Turkish Journal of Agriculture and Forestry
Deficit plant nutrients, especially nitrogen, and weed competition are the most critical problems in organic farming. This research was carried out on research plots of the Agricultural Research and Extension Center of Atatürk University Agricultural Faculty during the cropping seasons of 2006-07, 2007-08, and 2008-09 under dry farming conditions. A factorial experimental design with 4 replications was used to set up the experimental plots. The factors were 2 wheat cultivars (Kırik and Doğu-88), 3 weed control practices (weedy control, hand weeding, dense sowing), and 7 fertilizer sources [control, standard inorganic (NP), Bio-Organic (Bio), Bio-SR Organic (Bio SR), Leonardite, Organic fertilizer …

Turkish Journal of Agriculture and Forestry
Microsatellite regions in DNA fragments of Gossypium arboreum were explored and PCR products 500-800 bp long were analyzed for genomic simple sequence repeats (gSSRs). From 39 segments, 23 short gSSRs were identified; on average they occurred every 1.6 kb. Primers were used to amplify fragments from 18 diploid species representing 6 diploid genomes and 1 tetraploid species, G. hirsutum (AD). The phylogeny of diploid genomes was subsequently determined. No primer amplified the DNA from all genotypes; however, amplification occurred in 59% of 437 PCR events. All genomes were grouped into 2 clusters (a and b). The obtained phylogeny of the …

Turkish Journal of Agriculture and Forestry
Hypericum triquetrifolium is a promising medicinal plant from eastern Europe and the Mediterranean area. The present study was conducted to determine ontogenetic and morphogenetic variation of chlorogenic acid, rutin, hyperoside, isoquercetin, quercitrin, and quercetin content in this species. The wild-growing and greenhouse-grown plants were harvested at vegetative, floral budding, full flowering, fresh fruiting, and mature fruiting stages and were dissected into stem, leaf, and reproductive tissues, which were dried separately and subsequently assayed for bioactive compounds by high performance liquid chromatography. Chemical contents in whole plants increased during plant phenology and, generally, higher accumulation levels were observed in wild plants. …

Land Suitability Assessment For Rice Cultivation Based On Gis Modeling, Orhan Dengi̇z
Turkish Journal of Agriculture and Forestry
The main objective of this study was to develop a spatial model for land suitability assessment for rice (Oryza sativa L.) cultivation using geographic information system (GIS) techniques. The land mapping units, resulting from the overlay of the selected theme layers, have unique land quality information, on which land suitability is based. Results showed that 55.5% of the study area is highly or moderately suitable for rice cultivation, whereas 34% of that area is unsuitable for rice cultivation due to soil and topographic conditions. The model was also validated with field studies. According to the statistical analysis, there was a …

Turkish Journal of Agriculture and Forestry
Dacryodes edulis, with its potential dietary and medicinal uses, is an aging member of the agroforestry system and is classified among the priority species for domestication in Central Africa. Reliable techniques for producing quality planting materials other than seeds are urgently needed. The aims of this study were to produce D. edulis layers and integrate them into the cropping system. To promote rooting and the survival rates of layers, 4 treatments were used. The layers produced were inoculated with mycorrhiza and introduced into cropping systems for the evaluation of morphobiochemical parameters. The results show that 67.91% of D. edulis trees …

Survival of inoculants in grass silages may enable them to improve the quality of silages through enrichment with polyunsaturated fatty acids (PUFAs). The effects of 2 inoculants, Enterococcus faecium 2/3s (EF2/3s) and E. faecium 26/42 (EF26/42), on nutrient composition, fermentation parameters, and fatty acid content in grass silages during ensiling (111 days) of fresh grass (G) were examined under laboratory conditions. The G [285 g of dry matter (DM) kg^{-1}] was ensiled in 36 polyethylene jars (1 L) divided into 3 × 12 sets per treatment and ensiled at 21 °C for 111 days. The 3 silage treatments used were: …

Turkish Journal of Agriculture and Forestry
It is commonly believed that furniture spring systems are far more durable and friendly to use than foam systems. The aim of this research project was to design and realise models of individual auxetic compression springs and determine their resistance to cyclic as well as prolonged static loads. The study was conducted using numerical calculations and verification of results by laboratory experiments. The results of the performed investigations made it possible to conclude that the designed spring had stiffness characteristics similar to the compression characteristics of polyurethane foams. Cyclical and prolonged static loads have no significant influence on changes in …

Tolerance And Avoidance Responses To Salinity And Water Stresses In Calotropis Procera And Suaeda Aegyptiaca, Ali Hassan Ibrahim
Turkish Journal of Agriculture and Forestry
This study was designed to evaluate the response of 2 wild shrubs, Calotropis procera and Suaeda aegyptiaca, to salinity (100% seawater), drought, and waterlogging stresses. The 90-day-old plants were subjected to the stress treatments for 3 weeks, and growth and some physiological parameters were evaluated. The total plant dry mass of C. procera plants was reduced by 40%, whereas S. aegyptiaca was not significantly affected by salinity stress. Water deficit and waterlogging stresses significantly reduced the total dry mass of both species. Under all conditions, the root/shoot ratio in C. procera was 3-fold higher than in S. aegyptiaca. All applied …

Dairy and meat production are very complex in dry regions due to shortages and the low quality of fodder, especially in dry months. Livestock scientists are enthusiastic to explore and investigate good quality fodder that can boost milk and meat production in an economical way. Moringa oleifera is known as one of the best fodder crops for dry regions with scanty amounts of water. Hence, the present study was designed to evaluate the potential of Moringa oleifera as a field crop by harvesting at different cutting heights (30, 90, and 150 cm).

This study was designed to find correlations between the rate of nitrogen and potassium and basil herb quality resulting from essential oil content and composition. An increase in the amount of nitrogen in the nutritional environment of the plants resulted in the enhanced accumulation of essential oil, as well as in a rise in linalool and germacrene D concentration. The present study also showed increased content of essential oil in the herb, as well as an increase of 1,8-cineole in the oil under the influence of the increased rate of potassium. The studied basil cultivars Kasia and Wala were characterized …

An Axr1 Suppressor Mutation In Arabidopsis That Partially Restores Auxin Signaling Also Reverses Defects In Jasmonate Response, İskender Ti̇ryaki̇, Paul E. Staswick
Turkish Journal of Agriculture and Forestry
The Arabidopsis mutant axr1 is defective in both auxin and jasmonic acid responses. A screen for axr1-24 suppressors yielded sar1-5, an allele of previously described mutants that partially correct the auxin response defects in axr1. The new allele partially suppresses defects in jasmonate response in axr1. The JA concentration required for 50% inhibition of seedling root growth was 5-10 µM for axr1-24 sar1-5. This was at least 10-fold less than that required for axr-24, but 5- to 10-fold higher than for WT. In the axr1-24 background sar1-5 also partially restored resistance to the soil fungus Pythium irregulare, a trait known …
