Open flame torches shown to be cost-effective, non-fatal to crops

Researchers evaluated damage and recovery responses of four cranberry varieties to handheld propane flame cultivation torches used for spot weed control. They found that the flame cultivation technique caused less damage to cranberry plants than incidental exposure to glyphosate during spot treatment of weeds. The results indicated that flame cultivation could be successfully integrated into weed control for cranberry crops in certain situations, including organic farming.

Study of consumer preferences finds fragrance is key

The IdeaMap® software suite and the concept of Mind Genomics® were applied to analyze which features of flower products influence consumer perception. Researchers created a database to define how individuals perceive distinct components of an overall flower product. Results showed that the highest and lowest interest values were for elements in the "flower fragrance" category, indicating that fragrance is important with respect to consumer satisfaction.

Soil quality "not adversely affected" in study of convention and organic vegetable production

A study compared soil under high tunnels with soil in adjacent fields over 8 years. The data showed elevated soil salinity under high tunnels, particularly with the organic management system, but the increase was not enough to be detrimental, even to sensitive crops. The researchers determined that overall soil quality was not adversely affected in the experiments with conventionally or organically produced vegetable crops.

'NuMex Cinco de Mayo', 'NuMex Thanksgiving' most tolerant in experiments with saline irrigation water

Horticulturists studied the relative salt tolerance of 10 cultivars of ornamental chile peppers by irrigating mature plants with saline solutions and germinating seeds in saline substrate in a greenhouse. Experiments showed that 'NuMex Cinco de Mayo' and 'NuMex Thanksgiving' were the most tolerant of the cultivars in study, while 'NuMex Christmas' and 'NuMex Memorial Day' were the least salt-tolerant varieties. The eight other varieties tested were determined to be moderately salt tolerant.
