Effect of planting technique and water stress on vegetative growth of Zea mays L.

Abstract
A field experiment was carried out at the experiment field of department of field crops sciences . Baghdad variety during 2017 spring season is new Baghdad plant nursery in Diyala directorate of agriculture in Diyala province . According to the split plots design with three replications . The water quantity( 8400m3/h) was occupied the main plots while agriculture technique methods (plastic , cork , prose and conventional) was occupied the sub plots seedling were transferred to the permanent field in 15/3/2017 . Seedling were transferred to the permanent field in 15/3/2017 when seedling were to 5 leaves after 30 days from planting and seed planting of conventional agriculture method in the permanent field in same date of seedling agriculture. Results have shown that water quantity (8400m3/h) gave best average results in single leaf area , leaf area index and the conventional agriculture gave the highest average in number terrestrial papers. There was a significant overlap between the treatment of water stress and the methods of agriculture in all the character under study . The synthesis of water quantity (8400m3/h) to agriculture with plastic dishes was given highest average in the number of total leaves and number of green leaves and single leaf area and leaf area index . While the synthesis of quantity water (8400m3/h ) for conventional agriculture was given the highest average in number terrestrial leaves .
Keywords: Breeding technique, water stress, yellow maize, vegetative characteristics

Effect of the type of cassis in some of the natural characteristics of the fruits of the dates palm and orchid palm varieties

Abstract
This Study was carried out in Khales- Diyala province in national orchard. During growth season 2016 on two cultivars (Khestawi and zahdi), the aim was to investigate the effect of bunches bagging practice with used six types of bags ( control, clear polyethylene, green perforated polyethylene, perforated cloth, brown cheese cloth, white cheese cloth) to reducing the effect of high temperature degree, reducing wrinkle and dropping fruits and increase fruit water content.
The result of study showed that: the bunches bagging treatments significantly increased the bunch weight for both cultivars. The bagging with green perforated polyethylene gave the highest bunches weight for CV. Khestawi, and bagging with perforated cloth gave the highest bunch weight for C. V. Zahdi.
Fruit weight, flesh, length and seed weight was not significant at the bunches bagging in CV. Khestawi only. While in C.V. Zahdi the bunches bagging with brown cheese cloth was significantly increased the fruit weight rate and length, bagging with white cheese cloth gave a lower seed weight rate, while the baggig treatments didn’t effected of flesh weight rate.
Key words: bagging, high temperature, date palm, khestawi , zahdi .

Chromatographic and Spectrophotometric Analysis of Endosulfan in Vegetables

Abstract

A High Pressure Liquid Chromatography (HPLC) and Spectrocopic methodologies have been validated for the determination of α Endosulfan, β Endosulfan and Endosulfan Sulphate in tomato “Lycopersicon esculentum Mill”. The chromatographic separation method was based on Liquid-Liquid Extraction (LLE) using two immiscible solvents. Acetonitrile/water mixture (70/30, v/v %) was used as a mobile phase. The HPLC was equipped with UV/visible detector, the separation was achieved on μ-Bondapak C18 column with dimensions, 4.0 x 125 mm and 5-micron particle diameters using activated florisil to remove the interferences from the extract. The chromatographic experiments were carried out in triplicate at three fortifications levels 1, 2 and 3 Part per Million (ppm). HPLC’s detector was linear for the determination of pesticides with Correlation Cofficient (r) values < 0.99. The Limit of Detection (LOD) values was 0.020071, 0.002352 and 0.01619 ng/ml. The Limit of Quantification (LOQ) values were 0.066903, 0.0078414 and 0.05396 ng/ml. The Recoveries percentage (R) of the pesticides studied ranged from 88.13% to 98.77%, 84.60% to 96.86% and 82.90% to94.85% and the Coefficient of Variation (CV) values ranged from 0.003 to 0.005, 0.005 to 0.0057 and 0.004 to 0.007 for α Endosulfan, β Endosulfan and Endosulfan Sulphate, respectively. The spectrophotometric method was based on the liberation of sulphur dioxide after addition of alcoholic potassium hydroxide, the liberated sulpher dioxide was passed through hydrogen peroxide and diphenylamine and the light violet color of diphenyl benzidine was measured at 605 nm using spectrophotometer. The Spectrophotometric experiments were carried out in triplicate at three fortifications levels 3, 5 and 7 Part per Million (ppm). The spectrophotometer showed a linear response for the detection of pesticide with (r) value >0.99. The Limit of Detection (LOD) value was 0.089953ng/ml, the Limit of Quantification (LOQ) value was 0.299843ng/ml. The Recoveries percentage (R) values ranged from 89.23%to 99.02% and the Coefficient of Variation (CV) values ranged from 0.01407 to 0.02820. The levels of Endosulfan recovered in both methodologies were above the Maximum Residue Level (MRL) of Endosulfan in tomato (0.5 ppm).
Keywords: HPLC, Endosulfan, Chromatographic, Spectrophotometric, Pesticides.

Effect of irrigating iron on vegetative and syphilis growth of five cultivars (Vicia faba L.)

Abstract

experimental field experience during the agricultural season 2016 to study the estimation of genetic parameters for varieties of the faba bean Under the influence of irrigated iron spry and the study included two factors ; The first is irrigated iron (13% iron W / W) and Add on three levels of 0 g.l^-1 , 1 g.l^-1 , 2 g.l^-1 , and the second factor is five varieties of the faba bean and its Lortolano, Aquadulce, Luz de otono, Superaguadulce and the local class Hawija ,  And the study included 15 treatments , The results were statistically analyzed in split plot system within the design of complete random sector (R.C.B.D.(and three replicates and the results were compared using the Dunkin multidisciplinary test at a potential of 0.05 . The results showed that the cultivated plants at the level of irrigated iron were higher than 1 g.l^-1 in plant heigh and total number of flowers , and the plants planted at the level of sprying 2 g.l^-1 in the number of flowers in the cluster . The varieties differed significantly in most traits , Lortolano is superior to plant height , Luz de Otono is superior to the total number of flowers , While Hawijah gave the highest values in the number of major branches in the plant and the number of levels in the plant and the number of flowers in cluster .
Keywords: fermented iron, beans, varieties, qualities of growth .

Abstract
This Study was carried out in Khales- Diyala province in national orchard. During growth season 2016 on two cultivars (Khestawi and zahdi), the aim was to investigate the effect of bunches bagging practice with used six types of bags ( control, clear polyethylene, green perforated polyethylene, perforated cloth, brown cheese cloth, white cheese cloth) to reducing the effect of high temperature degree, reducing wrinkle and dropping fruits and increase fruit water content. Fruit chemical characteristic: the bunches bagging had no significantly effect on fruit water content in CV. Khestawi .The bunches bagging treatments had no Significant effect was recorded in C.V. Zahdi. No Significant effect was recorded in tannins in both cultivars. Fruit physiological characteristic: bunches bagging treatments didn’t effected on fruits maturity and fruits damaged in both cultivars, the bunches bagging of clear polyethylene had Significant decreased dropping fruits in CV. Khestawi, but no Significant effect was recorded about dropping fruits in C. Zahdi.
