Nahed, M.M. El-Shimi
Two field experiments were carried out during two early summer seasons of 2012 and 2013 years at the Experimental Farm of Kaha Station, Qalubia Governorate to study the response of snap bean plants Poulista c.v to some agricultural treatments for early green pods yield production using (flowering, amcotone, super phosphate solution compounds) as foliar nutrition, (charcoal, agriculture sulphur and charcoal + agriculture sulphur) as soil addition and( Pea, onion and broad bean) as protection plants, in addition using black polyethylene plastic as a soil mulch. The results indicated that spraying the plants with flowering and amcotone compounds followed by super phosphate solution had the highest values of fresh and dry plant weight. While addingcharcoal to the soil before sowing snap bean seeds gave the highest values of no. of leaves/ plant followed by spraying withflowering and amcotone compounds, respectively. The data showed also that spraying the plants with flowering, amcotone compounds, super phosphate solution, adding charcoal + sulphur and soil mulch with black polyethylene plastic exerted the highest values on all parameter of green pods its and yield attributes in both growing seasons. Concerning total sugars in dry pods it's clear that using protection plants with broad bean followed byonion were the best treatments on it. Generally it can recommend using any one of the mentioned treatments in this experiment especially flowering, amcotone compounds, super phosphate solution, charcoal + sulphur, respectively to obtain high green pod yield either early or total with the best quality.

Mostrar más [+] Menos [-]AN ECONOMIC STUDY ON THE PRODUCTION AND CONSUMPTION OF DAIRY IN EGYPT Texto completo
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

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.

Mostafa, R.A. A.
The beneficial effects of boron, zinc and active dry yeast on yield and fruit quality of Zaghloul date palm grown at the Experimental Orchard, Faculty of Agriculture, Assiut University, Egypt was studied during 2011, 2012 and 2013 seasons. The experiment was set up in a complete randomized block design with ten replicates each of one bunch. All treatments were sprayed two times after fruit set and one month later. The obtained results could be summarized as follow: - Boron, zinc and active dry yeast sprays significantly increased the fruit retention percentage and bunch weight compared to the untreated ones. Yeast application was more effective compared with boron or zinc application. - Spraying either yeast, boron or zinc at any studied concentration was accompanied with improving fruit quality in terms of significant increase in fruit weight, total soluble solids and sugar contents. No significant differences were detected between spraying with yeast at 250 or 500 ppm, 500 or 1000 ppm zinc, as well as, boron at 1000 or 2000 ppm. Moreover, active dry yeast spraying revealed the highest improvement in palm yield and fruit quality. However, it can be concluded that spraying either boric acid, zinc sulphate or active dry yeast twice after fruit set and one month later increased the palm yield and improved the fruit quality of Zaghloul date palm. Meanwhile, using dry yeast as more effective than both boric acid and zinc sulphate.

Pot trials were conducted under plastic house condition during two successive seasons of 2013/2014 and 2014/2015, at the experimental site of Central Laboratory for Agricultural Climate (CLAC), Agricultural Research Center, Giza, Egypt. The present study aims to determine the partial replacement of mineral nitrogen fertilization of tomato by nitrogen fixing bacteria with or without adding compost in sandy soil. Tomato seedlings (Lora F1Hybrid) were transplanted during the first week of October into plastic pots (30 cm diameter) filled with 10 kg of sandy soil. Three rates 25, 50 and 75% of the recommended mineral nitrogen in the nutrient solution for tomato with adding compostat 2% and nitrogen fixing bacteria (Azotobacter chroococcum and Azospirillium brasilense) at 20 ml/plant either individually or in combinationswere investigated on growth, mineral composition and yield of tomato plants compared to 100% of recommended nitrogen only (control). The plants were irrigated daily by drip irrigation and received 200 ml/plant of nutrient solution twice a weekly. The results showed that using 50 or 75% of N-mineral fertilizer + compost + nitrogen fixing bacteria gave the highest values of growth, mineral composition and yield of tomato. It is recommended that 50% of nitrogen mineral fertilizers for tomato plants could be replaced by nitrogen fixing bacteria in presence of compost, which in earn, reduce environment pollution caused by extensive application of mineral nitrogen fertilizers.

Mehaya, F. M. | Mohie M. Kamil | Ashoush S. | Khalil I.
Physico-chemical properties of honey and honey samples adulterated with glucose or sucrose were determined. Total soluble solids (TSS), pH and electrical conductivity of honey and its adulterated samples ranged between (84.10-84.50%), (3.80-4.63) and (11.73 – 232.32µS), respectively. Sensory properties of honey and its adulterated samples showed that, no differences in the sensorial properties were found in authentic honey and honey adulterated with 25% sucrose or 25% glucose. Increasing adulteration ratio to 50% glucose decreased taste, flavor, color and general appearance, while adulterated honey with 50% sucrose caused significant decrease in taste and general appearance. The possibility of using HPLC to detect adulteration of honey through determining their sugars content was evaluated. The obtained results indicated that, authentic honey was characterized with its higher fructose/glucose ratio (1.21) compared to adulterated honey samples (ranged between 0.35 - 0.94). FT-IR spectroscopic technique was used to evaluate honey quality. Reliability FT-IR for quantitative and qualitative analysis of sucrose, glucose and fructose were evaluated. The main FT-IR spectral bands of sucrose, glucose and fructose were identified at different concentration levels. The relationship between sugars concentration (sucrose, glucose and fructose) and its spectral bands absorbance (peak height) were evaluated to prepare sugars standard curves and their linear equations. Selected main peaks of sucrose, glucose and fructose provide the best calibration model with correlation coefficient (r2) higher than (0.9). Honey samples adulterated with glucose were characterized with specific spectral peaks, in which the absorbance was increased by increasing the ratio of adulteration with glucose at 1087, 1105, 1189 and 984 cm-1, while the adulteration with sucrose lead to increase in the absorbance of spectral bands of sucrose as 1054, 1149 and 984 cm-1 especially in honey adulterated with 50 % sucrose.
