Abstract:

This research was conducted to study and classify the physico-chemicalproperties of soil, yield components of wheat and to determine the significance ofthese parameters on the grain yield formation. In this research, seven statisticalmethods consisting of simple correlation analysis (SCA), multiple linear regression(MLR), stepwise regression (SR), factor analysis (FA), principal componentanalysis (PCA), cluster analysis (CA) and path analysis (PA) have beeninvestigated. The physico-chemical properties of soil, different morphological traitsand wheat yield have been obtained from a field with 250×300 meter dimensionlocated in Bajgah (with silty clay loam soil) that consisted of 30 samples. Amongstatistical analysis performed, MLR has provided more acceptable results. In thismethod, among the examined characteristics, five traits i.e., the number of stemswithout spikes per plant, biological yield, harvest index, soil soluble potassium andsoil available phosphorus, examined 98.3% of the variations of the yield (P

Chemical Composition, Yield and Yield Components of Two Wheat Cultivars in Response to Salt Stress

  Abstract In most southern provinces of Iran, soil salinity is a growing problem, particularly in irrigated agricultural areas, and has been found to reduce wheat yield, dramatically. To investigate the effect of sodium chloride on two wheat (Triticum aestivum L.) cultivars, four levels of salinity: 0, 4, 8 and 12 dS/m, were employed as a factorial experiment arranged in a randomized complet...
