  Considering the limited resources of water and dominant draughts, deficit irrigation is an important strategy to obtain the product in water shortage conditions. Deficit irrigation aims to produce more products from less water. Therefore, an experiment was conducted in order to evaluate the impact of deficit water and poultries manure on the performance, performance components, and water use efficiency of potato in Jiroft. The experiment was conducted in strip-plot form in the complete random blocks design with three replications. Three water levels as a main factor including 100, 75 and 50 percent of plant water requirement and four manure levels as secondary factor including 0, 5, 10 and 15 Ton ha-1 were considered. The results indicated that different levels of irrigation and poultries manure on both water use efficiency and potato yield were (1%). Also, the impact of different levels of irrigation and the poultries manure on the weight of potato tuber is significant. Moreover, the interaction of the irrigation regime and poultries manure on water use efficiency and potato yield was not significant. Furthermore, the effect of different levels of irrigation and poultries manure alone on the plant height was not significant, but their interaction was significant. Though the effect of different irrigation levels on the percentage of dried material of tuber was not significant, the impact of different levels of poultries manure, and the interaction of irrigation regime and poultry manure on tuber dry matter was significant.

  Background and Objective: Many of the antibiotics used in poultry farms are excreted in their feces. This waste is used as organic fertilizer in agriculture and causes the release of animal antibiotics in the environment. These compounds may increase the antibiotic resistance of microbial populations or damage plants grown in these soils. The aim of this study was to determine the effect of aerobic and anaerobic poultry manure composting on the amount of enrofloxacin and ciprofloxacin antibiotics in poultry manure at two levels of high and low concentration and compare them with each other. Method: Two samples of fresh broiler chicken manure were prepared after the end of the chicken treatment with antibiotic enrofloxacin. The two samples contained two levels of high and low concentrations of Enrofloxacin and Ciprofloxacin. The composting of chicken manure was done using a completely randomized design with 4 treatments of 1- aerobic treatments at a low concentration,              2- aerobic treatments at high concentration 3- anaerobic treatments at low concentration 4- anaerobic treatments at a high concentration in five replicates in 75 days. Samples were prepared at specific intervals and the concentration of Enrofloxacin and Ciprofloxacin was measured by HPLC method. The obtained data were fitted with the first-order kinetic equation and the half-life of the antibiotic degradation was calculated. Findings: The results showed that at the end of the period, in treatments 1 to 4, 54.2%, 64.3%, 65.3% and 69.7% of the Enrofloxacin and 41%, 57.8%, 57.8% and 61.8% Ciprofloxacin remained. The correlation coefficient (R2) obtained from the fitting of the first-order kinetic equation in treatments (from 0.71 to 0.92) showed that the data fit well with this equation. The half-life of the Enrofloxacin degradation was obtained between 96.27 and about 150.68 days. The half-life of degradation for Ciprofloxacin was also found to be between 57.28 and 117.48 days. Discussion and Conclusion: Overall, the results showed that the process of composting reduced the concentration of antibiotics and prevented its entry into the environment. The rate and total amount of antibiotic degradation in aerobic conditions was higher than anaerobic. The rate of degradation of both antibiotics at a high initial concentration was lower than its rate of degradation at low concentrations. The rate of ciprofloxacin degradation was also higher than Enrofloxacin. The results of this study can help to create relevant laws and regulations in relevant institutions, in order to reduce the release of veterinary antibiotics into the environment. Manuscript profile

  To investigate the effect of nitrogen and phosphorus nutrients from organic and chemical fertilizers sources, on their efficiency in purslane, a field experiment based on complete randomized block design was conducted at the Research Farm of Shahrekord University in 201 More

  To investigate the effect of nitrogen and phosphorus nutrients from organic and chemical fertilizers sources, on their efficiency in purslane, a field experiment based on complete randomized block design was conducted at the Research Farm of Shahrekord University in 2014. Treatments were 13 t.ha-1 broiler litter (T1), 14.4 t.ha-1 broiler litter (T2), 39 t.ha-1 cattle manure (T3), 16.8 t.ha-1 cattle manure + 150 kg.ha-1 urea (T4), four chemical fertilizer levels equivalent to organic manure treatments, 260+86 kg.ha-1 urea +triple super phosphate, respectively (T5), 287+100 kg.ha-1 urea + triple super phosphate, respectively (T6), 260+200 kg.ha-1 urea + triple super phosphate, respectively (T7), 260+100 kg.ha-1 urea + triple super phosphate, respectively (T8) and control (T0). The results showed that T2 treatment produced 8345 kg.ha-1 of dry matter as compared with those of other fertilizer treatments (P<0.05). This indicate that nitrogen and phosphorus efficiencies in T2 treatment were significantly higher than other treatments (P<0.05). In the mean time, nitrogen efficiency in T5 and T7 were not significantly different. However, phosphorus efficiency in T2 (52.6 %) indicated significant difference as compared with the other treatments. Nitrogen physiological efficiency of treatment in T2 (35.02 kg.kg-1) and T8 (31.6 kg.kg-1), and also P physiological efficiency in T1 and T5 were not significantly different. As a whole, the higher N physiological efficiency and also physiological efficiency of phosphorus in broiler litter reflect the ecological role of organic manure application in the production of purslane. This can also help environmental protection, as well as preventing loss of resources and phosphorus accumulation in the cropland soils.   Manuscript profile

  To evaluate the effect of different levels of chemical and organic fertilizers on seed yield, its components and oil content of sunflower (Hybrid Iroflor), a factorial experiment based on randomized complete blocks design (RCBD) with 12 treatment and 4 replications was carried out at the Faculty of Agriculture, University of Maragheh during 2014 growing season. The first factor consisted of 3 levels of chemical fertilizer (C0: without using any fertilizer, C1: application of urea at the rate of 150 kg.ha-1 and C2:application of 75 kg.ha-1 urea + 50 kg.ha-1 super phosphate triple) and the second factor comprised of organic manure applications (O) with 4 levels (O0: without organic fertilizer, O1:animal manure application at the rate of 40 t.ha-1, O2: poultry manure application at the rate of 30 t.ha-1 and O3: %50 poultry manure+ %50 animal manure. Results showed that the highest chlorophyll index belonged to %50 nitrogen + 50% phosphorus plus poultry manure and nitrogen fertilizer plus poultry manure treatment combinations respectively. Applications of 75 kg N ha-1+ 50 kg P ha-1 and %50 poultry manure+ %50 animal manure treatment combination, resulted in grain yield increase by %42.02 as compared to the application of 75 kg N ha-1+ 50 kg P ha-1. Maximum kernel number per head was produced by interaction effect of chemical nitrogen fertilizer (150 kg N ha-1) animal manure (40 t.ha-1). Biological yield and harvest index were increased by %22.9 and %15.98 respectively, as compared to control and application of %50 poultry manure+ %50 animal manure. Highest percentage of grain oil (52.45%) was obtained by applications of 15 t.ha-1 poultry manure+ 20 t.ha-1 of animal manure, as compared to the control (30.13 percent). The highest oil yield (1784.57 kg.ha-1) was also belonged combined application of 75 kg N ha-1+ 50 kg P ha-1 and 15 t.ha-1 poultry manure+ 20 t.ha-1 animal manure. Thus, integrated application of organic and chemical fertilizers (75 kg N ha-1+ 50 kg P ha-1 and 15 t.ha-1 poultry manure+ 20 t.ha-1 animal manure) improved both grain yield and its oil content of sunflower more than their individual applications.

  یک آزمایش تغذیه­ای با هدف بررسی اثر وارد کردن بقایای نیشکر سیلو شده (ESCW) همراه با کود مرغی بر عملکرد قوچ­های یانکا در قالب یک طرح کاملاً تصادفی (CRD) به مدت 12 هفته (84 روز) صورت گرفت. بقایای نیشکر با کود مرغی به نسبت 3 به 1 مخلوط شده و به مدت 21 روز سیلو گردید. ESCW به عنوان بخشی از جیره جایگزین گردید. 16 قوچ یانکا (میانگین وزن 77/5±94/28 کیلوگرم در محدوده سنی 12 تا 18 ماهگی) در چهار گروه بر مبنای وزن بدن (گروه کنترل بدون ESCW (CG) و جیره­ها یا گروه­های تیماری (TG ها) که بخشی از جیره با 15 درصد (TG1)، 30 درصد (TG2) و 45 درصد (TG3) جایگزین شده بودند) تخصیص داده شدند. جیره­ها به صورت اختیاری همراه با آب آشامیدنی تمیز و نمک معدنی لیسیدنی در دسترس حیوانات قرار گرفتند. نتایج نشان داد که هیچ­گونه تفاوت معنی­داری بین میانگین تیمارها برای پارامترهای رشد وجود نداشته (05/0<P) ولی مقادیر ثبت شده برای TG3 (45 درصد) از نظر عددی در وزن زنده و افزایش وزن پایانی و میانگین افزایش وزن روزانه (ADG) بالاتر از سایر تیمارها بوده است. تفاوت ثبت شده در ماده خشک و خاکستر مصرفی معنی­دار بوده (05/0>P) و تفاوت ماده خشک، فیبر خام و قابلیت هضم ظاهری خاکستر بین CG و TG ها معنی­دار بوده است (05/0>P). از این مطالعه می­توان نتیجه گرفت که عملکرد قوچ­های یانکا با در نظر گرفتن 45 درصد ESCW در جیره قابل مقایسه با CG بوده و بنابراین کاربرد آن به عنوان جایگزین در طی دوره پروار بر مبنای حقایق تغذیه­ای مشاهده شده، توصیه می­گردد.

  In order to study the response of soil properties and sweet corn traits to different levels of organic and chemical fertilizers of nitrogen, a greenhouse­-­laboratory research was carried out as factorial based on a completely randomized design with three replications in Miyaneh Branch, Islamid Azad University. Experimental factors included poultry manure at three levels (0, 20 and 30 ton.ha-1) and nitrogen fertilizer at three levels (0, 100 and 200 kg.ha-1 from urea source). Results showed that application of poultry manure in soil increased soil pH, EC and organic carbon. Also, it had a significant effect on chlorophyll content, plant height and leaf area of sweet corn plants. Application of 20 and 30 ton.ha-1 poultry manure resulted in higher values of the studied traits. However, there was no ­significant differences between 20 and 30 ton.ha-1 poultry manure in most cases and so, application of 20 ton.ha-1 poultry manure was enough for achieving optimal sweet corn growth in greenhouse. According to the results, combined application of 20­ ton.ha-1 poultry manure and 100­ kg.ha-1 nitrogen from urea source could be recommended for optimum nitrogen supplying in sweet corn cropping system.
