RESEARCH UPDATE 1994 FRUIT VEGE LE Wiregrass Added as Site for Southernpea Variety Trials In 1993 the Wiregrass Substation (WS) in Headland joined the E.V. Smith Research Center (EVS) in Shorter and the North Alabama Hor- ticulture Substation (NAHS) in Cullman as trial sites for testing yield potential of Southernpea varieties. Thirty-six varieties and six AAES ad- vanced breeding lines were planted May 4 at WS, May 20 at EVS and June 11 at NAHS. Standard cultural practices were used. Recommendations given in Insect, Disease, Nematode, and Weed Control Recommenda- tions for Commercial Vegetables (Circular ANR-2) were followed for control of pests. To simulate once-over harvesting used by D commercial processors, a single G harvest was made on each plot S M when 80% of the pods were dry. FI In multiple harvest situations, as Fl in pick-your-own and home gar- P dens, yields are usually greater. Yields given in the table were G determined by weighing all Li shelled peas after they were E soaked in water to allow the dry S seeds to absorb water (imbibe) 1993 Squash Variety Trials Held in Clanton and Cullman Twelve varieties of summer squash were direct seeded on bare soil at the North Alabama Horticulture Substation (NAHS) on May 27 and trans- planted on plastic mulched plots at the Chilton Area Horticulture Substation (CAHS) on May 12. At NAHS, each plot consisted of one 42-inch x 20-foot row with an in- row spacing of 12 inches. Plots were fertilized with 13-13-13 at 750 pounds per acre. At CAHS, each plot was 5x20 feet. Preplant fertilizer consisted of 200 pounds per acre as 13-13-13. Sidedress fertilizer was 120 pounds of nitrogen per acre and 240 pounds of potassium per acre. Squash were harvested 11 times between June 29 and August 5 at NAHS, and 14 times between June 7 and July 9 at CAHS. Earliness was evaluated by adding the U.S. #1 grade yields of the first two harvests. J.E:Brown, E.H. Simonne, J.M. Kemble, J.A. Pitts, and M.H. Hollingsworth TABLE 1.

Hunter Moisture Stress Controls Vegetable Transplant Height An AAES study indicates that moisture stress is a viable alternative to the use of growth-regulating chemi- cals to control the height of vegetable transplants. Plugs of 'Big Boy' tomatoes and 'California Wonder' peppers were transplanted on May 15 into cell packs containing one of two commercial media: Fafard #3, a peat moss, pine bark mix; or Pro-Mix BX, a peat moss, perlite mix. Plants were produced in a polyethylene greenhouse. Treatments included moisture stress (MS), two rates of B-Nine (a growth regulating substance), and an untreated control. MS plants were al- lowed to wilt between each irrigation, while the remaining treatments re- ceived irrigation to maintain a moist medium surface. B-Nine treatments were applied until runoff at concen- trations of 2,500 and 5,000 parts per million (ppm). All treatments were initiated on May 22. The 2,500 ppm treatment was reapplied three weeks after the first application. Plant height was determined on June 15. Results showed that while MS is a viable alternative to the use of B- Nine, the effectiveness of the tech- nique is media and species depen- dent. It appears that MS will have a COMBINED 1992 AND 1993 SOUTHERNPEA VARIETY TIMALS SHELLED YIELD Entry Shorter Cullman Headland 1992 1993 1992 1993 1992 1993 Lb./a. Lb./a. Lb./a. Lb./a. Lb./a. Lb./a.

Bush Snap Beans Evaluated for Second Year The second-year trial for 28 bush snap bean varieties selected for their potential to perform well as fresh market and garden varieties in Ala- bama was conducted in 1993 at the North Alabama Horticulture Substa- tion in Cullman. Seeds were planted four inches apart in rows spaced 44 inches apart. Standard cultural practices were followed and rainfall was supple- mented with overhead irrigation when needed to equal one inch per week. All plots were harvested 50 days from planting since home and com- mercial growers look for early, con- centrated yields that can be harvested in a single harvest. Ratings forbean rust were not made due to lack of symptoms in all snap beans tested. Halo blight was present in 17 varieties, but at very low levels. Varieties with consistently moderate yields may be more desir- able than those with high yields one year, but low yields the next. Hialeah, Wrangler, FM-359, Magnum, NUM- 0820, Venture, and Jumbo were among the ten highest yielding varieties in 1992 and 1993. A.G. Hunter, M.H. Hollingsworth, and O.L.

Plots consisted of 10 hills with an in-row plant spacing of six feet and between-row plant spac- ing of 88 inches at all locations, except at the Gulf Coast Substation where between-row plant spacing was 10 feet. Watermelons were grown according to standard fer- tilizer and pesticide recommenda- tions. All trials were irrigated as needed. G.E. Boyhan, J.D. Norton, B.R. Abraham, J.A. Pitts, E.L. Carden, M.H.

Average yields obtained with new varieties were similar to or higher than standard varieties. At the E.V. Smith Research Center (EVS), raised beds with five- foot between-row spacings were planted May 24. Within row spacings were one-foot at all locations. Plots were harvested 113 days after plant- ing. Sixty pounds of nitrogen (N) fer- tilizer [Ca(N03)2] were applied at planting, along with P 2 0 5 and K 2 0 (60 pounds per acre each). An addi- tional 20 pounds of N were applied eight weeks after planting. Rainfall during the season was 11 inches. Irri- gation was applied twice, 1.5 inches each time.

Smith Research Center (EVS) in Shorter, at the Chilton Area Horticulture Substation (CAHS) in Clanton, and at the Sand Mountain Horticulture Substation (SMHS) in Crossville. At CAHS, corn was planted on May 17 in three-row plots. Plots were 2.5x20 feet with seeds spaced 28 inches apart. Before planting, 1,000 pounds of 5-10-15 per acre were applied, and an additional 100 pounds of nitrogen (N) as ammonium nitrate were sidedressed. Lannate and Bravo were applied at a two-pint per acre rate. The ears were harvested on July 22 and July 28. All trials were irrigated. At EVS, plots were fertilized preplant with 100 pounds of N per acre as calcium nitrate and 60 pounds of potassium per acre as muriate of potash. Plots were later sidedressed with anhydrous ammonia at 50 pounds of N per acre. Preplant herbicides were Sutan (four pints per acre) and Atrazine (1.5 pints per acre). Corn was planted on May 26 in 2.5x20-foot rows. Plots contained four rows, and the two center rows were harvested. Lannate was applied periodically at two pints per acre and Pounce at four ounces per acre. Plots were harvested on July 30 and August 4. At SMHS, corn was seeded on May 5. Preplant fertilizer consisted of 13-13-13 at 430 pounds per acre, and an additional 148 pounds of N per acre was sidedressed. Preplant herbicide was Atrazine at two quarts per acre.
