Effect of Different Sulphur Doses on Yield and Yield Components at Field Pea (Pisum Sativum Sp. Arvense L.) Genotypes
(Medwell online, 2008) Yildirim, Buenyamin; Erman, Murat; Tuerkoezue, Didem
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 genotypesx2 yearsx5 sulphur dosesx3 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 oil 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 genotypexyearxdose interaction oil 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 I as well as the highest seed yield and biological yield were obtained from 4th sulphur dose.
Quality Characteristics of Sorghum (Sorghum Bicolor (L.) Moench)and Sorghumxsudan Grass Hybrids (Sorghum Bicolor (L.) Moenchxsorghum Sudanense Stapf.) Cultivated as Second Crop After Barley in Ercis-Van Ecological Condition
(Medwell online, 2008) Terzioglu, Oemer; Yazici, Levent; Yildirim, Buenyamin
The aim of this study was to compare their grass qualities by determining hay yields, crude protein ratios and yields of some sorghum and sorghumxsudan grass hybrid cultivars as second crop after barley in Ercis-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 sorghumxsudangrass 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 Ercis-Van ecological conditions in terms of yield and quality, but 877-cultivar and Sweet Sioux sorghumxsudangrass hybrid cultivars can be suggested in terms of only yield.
Variations in Response To Salt Stress Among Field Pea Genotypes (Pisum Sativum Sp.arvense L.)
(Medwell online, 2008) Yildirim, Buenyamin; Yasar, Fikret; Ozpay, Taylan; Turkozu, Didem; Terziodlu, Omer; Tamkoc, Ahmet
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.
Yield Characteristics of Sorghum (Sorghum Bicolor (L.) Moench) and Sorghum X Sudan Grass Hybrids (Sorghum Bicolor (L.) Moench X Sorghum Sudanense Stapf.) Cultivated as Second Crop After Barley in Ercis-Van Ecological Condition
(Medwell online, 2008) Terzogll, Oemer; Yazici, Levent; Yildirim, Buenyamin
This Study was conducted to find out the possibilities of growing sonic sorghum and sorghum x sudangrass hybrid cultivars as second crop after barley in Ercis-Van ecological condition in 2003. The experiment was designed as randomized complete block design with three replications. In the experiment, one sorghum cultivars (Rox) and seven sorghum x sudangrass hybrid cultivars (Grazer, Seweet Sioux, GW-9110, Sugar Leaf, Grass-II, 877 and Gozde-80) were used. Significant differences were determined among the cultivars used in the research. Avarege green herbage, herbage yields changed between 42000-82000 kg ha(-1), hay yield 9770-20 550 kg ha(-1), respectively. The highest herbage yield was obtained from seweet Sioux (82 000 kg ha(-1)), followed by 877-cultivar (74 000 kg ha(-1)). According to this results, Seweet Sioux and 877 sorghum x sudangrass hybrid cultivars had the highest green herbage and hay yield, therefore this cultivars are suggested as second crop in Ercis-Van ecological condition.
