A systematic random sample of 111 rural wives were personally interviewed by using a questionnaire to collect the data. The wives' attitudes toward More Children Reproduction were measured as a dependent variable by using a dichotomous measure. The discriminate analysis technique was used to compare between the two groups of the dependent variable. That is, approvals vs. oppositions considering 9 discriminating variables.      The results indicated that there were significant differences between the rural wives of the two groups regarding five discriminating variables. The discriminating variables explained 41.2% of the discrimination between the two groups. The classification results revealed that 81.1% of the rural wives were correctly classified according to the discriminating variables. The probability of group membership calculated by tau was reached around 62.2%.  }, keywords = {Rural Women's Attitudes Toward,Children Reproduction,Kafr El-Sheikh Village}, url = {https://jpd.journals.ekb.eg/article_42669.html}, eprint = {https://jpd.journals.ekb.eg/article_42669_1eeb075b7f9fd1f49a0bf1dd5afc1d81.pdf} } @article { author = {Shahin, Heba and Yasseen, Yasseen and Fahim, Mohamed}, title = {IMPROVED MICRO PROPAGATION OF Cichorium intybus L.

The pharmaceutical raw materials were obtained from wild chicory (var. Maurane). Currently, farmers are increasingly assuming plantations of wild chicory, and breeders are attempting to produce cultivars for medicinal purposes. In the modern breeding of chicory important feature is the ability to propagate in vitro culture. The aim of our study was to assess capacity of natural population of wild chicory for plant regeneration from leaf explants. In the first was examined the effect of various concentrations of BA and TDZ on the regeneration of shoots from leaf explants (0.5 cm2). After that, 25 plants were propagated on the medium which was found as optimal. Then, their callus growth and shoots regeneration capacities were compared. The majority of the shoots were regenerated from callus but direct organogenesis was also observed (8%). Shoot regeneration was found to be the most efficient on MS medium containing 5MµBA and 3MµTDZ –97% of the explants produced shoots, while the average number of shoots was 15.5. The wild chicory shoots rooted easily.  }, keywords = {Cichorium intybus,Regeneration,TDZ,BA,callus formation and 2,4-D}, url = {https://jpd.journals.ekb.eg/article_42778.html}, eprint = {https://jpd.journals.ekb.eg/article_42778_67cf0238adae56953067c08992c94760.pdf} } @article { author = {El Sadek, Ahmed and Bin-Isa, Mohamed}, title = {ASSESSMENT OF SUPPLY IN RESPONSE TO THE GRAPE HARVEST IN LIBYA DURING THE PERIODS (1990-2010)}, journal = {Journal of Productivity and Development}, volume = {20}, number = {2}, pages = {141-159}, year = {2015}, publisher = {Zagazig University.

The materials for this study consisted of six rice genotypes namely; Sakha101, Sakha102, Egyptian Yasmin, GZ1368s-5-4, IET1444 and IR78875-176-B2-B, These genotypes have a wide range of variation due to their different genetic background. The six rice parents were crossed to produce F­1 hybrid seeds of three crosses, namely, Sakha101 x GZ1368s-5-4, Sakha102 x IET1444 and Egyptian Yasmin x IR78875-176-2B. The six populations, P1, P2, F1, F2, BC1 and BC2 for each cross were utilized to determine the genetic parameter of the studied characters.  The results revealed that mid parent values (m) were highly significant in positive direction for all traits in all crosses, Moreover, additive effect was highly significant in negative direction for grain yield/plant trait in cross I, as well as, grain length, grain shape and amylose content % in cross II. In addition, dominance effect was played an important role in the inheritance of grain shape, and amylose % in negative direction and grain yield in positive direction in cross III. These results also indicated that all types of gene interaction were played an important role in the inheritance of all traits, according to the cross itself. The broad sense heritability was high for all traits, it was ranged between (85.51 and 98.73%) for 1000 grain weight in cross I and grain yield/plant in cross I, respectively. Moreover, low to moderate estimated values of narrow sense heritability were observed for all traits in all crosses, the highest value (32.5%) was recorded for grain shape trait in cross III. However, the great discrepancy between the estimates of heritability in broad and narrow sense for 1000-grain weight character was reflected in low estimates of dominance variance or high estimates of additive variance for this trait. In addition, low estimates of expected genetic advance (9.03 and 9.04) were observed for amylose %, and 1000-grain weight in cross I, respectively. Low to moderate expected genetic advance with low narrow sense heritability for amylose content % and 1000-grain weight could be expected because this trait is under polygenic control. Moreover, additive and dominance components of variation were significant in the inheritance of these traits, but additive component was higher than the dominance one. Conclusively, the results suggested that early generation selection may be effective in improving of these traits in cross I. On the other hand, the results also indicated that the selection in late generations will be improving grain shape in cross II and 1000 grain weight in cross III.    }, keywords = {rice,Inheritance,gene action,Yield components and Grain quality traits}, url = {https://jpd.journals.ekb.eg/article_42785.html}, eprint = {https://jpd.journals.ekb.eg/article_42785_82f0ff0fab1d5da1c7f5b9ff6f782dfb.pdf} } @article { author = {El Damasy, Ashraf}, title = {PROBLEMS FACING THE COMMUNITY DEVELOPMENT ASSOCIATIONS IN SOME VILLAGES OF ISMAILIA}, journal = {Journal of Productivity and Development}, volume = {20}, number = {2}, pages = {179-209}, year = {2015}, publisher = {Zagazig University.

This research was conducted in ten villages of Ismailia on a systematic random sample of beneficiaries ten associations of associations of the local community's development (1802) beneficiary distance Preview (6). Thus, the number of beneficiaries of the respondents reached (300) Researched, and (10) members of the Board of Directors of each of the studied Association associations bringing the number of respondents from the members of the Board of Directors (100) Researched and thus amounted to a total sample of 400 respondents. It was the collection of data for the study during the months of November and December (2014) by two forms of one interview, especially the members of the Board of Directors, and other private beneficiaries of the association's activities through a personal interview with each respondent, and study used duplicates, and percentages, and the arithmetic average in the description and presentation of data. The results of the study resulted in a number of the most  important: 1 - More than five studied associations play a development role is weak in the seven axes combined, and a quarter of the studied associations play a development role of the average in the seven axes combined, and five studied associations play a major developmental role in the seven axes combined, while nearly one-third of associations studied not carry out activities related to the turn in the seven developmental axes combined. 2 - It became clear that the average temperature of the community development association in turn in the seven developmental axes combined from the perspective of the beneficiaries of the association's activities has reached, the highest of the half as the overall average of between. So is the role of the local community development associations in whole performed moderately. 3 - The most important problems facing the associations of community development from the standpoint of members of boards of directors in descending order according to the percentages mentioned are: the weakness of financial resources and lack of fundin), and non-availability of the necessary support to carry out projects services, and lack of awareness among people's of the importance of participating own effort), and the lack of technical and administrative personnel to operate the association , and the lack of adequate training for board members and employees association, and the presence of some Subversive elements within the local community , and the difficulty of laws and regulations Organization of the work of the Assembly.   4 -Turned out to be the most important problems facing the associations of community development from the standpoint of beneficiaries in descending order according to the National percentages mentioned are: the weakness of the efficiency of the Board of Directors and staff association, and lack of adequate time of service to the public , nd lack of Assembly's ability to reduce unemployment and provide job opportunities for young people , and lack of adequate service provided by the Assembly to the needs of the public , and projects Association do not come back of great benefit to all residents of the village, and lack of Assembly's ability to provide material assistance to the needy.                               5 -It became clear that the most important proposals of the board members to overcome the problems faced by associations of local community development in descending order according to the percentages mentioned are: to provide the necessary support for the establishment of projects and services , and increase the training courses to create the technical and administrative personnel to operate the association ,and reduce the ongoing official bodies in the scope of work of the Assembly interventions , and coordination between the work of the Assembly and other organizations ,and the elimination of destructive elements within the local community ,and the need to facilitate legislation and laws governing the work of NGOs .                                                                            6 - The most important proposals of beneficiaries to overcome the problems faced by associations of local community development in descending order according to the percentages mentioned are: raising the level of efficiency of the Board of Directors and staff association ,and determine the appropriate time to provide the service to the public ,and the need for the introduction of a cadre of men Business on the board to help with funding and establish service projects create jobs for young people , and the need for matching projects and services to the needs of the necessary community , and work on the deployment of development thinking among the people of the village .                                 7 - The study recommends the need to the attention of officials in all ministries in the state associations of local community development and solving problems which hampered in its role developmental in the Egyptian countryside, because it acts as a complement to most government institutions in the implementation of development programs, and allocate the state as much as from the general budget to increase funding for these associations to help in the implementation of their activities and continue to play their role in the community service.                }, keywords = {Problems Facing,Community Development Associations,Villages,Ismailia}, url = {https://jpd.journals.ekb.eg/article_42787.html}, eprint = {https://jpd.journals.ekb.eg/article_42787_648e46827ae7a41a020e3f729619aaa2.pdf} } @article { author = {Salem, Khaled and Ayoub, Abou bakr and Yassin, Yassin and El-Abd, Abdl moety}, title = {BREEDING STUDIES ON SOME AGRONOMIC AND QUALITY TRAITS IN RICE(Oryza sativa L.)}, journal = {Journal of Productivity and Development}, volume = {20}, number = {2}, pages = {211-226}, year = {2015}, publisher = {Zagazig University.
