To study yield and different traits and select the suitable apple cultivar for Golestan province, some vegetative traits and fruit quantitative and qualitative characteristics of five commercial apple cultivars Golden delicious, Red delicious, Braeburn, Red spur and Fuji grafted on MM106 were evaluated in Shahkoh during 2013-2015 using a completely randomized design with three replications and three trees in each replication. The highest yield efficiency was 0.49 kg per cm2 of trunk cross area in Red spur cultivar followed by Braeburn, Fuji, Golden delicious and Red delicious. Maximum firmness (5.74 kgcm-2) was in Fuji cultivar and minimum (4.82 kgcm-2) in Braeburn.The highest amount of total soluble solids and acidity were in Golden delicious cultivar (13.37 and 1.45, respectively). Results of simple correlation analysis indicated the existence of significant, positive or negative correlations between some characteristics such as fruit dimensions and skin thickness and cultivar. Based on the obtained results and due to short season growth period in shahkoh mountains, early to medium season ripening cultivars and semi-standard to standard rootstocks can be recommended for cultivation in this region.

To evaluate the effect of delayed sowing dates on phenological traits, yield components and seed yield of spring oilseed rape genotypes, a split plot experimental design with three replications was carried out at Mazandaran Agricultural and Natural Resources Research and Education Center during 2010-2011 and 2012-2013 cropping seasons. Four sowing dates of 19, 29 October, 8, 18 November were considered as the main plots and five genotypes of Zafar, Sarigol, L7, L4 and Hyola 401 as sub plots. The results of combined analysis of variance showed significant effects of sowing date, genotype and their interaction on all characteristics except 1000-seed weight. Delay in planting resulted in a significant reduction of seed yield and its components. Positive and significant correlation of seed yield with duration of flowering, days to maturity, number of pods per plant, number of seeds per pod, 1000-seed weight and harvest index showed that high levels of these traits in early sowing dates had increasing effects on seed yield. Among the genotypes, Zafar and Hayola 401 had high mean values of seed yield in all sowing dates and therefore had priority for planting in delayed sowing dates.

Current study was conducted to determine suitable plant density for new sunflower hybrids in second cropping. For this purpose, response of four new sunflower hybrids Barzegar, Ghasem, SHF81-90 and Farrokh to plant densities 8, 10, 12 and 14 plantm-2 was studied using factorial experiment based on randomized complete block design with four replications in Islamabade-e-Ghard Reseach Station during 2011 and 2012 cropping seasons. Results of two years variance analysis showed that plant density had significantly effect on all measured traits except harvest index. Four hybrids were also significantly different for all traits except seed number per head and harvest index. Interaction effect between plant density and hybrids was statistically significant only for 1000-seed weight. Seed yield was increased with increasing plant density, so that seed yield in 8, 10, 12 and 14 plantm-2 were 3555, 4043, 4550 and 5167 kgha-1, respectively. Among hybrids, Barzegar having more growth duration, had more seed yield (4638 kgha-1) compared to SHF81-90, Farokh and Ghasem with 4102, 4447, and 4128 kgha-1, respectively.

One of the main problems limiting almond culture is self-incompatibility and cross-incompatibility in pollination of different cultivars. In the present study, pollination compatibility of commercial and late flowering almond cultivar A200 with twenty almond cultivars and genotypes existing in the collection garden of Horticultural Sciences Research Institute, in Karaj was investigated. Fruit set was recorded three times after pollination. The growth of pollen tube in style was also studied 120 hours after pollination by fluorescence microscope (UV). The results of statistical analysis of the percentage of final fruit set showed that the best pollinizers for A200 were Shokofe, 24-14, 16-25, 14-12 and D99 genotypes with mean percentage fruit of 38.82, 37, 14.37, 36.14 and 32.58, respectively. The results of the microscopic study of pollen tube growth indicated that more than 75% of the pollen tubes of genotypes Shokofe, 14.24, 16.25, 14-12 and D99 in garden reached to the end of the style that was enough time. None of the pollinizer genotypes showed cross-incompatibility with A200. Thus, for development of new orchards of almond, all almond genotypes used in this study can be considered as pollinizer for cultivar A200..

To study the effects of wheat and canola residue management and tillage methods on maize yield and some soil properties, two separate experiments were carried out over three years (2009-2011) in Experimental Research Station of Orzoiyeh in Kerman, Iran. In each experiment randomized complete block design arranged in a split plot was used with four replications. Tillage methods (conventional and minimum tillage) were compared in the main plots and crop residue (residue rentention, residue removal and residue burning) were compared in the sub plots. In maize planted under canola bed, in conventional tillage, grain yield (14.4%) and plant height (7%) was more than minimum tillage. In maize planted under wheat bed, grain yield of maize was higher in conventinal tillage in the first and second years, but there was not any significant difference between two tillage methods in the third year. In comparison between wheat residue treatments, residues retention had the highest maize grain yield. The moisture content stored in the soil was highest in treatment of minimum tillage along with residue retention of wheat. In both experiments, residue rentention increased significantly soil organic matter and residue burning increased soil phosphorus and potassium. Grain protein of maize was higher in minimum tillage than conventional tillage, but crop residue management has not significant effect on grain protein content. Based on the results of this study, residue retention in soil can be recommended, but to determine minimum tillage positive effects in soil, long term experiments should carried out.

Aril color whitening or browning (AB) in pomegranate fruit is a physiological disorder that critically decrease fruit quality and market acceptability. To find the effects of cun screen, kaolin application, fruit thinning, supplementary irrigation and fertilizer on decreasing aril browning disorder of the pomegranate (Punica granatum L. cv. ‘Malase Torshe Saveh’), an experiment was carried out in Saveh using a complete randomized block design with three replications. Treatments were 1) 3% kaolin application at 40 days after full bloom (DAFB), 2) fruit thinning at 40 DAFB, 3) supplementary irrigation at 80 DAFB, 4) fruit thinning with kaolin application, 5) supplementary irrigation combination with fruit thinning and kaolin application, 6) control with conventional management, 7) Animal manure application with foliar spray of the potassium sulfate and Nitrate calcium, 8) sunscreen combination with kaolin application and supplementary irrigation. The experiment was carried out in 2014 and 2015 in a commercial pomegranate orchard, in Saveh, Iran. The physicochemical properties of the pomegranate fruits were measured. Results showed that the kaolin application had no significant effect on the aril browning disorder, but the sunscreen treatment combined with supplementary irrigation and kaolin application reduced the aril browning index (24%) and increased the abundance of non-affected fruit (%96), conversely the fruit thinning increased aril browning index (69%) and reduced the abundance of non-affected fruits. Moreover, the supplementary irrigation had positive effect toameliorate the aril browning disorder, but the aril browning was also influenced by high temperature, low relative humidity and water quality. Overhead sunscreen, increase soil organic matter, foliar application of potassium and calcium during the growing season and irrigation with fewer intervals can ameliorate the pomegranate aril browning disorder and improve the fruit quality.

Drought stress in sesame happens regularly during September in Behbahan region. This research was carried out in two separate experiments based on randomized complete block design with three replications at Behbahan Agricultural Research Station for two years (2012 and 2013). In the first experiment irrigation was after 100mm (usual irrigation) and in the second experiment after 200mm evaporation from class A pan (stress). Genotypes were L5-84215, L5-86365 and Safiabadi lines, Yellow White cultivar and Behbahan local population (check). Combined variance analysis results showed that in both experiments the effect of genotype was significant at 1% probability level on pod number per plant, 1000 seed weight and seed yield. In the first experiment (usual irrigation) the heightest seed yield was produced by Behbahan local population (1286 kgha-1). In the second experiment (stress) the heightest seed yield was produced by Behbahan local population (741 kgha-1). L5-86365 line had the lowest stress susceptibility index (0.92). Safiabadi line had the lowest tolerance index (272.93). Behbahan local population had the heightest stress tolerance index (0.99), mean productivity (1013.52) and geometric mean productivity (976.24). Behbahan local population had the heightest water productivity (0.26 kgm-3 in the first year and 0.23 kgm-3 in the second year). Due to the higher seed yield in normal and stress conditions, favorable amounts of drought tolerance indices and water use efficiency of sesame Behbahan local population, this population can be recommended for cultivation in Behbahan regions.
