| 7 | Evaluation of Germplasm of Pearl Millet(Penissetum glaucum L.)for Agronomic,Physiological and Biochemical Traits under Semi-arid Conditions of Hamelmalo显示文摘A field experiment was conducted at the experimental farm of Hamelmalo Agricultural College during summer 2017,to evaluate the agronomic,physiological,and biochemical performance of the collected Eritrean germplasm of pearl millet.A total of 16 accessions were tested,out of which 2 were improved varieties included as a check.The experiment was laid out in 4 x 4 Simple Lattice Design with Randomized Block using 4 replications with a gross plot size of 3.0 m x 1.2 m,row to row spacing of 75 cm and plant to plant spacing of 30 cm.The data collected were Agronomic parameters(growth,development,yield,and yield contributing characters);Physiological parameters(Relative water content and Water Use Efficiency);and Biochemical parameters(crude fat,crude fiber,protein content,TSS,and ash content).The data were analyzed using GENSTAT software and correlation analysis was worked to see the positive and negative contribution of agronomic,physiological,and biochemical attributes.The results of the study showed that Bariyay908 and Kona being statistically at par with Bariyay 910,Hagaz,Zibedi,Shleti,Delkata,Tokroray,and Kunama produced significantly higher grain yield.However,among these Baryay908 because of its superior agronomic characteristics,lower incidence of downy mildew,relatively higher water use efficiency and higher crude protein content were found to be comparatively superior to the check improved varieties Kona and Hagaz.Grain yield has shown a positive and significant correlation with harvest index,number of seeds per panicle,panicle length,leaf area and water use efficiency.These promising accessions need to be further tested for future breeding programs to develop varieties higher in productivity and resistant to downy mildew under semi-arid conditions of Eritrea. | Habteslase Teklu Tesfagiorgis Woldeamlak Araia N.N.Angiras | 2021 | Journal of Botanical Research2021，3，3： | 0 |
| 8 | Evaluation of Sorghum (Sorghum bicolor) Landraces for Drought Tolerance Using Morphological and Yield Characters under Rainfed Conditions of Sub Region Hagaz, Eritrea显示文摘Sorghum is an important food crop in Eritrea where it is widely grown in the mid and low lands,of semi-arid regions.Eritrea being the center of origin of sorghum,a large variability exist in its landraces being grown by the farmers since generations.In order to improve the productivity of sorghum under moisture stress conditions,it is imperative to evaluate these landraces for drought tolerant characteristics and their use for further crop improvement programmes.Therefore,a field study was conducted in a randomized complete block design with three replications to estimate the extent of genetic variability of 20 sorghum genotypes for moisture stress tolerance using various morphological,phenological,yield and yield related parameters under rainfed conditions at Hagaz Research Station.Significant difference was observed for almost all the characters in the individual analysis of variance suggesting that these sorghum accessions were highly variable.Accessions EG 537,EG 1257,EG 849,EG 791,EG 783 and EG 813 showed promising results for post flowering drought tolerance,grain yield and stay green traits.Higher PCV and GCV were also obtained in parameters like plant height,leaf area,biomass,peduncle exertion,panicle length,and grain yield and panicle weight.The genotypes also exhibited varying degrees of heritability estimates.Characters such as plant height,panicle length,days to flowering and maturity showed higher heritability.Cluster analysis revealed that sorghum landraces were grouped on the basis of their morphological traits and geographical sites.77.3%of the total variation of sorghum landraces was contributed by the first four principal components analysis having Eigen value>1.Overall,the current study confirmed that EG 537,EG 849,EG 1257,EG 791,and EG 813 are drought tolerant sorghum landraces during post flowering stage. | Mebrahtom Tesfazghi Tesfamichael Abraha Woldeamlak Araia Nitya Nand Angiras | 2022 | Journal of Botanical Research2022，4，4： | 0 |
| 9 | Soil and water conservation effects on soil properties in the Middle Silluh Valley,northern Ethiopia显示文摘Community-based Soil and Water Conservation(SWC)practices have been adopted in the Tigray region since 1991 for restoration of the degraded landscape.The effects of those conservation measures on physico-chemical properties of soil were limitedly studied.Thus,this study evaluated the effects of SWC on selected soil properties in the Middle Silluh Valley,Tigray region,Northern Ethiopia.The study considered conserved landscapes(terraced hillside,terraced farmland and exclosure area)and non-conserved landscapes(non-terraced hillside,non-terraced farmland and open grazing land)for comparison using a one-way analysis of variance(ANOVA).A total of 24 samples were collected from each landscape at a depth of 10–30 cm.The results indicated that mean bulk density(BD)was low on terraced hillside,non-terraced hillside and exclosure area.Sand and clay content were significantly different at P<0.05 for the six landscape categories.Higher mean organic matter was observed in the conserved landscape,as compared with the corresponding non-conserved landscape.Pearson's correlation between Soil Organic Matter(SOM)and clay content,SOM and Total Nitrogen(TN)showed strong positive relationships.Overall,the results show that SWC had significantly positive effects on soil's physical and chemical properties in the study area. | Solomon Hishe James Lyimo Woldeamlak Bewket | 2017 | International Soil and Water Conservation Research2017，5，3： | 0 |
| 10 | Effect of Dates and Methods of Sowing with and without Hydropriming on Growth,Phenology and Yield of Sorghum under Semi Arid Conditions of Eritrea显示文摘A study was carried out at the research farm of Hamelmalo Agricultural College during summer 2015 to study the effect of dates and methods of sowing with and without hydro-priming on growth,development and yield of sorghum.The experiment consisted of 2 factors-three dates of sowing viz.D0(Sowing before the onset of first summer rain,June 30),D1(Sowing with the onset of first summer rains,July 7)and D2(Sowing after the onset of summer rains,July 14)and three methods of sowing viz.SP(Direct sowing with hydro seed priming),TR(Transplanting)and DS(Direct sowing without hydro seed priming).The experiment was conducted in split plot design with 4 replications by keeping dates of sowing in the main plots and methods of sowing in the sub plots.The data on growth parameters,crop phenology,yield components and yield were recorded.The data were analysed using GENSTAT software and inferences were drawn by using LSD at 5%level of significance.Sowing methods significantly affected leaf area and leaf area index but sowing dates and their interaction with sowing methods did not show significant difference.Stand count,plant height,phenological parameters,thousand grain weight,grain and biomass yield were significantly affected by the sowing dates and methods but no significant difference in their interaction on all the parameters except in stand count and phenological parameters.Sowing before the onset of first summer rains(D0)resulted in significantly highest grain yield.Among the sowing methods,transplanting resulted in significantly higher grain yield seconded by direct sowing with hydro seed priming.Transplanting is less profitable and practicable as it is more laborious and difficult to apply in larger areas. | Berhane Teklesenbet Negassi Woldeamlak Araia Nitya Nand Angiras | 2021 | Journal of Botanical Research2021，3，2： | 0 |
