MORPH PHYSIOLOGICAL TRAITS OF SAFFLOWER AS AFFECTED BY PLANT DENSITIES AND NITROGEN FERTILIZATION

Seed yield and some physiological traits of safflower as affected by water deficit stress

Safflower (Carthamustinctorius L.) is an oilseed crop adapted to drought prone arid and semi-arid environments. This study was conducted to evaluate the effects of water deficit stress on antioxidant activity, membrane stability index (MSI), leaf chlorophyll content, leaf area index (LAI) and their relationship with seed yield using 64 safflower genotypes grown under normal and water defici...

Biomass Accumulation, Photosynthetic Traits and Root Development of Cotton as Affected by Irrigation and Nitrogen-Fertilization

Limitations of soil water and nitrogen (N) are factors which cause a substantial reduction in cotton (Gossypium hirsutum L.) yield, especially in an arid environment. Suitable management decisions like irrigation method and nitrogen fertilization are the key yield improvement technologies in cotton production systems. Therefore, we hypothesized that optimal water-N supply can increase cotton pl...

salinity tolerance of kentucky bluegrass as affected by nitrogen fertilization

in most semiarid and arid areas, fresh water shortage compels managers to use low quality water sources with high salinity to irrigate turf and landscape. recent research has noticed that management of nitrogen fertilization can alleviate salinity effects on plants. this greenhouse sand culture experiment was conducted in order to investigate morphological and physiological responses to salinit...

Sunflower summer-planting yield as affected by plant population and nitrogen application rates

Evaluation of Quantitative and Qualitative Traits of Chickpea as Affected by Biofertilizer, Nitrogen, and Humic Acid in Dryland Condition

In order to evaluate biofertilizer, nitrogen and humic acid effect on quantitative and qualitative traits of chickpea (ILC 482 line) this research was carried out at the Agricultural Research Field of Kurdistan University, Sannadaj, Iran. A factorial experiment was conducted based on a randomized complete block design with three replications. Experimental treatments included three levels of lea...
