The treatments consists of five allowable soil moisture depletion level (ASMDL), i.e, 60% ASMDL, 80% ASMDL, 120% ASMDL, 140% ASMDL and control irrigation of 100% ASMDL. These five treatments were laid out in complete randomized block design with three replications. The irrigation water was applied based on allowable soil moisture depletion of (p=40%) considered for coffee Arabica. The over year analysis of variance showed that soil moisture depletion level significantly (P<0.05) affected coffee yield and water productivity. The average highest coffee yield of 2330 Kg/ha was obtained from the 120% ASMDL by applying 10145 m3/ha of water, while the FAO recommended treatment of 100% ASMDL produced the lowest yield of 1780 Kg/ha. The 60%, 80%, 100% and 140% treatments were not statistically significant from each another. Therefore, 120% ASMDL treatment gave above mean value of yield and water productivity and hence can be used as the allowable soil moisture depletion for coffee Arabica (coffee Arabica L.) in a coffee growing area of Gera.","PeriodicalId":117425,"journal":{"name":"International Journal of Research Studies in Agricultural Sciences","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128136474","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}

{"title":"Evaluation of Improved Common Bean (Phaseolus vulgaris L.) Varieties for Yield and Yield Components at West Hararghe, Eastern Ethiopia","authors":"Temesgen Begna, Zewdu Asrat","doi":"10.20431/2454-6224.0709002","DOIUrl":"https://doi.org/10.20431/2454-6224.0709002","url":null,"abstract":"Common bean is playing a crucial role across the world mainly in the warm and lowland areas of the country including Ethiopia. Understanding the level of drought tolerance of the varieties available in each country is of paramount importance for breeding common bean for drought adaptation. However, the production of common bean is mainly limited due to lack of high yielding potential varieties and frequent and recurrent drought. Hence, the study was aimed to evaluate and identify the superior performance and genetic potential of improved common bean varieties for yield and yield related traits against drought. A total of 10 recently released improved common bean varieties were evaluated using a randomized complete block design (RCBD) with three replications at Mieso during the main cropping season of 2018 and 2019. The information generated on the drought tolerance of the available varieties should help in the design of a breeding strategy that incorporates adaptation traits with commercial characteristics preferred by common bean farmers for varieties to be grown in diverse environments. The combined analyses of variance revealed the presence of tremendous genetic variation among improved common bean varieties for all the studied traits except plant height and stand count at harvest, which implies the availability of substantial genetic variation among varieties. Overall, SER-125, SER-19 and Nasir common bean varieties had better performance compared to the other varieties for yield and the yield related traits. The maximum grain yield was obtained from SER-125 (2620 kgha -1 ) followed SER-19 (2612 kgha -1 ) and Nasir (2583.33 kgha -1 ) common bean varieties and identified as the superior improved common bean varieties. Eventually, the effect of varieties on grain yield was significant and the best performing varieties of common bean would be recommended for the specific community and its vicinity even though further study should be carried out including a number of recently released varieties for improved common bean production in the target area and also to put the recommendation on strong basis. Therefore, based on the results of this adaptation experiment, SER-125, SER-19 and Nasir were recommended for production and adoption at Mieso and other similar environments.","PeriodicalId":117425,"journal":{"name":"International Journal of Research Studies in Agricultural Sciences","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131677892","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 the first season, the trial was conducted by using 4 nutrient management treatment (control, 100% poultry manure (PM), 100% NPK and 50% NPK + 50% PM) in 3 cropping system (sole maize, sole soybean and maize + soybean intercropping).  The following trial was conducted by using the first experimental plot. After harvest of the crops in the first experiment, the biomass was left and incorporated manually into the soil before planting the subsequent maize crop. The experiment comprised of 14 treatments, 12 based on the first experiment and two additional treatments for comparison (control and 100% NPK). The treatments were laid down in a randomized complete block design (RCBD) with three replications. The results showed that all fertilizer treatments increased growth, yield and yield components of the subsequent maize crop. However, incorporation of maize residue alone was ineffective in increasing yield of the subsequent maize crop. The combination of crop residue with residual PM enhanced soil pH, organic matter and nutrient availability in the soil. The combined application of soybean residue + 50% residual PM + 50% phosphorous and potassium (PK) fertilizer and soybean residue + 100% PK gave maize yield same level as 100% NPK. Therefore, it can be recommended that substitution of 50% inorganic fertilizer with residual PM and substitution of N fertilizer in soybean residue is recommended to increase yield of maize and improve soil chemical properties.
