Peas are the second most important plant families with high quality protein and important role in increasing soil nitrogen. The plant is sensitive to salinity and given that a large part of our land and the passion necessary to make possible the necessary measures to be taken to prevent a decrease in performance. In this regard, one of the elements that can improve plant water status, the effects of salinity amend, is silicon. For this purpose, a factorial experiment in a completely randomized design with three replications was conducted. Treatments consisted of soil salinity at levels 2, 4 and 6 dS/m and sodium with levels of 0, 1 and 2 mM. The results showed that salinity had a significant effect on the number of pods per square meter, number of seeds per square meter, grain weight, grain yield and dry matter, so that increasing salinity level would be to reduce the amount of these traits. The yield on the EC 6 dS.m to the 41.4 grams per square meter, respectively. Silicon is also a significant effect on the number of pods per square meter, seed weight and seed yield. The highest grain yield in 2 mM sodium consumption to the amount of 99.7 grams per square meter.   Manuscript profile

In order to evaluate the effect of irrigation and pattern of nitrogen topdressing on yield and yield components of sunflower, an experiment was carried out in complete block design with split-plot arrangement in three replications during 2012 growing season.  Irrigation regimes were allotted to main plots and nitrogen treatments were allotted to sub-plots. Irrigation regimes were consisted of: 1) moderate irrigation 2) water stress at V8 growth stage and 3) water stress at heading stage. The nitrogen treatments were consisted of: N1: 25% at sowing, 50% at V8, 25% at heading; N2: 50% at V8, 50% at heading; N3:50% sowing, 50% heading; the results showed that water stress at heading significantly decreased the head diameter and100-grains weight and non-significantly decreased the grains per head which was resulted to 15% lower grain yield comparing to the moderate irrigation. Under moderate irrigation, N3 treatment non-significantly increased the head diameter and biomass comparing to the N2 treatment by 9 and 16% respectively. Under water stress at V8, N3 treatment significantly increased the head diameter and biomass comparing to the N1 treatment by 12 and 29%, respectively. This result showed that choosing a suitable pattern of nitrogen top-dressing for attaining the maximum grain yield is more important when the plants are not suffering water stress or stress is occurred at early vegetative stage. But when the stress is occurred at early vegetative stage, then the pattern of nitrogen topdressing is not such important.   Manuscript profile

In order to study the effects of seed priming with ascorbic acid (AsA) on agronomic traits of two soybean cultivars under normal irrigation and interrupted irrigation at flowering stage, this experiment was carried out in a split-plot factorial arrangement with randomized complete block design in three replications at the research farm of agriculture faculty, Islamic Azad University, Sanandaj Branch in 2013. The main factor was irrigation with two levels of full irrigation and interrupted irrigation at flowering stage. The factorial combination of cultivar and seed priming with AsA was assigned in sub-plots. Two soybean cultivars included Hobbit and L17 and seed priming treatments included: 0 (Control or non-priming), 50, 100 and 150 mg/L AsA. Results showed that two soybean cultivars differently responded to seed priming with AsA under full irrigation and interrupted irrigation (drought stress). Hobbit cultivar positively responded to priming under stress conditions. AsA application in seed priming resulted in increasing of seed yield and seed oil yield in comparison with control (non-priming), whereas L17 cultivar had no response to seed priming in stress conditions. On the other hand in normal irrigation conditions two cultivars showed a reverse reaction to seed priming so that L17 cultivar positively responded to priming under full irrigation conditions especially the concentration of 150 mg/L AsA expressively increased seed yield of this cultivar Manuscript profile

Understanding of the factors importing quantity and quality of saffron plant to obtain desirable performance is important. Among these factors is use of different fertilized and corm densities. To study the effect of corm density and urea fertilizer as well as bio fertilizer nitroxin on the performance, vegetative organ, and photosynthetic pigments of saffron plant, a research was conducted in randomized complete blocks design in a field located in Davoodabad, Gharchak. Treatments included three levels of corm densities (60, 120, 180corm per m2) and four levels of fertilizers: control, urea fertilizer (150kg.ha) nitroxin bio fertilizer (5 L.ha) as well as urea nitroxin (75 kg.ha) and nitroxin (2.5 L.h). The results showed that all treatment had significant effects on all traits at 1% cultivation of high density of saffron corms (180m2) had cumulative positive effect on all traits but leaf length. It should be noted that the interactive effect of fertilizers and corm density on most of traits was significant. The maximum number of flowers per corm planting density of 180 per square meter and fertilizer use Nitroxin with the 64.97 and the least number of flowers per corm density of 60 per square meter and not using fertilizer with an average of 3.30 goals per square meter, respectively. The highest and lowest of 2.93 and 0.74 respectively kilograms of yield per hectare were achieved in treatments D3F3 and D1F1. Manuscript profile
