Effect of Gypsum Applications on Organic Crop Production and Postharvest Quality

چکیده
Introduction With a 20% growth rate in 2001, organic agriculture continues to expand in the U.S. and the world (OTA, 2002). After the release of consistent federal standards for products marketed as “organic” in October 2002 (USDA/AMS, 2002), organic production and consumption was expected to increase beyond current organic sales of $10 billion in 2001 (OTA, 2002). In 1999, Iowa farmers reported 150,000 acres of organic production to the Iowa Department of Agriculture and Land Stewardship survey (IDALS, 2000a), although statistics for organic horticultural crops remain underreported.

Effect of different fruit position on postharvest quality of F1 hybrid redfleshed watermelon Hi-U 16 was examined. In this study only one main vine was trained and maintained. The plants were allowed to set three fruits naturally at the first (8th - 11th nodes), second (13th - 16th nodes) and third (18th - 21th nodes) position. Fruits were harvested at 35 days after anthesis. Fruit weight, diam...

The effects of postharvest oxalic acid (OA) treatment on ethylene production, fruit quality, bioactive compounds and antioxidant activity of peach fruit, were examined. Fruits were treated with oxalic acid immediately after harvest and stored at 1° C and 90% relative humidity for 28 days. The oxalic acid treated peach fruit exhibited significantly lower levels of ethylene production, pH, total ...

Consistent use of high RSC water may deteriorate the physical properties of soil and increases pH and SAR of soil. Continuous use may reduce germination / the establishment of seedling, retards plant growth and leads to a significant reduction in yield. Therefore, a field experiment in microplots was displayed at research plot in St. John’s College, Agra to study the effect of sodic water on th...

متن کاملCrops for Certified Organic Pepper Production
Introduction Organic production rose to 2.3 million acres in the U.S. in 2001 (USDA-ERS, 2002). Much of the increase has been associated with the implementation of consistent federal standards for products marketed as “organic” in October 2002 (USDA/AMS, 2002). In order to meet certified organic requirements in the state of Iowa (IDALS, 2000), a soilbuilding cover crop is required for at least ...
