Abstract:Noug (Guizotia abyssinica (L. F.) Cass.) is an important oilseed in Ethiopia. Genetic improvement of the crop is largely dependent on the scale of genetic variability. The research was conducted in the experimental field of Holetta agricultural research center main station and Ghinchi sub-center during 2016. The research trial was laid out in randomized complete block design and thirteen quantitative traits were recorded. Seventeen advanced lines of noug were studied for genetic variability and association of traits. The combined analyses of variance revealed highly significant (p < 0.01) differences among the genotypes for all the studied characters except for days to maturity and oil yield. The genotypic coefficient of variation ranged from 1.4 % for oil content to 23 % for oil yield while phenotypic coefficient of variation ranged 1.3 % for oil content and days to maturity to 17 % for shattering. The broad sense heritability varied from 16.5 % for oil yield to 91.7 % for oil content. The expected genetic advance as percentage of mean ranged from 1.5 % for days to maturity to 31 % for shattering. High heritability estimates along with high genetic advance was observed for seed filling period and shattering; Correlation studies revealed that seed yield was positively and significantly correlated with seed filling period and oil yield at genotypic and phenotypic level. The study indicates the presence of ample variability among the tested genotypes which implies the possibility of the crop for future improvement.

Abstract:Peach is a ‘climacteric’ fruit which is a very perishable and deteriorates quickly during storage and that is why it is marketed immediately after harvest. The main causes of this loss can be physiological as well as physical. Therefore the objective of the review is to assess techniques of postharvest storage of peaches. Several techniques were used in extending the storage life by maintaining the quality of peaches so far worldwide. Cold storage reduces the respiration rate of the fruit and hence ripening, senescence and decay development. However, chilling injury (CI) limits the storage life of peaches and nectarines under low temperature. Modified atmosphere packaging during marketing and storage of highly perishable commodities has similar results. The low relative humidity around non-packaged fruits could be the main cause for rapid deterioration of the fruits due to moisture loss, which result in shriveled and brownish fruits. Postharvest application of calcium may delay senescence in fruits with no detrimental effects on consumer acceptance. Exogenously applied calcium able to reduce fruit softening and increases storage life as compared to untreated fruits.1-MCP can also inhibit the ethylene action by blocking the continuously forming receptor sites on the plant cell and would not allow ethylene to bind on to receptor site.1-MCP treatments may differ by the ripeness stage of the fruit, concentration, treatment time and temperature. Therefore integrated use of these techniques can extend the shelf life of peaches tremendously by maintaining physical as well as chemical qualities.

Abstract:This research was conducted in Wad Banda locality, West Kordofan state- Sudan during 2018/2019. It aimed to identify the current status of Gum Arabic tree (Hashab) under practice of selective cutting and to find out effects of selective cutting of Hashab trees on farmland, crop yield, wind speed and rainfall based on farmer's perceptions. It also aimed to investigate the causes of farm land degradation in the area. Primary data was collected through social survey where in-depth interview was conducted. Fifty eight farmers who practice selective cutting were interviewed. Secondary information was collected from relevant references, annual reports and scientific publications. The data were descriptively analyzed where averages, percentages were calculated in Statistical Packages for social Sciences (version 16.00) and Microsoft Excel (2008) Programs. The results found that more than 50% of respondents indicated that Hashab tree increased last ten years. The total area targeted to be cut by all (85) farmers was 355 feddan (149.1 ha) with an average of 4.2 feddan (1.8 ha) per farmer. The proportion of felling in 2018 was 12.9%. There were 87.1% of respondents stated that selective cutting of Hashab trees does not have much effect on the farmland and 92.9% of respondents said it does not negatively affect crops yield but it increases the wind speed according to 98.8%. The main reasons caused farmland degradation were overcutting and overgrazing. Pearson Correlation analysis revealed that there was positive correlation (P≤0.08) between respondent’s perception and importance of selective cutting however, it is weak. The majority (84.7%) of respondent assured role of the Forest National Corporation in protection and encouraging people toward plantation. The study recommended declining the selective logging to the minimum level (≤5%) and organizing it. It also recommends activating forest laws and controlling grazing system.

Abstract:Insecticide chemicals can provide effective control of bruchids on pulses. However, small-scale farmers commonly do not use insecticides. In addition, dependence on insecticide chemicals is discouraged because of health and environmental hazards associated with their use. For more effective, safe and sustainable pest control integration of different compatible options is desirable. Use of resistant crop varieties is the most important component of integrated pest management strategy. The result of this study shows that to control the bruchids most of the botanicals are relatively, inexpensive, simple to apply, safe to the environment, animals and plants. They are easily avail to the farmers, adopted readily and integrated with other pest management practices. However, further research is needed on non-target effect and effective rate and frequency determination among others.
