In the second study the effects of Sulphur (0, 150 and 300 kg.ha-1), thiobacillus bacteria (50:1 weight ratio of sulfur and bacteria) and cow manure (0 and 30 ton.ha-1) was evaluated on yield and yield components of black seed. Results showed that the effect of experimental factors was significant only on number of tiller, number of spike and SPAD reading in isabgol. The highest amounts of tiller and spike (5.6 and 48.5 number, respectively) was obtained by 2 kg.ha-1 humic acid application, while their lowest (3.8 and 31.6 number, respectively) was belonged to control treatment. Application of cow manure and humic acid increased partially the swelling factor of seeds. In addition, the highest seed yield (3.76 g per plant or 1038 kg.ha-1) was obtained at the rate of 2 kg.ha-1 humic acid usage. In the second experiment, the impact of experimental factors was not significant on black seed medicinal plant growth indices. However, almost all of studied criteria were improved by cow manure consumption, so that finally the seed yield of the plant was 292 and 243 kg.ha-1 in application and no-application cow manure treatments, respectively. overall, our results revealed that isabgol and black seed are two low-input medicinal plants in terms of nutrients requirements.

The main plots composed of two sowing dates (4 and 25 June considered as the optimum and late planting date, respectively) and two levels of water stress (Normal irrigation and withholding irrigation at early silking). Three sweet corn hybrids including KSC403su, Passion, and Signet were considered as sub-plots. Delay in sowing date and water stress significantly reduced fresh ear yield and its components, plant height, ear length, and fresh forage yield in all three hybrids. The KSC403su hybrid showed superiority and the highest fresh ear, kernel, and forage yields when seeds were planted on time and irrigated normally. Under withholding irrigation at early silking and planting on time, yield reduced the most by 45% in KSC403su. Under late planting date and water stress condition, the highest yield reduction was observed in Signet by 44% whereas, the lowest yield reduction was observed in Passion.

Before starting the experiments, seeds of wild mustard (Sinapis arvensis) and white mustard (S. alba) were collected from East Azarbaijan and Khuzestan provinces at maturity (late spring and early summer) during the 2015-2016 growing season and were stored for seven months. This study included three experiments. Each experiment was arranged in a completely randomized design with four replications, and the treatments were factorial. In all experiments, one of the factors was the mustard species. In the first experiment, the second factor consisted of eight temperatures ranging from 5 to 40 °C. In the second experiment, the second factor was 13 sowing depths of 0.5 to 6 cm. In the third experiment, the second factor included six flooding periods from 0 to 35 days. The results of the experiments showed that in most temperatures, the depths and flooding periods, germination of wild mustard were greater than white mustard, which is probably due to the larger size of the seed of this species. The onset of mustard germination was from 4 to 5 °C (base temperature) and peaked at temperatures from 25 to 30 °C (optimal temperature) and then germination stopped at 40 to 45 °C (maximum or ceiling temperature). Considering that with increasing depth, the percentage and rate of emergence in both species decreased.

Iran Journal Article 2017 04 17 Induced resistance was studied in two resistance and susceptible (Naz and Akhtar, respectively) common bean cultivars against two spotted spider mite, Tetranuychus urticae Koch (Acari; Tetranychidae(. In this study the amounts of total phenols, malondialdehyde, antioxidant activity, and the activity of plant defensive enzymes [guaiacol peroxidase (GPX), and ascorbate peroxidase (APX)] were measured for uninfected (control) and infected (1, 3 and 5 days after infestation) plants. The amounts of total phenols and antioxidant activity were higher in cultivar Naz (max: 0.8 and 53.67 respectively) compared to Akhtar, but the amount of malondialdehyde was low in Naz. Also, cultivar Naz exhibited greater enzymatic activity (GPX: 37.29 and APX: 21.87), than cultivar Akhtar. These results suggested that the plant defensive enzymes such as GPX, and APX were involved in common bean resistance to T. urticae. Thus, increased activity of GPX and APX along with accumulation of total phenols increased plant resistance to T. urticae.

High genetic diversity for salinity tolerance has been observed in Iranian bread wheat genotypes. In this study to finding interrelationships between different traits and performance evaluation of wheat genotypes was used biplot method. In this study, 110 bread wheat genotypes were evaluated in two conditions (non-stress and saline stress) at the research field of the National Salinity Research Center (NSRC). The salinity of water used in irrigation in saline and non-stress conditions was 10 and 2 dS.m-1 respectively. The results revealed that there was a strong positive association between biological yield and harvest index with seed yield in both non-stress and saline conditions. Therefore, it seems that biological yield and harvest index could be used as a suitable criterion in selecting for increased seed yield in wheat in both non-saline and saline conditions. In this research among 110 studied bread wheat genotypes, promising advanced lines Salt22, Salt29 and Salt30 were identified as the most salinity-tolerant genotypes that these lines can be utilized for salt-affected areas and as donor parents in wheat breeding programs for further improvement of germplasm for salinity tolerance.

Results showed that yields of cereal forage and mixed forage in Z:G were significantly higher than P:G. Cereals were dominant component in intercrop and the dominance of maize was higher than millet. Intercropping system or pattern did not affect total land equivalent ratio (LER).The highest LER was recorded 1.15 by P%100G%25 in 2013 and 1.07 by Z%83G%67 in 2014 without 2nd cut of pearl millet, and 1.10 by PGG in 2014 with sum of 2 cuts of pearl millet. In X%83G%67 despite the 83% cereal density of monoculture, partial LER was 0.95 for maize but 0.70 for pearl millet. It is concluded that additive patterns with a small ratios of soybean or with some decrease in ratios of cereal component, tend to have potential to achieve higher LERs.

Journal Article 2017 12 23 A total of 17 wheat landraces were evaluated for resistance to powdery mildew in filed and greenhouse environments. The field experiment was performed at three disease hotspots in Sari, Gorgan and Moghan under natural disease incidence and the reaction of the genotypes was evaluated at adult plant stage. In order to evaluate the resistance of the genotypes at seedling stage, the isolates of the disease were collected from different regions and the pathotypes were identified by inoculation on the differential varieties. The results of field evaluation indicated that average reaction level of genotypes to the disease in Sari and Gorgan was similar and both lower than that of Moghan. A total of ten pathotypes were distinguished, all of which had virulence factors for Pm3a, Pm3c, Pm3g, Pm4a, Pm5, Pm6, Pm8 and Pm2. The varieties Shamrock (with unknown R gene), Normandie (Pm1+ Pm2+ Pm9), Axona (Pm2+Pm3d+Mld), Maris Dove (Mld+Pm2) and Wembley (Pm12) were resistant to all the pathotypes. The presence of Pm7 was postulated in genotype 7 as the resistance spectrum of this genotype was similar to that of Transfed. Genotypes 4 and 11 appeared resistant and moderately resistant at adult plant stage while they were susceptible to all pathotypes at seedling stage and therefore they were identified as genotypes with adult plant resistance. The total results of this research led to identification of seedling and adult plant resistance sources with different resistance gene combinations which could be exploited in breeding programs.

The spikes were harvested at Zadoksstage 92 and the seeds moisture content was measured immediately after harvesting.Two methods were used to evaluate pre-harvest sprouting including sprouting score and sprouting index under laboratory condition. The studied traits were as follows: seed dormancy, after ripening period, α-amylase activity and embryo protein levels under laboratory conditions. In both methods, high resistance to sprouting on the spike was observed in cultivars with high levels of seed dormancy.Significant differencesamong studied cultivars were observed forphenological, physiologicalandbiochemical characteristics of rice grain.Meanwhile, there were significant positive correlations between sprouting score, and sprouting index with α-amylase activity, there were significant negative correlationbetween these two traits with seed dormancy index (dormancy severity) and after-ripening regression coefficient (dormancyduration).

The combination factorial of fertilizer treatments (vermicompost, urea and non-fertilizer), irrigation methods (alternate and conventional) and irrigation interval (6, 12 and 18-days) were main factors and two cuts were sub factor. The highest dry weight of forage was obtained by six and twelve days conventional irrigation intervals. The highest dry weight of leaf and stem was observed in six days conventional irrigation intervals with vermicompost application. The first cut had the highest NDF by 34% and Potassium by 3.8%. The highest crude protein of 21.9% was observed in the second cut with application of vermicompost and conventional irrigation. The four-way interaction between cut, fertilizer, irrigation interval and method was significant for phosphorous concentration. According to the results, vermicompost can mitigate the effect of deficit irrigation on sainfoin and in the absence of any fertilizer, there was no significant difference between irrigation regimes in terms of yield. On the other hand, the use of alternate irrigation with longer intervals, especially in the first cut, can be investigated according to weather conditions, cost-effectiveness and low differences with other irrigation regimes.
