Phenotypic variability and association of traits among yield and yield-related traits in Castor (Ricinus communis L.) accessions at Melkassa, Central Rift Valley of Ethiopia

A field experiment was conducted to study the genetic variability and association of characters among yield and yield-related traits in castor accessions at Melkassa, central rift valley of Ethiopia during the off season of the 2013/2014. A total of 48 castor accessions were evaluated by using randomized complete block design with three replications. Analysis of variance revealed that there was highly significant...

Efficacy of the association of cover crops with maize and direct sowing short-term effect on crops’ yields in maize-cotton cropping system in Western Burkina Faso

To improve the productivity and sustainability of cotton and cereals based system, direct sowing under mulch was tested for its efficacy on cotton and maize yields on the research station of Farako-Bâ, in Western Burkina Faso. The experimental design was a complete randomized blocks of Fisher with four replications. Conventional tillage by annual moldboard plowing (T7) was compared with direct sowing under...

Potassium forms of soils under enset farming systems and their relationships with some soil selected physico-chemical properties in Sidama zone, Southern Ethiopia

Soil potassium is classified as unavailable, readily available and slowly available (fixed) K forms. A research was conducted to determine the distribution of forms of K (water soluble K, exchangeable K, non-exchangeable K and total K) and their relation with some soil properties under enset farming systems of Sidama zone in South Ethiopia. The soils were collected from ‘Qola’ (dry, hot tropical climate and...
