to estimate the optimum and effective amount of nitrogen fertilizer for quantity and quality improvement of three new durum wheat lines, this research was conducted in gachsaran dry-land agricultural research station for a duration of 4 years (2003-2007). the study was performed as a factorial expriment, using a randomized complete block design with 4 replications. two factors of: 4 nitrogen ra...

The effect of flooding can be a serious problem for wheat farmers, even at dry land condition. Amount of flooding damage depends on duration flooding, developmental stage, wheat type and variety. Therefore as a factorial experiment in randomized complete design based on winter bread wheat cultivars (Pishtaz, Marvdasht, Shiraz, Zarin, Shahriar, C-81-4, Sardari, Agosta seed, FGS and Azar2) at sta...

Low zinc (Zn) availability and its absorption limit wheat production and quality of yield in calcareous soils. In order to identify Zn deficient stress tolerance in wheat, fifteen spring genotypes (Diyarbakir-81; Gediz-75; Svevo; Zenit; Amanos-97; Fuatbey-2000; Balcali-2000; Ceylan-95; Firat-93; Aydin-93; Ozbek; Artuklu; Akcakale-2000; Aday-19; and Ege-88) were evaluated under two conditions (n...

The present investigation was conducted using 102 wheat genotypes at Research Farm, College of Agriculture, Gwalior during Rabi 2018-2019 in randomized block design with two replications. A set genotype were used to estimate genetic variability, correlation coefficients and path for fourteen yield its accrediting attributes. wide range variation observed important components. GCV PCV recorded h...

to determine the correlation between important traits with yield in barley through path analysis for selecting high yielding lines, three new lines of barley resistant to cold (c-81-13, c-81-11, c-81 -15), compared with valfajr (as control) were studied. this experiment was conducted in a randomized complete block design with three replications, during 2008 to 2010 in boyer ahmad city.a number ...

studies on manipulating the source-sink relationships during postanthesis in wheat have shown inconsistent results, concluding that wheat yield could be either sink- or source-limited. most studies have reported data of grain mass as an average of all grains preventing the recognition of different sensitivities to the availability of assimilates of grains placed at different positions within th...

Abstract Cyanobacteria like Arthrospira platensis and Nostoc muscorum are known to be beneficial for plant development. They can improve growth, yield, proximate content (protein carbohydrate), stimulate tolerance abiotic stresses herbicides. In the present study, impacts of brominal herbicide (Bh) alone or in combination with natural cyanobacterial synthetic tryptophan treatments were investig...
