Effect of genotype x environment interaction was studied on relationship between yield and three yield components in 20 genotypes of chickpea. Significant differences were found between genotypes for the three yield components at all the locations. It was found that the pattern and strength of correlation between number of seeds pod and yield, between number of seeds pod and number of pods plan...

This research was carried out to evaluate the effect of drought stress on grain yield and qualitative traits in some Iranian landraces of confectionary sunflower. Fifty six confectionary sunflower landraces were evaluated using three different water treatment conditions with three separate rectangular 7 × 8 lattice design with two replications. Irrigation treatments were as follows optimum irri...

To evaluate the effect of different soil amendments on the yield and nutrient uptake of Salsola plant in the dry bed of Urmia Lake, an experiment was set up as a randomized complete block design with eight treatments and three replications in the 2013-2014 time period. These treatments included mycorrhiza usage, sand in the seed bed, plastic in the  depth of 70 cm, plastic in the  depth of 70 c...

In order to study the effect of terminal drought stress on yield and yield components and some physiological traits of wheat genotypes, a field experiment was conducted at the Research Farm of Agricultural College of Shiraz University during 2010-11 growing season in a split plot arrangement based on randomized complete block design with three replications. Main plots were assigned to irrigatio...

Potassium is one of nutritional element that has an important effect on the quantity and quality of rice plant. Knowledge about the K critical level and plant response to different application rate of K, can effectively help with the proper use of this element. Therefore, in this study potassium (K) critical level for rice (Khazar variety) and prediction equation for grain yield were determined...

Cadmium is a toxic element in plant nutrition and is considered as a contaminant of food and feed. A greenhouse experiment was carried out to examine the effects of combined application of cadmium and zinc on responses of wheat on a clay loam soil texture. This experiment was designed in a factorial experiment with randomized complete block design (RCBD) and four replicates per treatment. Three...

Identification of drought-resistant genotypes is crucial in order to reduce the negative effects of drought, as one of the most important limiting factors of crop production in arid and semiarid regions. Thus, effects of three irrigation regimes (irrigation after 50 (I1), 100 (I2) and 150 (I3) mm evaporation from a class A pan), as the main plot were investigated. These effects were studied on ...
