Abstract: In Ethiopia field pea is produced in various regions and is widely grown in north, south, west and central parts of the country including, pocket areas in highland and mid highlands with altitude ranging from 1800-3000 m.a.s.l. Field pea can be grown on a wide range of soil types, from light sandy to heavy clay. Fertilizer responses of crops vary with the crop varieties used and climatic conditions of the production. Matching fertilizer application rates to crop needs is an essential component of optimizing crop production. The experiment was conducted at two locations in Bale, south eastern Ethiopia (Sinana on farm and Agarfa) to study effects of different levels of blended NPS levels on field pea performance for two consecutive years (2021-2022/23). The treatments were six rates of blended NPS fertilizer (0, 25, 50, and 75,100, and 125 NPS kg ha-1) laid out in randomized complete block design (RCBD) with three replications. Field pea variety Harena and Weyib were used for the experiment. The results of the study revealed that the analysis of variance among fertilizer rates showed no significant differences (P ≤ 0.05) on almost of field pea characters tested. Therefore, developing site specific fertilizer recommendations that consider existing soil nutrient supply and recommended fertilizer based on crop nutrient demand to achieve target yield is required.

Abstract: The field experiment was conducted during 2019/2020 cropping season to evaluate the response of different wheat varieties to different rates of NPSB fertilizer at Gimbi District, Western Ethiopia. The experiment was laid out in RCBD with a factorial arrangement with three replications and consisted of four rates of NPSB fertilizers (0, 50, 100, and 150 kg ha-1) and three bread wheat varieties (Liben, Digalu, and Local). The finding discovered that the effect of variety and NPSB fertilizer was significant for days to heading, grain per spikes, above-ground biomass, and straw yield. The varietal effect showed a highly significant effect (p<0.01) on grain yield. Grain yield significantly differed for the local wheat variety and the other two varieties (Liben and Digalu). However, grain yield did not significantly differ for Liben and Digalu wheat varieties. The lowest grain yield recorded for the local wheat variety was 1.99 ton ha-1and the highest grain yield was recorded for the two wheat varieties (Liben and Digalu) which were 3.5 and 3.66 ton ha-1, respectively. The highest grain yield was obtained when bread wheat varieties were fertilized by 150 and 100 kg blended fertilizer (4.18 and 3.87 tons respectively), but both rates are not significantly different from each other (p<0.01). The varietal effect showed a highly significant effect (p<0.01) on the harvest index (HI). The harvest index significantly differed between Local and the other two varieties (p<0.01). Based on the current finding, the grain yield was increased by 44.8 % when the two wheat varieties (Liben and Digalu) were used over the local wheat variety in that particular area. Therefore, further research has to be conducted to see the performance of these two wheat varieties in different locations of the district to come up with sound recommendations.

Abstract: Twenty-three food barley (HondiumVulgare L.) genotypes including with three standard check varieties were evaluated at three locations (Sinana, Robe area and Bekoji) for two years from 2020-2021. Data for grain yield and other important traits were generated and the Results of combined analysis and stability analysis showed that barley genotype coded as G8 and G18 exhibited the highest mean grain yield with high stability and good agronomic performance as well as good level of disease resistance across the testing environment. These two candidate genotypes were promoted to VVT (variety verification trial) along with two check varieties Adoshe and HB1966 to re-evaluated including farmers field using large plots for one year, in 2022. After critical evaluation of VVT by National Variety Releasing Committee (NVRC) and group of farmers, the first genotype, coded as G8, which has grain yield advantage 37.3% and 49.2% over standard checks Adoshe and HB1966 and later on given local name called “Gesse” was officially released for wider production for high potential barley growing areas of Ethiopia.

Abstract: Magnoliaceae Juss. are the most primitive taxa of Fructophyta D.L.Fu & H.Fu and have extremely important scientific values for the research of evolutionomy of fruit plants. Based on the evolutionary analysis of the complete chloroplast genomes of representative plants of Magnoliaceae in the NCBI (National Center for Biotechnology Information, USA) database, this paper firstly established the evolutionary systems of subgenera and sections of Magnolia L. and that of sections of Michelia L. and firstly proposed the evolutionary boundary of subgenera of Magnoliaceae Juss.. Magnoliaceae Juss. include 4 natural genera: Yulania Spach, Magnolia L., Michelia L. and Liriodendron L., which all have the same boundary: PHS (17bp) ≥ 0.9234 (intragenus) or PHS (17bp) ≤ 0.9232 (inter genera). The most primitive genus of Magnoliaceae Juss. is Yulania Spach not Magnolia L.. The genus Magnolia L. includes 7 natural subgenera and the evolutionary boundary is PHS (17bp) ≥ 0.938 (intrasubgenus) or PHS (17bp) ≤ 0.937 (inter subgenera). Magnolia subgen. Talauma (Juss.) Pierre includes 3 natural sections, Magnolia subgen. Manglietia (Blume) D.L.Fu includes 4 natural sections and Michelia L. includes 3 natural sections, which all have the same evolutionary boundary: PHS (17bp) ≥ 0.961 (intrasection) or PHS (17bp) ≤ 0.960 (inter sections). Moreover, 4 new subgeneric combinations, 1 new section and 3 new sectional combinations, 14 new specific names and 95 new specific combinations have been scientifically and validly published. This paper scientifically solves the confusion between the traditional classification system and the modern phylogenic system of Magnoliaceae, and lays a solid theoretical and practical foundation for the research of fruit plant evolution.
