The main objectives of this research were: planning an extension program for farmers in the field of operation and maintenance of the drip irrigation system, by determining the level of farmers 'knowledge, conviction, and implementaion of the extension recommendations for the operation and maintenance of the drip irrigation system. It also aimed to determine the level of farmers' knowledge of the basic information about the drip irrigation system. Data Were Collected Using a Personal Interview Method by Questionnaire Prepared for this Purpose, for a Sample of 125 farmers, Frequencies, Percentage, and Spearman Rank Order Correlation Coefficient, were Used for Data Presentation and Analysis Using SPSS Program.The main findings can be summarized as follows: 44.0% of the farmers are between 37 and 53 years of age. 49.6% of the surveyed farmers are farm size between 3 -› 6 acre. 60.8% of the farmers have a number of years of experience in extension work ranging from 2 to 16 years. 55.2% of the farmers use the information resources as an average. 57.6% of farmers their knowledge level are ahigh basic information about the drip irrigation system. 64.0% of farmers their knowledge level are a medium of extension recommendations for the operation of the drip irrigation system. 52.8% of farmers their knowledge level are a low of extension recommendations for the maintenance of the drip irrigation system. There is a positive correlation between the of farmers knowledge level of extension recommendations for the operation and maintenance of the drip irrigation system., and between age, farm size, and use of sources of information, at a significant level of 0.05. while a level of 0.01 significance, with the benefit of information sources

This study was carried out during two winter successive seasons 2017/18 and 2018/19 to determine the effect of salinity stress on yield and yield components in F3 and F4 segregating populations of the two bread wheat crosses (Sakha 93 x Gemmaiza 9) Cross1 and (Sakha 93 x Giza 168) Cross II. The results showed highly significant differences between means of the two crosses and families for most the traits in F3, and 100 grain weight in F4 generations. The differences between salinity levels were highly significant for all traits in both F3 and F4 generations. The interaction between crosses × families was highly significant for all traits, except for number of grains/spikes in F3, while it was highly significant for number of grains per spike and weight of 100 grain in F4. The interaction between crosses × salinity levels was highly significant for all traits in F3, while it was highly significant for weight of 100 grain in F4. As for the interaction between families, salinity levels were highly significant for most traits in F3, while F4 were highly significant for weight of 100 grain. The interaction between crosses × families × salinity levels, were highly significant for most traits in F3, while in F4 were highly significant for weight of 100 grain. Highest values of H and GA were found for grain yield / plant and weight of 100 grain under salinity conditions in F4 generation. These traits would be improved by direct selection under saline soil conditions.

This research aimed to: (1) Determine the level of knowledge and implementation of the respondents' beekeepers of good beekeeping practices, (2) Determine the correlation between the level of knowledge of the respondents' beekeepers of good beekeeping practices and the studied independent variables, (3) Determine the correlation between the level of implementation of the respondents' beekeepers of good beekeeping practices and the studied independent variables. Data were collected using questionnaire form prepared for this purpose, from a Sample of 111 beekeepers. Frequencies, percentage, and Spearman rank order correlation coefficient were used for data presentation and analysis. The results showed that the level of knowledge of the respondents was high in four of the processes related to good practices in beekeeping, namely: visiting the hive, transferring the hives, joining the hives, and artificial fertilization with rates of 65.4%, 42.3%, 35.2%, 33.3% respectively. It also came to clear that the level of implementation of the respondents was high in one of the operations of good practices in beekeeping, which is visiting the hive by 36.0%, while their level of implementation was non-existent in four other operations, namely: industrial shunting, joining the cells, and feeding the colonies, and cell migration at rates of 49.5%, 39.6%, 35.1%, 33.3%, respectively. It came out that there is a positive significant correlation at 0.01 level between the knowledge level of the respondents about good practices of beekeeping and two variables: the use of information sources, and benefit from information sources, and a negative significant correlation at 0.05level between the respondents' knowledge level and average cell production. It came to light that there is a positive significant correlation between the level of respondents' implementation of good beekeeping practices, and two variables: use of information sources, benefit from information sources, and the number of years of experience, and a negative significant correlation at 0.05 level between the overall implementation level and average cell yield.
