A field experiment was carried out in the province of Najaf - al ashraf using two types of blue-green algae( Anabaena circinalis and Oscillaoria lymentica) which have been isolated and diagnosed in the laboratories of the department of plant protection / ministry of agriculture in Iraq with the compost( palm fronds ) manufacturer locally and by 1 ml : 10 g of organic matter within one month of cuddling and using a single level of humidity is 1 : 2 (water : organic matter). Randomized complete block design RCBD to see the effect of use it as a single or mix in the productivity of rice crop Yasamin cultivar where it was noted that it is equipped with a dynamic composting of organic matter leads to the analysis of organic material and increasing the nitrogen content to moss 32.76 % with Anabaena and 19.72 % with mixture of algae. It was also observed superiority of the treatment (5) Anabaena with 25% of the chemical fertilizer, treatment (4) Anabaena with 50% of the chemical fertilizer which is not differ with the treatment (2) full recommending fertilizer and treatment (9) compost with 50% of the recommendation fertilizer, which gave seed weight 695 g / m2 and 694 g / m2 , respectively, compared with 754.7 g/m2 and 730 g/m2 respectively, Weight of 1000 also gave the seed of 27.64 g and 27.58 g, respectively, compared with 754.7 g and 730 g, respectively the length of the deltoid was 25.23 cm and 24.70 cm, respectively, compared with 25.37 cm and 25.30 cm respectively and it was noted an increase in the biological yield gave 15.88 tons / h and 15.84 tons /h, respectively, compared to 16.50 tons/h and 16.13 tons /h. Also it was noted an increase in the length of plant in treatment (4) Anabaena with 50% of the fertilizer recommendation which is not differ with the full treatment of recommendation fertilizer and the treatment 9 of compost with 50% of the recommendation as fertilizer gave 110.6 cm compared to 110.9 cm and 110.1cmrespectively, as for the dry weight observed increasing of algae treatments (4) treatment Anabaena with 50% of the recommendation fertilizer ,(5) treatment Anabaena with 25% of the recommendation fertilizer and (7) treatments (algae mixture with 50% of the fertilizer recommendation) which is not differ from full recommending fertilizer (2) treatment and (9) treatment compost with 50% of the recommendation fertilizer, was given 890 g 893 g, 890 g, respectively, compared to 896 g and 883 g, respectively.
We conclude that the use of the way with bio- organic and algal fertilizer in alone or mixture increase in productivity of growth ,biological yield and reduces the use of chemical fertilizer for a healthy quotient of consumers in food consumption.
This study was conducted in a lath house, Dept of Hort. and Landscape, College of Agricultural Engineering Sciences, Univ. During the 2021 growing season, Baghdad will investigate the influence of organic and Biological fertilizers on three Citrus rootstocks' growth and leaf mineral content. The first factor is the addition of liquid organic fertilizers Vit-Org (O) at three levels without addition (O0), soil addition at 10 ml.L-1 (O10) and soil addition at 20 ml.L-1 (O20). The second factor is the addition of nitrogen-fixing bacteria without addition (N1), add 30 ml.Transplant-1 of Azotobacter chroococcum (N2) and add 30 ml.Transplant-1 of Azospirillum brasilemse (N3). The third factor is three citrus rootstocks: sour orange (R1), R

The present work was conducted in the fields of Al-Sewarah and Kurkok stations which belong to the State Board of Agricultural Researches, Ministry of Agriculture, Iraq during the growing season of 2018. The goal of the study was to test the effects of the application of cyanobacteria (Anabaena circinalis and Nostoc commune) alone or in combination with reducing the dose of chemical fertilizers (CFs), which consisted of diammonium phosphate (DAP) and urea (46% nitrogen), on growth, yield and yield components of wheat cv. IPA99. Application of 50% and 100% of CFs without cyanobacteria as well as control (without cyanobacteria and CFs) were also included in this study for comparison.

Iraq is a developing country with a high population. In Iraq, heavy metal and metalloid contamination has resulted from both industrialisation and environmental sources, providing serious health risks to the local population. We conducted one of the most comprehensive analyses on the current state of Iraq's heavy metal and metalloid pollution in this paper, which included water, soil, paddy, and rice. A study was carried out to determine the concentration of heavy metals including Lead (Pb), Cadmium (Cd), Iron (Fe), manganese (Mn), Cobalt (Co), Magnesium (Mg), Aluminum (Al), and Copper (Cu) of 39 irrigation water samples, 75 soil samples, 75 paddy samples, and 75 rice samples in two Iraqi governorates (Diyala , and Salah al-

This research develops a new method based on spectral indices and random forest classifier to detect paddy rice areas and then assess their distributions regarding to urban areas. The classification will be conducted on Landsat OLI images and Landsat OLI/Sentinel 1 SAR data. Consequently, developing a new spectral index by analyzing the relative importance of Landsat bands will be calculated by the random forest. The new spectral index has improved depending on the most three important bands, then two additional indices including the normalized difference vegetation index (NDVI), and standardized difference built-up index (NDBI) have been used to extract paddy rice fields from the data. Several experiments being
