The present study aimed to extract the mucilage from Tamarind Tamarindus indica L and studying some the functional properties . The values of solubility , water binding capacity and viscosity for tamarind seed mucilage were:  87.4 , 17.54 and 13.7 respectively . The tamarind seed mucilage showed varied oil binding capacity from 0.42- 0.73 ( g oil / g dry mucilage ) due to the type of oil used . The results showed a higher emulsification stability from tamarind seed mucilage. This results indicated the ability of using tamarind seed mucilage as stabilizer and emulsifier in food industry .

This laboratory study aimed to evaluate the efficiency of two biological agents Beauveria bassiana (Bals) and Bacillus thuringiensis (Kursaki) and four chemical pesticides Levo 2.4 SL, Aster 20 SL, Difuse 450 SC, and Matrixine Plus EC on four important main pests that infect tomato plants. The pests studied were whitefly Bemisia tabaci (Hemiptera: Aleyrodidae), Meyrick Tuta absoluta (Lepidoptera: Gelechiidae), Sulzer Myzus persicae (Hemiptera: Aphididae) and Koch Tetranychus urticae (Acari: Tetraanychidae). The results show that the pesticide Matrixine Plus recorded the highest average of mortality of both larval and adult stages of all four pests. The average of mortality for adults and larvae of whitefly were 96.67% and 86.67% respectively. The average of mortality for adults and larvae of Meyrick was 93.33% for both stages, while the percentages for adults and larvae of Sulzer and Kotch were 96.67% respectively after seven days of exposure. The lowest averages of mortality were recorded for Antario on whitefly adults and for Difuse on whitefly (both (16.67%). Difuse caused the lowest average of mortality (26.67%) on Meyrick adults, whereas Antario caused the lowest average of mortality of 20% on Meyrick larvae. The results show also that Antario caused the lowest average of mortality of 23.33% on adults and 16.67% on larvae. Similarly, Difuse was recorded the lowest average of 20% on adults while Antario caused the lowest average of mortality of 26.67% on larvae after one day of treatment.

This study aimed at identifying the most important factors affecting bee honey production, by performing a comparative study for the economic efficiency and the technical efficiency, data were obtained from field sources in light of a random sample constituted a percentage of 5% taken from honey producers from 51 apiaries at the season of 2018- 2019. The research, in estimating economic efficiency and dividing its components into technical and allocative efficiencies, adopted the data envelopment analysis using the model of entry orientation in light of fixed and variable returns in checking the technical efficiency, and in light of variable capacity return  in checking allocative efficiency and cost efficiency, where we note that technical efficiency varied between (0.1-1) with an average of 27%, i.e. the sample is capable of increasing its production by 73% to reach the optimal volume, whereas we note that 96.3% of beekeepers are working with increasing capacity return. The technical efficiency, in light of the variation in capacity return, has varied between 0.5 minimum and 1 maximum with an average of 0.60, and that the apiaries which fell on the possible production curve were 12%. The economic efficiency on the other hand, reached an average of 0.46 and that means the bee breeding farms could achieve the same production level in light of costs reduction of 54%, i.e. capable of producing the current amount using only 46% of the economic resources, and this is attributed to the inadequacy of the allocative efficiency and the improper use of resources. The study recommended the use of amounts that realize the economic efficiency and, the redistribution of resources in a way that guaranties achieving the same level of production or more in light of costs reduction.

Half diallel crossing among five inbred lines of maize was  performed to estimate the combining ability effects and some genetic parameters. The crosses differed significantly for all the studied traits. Also, GCA and SCA mean squares were significant. The ratio GCA/SCA exhibited values under one indicating that non-additive gene action mainly controls the expression of all the studied traits. Inbred line 4 contributed significantly to the good performance of the hybrids for grain yield traits. Also, inbred line 5 exhibited desirable GCA effects for five traits and it seems to be promising. The crosses 2x4, 1x4 and 3x5 own highest mean and SCA effects for grain yield.

Glimpse of fish as perishable staple was reviewed. Fish is an important animal protein as it supplies good quality protein, vitamins and minerals. It is however highly perishable and spoils quickly, bad fish handling after harvesting, inadequate storage and processing facilities also contributes to fish spoilage in developing countries thus causing a lacuna between fish demand and supply, thus posing a great challenge to food security. Processing of fish facilitates its maximal use as for value-added fish products. Smoking is the preservation method most adopted in many developing countries to extend fish shelf life. Fish post-harvest loss come in different faces including: physical loss, quality loss and market forces loss all of which will lead to reduction in fish shelf life. Antimicrobial properties of plant extracts and proper packaging can extend fish shelf life. There in need to encourage women participation in fisheries subsector as their active role is essential to fighting poverty and ensuring food security within many households.

The quality of Heteroclarias with increased storage time using Quality Index Method (QIM) was evaluated. 140 live samples of Heteroclarias (average weight 230 + 7g) were used for the study. QIM was used to evaluate the key parameters in fish deterioration, twenty semi-trained assessors was used for the sensory evaluation. Data obtained were subjected to appropriate statistical tools using SPSS 16.0 version. Quality Index (QI) of Heteroclarias increases with increased post slaughter time when the fish was left at ambient temperatures (27 + 3°C) indicating decrease in fish quality with time. High correlation of (r=0.993) with a high coefficient of determination (R2=0.986) was obtained indicating that 98.6% of the variation in post slaughter time was explained by quality attributes; the regression equation was significant F(9, 130)=1080 (p<0.0001) indicating that it could be used for prediction and estimation of fish quality, the QI used in this study is therefore recommended to be used by relevant agencies for predicting fish quality.
Practical Applications :Fish is highly perishable despite its nutritional value, consumers becoming increasingly interested in the quality of fish they consume and the physical attributes of the fish is very vital for on the spot assessment of fish quality. This study provide quality index that could be used for prediction and estimation of fish quality using sensory evaluation.
