The aims of this study were to know the accumulated effects of alcoholic leaves extracts of henna and huds plant in some biological aspects of immature stage Musca domestica .four concentrations have been used, 500, 750, 1000 and 1250 mg L-1 for both two plant extracts and four replications for each concentration, their effect on life cycle ,growth stadium of immature stages (eggs, Larvae, and pupae), pupae weight .There was no significant effect for both extracts in egg incubation period, where it was 1.50 and 1.75 days at a concentration 1250 mg L-1. There was an increasing in duration of 1st,2nd ,and 3rd larvae phase ,whereas it reached 1.50, 2.75, and 5.75 days, and 1.75, 2.75 and 6.25 days respectively for huds and henna at a concentration 1250 ppm, when it compared with control which were 1, 2, 4.25 days for 1st, 2nd, 3rd larval respectively. The mortality increased with increasing of concentration, where the maximum egg mortality % was 20% and 22.50% in huds and henna extracts ,and in first larval phase (most effected) the mortality came to 26.26 % and 27.82% for both huds and henna extracts at aconcentration 1250 ppm respectively, and a reduction in pupae weight that reach 0.038gm and 0.036gm in huds and henna respectively, wheas it was 0.092 gm in control.

A field experiment was conducted at the experimental farm, College of Agriculture, Al-jadrea, Baghdad, Iraq during spring season of 2016 to study the effects of foliar application with yeast extract on grain yield, yield components of five sorghum cultivars. The layout of the experiments was split plot design with three replicates , The five cultivars it is kafeer, bohooth 70, rabih, inkath and local, occupied the main plots while yeast extract concentrations 0, 5, 10,15 gr L-1 occupied the sub-plots. Results of this experiment are summarized as follows: number of seeds per head, seed yield increased with the increase of yeast extract concentrations and the best concentration in most of yield characters was 15gm L-1. The cultivar buhooth 70 was superior in 1000 seed weight, seed yield while the cultivar Rabih was superior in number of seeds per head.

Pot experiment was conducted at the Faculty of Agriculture / Anbar University during the Fall 2014 season as the study included two factors: the first is the irrigation water and three types: water and river water with salinity 4 dS m-1. In addition, with salinity 6 dS m-1, and the second factor is the organic extracts (Peat reeds) and three levels: 10, 20 g L-1 and it was sprayed three times. The study was conducted using three replications and randomized complete design sectors (RCBD). 2014 to study the effect of salt water and peat reeds use in some recipes the soil and the growth of corn, the results showed the following: -
Plant high and dry weight were decreased when irrigation done with salty water 4.0, 6.0 dS m-1 since they were 33.11 cm and 9.80 g pot-1, respectively, comparing with river water 0.92 dS m-1, which showed 33.94 cm and 10.27 g pot -1 respectively. Increasing organic extracts led to increase in dry weight, since it was 8.74 g in no- spray and increased to 11.21 g in spray level 20 g L-1., plant height increase with in organic extract spray level from 32.72 cm to 34.55 cm. Increasing salinity of irrigation water has led to a decrease in the concentration of each of the elements nitrogen and phosphorus in soil, reaching 63.74 and 1.31 mg. kg-1, respectively, comparing with control 103.71 and 2.14 mg kg-1. Potassium was non- significantly, increase was 32.37 mg kg-1 in the level of 6.0 dS m-1., comparing with irrigation with sweet water 0.92 dS m-1. Which was 24.57 mg kg-1 in the soil after planting Decrease in concentration of nitrogen, phosphorus and potassium in the dry weight of corn in the level of 6.0 dS m-1. It amounted to 10.56 and 1.97 and 32.3 mg.kg-1, respectively, an increase of salinity levels in irrigation water comparing with sweet water 11.12 and 2.76 and 4 0.07 mg kg-1 respectively.
Increase concentration of nitrogen, phosphorus and potassium when sprayed organic extracts (Peat reeds) in the dry weight of the plant maize the highest concentration 12.10, 2.90 and 38.8 mg kg-1, respectively, were obtained from comparing with control 9.45, 1.95 and 32.5 mg kg-1 respectively. Concentration of nitrogen of potassium, phosphorus, Increase in the soil after planting organic levels of organic extracts (Peat reeds) of the level 20 g. L-1, they were 96.39, 1.85 and 33.93 mg kg-1, respectively, comparing with control 69.53, 1.53 and 19.89 mg kg-1 respectively. Values of soil pH were decreased with increases of organic extract levels and irrigation water salinity they decreased from 7.65 to 7.56 and from 7.65 to 7.51 respectively. Values of electrical conductivity in the soil was increase with salinity of irrigation water it become 1.62 dS.m-1. In the level of (6.0 dS m-1). After it was 1.24 dS.m-1. In the irrigation with sweet, water 0.92 dS m-1. Value of electrical conductivity was increase when using organic extract, it decreased from decreased from 1.47 dS m-1. Spray level of 10 g L-1 of the organic extract to 1.33 dS m-1, at the level 20 g L-1.

Abstract
The research was conducted by using the ethanolic extract and powder of Eucalyptus leeves to evaluate their effect on some biological aspects of potato tuber moth in the laboratory . Results showed the important role of Eucalyptus extracts on potato tuber moth , the ethanolic extract of Eucalypt leeves prolonged the period of egg development which increased to 7.33 days by using 10000 ppm while the egg hatching percentage was decreased to 71 % at the same dose of extract , Adult emergence was decreased to74.67% and females fecundity decreased to 57.33 egg. Pupae treated with 10 % powder resulted in prolonged development period which reached to 15.33 days . Potato tubers treted with extract decreased number of egg on tubers by females to10.33 egg at 10000 ppm . There was also a clear effect for the ethanolic extract in larvae growth , percentage of number of first instar larva decreased by 91.3 % , and third instar larva decreased by 61 % when using 10000 ppm of ethanolic extract . These results indicated the possibility of using the natural materials of plants which are safe, cheep and active for pest control .

This study was conducted in the cold storage unite in the Dept. of Hort., College of Agric., University of Baghdad starting in 20/ 1/ 2009. The white strain of oyster mushroom was imported from Jordan. The spawn was grown on wheat seeds. Wheat straw was used as substrate. Commercial formaldehyde 2% was used for sterilization of the straw. Plastic bags (30 X 51 cm) was used and 1 kg of moist substrate in each bag used for spawning. The bags were transfered to the incubation room at 25 ± 2ْ c for one month then to the growth room. Humidifier was used to raise the humidity to 80-90% and fluorescence lamps were used to raise light to 400 Lux. Water extract of liquorice roots (Glycyrrhiza glabra) was used with the following concentration: 0% , 5% , 10% , 15% and 20%. The extract was injected (30ml.) inside the plastic bags using 50 ml. syringe. Injection was done during three stages of growth. The first injection was in the middle of the incubation stage and the second injection was in the begning of the Pinhead stage and the third injection was in the begning of the fruiting body stage. The results showed that treatments with Liquorice root extract during the three stages significantly increased fruiting body weight and total yield and dry yield and the biological efficiency of oyster mushroom. Treatments also reduced the production cycle and increased the percentage of dry matter, and increased the percentage of protein content of the fruiting body. Storage life of the oyster mushroom was improved because of the reduction of weight loss and dry matter loss and protein loss during 15 days of storage at 2 ±1ْ c. Treatments with liquoric extract in the begging of the fruiting body stage reduced the percentage of decay during cold storage. The results of this study showed that the best growing stage for liquorice extract treatment was the beging of fruiting body stage and the best concentration was 20%. Treating oyster mushroom with 20% Liquorice extract in the begging of the fruiting body stage increased fruiting body weight to 15.98 g and increased total yield to 852.8 g/kg of substrate and increased the dry yield to 115.42 g/kg of substrate and increased the biological efficiency to 85.3%.
