The experiment was conducted in the horticulture station located in Al -Mahaweel / Babylon during the period from 09.15.2012 to 15.05.2013 to study the response of sour orange (Citrus aurantium L.) to seedlings compost extracts. The experiment contained two factors. The first is types of composed extracts (wheat straws, rice residues and mushroom culture residues), the second is concentrations (0, 100, 125 or 166.6) g.L-1 of each extract. Results showed a significant increase in some of the studied parameters plants height,stem diameter, total number of branches, leaf area, leaves content of total soluble carbohydrates and chlorophyll As a result spraying extracts of compost and the concentrations, as well as interaction between the two treatments significant increase to spraying extract mushroom culture residues and the concentrations 166.6 g.L-1 as compared to the control treatment (water only).نُفِذَتْ التجربة في محطة البستنة في قضاء المحاويل / محافظة بابل للمدة من 15/9/2012 إلى15 /5/2013 لدراسة إستجابة شتلات النارنج Citrus aurantium L. إلى الرش بالمستخلصات العضوية المتحللة. اشتملت التجربة على عاملين يمثل العامل الأول: مستخلصات الأسمدة العضوية وهي: مستخلص مخلفات قش الحنطة ومخلفات بوه الشلب ومخلفات زراعة بيئة فطر المشروم (عيش الغُراب), وأما العامل الثاني: تراكيز مستخلصات الأسمدة العضوية وهي أربعة مستويات 66.6,125,100,0 غم.لتر1-. أظهرت النتائج حدوث زيادة معنوية في بعض المؤشرات المدروسة ارتفاع الشتلة, قطر الساق, عدد الأفرع الكلي, المساحـة الورقيـة, محتوى الأوراق من الكربوهيدرات الذائبة الكلية, محتوى الأوراق من الكلوروفيل الكلي نتيجة الرش بمستخلصات الاسمدة العضوية وبمختلف تراكيزها والتداخل بينهما حيث تفوقت معاملة الرش بمستخلص سماد بيئة فطر عيش الغراب والتركيز166.6غم.لتر 1-قياسا مع الرش بالماء فقط (معاملة المقارنة).

Research was conducted in the laboratories ofAgriculture college/Kufa University, It was found that exposing fungi Cladosporium cladosporioides and C. oxysporum to a series ofstress saline 155 dS.m-1 significant superiority in the radial growth compared to Fusarium pseudonathophillium and F. nygamai. While in series 165 ds.m-1 explained to superiority radial growth ofC. cladosporioides compared with Aspergillus clavatonictus and A. candidus. Whereas exposing series salt stress 175 dS.m-1 gave A. homomorphus superiority compare with A. clavatonictus , C. cladosporioides , C. oxysporum , F. pseudonathophillium and F. nygamai in radial growth. When exposing the fungi to a series ofsalt stress 155 and 165 dS.m-1 C. cladosporioides has showed superiority in sporulation compared to the other isolated fungi, whereas the level ofsalt stress 175 ds.m-1 indicated the superiority in sporulation ofA. niger compared to all isolated fungi except C. cladosporioides.

The study aimed to evaluate the activity 0f the allelopathic exudates ofanise (Pimpinella anisum)،pea (Pisum sativum)،garlic(Allium sativum)and onion(Allium cepa) plants،in the growth and Pathogenicty ofFusarium oxysporium f.sp lycopersici (F.o.l.) and the ability of Trichoderma harzianum (T.h.) as a bioagent in the control and the activity of the extraction ofshoot and root ofanise and garlic plants on The growth and sporulation ofthos two fungi. The pathogenicity test of F.o.l. showed the seed decay oftomato was 100% compared with 0.0% in the T.h. treatment .The results appeared the root exudates ofanise and garlic reduced the radial growth of F.o.l. to 0.49 and 1.01 cm respeetively ،whereas the pes treatment promoted the growth of F.o.l. to 1.83 cm compared with 1.50 and 1.51 cm in control treatment ’ while the root exudates ofgarlic increased the radial growth of T.h. to 1.12 cm compared with 1.02 cm in the control. The root exudates of 50 seed ofanise and 50 gorlic bulb reduced the soft biomass weight of F.o.l. to 16.60 and 16.05 gm compared with 18.88 and 18.45 gm in the control respectively ،whereas the above treatment increased the weights in T.h. to 8.89 and 7.79 gm compared with 7.10 and 6.23 gm in the control. The root exudates ofanise plnt for growing 10 d increased the shoot length oftomato to 12.67 cm comeared with 8.8 cm in the control and root to 9.43 cm for 15 d in above treatment compared with 7.00 cm in the control increased the followring setting to 92.70 % and The in teraction’ increased The productivity to 9.72 and 9.16 kg in anise and garlic treatments respectively compared with 7.83 kg in tomato plant alone.

A field experiment was conducted in two locations, the Al-Mahanawyie district/ Abo-Gharaq in the province ofBabylon and in Al-Sahla district/Kufa in the province ofAl Najaf Alashraf in the growing season of2012-2013 to study the response ofthree cabbage cultivars to spraying with compost extract ofdate palm leaves. The experiment included 12 treatments due to the interaction between three cultivars ofcabbage (Copenhagen Market , Ruby Perfection and Tropicana) and four concentration 0, 25, 50 and 75 ml.L -1 oforganic fertilizer extracts. The experiment was Randomized Complete Block Design (RCBD) with three replications .Results can be summarized as following : Results showed that cv. "Tropicana " had significantly the highest plant leaf number, leaves content ofN, head weight, total productivity and head quality characteristics (protein and carbohydrate percentages), while "Copenhagen Market" cv. was significantly eminent in terms of K percentage only compared to cv. "Ruby Perfection" which gave the lowest values for the above characteristics. Spraying results revealed that all concentrations ofcompost extract had significant effects on the above characteristics compared to spraying with distilled water which gave the lowest values. Interaction between cv. and spraying with compost extract showed in significant where (50 ml.L-1 with Tropicana) resulted in the highest values ofplant leaf number, leaves content ofN, head weight, total productivity and head quality characteristics protein and carbohydrate percentages 66.87,67.39 leaf plant-1 and 4.07% and 2.83,0.97 kg and 47.41, 26.90 Ton.h-1 and 25.50,23.58% and 2.88,2.76% for both locations, respectively except percentage ofN that was the highest in location 2, the interaction of(50 ml.L-1 ×Copenhagen Market) had significantly the highest percentage ofK(3.90,3.84%) for both locations, respectively compared to interaction of(distilled water with Ruby Perfection) which gave the lowest values ofplant leaf number, leaves content ofN, leaves content ofK, head weight, total productivity and head quality characteristics protein and carbohydrate percentages 44.87,40.42 leaf plant-1 and 2.22,1.47% and 2.45, 2.27% and 1.55,0.22 kg and 23.96,16.61 Ton.h-1 and 15.61,14.19% and 1.72,1.56% for both locations, respectively.

An experiment was conducted during the Agricultural winter seasons of2011/2012 in unheated plastic house at the College ofAgriculture. Basrah University. The aim was to study the effect ofspraying with bio hormone (Kelpak) and Vit. Org. on growth and yield oftwo cucumber vars."Sara" and "Saif ". The experiment included eight treatments which is the combination resulted from the interaction between spraying with and without for both Kelpak and Vit. Org. and two varieties ofcucumber. Results can be summarized as follows : Sara plants gave significant increases in total leaf number/ plant, decrease days for first inflorescence opening, total flower number/ plant, total fruit number/ plant, fruit weight(103.4g), fruit yield/ plant(3.133kg) and plastic house productivity (1349.0 kg). Whereas, Saif plants gave significant increases in chlorophyll content ofleaf only. Plants sprayed with bio hormone ( Kelpak) gave significant increases in plant height, chlorophyll content, decreased days for first inflorescence opening, total fruit number/ plant, fruit length, fruit diameter fruit weight(101.3g), fruit yield/ plant (3.690kg) and plastic house productivity( 1307.0 kg). Whereas, plants with out spraying gave significant increase in carbohydrates content. Plants sprayed with Vit. Org. gave significant increases in carbohydrates content, decrease days for first inflorescence opening, and fruit set. Total flower number/ plant. total fruit number/ plant, fruit diameter, fruit weight(104.3g), fruit yield/ plant (3.106 kg) and plastic house productivity( 1366.0 kg), whereas, plants with out spraying gave significant increase in tota soluble chlorophyll content. The interaction between the studied factors gave significant increases in all studied parameters.
