SILICON MANAGEMENT AND SUSTAINABLE WHEAT PROUDUCTION UNDER RAIN – FED SOIL

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...

Soil loss and runoff generation in rangeland, rain-fed and abandoned rain-fed agriculture land-uses under simulated rainfall

Soil erosion is a global challenge, seriously threatening soil and water resources andenvironmental qualities. One of the important factors to consider in the process of runoffgeneration and soil erosion is the physical and chemical properties of soils under differentland-uses. The aim of this study is to estimate soil erosion and runoff in rangeland, rain-fedand abandoned rain-fed agriculture ...

Weed flora and their effect on rain-fed wheat in fars province iran

Comparison of physiological and biochemical responses of wheat and barley to Selenium by spraying application under rain fed conditions. Nour Ali Sajedi* and Hamid Madani

This study investigated the effect of two forms of Se at three rates (0, 18, and 36 g/ha) on wheat and barley under rain fed conditions. Results showed that spraying application of 18 g/ha Se increased Chl a and Chl a+b contents while the selenium rate 36 g/ha decreased plant pigments. Evaluations of Chl a, Chl b, chlorophyll total a+b, carotenoids, chlorophyll total content, relative water con...

Effect of silicon supplementation on wheat plants under salt stress

Heavy metals are the cause of major abiotic stresses in plants and a principal contributor to environmental pollution in recent decades. This study investigated the effects of exogenous hydrogen sulfide on the ascorbate-glutathione cycle in the leaves of coriander seedlings under copper stress. Results showed that copper stress not only reduced APX and GR activities but also decreased leaf AsA,...
