Effect of Different Sulphur Doses on Yield and Yield Components at Field Pea (Pisum sativum sp. arvense L.) Genotypes

摘要

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.
