  In order to study the effects of nitrogen and irrigation interval on Broomrape (Orbanche aegyptiaca) damage reduction in cucumber (Cucumis sativa L.), an experiment with two factors, nitrogen (urea in three levels 100,200 and 300 Kg/ha) and irrigation interval (with three levels 3,6 and 9 day) in three replications was performed in the greenhouse of Northern Khorasan Agricultural and Natural Resource Research Center. The results showed that the growing velocity was maximum in the treatment of 200 Kg N/ha. However, height and the number of cucumbers were lower. The effect of irrigation interval on the number of flowering days was significant, whereas nitrogen fertilizer did not have a significant influence on this parameter. Hence, irrigation level rising caused reduction in the number of flowering days. Maximum length and diameter of cucumber was observed in the treatment of highest nitrogen level and minimum irrigation interval or the treatment of lowest nitrogen level and medium irrigation interval. The maximum number of cucumbers and weight was obtained in maximum nitrogen and irrigation interval. In addition, rising irrigation interval caused the number of cucumber increase and decrease in cucumber weight. The maximum wet weight of shoot and root was observed in the highest nitrogen treatment. On the other hand, the maximum wet weight of shoot and root was derived from the highest nitrogen and medium irrigation treatment and the highest nitrogen and minimum irrigation interval treatment, respectively. The comparison of water percent in wet and dry weight of shoot showed that the highest value was observed in 300 and 100 Kg N/ha treatments respectively. Maximum shoot/root ratio was observed in the treatment of 100 Kg N/ha and a six-day irrigation interval. Manuscript profile

  To evaluate different irrigation regimes and planting dates on plant height, stem diameter, yield, and yield components of okra (Abelmoschus esculentus L.) a split plot experiment based on randomized complete blocks with three replications was conducted in Karaj during 2017 growing season. Experimental treatments were irrigation intervals (8, 10 and 12 days) as a main plot, and planting dates with three levels (4th, 18th of June and 2th July) as a sub-plot. The results of analysis of variance showed that the main effect of irrigation interval was significant on all traits under study. Planting date treatment had a significant effect only on plant height, stem diameter, number of plant branches, number of plant leaves, number of fruits, fresh fruit yield and dry fruit yield. The interaction of irrigation interval treatment and planting date had no significant effect on the trails under study. The highest chlorophyll concentration (3.68 mg.g-1 FW), plant height (100.4 cm), number of branches (3.1), number of leaves per plant (24.8), number of fruits per plant (10.5) and fresh fruit yield (4023 kg.ha-1) were belonged to the irrigation interval of 8 days. Irrigation interval of 12 days decreased by 30.4, 21.7, 21.3 and 28.4 % in stem diameter, fruit length, fruit diameter and dry fruit yield, compared to irrigation interval of 8 days interval, respectively. The highest plant height (99.2 cm), number of branches (2.5), number of leaves per plant (23.3) and number of fruits (9.77) were observed of June 4th planting date. The highest fruit yield was obtained in June 18th planting. Based on the results obtained it can be concluded that irrigation interval of 8 days is recommended to achieve maximum fruit yield and to shorten the length of growing period, saving in water consumption and maximum yield performance in the Karaj region, the date of 18th June is recommended.

  In order to evaluate different irrigation regimes and planting date on yield, water use efficiency, and harvest index of Roselle (Hibiscus sabdarjffa L.), an experiment was conducted in form of split plot in randomized complete blocks with three replications in Karaj in 2017. Experimental treatments included irrigation round (Irrigation intervals of 8, 10, and 12 days) as a main plot, andplanting date treatments at three levels of 4th June, 18th June, and 2th July as a sub-plot. Results showed that the main effect of irrigation treatments was significant on all traits except harvest index. Planting date had a significant effect only on plant height, stem diameter, biological yield, flower water use efficiency, and sepal water use efficiency. The interaction of irrigation treatment levels and planting date only made a significant difference in biomass water use efficiency. Also, the flower harvest index was not affected by any of the applied treatments.The greatest plant height (181.2 cm), stem diameter (2.91 cm) and biological yield (14.6 t.ha-1) were obtained in the irrigation interval of 8 days. The highest sepal water use efficiency of (0.18 g.L-1), flower water use efficiency (0.034 g.L-1) and sepal harvest index (11.12 %) were observed in the irrigation interval of 12 days. The irrigation interval of 10 days had the highest sepal yield (1.59 t.ha-1) and flower yield (307.7 kg.ha-1).Delay in planting caused a decrease of 12, 16, and 7% in plant height, stem diameter, and biological yield, respectively and increase in the sepal water use efficiency and biological yield water use efficiency by 22 and 20%, respectively compared to optimum planting time. The highest biological yield water use efficiency (2.41 g.L-1) was obtained in irrigation interval of 12 days and one month delay in planting. Based on the obtained results, irrigation interval of 10 days is recommended to achieve maximum flower yield and sepal yield, increase the flower water use efficiency and sepal harvest index. Also, in order to shorten the cultivation period and save water consumption, the date of 18th June is recommended for plant cultivation in Karaj. Manuscript profile

  To evaluate the effect of potassium humate (PH) on drought stress in potato cultivars (Kaizer, Agria and Satina) a split plot experiment based on randomized complete block design with 3 replications was performed. Main factor was irrigation regimes, 1- irrigation every 7 days without PH application, 2- irrigation every 7 days + PH application, 3- irrigation every 10 days without PH application and 4- irrigation every 10 days + PH application, in which 250 ml of PH diluted in 300L water and plants were sprayed in three stage of plant growth: full emergence, before and after tuber initiation. Results showed that increasing irrigation interval decreased stem number per plant from 3.5 to 2.5, days to flowering from 60 to less than 50 days, , and tuber yield from 45 to less than 35 ton.ha-1. Cultivar×irrigation interaction in all attributes were not significant. The highest tuber yield produced by Kaizer (55 t.ha-1) when plants were irrigated every 7 days irrigation + PH application and lowest by Agria (20 t.ha-1) in 10 days irrigation interval without applying PH. Kaizer not only produced high yield but also produced higher yield in every 7 or 10 days irrigation without PH application: 50 and 20 ton.ha-1, respectively. It seems that Kaizer could be a proper choice to be planted in drought prone regions like Ardabil. Applying PH resulted in increasing yield from 25 to 50 t.ha-1 under water deficit condition.

  In order to survey the effects of irrigation and foliar application of micronutrients on vegetative growth, yield and yield components black cumin ( Nigella sativa L. ), an experimental design was conducted in the research farm of North Khorasan agricultural and natural resources research center in Bojnourd in 2009. Experimental design was split plot based on randomized complete block design with three replications. The main factors were irrigation intervals in three levels ( I1=7, I2= 14, I3=21 days ) and subfactors were foliar application micronutrients included M1 = control ( no foliar application ), M2= foliar application with the zinc ( concentration of three parts per thousand ), M3 = foliar application with the Boron ( concentration of two parts per thousand ), M4 = foliar application with the iron ( concentration of four parts per thousand ), and M5 foliar application with the mixture of above elements. Experiment results showed that the impact of irrigation intervals on plant height, branch number, number of capsules per plant, biological yield and seed number per plant , seeds per capsule, seed weight, harvest index percentage, and seed yield, was significant and decreased with increasing irrigation intervals. The effects of foliar application of micronutrients on plant height, branch number, number of capsules per plant, biological yield, and Fe, Zn, and Br concentration in plant organs was significant. Foliar application of micronutrients caused plant height, branch number, number of capsules per plant, biological yield and Fe, Zn, and Br concentration in plant to be increased. Foliar application of micronutrient and irrigation interaction on plant height and biological yield were noticeable. Seven days irrigation intervals and foliar application, the mixture of micronutrient treatment caused the highest plant height, biological yield and Fe, Zn, and Br concentration in plant organs.

  In this decade, plants with low requirements which may contribute to human health have been increasingly considered. To investigate the effect of irrigation interval and foliar application of micronutrients on Panicum miliaceum, an experiment was conducted as split plot arrangement based on randomized complete block design with three replications in Sarbisheh agricultural research farm in 2012. Treatments including irrigation interval (7, 14 and 21 days) and foliar application of micronutrients in four levels (foliar application of manganese, zinc, zinc manganese and without foliar application) were assigned to main plot and sub plot, respectively. By decreasing irrigation interval to 7 days, the grain yield was increased mainly through increasing the number of grains per panicle (28% towards 21 day irrigation interval) and increasing the number of panicles per plant (25/68% towards 21 day irrigation interval). The foliar application of micronutrients improved the grain yield through enhancing grain number per panicle (23/29% towards treatment without foliar application) and enhancing panicle number per plant (15/17% towards treatment without foliar application). Findings showed that decreasing irrigation interval to 7 days and foliar application of micronutrients increased the yield and yield components of Panicum miliaceum. The maximum grain yield (222/6 grams per square meter) was under 7 day irrigation conditions and foliar application of manganese and zinc. Manuscript profile

  In order to study the effects of organic and nanobiologic fertilizers with three intervals of irrigation on seed yield of sesame (Sesamum indicum) a field experiment was conducted in Touredan region of Khonj in 2012. The experimental design was split plot based on Randomized Complete Blocks Design with three replications. Treatments included: fertilizer treatments with 8 levels (control, manure, compost, manure + compost,  nanobiologic, nanobilogic + manure, nanobiologic + compost and  nanobiologic + manure + compost) as first factor and irrigation intervals with 3 levels (8, 12 and 16 days) as second factor. Results indicated that irrigation intervals had no significant effects on studied traits such as seed yield, 1000- seed weight,  height of main stem and number of capsules. But irrigation intervals influenced shoot dry weight and leaf area significantly. Also fertilizer treatments had significant effects on traits in this experiment. Interaction between fertilizer treatments and irrigation intervals was significant in 0.05 probability level. Also interaction between treatments and different irrigation intervals was significant at 0.05 probability level. In general the effects of fertilizer treatments and irrigation intervals fertilizer treatment (Nano + Compost) with irrigation interval (16 days) was suggested as the best treatment in condition of the experiment.

  The present study was conducted to evaluate the efficiency of the HYDRUS model in simulating soil water movement and redistribution of moisture around the roots of maize in homogeneous and heavy soils. This study was carried out in the Agricultural Research Center of Khuzestan Province under drip strip irrigation with three irrigation regimes of 2, 3 and 4 days with three replications during two cropping years. In order to monitor the moisture around the roots, dig a soil profile to a depth of 75 cm perpendicular to the drip irrigation strip. Observed and simulated moisture values were compared byR2,EF, MAE and RMSE statistics. The results showed that the average moisture distribution in each irrigation regime is in the range of crop capacity. RMSE values for different diets ranged from 1.29 to 2.40% and MAE values for different diets ranged from 1 to 2%. Moisture simulations were classified as excellent based on MAE and RMSE values.Also, the results of the coefficient of explanation are between 60 to 90% and the efficiency of the model is between 40 to 90%. Based on the results, the lowest efficiency of the model was in the simulation 24 hours after irrigation and the best simulation was 72 hours after irrigation. The results show the high capability of the model in simulating soil volumetric moisture. Manuscript profile

  The present study was done in order to investigate the effect of Zn, B and Mn on yield of safflower under different humidity conditions in spring and summer of 2015 in Qazvin. This experiment as split plot design as RCBD in 3 replications was conducted. The studied factors included: irrigation interval in 3 levels (I1: irrigation every 6 days, I2: irrigation every 9 days, irrigation every 12 days) as main plot and foliar application in 8 levels (M1: Zn, M2: B, M3: Mn, M4: B Zn, M5: Zn + Mn, M6: Mn + B, M7: B + Zn+ Mn, M8: Water) as sub-plots were considered. Results showed that effects of irrigation and foliar application were significant on grain yield of safflower. The highest grain yield belonged to irrigation every 6 days with mean of 1584 kg/ha and the treatments of irrigation every 9 and 12 days with means of 1438 and 1306 kg/ha had the least grain yield that it were in a common statistically group. The treatment of B + Zn+ Mn with mean of 1579 kg/ha had the most grain yield and the least grain yield was observed in control (water spraying) with mean of 1262 kg/ha. Manuscript profile

  In order to investigate the effect of irrigation interval and harvesting time on agro-morphological traits of anise (Pimpinella anisum L.) a field experiment was conducted at College of Agriculture, University of Zanjan in the spring of 2011. The experiment was conducted as split plot based on a randomized complete block design with three replications. Main Factor was irrigation interval at three levels including every 7, 12 and 17 days irrigation and three harvesting times including harvesting at soft dough (waxy), hard dough and full maturity stages were assigned to the sub plots. The results indicated that the effect of irrigation intervals on majority of measured traits including number of umbrella in plant, number of seeds in main branch umbellet, number of seeds in sub branch umbellet, number of sub­-­branches in plant, number of umbellets in main branch umbrella, plant height, grain yield and biomass was significant. Majority of measured traits significantly decreased with increment in irrigation interval from 7 to 17 days. So, the highest biomass (1845.89 kg.ha-1) and grain yield (636.07 kg.ha-1) were obtained in 7 days irrigation interval and the lowest amount of the mentioned traits was observed in 17 days irrigation interval. Harvesting time had significant effect on some of traits including number of seeds in sub­-branch umbellet, biomass and grain yield. With delay in harvesting time from hard dough to full maturity stage, number of seeds in sub­-­branch umbellet, biomass and grain yield decreased, significantly. So, the highest biomass (1474.33 kg.ha-1) and grain yield (474.15 kg.ha-1) were obtained in hard dough stage and the lowest amount of the mentioned traits were obtained in soft dough stage.
