For determination of cooking quality characteristics of advanced clones and potato cultivars, this experiment was conducted to determine the quality characteristics on the three advanced clones (397009-3, 397082-2 and 396156-6) and three potato cultivars (Agria, Marfona and Savalan) under in vitro condition in Ardabil, Iran in 2009. Experimental design was completely randomized with three replications. In the study some of characters were measured such as dry matter and starch percent, specific gravity, french-fry and chips color and quality, cooking type, texture firmness and flavor. Analysis of variance showed that significant differences between cultivars and clones for tuber yield, dry matter and starch percent, specific gravity, french-fry and chips color and quality and reducing sugars amount. The 397082-2, 396156-6, 397009-3 clones and Savalan cultivar had the highest yield. The highest dry matter, starch and specific gravity belonged to 396156-6 and 397009-3 clones and Savalan cultivar. These cultivars had C cooking type. Therefore, the 396156-6 clone and Savalan cultivar are recommended for chips production, 397009-3 clone for french-fry, chips and starch production. The Marfona cultivar had a lower dry matter and B cooking type. Potatoes of this type are suitable for eating boiled, mashing and fresh and conserve potato consumption. |

This experiment was done for evaluation the effects
of potassium humate on seed germination, yield and yield components and
seed planting method to commercial used of F1 true potato seed. This research
was conducted in Ardabil (Iran) during 2007 and 2008. HPS-II/67 hybrid
seed 3500 were grown after treatment in seven different times by potassium
humate (for 6, 12, 18 and 24 h till complete germination in potassium
humate solution, till complete germination in water and without using
the potassium humate and water as control). Potassium humate was used
40 mL kg-1 seed in 2 L of water. Then seeds were transferred
to greenhouse and planted in peat mass bed (Biolan). During growth period
were measured the traits such as start and seed germination percent and
day number from planting till germination in laboratory and greenhouse.
Seedlings transferred in 4-5 leaf stages to field. Experimental design
was randomized complete blocks with three replications. After harvest,
were measured the traits such as tuber number and weight per plant, tuber
weight average per plant and tuber yield. Results showed that among different
treatments of potassium humate there is significant difference for the
tuber number and weight per plant, tuber weight average per plant and
tuber yield. The maximum seed germination percent, tuber number and weight
per plant, tuber weight average per plant and tuber yield produced in
6 and 12 h treatment by potassium humate. Direct planting of TPS in compare
with the planting after seed germination in potassium humate and water
caused to increase tuber yield. In this experiment, seed treatment by
potassium humate for 6-12 h and seed direct planting in greenhouse percent
without seed germination under in vitro, caused to increase seed
germination percent and tuber yield. |

In order to evaluation of drought stress tolerance of seven onobrychis genotype in vitro condition, was done in Ardabil, Iran in 2009. This experiment was performed by use of factorial design on the basis of completely randomized in three replications. A factor includes five osmotic potential levels (0, -3, -6, -9 and -12 bar) and B factor includes seven onobrychis genotypes (Syntetic, Mako Shoot, Osko Asfanjan, Khosro Shahr Tazekand, Osko Askandaran, Ardabil Garjan and Ardabil Hasanbarogh). For making the different osmotic potentials were used the PEG 10000 and distilled water as control. The variance analysis results showed that there is significant difference between drought levels, genotypes and their interaction as attributes such as coleoptile length, germination uniformity and percent, between drought different levels as attribute germination speed. The Synthetic genotype had the most coleoptile length, germination uniformity and germination percentage in -3 bar and control in compare of the other genotypes. Synthetic genotype showed the most tolerance to drought stress in comparison of the other genotypes and selected the tolerant genotype. |

This experiment performed according to the factorial design and on the base of completely randomized design in three replications in 2007. Factor A included four levels of osmotic pressure (0, -1, -2 and -3 bar) and factor B included seven advanced potato cultivars (Agria, Savalan (397007-9), Satina, Caesar, Kennebec, Marfona and Sante). The PEG 6000 was used for exerting the water deficiency stress on the plantlets. The attributes such as germinating ability and root producing was measured. In this stage the cultivar that produced the roots, had moved to the greenhouse. The plantlets were planted in soil bed with mixed of Punce and Biolan with 1:1 v/v. The applied experimental design was factorial on the base of completely randomized design in three replications. Factor A has four levels of osmotic pressure and factor B included seven advanced potato cultivars. After two months, was harvested the mini-tubers and the attributes was measured such as mini-tuber average size, mini-tubers weight and number per plant. The variance analysis results showed that significant difference between osmotic pressure levels, cultivars and their interaction as attributes mini-tubers number and weight per plant and mini-tubers average size in 1% probability. The Caesar and Savalan cultivars had the most number and weight of mini-tuber per plant in -1 bar and Caesar and Kennebec cultivars in -2 bar osmotic pressures. The MP, GMP, STI and MSTI selected Caesar as better cultivar in normal and stress conditions. Results of cluster analysis showed that cultivars grouped in three clusters. The first cluster included Agria, Sante and Marfona (susceptible cultivars), the second cluster Satina, Savalan and Kennebec (moderately tolerance cultivars) and the third cluster Caesar (tolerance cultivar). |

This experiment carried out to evaluate the effects of planting methods (seed sowing and transplanting) and head pruning (no pruning, pruning after 12th node and pruning after 16th node) on yield and yield components such as number of branches (sub-branches) per plant, fruits per plant, growth, fruit size, weight of fresh fruit, weight of seeds per fruit, number of seeds per fruit and seed yield of medicinal pumpkin. The experiment was carried out based of factorial experiment with Randomized Completely Blocks Design (RCBD) by three replications in Ardabil Agricultural and Natural Resources Researches Station at 2007. Seedlings were grown in heated greenhouse. When the climatic condition became suitable and seedlings were at the four leaves stage, both seeds and seedlings were planted at the same time in the farm. Maintenance operations were done during the growth season. Head pruning treatments were done the forecast time. The results showed that the planting methods had significant effect on the number of ripen fruits per plant, fruits diameter, weight of seeds per fruit, weight of 1000 seeds and seed yield and had no significant effect on the other traits. Also the results indicated that head pruning treatments had significant effects on the number of branches per plant, growth and seed yield and no significant on the other traits. In this experiment the most seed yield (997.8 kg ha-1) obtained from transplanting method with head pruning after 12th node and the least seed yield obtained from control. |

This experiment were conducted with three cultivars
of potato such as Agria, Satina and Caesar and four irrigation regimes
(after 30 mm evaporation from class A evaporation pan, after 30 mm evaporation
from class A evaporation pan with spraying by potassium humate, after
60 mm evaporation with spraying by potassium humate and after 60 mm evaporation
from class A evaporation pan) in three locations of Ardabil in Northwestern
Iran during 2007-2008 with split plot method. Potassium humate sprayed
(250 mL ha-1) in the three stages of emergence, before tuberization
and during tuberization period. Combined analysis of variance showed that
were significant differences between locations, years, irrigation regimes
and cultivars and their interaction on tuber yield. According to the NPi(1),
NPi(2), NPi(3), NPi(4)
and NPi(5) methods, Satina and Caesar were
stable but Agria unstable and had the lowest value. Caesar cultivar is
most stable and adapted across environments well; the highest mean of
rank and yield and high ranking under normal, stress with potassium humate
and stress conditions. In this study nonparametric statistics (S1(1))
selected. |

In this study yield and yield component, Harvest Index
(HI), Stress Tolerance Index (STI), Stress Susceptibility Index (SSI),
Tolerance Index (Tol), Mean Productivity (MP) and Geometric Mean Productivity
(GMP) of 13 advanced winter and intermediate cold hardy wheat genotypes
with two advanced genotypes of Shahreeyar and C-79-16 as checks were investigated
under normal irrigation and after anthesis drought stress condition in
a randomized complete block design experiment with three replications
in Ardabil, Iran in 2006-2007. The effect of drought stress on harvest
index was significant (p≤0.01). The lowest harvest index (38.14%) was
observed in genotype KRC66/SERI//KINACI97 and the highest harvest index
(45.66%) was observed in genotype FDL4/KAUZ. Genotypes KARL//…/3/F1502W9.01,
Appolo/Mhdv and SG-U7067 produced more grain yield under normal irrigation
condition compared to checks and mean stress susceptibility indices of
genotypes SG-U7067, 885K4.1//MNG/SDV1/3/1D13.1/MLT and GKRABA were lower
than checks. On the other hand, under the drought stress condition genotypes
SG-U7067, GKRABA and 885K4.1//…/1D13.1/MLT yielded higher than checks
and their mean stress susceptibility indices were lower than checks. Genotype
SG-U7067 produced the highest yield under both normal irrigation and drought
stress conditions. The yield reduction of this genotype was lowest under
the drought stress conditions. Genotypes SG-U7067 with mean grain yield
of 5.020 t ha-1 under drought stress, lowest SSI of 0.82 and
highest STI of 0.62 was selected as the best drought stress tolerant genotype
among the 15 genotypes that were evaluated. |

The direct measurement of erosion is very difficult
and expensive. So use of erosion and sediment models is important to determine
the amount of soil erosion. To determine the soil erodibility, has taken
300 soil samples from different fields with 0-12 cm depth that are located
in the Aras sub watershed in North West of Iran in 2005-2006. The soil
samples were analyzed and some factors such as soil texture, organic matter
were measured. By use of the factors the other factors such as soil structure
class, soil percolation class, total sand, fine sand, clay and silt percentage
was measured. The study used the soil structure class and percolation
to determine the soil erodibility. This study evaluates the effects of
soil erodibility and the factors on sediments amount in the hydrological
watersheds that have station to measure the sediment. Soil erodibility
was measured by the formula follow this: 100K = 2.1M 1.4x0-4xz(12
- % OM)+3.25(S-2)+(P-3). Soil erodibility and some factors such as soil
organic matter, fine sand percentage and soil structure class can predict
the amount of soil erosion. Analysis of variance and the means comparisons
with LSD test was done by MSTATC software. Linear correlation coefficients
between different traits were done by SPSS software. The variance analysis
results of the studied attributes showed that there is significant difference
among the erodibility, fine sand and soil structure class. The studied
location mean showed that Mashiran, Pole Almasi and Borran station in
comparison the other locations, had the most erodibility. Soil erodibility
cannot be the factor that has effect on the sediment producing in a station,
alone. This factor must be evaluated with other factors such as soil organic
matter, soil fine sand percentage, soil structure class, watershed area,
topography and plant cover. In the prospective research, we should improve
method to measure and calculate soil erodibility, strengthen the research
on the mechanism of soil erodibility and conduct research on soil erodibility
by both water and wind agents. |

The nitrate accumulation is one of the problems in potato production that causes to decrease the production quality. The nitrate accumulation can have more reasons such as excess use of fertilizers. However, this research has studied to find the solution for this problem. This study evaluated some material effects such as the effect of K-Humate on nitrate accumulation. This experiment was performed according to the spilt plot and as base of the complete randomized design with three replications and two factors. Main factor included four levels of irrigation treatments; normal, normal with potassium humate, stress and stress with potassium humate. Sub factor included three potato cultivars; Ceaser, Satina and Agria. Variance analysis results showed significant differences in total yield, marketable yield and nitrate accumulation in tubers. Tuber the most yield was under normal with potassium humate in Ceaser and Satina cultivars and tuber the less yield was under stress condition in Agria cultivar. The nitrate accumulation decreased under stress with potassium humate condition. |
