The study aimed to investigate the effect of different densities of M.persicae and T. tabaci on the predatory ability of the predator O. albidipennis and determine the preference for one of the two prey, in addition to assessing the in vitro predator's efficiency in reducing the number of aphids on the carrot plant. The results indicated that the rates of predated adult and nymph thrips were significantly higher than that of predated aphids. The highest rate of predation for nymphs and adults thrips was 33.2 and 25 preys per day, respectively, at a density of 60prey/container, while the highest rate of predation of adults and nymphs of aphids was 19 and 13.2prey/day, respectively, at a density of 60prey/container. The food preference experiment showed that the adults of the predator O. albidipennis feed on the immature stages thrips and aphids when introduced together and have no clear preference for one of the prey. The results of evaluating the efficiency of predator adults on reducing different densities of aphids showed that the predator was effectively able to reduce the population increase of aphids when the insect densities were 10, 20 or 30 insect. however, the predator was not effective when introduced to aphids at starting density of 40, no significant difference was found due to predator presence or absence as the aphids population density were 118.4 and 135.2 insects/cage after four days, respectively.

A field experiment was carried out during the summer season of 2019 in one of the fields of Al-Tahiniah village - Al-Mahanawiya district which is 36 km away from the Diwaniyah governorate center, to study the effect of Azola, phosphate and nitrogen fertilizers and the interactions between them on yield components, yield and grains quality of the rice grown in water logging conditions. The experiment was arrangement as factorial experiment according to Randomized Complete Blocks Design (RCBD) at three replications. The experiment included three factors, the first factor included the application of Azolla (Azolla pinnata L.) at 20 tons ha-1 and the control treatment (without application of Azolla), while the second factor included application three levels of phosphate fertilizer (21, 42 and 84 kg P ha-1) as well as the control treatment (without application of phosphate fertilizer), whereas the third factor included application two levels of nitrogen fertilizer (92 and 184 kg N ha-1) as well as the control treatment (without application of nitrogen fertilizer). The results showed that the application of Azolla pinnata L. achieving the highest results of the number of panicles per plants, number of grains per panicle and grain yield by 30.30, 6.37 and 7.80% respectively compared with control treatment that achieved the lowest results for all traits respectively. Also, the application of phosphate fertilizer at half recommended amount (42 kg P ha-1) was significantly superior and gave the highest results of the number of panicles per plant, number of grains per panicle and grain yield with a significant increase of 35.29, 4.76 and 7.55 respectively compared with control treatment. In addition to, the application of nitrogen fertilizer at the recommended amount (184 kg N ha-1) had the highest results of the number of panicles per plant and number of grains per panicles by 48.29 and 5.75% respectively, without significant difference on the application of nitrogen fertilizer at half the recommended amount (92 kg N ha-1) which had the highest mean of the grain yield by 4.94% compared with control treatment which had the lowest results for all traits respectively. The interaction between the application of Azola and the levels of phosphate fertilizer, application of Azola and the levels of nitrogen fertilizer, application of phosphate and nitrogen fertilizers as well as the tri-interaction between three factors had significant effect in all the studied traits except the weight of 1000 grains. We can concluded that the application of Azolla pinnata L. reduced the amounts of phosphate and nitrogen fertilizer by 50% of Recommended amounts and led to improvement the yield and yield components of rice in addition to grain rice quality.

The study focuses on rainfall, number of rainy days and droughts, on an annual time step basis, over the period (1940-2019). Each parameter is analysed by the average behavior of 1,817 variables representative of 23 semi-arid wilayas. The approach helps to characterise the rainfall climate of cereal-growing regions, where production and yields per hectare are unstable for decades.The average rainfall, estimated at 423 mm, shows a cyclical evolution, reflected by a change in averages: 430, 405, 440 mm. These averages reproduce two relatively rainy cycles (1940-1970) and (2000-2019), separated by a dry cycle (1970-2000). The frequency of cyclical rains, however, shows that rains above 400 mm remain less dominant over 79 years. The averages of observations decrease progressively with the increase of the quantities of rains, that is to say, percentages that do not exceed 14, 13 and 9%. These characteristics underline interannual droughts, which fluctuate between 0.8 and -2.5, showing a progressively decreasing number of rainy days. The results obtained do not seem to explain all the variations in cereal production and yield. However, the correlation coefficients below 35% reflect the efficient use of rainfall during the crop growth cycle, which is subject to other production factors.

The approach adopted for the assessment of Kodiat Rosfa dam water quality, through the respective indexes WQI and IWQI, allowed to highlight the quality of its waters for the intended uses. Indeed, the physicochemical analyzes of the months of February, March, July and December, corresponding to the monthly precipitation and regularized volumes of 2013, 2014, 2015 selected,  revealed that 08 samples out of 12 have a WQI within 50 to 100, and 04 samples with WQI lower than 50. This classified the dam waters as good to excellent for consumption. Nevertheless, the results of IWQI index used to assess the quality of dam water Kodiat Rosfa for irrigation show that 7 samples out of 12 present an IWQI within 55 to 70 and 5 samples with IWQI lower than 55. These waters are characterized by moderate (MR) to high (HR) restriction.

The primary objective of this study is to use a better method for rainfall mapping in areas with low density rain gauge networks. Secondly, to identify and study hydro-climatic change in the semi-arid high plains of eastern Algeria on the basis of a comparative mapping approach. The latter concerns the annual rainfall map produced by the authors of this paper for the period studied (1986/2016) and the annual rainfall map for the period 1913/1938, prepared by Chaumont and Paquin (1971). The results of this analysis show that isohyets between 300 mm and 350 mm cover a large part of the study area, they occupy an area of 14444 Km², followed by isohyets between 200 mm and 300 mm with an area of 5298 Km². In addition, the comparative analysis between the periods showed that hydro-climatic change was clear for the 200 mm, 300 mm and 400 mm isohyets, whereas there are no major changes for the 500 mm and above isohyets. Data processing based on a combination of statistical and geostatistical analysis (multiple linear regression and kriging) has once again shown the value of taking into account other parameters in the design of rainfall maps, such as geomorphological and geographical parameters.

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 .

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
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.

Abstract: The experiment has been conducted at the poultry farm of Al-Qadisyah University, College of Agriculture, Department of Animal Production , for the period 24/11/2018 till 10/4/2019 by using 80 hatching chicks which belong to 20 dams and 5 sires, each sire includes 16 chicks. Four chickens are put with each sire, the first sire( Leghorn) crossbreeding with dams of Lohmann , the remaining sires are local cocks ,with five Lohmann hens. The chicks of each sire divided into two replicates ,each replicate contains 8 chicks , the experiment continues for 42 days of age.
The experiment aims to study the effect of sire groups on growth traits (weight at hatching , weight at 42 days of age , weight gain and daily weight gain ) Also , the effect of sire on weekly consumption feed , in addition to estimate the heritability for previous traits and the genetic correlations among these traits.
The results can be summarized as follows :
1- The overall means of weight at hatching , weigh at 42 days of age , weight gain and daily weight gain are 34.572 , 354.898 , 320.327 and 7.627 gm respectively , the sire groups appear significantly (p0.05) effect on weight at hatching and weight at 42 days of age and weekly consumption seeds.
2- Sex has significantly (p0.05) effect on weight at hatching and weight at 42 days of age.
3- The conversion feed ratio is 3.462 gm consume feed/ gm of meat.
4- The estimated values of heritability for weight at hatching weight at 42 days of age , weight gain and daily weight gain and daily weight gain , are 0.332 , 0.55 , 0.55 and 0.56 respectively.
The values of genetic correlation between weight at hatching and weight at 42 days of age and between weight at hatching and weight gain are 0.98 and 0.58 respectively.

The study aims to determine the effect of the cultivated area and the purchase price on the production of rice in the province of Al-Qadissiya - Iraq for the period (1990-2014). Johansen and Juselius method is used to test the co-integration between the variables. Vector Error Correction Model (VECM) is employed to determine the direction of the causality between production and price of rice, as well as between the production of rice and the area cultivated in the short and long run. The analysis of the results shows that there is a co-integration among the variables, and the direction of the relationship is a directional move from cultivated area to production of rice, and from price to production of rice in the short and long run. The study recommends to expand the cultivated area along with maintaining the farm and not to converted to other crops, in addition of determining the purchase price of the crop at the beginning of the agricultural season to ensure a good income for farmers in order to motivate them to increase production.

The Effect of Insecticide Vapona ( Nogos) on Pseudomonas aeruginosa in AL-Qadisiya District Fields

Al-Qadisiyah Journal For Agriculture Sciences, 2012, Volume 2, Issue 1, Pages 108-115
DOI: 10.33794/qjas.2012.47735

This study includs the determination of the effect of the insecticide
(Nogos) on Pseudomonas aeruginosa isolated from the rizosphere of Vicia
faba in the fields of AL-Qadisiya district at the range of 0.1,0.3 0.5 ppm
concentration where the 0.5 ppm concentration represents the initial
concentration in the fields .
The results show that the numbers of P.aeruginosa reached 5.8×107 in
treatment control, but the number decreases to 6.4×106 with Nogos in 0.3
ppm and the numbers increased to 1.2×108 in 0.1, 0.5 ppm .
The results show that P. aeruginosa are able to convert this insecticide to
other compounds in the laboratory.
