Selection and introduction of superior genotypes from native populations is one of the most common improving methods for fruit trees in the world. Iran as a very important origin of apricot has a huge diversity of varieties, so a rich collection of local and imported genotypes of apricot was induced in Sahand Horticultural Research Station from 1971. Nasiri 90 and other four superior varieties were evaluated as a ten years old project in three different areas of East Azerbaijan province. In addition to all vegetative and productive traits, some important tests such as evaluation of chill and heat requirement, determination of incompatibility and pollinizer, xenia and metaxenia, drying and processing, determining of suitable harvest time and packaging method were studied during these years. Results showed that Nasiri 90 had high yield (above 10 t/h), big fruit size, high flesh thickness, and high fruit sugar, so is suitable for drying. Its chill and heat requirements are 825 C.U and 3350 G.D.H respectively. Also because of its incompatibility and metaxenia, it is better to use from Aybatan and Maragheii90 apricots as pollinizer. Suitable harvest time of this variety was 81 days after full bloom synchronous with 27750 growth degree hour. Vegetative and fruit quality traits of this variety had a good stability in different area and years but its bearing and yield were depended on different climatic conditions.

Irrigated barley is grown on about 50,000 hectares in the warm agro-climate zone in the south of Iran. The average grain yield of barley in these areas is 2,000 Kg/ha. Wide adaptability and high grain yield stability are important assets for barley varieties to be grown by farmers. Zahak barley cultivar was initially selected from international barley germplasm received from CYMMIT and based on its high grain yield and yield stability as well as its desirable agronomic characteristics in the experiments, which were conducted from 1996 to 2010, was released for growing in the warm agro-climate zone in the south of Iran. The average grain yield of Zahak is 4846 kg/ha that is 524 kg/ha higher than grain yield recorded for Nimrooz variety, a widely-grown barley variety in the warm regions of Iran. Zahak is six-rowed spring barley with a medium plant height (85-90 cm). The average of days from sowing to maturity for Zahak is 138 days but it has a longer grain filling period comparing to the older barley cultivars in southern parts of Iran such as Jonoob and Nimrooz. Possessing fertile florets at the lower spikelets of the mature spike is other important characteristic of Zahak. In addition, it exhibits lodging resistance, non-shattering rachis as well as semi-resistant infection responses to powdery mildew and spot blotch diseases in the most of warm agro-climate zone in the south of Iran.

Leopard moth, Zeuzera pyrina L., is a xylophagous key pest in Iran. Pest has major hosts in orchards. Walnut is the main host in orchard trees. Other hosts in Iran are apple, pear and Quince. At present, this pest is active in the middle and eastern provinces of Iran. In this study, the efficacy of a new and common method which is mass trapping of male insects by synthetic pheromones was investigated. The test was conducted in a completely randomized block design with 5 treatments and 5 replications. The treatments included control, 4, 8, 12 and 16 pheromone traps/ha. The pheromone of clearwing moth, Synanthedon tipuliformis was used in this study. To install of pheromone traps in orchards, we used delta traps. We carried out this project in two years (1389-90) in two years (1389-1390) obtained in Horticultural Research Station in Kamal shahr, Karaj, indicated that in first and second years treatments can be placed in 5 and 3 statically groups, respectively. Evaluation of experimental treatments done on the base of number of first instars larvae penetrated in to non-woody branches. According to that in first year application of 16 traps with means of 1.84± 0.133 and in second year application of 4 traps with mean of 0.66±0.169 penetration showed the best results. Based on these results, orchards are recommended to do this 2- year's procedure in order to effectively reduce the damage.

The objective of these investigation were use of berseem clover (Trifolium alexandrinum ) in double cropping system (after autumns crop) to improve forage production in Shahrekord region. The experiments were carried out in the preliminary, research and farmer field condition in 2005, 2006-7 and 2013 respectively. In 2005 the results showed that there is possibility of double cropping of berseem clover after canola and one cut dry forage was harvested with 3343 kg ha-1. In 2006-7 results revealed that the most dry forage yield of berseem clover in double cropping after canola was obtained from 6 and 16 July planting (with 25.7ºC and 24.4ºC daily average temperature respectively) and use of 25 to 30 kg ha-1 seed rates (upper 4000 kg ha-1 dry forage) in research field condition. In 2013 results showed that there is possibility of double cropping of berseem clover after barely in farmer field condition and one cut dry forage was harvested with 2750 kg ha-1 and 20.7% protein. In generally the results represented that double cropping of berseem clover after canola and barley is advisable for Shahrekord region and other area with similar climate. This plant also had positive effects on production efficiency and soil fertility in rotation.

The new line (KAUZ/PASTOR//BAV92/RAYON CMSS00M02400S-030M-030WGY-030M-9M-0Y) (Gaboos cultivar) was evaluated at Gachsaran and Gonbad Agricultural Research Stations in the first time in 2006-2007. Due to optimum earliness, plant height, kernel weight and successful performance of grain yield in observation nursery, preliminary and advanced yield trials (2007-2009), this genotype along to 16 promised lines and check (Koohdasht cv.) studied during three years (2009-2012) in uniform regional wheat yield trials in Gachsaran, Khoram Abad, Gonbad and Ilam stations. Three years average of grain yield across all stations for new cultivar was 3514 kg/ha which showed significant difference at 5% probability level in compare to check (3333 kg/ha), and also, considered line had 17 and 11 percent grain yield increasing with significant preference at 5% and 1% probability level in Gachsaran and Gonbad stations respectively. In view of stability parameters, Gaboos cultivar had the best rank with low standard deviation and small within location coefficient of variation among all advanced lines. Koohdasht cultivar (check) had seventh rank with partially high standard deviation of rank, but, the least within location coefficient of variation. Mean while, it has good preference for qualitative characteristics particularly: protein percent, wet gluten, gluten index, water absorption, seed hardiness, zeleny number, sodium dodecyl solphat and bread volume in compare to check. New cultivar has not showed remarkable susceptibility to important current diseases such as yellow rust, brown rust, common bunt and Fusarim head blight in warm dry land stations under natural infection and artificial inoculation conditions.

In order to investigate the effects of super absorbent material on water saving and increasing rain water productivity under micro catchments water harvesting systems, a field experiment was conducted in East Azarbaijan. The treatments included two MCWH patterns (small basins and semi-circular bunds), three catchments sizes, three runoff area treatments (Natural, cleared and smoothed, wetting and compacting) and two-infiltration areas (Natural, soil mixed with polymer at a rate of 1kg/tree) for two new almond varieties. Results of this experiment in comparison with farmer fields (traditional and irrigated) showed that super absorbent material had non significant effect on water holding and almond trees growth. Total length of branches created under polymer and without polymer treatments were 432 and 393 cm, respectively and stem thickness changes during crop season for these treatments were 48.3 and 46.1%, respectively. The optimal treatment was 49 square meter runoff area which cleared, smoothed and compacted and without polymer can be recommended. Under these conditions, using animal manures, evaporation control and soil changing is necessary for improving soil water contents on infiltration area. The fruit yield is estimated to 3 kg per tree, totaling 612 kg.ha-1 for the recommended treatment.
