as CO2 concentrati...
Soil compaction can affect crop growth and greenhouse gas emission and information is required of how both these aspects are affected by compaction intensity and weather. In this paper we describe treatments of compaction intensity and their effects on soil physical conditions and crop growth in loam to sandy loam cambisol soils. Soil conditions and crop performance were measured over three sea...
Research made possible through the use of the wealth of genomic information and genetic resources available for model plant species such as Arabidopsis thaliana has led to a substantial increase in our knowledge about how plants respond to stressful environmental conditions. This leap in understanding provides the basis for many new strategies for optimization of stress tolerance in crop plants...
