Non Technical Summary
Not all of greenhouse pepper, cucumber, and strawberry cultivars perform well under Louisiana conditions. Using soilless medium to grow these crops for one season is costly and can create a disposal problem. Also, runoff nutrient can create an environmental hazard. This project examines cultivar, substrate sterilization and repeated use, and runoff reduction on crop production.

Goals / Objectives
1. To evaluate greenhouse pepper, cucumber, and strawberry cultivars for production in different growing substrates and at various densities. 2. To examine the effect of substrate sterilization on production of these crops. 3. To develop economical irrigation and fertilization methods that optimize the root uptake of nutrients, yield, and limit or eliminate waste or runoff.
Project Methods
Objective 1: factorial experiments will be conducted during the spring and fall seasons to evaluate the performance of pepper, cucumber, and strawberry cultivars in different growing substrates. Plant density studies will include high, medium, and low densities. The interaction between plant density and yield will be determined. Objective 2: growing substrates will be sterilized using steam and or hot water for a period of one, two, and three minutes or left untreated. The effects of heat treatment on yield and disease incidence will be evaluated. Objective 3: individual plants grown in perlite or pine bark will be irrigated every hour with 125, 187.5, and 250 milliliters of water mixed with the recommended rates of nitrogen and potassium for a maximum of 12 hours a day.

Progress 01/01/00 to 12/31/04

Outputs
Studies on greenhouse seedless cucumber indicated that `Cumloude' was the highest yielding cultivar followed by `Bologna'. `Kalunga' and `Mariana' produced the least yield. All four cultivars produced long, straight, and dark green color fruit. None of the cultivars was resistant to powdery mildew disease. Studies on peppers indicated that `Cubico', a red fruited greenhouse cultivar produced an average of 3.5 kg per plant. Average production reached 7.1 kg per plant in Leamington area in Canada. Low production under our conditions was caused by high greenhouse temperature during the summer and early fall. Five strawberry cultivars were evaluated for yield and fruit size under greenhouse environment. Results indicated that yield per plant ranged from 63 grams for the cultivar `Tristar' to 236 grams for the cultivar `chandler'. Fruit size ranged from 6.8 to 12.3 grams per fruit. Low yield and small fruit size were not commercially acceptable to compete against field production of strawberries.

Impacts
The estimated economic returns from greenhouse cucumber, pepper, and strawberry production were not as good as returns from greenhouse tomatoes. Therefore, it was necessary to focus our resources on greenhouse tomato research to improve production and marketing for Louisiana growers

Progress 01/01/01 to 12/31/01

Outputs
A rapidly increasing domestic market for fresh fruit has stimulated interest in nontraditional cultural practices of strawberries. Off-season production of strawberries in greenhouses is desirable to supply the local market with a high quality fruit that does not ship well to distant markets. Strawberries can be grown in the greenhouse using the vertical system that were developed in Israel. We conducted a variety trial tests using five popular varieties namely `Seascape', `Tristar', `Tribute', `Chandler', and `Camarosa' to determine their yield and fruit size in a vertical growing system. Plants were harvested twice a week for 20 weeks starting around mid-December and were terminated in early May. Total yield per plant was 113, 63, 122, 236, and 208 grams for the varieties mentioned, respectively. Average fruit weight was 9.6, 6.8, 8.3, 12.3, and 12.8 grams.

Impacts
The vertical growing systems that were developed in Israel to produce greenhouse strawberries are expensive to acquire, install, and maintain. Prospective growers should be informed in advance on yield expectations using these systems. Test results should serve as a guide to determine if producing greenhouse strawberries is economically feasible.

Progress 01/01/00 to 12/31/00

Outputs
Greenhouse seedless cucumber is a popular vegetable crop in some states such as Florida. Many retirees use cucumber as a main ingredient mixed with tomatoes in their daily consumption of fresh salad. To evaluate seedless cucumber yield and market acceptance in Louisiana, we conducted a variety trial using four popular varieties namely `Kalunga', `Mariana', `Bologna', and `Cumloude'. The highest yielding cultivar was `Cumloude' followed by `Bologna'. All four varieties produced long, straight, and dark green color. None of the varieties was resistant to powdery mildew disease. Marketing seedless cucumber was not as easy as marketing greenhouse tomatoes in North West Louisiana.

Impacts
The information generated from this research should help greenhouse vegetable growers who want to produce crops other than greenhouse tomatoes.
