Abstract

A field experiment was carried out in the Experimental Research Station at Nubaria, ARC representing newly reclaimed areas during two successive seasons of 2005/06 and 2006/07 to evaluate 16 barley (Hordeum vulgare L.) genotypes grown under water stress and calcareous soil conditions. The evaluation included yield and its components, growth attributes, earliness and kernel protein content. A randomized complete block design was used with three replications. Only two irrigations, i.e. at sowing and heading were applied to expose plants to water stress. Results showed that there are significant differences among the 16 barley genotypes for most of the characteristics. Four barley genotypes; Malouk//Aths/Linee686,Alanda-02/4/Arizona5908, Alanda/3/CI08887/CI05761//Lignee640, and Alanda/ Harma//Alanda01out yielded the check cultivars in grain and biological yield with some other advantages such as earliness, harvest index, leaf area index, and higher protein content. It is suggested that those genotypes could have more genetic stability studies to be grown in such calcareous soils. Kewwords: Hordeum vulgare, Leaf area index, Harvest index, Evaluation

Highlights

Barley (Hordeum vulgare L.) is the main crop grown in a large scale in the North Coastal Region of Egypt and in the newly reclaimed lands with saline soils and shortage of fresh water
The station is located at 47 Km South West of Alexandria city (30.540 N, 29.520 E) representing the newly reclaimed calcareous soils, which could be successfully cultivated by barley
The study was suggested to evaluate 16 barley (Hordeum vulgare L.) cultivars and genotypes grown under water stress condition at the calcareous soil of that region

Summary

Introduction

Barley (Hordeum vulgare L.) is the main crop grown in a large scale in the North Coastal Region of Egypt and in the newly reclaimed lands with saline soils and shortage of fresh water. It is mainly used for animal forages and recently it is used as human food because of its nutritional and healthy values in most countries using hull-less barley. Barley production area increased in the new reclaimed lands under different irrigation systems. Barley yields have tended to increase gradually over the past three decades from 2.92 t ha-1 in the eighties to 3.63 t ha-1 in 2008/09
