In order to study the effect of seed aging, plant density, and nitrogen fertilization on physiological and yield characteristics of wheat, an experiment was performed as a split plot based on RCBD with four replications in 2015-2016. Experimental factors were three levels of nitrogen in recommended amount, 15 and 30 percent more than the recommended amount (125, 143.75, and 162.5 kgN.ha-1, respectively) and plant density at two levels, namely 350 and 420 plants per square meter which were the main plots and seed quality at four levels including control, 15, 30, and 45 hours of accelerated aging was subplots. Grain yield, protein and starch performance were significant under the triple effects of seed quality, planting density, and nitrogen fertilizer. With increasing levels of seed aging significant reduction were observed in all traits (except grain protein and nitrogen percentage). Application of nitrogen fertilizer 30 percent more than the recommended dose, as well as plant density of 420 plants per square meter significantly increased grain protein and nitrogen percentage. The highest average protein yield was achieved in the combined treatment of 350 plant square meters at 30-hour aging level and nitrogen fertilizer at 15 percent more than the recommended dose and also in combined treatment of 420 plant square meters, 45-hour aging level, and the nitrogen level 30 percent more than the recommended dose. Generally, seed deterioration reduced its quantitative and qualitative characteristics but more nitrogen fertilizer improved quality traits, thereby improving the quality loss. Manuscript profile

In order to determine the water requirement of sunflower cultivars, an experiment was conducted during 2015-2016 at Ardestan Station, Isfahan. The experiment was carried out in a factorial randomized complete block design with four replications. Treatments included 3 irrigation regimes (D1: irrigation after 60 mm, D2: irrigation after 120 mm, D3: irrigation after 180 mm evaporation from small tub evaporation) and 5 sunflower cultivars (Azargol, Prograss, Gabur, Hysan 25, and Hysan 36). Results showed that under non-stress and moderate stress, Azargol and Prograss cultivars had the highest rate, in terms of seed filling period, the weight of 1000 grains, stem diameter, and head diameter. Under severe stress, Prograss and Gabur cultivars were remarkable, so that Prograss cultivar had the highest seed filling period, weight of 1000 grains, stem diameter, and Gabur cultivar had the highest number of budding, number of flowering, and stem diameter. In the study of physiological characteristics, results showed that under non-stress and moderate stress chlorophyll a, b, total chlorophyll, and net-photosynthesis in cultivars Progerass and Gabor were significantly increased compared to other cultivars. In severe stress conditions, the Progress and Gabor cultivars in chlorophyll a, b and total chlorophyll content were superior to other cultivars. The results of proline analysis indicated that proline leaf content increased significantly with water stress. Among the cultivars under severe stress conditions, proline leaf content in Progerass and Gabor cultivars was significantly higher than other cultivars. The results of this study showed that Azargol, Gabor, and Progerass cultivars are more tolerant than Hysan 25 and Hysan 36.   Manuscript profile

This experiment was conducted with the aim of evaluating the planting systems of local rice cultivars in the research paddy fields located in Neka, Sari and Babol during 2017 and 2018. Data analysis was done based on a factorial experiment in a complete randomized blocks design where planting systems including conventional, high-input, transition to organic, organic, and low-input were chosen as the first factor and cultivars including ‘Sang Tarom’, ‘Tarom Mahalli’, and ‘Tarom Hashemi’ served as the second factor. Results demonstrated that the highest mean number of panicle per m2 in both years belonged to the high-input system. The highest fourth internode lodging index was obtained at interaction of high-input and conventional system with ‘Sang Tarom’. The maximum paddy yield in both years was produced in high-input and conventional systems. The highest grain phosphorous uptake, nitrogen harvest index, potassium harvest index, and gel consistency were achieved in high-input and conventional systems. The highest grain milling efficiency in the first year belonged to the conventional system (72.83%), but in the second year, it belonged to the transition to organic system (75%). Gelatinization temperature in both years was maximum in the conventional system while it was minimum in the low-input and organic systems. Regarding the findings, it can be stated that high-input and conventional systems resulted in increase of quantitative yield, but organic and transition to organic systems led to an increased NPK uptake and improvement of the grain baking related traits.

In order to investigate the effect of nitrogen and sulfur on quantitative and qualitative yield of rapeseed, a factorial experiment was conducted in a randomized complete block design with three replications in Research Field of Shastklateh Forest of Gorgan in 2018. Four amounts of nitrogen fertilizer 25, 50, 75 and 100 kg of pure nitrogen per hectare (from urea source) as the first factor, two amounts of sulfur fertilizer to zero (control) and 200 kg / ha as the second factor and two spring rapeseed genotypes Hyola 50 hybrid and ARGS 003 were selected as the third factor. The results showed that biological yield, grain yield, 1000-grain weight, number of pods per square meter, number of seeds per pod, protein percentage and oil percentage were affected by cultivar, nitrogen and sulfur. Comparison of the average interactions of nitrogen and cultivar showed that biological yield (8360 kg/ha), grain yield (275.6 g/m2), 1000-grain weight (4.1 g), number of pods per square meter (5323.53), Number of seeds per pod (31.64) and grain protein (24.32%), Soluble sugar (33.35 μmol/g) and total chlorophyll (1.38 mg/g) at the level of 100 kg N/ha and Hyola 50 hybrid cultivars and the highest grain oil (41.65%) at the level of 75 kg N and hybrid cultivars Monsters 50 were observed. Also, the comparison of the mean of the interaction of sulfur and cultivar showed that the highest number of latere better ability to absorb and transfer nitrogen and sulfur and therefore produce more yield.
