  This study was carried out in Elmacayır Pasture, Yesilyurt County of Malatya/Turkey in 2002-2003 period. In order to determine pasture position, the parcel of pasture was established by soil analysis. Thus, botanical composition, hay yield and plant covered area was determined as well. In Hay yield, the percentage of plant covered area and the rate of good type pasture plant Elmacayır Pasture was divided into three regions as First, Second and Third Region. Hay yield, percentage of plant covered area and good type pasture of these three region were determined. In First region hay yield was determined as 1239.4 kg ha-1, percentage of plant covered area as 35% and good type pasture plant rate as 20.9%. In Second region hay yield was determined as 1643.1 kg ha-1, percentage of plant covered area as 64% and good type pasture plant rate 16.3%. In third region hay yield was determined as 1619.9 kg ha-1, percentage of plant covered area as 47% and good pasture plant rate as 33.4%. It has been determined that the state of the first and the second pasture regions are poor, that of the third region is medium. It has also been fixed that each region indicates arid-pasture feature.

  A field experiment was conducted during 2005-06 and 2006-07 growing seasons in Van, Turkey, to determine the effects of Rhizobium inoculation and different levels of phosphorus on the yield and nutrient uptake of field pea (Pisum sativum sp. arvense L.). Phosphorus application had significant effect on the plant height, number of branches, root and shoot dry weight, number of nodule, seed and biomass yields, number of pod, crude protein rate and phosphorus content of seed in both years. There was linear increase in the root dry weight, nodule number, crude protein rate and phosphorus content of seed up to 90 kg P2O5 ha-1 application. The highest seed yield was obtained under treatment 60 kg P2O5 ha-1+ inoculation with 2855.0 and 2828.3 kg ha-1 in 2005-06 and 2006-07, respectively. Plant height, number of branches, shoot dry weight, number of pod, seed and biomass yields increased up to 60 kg P2O5 ha-1 and then decreased at 90 kg P2O5 ha-1. Inoculation treatment had also significant effect on the plant height, number of branches, root and shoot dry weight, number of nodules, seed and biomass yields, number of pod, crude protein rate and phosphorus content of seed in both years. The highest values regarding these parameters were obtained from inoculated plants, whereas the lowest values were obtained from the uninoculated plants.

  This research was conducted on a farmer’s field in Erciº (Van), Turkey in 2001 and 2002. Four forage plants-Garden Burnet, Sainfoin, Crested Wheatgrass and Sheep Fescue were used in the study. Six mixtures were prepared, each comprised of 25% crested wheatgrass and 25% sheep fescue, but with variations in sainfoin and garden burnet ratios of 0-50, 10-40, 20-30, 30-20, 40-10 and 50-0%. Study results found that the highest hay and crude protein yields (1111 and 180 kg ha 1, respectively) were obtained with the mixture consisting of 25% crested wheatgrass, 25% sheep fescue, 30% garden burnet and 20% sainfoin. This mixture rate can be recommended for use on artificial rangelands established in drought areas in semiarid regions throughout the world.

  This study has been carried out in Karpuzalan and Ad guzel districts of Van province between the years 2006 and 2007. At the beginning, questionnaires have been conducted in order to learn what kind of plants is used for which purpose by the villagers. After this, these plants have been collected from the fields and identified in Yuzuncu Y l University, Faculty of Science and Letters, Department of Biology and they have been included in herbarium. Later, the villagers defined which of them are consumed for nutritional purposes; which of them are used in herby cheese consumed in the region widespreadly; which of them are used for medical purposes. As a result, the present paper presents new original plants used for drug industry on medical purposes (animal and human health).

  This study examined the responses to salt stress in 11 pea genotypes and two pea cultivars. Pea genotypes were selected from among wild pea and white flowered pea cross-breed varieties from different regions in Anatolia. In general, root fresh weight (fw) shoot fw, leaf fw, leaf number and chlorophyll contents were found to decrease with increases in salinity, whereas root and leaf MDA ratios increased with increases in salinity. Genotypes 1 (10431), 9 (101917) and 10 (1103220) were found to be the most salt-tolerant. Genotypes 6 (110121) and 7 (B-6) were found to be the most sensitive.

  The present study aimed to investigate the effect of different days (0, 7 and 15th days) and salt applications (salty and saltness) on nutrient element compositions of root, shoot and leaf organs of 11 field pea genotypes (which are nominate pea) and 2 pea cultivars. For this aim, the data were analyzed using three-way-ANOVA (genotypes, salt application and time). In this study determining, the effects of salt stress on nutrient element compositions of these organs, although the effects of salt application, salt by variety and salt by day interactions on Cu element in root were only found to be non-significant, genotypes, salt application, days and their interactions with 2 and 3 degree for other elements were found to be significant. In root and shoot organs, salt application increased significantly Ca, Mg and Zn amounts, but other minerals decreased compared to control group. The application in leaf increased Ca and Mg, whereas others reduced.

  The aim of this study was to compare their grass qualities by determining hay yields, crude protein ratios and yields of some sorghum and sorghum×sudan grass hybrid cultivars as second crop after barley in Erci -Van ecological condition in 2003. The experimental data were analyzed using randomized complete block design with 3 replications. In the present study, sorghum cultivars (Rox) and 7 sorghum×sudangrass hybrid cultivars (Grazer, Seweet Sioux, GW-9110, Sugar Leaf, Grass-II, 877 and GOzde-80) were used. For all cultivars, average of hay yield ranged from 9770-20550 kg ha 1. It was found in the present study that, cultivars with the highest hay yield were 877-cultivar (20550 kg ha 1) and Seweet Sioux cultivar, cultivars having the highest crude protein ratio were determined as Sugar Leaf (11.0%), Grazer (10.8%) and Sweet Sioux (10.5%), respectively. Cultivars with highest crude protein yield were determined as Sweet sioux (2140 kg ha 1) and Grazer (1750 kg ha 1). As a result, Sweet sioux and Grazer cultivars can be recommend to farmers in Erci -Van ecological conditions in terms of yield and quality, but 877-cultivar and Sweet Sioux sorghum×sudangrass hybrid cultivars can be suggested in terms of only yield.

  The present study was conducted to determine the effects of sulphur doses (5 doses), year and genotype factors on plant height, pod number, seed number, seed number per pod, biological yield, seed yield and 1000 seed weight on different field peas in experimental field of Yuzuncu Yil University during 2005-2006 years. For this aim, the data were analyzed using three-way ANOVA design (2 genotypes×2 years×5 sulphur doses×3 replications). The effects of genotype factor on pod number (p<0.05), seed yield (p<0.01) and biological yield (p<0.01) were found to be significant, whereas the influence of year on plant height, pod number, seed number and biological yield were significant (p<0.01). It has been suggested in present study that: The effects of genotype by year interaction on seed number and biological yield were significant, the effect of genotype by dose interaction on biological yield was found to be significant, the effects of dose by year interaction on seed number and biological yield were significant and the effects of genotype×year×dose interaction on seed number per pod, seed number and biological yield were found to be significant. As a result, it was concluded that genotype 2 in terms of pod number, seed number and biological yield was found to be more advantageous than genotype 1 as well as the highest seed yield and biological yield were obtained from 4th sulphur dose.

  The aim of this study carried out in Van Turkey in 1997 and 1998 was to determine the effects of different forms and doses of nitrogenous fertilizers on the safflower (Chartamus tinctorius cv. Dinçer 5-118) yield and yield components. The nitrogenous fertilizers (Ammonium sulphate (21% N), urea (45% N) and ammonium nitrate (33% N) and their four different doses (0, 40, 80, 120 kg ha-1) were examined in a Randomized Block Design with three replication. The plant height, the plant head number, the 1000 seed weight, the seed yield, the crude oil content and the crude oil yield were investigated. The nitrogenous fertilizer forms had a significant effects (p<0.01) on the seed yield in both years, but not on the crude oil content and the crude oil yield. The different nitrogenous fertilizer doses had a significant effects (p<0.05) on both the seed and the crude oil yields in  both years, but not on the crude oil content. While the highest seed yield  and crude oil yield (1994 kg seed ha-1 and 497 kg oil ha-1) were obtained from the application of the 120 kg N ha-1 ammonium nitrate, the application of the 80 kg N ha-1 urea gave the highest seed yield (1750 kg seed ha-1 and the application of 80 kg N ha -1 ammonium nitrate gave the highest crude oil yield (477 kg oil ha-1) in 1998. While the highest average seed and the crude oil yields (1597 and 422 kg ha-1, respectively) were obtained from the ammonium nitrate application, the 120 kg N ha-1 application dose gave the highest average seed and the crude oil yields (1685 and 437 kg ha-1, respectively).
