In order to explore the possibility of enhancing wheat productivity with limited inputs, an experiment entitled “Effect of seed soaking in nitrogen, phosphorus and herbicides solutions on yield and other characteristics of wheat” was conducted at the Agriculture Research Farm of NWFP Agricultural University Peshawar during winter2002-03. Seeds were soaked in pure water, 0.1% and 0.5% urea solut...

Frequent and intense defoliation of grasses has been associated with the evolution of “grazing morphotypes” that exhibit a variety of vegetative traits correlated with improved grazing resistance. While recovery from a seed bank is not considered an important grazing resistance mechanism, relatively little is actually known regarding seed (caryopsis) production in grazing morphotypes of caespit...

Identifying selection indices is the most important step of a breeding project that aims to improve grain yield. The definition of the selection index is usually done by evaluating the variables in multivariate statistical methods. In the present study, the relationship between grain yield and its components in bread wheat genotypes was determined by multivariate statistical methods. The experi...

Cadmium as an environmental pollutant heavy metals have effect on morphological and physiological activities in plants. Selenium, an essential element had beneficial effects on enhanced tolerance in plants against environmental stresses. In the investigation, from Cadmium chloride concentrations 0, 350, 700 µM supplied with added to soil and Sodium selenat 0, 1.5, 3 mg L-1 as a foliar applicati...

     Triticum boeoticum wild wheat is a remarkable gene pool to environmental stress resistance. It is one of the most valuable species of the Triticeae tribe for improving wheat cultivars to moisture-stress. This research was carried out to assess the changes and responses of different traits of 10 accessions of Triticum boeoticum under non-stress and imposed moisture stress conditions in 2015...
