The livestock in the New Valley Governorate are cows, buffaloes, sheep, goats and camels. The total livestock wealth in the New Valley Governorate is about 371.4 thousand heads, where the total number of cows is about 204.8 thousand heads. The highest animal density is found in the centers with the highest rates of rainfall, which allow the good growth of pastures, as well as the availability of low-salinity wells water. The New Valley Governorate is also considered a promising area for development. Its geographical location makes it free of epidemics and diseases that have recently infected livestock, along with the availability of ingredients and components for manufacturing feed at low costs, providing for the establishment and success of breeding projects in that governorate. However, despite the availability of components in the New Valley Governorate such as its geographical location and the abundance of groundwater needed for fodder cultivation and the vast areas of land for raising cows and buffaloes, it did not make the best use of it to increase the livestock wealth of these animals, to reduce the local production deficit of red meat, and not keep up with the increasing demand for it as a result of the steady increase in the population. In addition, there is a need to identify the characteristics of cows and the economic return of those characteristics, as well as conducting an economic evaluation of cow breeding projects in the Dakhla region in the New Valley Governorate based on modern scientific bases, to encourage the entry of investors into the field of livestock breeding. The importance of this study is being one of the economic evaluation studies of the production and breeding of cows according to modern scientific bases, where a sample of 50 cow breeders was taken by a simple random sampling method in the Dakhla region, (an average of about 25 cows/breeder). In order to find out some economic measures to evaluate the economics of cow production in the study area, quantitative analysis of some farm animals compared to cows was used. The study utilized the use of some economic measures for economic evaluation of the breeding and production of cows in the valley, where the sale takes place after the third year, and the use of dynamic programming as one of the modern methodologies compared to the traditional economic methods of the breeding and production of cows in the new valley. The results of the dynamic programming model were better compared to the traditional method of economic evaluation of the project, which encourages investors to enter the field of cow breeding and production in the New Valley, where the net return in the second year amounted to about 39.5 thousand Egyptian pounds (L.E.), at a rate of about 14.1 %, and to about 13","PeriodicalId":11430,"journal":{"name":"Egyptian Journal of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74955479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Res. Center, Egypt, to study the effect of weed control treatments on yield and yield components of some Egyptian bread wheat cultivars and its associated weeds. The experiments were laid out in a randomized complete blocks design (RCBD) with split-plot arrangement with four replications. The main plots were assigned to five bread wheat cultivars Misr-1, Misr-2, Shandaweel-1, Sids-14 and Giza-171, and seven weed control treatments (Pallas 4.5 % OD, Atlantis 1.2 % OD, Broadway-star 8.5 % WG, Liprator fort 36 % SC and Onostar 75 % WF ,followed by Traxsos 5% EC), as well as hand weeding twice and unweeded check were allocated in sub-plots. The results showed that the cultivars were significantly affected the dry weight of total annual weeds. The wheat cultivars were significantly different in yield and its attributes such as number of spike/m 2 , number of kernels/spike, 1000 kernels weight (g), harvest index (HI) % and grain yield (ardab/fad). The greatest value of grain yield was recorded by cv. Shandaweel-1. The highest competitive ability of cultivars (CAC%) and the least dry weight of total annual weeds was achieved by cv. Misr-2 and Giza-171. Also, the herbicides (Onostar followed Traxsos, Atlantis, Broadway star and Pallas) as well as twice hand weeding showed the highest reduction in dry weight (g) of weeds and the highest weed control efficiency (WCE%). While , the least effective herbicide was Liprator fort. The treatments of Pallas, (Onostar followed by Traxsos), Atlantis and broadway star as well as hand weeding achieved the highest increment in wheat yield and its components. The interaction effect between wheat cultivars (Shandaweel-1, Misr-2 and Misr-1) and the herbicides Pallas, Onostar followed by Traxsos showed the least dry weight of total annual weeds and gave the highest wheat grain yield followed Atlantis and Broadway star.

It was found that amending the sand with either clay or FYM compost at any ratio in these studies significantly improved all vegetative and root growth parameters, with the superiority of the mixture, sand + FYM compost (3:1 v/v), which gave the highest means of plant height, No. leaves/plant, root length and fresh and dry weights of shoots and roots compared to all the other media in both seasons. On the other hand, shortening irrigation period from 3 to either 2 or 1 days significantly hastened growth with the prevalence of 2 days irrigation interval that attained means higher, to some extent, than daily irrigation in most growth characters in the two seasons. So, the best vegetative and root growth criteria of Ochna plant were obtained from planting in the mixture of sand + FYM compost (3:1, v/v) with irrigation every 2 days. A similar trend to that of vegetative and root growth results was also occurred concerning chlorophyll a, b, carotenoids and total soluble sugars concentrations in the leaves . From such gains, it can be proposed to culture the small transplants of Mickey Mouse bush (Ochna serrulata) under shade in sand + formyard manure compost mixture (3:1,v/v) and watering them once every two days to speed growth of this slow-growing shrub during the incubation period in the nursery .","PeriodicalId":11430,"journal":{"name":"Egyptian Journal of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80765622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The importance of studying the organizational climate, is due to the influence of the organizational climate on the organizational behavior of the members of this organization, which affects the success of this organization in achieving its goals. The current article aims to evaluate an organizational climate instrument, and testing the goodness of fit of the proposed causal model. To achieve these goals, an organizational climate instrument was translated and prepared for testing in the Egyptian context. A causal model was also proposed to be tested. To achieve these goals; A sample of 140 employees of the organization of engineering of irrigation was selected in Gharbia Governorate. Multiple linear regression method was used to test the goodness of fit of the proposed causal model. The most important results indicated that the perceived organizational climate instrument used has excellent reliability and validity. Also, there is a high level of positive perception of the organizational climate among the respondents. The results also indicated that the variable of organizational material resources has the largest total causal effect on the perceived organizational climate in the revised model, as well as the variable of perceived organizational climate has the largest total causal effect on the variables of rate of performance of the formal job tasks and organizational ineffectiveness. Despite the high positive level of perceived organizational climate among the respondents, this positive climate does not reflect the rate of performance of the formal job tasks of these employees. The article suggests that necessary procedures should be taken from decision-makers to confront the high negative level of perceived organizational climate of the climate of planning and decision-making, the climate of career development ,and the climate of reward system.","PeriodicalId":11430,"journal":{"name":"Egyptian Journal of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78075521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
