Relationships between wheat yield, yield components and physico-chemical properties of soil under rain-fed conditions
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 componentanalys...
متن کاملEffect of Some Soil Properties on Distribution of Eurotia ceratoides and Stipa barbata in Baghedar, Bafgh Rangelands
In order to sustainable use of rangelands, it is necessary to recognize water, soil, and vegetation cover and analyze their relationships. Physical and chemical properties of soil are effective in distribution of plant species in local area. To determine the effects of some soil properties on species distribution of Eurotia ceratoides and Stipa barbata in Baghedar summer region of Bafgh, three ...
متن کاملEffect of Different Tillage Systems on Soil Physical Properties and Yield of Wheat (Case Study: Agricultural Lands of Hakim Abad Village, Chenaran Township, Khorasan Razavi Province)
This research delves into investigating the effects of different soil management practices on soil physical properties, yield and yield’s components of irrigated wheat. This experimental design was administered in the form of the nested testing with three treatments (no tillage, low tillage and conventional tillage) and three replicates in some of the farmlands of Chenran Township. The results ...

متن کاملRelationships between Soil Properties and Plant Species Diversity in Natural and Disturbed Ecosystems (Case Study: Jamilabad Region, Kerman Province, Iran)
Reduction of species diversity which is a significant threat to the earth has been found more important and has attracted attention among ecologists over recent years. This research was carried out to determine the relationships between plant species diversity indices and soil properties by multivariate regression methods in Jamilabad region, Baft, Kerman province, Iran in 2016. Different sites...
متن کاملبررسی قابلیت استفاده از نقشۀ واحدهای خاک بهمنظور برآورد تغییرات مکانی فاکتور فرسایشپذیری خاک
Soil erodibility is one of the six components affecting water erosion of the universal soil loss equation (USLE). K-factor ‎is best obtained from direct measurements on natural plots. This is an infeasible task on large scales. To overcome this ‎problem measured K-factor values have been related to soil properties and the soil classification maps are used. The ‎current research exam...
