A two – year field trial was conducted in El-Boustan region, South El-Tahrir Province, El-Behira Governorate, Egypt to decrease mineral nitrogen (N) inputs of sunflower and increase yield and quality of the intercrops to achieve farmer's benefit under sandy soil conditions. A split-plot design with three replicates was used. Quality of sunflower and soybean seeds was tested in the laboratories of Seed Technology Research Department, Field Crops Research Institute, Agricultural Research Center. For soybean crop, average yield of soybean with sunflower was greater by intercropping soybean with sunflower that spaced at 40 cm in the same ridge. Slow – release N fertilizer rates of sunflower did not affect all the studied soybean traits. Also, soybean yield and its attributes were not affected by the interaction between sunflower plant spacing and slow – release N fertilizer rates of sunflower. Seed oil content of soybean was increased by increasing sunflower plant spacing from 20 to 40 cm, meanwhile quality of soybean seeds was not affected by slow – release N fertilizer rates of sunflower or the interaction between sunflower plant spacing and slow – release N fertilizer rates of sunflower. For sunflower crop, intercropping soybean with sunflower that spaced at 20 cm had the highest seed and oil yields per ha compared to the others. All the studied sunflower traits were increased by increasing N fertilizer rates of sunflower from 71.4 to 142.8 kg N/ha except number of leaves per plant. The interaction between sunflower plant spacing and slow – release N fertilizer rates of sunflower affected significantly all the studied sunflower traits except number of leaves per plant. Quality of sunflower seeds was not affected significantly by sunflower plant spacing but it was increased by increasing N fertilizer rates of sunflower from 71.4 to 142.8 kg N/ha. The interaction between sunflower plant spacing and slow – release N fertilizer rates of sunflower did not affect quality of sunflower seeds. Land equivalent ratio values for intercrops were much greater than 1.00 indicating less land requirements of intercropping systems than sole sunflower. Farmer's benefit was achieved by intercropping soybean with sunflower plants that spaced at 20 cm between hills (50% soybean + 100% sunflower) and received 75% of the recommended mineral N fertilizer rate of sunflower under sandy soil conditions.

Abstract Aim There have been little published data about extrapulmonary tuberculosis (EPTB) situation in Egypt. The aim was to throw some light over EPTB patterns in Egypt regarding demographics, sites of affection, and treatment outcome. Methods This work was a retrospective, descriptive analysis of EPTB cases, carried out at El-Behira Chest Hospital and 14 related dispensaries. All available data about registered EPTB cases from January 1996 to December 2010 (15 years duration) were collected including demographic data, site of EPTB, previous treatment history, treatment category, and treatment outcome. A descriptive analysis of the data was performed using the SPSS statistical program. Data were described in absolute numbers and percentages. Statistical significance was set at P value less than 0.05. Results EPTB [n = 2119 (21%) of all diagnosed tuberculosis] occurred more in age groups between 15 and 29 and 30 and 44 years [n = 965 (45.5%) and n = 572 (27%), respectively] and in male patients [n = 1233 (58%)] than in female patients [n = 886 (42%)]. Pleural [n = 1341 (63.3%)], bone [n = 157 (7.5%)], and renal [n = 34 (1.6%)] tuberculosis were more common in male patients [n = 856 (64%), n = 99 (63%), n = 22 (64.5%), respectively], whereas lymph node [n = 427 (20%)] and genital [n = 70 (3.3%)] tuberculosis were more common in female patients [n = 240 (56.5%), n = 42 (60%), respectively]. Regarding treatment outcomes, successful treatment was obtained in 1725 cases (81.5%), treatment failure in 13 cases (0.5%), defaulting in 179 cases (8.5%), death in 77 cases (3.5%), and transfer-out in 125 cases (6%). Number of cases diagnosed declined through the years of study and was the highest in winter months, peaking in March. Conclusion EPTB is a burden of reproductive age groups (15–44 years), with pleura being the commonest site of the disease that occurred more in male patients and age groups 15–44 years, followed by lymph nodes that occurred more in female patients and age group below 15 years. Successful treatment outcome was obtained in 81.5% of EPTB cases.

IMPACT OF BUBBLER DISCHARGE AND IRRIGATION WATER QUANTITY ON HYDRAULIC PERFORMANCE EVALUATION AND MAIZE BIOMASS YIELD

The aim of current research work is studying the effect of two bubbler irrigation discharges (BD) were: a) 8 LPH and b) 12 LPH, and different water quantity treatments from evapotranspiration (ET): 100%, 75%, 50% on uniformity coefficient (UC%), emission uniformity (EU%) and coefficient of variation (CV%), maize (Zea mays-L., HF-10 Varity) grain and Hay yield. The experiment design is split in randomized complete block with three replicates. So, field experiment for one growing season (2014) was conducted in sandy soil at the Agricultural Research and Production Station of National Research Centre, El- Nubaria, Elbehira Governorate, Egypt. Irrigation water was added in order to compensate for ET of maize. Obtained data could be summarized as follow: Parameters under study could be ranked in following descending orders: 8 LPH>12 LPH and 100>75>50 for bubbler discharge treatments, except for CV%. Investigated bubbler discharge (8 and 12 LPH), increase operating pressure head, getting improvement in UC%, EU% and decreasing CV values. With respect to BD and ET% effect on UC, EU%, maize hay yield, and significant difference at the 1 % level between all mean values of bubblers and ET% treatments were obtained. The interaction effects of the investigated factors, the highest and lowest values of maize hay yield were recorded under 8 LPH X 100% and 12 LPH X 50% ET treatments. These attained results were attributed to the improvement in hydraulic parameters of UC%, EU% and CV Also the Irrigation treatments of 100 and 75% from ET were covered water requirements and also recorded convergent results in values which means that the quantity of water added (which is the difference between the 100-75% =25% ET). It's amount, in excess of the plant required under the current conditions of the experiment. So it can be recommended to using 75% for saving 25% from water requirements under bubbler irrigation system using 8 LPH bubbler.

THE PRESENT investigation was carried out in a private farm …..located at Alexandria desert road, El-Behira Governorate, Egypt to study the effect of bagging type on reducing pomegranate fruit disorders and improving fruit quality during 2011 and 2012 seasons. The bagging treatments were, brown paper bag, white paper bag, prgmen bag, agrail white bag, agrail red bag, agrail blue bag and plastic bag. The treatments started at 21 days after fruit set and sustained till harvest time. The obtained results showed that, bagging fruits with prgmen bag increased fruit length, fruit diameter, grain weight percentage, fruit weight (g), yield/tree (kg), TSS %, total soluble sugars, vitamin C content and total anthocyanin content in fruit juice. While, the percentage of cracked fruits, sunburn fruits /tree and fruit mechanical damage were reduced as compared to the other treatments. On the other hand, bagged fruits with plastic bags increased peel weight percentage and total acidity percentage. Moreover, bagging with agrail blue bag had a significant effect on increasing values of lightness (L) .While, bagging with prgmen bag had a significant effect on higher values of lightness (L) and redness (a) compared to the other treatments. Generally, it can be recommended from this study that, bagging pomegranate fruits with prgmen bags was the best in reducing fruit disorders with improving fruit quality as well as increasing the net profit for farmer.

Adverse biochemical effects of various pesticides on sprayers of cotton fields in El-Behira Governorate, Egypt

A total of 60 healthy pesticide sprayers (smokers and non-smokers) in cotton fields exposed to different classes of pesticides for many years were compared with controls matched for age with respect to serum cholinesterase (ChE), serum total protein, alkaline and acid phosphatases (ALP and AP), lactate dehydrogenase (LDH), gamma-glutamyl transferase (GGT), creatine kinase (CK), blood glucose, serum hormones FSH, testosterone and L-thyroxine (T4). Significant increase was observed in serum ALP, AP, LDH, GGT, CK, serum hormones FSH, testosterone, L-thyroxine and blood glucose. Significant decrease in serum total protein and ChE. The increase or decrease in the tested biomarkers was more pronounced in the smokers than non-smoker workers. These results suggest that the long-term exposure of various pesticides on sprayers of cotton fields affect the normal functioning of different organ systems and may produce characteristic clinical effects.

MAXIMIZING POTATO PRODUCTION VIA NITROGEN FERTILIZATION AND PLANT SPACING

The potato plants (Solanum tuberosum L.) vs. valor were exposed to different levels of nitrogen fertilizer (60, 100, 140, 180 kg N/feddan (4200 m2)) and in-row plant spacing (12.5, 25 and 50 cm) for maximizing the yield production to match food security needs under climate change impacts on Delta region, Egypt. The experiment was carried out during two growing seasons (2010/2011 and 2011/2012) in split plot design at El-Bossily Farm, Agricultural Research Center, El-Behira Governorate, Egypt. The vegetative growth characteristics and yield parameters were measured. The result of this study verified that increasing nitrogen level up to 180 kg N/feddan significantly increased the vegetative growth, total and marketable yields than the other N treatments. The in-row plant spacing 50 cm was significantly increased vegetative growth and yield (kg/plant), but the total yield (kg/m2) had different trend. The highest total yield /m2 was obtained by 12.5 cm treatment. The interaction effect of 180 kg/feddan of N and 12.5cm in-row plant spacing were increased the total tuber yield (kg/m2) significantly. In contrary, the best marketable yield (tubers > 35 mm) /m2 was obtained by 25 and 50 cm in-row plants. This study was concluded that the best agronomic practices for potato production obtained by application 180 kg N/feddan of with in-row plant spacing 25 cm treatment. The economical consideration of the different treatments showed that the best total net income was obtained by 180 kg/feddan N with 50 cm in-row plant spacing.

ENVIRONMENTAL IMPACT TO UTILIZING SOME FOOD INDUSTRIES WASTE AS A LIQUID ORGANIC FERTILIZER AND THEIR EFFECTS ON PLANTS UNDER SALINE CALCAREOUS SOIL

The objective of this work is toassess the suitability of utilizing food industries waste (molasses and orange waste) to produce natural liquid organic fertilizer and evaluation their effects on plant and soil.A preliminary experiment was conducted at the greenhouse of Agricultureal Research Centre (ARC) at Giza Governorate, Egypt to test the effect of molasses or orange waste extract on the growth of maize ( zea maize) during the summer seasons of 2011 followed with barley (Hordeum vulgare) during the winter seasons of 2011/2012. The field experiment was carried out to verifying the effect of molasses or orange waste extract on maize plants. Maize grains were planted in the experimental farm of Nubareia Research Station (El-Behira Governorate), Egypt. Grains of maize were sown in summer growing season of 2012. The obtained results showed that applying both aqueous extracts to soil increases the amount of soil organic matter and decreases the ECe of the soil. Avery slightly differences were observed in pH and CaCO3% of soil. There is positive effect of both P1 and P2 (molasses or orange waste) on the growth of field crops. The application of these extracts significantly, increased grain and straw yield as well as improved nutritional values of grain, i-e., total carbohydrates, crude protein, oil, total amino acids, organic acids, and hormones. The efficiencies of either extracts as a fertilizer or as amendments compared to control treatment are very different. There was excellent potential to obtain a natural fertilizer and an amendment using molasses. On the other hand, the best results of orange waste extract were obtained as an amendment rather than a fertilizer.
