Small-scale and family-oriented organic growers must be continually innovative and efficient in their operations in order to remain in business. One strategy for small and organic farmers is development of niche markets and specialty or high-value alternative crops, such as medicinal herbs. The American Southwest has a large number of native medicinal herb species that have been used traditionally by indigenous and Hispanic cultures. By and large, these species have been wild-harvested from native stands, mostly for personal, family, or local use.
Organic fruit production in the US, especially the western regions, is expanding. The increase is occurring for both economic and ecological reasons. Current market conditions dictate that organic apple growers produce large, flavorful, high quality fruit. Large, high quality fruit receive price premiums and market acceptance whereas small fruit can be difficult to sell, even at lower prices. To grow large fruit, trees must be unstressed and provided with adequate water and nutrition. Weeds can compete with fruit trees for both water and nutrients.
This project examined whether targeted mowing of winter rye cover crop (Secale cereale L.) would increase its weed suppression ability by increasing levels of rye’s major allelochemicals, Hydroaxamic acids (Hx), and subsequently increase crop yield in an organic tomato production system. The project was conducted on organic farms in Upper Marlboro (2003), and Beltsville (2004), Maryland, using a rye cover crop that was grown as a monoculture and as a mixture with crimson clover, and black mulch.
1. To investigate the abilities of six in–row weeding implements to control in-row weeds in organic soybeans and corn. The initial selected six implements were reduced to five after preliminary trials showed that the Bezzerides Cultivator System with spyder set and spring hoe, was similar with the Bezzerides Cultivator System with spyder set and torsion weeders. This change was made with the agreement of the farmer. Also it was decided to use the Williams tool system as the tine weeder without the optional side knives offered.
The original objectives of this project as stated in the proposal were to: 1) Test the effectiveness of high glucosinolate-containing meals at controlling soilborne diseases (damping-off and white mold of lettuce) in an organic farming system. 2) Determine the influence of these materials on N cycling processes in organic systems.
The overall goals of this project are to (1) optimize potato yield without using chemical herbicides or fertilizers, and (2) disseminate the knowledge and results generated from this study to farmers and agricultural professionals throughout the United States.
(1) To determine the effect of cover crop seeding rate and planting arrangement on cover crop biomass production, cover crop canopy development, and weed suppression. Seeding rates included a standard rate (1x) typical on farms in the area, and higher rates (2x, 3x). Plant arrangements included a one-way versus a grid drilling pattern. This was the objective of trials 1 to 3.
Project objectives were:
a) To determine which weed reduction system is the most economically effective by:
1) Determining total labor and material cost for each weed control system.
2) Determining effectiveness of each weed control system by recording percent weed species emergence and percent weed cover throughout the year.
3) Determining total garlic yield for each weeding system.
4) Determining garlic quality, as measured by bulb size, for each weeding system.
The objective of the study was to evaluate and document the efficacy and potential of a kaolinbased particle film coating in suppressing plum curculio, codling moth, red-banded leafroller, oriental fruit moth, and certain bacterial and fungal pathogens in apples, while fine tuning application recommendations for Midwestern growers.
Objectives were: 1. to provide beekeepers with safe, effective, reliable and affordable alternatives to Apistan and Coumaphos for control of parasitic mites. Currently, these chemicals must be applied twice each year to ensure colony survival, and that is often insufficient. I will investigate alternative strategies that either reduce the use of synthetic pesticides by ½ or that eliminate them all together.
