This study was conducted to revise the taxonomic identity and clarify specific relationships among the studied Triticum species in Egypt. The studied species included; T. dicoccum (Schrank) Schubl.; T. dicoccoides (Koren ex Asch. & Graebn.) Aaron Sohn. T. tugidum L.; T. durum Desf.; T. pyramidale (Delile ex Schult.) Percival and T. aestivum L. Moreover, the wild Emmer Wheat T. dicoccoides (Koren ex Asch. & Graebn.) Aaron Sohn was recently found in Egypt as a new record. The genus Triticum L. includes 14 species, all of them are cultivated for food except the wild Emmer.

The study aims at estimating internal rate of return for the cultivation of date palms project in the new lands to encourage small investors and young graduates, to adopt projects of sustainable agricultural development under the assumption of change revenues and invested costs of the project. Also, explaining some productivity and economic indicators to produce dates in Egypt. The study showed that palm area, number of fruitful palms, palm productivity and the total production of dates annually increase at significant rates during the period of 1996 - 2010. The most important regions producing dates are Behera, Ismailia, 6 October, Aswan, New Valley, Matrouh and Noubaria zone. The most important cultivated varieties are Zaghloul, Samani, Meghal and Siwei. The study indicated that internal rate of return in the new lands as in Northern Sinai, Matrouh and the New Valley reached 28%. It was observed that decreasing total revenue up to 25% with increasing investment costs up to 25%, the internal rate of return is not less than 18%. So, cultivation of date palms is economically a profitable project. Thus, this project contributes to the horizontal agricultural expansion, reducing desertification, encourages some industries related to palm cultivation, creates new jobs, increases date export opportunities to overseas markets and increases agricultural income. Also, profits gained by young graduates are sufficient to pay annual premiums of received loans in addition to the interest of these loans, so that the left return is enough for their livelihood.

This study was carried out in Wadi EL- Technologia in Ismailia Governorate, Egypt, during 2010 and 2011 seasons. Washington Navel (N.O.), Valencia (V.O.) and Baladi orange (B.O.) trees budded on Sour orange (S.O.) and Volkamer lemon (V.L.) were grown in sandy soil under drip irrigation system from a well has salinty of (1100 ppm).This investigation aimed to study the effect of the two citrus rootstocks on vegetative growth, yield, fruit quality, leaf mineral content of the three studied scions as well as the effect of such scions on root system growth of both rootstocks. The obtained results indicated that, Volkamer lemon rootstock  recorded the highest significant values of vegetative growth, yield and fruit quality except  T.S.S% and ascorbic acid content . Sour orange rootstock gave the highest significant effect on values of leaf mineral content (N, P, K, Mg, Fe, Zn and Cu) however V.L. showed the highest significant value. while, Ca leaf content recorded insignificantly difference between both  rootstocks. Leaf Mn, content was significantly the highest with S.O. in both seasons. Root fresh and dry weight were the highest significantly with V.L. rootstock. From the showed result, one can recorded that V.O. scion significantly increased the vigour of V.L. root fresh and dry weight. While, B.O. scion showed significantly the lowest vigoure of V.L. root fresh and dry weight. On the other hand, N.O. scion gave a midiate result between V.O. and B.O. scions on root fresh and dry weight.

This study explored the opinions of central level extension employees about whether the Egyptian agricultural extension system needs to be reformed or not, and the alternatives they consider to be the best-fit options for extension in Egypt. The study covered 98 extension employees at the central level; findings show that all aspects of the Egyptian extension system are good candidates for reform and possible restructuring. These aspects could be ranked as financing, policy & organizational structure, staffing, and field operations as reported by 100%, 95%, 91%, and 68% of the respondents, respectively. Concerning the overall extension system, about 91% of the respondents reported that the Egyptian extension system is a good candidate for reform and possible restructuring. Findings also show that devolution, deconcentration, and delegation were the appropriate arrangements for extension decentralization as mentioned by 85%, 82%, and 55% of the respondents, respectively. Moreover, alternatives of providing and financing extension services were suggested and prioritized.
