Selection of drought-tolerant tef (<em>Eragrostis tef</em>) genotypes using drought tolerance indices
Item type: Journal Article • Journal: South African Journal of Plant and SoilDrought stress is one of the major abiotic constraints affecting production and productivity of tef (Eragrostis tef). Genetic resources and selection methodologies are among the prerequisites to improve the efficiency of breeding for drought tolerance. The objectives of this study... -
Web-based teaching, learning and research using accessible real-time data obtained from field-based agrometeorological measurement systems<xref rid="FN0001"/>
Item type: Journal Article • Journal: South African Journal of Plant and SoilTo enhance teaching and learning in agrometeorology and allied disciplines, a Web-based data and information system was developed. The system uses field-based agrometeorologcial measurements, from automatic weather, radiation and temperature stations, to collect and display near real-time and previous data... -
A Q-EXTENSION OF A PRODUCT FORMULA OF WATSON
Item type: Journal Article • Journal: Quaestiones MathematicaeA q-analogue of a formula of G.N. Watson that gives the product of two non-terminating Gaussian hypergeometric functions as a sum of two F 4 Appell series is obtained. of the many possible q-extensions of the 2 F1 function,... -
Models for estimation of carbon sequestered by <em>Cupressus lusitanica</em> plantation stands at Wondo Genet, Ethiopia
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest ScienceThis study compared models for estimating carbon sequestered aboveground in Cupressus lusitanica plantation stands at Wondo Genet College of Forestry and Natural Resources, Ethiopia. Relationships of carbon storage with tree component and stand age were also investigated. Thirty trees of... -
Performance of simple irrigation scheduling calendars based on average weather data for annual ryegrass
Item type: Journal Article • Journal: African Journal of Range & Forage SciencePoor irrigation management in pastures can lead to yield and quality reduction as well as loss of income through extra pumping and leaching of nitrate fertiliser. A number of irrigation scheduling techniques of varying levels of sophistication have been developed... -
Forage yield and quality response of annual ryegrass (<em>Lolium multiflorum</em>) to different water and nitrogen levels
Item type: Journal Article • Journal: African Journal of Range & Forage ScienceWater and nitrogen shortages in annual ryegrass (Lolium multiflorum) production can be improved by using proper irrigation and nitrogen scheduling methods. The aim of this research was to analyse the effect of water and nitrogen application on dry matter production... -
Silvopastoral system based on <em>Ficus thonningii</em>: an adaptation to climate change in northern Ethiopia
Item type: Journal Article • Journal: African Journal of Range & Forage ScienceThis study in northern Ethiopia investigated local people's perception of climate change and the role of indigenous silvopastoralism in adaptation to that change. Two hundred and forty respondents participated in a questionnaire survey and group discussions. Local communities perceive climate... -
Effect of integrated soil bunds on key soil properties and soil carbon stock in semi-arid areas of northern Ethiopia
Item type: Journal Article • Journal: South African Journal of Plant and SoilLand degradation is a serious global problem. To reclaim degraded land, many soil bunds have been implemented. However, their effectiveness has not been studied in all regions of Ethiopia. The objective of this study was to investigate the effect of...
