Yields and Soil Quality under Transitional Organic High Tunnel Tomatoes

Long term high tunnel production: Grafting tomatoes

My farm consists of 225 acres on hilly land in Lancaster County, PA. We grow a diversity of crops and our early tomatoes are grown in two acres of multi-bay high tunnels. I reluctantly was forced to fumigate in the tunnels due to problems with verticillium wilt (race 2). At my farm, we have looked at grafting to manage verticillium and other soilborne diseases in our tunnels, and have seen that...

Impactof Integrated Organic Nutrient Handlingon Fruit Yields and Quality of Strawberry cv. Kurdistan in Iran

This study was conducted during 2008-2009 to investigate the influence of different organic nutrient combinations on yields and quality of strawberry cv. Kurdistan in Iran. The experiment comprised of five organic nutrient treatment combinations including the recommended dose of N, P and K through chemical fertilizer as control. Treatment N2 (manure+Azotobacter+ woodash+phosphorus solubilizing ...

Effect of synthetic and organic soil fertility amendments on southern blight, soil microbial communities, and yield of processing tomatoes.

ABSTRACT Soil fertility amendments, including composted cotton-gin trash, swine manure, a rye-vetch green manure, or synthetic fertilizers, were applied to subplots and tillage on bare soil; or tillage followed by surface mulch with wheat straw were applied to main plots to determine the effect on the incidence of southern blight caused by Sclerotium rolfsii, yield of processing tomato, and soi...

Assessing Soil Quality in Organic Agriculture

Qualitative and nutritional differences in processing tomatoes grown under commercial organic and conventional production systems.

Organically grown products experienced a doubling in percent penetration of organic sales into retail markets during the period from 1997 to 2003; however, there is still a debate over the perceived quality advantage of organically grown fruits and vegetables. In a study focusing on commercial production of processing tomatoes, samples were analyzed from 4 growers with matched organic and conve...
