Effect of water stress and polymer (Superjazeb A200) on yield and water use efficiency of corn (Zea mays L.) in Birjand region

Fazeli Rostampoor, Mansour , Ph. D Student of Agronomy, University of Islamic Azad et al. [2011-08-23]

Drought stress is one of the most important problems of crop production in arid and semiarid regions of the world. The application of materials like superabsorbent polymers in soil could increase water retention in soil which results in reducing water use and fertilizer leaching. Such materials might decrease the impact of water deficiency on plants and improve the yield in the arid and semiar ...

Soil and water salinity are amongst the severe and progressive problems worldwide which affects most cropland areas of Iran. Using endophytic microorganisms (which are amongst the most important soil microorganisms) to alleviate the detrimental effect of environmental stresses such as salinity is recently globally considered. In order to test the effects of Azospirillum strains and fungus Piri ...

Evaluation of different salicylic acid levels on some growth characteristics of pot marigold (Calendula officinalis L.) under limited irrigation

Moradi Marjane, Elaheh , MSc Student of Agronomy, Ferdowsi University of Mashhad et al. [2011-08-23]

Water deficit is amongst the crop growth limiting factors and oxidative stress as a secondary stress occurs as a result of drought and water deficit. In order to study the effect of different salicylic acid levels in reducing water deficit impact on some growth characteristics of pot marigold plant, a factorial experiment was conducted based on CRD with three replications in Research Greenhous ...

Evaluation of yield and yield components of drought-resistant and susceptible cultivars of wheat under water stress conditions using FAO Penman-Monteith model

Hosseinpanahi, Farzad , PhD student of crop physiology, Ferdowsi University of Mashhad et al. [2011-08-23]

Studying the relationships between yield components gives an outstanding aid to understand the physiological basis of crop yield. A Field experiment was conducted to evaluate the yield and yield components of drought-tolerant and susceptible cultivars of wheat under drought stress, at the Ferdowsi University of Mashhad Research Field. Experiment was set up as a split plot design with 5 irrigat ...

Biosaline agriculture is one of the approaches to increase crop production under the existing situation of resources. Amongst halophytes, Kochia scoparia has been taken into consideration by researchers. Kochia is a mesohalophytes, C4 plant which has a good adaptability to different soil types. In order to evaluate the salinity effect on ion accumulation of kochia plant and its mechanism for s ...

Determining the optimal model for improving seed germination and seedling vigor of perennial grasses

Gazanchian, Ali , Department of Agronomy, Islamic Azad University, Bojnord branch [2011-08-23]

Success of seed germination and seedling establishment of perennial grasses, which are sensitive to environmental stresses, is of great importance in the renovation and amendment of pastures. To achieve this, seed priming technique was evaluated in improving germination rate and seedling vigor of five perennial cool season grasses including Bromus confinis, Elymus elongatum, Agropyron pectinif ...

Physiological responses of kallar grass (Leptochloa fesca L. kunth) to combined salinity and drought stresses under controlled conditions

Hajmohammadnia Ghalibaf, Kamal , . Lecturer of Faculty of Agriculture, Department of Agronomy and Plant Breeding, Ferdowsi University of Mashhad et al. [2012-02-20]

Drought and salinity are the most important limiting factors of plant growth and development in many regions of the world. Using plants that have satisfactory production under such conditions would be an appropriate strategy. To evaluate the combined effects of salinity and drought stresses on kallar grass (Leptochloa fusca L. kunth), a factorial experiment based on completely randomized desig ...

Evaluation of freezing tolerance of sweet william (Dianthus barbatus) under controlled conditions

Izadi Darbandi, Ebrahim , . Faculty members, Department of Agronomy and Plant Breeding, Ferdowsi University of Mashhad et al. [2012-02-20]

The aim of this experiment was to study the freezing tolerance of Dianthus barbatus under controlled conditions and was arranged as a completely randomized design with three replications. After sowing and growing plants in the bed in mid of summer to early autumn, at mid autumn (after hardening under natural conditions), plants were placed in the thermo-gradient freezer at the 7-8 leaf stage w ...
