        This resarch was conduted to evaluate seed yield and yield components of 20 barley lines at Agricultural and Natural Resources Resarch Center of Tabriz, Iran uing a randomized complete block design (RCBD) with three replications. Analysis of variance showed that there were sigificant differece among lines under study for plant height, thousand kernel weight, number of grains per spike, grain yield, spike weight spikes per square meter and spike length. This shows that there gentic was variations for these traits among the lines studied. Mean comparisions of the traits showed that line EBYTC86-17 by having higher spike length, kernel per spike and 1000 kernel weight produced highest yield. This line can thus be regarded as suitable far thurther studies and recommend at to this area. It was also revealed that lines EBYTC86-5, EBYTC86-6 and EBYTC86-13 were low producers. Results of simple correlation coefficients among the traits showed that yield and yield components were highly correlated with kernel weight and kernels number per spike. Based on regression analysis, 37 percent of yield variation can be attributed to seed number per spike and 1000 kernel weight. Results also showed that for each unit increase in 1000 kernel weight and seed number per spike yield increased by 30 and 14 percent respectively. However, each unit increase in plant height decreased seed yield by percent. Manuscript profile

        To study the effects of sowing dates on seed yield its components and oil content of three spring safflower varieties a factorial experiment based on randomized complete block design with three replications was conducted during the spring of 2009 at Agricultural Research Station, Agriculture Faculty Islamic Azad University, Tabriz branch, Iran. Treatments in this study consisted of four sowing date (26April, 2 May, 8 May, 14 May) and three safflower varieties (Mex33, Isfahan, Goldasht). Analysis of variance showed that late planting(26April) reduced seed yield and oil yield, seed number per head, head number per plant, 1000 kernel weight, planting height, number of leaf, shoot dry weight and oil content of seed. Analysis of variance also revealed that interaction effects of planting date by genotype was significant for height plant. The highest seed yield was observed in the first planting date (2267 kg/ha) and the lowest seed yield at the fourth sowing date (1124 kg/ha). The highest head number per plant was obtained at first planting date (13.44) and the lowest was at the fourth sowing date (6.77).The highest seed number per head was obtained at first planting date (57.78) and the lowest at the forth sowing date (36). The highest 1000 kernel weight at first planting date (37.78gr)and lowest 1000 kernel weight at the fourth sowing date (26.33g).It was also observed that the highest stem height belonged to Isfahan (87.50 cm) at the first planting date and lowest to Goldasht (55.90 cm) at the fourth planting date. The highest oil yield was obtained from first planting date (782.60 kg/ha) and lowest from fourth sowing date (292 kg/ha). However, the effect of sowing date on oil percentages was non significant.

        3 - The Study of Some Morphophysiological Characteristics Associated with Seed Yield and its Components of Rapeseed

        To investigate association of some morphophysiological characteristics with seed yield and its components of oilseed rape varieties, a research was carried out at East Azerbaijan Agriculture and Natural Resources Research Center in 2005-2006. Experimental design was randomized complete block with four replications. Varieties under study showed significant differences in leaf area and leaf number per plant (typeI, II and total), leaf dry weight per plant, specific leaf weight, leaf temperature, seed oil percent, seed and oil yields. The results indicated that high yielding varieties possessed higher levels of leaf area (type II). SLMO46, Sunday, ARC-2, Opera and Ebonite had the higher seed yields than other varieties respectively. Sunday, Ebonit, SLM046, ARC-2 and Opera produced higher and Okapi, Sinatra, Regent×Cob, Geronima and Olpro lower oil yields. In this research, a positive and significant correlations were observed between seed yield with oil yield, leaf area type II, total leaf area, leaf dry weight, while a negative and significant correlation between seed oil and seed yield were seen. Correlations of oil yield with seed oil, seed yield, leaf dry weight and leaf area (typeI, II and total) were positive and significant. It seems that leaf area, especially larger leaves with longer petiole (type II), had important role in seed and oil yields. It can be concluded that replicating the experiment, would possibly result in recommending adaptable and high yielding oilseed rape varieties for cold climates of the country. Manuscript profile

        To determine the effects of foliar applications of some macroelements on castor seed yield and its components under drought stress conditions, an experiment was conducted at the Agricultural Research Center of East Azerbaijan province. A factorial experiment, based on randomized complete block design with three replications, was carried out during 2013 growing season. Treatment factors consisted of irrigations with two levels (no water deficit and water deficit during grain filling stage) and of foliar applications of macroelements with four levels [control, wettable sulfur (0.2 percent), nitrogen (urea: 0.6 percent) and phosphor (super phosphate triple: 0.4 percent). Traits studied were: plant height, number of inflorescence, number of lateral branches, number of leaves, leaf temperature, relative water content, number of seeds per plant, 1000-kernal weight and seed yield. All traits, except number of inflorescence, were affected significantly by drought stress. Water deficit reduced plant height, number of leaves, number of seeds per plant, 1000-kernal weight, seed yield, relative water content, while it increased leaf temperature. Number of lateral branches was affected significantly by interaction between factors. Maximum latral branches (1.86) were obtained under non-stress treatment with nitrogen foliar application. Moderate drought stress had significant effect on leaf temperature and relative water content. It seems that, these traits can be used in determination of water deficit effects on castor bean.
