Mostafa
Abstract Present investigation was conducted to study the genetic variability of some growth and flowering traits of branching mutant of Helianthus annuus (sunflower) plants that having many inflorescences per plant. This study was done during two successive seasons at the Nursery of Ornamental Plants, Faculty of Agriculture, South Valley University, Qena, Egypt.High broad sense heritability with high genetic variance( GCV% and PCV%) were found for number of inflorescences per plant, stem diameter, leave area, fresh weight of vegetative growth and 100 seeds weight. This result refer to the small amount of environmental effects and these traits are under the influence of genetic control. While high heritability in broad sense with moderate genetic variance were found for plant height. Whereas moderate heritability in broad sense with moderate genetic variance were found for number of leaves per plant, inflorescence diameter, number of seeds per mean head. So, Selection is an expected tool to improve branching mutant of Helianthus annuus plant characteristics.

Capillin produced from Artemisia monosperma family Asteraceae. Capillin has strong antifungal activity, and it is possibly antitumor. Capillin exhibits cytotoxic activity and causes apoptosis of certain tumor cells. The aim of the investigation is to study the effect of Capillin foliar spray on productivity and quality of sugar beet varieties under stress of salinity and lack of chemical fertilizers.In these trials no urea, no hormones no pesticides, no fungicides were used. More long shelf life of vegetables and fruits because plants treated with capillin are organic.
The experimental design was split-plot in (RCBD) with four replications. The main plots were devoted to varieties, whereas Capillin levels treatments were in sub-plots. The performance of four sugar beet varieties (cvs.); Samba, Pleno, Poly belga and Gloria was studied to estimate sugar yield and quality under the four Capillin levels.
The effect of Capillin levels was significant. Samba variety at 500 ppm Capillin level had the highest sugar extraction as well as sugar yield/fed. Using Capillin attained high productivity, ratio of sucrose productivity achieved up to 239 %.

First Record of Blister beetle Meloe rugosus M. (Coleoptera: Meloidae), as insect pest on some field crops in Farafra Oasis, Western Desert, Egypt
Wael
El-Sheikh
The blister beetle Meloe rugosus Marsham, ( Coleoptera : Meloidae ) was recorded for the first time as a serious insect pest attacking winter crops , particularly faba bean ( Vicia faba L.) and wheat ( Triticium aestivum ) in Farafra Oasis, western desert of Egypt. Beans, peas, alfalfa, Egyptian berseem, onion and the wild weed, Meliolotus indica L. were also recorded as host plants of this species. Adult beetles are phytophagous feeding plant foliage and flowers and under the stress of high population, plants may suffer death. Beetles occurred from early as November until late May. Through field observations in mid-January, the mating stage begins, where the male and female meet through the female sex pheromone. It was noted that the male searches for the female in the early morning, and when one of them meets the other, the mating stage initiate and the eggs are laid in the soil. During swarming and feeding, beetles secrete cantharidin fluid, a potent blister agent and long-term health threat to nearly all livestock feeding on plants hay. Field observations on insect behavior, eggs, crop damage, and activity and host plants were briefly explained.

Application of Some Fungicides Alternatives for Management Root Rot and Wilt Fungal Diseases of Marigold (Calendula officinalis L.).
Gomaa
Abdel-Wahed
Root rot and wilt diseases are widespread in Egypt causing severe yield losses on marigold (Calendula officinalis L.) plants. These diseases were detected in Beni-sweif governorate during surveying trials in 2017/2018 and 2018/2019 seasons. The isolated fungi were Fusarium subglutinans, F. oxysporum, F. solani, F.semitectum, F.nivale, F.roseum, Rhizoctonia solani, F. nivale and Pythium splendens which achieved the highest occurrence percentage in isolation trials from samples of Beni- sweif governorate. Fusarium. oxysporum was more virulent than the other fungi in pathogenicity tests on marigold. The effect of garlic and onion watery extracts , microelements,macroelements, Ascopine, Potasien, yeast ( Saccharomyces cerevisiae) and fungicides on marigold root rot and wilt diseases incidence were tested under in vitro and in vivo. These controlling agents, however, were varied in their positive efficiency against diseases. Fungicides were the superior treatments in controlling diseases and improving plant growth parameters. In the applied field experiments, all treatments tested significantly decreased the percentages of infection and increased the growth parameters compared with control treatment.

The study aimed to estimate the efficiency of resource use for farmers in the Sahel El-Tina region in Port Said Governorate by using a randomly sample of 140 farmers were selected from Sesame and Sugar beet farmers in the study area. They were selected according to the cultivated area of each crop. The cultivated area of Sesame crop reached about 29.11% from the total cultivated area, while the cultivated area of Sugar beet reached about 29.34% in study research. Data were collected by questionnaires through a personal interviews with the crops study farmers in the study area of both crops. The data were analyzed using the gross margin analysis, assessing the functions of production, costs and resource efficiency. The results for Sesame crop showed that the value of the determination coefficient reached 96.2%, which means that 96.2% of the factors affecting Sesame productivity (organic fertilizers, mechanical work and human labor). The gross margin was about 7600 L.E / feddan because the optimal use of agricultural resources. While the result for Sugar beet crop showed the value of determination coefficient factor increased reached 89.5%, which means that 89.5% of the factors affecting of the Sugar beets productivity are due to the influence of independent agricultural recourses. The gross margin was reached about 9140 L.E / feddan and the result of the use of resources showed that two of the agricultural resources (cultivated area and human labor were underutilized used , while(nitrogen fertilizers and mechanical work)were over utilized used .

The governorate of Kafr El-Sheikh is characterized by the production of varieties of rice is low in the soil. However, productivity is low compared to the average productivity in the Republic. The study aims to identify the efficiency of the use of agricultural economic resources in the production of rice crop in the study area in order to determine the extent of deviation of the actual production situation from the optimal production level and the maximum return. The study was based on estimating the production function of the rice crop using the Douglas Cobb function in the exponential form and estimating the cost function according to the cubic picture. The results of the estimated production function indicate that the most important explanatory variables affecting the average production of rice crop in the study sample is the automatic work and the amount of seeds in kilograms and the amount of chemical fertilizers as a unit of oil if the increase of these resources with the presence of other agricultural resources increase the average farm production of rice and calculate productivity The marginal value of these resources was found to be about 0.08466 tons, 0.00891 tons, and 0.00892 tons each, respectively.

This research aimed at: (1) Evaluating the linkages inside the agricultural innovation system in Assiut Governorate; 2) Identifying the critical information gaps and pathways inside the agricultural innovation system in Assiut Governorate; 3) Evaluating the information flow inside the agricultural innovation system in Assiut Governorate. The study was conducted on 77 respondents representing the seven studied components of the agricultural innovation system. Data were collected using questionnaire form during February 2020. Graph theoretical technique was used for data presentation and analysis. With regard to evaluating the linkages inside the system, the results indicated a low density of the linkages matrix (0.36), and it was also found that the agricultural extension component turned out to be the largest source of influence, while agricultural research is the most affected component inside the system. Regarding the information gaps and pathways within the system, it was found that agricultural extension and agricultural research were the dominant components, while farmers' organizations was the most subordinate component inside the system, as the research identified five important linkages (RH-RF-HF-EH- EF), and two important pathways (EHF- RHF) to be concerned about for better information streaming inside the system. As for the evaluation of information flow, it was found that agricultural extension was the main sender of information, while agricultural higher education was the main receiever of information among the components of the system. It also came out that the most needed components to be reformed inside the system were agricultural secondary education.
