Abstract: During 2017 and 2018 seasons, mango CVs. Sadek and Zebda were treated with potassium silicate one, twice or thrice at 0.0 to 0.4%. One spray was carried out at the last week of Feb. Two sprays were conducted at last week of Feb. and Last week of Mar. Three sprays were conducted on the last week of Feb. and one month intervals. The merit was adjusting the best concentrations and frequencies of application of potassium silicate (25% Si + 10% K₂O) responsible for improving fruiting in such CVs. Using K- silicate once, twice or thrice, at 0.1 to 0.4% materially was accompanied with improving growth, photosynthetic pigments, nutrient, yield and fruit quality characteristics relative to the control. Increasing concentrations of K. silicate from, 0.2 to 0.4% and frequencies of application from twice to thrice had no considerable promotion on aforementioned parameters. Mango cv. Sadek recorded higher values of all the investigated parameters than other cv. namely Zebda. For promoting, yield and fruit quality of Sadek and Zebda mango cvs, it is suggested to spray the trees twice with K- silicate at 0.2%. Planting Sadek mango cv was preferable than cultivating mango cv Zebda under upper Egypt conditions according to its higher yield and better fruit quality.

Abstract: During 2015 and 2016 seasons, Wonderful pomegranate trees received two sprays of three potassium compounds namely mono potassium phosphate, thiosulphate potassium and merstim vesting compound as a source of potassium and apple vinegar. Spraying was done twice at first bloom and again at 5% fruit colouration. The scope was detecting the best source of K as well as the effect of apple vinegar on fruit colouration and physical and chemical characteristics of the fruits. Single and combined applications of K- thiosulphate at 0.4%, mono- K- phosphate at 1.0%, Merstim vesting at 0.3% and apple vinegar at 0.2 to 0.4% were responsible for promoting fruit colouration % and improving fruit quality in terms of increasing T.S.S.%, total and reducing sugars %, T.S.S./ acid, total anthocyanins in fruit peel and aril and ascorbic acid and decreasing total acidity %, juice p H and total phenols and total soluble tannins in fruit peel and aril over the control. The best K compounds in this respect were K- thiosulphae, mono- K phosphate and Merstim vesting in ascending order. Using different K sources materially surpassed the application of apple vinegar in this connection. The best overall treatment was eth application of Merstim vesting at 0.3% besides apple vinegar at 0.4%. Treating Wonderful pomegranate trees twice at first bloom and again at 5% fruit colouration with a mixture of apple vinegar at 0.4% plus mono K phosphate at 1% gave the best results with regard to fruit colouration and fruit physical and chemical characteristics.

Abstract: During 2016/ 2017 and 2017/ 2018 seasons, Williams banana plants were treated with carboxylic -Ca and glycine each at 0.1 % as well as Algae extract at 0.05 to 0.2% either singly or in all possible combinations. Plants received three sprays at the first week of May and at one month intervals. The objective was examining the impact of these materials on vegetative growth aspect, plant nutritional status, bunch weight and fruit characteristic of Williams banana plants. Subjecting Williams banana plants thrice with carboxylic -Ca and glycine each at 0.1% and Algae extracts at 0.05 to 0.2% singly or in combinations had considerable promotive effect on all growth aspects, N, P, K, Mg, bunch weight as well as all quality parameters. Using glycine was materially superior than using carboxylic -Ca in this respects. Using all materials together gave the best results. For promoting yield and fruit quality of Williams banana plants grown under Minia region conditions, it is suggested to use a mixture of Algae extract, carboxylic -Ca and glycine each at 01% thrice at are the first week of May and at one month intervals.

Abstract: Maturation date, yield / vine, berries colouration % berries, shattering %, cluster weight, total anthocyanins and both physical and chemical characteristics of grapevine cv., Flame seedless, Red Globe and Crimson seedless grown under Minia region conditions in response to treating the clusters with protone (10% ABA) at 250 to 1000 ppm, ethrel at 250 ppm and amino acids at 1 % either applied alone or in different combinations were investigated during 2017 and 2018 seasons. Single and combined applications of protone at 250 to 1000 ppm, ethrel at 250 ppm and amino acids at 1% once to veraison stage when approximately 10% of the berries on 50% of the clusters had softened resulted in measurable advancement in maturation date and promotion on berries colouration and berries quality compared to the control. In ascending order the best materials in this respect were amino acids, protone and Ethrel. Combined application were favourable than using each material alone in hastening fruit maturation and improving berries quality. Yield as well as weights of cluster and berries were unaffected by the present treatments. The most early in maturation date grape cvs could be arranged as follows in descending order Flame Red Globe and Crimson. The best results with regard to berries quality parameters were recorded on grapevine cvs crimson seedless, Flame seedless and Red Globe, in descending order. For solving the problem of uneven colouration of the berries in the clusters of Flame seedless, Red Globe and Crimson seedless grapevines grown under Upper Egypt region conditions, it is suggested to subject the clusters once at veraison stage when approximately 10% of the berries on 50% of the clusters on each vine had softened with a mixture of ethrel at 250 ppm, protone at 500 ppm and amino acids at 1%.

Abstract: The need to move cassava from poverty alleviator to industrial crop and ensure sustainability in cassava production, necessitated the need for fertilizer application to maximize yield. Applying organomineral fertilizer without adequate recommendations can result in low crop yields compared with potential yields. Using 30 kg pots, experiments were conducted in a completely randomized design to compare the effects of Pacesetter organomineral fertilizer (0, 50, 100, and 150 kg N/ha) and NPK 15-15-15 (400 kg/ha) on the performance of cassava (TMS 30572). Their residual effects were also evaluated. Cassava was planted one hard stem cutting per pot. The data obtained were subjected to analyses of variance with significance level at 5%. Pacesetter organomineral fertilizer (POF) increased cassava plant height, stem diameter, number of leaf and estimated average leaf area with the highest values obtained at 100 kg N/ha. The POF application at 100 and 50 kg N/ha, significantly increased cassava storage root yields compared to 150 kg N/ha or the control. These levels were not significantly different from the effect of NPK on cassava storage root yield. The order of the effects of fertilizers on cassava storage root yield is 100 > 50 > NPK > 0 > 150. Further, 100 kg N/ha POF significantly improved cassava storage root sizes compared to other treatments. Significantly higher top: storage root ratio was observed at 150 kg N/ha treatment compared to 50 or 100 kg N/ha POF treatments. There was no significant residual effect of fertilizers on subsequent cropping. However, the residual effect of 150 and 100 kg N/ha POF were 24.64 % and 9.11 %, respectively higher than the value observed using NPK fertilizer. Hence, 100 kg N/ha is recommended for optimum cassava storage root yield in the area.

Abstract: This study was carried out during 2015 / 2016 and 2016/2017 seasons to elucidate the effect of five grape rootstocks namely Freedom, Salt Greek, Paulsen, Rechter and Harmony on growth and vine nutritional status of two grape scions namely Flame seedless and Superior grown under middle Egypt conditions. The best rootstocks towards growth and nutritional statues for Flame seedless grape scion were Freedom, Salt Greek, Paulsen, Rechter and Harmony, in descending order and for Superior grape seicon were Salt Greek, Freedom, Rechter, Paulsen and Harmony, respectively. In conclusion, it can be recommended to use Freedom and Salt Greek as good grape rootstocks for Flame seedless and Superior grapevines, respectively, since such two rootstocks have high compatibility and improve growth and vine nutritional status of grape scion. Meanwhile Harmony grape rootstock is not acceptable for both grape scions.

Abstract: The reticulate Knife fish, Papyrocranus afer, is becoming important in fisheries because the juveniles are used as ornamentals. This study describes diet, diet overlap and feeding strategists of (juvenile (≤21.9cm), sub-adults (22 – 33.9cm) and adults (≥40.0cm) P. afer inhabiting Lekki Lagoon. Stomach contents analysis of stomach revealed P. afer exhibited dietary shift from predominantly micro-crustacean feeding in juveniles through insectivorous sub-adults and polyphagous feeding in adults. Schoener’s indices of diets overlap between parallel size-classes (adult-sub-adult; juvenile-sub-adult) were biologically significant (>60%); indicating that these size classes exploit similar resources. The Amundsen plots showed thst P. afer exhibited specialist feeding on decapods crustacean and insects at juvenile and sub-adult stages respectively. Adults were generalists’ feeders on insects, zooplankton, gastropods and fishes. The dietary items for Papyrocranus afer showed carnivorous and predatory habits for the species. This carnivorous habit implied that P. afer may require high protein diet during culture.

Abstract: Fermat's theorem has been dialectically verified by more than three hundred years of history and multi-personal conjecture. Unfortunately, there is only a difference between the inequality and the equation, and no integer expansion of compatibility is found. The conclusion is unfair. Defining group algebraic closed chains is an ordered combination set and equilibrium of finite finite-dimensional matrices of infinite elements, proving its unity, reciprocity, isomorphism, parallelism, limit theorem, and considering scalability, security, and decentralization. The superiority of chemistry, the logarithm of the dimensionless quantum function is established, and the arithmetic operation between [0~1] is realized, which is called the logarithm theory. It is convincingly proved that any inequality is an integer equality expansion, and it is proposed to prosecute Bug damage and solve the impossible triangle idea. The circular logarithm theory is proved by the "angel particle" of the physical experiment. In the actual project, there are innovative inventions for asymmetric energy such as earth electromagnetic field generators, gravity field engines, and turbojet engines.

Abstract: The objective of this study was to evaluate some hormonal treatment protocols to fertility improvement on repeat breeder Frisian heifers. A total of 36 Frisian heifers failed to conceive after 3-4 services (repeat breeder heifers) was used in this study. Results showed that pregnancy rate was higher significantly in G3, 83.3% than in G1, 50% and G2, 58% in repeat breeder heifers. Progesterone (P4) concentration in G1 or G2 was significantly (P<0.01) lower at artificial insemination (estrus) in pregnant heifers than in non-pregnant, while it was higher post-treatment 5, 10, 12 and 24 days post-artificial insemination in pregnant than in non-pregnant repeat breeder heifers. But, P4 concentration not significant during pre-treatment in all animals. At estrus concentration of P4 were lower significantly in pregnant 0.284, 0.392 and 0.246 ng/ml in G1, G2 and G3, respectively than in non pregnant in 1.356, 1.635 and 1.835 ng/ml, respectively. In G3, P4 concentration pre- and during treatment tended to be similar in pregnant and non-pregnant repeat breeder heifers. The P4 concentration on day 5, 10, 12 and 24 post-mating was significantly (P<0.001) higher in pregnant than in non-pregnant heifers in G3. The economic evaluation indicated that hCG at insemination and at 5 days post- insemination protocols had the cheapest cost (L.E 22/animal), while hCG-PGF₂α-hCG timed AI protocol showed the highest cost (L.E 64/animal).

Abstract. This research paper looks at how the State Oil Company of Azerbaijan (SOCAR) has been expanding its operations abroad, with a particular focus on the recent investments in Turkey. Empirical data on the investments of SOCAR is embedded in the theoretical discussions on the interlinkage between the interests of states and the oil companies, shedding light on what benefits investments abroad bring in for the country of origin of the companies as well as the host countries. Among others, it is an important question to ask how the oil companies contribute to their country of origin both in terms of strategic and economic interests.
