The objective of this study was to evaluate the productive performance of sunflower plants irrigated with different levels of domestic treated sewage and groundwater well with different doses of nitrogen. It was used randomized blocks design in split-split plots with four replications. In the plots, we evaluated the effect of two types of irrigation water, in the subplots we evaluated the five irrigation levels expressed as 25, 50, 75, 100 and 125% of the Class A pan Evaporation (CAE), and in the sub subplots, we evaluated the effect of four different doses of nitrogen (25, 50, 75 and 100 kg ha-1). The irrigation of sunflower with domestic sewage produced greater yield potential of grain and oil. The use of water from treated wastewater can replace up to 50 kg N ha-1 without affecting productivity. It is recommended for the commercial production of sunflower the use of treated sewage water with irrigation depth relative to 100% of CAE (296.64 mm) and nitrogen of 25 kg ha-1.

Unconventional water regards as an important source to ensure the water requirements for many Arabic countries, particularly in Libya which is suffering scars of irrigation water for some kinds of crops. So many treatment plants have been constructed in the main cities, but the reuse of treated water is still limited due to their environmental effects, whereas the reuse of these water needs an excess of researches and tests to satisfy the standards of recycling. The objective of this study is the seeking for aother new sources of unconventional water such as treated sewage water, grey water, and desalinated water to insure the water requirements. The studied samples have been collected from sewage water to perform the the different tests of evaluation this water, such as physical, chemical and biological measurements to determine the nature of water after treatment process. In the spotlight of the obtained results from laboratory tests in Tobruk treatment plant, it is clear that reveal a high efficieny of treatment from pollutants that can enable us for recycling and reuse this water for irrigation. Consequently, we recommended to spotlight on these great quantities of these waters to exploit in different purposes that regarded as a renewable source of water.

An experiment was conducted at the Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh, Bangladesh to evaluate the influence of fertilizer-N on biochemical characteristics, nutrient accumulation and yield of potatoes during the period from November 2002 to March 2003. Two varieties, namely Cardinal and Diamant and five levels of N viz. 0, 100, 125, 150 and 175 kg ha-1 were applied in a factorial randomized complete block design with three replications. The results indicated that the biochemical characteristics, nutrient concentrations, yield components and yield were significantly influenced by the different levels of N. The nitrate reductase activity, chlorophyll content, total free amino acid showed positive linear relationship with different doses of N-fertilizers. The highest tuber weight and nitrogen accumulation were found from the plants which received 150 kg N ha-1. Application of 150 kg N ha-1 resulted in best biochemical characteristics, nutrient uptake, yield and yield components of potato varieties- Cardinal and Diament.

The tomato is considered the second vegetable of economic importance in Brazil and for the success of its cultivation, depends to a large extenton the use of quality seedlings, since a well formed seedling will give rise to a plant with high productive potential. Adequate water availability is important to produce good seedlings, but failing that, commercial polymers inserted into the substrate can be used. The objective of this work was to study the effects on the development of cherry tomatoes in different doses of polymers applied to the substrate and different levels of irrigation until the transplant phase using fuzzy modeling. For this study, we used data from an experiment conducted at the Faculty of Technology of Presidente Prudente.The input variables of the developed system based on fuzzy rules were Polymer and Irrigation, and for both were defined 5 fuzzy sets. The output variables wereshoot length (CPA), root length (CR) and seedling dry mass (MSM). For the SBRF output variables, 5 fuzzy sets were also defined. The analysis of the effects of polymer doses and irrigation levels on tomato seedlings was performed using three -dimensionalgraphs and contour maps of the output variables. This analysis allowed us to conclude that, for irrigation levels below the maximum (daily irrigation), the use of 2 grams of polymers refers to the best conditions of the variables shoot length, root lengthand dry mass of the seedling.

In this work, the pomological characteristics, phenolic composition, and chemical contents modification in response to treated wastewater (TWW) irrigation was studied on olive fruits. The experiment was carried out during two successive years (2016/2017) on olive trees (cv. Chemlali). Three irrigation treatments were adopted and two TWW irrigation levels were applied (T1: 20% ETc; T2: 40% ETc; CT: Control Treatment (rainfed condition)). Results show that TWW irrigation leads to increased fruit fresh weight and water content, whatever the level applied. In addition, fruit oil content remained unaffected by TWW irrigation. Moreover, this agronomic practice preserves some phenolic compound contents like verbascoside, therefore fruits nutritional value. A positive feature was then observed following TWW irrigation. In fact, oleuropein, tyrosol, luteolin-7-glucoside, and pinoresinol amounts were enhanced in treated olive fruits. On the other hand, TWW irrigated trees with a level of 40% ETc (T2) produced olive fruits richer in Mg and K than those cultivated in rainfed conditions (CT). Fruits Zn, Mn, and Pb contents decreased as a result of olive trees TWW irrigation.

An experiment was conducted to find out the influence of three irrigation levels (no irrigation, one irrigation and two irrigation) on four mustard varieties (Tori- 7, BARI Sharisha-6, BARI Sharisha-9 and BARI Sharisha-8). The non-irrigated plots had highest aphid population (34.96/plant) and lowest (11.16 aphids/plant) in two irrigation. The variety BARI Sharisha-8 showed lowest (5.34 aphids/plant) aphid infestation and its yield was highest (2.05 ton/ha). Interaction effects indicated that the crop escaped from the aphid incidence in the variety BARI Sharisha-8 irrigated 2 times and produced highest yield (2.37 ton/ha). The differences in the aphid population at three irrigation levels affected the yield contributing characters and it was negatively correlated (correlation coefficient value ‘r’ ranged from -0.91 to 1.0).Bangladesh J.

The applying of antibiotics in animal husbandry leads to the spread of antimicrobial resistant pathogens among domestic animals, which are subsequently transmitted to humans through the food chain. The analysis of literature data on the results of the study of phytochemicals of plant origin in the form of essential oils of medicinal and aromatic plants as one of the possible alternatives to feed antibiotics is presented. Such additives should reduce the incidence of animals by inhibiting pathogenic microflora, provide the animal with a larger amount of energy and nutrients by reducing the bacterial load in the intestine, reduce internal inflammatory processes by improving the immune system, and should be economically beneficial. A review of scientific studies showed that essential oils do have bactericidal properties, but their effect on the productive performance of animals still requires further research. Differences in animal productivity when using essential oils may be due to researchers using different doses, different test conditions (especially climatic conditions), and possible synergistic and antagonistic properties of essential oils with other feed substances.

The effect of irrigation and bio-stimulant (ComCat) applications on fruit quality parameters at the ‘Rubygem’ strawberry variety was investigated. The amounts of irrigation water applied were 0.50, 0.75, 1.00 and 1.25 times of water surface evaporation measured Class A pan placed over the crop canopy and the corresponding regimes were denoted as IR50, IR75, IR100 and IR125. Furthermore, bio-stimulant is applied four times with three weeks interval, approximately two months after planting. Applications of bio-stimulant were not efficient on examined parameters. Decreasing of the irrigation levels were significantly increased TSS and sugar/acid ratio which affects the fruit taste. The highest TSS and sugar/acid ratio was determined at IR50 plot with 9.42% and 21.7 values, respectively. However, fruit weight was significantly decreased except of IR100 plot. Moreover, deficient irrigation (IR50 and IR75) may cause a decrease at fruit weight. Recently, it could be crucial strategy to improve sugar and sugar/acid ratio which were prominent for consumers on the eating quality. Also, improving fruit taste with bio-stimulant application at optimum irrigation level (IR100) without any decreasing of fruit weight was determined.

The study was conducted in the poultry field in the Animal Production Department/ College of Agriculture and Forestry/ University of Mosul, for the period from 18/ 2/ 2020 until 13/ 4/ 2020. The experiment aimed to study the effect of replacement different levels of sesame meal (SSM) as a protein source to replace soybean meal (SBM) on the productive performance and reproductive of laying quail, 360 quail birds (240 females and 120 males) were used, at the age of 49 days, distributed randomly into five treatments, each treatment with eight replicates, ( 9 birds in each replicate 6 females and 3 males). The treatments were as follows: the first was the control (0% SSM), the second, third, fourth, and the fifth replaced SSM by SBM with level (25, 50, 75 and 100%) respectively, feed and water was ad libitum during the trial period of 8 weeks. The results of the statistical analysis showed there is a significant statistical difference at a level (P≤0.05) in the fifth treatment (100% SSM) as compared to control and other treatments in total egg number, average egg weight, total egg mass, Hen day egg production percentage (% HD), feed intake, feed conversion ratio, fertility, and hatching percentage of total eggs, average weight of hatched chicks, and a significant increase in the embryo mortality. The results also showed a significant decrease at a level (P≤0.05) in the feed intake for the fourth treatment (75% SSM) compared to the control, while no significant differences were observed for the other treatments in all the studied traits. The results of this study showed the possibility of using sesame meal as a protein source at (75%) to replace soybean meal in laying quail bird diets.
