EFFECT OF USING BIO – AND ORGANIC FERTILIZERS ON PRODUCTIVITY AND QUALITY OF CUCUMBER CROP UNDER PLASTIC HOUSES
2015
Al-Hmoudi, A. S. | Mohamed H. | Al-Menaway M. | Hussain A.
An experiment was carried out to study the effect of Bio and organic fertilizer on cucumber growth and yield during two successive seasons of 2010 and 2011 at Northern region in united Arab Emirates. The Queen cucumber hybrid was fertilized with different organic fertilizers i.e. Horse manure, compost, chickens manure and cows manure. Also using the bio fertilizer i.e. phosphobactein, Azotobacter and mycorrhizal. The results showed that cucumber yields differed in their response to the bio and organic fertilizer. The results showed that the compost was higher nitrogen percent and lower in C/N ratio, and pH, than the others organic fertilizer especially horse manure. The study demonstrated that the average cumulative cucumber yield was higher with compost + 22 (gm) mycorhizol/ plots treatments compared to other treatments throughout the experiment during the two successive winter seasons of 2010 and 2011. The plant height and plant fresh weight (g), with N100% mineral (control) deceased by 28% and 40% compared to N 100% organic (Compost) respectively during the winter season of 2010. The nitrogen, phosphorus and potassium content of cucumber fruits (%) significantly increased, as did the soil with the increase of organic fertilizes applied. The experimental results confirmed the combination of bio-and organic fertlizers could increase plant growth, yield and quality. It also confirmed that composted organic fertlizers can be used a source of nutration instead of chemical fertlizers for cucumber plants.

2015
Hany A.M. Srour
Salt stresses collectively are responsible for many crop losses worldwide especially salt -sensitive plants. The present study investigates the roles of exogenous application of glycinebetaine (GB, 5mM) in improving salt stress tolerance in salt sensitive green bean seedlings. Salt stresses (45mM NaCl for one week) significantly reduced leaf relative water (RWC) and chlorophyll (chl) content and increased percentage of electrolyte leakage, endogenous Proline and lipid peroxidation. Activities of peroxidase(PX), ascorbate peroxidae (APX), superoxide dismutase (SOD), and catalase (CAT), were significantly increased in shoots and roots of green bean seedlings subjected to salt stress. Exogenous application of GB improves salt tolerance of green been seedlings as shown by increased RWC and chlorophyll contents in leaves and reduced percentage of electrolyte leakage, lipid peroxidation and proline content. Under salinity stress condition, GB application decreased the activities of PX, CAT, APX and SOD in seedling shoots, whereas, it increased the activities of CAT and AP in roots. The result suggests that exogenous application of GB increased green bean seedlings' tolerance to salt-induced oxidative damage by upregulating their antioxidant defense system where this compatible solute protect plant cell against salinity stress.

Al-Akwa Ali | Mabrok Sharaf
In spite of the development observed in the area and production of potatoes crop in Yemen for the period of (1990-2010) to the level of self-sufficiency, the exported quantity, however, still very limited, It even decreased sharply in 2010 by 84.5%, compared to it's level exported in 2006. Stagnant productivity of potatoes in Yemen at around 13 ton only per-hectare, in front of (35- 45) ton/h globally, is believed to be the main obstacle standing behind the failure of exportation the Yemeni potatoes to the abroad. According to field study, several results have been obtained, the most important of which: The variables, such as, chemical fertilizer, equipment, manure and seeds are found to be the most effective factors on the output of potatoes. It is proved statistically significant at (0.01) level and responsible for the change occurred in the production of sampled individuals by 77% (R2), however, the result show that the quantity used in the production process of potatoes by mentioned above factors fill short to meat the level of optimal quantity required to maximize the profit. The size of optimal level of production was estimated at (19.9) ton and the price of potatoes accepted by producers was estimated at 121390 YR/Ton. According to percentage of importance, seeds came first at the total variable cost by 31%, then, irrigation by 17.6%, fertilizers and pesticides 14.6%. Net revenue was estimated at (493640) YR, and the benefit /cost ratio was estimated at 1.40. The most important recommendation reached by this study is directed toward more using inputs in process of production by producers of potatoes, to maximize profit and increase productivity of area cultivated.

Dalia G.I. Gabr
Morphological structure and different characters of achene is most important from the taxonomic point of view. In present study achene shape, colour, size, texture and pappus type were recorded for 20 taxa of Asteraceae by using light microscope (LM) and scanning electron microscope (SEM). Examination of pappus by SEM recorded 6 groups; (1- Scarbous barbellate fine bristles and scarbous barbellate bristles, 2- Scarbous subulate scales free, 3- Scarious scales, 4- Paleaceous scales corona, 5- Plumose bristles and 6- Capillary barbellate). Also eight patterns were recognized based on surface sculpturing pattern: reticulate, with two subtypes, tuberculate, sulcate, puncticulate, colliculate, aculeate, lineate and striate. The data proved useful in the construction of a dichotomous indented key to the studied taxa. Twenty-two characters with 85 characters stats were used to generate anatomical key using the DELTA key-generating programs.

2015
Diab, A. M.
The purpose of this study was to 1) assess the linkages in the New Valley’s Agricultural Innovation System (NVAIS) and 2) characterize the information structure underlying the system. Data were collected from 50 respondents represent the nine components of the studied system during the period from Feb. to Mar. 2015 using in-depth interviews. The graph theoretical technique (GTT) was used to assess the linkages and information structures in the studied system. The obtained results showed that NVAIS was not fully identified; however, 44 of a total 72 linkages only were identified, and have a density of 0.61. Only 14 linkages are established through specific linkage mechanisms so density declines to 0.19. The component "Observatory of Development and cooperatives (O)" is by far the main sender of information, followed by the component "Extension (E)" and "Higher Education (H)". The main receivers of information, is the component of "Farmers (F)". Components of "Research (R)" and "Policy (P)" have a special position in this system, being the most interactive components as it sends as much information as it receives from others. Components of Secondary agricultural schools (S) and Agricultural Credit (C) are candidates to reform because of they interacts other components at a low tone. The component of private input supply, marketing and processing (M) is isolated is needs to deal efforts on enhancing its interaction within other components of the system. Any interventions on the components of O or F will be reflected in all over the system because the first one is a dominant component while the second is subordinate. The intermediary institutions, O and E, should play a more active role in bringing together other components. Specifically, links between these components could be strengthened through policy dialogues where the O and E could pass information from S, F, M, and C to P, H and R; such transmission of information should help P, R and H reassess agricultural policy, research and education priorities

Hanady M. Abdel-Radi | Rehab S. Ibrahim | Abeer A. Kinawy
The main objectives of the research were to identify the size of wheat gap and find the appropriate solutions to apply wheat self-sufficiency in the near future through designing micro economic equilibrium model for wheat during the period (1995-2013) the model may identify the change in government revenues, the change in foreign exchange earnings and the rate of tariff, the coefficient of the tariff and the change in surplus producers, the change in the surplus of consumers, efficiency indicators of a return or social loss in production and yield, and social loss in consumption and total return. The study predicted increasing in government loss about LE 13.287 billion in 2014 to about LE 20.11 billion, increasing in foreign exchange earnings of about LE 11.64 billion in 2014 to about 18.07 billion pounds, and it also expected to increase in the implicit tax (of the tariff rate) by the domestic producer of about 0.17 in 2014 to about 0.25. The study also predicted continuing socio loss in production to reach about LE 1.92 billion in 2020 because of continued rising in production costs, which is expected to reach about LE 5707 per acre in 2020 with increase ratio about 18.32% compared to 2013. It was also expected to continue growing consumer surplus to reach around LE 10.7 billion in 2020 and because of the government's continued support in the bread system.
Mostrar más [+] Menos [-]AN ECONOMIC STUDY ON THE PRODUCTION AND CONSUMPTION OF DAIRY IN EGYPT
2015
Adam, H.H. A. | Walaa M. Mohammed
Dairy is considered one of the most completed and balanced healthy food needed by human as it contains many important elements and vitamins as well as it protects the body from many diseases. This research aims to identify the current situation of the dairy production and consumption in Egypt in order to know how far is the gap between them. In addition , it studies all factors that affects the production and consumption processes in order to set some recommendations that help in reducing this gap in Egypt. The research refers to the value of dairy production in Egypt that reached about 2.425 billion pounds in 2013, which represent about 8.53% of the agricultural production and 5.24%of the animal production. The annual growth rate for this value during the study period (1995–2013) was about 4.23%.Buffaloes and cows contribute more than 97% of the total dairy production in Egypt, while the goats contribute the remaining. The total dairy production in Egypt reached about 5.554 thousand tons in 2013. This production takes a growing trend with a statistically significance rate of 119.10 thousand tons which represents 4.01%of the annual average of the total dairy production during the period of the research. The research also indicates that there are many factors affecting the quantity produced from dairy in Egypt; the most important of which were the quantity produced from clover, the produced quantity from dry feed, the wholesale price of milk, and the value of loans granted for livestock. The results of the research indicate that there is a proportional effect and statistically significant between each of the quantity produced from clover, the wholesale price of milk ,and the value of loans granted for livestock upon the quantity produced from dairy in Egypt during (1995-2013). The total national consumption of dairy in Egypt was about 6.516 thousand tons in 2013. This consumption takes a growing trend with a statistically significance rate of 156.24 thousands tons which represent 2.68% of the annual average of the quantities consumed during the period of the research. Due to the inability of the local production of dairy in confronting the amount of consumption , a gap between the production and consumption milk has emerged in Egypt estimated at about 962 thousands tons in 2013, which indicates that the self-sufficiency rate did not even exceeded 85.24 % in that year. The research also refers to the factors that affected the quantities consumed of dairy in Egypt which represented in the population, average per capita dairy, average personal income, the average retail price of milk, and the average retail price of eggs . By using the multiple demand function of dairy in Egypt, it was found out that there is a directly relationship and statistically significant between the required quantity and income, while there is an inverse relationship and statistically significant between the required quantity and the retail price of milk. But it did not demonstrate a statistically significant relationship between the required quantity and each of population and the retail price of eggs. The research recommended the following 1- The need for attention to cultivate clover and dry feed as it is one of the most important factor responsible for increasing the dairy production in Egypt. 2- There must be an interest in raising Buffaloes and cows to increase its production as they contribute over 97% from the total dairy production in Egypt. 3- Reducing the marketing costs of dairy as much as possible to raise the marketing efficiency 4- Reducing the interest rates on cash loans that specified for developing livestock in the field of dairy production. 5- Providing veterinary care at suitable prices
Mostrar más [+] Menos [-]EFFECTS OF PLANT GROWTH PROMOTING RHIZOBACTERIA ON SUMMER SQUASH GROWTH, YIELD, NUTRIENTS UPTAKE AND AVAILABILITY UNDER NITROGEN AND PHOSPHORUS FERTILIZATION LEVELS
2015
Elwan, M.W. M. | Abd El-Azeem M.
Two field experiments were conducted at the Experimental Research Farm, Faculty of Agriculture, Suez Canal University, Egypt during spring 2013 and 2014 using summer squash (Cucurbita pepo cv. Eskandarani) for studying the effects of PGPR strains. The objective of the first experiment was to study the efficiency of single, double and triple inoculations of Azospirillum brasilense (AC1), Bacillus subtilis (AC2) and Serratia marcescens (BM1) on summer squash fruit characters. Results showed that the double inoculations of tested PGPR strains in addition to single inoculation with Serratia marcescens produced non-significant higher fruit yield and average fruit weight compared to triple inoculation (AC1+AC2+BM1) and single inoculation with Azospirillum brasilense. However, non-inoculated control plants and plants inoculated with Bacillus subtilis showed lower fruit yield and average fruit weight. From the previous results, it concluded that the double inoculation were better than single and triple inoculations. However, the aim of the second experiment was to evaluate the efficiency of PGPR under N and P fertilization levels on plant growth, yield and nutrients uptake of summer squash as well as soil nutrient availability (available N and P). As per main effects, generally, plant growth, fruit yield, nutrients uptake and availability enhanced significantly by increasing N and P levels, except half dose of P which gave statistically equivalent values of plant fresh and dry weight as well as nitrogen uptake in shoots and fruits in addition to P in shoots compared to full dose. Also, main effect of PGPR showed that the inoculated plants gave significantly higher plant growth, fruit yield, nutrient uptake and availability compared to un-inoculated control plants. Inoculated plants with PGPR strains under full dose of N and P gave mostly highest plant growth, fruit yield, nutrients uptake and availability. This effect was at significant level in terms of fruit yield, soil nutrient availability and some nutrients uptake such as K in the shoots and N the fruits. Furthermore, PGPR significantly reduced P fertilizer application without any reduction in squash yield, especially under no and half dose of N fertilizer. Results revealed that the efficiency of PGPR strains increased by P increasing and decreased by N increasing.
