As compared to KSC 704 hybrid with 9.844 t/ha, the maize hybrid, KSC 705(K3640/3 × MO17) produced an average grain yield of 11.120 t/ha over seven locations evaluated in final trials for two consecutive years (2007-8). In advanced yield trials done in 2011, across seven locations, this hybrid performed the highest grain yield, 10.450 t/ha, while KSC 704 produced 8.513 t/ha. In addition to the grain yield preference, grain moisture in KSC 705 was about two percent less than KSC 704 at harvesting stage under farmers' conditions. Hybrid KSC 705 with an average of grain yield 10.585 t/ha showed 833 kg/ha (8.5%) superiority to KSC 704 (9.753 t/ha), once evaluated in adaptability trials conducted in nine locations for two years (2011-12). On farm experimental results obtained from Eslam Abad, Ravansar, Mahtabi and Shoosh in 2012 revealed that KSC 705 with an average grain yield and moisture of 12.617 t/ha and 20.94%, showed a superiority of 1.429 t/ha (12.8%) over the yield of KSC 704 (11.188 t/ha) and 2.31 less grain moisture comparing to KSC 704 with 23.25% grain moisture. Comparing to KSC 704, this hybrid was seven days earlier. In contrast to KSC 704 with a moderately susceptible reaction to common smut under artificial infection, KSC 705 was rated as a moderate resistant type. For fusarium ear rot, both hybrids were classified into moderately resistant hybrids' group.

Zafar as a new rapeseed cultivar is the cross which was made between 19H and Sarigol line/cultivar in 2003. The pedigree selection was applied to mange the segregating generations. The results of evaluation made during 2008-09 and 2009-10 showed that Zafar with an average seed yield of 3810 kg ha-1 was among superior genotypes identified. Further evaluation on these genotypes as a mid-maturity/spring type rapeseed lines was made under on-farm conditions in mid-lands/highlands of Mazandaran province. The results revealed that Zafar with an average seed yield of 2595 kg ha-1 was superior as compared to Sarigol as the local check cultivar. The results obtained from the experiments conducted under on-farm conditions of mid-lands of Mazandaran province in two locations demonstrated an average 800 kg ha-1 superiority of Zafar cultivar to the check, Sarigol. Additionally, Tolerance to sclerotinia root of Zafar was similar to the reactions of the local check varieties. This variety is considered suitable for cultivation in mid-land of Mazandaran province and similar climatic regions.

Crop’s water use efficiency (WUE) is one of the major indices for the efficient use of water for crop production in agriculture. Based on scientific literatures, the concept of WUE has been defined in all crop management, Farm/Field, and water Basin/irrigation network domains. Plant in particular, plays an important role in the efficient use of water and enhancement of WUE. Plant resistance to environmental stresses (e.g., drought, salinity, and heat stresses) and other plant physiological factors affecting biomass and yield in terms of water unit consumption, all could influence WUE in an individual plant scale. In this paper, the concept of crop WUE and associated challenges and approaches for enhancing WUE will be discussed through review analyzing of farmer’s fields and experimental result of WUE research projects in Iran. To enhance WUE crop plays a major role beside other water saving approaches. Therefore the related approaches and actions towards efficient enhancing of WUE should be linked and interrelated. Applying this kind of methodology is more practical and scientific achievements aiming food security with regard to limited water sources and development programs in Iran. In addition to the related technical concepts, field management and farmer’s knowledge and skills were considered key issues affecting WUE.

To study response of bread wheat cv. Sardari to row spacing and seeding rate and to determine the desirable seed density under cold rain-fed conditions a two-year study (2008 and 2009) was carried out in Qamloo research station located in Kurdistan. A strip plot design with three replications was used. Four rows spacing including 15, 17.5, 20 and 25 cm as horizontal factor and four seeding rates including 350, 400, 450 and 500 seed per square meter as vertical factor were assigned. Regardless of seeding rates results it was shown that the row spacing had significant effect on grain yield and its components including spike per square meter, thousand kernel weight and grain per spike. The highest and the lowest grain yield values, 3993 and 2695 kg/ha, were observed in rows spacing of 15 cm and 25 cm, respectively. Row spacing of 15 cm with 821 spike/m2 and 40 g TGW was located over the others. Conversely, the lowest and the highest grain per spike (13 and 16 grain) were observed in rows spacing of 15 and 25 cm, respectively. With respect to the results obtained (non-significance of seeding rate effect), the best recommendation of Sardari cultivation practices in cold high elevation rain-fed areas are row spacing of 15 cm and seeding rates of 350-400 grain /m2 or 140-160 kg/ha.

Clementine mandarin (Citrus clementina) is one of the suitable/marketable citrus species in north of Iran however, as a disadvantage has small fruits. In order to produce new citrus cultivar with large and good quality fruit, a project with four phases was conducted from 1989 until 2009. The first phase was started with controlled cross pollination between Clementine mandarin as maternal, and Marrs, Hamlin and Salustiana oranges (C. sinensis (L.) Osbeck) as paternal parents. The second phase of this project consisted of selection of superior genotypes based on their suitable characteristics e.g. earliness, low-seed content, fruit size, peeling quality, extract percentage and fruit tastearoma. Primary quantitative and qualitative evaluations of fruits based on optimum levels of aforesaid traits resulted in final selection of 68 hybrids among the 396 crosses made in the third phase. To choose the best performing hybrids, evaluation and adaptability of selected genotypes in comparison with Clementine mandarin (control), were tested under environmental conditions of northern Iran with the common rootstock, sour orange (C. aurantium L.). On the basis of good quantitative and qualitative traits, finally the genotype 76109 (a Clementine × Salustiana orange cross) was selected as new mandarin hybrid and named “Noushin” in Iran in March 2010. Noushin is moderately vigorous with an upright canopy and thorn less. Its fruits are medium-sized, almost oblate and seedy. Rind is thin, somewhat leathery, its fruit has nearly bumpy surface with prominent oil glands with an easily separable peels, light orange in color at the maturity stage and excellent taste. Noushin has early ripening/good quality fruits. As compared to its maternal parent, clementine mandarin, Noushin showed superiority of higher yield (10%), fruit weight (25%), TSS/TA (24%) and earlier time of fruit ripening (15 days). Considering these suitable traits and also based on its economical value and cold tolerance in orchard holders' view is expected to successfully commercialized as a new cultivar in the market.

Every year large amounts of grapes are stores in normal and cold rooms to offer off-season of grapes to the market which based on several reasons their quality and weight greatly decreases. Therefore, in order to decrease the post harvest losses of grapes and selection of suitable cultivars for long time storage, this study was conducted in two experiments, one in a factorial experiment based on randomized complete design (CRD) in three replications with two factors including cultivars (Sefide bidane and Qzel Ozum), and packaging type (one sulfur pad with perforated bag, ½ sulfur pad with imperforated bag, without sulfur pad with perforated bag, without sulfur pad with imperforated bag, without sulfur pad and without bag) and the other in a randomized complete design (CRD) with five packaging treatments and three replications for Rasha cultivar. Grape bunches were harvested and transferred to cold storage. To study the effects of treatments, some traits including bunch and berry shriving, bleaching, fungal rot (%), bunch appearance and taste were measured. Results showed that using one sulfur pad with perforated bag and ½ sulfur pads with imperforated bag treatments controlled fungal rots and bunch and berry shriving, and preserve bunch appearance and taste. Therefore with using this method, Qzel Ozum and Rasha, could be stored in cold rooms for five months and Sefide-bidane for three months.
