Withdrawal Strength Of Dowels In Plywood And Oriented Strand Board, Yusuf Zi̇ya Erdi̇l, Carl A. Eckelman Jan 2001

Withdrawal Strength Of Dowels In Plywood And Oriented Strand Board, Yusuf Zi̇ya Erdi̇l, Carl A. Eckelman

Turkish Journal of Agriculture and Forestry

Plywood and oriented strand board (OSB) are being used increasingly in the construction of upholstered furniture frames. Yet there is little information available concerning the holding strength of various fasteners, and, in particular, dowels in these materials. A study was conducted accordingly, to obtain basic information about the holding strength of dowels in both plywood and oriented strand board. Results of the tests were incorporated into predictive expressions that allow designers to estimate withdrawal strength as a function of the diameter of the dowels, their depth of embedment and the density of the composite material. Given the variability of the …

Effects Of Different Seeding Rates And Cutting Times On The Forage Yield And Forage Quality Of Autotetraploid Perennial Rye (Secale Montanum Guss.), İlknur Akgün, Meti̇n Tosun, Mahmut Taşpinar, Sevi̇m Sağsöz

Turkish Journal of Agriculture and Forestry

This research was carried out in 1995-97, in Erzurum ecological conditions, in order to study the effects of different seeding rates (100, 200, 300, 400 and 500 seeds/m^2) and cutting times (at shooting, boot, heading and flowering stages) on hay yield and quality. The effects of seeding rates on fresh and dry hay yields, crude protein content and crude protein yield were significant while P, Ca, Mg, K, and ash contents and tetany value were not significant, based on the research. According to cutting times, all characteristics examined showed significant differences. Delayed cuttings applied at the flowering stage reduced fresh …

Evaluation Of Yield And Yield Components In Inbred Maize Lines I. Heterosis And Line X Tester Analysis Of Combining Ability, Şevket Meti̇n Kara

Turkish Journal of Agriculture and Forestry

In maize, three male testers and six female lines together with their 18 F_1 hybrids were evaluated to study the general and specific combining ability estimates and heterosis following line x tester approach. Analysis of variance indicated the existence of significant variation among F_1 and parents for all characteristics. Average heterosis was significant for all characteristics studied and was positive, except for days to tasseling, with the average yield of hybrids being 79.8% above that of the parents. In view of the general combining ability effects of the parents, the parental lines YUZ P709 and FR 64A were identified as …

Determining Irrigation Possibilities And Agricultural Problems In The Wheat Growing Areas Of Ankara, Konya And Eskişehir Provinces, Zeynep Dernek

Turkish Journal of Agriculture and Forestry

This study was conducted to determine the agricultural technical conditions and irrigation systems for obtaining high yields in wheat production. A questionnaire was prepared and applied to farmers growing wheat in Ankara, Konya and Eskişehir in 1996. After analyzing the data, we determined the water resources, the amount of water used for wheat production, the allocation of crops, and the technical and financial problems faced by farmers in the research area. The findings of the study showed that 74% of irrigation water is high quality, and ground water and surface water are used in almost equal amounts. Depending on the …

Department of Agronomy and Horticulture: Faculty Publications

Twenty-three entries of grain sorghum (Sorghum bicolor (L.) Moench), including eight inbred lines (five males and three females) and 15 hybrids, were evaluated to determine the proportion of γ, αII, and β-αI-kafirins and their association with contents of crude protein, fat, and starch; protein digestibility; in vitro dry matter disappearance; and seed weight. The male lines included three normal-seeded lines (TX2737, TX435, and P954063) and two large-seeded lines (Eastin1 and PL-1). Female lines consisted of three common U.S. seed parent lines (Wheatland, Redlan, and SA3042). The lines and their hybrids were grown under dryland conditions at two locations in …

Seed Physiology, Production & Technology: Germination, Emergence, And Yield Of 20 Plant-Color, Seed-Color Near-Isogenic Lines Of Grain Sorghum, Jeffrey F. Pedersen, J. J. Toy

Department of Agronomy and Horticulture: Faculty Publications

Although there is growing demand for sorghum [Sorghum bicolor (L.) Moench] with white seed and tan plant color, there is limited information on the overall agronomic fitness of sorghum with these characters. A set of experiments was conducted to evaluate the combined effects of plant color and seed color on sorghum germination, emergence, and agronomic performance. Twenty near-isogenic lines with red seed/tan plant (RT), red seed/purple plant (RP), white seed/ tan plant (WT), white seed/purple plant (WP) phenotypes were tested under field and laboratory conditions. Plant color X seed color interactions were not significant. Purple plant color phenotypes had higher …

Turkish Journal of Agriculture and Forestry

This trial was conducted on the experimental fields of the Agricultural Faculty at Atatürk University in 1987-92 and five-year results were evaluated except for the first year. The effects of different row spacings (20, 30 and 40 cm), cutting stubble heights (2.5, 5.0 and 7.5 cm) and stubble burning on seed yield and yield components of crested wheatgrass (Agropyron cristatum) were studied. According to five-year averages, the effects of row spacings on the seed and straw yield, reproductive shoot number per m^2 and seed number and weight per spike were significant.

Serving Size And Gender Effects On Product (Lemonade) Acceptance And Just-Right Attribute Ratings, Zehra Ayhan, Chen-Ta Li, Matrid K. Ndife, Q. Howard Zhang

Turkish Journal of Agriculture and Forestry

The serving size and gender effects on product acceptance and ideal attribute (lemonade flavor, sourness and sweetness) ratings of lemonade were investigated using a 15-point hedonic scale and a 5-point just-right scale, respectively. Females (67) and males (68) consumed a 4 oz (118 ml) sample ad libitum, or a full 8 oz (236 ml) serving. Ad libitum male consumption was not different (p>0.05) from female consumption. A low correlation (R^2=0.011) was observed between the amount of lemonade consumed and product acceptability or just-right attribute ratings. Neither serving size nor gender had an effect on the overall acceptability (p>0.05). …

Turkish Journal of Agriculture and Forestry

In this research, the adaptation and ground cover properties of some plants with aesthetic and functional features, found in the natural flora of the province of Trabzon, were investigated. Nineteen different natural ground cover plants from 8 families were chosen as trial plant material. These materials, which were mostly from the alpine zone, were planted as plugs in 1994. Survival rates and plant cover area were recorded and measured at the beginning of the vegetation season, during flowering, and at the end of the vegetation season in 1995 and 1996. Moreover, observations were made on some of the morphological properties …

The first consideration prior to seeding is to determine the present level of management being applied to the proposed site. Many sites will recover or improve without seeding if proper management is implemented. Soil is the primary natural resource and its conservation is the most important consideration in seedings.
