Key words: Electrical Conductivity, MSAR, Sodium Adsorption Ratio.

Abstract

Prediction of sodium adsorption ratio using available soil properties and simple empirical models have become particularly urgent to reduce the time and cost of some complex soil properties. The aim of this study is to estimate the sodium adsorption ratio (SAR) from soil electrical conductivity (EC), soluble calcium (Ca++) and magnesium (Mg++) to this end, a new equation was modified from soil SAR equation (MSAR).

Key words: electrical conductivity, irrigation treatments, plant density, seed vigour.

Abstract:

A field experiment was conducted in 2012 to investigate the effects of different irrigation treatments and plant density on seed vigour of Dragon’s head (Lallemantia iberica Fish. et Mey.). The experiment was arranged as split plot based on randomized complete block design with four replications.
