The trial was carried out at the Holetta Agricultural Research Center with four almond varieties arranged in RCBD and three times replicated. Ferraduel had the highest tree height of 129.58 cm in the first growing season of 2011, followed by Desmayo (108.75 cm), Ferragnes (96.17 cm), and Marcona (95.56 cm). The Ferraduel variety has the highest recorded height except in 2014 and 2015. Annual growth differed significantly between years, with 2015 recording the most (42.7 cm) and 2013 following closely after (32.8 cm). The cross-sectional area of a tree trunk increased in general as the growth season progressed. In 2011, Marcona had the lowest TCSA (2.04 cm 2 ), whereas Ferragnes (86.58 cm 2 ) had a much lower TCSA in 2016. The exponential canopy stretch was somewhat limited from 2012 to 2013. The growing season 2016 has the most main branches, followed by the growing season 2013, with the values of 3.44 and 3.14, respectively. While the 2014 growing season had the fewest major branches, followed by the 2015 growing season with values of 2.19 and 2.58, respectively. Across all growing seasons, the Desmayo variety exhibited the highest branching height. With increasing tree height, TCSA and canopy stretch grow linearly. It also shows non-linear positive correlations of 0.43 and 0.35 with yearly growth rate and branching height, respectively.","PeriodicalId":137891,"journal":{"name":"Advances in Life Science and Technology","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124079399","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}

Bulb crops are among largely produced which are characterized by a shallow root system and underground vertical shoots. They are also cool season crops, and their growth and production are influenced by water, nutrients, radiation and carbon-dioxide. Factors that determine their water use efficiency are tillage, stage of the crop, evapotranspiration, irrigation, soil types and elevated co 2 . Nutrient use efficiency of bulbs also influenced by factors like soil factors, fertilizer factors, plant factors, agronomic consideration, biological consideration and climate factors. Nitrogen, phosphorus and potassium are the major consumed nutrients of bulbs. Radiation use efficiency of the bulbs also the key determinant of photosynthesis, photorespiration and respiration. Indicators of radiation use efficiency of bulbs are dry matter production, leaf area index and specific leaf area, ground cover, radiation interception and absorption, maintenance respiration of bulbs and dry matter partitioning. Another essential substrate for photosynthesis of bulb crops is co 2 and the main factors that determine co 2 use efficiency of bulbs are temperature and light. So as different studies indicated that for best production of bulb crops water, nutrient, radiation and co 2 use efficiency of them and the respective determinant factors should be considered and optimized.","PeriodicalId":137891,"journal":{"name":"Advances in Life Science and Technology","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124025058","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}

It is important in the daily Ethiopian diet. It is widely produced by small farmers and commercial growers throughout the year for local use and export market. No strong study has been conducted to evaluate the suitability of onion cultivation in Biyo Awale district of Diredawa. Hence, the present experiment was conducted to study the performance of improved varieties of onion for their suitability for cultivation in Biyo Awale district of Diredawa. The study was carried out during 20182019 cropping season to test the performance of onion varieties. Five high yielding onion varieties were planted in complete randomized block design experiment with three replications including local check at farmer’s field. The quantitative data on bulb yield, plant height, bulb size and number of leaves of onion varieties were collected. Harvesting was done and weighed when all onion varieties reach maturity (90% tops down). The results revealed that the tested onion varieties differ significantly for leaf length, leaf number, neck diameter, bulb diameter, average bulb weight and bulb yield. Among the varieties Bombay red and Melkam produced higher bulb yield (25.56 and 21.13 t ha) and gave 140.68% and 98.96% yield advantage over local check varieties, respectively. Therefore, Bombay Red and Melkam varieties were recommended to the study area and similar agro-ecology.","PeriodicalId":137891,"journal":{"name":"Advances in Life Science and Technology","volume":"139 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133765490","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}

In adopting the information technology innovativeness, information technology readiness plays a crucial effect. Misunderstood organizational characteristic within information technology innovativeness may generate unrealistic or inaccurate outcomes. Unfortunately, the effect of organizational context is nearly ignored in information technology innovativeness literature. In response, using the Resources based view (RBV) and Diffusion-Innovation-Theory (DIT), this paper argues on the interaction between the influence of organizational characteristic (information technology readiness), so as to explain information technology innovativeness. This proposition could improve understanding the information technology innovativeness and help to resolve inconsistency of findings in the literature. This study investigate the level of government information technology innovativeness in local through makers and managers by investigating the relationship between technology readiness and government information technology innovativeness.

Onion is one of the major economically important vegetable crops grown under irrigation in central rift valley. The field experiment was conducted at Melkasa agricultural research center during the dry season to identify conventional furrow irrigation and irrigation application level with and without mulch that maximizes productivity of onion per unit of water consumed and enhanced onion crop production. The experiment was carried out using RCB design having six treatments with three replications. The FAO’s recommended allowable Manageable depletion level of onion is 100%. In this study 75%, 100% recommended and 125% were tested. The analysis of variance for the result of the study indicated highly significant (P ≤ 0.05) differences for yield, yield components and WUE’s. The highest yield of 320.7 ton/ha was obtained from the 75% MAD with mulch which was not significantly (P≤0.05) different to the 100% MAD irrigation level. In terms of irrigation and water use efficiency, 75% MAD irrigation level application gave the highest IWUE which was significantly different from all other treatment combinations. Yield and water use efficiency based comparison had shown that there was significant difference between the yield, CWUE, and IWUE obtained in the treatment. Therefore, it can be concluded that increased water saving and associated water productivity through the use of 75% MAD with Conventional furrow irrigation and mulch, can solve problem of water shortage which improve WUE without significant reduction of yield. 75% MAD irrigation level water applied system and mulch appears to be a promising alternative for water conservation and labor saving with negligible trade-off in yield.","PeriodicalId":137891,"journal":{"name":"Advances in Life Science and Technology","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128471124","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}

Tomato ripening is highly dependent on ethylene action as a climacteric fruit, making this fruit highly perishable in a short period of time. Pre-storage treatments such as CaCl 2 and edible coatings are essential for preserving fruit quality after harvest and extending shelf life. The purpose of this study was to determine the effect of CaCl 2 and edible coatings on tomato postharvest quality and shelf life. The experiment was set up in the form of a Complete Randomized Design with three replications. The results revealed that both CaCl 2 and edible coatings had a highly significant (p˂0.01) effect on tomato shelf life and quality. Fruits treated with 6% CaCl 2 and coated with aloe Vera gel and beeswax significantly reduced physiological weight loss (PLW), percentage decay, TSS, pH of tomato juice, and ascorbic acid loss during storage, and increased the shelf life of the fruits by 15 days when compared to the control. The combination of treatments (6 percent CaCl 2 with AG and BW coating) resulted in the highest fruit marketability, firmness, and ascorbic acid levels over the storage period. According to the findings of the study, the combination of treatments 6 percent CaCl 2 with aloe Vera gel or bees wax can be recommended for Shanty tomato in terms of shelf life and quality.

The phenotype of an individual is determined by both the genotype and the environment, these two effects are not always additive which indicates that genotype x environment interactions (GEI) are present. The presence of genotype x environment interaction contributes to the unreliability 'of crop yield over a wide range of environments. The occurrence of large genotype x environment interaction makes the selection of superior genotypes difficult and inhibits progress from selection. It prevents the full understanding of genetic control of variability. In the absence of GEI, the superior genotype in one environment may be regarded as the superior genotype in all, whereas the presence of the GEI confirms particular genotypes being superior in particular environments. Therefore, it is important to understand the nature of genotype x environment interaction to make testing and selection of genotypes more efficient. A variety of statistical procedures are available to analyze the results of multi-environment trials. Additive Main Effects and Multiplicative Interaction (AMMI) model which combines the conventional analyses of variance for additive main effects with the principal components analysis (PCA) for the non-additive residuals and Genotypic Main effect plus genotype by environment interaction (GGE) biplot are two popular graphical analysis systems for multi-environment trials.
