However, situations oc- cur every year in which cotton is injured by these herbicides. Experiments were conducted recently at the Alabama Agricultural Experiment Station's E. V Smith Research Center in Shorter, Tennessee Valley Substation in Belle Mina, and Wiregrass Substation in Headland to determine the effects of 2,4-D, dicamba, and 2,4-DB on cotton yields. At Shorter, 2,4-D rates of 0.0001, 0.001, 0.01, and 0.1 lb. per acre were ap- plied to cotton in the early squaring stage in the first year and to cotton in the late bloom stage the following year. At Belle Mina and Headland, 2,4-DB was applied at rates of 0.001, 0.01, 0.1, and 0.5 lb. per acre, while dicamba and 2,4- D were each applied at rates of 0.01 and 0.1 lb. per acre. All herbicide rates were applied independently to cotton in the six-leaf stage and first bloom stage dur- ing 1986. Lower rates (0.01 lb. and lower) simulated drift or contaminated spray tanks. Dry conditions occurred at Shorter and Headland when these trials were conducted, while rainfall at Belle Mina was close to average. Low volatile formulations of all three herbicides were used. Herbicides were sprayed over the top of cotton in 15 gal. of water per acre. TABLE 1. EFFECTS OF FOLIAR APPLICATION OF 2,4-D ON YIELD OF SEED COTTON IN A TWO-YEAR TEST AT THE E.V.

Rates of 2,4-D lower than 0.01 lb. per acre did not decrease yields when applied to squaring cotton in the first year. In the second year, rates of 2,4-D lower than 0.1 lb. per acre did not decrease yields when applied to cotton during late bloom. However, application of 0.1 lb. per acre to cotton in late bloom at Shorter reduced yields 34% in the sec- ond year. When averaged over all rates of appli- cation, 2,4-DB treatments at the six-leaf stage reduced yields 49 and 48%, re- spectively, at Belle Mina and Headland, table 2. First bloom applications re- duced yield 69% at Belle Mina, but only 25% at Headland. The yield potential of cotton was significantly lower at Head- land than Belle Mina due to dry condi- tions, which slowed translocation of 2,4-DB in the plant and possibly ex- plains the yield difference. The average yield reduction increased from 9 to 83% as 2,4-DB rates increased at Belle Mina and Headland, table 3. Comparing yield reductions of the three herbicides at equal rates shows 2,4-D to be more injurious than 2,4-DB or di- camba when all were applied at 0.01 lb. per acre (50% vs. 33% and 27%, respec- tively). However, at 0.1 lb. per acre, 2,4-D and 2,4-DB were equally inju- rious to cotton yields, while dicamba was somewhat less harmful (64 and 61% vs. 52%, respectively). Nevertheless, each herbicide severely reduced yields at the 0.1 lb. per acre rate. Yield reductions ob- tained were primarily due to a decrease in boll number per plant and percent open bolls as herbicide rates increased. Typical spray tank contamination or drift could easily contain 0.01 lb. per acre of 2,4D, 2,4-DB, or dicamba, and even this low rate could reduce yields enough to eliminate any profit from a cot- ton crop.

Comi parI d to( Com())IparIedi to pr- .peimcit pos -c fuci e t m e Insufficient Dietary Fiber Intake Is a Problem among the Elderly R.E. KEITH and L.M. VARNER DIETARY FIBER consump- tion is currently a hot topic among health conscious in- dividuals. The press regularly reports that dietary fiber may contribute to the prevention and/or relief of several common chronic diseases and disor- ders (constipation, obesity, diabetes, high blood cholesterol levels, diverti- cular disease, and colon cancer). It is now known that dietary fiber is not a single substance, but several sub- stances, each with a slightly different function. Thus, dietary fiber from raw fruits and vegetables may have differ- ent effects on the body when com- pared to the dietary fiber in beans, oatmeal, or various bran products. Despite all the reports about fi- ber's importance, the nation's elderly seem to be largely unaware of the facts and may not consume enough fi- ber to fill their needs. This is espe- cially meaningful because elderly per- sons frequently suffer from diseases or disorders associated with poor eat- ing habits, including a possible lack of dietary fiber. The magnitude of the problem is em- phasized by population data showing that persons over 65 years of age cur- rently make up approximately 11-12% of the total U.S. population. And this per- centage is expected to increase signifi- cantly over the next 20-40 years. Due to the increasing numbers of el- derly persons and the lack of substantial data concerning dietary fiber intake in elderly persons, a study was conducted by the Alabama Agricultural Experiment Station. The purpose was to determine the dietary fiber intake and knowledge of food sources of dietary fiber in a group of apparently healthy elderly men and women. Subjects in the study included six men and six women ranging in age from 60 to 88 years. Participants all lived in a re- tirement mobile home community, had completed at least a high school educa- tion, were married, and had full kitchen facilities available to them. All had re- tirement incomes above established pov- erty levels. Data related to health status; fiber intake, knowledge of dietary fiber sources, and lifelong dietary habits were obtained by personal interview in con- junction with written questionnaires and a 24-hour diet recall. Height, weight, and 24-hour dietary fiber intake data for the 12 subjects are reported in table 1. Daily dietary fiber intake in the group ranged from 4 to 23 grams', with an av- erage intake of 11.7 grams per day. Rec- ommended dietary fiber intakes range from 15 to 35 grams per day. Thus, the dietary fiber intake in the study group of elderly could be characterized as low. The low fiber diets of those surveyed are apparent in data-in table 2. Raw and cooked fruits and vegetables were the high fiber foods most often eaten by the elderly respondents. The fiber intakes were characterized by the consumption of several foods containing some fiber 'One ounce = approximately 28 grams. rather than concentration of one high fiber food such as bran. Two-thirds of the subjects could not recall ever receiving any professional or public information on dietary fiber. This finding was supported by the re- sults of the dietary fiber knowledge questionnaire. A number of the sub- jects were familiar with several good sources of dietary fiber (raw fruits and vegetables, bran). However, none of the subjects knew that whole grains, beans, nuts, or seeds were good sources of fiber. In addition, several participants thought that low fiber foods, such as meat, white bread, milk, and yogurt, were good sources of fiber. Results indicated that there was an inability to consistently and correctly identify high and low fiber foods. In addition to the dietary fiber data, health status results indicated that a high percentage of the subjects had at least one of the following disorders related to low fiber diet: constipation, obesity, diabetes, and diverticular disease. While the con- sumption of a low fiber diet cannot be di- rectly implicated in the diseases noted, conditions associated with low fiber diets were found in the present group of el- derly. Data on subjects in the present study indicate that most had dietary fiber in- take below or at the low end of the rec- ommended fiber intake range. The fiber consumed by the elderly subjects was mainly from a variety of fiber sources rather than one major source such as bran. Subjects could identify certain high fiber foods; however, they could not consistently and correctly identify high and low fiber foods. Obesity, constipa- tion, diabetes, and diverticular disease were low fiber intake-related disorders which afflicted some of the participants. These findings emphasize the need to in- crease dietary fiber consumption and knowledge in the elderly. Keith is Associate Professor of Nutrition and Foods and Varner is a Graduate Student. Alabama Agricultural Experiment Station AS MARK TWAIN said about the erroneous reports of his death being greatly exaggerated, so it can be reported that neighborhoods are alive and functioning in Alabama. This finding by the Alabama Agricultural Ex- periment Station and Tuskegee Univer- sity disputes the many gloomy reports about unhealthy conditions of rural and urban neighborhoods today. A basic social unit, the neighborhood is often overlooked in social science re- search because it is not a political entity that has members or elects officers. In- stead, the neighborhood is a locality group that exists as a result of people (families or households) building houses and making their homes near one an- other. Although relatives sometimes live in the same neighborhood, the most common pattern is for the residents to be strangers prior to moving into an area. Much has been written recently about the deterioration or disappearance of neighborhoods as meaningful social units in American society. Concern has focused on farm neighborhoods as well as city neighborhoods. In cities, families living in close proximity are believed to have little social interaction-to interact less frequently and with fewer neighbor families than was true in the past. Simi- lar changes are believed to be occurring in rural areas. Farms have grown larger and fewer. Rural residents no longer share a common occupation and attach- ment to agriculture. Many local people commute to jobs in town and their chil- dren leave the neighborhood to attend school. The result is a greatly restricted set of interactions characterizing social life at the neighborhood level. What types of social interactions are most reflective of neighborhoods? Most would probably agree that "neighbor- ing" best describes these interactions because they involve face-to-face con- tacts on a continuing basis over a long pe- riod with people and families who live nearby. Not every family in a neighbor- hood needs to "neighbor" with every other family. Some families may live near others and not interact, or interact only selectively, with neighbors; yet through this network of interactions among fami- lies, a sense of neighborhood exists. The study reported here measured the strength of neighboring in different types of locational settings: open coun- try, small town (2,500-10,000), city (10,000-50,000), and metropolitan city (50,000 or larger). Neighboring was de- fined as the frequency with which the members of a household or family have contact with other households living nearby. Data were gathered in a 1985 statewide survey of more than 1,600 Ala- bama households. Neighboring interactions studied in- cluded: (1) going places together, (2) en- tertaining one another in each others' homes, (3) asking each other advice, (4) talking about problems, (5) borrowing things from each other, (6) visiting in each other's homes, and (7) watching out for each other. Average household neigh- boring scores are shown in the table for each type neighborhood interaction. The results reveal that some behaviors identified as common within the neigh- borhood setting are practiced more often and by more Alabama households than are others. "Going places" with neigh- bors and reciprocated "entertaining in each other's homes" are least often prac- MEAN SCORES FOR SEVEN NEIGHBORING BEHAVIORS PRACTICED BY ALABAMIANS IN FOUR RESIDENTIAL SETTINGS Neighboring Neighboring scores, by residential settings behaviors Open Town City Metro State- country 2,500-10,000 10,000-50,000 50,000+ wide Going places together.............. 1.35 1.20 1.10 1.11 1.23 Entertaining one another in each other's homes .................. 1.37 1.17 1.18 1.23 1.28 Asking eachother advice........... 1.61 1.49 1.51 1.55 1.56 Talking about problems . ........... 1.62 1.56 1.52 1.58 1.58 Borrowing things from each other .... 1.81 1.71 1.60 1.60 1.71 Visiting in each other's homes ....... .1.95 1.85 1.76 1.73 1.86 Watching out for each other ........ 2.49 2.46 2.47 2.51 2.49 'Item scores are based on scores and responses of 0= never, 1= rarely, 2 = sometimes, and 3= often. ticed statewide. Conversely, the most common neighboring behavior is to "watch out for each other." More than 60 percent of households indicated that they often watched out for their neighbors. Visiting in neighbors' homes also was a fairly common behavior with 25 percent visiting often. Rural or open-country families were more likely to experience a wider variety of social contacts with others living in their neighborhoods and to neighbor more often than were families living in other residential settings. Much neigh- boring occurs in metro neighborhoods, but people living in open-country neigh- borhoods consistently had the highest average neighboring score. Comparison of average scores for the seven neighboring behaviors reveals that open-country neighboring patterns are different from city and metro residents on going places together, borrowing things from each other, and visiting in each other's homes. For each behavior, open-country people were more likely to neighbor this way than were city or metro residents. The only other signifi- cant difference was observed between open-country and town or city residents regarding entertaining one another in each other's homes. In this instance, res- idents of metro neighborhoods were more likely than either town or city res- idents to neighbor in this way. What can be concluded from these findings? Reassuringly, they reveal that much neighboring is going on today in neighborhoods across Alabama. At the same time, the strength or intensity of neighboring today does vary depending on the type of residential setting. These findings suggest that open-country neighborhoods are probably best able to respond to crisis in times of emergency or need and to organize effectively for lo- cal voluntary projects because of their traditional patterns of neighboring inter- action.

However, establishment has been a prob- lem due in part to poor seedling vigor which limits competitiveness with weeds, particularly during the first year. If weed competition could be reduced during the year of planting, then stand survival should be increased to provide acceptable stands for forage or seed pro- duction. Research to solve the weed problem was begun at the Alabama Agricultural Experiment Station. The first step was to evaluate lespedeza's tolerance to com- monly used herbicides. These experi- ments led to the conclusions that (1) ser- icea lespedeza is more tolerant to postemergence than preemergence ap- plied herbicides, and (2) herbicides showing best weed control and least in- jury to sericea were 2,4-DB, 2,4-D, and Fusilade ?. The next step was evaluation of several postemergence weed control systems on AU Lotan and 73-162-19, a soon-to-be- released, low-tannin sericea lespedeza. Experiments were conducted at the E.V. Smith Research Center in 1985 (planted May 27) and 1986 (planted May 21) on a Norfolk loamy sand soil. Another exper- iment was conducted at the Prattville Experiment Field during 1986 (planted May 28) on a Lucedale fine sandy loam. Treatments included 2,4-DB amine at 1/2 lb. acid equivalent (a. e.) per acre and 2,4-D amine at 1/4 lb. a.e. per acre ap- plied one, two, or three times. The first application was applied 14 days after planting (DAP) to lespedeza that aver- aged 1/2 in. in height. The second and third applications, where appropriate, were applied to lespedeza that averaged 12 in. (28 DAP) and 51/2 in. (42 DAP) in height, respectively. All these systems were designed for control of broadleaf weeds. Grass weeds were eliminated by treating all experiments with two appli- cations of Fusilade at 3/8 lb. active ingredient (a.i.) per acre per application plus crop oil (2 pt. per acre per applica- tion). The first and second applications were applied 14 and 28 DAP, respec- tively. A hoed check and a weedy check were included for comparison. Treatments were evaluated by esti- mating control of broadleaf weeds and by recording lespedeza stem height, stems per plant, seed yield, and germination.

'Broadleaf species at E.V. Smith Research Center were sicklepod, coffee senna, and annual morning- glories. Species at Prattville Field were sicklepod, annual morningglories, common purslane, and pros- trate and spotted spurge. 4 First-year yield is from an experiment at E.V. Smith Research Center that was established and treated in 1985. The second year is the same experiment but treated againin 1986. First-year seed yields were obtained on a 1985 experiment at the E.V. Smith Re- search Center and on a 1986 experiment at the Prattville Experiment Field. Sec- ond-year seed yields were obtained at the E.V. Smith Research Center (exper- iment received identical treatments in 1985 and 1986). A portion of these data is presented in the table. AU Lotan and 73-162-19 were tolerant to both 2,4-DB and 2,4-D applied as many as three times per season. Neither stem height nor stem number was re- duced by herbicides. Lespedeza plants receiving either 2,4-DB or 2,4-D were actually taller with more stems per plant when compared to the weedy check. The plants at the Prattville Field were much shorter than at the E.V. Smith Research Center, due primarily to water stress. However, stem number per plant was al- most identical for both locations. Good to excellent broadleaf weed con- trol was obtained with either two or three applications of 2,4-DB or 2,4-D at both locations. The two applications of Fusilade + crop oil eliminated annual grasses and produced no adverse effects on either cultivar. In general, first-year seed yields were slightly higher for AU Lotan than 73-162- 19. This was due in part to an overall bet- ter stand of AU Lotan. Lespedeza treated with either two or three appli- cations of 2,4-DB or 2,4-D produced seed yields equivalent to the hoed checks. Second-year seed yields of both culti- vars were highest when either 2,4-DB or 2,4-D was applied two or three times. Controlling broadleaf weeds essentially doubled seed yields the second year. Neither herbicide affected seed germi- nation. Jones is Graduate Student and Walker is Associate Professor of Agronomy and Soils.

This system produces chops and steaks that look and taste more like stan- dard muscle meat than products formed from ground or flaked meat. The value of this development is that it offers a chance for better utilization of low grading beef and pork carcasses and opens the door for cashing in on the "fast food" market. There have been problems, of course, with restructured products. For exam- ple, the prevalence of connective tissue in less desirable cuts used in restruc- tured products results in toughness of the final product. This connective tissue could be trimmed away, but this ap- proach is too costly. Mechanical and en- zyme tenderization treatments have been tried with varying degrees of suc- cess. The latest study at the Alabama Agri- cultural Experiment Station found that either mechanical tenderization or addi- tion of food-grade enzymes improves tenderness of restructured beef cuts. However, the greatest improvement to tenderness resulted when both mechan- ical tenderization and enzyme additions were used.

Rounds from Utility grade cow car- casses-with briskets providing the fat- were used for the study. Muscles for the mechanically tenderized treatments were passed through a blade tenderizer four times and then ground through a three-hole, kidney-shaped plate (1-in. X 2.5-in.). Control muscles (non-tender- ized, no enzyme) were ground through the same size kidney-shaped plate. The fat component for the restructured steaks was obtained by grinding boneless briskets and mixing for 3 minutes to ran- domly distribute fat. The fat portion was divided into two equal portions for in- corporation into steaks for the tenderized and non-tenderized treatments. Four treatments were prepared from the lean and fat components described: (1) control, no mechanical tenderization, no enzymes added, (2) mechanically ten- derized, no enzymes added, (3) mechan- ically tenderized, enzymes added, (4) enzymes added, no mechanical tenderi- zation. Nine-pound chunks of lean meat from the rounds were mixed with 0.75% salt, 0.25% sodium tripolyphosphate, and 2% water in a bowl mixer for 2 minutes. The fat portion (41/2 lb.) from briskets was added to the mixer and mixed for another 4 minutes. For enzyme-treated samples, 100 p.p.m. papain and 50 p.p.m. ficin were dissolved in the 2% water, and added to the meat during the initial stage of mixing. The meat mixture was stuffed into 4- in.-diameter casings and frozen (-10?F) for 24 hours. The frozen logs were tem- pered for 24 hours at 26?F, then pressed into a uniform shape and sliced into 3/4- in.-thick steakettes. These steaks were interleaved with waxed paper, sealed in plastic bags, placed in wax-lined card- board cartons to simulate commercial storage conditions, and stored at -10?F for subsequent analyses. Restructured beef steaks were cooked on a grill to an internal temperature of Auburn Restructuring Process Transforms Utility Beef into Tender Steaks Y.H. CHU, D.L. HUFFMAN, and W.R. EGBERT sor, and Egbert is Research Associate of Animal and Dairy Sciences. Alabama Agricultural Experiment Station 158?E Cooked steaks were randomly se- uble collagen (protein component of con- nective tissue) content analyses. Restructured steaks treated with the combination of mechanical tenderization and enzyme addition had the greatest cook loss. Samples which had been me- chanically tenderized also had a high percentage of cook loss, however, there were only small differences between the control and mechanically tenderized treatments. Samples with enzymes added (no mechanical tenderization) were not different in cook losses com- pared with the control. Both mechani- cally tenderized treatments showed higher cook losses than the control or en- zyme treatment. This may be due to rupturing of the muscle cells by the needles during the tenderization pro- cess. Results of tensile strength tests (In- stron readings) indicate that the control treatment resulted in the best bind (force holding meat together). The me- chanically tenderized treatment (no en- zymes added) had better binding char- acteristics than the enzyme treated samples. Enzyme treated samples re- quired the least amount of force to pull the meat apart. Tenderness of meat mass was in- creased by either mechanical tenderiza- tion or enzyme addition. The greatest in- crease in tenderness, however, resulted from a combination of mechanical ten- derization and enzyme addition. Mechanical tenderization decreased both tensile strength and shear force. The addition of enzymes resulted in de- creased force values, along with losses of physical texture. Values for tensile strength (Instron readings) and shear (Kramer readings) showed enzyme deg- radation of the muscle protein. Another test done was the assay of sol- uble collagen. This showed that the en- zyme addition increased the solubility of collagen, which is another measure of tenderness. From this study it can be concluded that a processor can use less desirable cuts of meat to produce a restructured product that will have desired tender- ness. This can be accomplished by use of mechanical tenderization and the addi- tion of food-grad e enzymes.
