This laboratory study aimed to evaluate the efficiency of two biological agents Beauveria bassiana (Bals) and Bacillus thuringiensis (Kursaki) and four chemical pesticides Levo 2.4 SL, Aster 20 SL, Difuse 450 SC, and Matrixine Plus EC on four important main pests that infect tomato plants. The pests studied were whitefly Bemisia tabaci (Hemiptera: Aleyrodidae), Meyrick Tuta absoluta (Lepidoptera: Gelechiidae), Sulzer Myzus persicae (Hemiptera: Aphididae) and Koch Tetranychus urticae (Acari: Tetraanychidae). The results show that the pesticide Matrixine Plus recorded the highest average of mortality of both larval and adult stages of all four pests. The average of mortality for adults and larvae of whitefly were 96.67% and 86.67% respectively. The average of mortality for adults and larvae of Meyrick was 93.33% for both stages, while the percentages for adults and larvae of Sulzer and Kotch were 96.67% respectively after seven days of exposure. The lowest averages of mortality were recorded for Antario on whitefly adults and for Difuse on whitefly (both (16.67%). Difuse caused the lowest average of mortality (26.67%) on Meyrick adults, whereas Antario caused the lowest average of mortality of 20% on Meyrick larvae. The results show also that Antario caused the lowest average of mortality of 23.33% on adults and 16.67% on larvae. Similarly, Difuse was recorded the lowest average of 20% on adults while Antario caused the lowest average of mortality of 26.67% on larvae after one day of treatment.

This study aimed at identifying the most important factors affecting bee honey production, by performing a comparative study for the economic efficiency and the technical efficiency, data were obtained from field sources in light of a random sample constituted a percentage of 5% taken from honey producers from 51 apiaries at the season of 2018- 2019. The research, in estimating economic efficiency and dividing its components into technical and allocative efficiencies, adopted the data envelopment analysis using the model of entry orientation in light of fixed and variable returns in checking the technical efficiency, and in light of variable capacity return  in checking allocative efficiency and cost efficiency, where we note that technical efficiency varied between (0.1-1) with an average of 27%, i.e. the sample is capable of increasing its production by 73% to reach the optimal volume, whereas we note that 96.3% of beekeepers are working with increasing capacity return. The technical efficiency, in light of the variation in capacity return, has varied between 0.5 minimum and 1 maximum with an average of 0.60, and that the apiaries which fell on the possible production curve were 12%. The economic efficiency on the other hand, reached an average of 0.46 and that means the bee breeding farms could achieve the same production level in light of costs reduction of 54%, i.e. capable of producing the current amount using only 46% of the economic resources, and this is attributed to the inadequacy of the allocative efficiency and the improper use of resources. The study recommended the use of amounts that realize the economic efficiency and, the redistribution of resources in a way that guaranties achieving the same level of production or more in light of costs reduction.

Half diallel crossing among five inbred lines of maize was  performed to estimate the combining ability effects and some genetic parameters. The crosses differed significantly for all the studied traits. Also, GCA and SCA mean squares were significant. The ratio GCA/SCA exhibited values under one indicating that non-additive gene action mainly controls the expression of all the studied traits. Inbred line 4 contributed significantly to the good performance of the hybrids for grain yield traits. Also, inbred line 5 exhibited desirable GCA effects for five traits and it seems to be promising. The crosses 2x4, 1x4 and 3x5 own highest mean and SCA effects for grain yield.

Glimpse of fish as perishable staple was reviewed. Fish is an important animal protein as it supplies good quality protein, vitamins and minerals. It is however highly perishable and spoils quickly, bad fish handling after harvesting, inadequate storage and processing facilities also contributes to fish spoilage in developing countries thus causing a lacuna between fish demand and supply, thus posing a great challenge to food security. Processing of fish facilitates its maximal use as for value-added fish products. Smoking is the preservation method most adopted in many developing countries to extend fish shelf life. Fish post-harvest loss come in different faces including: physical loss, quality loss and market forces loss all of which will lead to reduction in fish shelf life. Antimicrobial properties of plant extracts and proper packaging can extend fish shelf life. There in need to encourage women participation in fisheries subsector as their active role is essential to fighting poverty and ensuring food security within many households.

The quality of Heteroclarias with increased storage time using Quality Index Method (QIM) was evaluated. 140 live samples of Heteroclarias (average weight 230 + 7g) were used for the study. QIM was used to evaluate the key parameters in fish deterioration, twenty semi-trained assessors was used for the sensory evaluation. Data obtained were subjected to appropriate statistical tools using SPSS 16.0 version. Quality Index (QI) of Heteroclarias increases with increased post slaughter time when the fish was left at ambient temperatures (27 + 3°C) indicating decrease in fish quality with time. High correlation of (r=0.993) with a high coefficient of determination (R2=0.986) was obtained indicating that 98.6% of the variation in post slaughter time was explained by quality attributes; the regression equation was significant F(9, 130)=1080 (p<0.0001) indicating that it could be used for prediction and estimation of fish quality, the QI used in this study is therefore recommended to be used by relevant agencies for predicting fish quality.
Practical Applications :Fish is highly perishable despite its nutritional value, consumers becoming increasingly interested in the quality of fish they consume and the physical attributes of the fish is very vital for on the spot assessment of fish quality. This study provide quality index that could be used for prediction and estimation of fish quality using sensory evaluation.

In recent years, the development of agriculture in Algeria Southeast grew rapidly, which increased demand for agricultural products. Since this region has difficult agro-climatic conditions, irrigation seems to be a necessary factor to ensure optimal development and higher agricultural production. Like many irrigation techniques that are widely used, the performance of sprinkler irrigation is significantly affected by these conditions (mainly evaporation) which cause colossal water losses. The purpose of this study is to evaluate, through the experimental approach, the global losses of water caused by evaporation and wind drift on two irrigated surfaces in the arid zone of Touggourt. Here we propose adequate predictive equations and explore the effect of irrigated area on overall water loss values. These are measured on two blocks (A and B) the rain gauge method. Block A contains four lateral lines while Block B has only two. For both, each lateral line has four sprinklers. The results showed that the overall water losses of block A are about 24.13 to 50.46%, while those of Block B range from 29.52 to 49.5 %.Two obtained models are adopted for both blocks which can be useful tools for determining overall water losses in environmental conditions (air temperature, relative humidity and wind speed).Noting that when the irrigated area was larger, the water losses will be lass.

A field experiment was carried out in the field of the Faculty of Agriculture / University of Wasit located at a longitude 45° 50' 33.5"east and N 29° 36' 49.8" norths for the 2019 growing season, the soil texture was Sandy loam, to study the effect of types of mulching and irrigation systems on some physical properties of soil, growth and yield of maize. The study was carried as factorial experiment in RCBD design with three replications, the first factor was mulching (control, wheat straw, palm fronds, and black nylon), and the second factor was irrigation methods (basin, and furrow). Maize crop was planted on 20/7/2019, and harvesting was completed on November 20, 2019. The physical properties of the study treatments were measured before planting, mid-season and at the end of the season, which included bulk density, saturated hydraulic conductivity, and soil temperature. The growth characters of the maize were measured at 100% flowering, which include plant height, leaf area, weight of 500 grains, total yield, and water use efficiency. The most important results obtained can be summarized as follows:

The bulk density values at the beginning of the season were not significantly affected by soil mulching, as the values of bulk density rates were 1.23, 1.23, 1.23 μg m-3 for control, frond, and black nylon mulching compared to their pre-planting values 1.23 μg m-3. Whereas, there were significant differences in the mid-season in the bulk density values of the control treatment, as they reached 1.24 μg m-3. While the mulching of fronds and black nylon did not significantly affect the values of bulk density in the middle of the season compared with the values before planting. While it is evident that there was a significant effect mulching on the values of the bulk density of the control, frond, and black nylon mulching at the end of the season, which amounted to 1.24, 1.25, and 1.26 μg m-3, respectively, compared to their values before planting. Also, it is noticed that the values of the bulk density rates of straw mulching treatment decreased at the beginning, middle and end of the season, as the values were 1.21, 1.22, and 1.22 μg m-3, respectively, compared with their value before planting.
There was no significant effect of the two irrigation methods on the bulk density values at the beginning, middle and end of the season compared with the bulk density values before planting.
The presence of a significant effect of mulching on water conductivity, as the values of the water conductivity decreased compared to their values before planting, and became 2.68 x 10-3, 2.69 x 10-3, and 2.73 x 10-3 cm sec-1 for control, fronds, and nylon, respectively. While the treatment of straw mulching, the water conductivity values increased at the end of the season compared to their values before planting.
The presence of the effect of the irrigation method on water conductivity, and led to a decrease in the values of the water conductivity compared to its values before planting, as it reached 2.76 x10-3 - 2.75 x 10-3 cm sec-1 for the two irrigation treatments in basin and furrow, respectively.
A slight decrease in the temperature in the middle of the season during the months of September and October, and the decline continued until the end of the season in the month of November. The highest temperatures were recorded for the treatment mulched with black nylon and control, followed by the palm fronds and the lowest temperature for the straw mulch treatment. The irrigation method did not affect soil temperature during the crop growth stages.
The presence of a significant effect of mulching on plant height, the mean values of plant height were 184.05, 169.25, 149.6, 177.5 cm for control, straw, fronds, and black nylon respectively, as well as the absence of a significant effect of the irrigation method on plant height, the averages of the two methods of irrigation of basins and furrows were 169.95 and 170.25 cm, respectively.
The presence of significant differences between mulching treatments for the leaf area (4205, 5381, 4385, 3564 cm2 for straw, frond, control, and nylon mulching respectively. as well as, the absence of significant differences between the two irrigation methods on the leaf area.

DOI: 10.33794/qjas.2011.13954

Two experiments were conducted to assess the effect of different salt
levels and irrigation periods on some reproductive characters and chemical
properties of seeds of two peas ( Pisum sativum L.) cultivars; Alderman (tall
cultivar) & Little marvel (short cultivar).The experiment included the use
of drainage water at three salt levels: 2 , 4 , and 6 dsm-1 in addition to Al-
Diwaniya river water (1.4 dsm-1) as a control treatment and three
irrigation periods; 2 , 4 , or 6 days and the combination of the two factors.
The measurements included: number of pods per plant, pod length, number
of seeds per pod, fresh & dry weight of pods. Also some chemical properties
of seeds such as percentage of carbohydrate, proteins and fibers were
determined.
The results showed that salt levels of 4 and 6 dsm-1 levels and the prolong
of irrigation periods decreased significantly pods number and length in the
two cultivars. Seeds number per pod also decreased significantly by using
the 4 and 6 dsm-1 salt levels in Alderman while in Little Marvel cultivar all
salt levels caused such a decrease. Irrigation periods had no effect. All salt
treatments caused a pronounced reduction in fresh and dry weight of pods.
The protein and carbohydrates percentage in seeds were decreased also due
to the effect of all salt treatments in both cultivars while fiber percentage
increased only in Alderman cultivar. Irrigation periods had no significant
effect on the percentage of fibers, but lengthen the periods caused
significant reduction in proteins and carbohydrates content. The
combination of salts at 6 dsm-1 and irrigation every six days wasthe most
negatively effective treatment in all parameters studied.

A greenhouse pots experiment has been carried out using silty clay loam soil collected from Agronomy department field/College of Agriculture / University of Baghdad to study the behavior and effects of adding different phosphate sources and compost on wheat growth and soil content of phosphor in two stages of wheat growth (tillering& spikes formation). Wheat seeds Triticumaestivum L. are grown in 26/11/2013. Completely randomized block design (CRD) has been used and three mineral phosphate sources، phosphate rock PR (Ecashat region، Iraq),partial Acidulated phosphate rock PR (40 %) (PAPR) and Tri super phosphate (TSP) has been added at one rate (100 kg. p. ha-1 ) by mixing with soil before planting with two levels of compost 0 and 20 mega gram.ha-1 .The available soil phosphor and wheat growth parameters such as plant height , number of tillers , dry weight of vegetation and root plants and total dry weigh of plant are measured at tillering stage and spikes formation stage.
The results show that addition of the mineral phosphate sources and compost and their interaction show significant increases in soil available phosphor values. TSP addition gives the best significant differences followed by PAPR while addition of the phosphate rock does not give asignificant difference compared with the control at the two wheat growth stages. The percentages of increases in the average of the soil available phosphor are 32.7% , 12.81% at tillering and spikes formation stages in TSP and PAPR treatments respectively, and 46.7% , 42.8 % at tillering and spikes formation stages respectively when compost was added and 13. 61% at tillering stage and 11.4 %at spikes formation stage in interaction of compost with TSP. The addition of the mineral phosphate sources and compost and together show positive significant effects in most of growth parameters such as plant height ,tillers number and roots dry weight at spikes formation stage and total dry weight of plant , weight of straw at tillering and spikes formation stages .The TSP treatment is the best followed by PAPR treatment in increasing the last growth parameters compared with PR at which non-significant increases are recorded .
