Field experiment was conducted during 2007 in the experimental field of crop science Department/ Collage of Agriculture/ University of Baghdad, in order to identify the mechanism of compensation of cotton plant of Lashata Variety, with different levels of fruiting form removal in various time intervals and the effect of this factor on yield component. We use complete randomized block design with three replications. To compare the treatments: (control), 50% bud removal for one, two and three successive weeks, and 100% bud removal for one, two and three successive weeks, 50% flower removal for one, two and three successive weeks and 100% flower removal for one, two and three successive weeks, 50% boll removal for one, two and three successive weeks and 100% boll removal for one, two and three successive weeks. The 100% boll removal treatment for one, two and three successive weeks showed superiority in plant height, number of fruiting branches, leaf area, and boll weight, where as 50% of bud removal for one week showed high significance in, number of opened bolls about 83% increased, seed cotton yield in first picking that reached 3106.52 Kg/ha in rate 77% increased, the rate of earlierness in comparison with other both treatments, yield of both pickings that reached 3616.43 kg/ha in rate 87% increased as well as in the rate of earlierness that reached 82% in comparison with control treatment. The best treatment was 50% bud removal for one week in compensation and the least response was when 100% boll removal for three successive weeks in comparison with other removal treatment.

الخلاصة

Two field experiments were conducted with three replicates according to RCBD at the experimental field of Dept. of Field Crop Sciences – College of Agriculture – University of Baghdad during fall and spring seasons of 2001 to evaluate the effectiveness of herbicides; Imazamox, Atrazine, Bentazine, Isoxafutol, Propaquizefop and Clomazone; and their application rates on maize.The results showed that Atrazine (H69 and H68) at 3.2 kg.ha-1, after 60 days, was significantly superior to other herbicides by giving less weed population during spring and fall seasons (2.5 and 1.7 plant.m-2 respectively), while control treatment gave the highest average (16.2 and 11.8 plant.m-2 respectively). Thus in comparion with control, number of weed were reduced by 84.5% and 85.5% respectively. Using 0.192 kg.h-1 of Clomazon during spring season gave less average of weed number (3.4 plant.m-2) after 90 days, whereas the control gave higher average (25.1 plant.m-2), thus the weeds population were reduced by 86.46% in comparion with control. Herbicide behavior was different during fall season. Atrazine (H68) at 3.2 kg.ha-1 gave less weed population (2.9 plant. m-2) while the weed population of the control was 19.9 plant.m-2, so the weed population was reduced by 85.4. At harvest time, Isoxfotol at 105 kg. ha-1 resulted in less weed population (17.8 plant.m-2), while Atrazine at 2.4 kg.ha-1 resulted in less weed population during fall season (9.6 plant.m-2). From the results above, it was conclude that there were many differences in herbicide behavior in the percentage of weed number reduction after 60 and 90 days and at harvest time. These results confirm declining effectiveness of herbicide 90 days after sowing.

This experiment was conducted to compare the productive performance of three hybrids Fawbro , Lohmann and Hubbard broiler breeder in Iraq , using 18000 hens for each hybrid flock . Birds in each flock were divided into four groups ( 4500 hens / group ) and housed in four production houses Hen-day egg production ( % ) , hatchability ( % ) and mortality in breeder flocks were measured from sexual maturity to 61 weeks of age and the complete record divided into three partial records as follow ; first partial record from the sexual maturity to 35 weeks of age , the second record(36 – 48 weeks of age) and the third record (49 – 61 weeks of age ) . The correlation coefficients were estimated among records and among production traits . The results indicated that there were highly significant effects of genotypes , records and the genotype × record interactions on all traits except the effect of records on mortality . The Hen-day egg production of Lohmann ( 57.24 %) was significantly lower than Fawbro and Hubbard which were 60.35 % and 59.82 % for the two hybrids, respectively . However, the hatchability of Fawbro eggs ( 86.15 % ) was highly significant than the other hybrids which were 82.79 % and 80.79 % , for Lohmann and Hubbard, respectively . Correlation coefficients between age and each of egg production and hatchability were negative and highly significant in Fawbro and Hubbard flocks, while the correlation coefficients between egg production and hatchability were positive and highly significant in all hybrid flocks . Correlation coefficients between the first partial record and complete record was positive and significant for egg production indicating the possibility of using first partial record for early evaluation for this trait in these hybrids .

This experiment was conducted to determine the compatibility of using the fungicide Thiabendazole with the biocontrol agent Trichoderma to control Fusarium solanl and Macrophomlna phuseolina causing- seed and root rot on soybean. Results showed that the two fungi, isolated from root and soil frequently cultivated by soybean, had the capacity to cause seed rot, seedling death, wilting, and root rot on soybean. The percentage of seed germination in' treatments of F. solani, M phaseolina, and the interaction between them were found to be, 36.6, 46.6, and 50 % respectively compared to 83.33% for the control treatment. It has been found that Thiabendazole showed II significant effect on the rate of the radial growth of the two fungi and on the dry weight of their biomass on cultural medium. The percentages of inhibition for F. solani was 27.6, 41.5,55.5,87.1, 100 % at concentrations 0.1, 0.2,0.4, 0.8, 1.6 mg/L of Thiabendazole respectively, 24.9, 40.0, 54.8, 85.5, 99.6 % for M. phaseolina at the above concentrations. The dry weights of the biomass for F. solani were 0.13, 0.04, 0.03, 0.04, 0.00 g for the above concentrations of Thiabendazole compared to 0.17 g for the control, 0.14, 0.11, 0.07, 0.03, 0.00 g respectively for M. phaseolina compared to 0.23 g for the control. No toxic effect of Thiabendazole on Trichoderma was observed. Thiabendazole was found to be effictive in suppressing the growth of both pathogens and increased the percentage of seed germination and decreased the desease severity on foliage and root system. The combination of Thiabendaznle with Trichoderma was found to be active to increase percentage of seed germination and decrease the disease severity on both of foliage and root system of soybeans.

Water samples were collected monthly from four sites on Army Canal in Baghdad, for the period from January 2009 to June 2009. All samples were submitted for chemical and biological tests. Hydrogen activity (pH) range was 7.3-7.4, Electrical Conductivity (Ec) range was 0.94-1.01 ds.m'", with significant difference in relation to sites. Range of calcium ions concentration was 3.1-3.6 mmoll-1, magnesium ions 3.1-3.2 moll-1, sodium ions 2.8-3.3 mmoll-1, potassium ions 0.1 mmoll-1, chloride ions 2.4-3.2 mmoll-1, sulfate ions 3.3-3.8 mmoll'", and carbonate. ions 3.3-3.7 mmoll-1 Total dissolved salts (TDS) ranged from 602-646 mg.l-1. There was asignificant difference in regard to sites only. Sodium adsorption rate (SAR) ranged from 1.55-1.80 along all the canals sites and through the six months of the study. Three classification systems were used to evaluate water suitability for agricultural purposes, United State Department of Agriculture (USDA) Classification System (1954), and the result was class (C3-S1) for all sites and months. FAO Classification System (1985), the result was "water with mild-moderate problems" for salt concentration represented by Ec, But for SAR and effect of Na concentration on soil permeability, the results were "no problem to use water for irrigation". FAO Classiftcation System (1992), its result was "low salt irrigation water", no sample was classified as "danger possibilities" in regard to SAR and its effect on soil permeability. According to an Iraqi Classification System, these samples were classified as "good quality water for agricultural and irrigation purposes". Biological tests revealed aerobic Ecoli, Salmonelta ,Shigilla and Feacal coliform according to WHO Guide for biological water evaluation (1998) .

To study the effect of different organic wastes and method of application to reduce effects of Salty Water on certain chemical properties of Soil Irrigated by Salty Water and the availability of N,P ,K. A field experiment was conducted in a clay loam Soil in the spring season / 2007 with a randomized complete block design in a factorial experiment to study two main factors: 1- sources of wastes: control (AO), sheep wastes (A), wastes of poultry (B) and wheat hay (C). 2- method of application: direct application to Soil (S), indirect, application by passing Drainage Water through organic wastes (W). The plots were Irrigated with Drainage Water (EC = 4.15 dS.m-1) by surface Irrlgation. Soil samples were taken at the end of experiment at depth of 0-30 cm to determine EC , pH, SAR and available N,P and K. The results showed that organic wastes reduced the EC and pH. However, sheep wastes had the best in reducing EC with a percentage of 7.80% , "and the indirect addition of wastes (W) was significantly superior in reducing EC with a percentage of 6.26%. While the CS treatment was' significantly superior in redueing the e.H of percentage 5.30/0. Poultry wastes were superior in the available nitrogen and phosphorus (258.3 , 19.4 mg. kg-1 Soil respectively), while the direct addition increase available potassium (142.16 mg.kg' Soil) and the indirect addition (W) gave the best available nitrogen (244.8 mg.kg-1Soll), From these results we conclude that addition of different sources of organic wastes reduced the EC , pH and SAR and increased available N,P,K. The indirect addition of wastes is better than the indirect addition, so recommend to use organic wastes at the indirect addition to reduce the effects of Salty Water which is use for Irrigation.
