A study investigated the relationship between parental attitudes toward nature and their child's outdoor recreation and how these attitudes related to their child's health problems. Relationships between time spent indoors on video games or watching television and health problems in children were identified. Time spent outdoors in free play was inversely related to reports of health problems in children.

Scientists learn more about bacterial wilt that devastates crops on Virginia’s eastern shore

Four trials were conducted on the Eastern Shore of Virginia to determine the temporal and spatial distribution of bacterial wilt throughout commercial tomato fields. The researchers found that as bacterial wilt incidence increased, either by contact between roots of adjacent tomato plants or movement of the pathogen in surface irrigation water, symptomatic plants become more clustered within rows. The study recommended reducing irrigation frequency as a possible answer to limiting incidence of the disease.

Study includes recommendations for growing promising biofuel crop

Researchers evaluated greenhouse techniques for the production of jatropha (Jatropha curcas). Seedlings were transplanted into 1-gallon containers filled with bark mix, coir, or peat-based substrate and fertilized using four different application rates of controlled-release fertilizer. Plants were watered every 2, 3, or 4 days for 80 days. The study recommends growing jatropha in containers filled with peat substrate, fertilizing plants with 5.9 oz/ft3 of controlled-release fertilizer, and irrigating every 2 days as a best practice.

Biocontainers Hold Their Own in Tests with Plastic Pots

E-mail Print

Alternative containers found effective for bedding plant production, landscape applications

Biodegradable and plastic containers were evaluated for greenhouse and landscape production of 'Score Red' geranium, 'Grape Cooler' vinca, or 'Dazzler Lilac Splash' impatiens. Plants grown in all tested containers produced marketable plants; results showed that plants grown in 5-inch plastic or paper containers generally performed better than those grown in other containers. The results indicated that direct plant biodegradable containers can provide landscapers with suitable alternatives to plastic or compostable containers.

Seasoned professionals say experience is still the best teacher for new grads

A study evaluated attitudes and perceptions of practicing landscape architects in the southeastern United States with regards to the importance of horticultural knowledge. While seasoned practitioners in the residential design market said they had a favorable opinion of their own plant knowledge, they felt that recent graduates in landscape architecture have insufficient knowledge of plants. The authors say the study shows a continued need for both formal and informal extended education classes for the profession.
