Allelopathic effect of some tree fruits on wheat (Triticum Aestivum L.)
An experiment was conducted to determine the allelopathic potentials of fruits of different plant species on the germination of wan heat variety Pir Sabaq 2005. The experiment was laid out in completely randomized design (CRD) with three treatments and four replications. The aqueous solution of fruits of three plant species including Eucalyptus camaldulensi, Melia azedarach […]
Propagation protocol of Pteris vittata L. using spores for phytoremediation
Pteris vittata has been reported to be a hyperaccumulator of arsenic, and therefore useful in phytoremediation to clean-up arsenic-contaminated soils. Although factors for successful germination of spores have been identified, but information concerning the whole range of steps involved in mass propagating the fern is lacking. Thus, the study was aimed to develop a propagation […]
Tetraploid monogerm lines as maternal components of sugar beet hybrids
Tetraploid monogerm lines of sugar beet with pollen sterility and their hybrid combinations with diploid multigerm pollinators are the object of the present study. Data received for the sterility of the lines and the percentage of the hybrids in their progeny confirm the thesis, that almost a full hybridization is obtained in this type of […]
Qualities of monogerm male-sterile sugar beet lines
The majority of the commercial varieties of sugar beet in Europe are hybrids, based on monogerm diploid male-sterile females and multigerm diploid and tetraploid pollinators. The aim of the present study is by testing the basic biological qualities of recently created male-sterile sugar beet lines (male sterility, monogermity, seeds germination), and the combination of productivity […]
Evaluation of Maize Genotypes for Some Quantitative Traits in the Agro-Climatic Conditions of Swat Valley
The present study was carried out at Agriculture Research Institute (North) Mingora (ARI-N) Swat, Khyber Pakhtunkhwa for the evaluation of 20 maize genotypes for ten quantitative traits in the agro-climatic conditions of Swat valley with the aim to reveal information on the nature and degree of genetic variability, the pattern of association between yield and […]
Response of black cumin (Nigella sativa L.) to different levels of Ece and SAR
Salinity is a wide spread environmental stress that reduces the agricultural productivity of arid and semi-aridareas of the world. A three years pot trial was performed to study the tolerance of pharmaceutical plant i.e. black cumin (Nigella sativa L.) towards combined effect of electrical conductivity (ECe) and sodium adsorption ratio (SAR)at its germination, vegetative growth […]
Morpho-physiological characterization of cultivated rice (Oryza spp.) during early vegetative growth under different soil water conditions
In rainfed rice cultivation, weeds, low or no fertiliser inputs and no water control can be production constraints. Vegetative early vigor may favour weed competitiveness. Since Oryza glaberrima is considered as genetic resources for this characteristic, growth analyses of three lines were made from seeds to juvenile plants of 35 days after seed soaking (DAS) […]
Role of new novel entomopathogenic fungi Paecilomyces lilacinus to mortality and infection process of Tetrancyhus kanzawai (Kishida) (Tetranychidae: Acarina)
P. lilacinus is a common soil hyphomycete with a cosmopolitan distribution. Since Its characteristic has similarity with Metarhizium and Beauveria, it is assumed that it can be effective as well Metarhizium and Beauveria . The experiment was conducted in the Green house with papaya plant. The papaya seedlings were hand-sprayed with suspension with a density […]
Effect of fly ash on growth and yield of sunflower (Helianthus annuus L.)
Fly ash, the notorious waste product of coal based thermal power plants, rich in micro and macronutrients and has the potential to improve the physical and chemical properties of soil. With this concept, a field experiment was carried out to find out the efficacy of the fly ash for agriculture. Fly ash from NALCO CPP, […]
The effect of environmental characteristics and metabolism in response to water stress in three Festuca species
In order to determine the reaction of three Festuca species to drought stress, two separate experiment were conducted in both germinator and greenhouse conditions using factorial experiment based of completely randomized design with three replications in 2010 in Tehran, Iran. The drought treatments were four levels of osmotic potential (0, -0.3, -0.6 and -0.9 MPa) […]
