Effect of nitrogen (N) fertilizer levels and its split applications on yield and yield components of rice (Oryza sativa L.) Cv. Khazar was investigated in a completely randomized block design with 3 replications in a paddy light soil at Guilan province, Iran, 2003. In this experiment, six treatments including: T1-control (no N fertilizer) T2- 40 kg/ha N (at transplanting time) T3- 80 kg/ha N (a...
To evaluate the effect of airborne dust on some physiological characteristics and yield of different wheat varieties, a field experiment was conducted at Research Farm of Razi University, Kermanshah, Iran in 2013. The evaluated treatments were washing and un-washing shoots of various wheat varieties including Pishgam, Zarin and Behrang. Measured traits were as relative water content (RWC), SPAD...
This research was conducted at the research field of West-Azerbaijan (Saatloo station, 45° 10′ 53˝ E/ 37° 44′ 18˝ N and 1338 m above sea level), located 25 km from Urmia city (Iran) during 2019-2020 cropping seasons, as a factorial layout based on randomized complete block design with three replications. The first factor was irrigation regime at three levels (supplying 100, 75 and 50% of net ir...
This study was undertaken to identify morphological changes in young seedlings of 5 Iranian almond species (Prunus dulcis, P. eburnea, P. eleagnifolia, P. haussknechti, and P. scoparia) under polyethylene glycol-induced drought stress. Drought stress caused a significant reduction in plant growth parameters such as fresh and dry weights of plant organs, leaf number, total leaf area, and leaf re...
The effect of phosphorus (P) (0, 25, and 50 mg kg-1 soil as Ca(H2PO4)2) and organic matter (OM) (0, and 2% w/w feedlot cattle manure) on P and zinc (Zn) distribution in different parts of wheat plant (Triticum aestivum L.) at various growth stages and its relationship with soil P and Zn were determined in greenhouse condition. In all pots, shoot P concentration decreased as plant growth proceed...
A rice introgression line, NIL-SS1, and its recurrent parent, Teqing, were used to investigate the influence of the introgression segment on plant growth. The current research showed NIL-SS1 had an increased flag leaf width, total leaf area, spikelet number per panicle and grain yield, but a decreased photosynthetic rate. The metabolite differences in NIL-SS1 and Teqing at different development...
Development of superior crop varieties is the prime objectives of all plant breeding programs. To determine genetic variability, heritability and genetic advance, 24 elite bread wheat lines were planted in randomized complete block design with three replications at the University of Agriculture, Peshawar under rainfed conditions. Data were recorded on days to heading, days to maturity, plant he...
a study of physiological responses of different wheat cultivars to saline conditions can lead to an identification of the main mechanisms in salt tolerance. seven bread wheat cultivars differing in salt tolerance with varying ability of sodium accumulation in their different tissues were employed to assess ion distribution and sodium accumulation under saline conditions. ion distribution and na...
In order to study the effects of different irrigation regimes and different levels of salinity on the growth parameters of Quinoa (Chenopodium quinoa Willd.), this experiment was performed in the research green house of Water Engineering Department, at f Gorgan University of Agricultural Sciences and Natural Resources, during 2016. The experimental design was a factorial with n a randomized com...
seed production, as well as other economical and ecological attributes, is an important character in grasses. knowledge on the genetic diversity of seed yield and yield components on iranian tall fescue accessions, as a high productive and adaptive grass is limited. this experiment was conducted to investigate the genetic diversity of seed yield and seed components, determine relationships betw...
