Livestock herders’ perception on the causes and effects of Senna obtusifolia L. invasion in rangelands of Northern Ethiopia

Livestock herders’ perception on the invasion and effects of Senna obtusifolia L. were gotten from two locations (Kafta Humera and Tsegede) in Northern Ethiopia. From each location, three peasant associations were selected using key formants and group discussion. The invasion level of S. obtusifolia L. was higher near settlements and road side of continuously grazed lands of the study area. S. obtusifolia L....

Characterization of sweet potato accessions in Malawi using morphological markers and farmers’ indigenous knowledge system (IKS)

Characterization of landraces is central to any conservation measures devised for sweet potato in Malawi. Studies were therefore conducted using seven morphological descriptors and farmers’ indigenous knowledge systems (IKS) to investigate the phenotypical diversity of 286 landraces and 35 introductions of sweet potato from the north, south east and lower Shire. The accessions were planted in a check plot design...

Agronomic performance of wheat as a function of different spacing and sowing densities in two agricultural years

Optimization of the use of agricultural inputs and the efficient management of the wheat crop can increase the yield potential per unit area. Thus, the objective of this study was to evaluate the agronomic performance of a wheat cultivar in function of different spacing and sowing densities in two agricultural years. The experiment was performed during the 2010 and 2011 agricultural years.  The experimental design...

Potential of plant ethanolic extracts on Meloidogyne incognita control in tomato

Nematodes are obligatory parasites that compromise agricultural production worldwide. The use of alternative methods to replace the chemical pesticides in the control of this pest is increasingly growing, due to its pollution to the environment. In order to evaluate the biocidal effect of plant extracts, combinations of extracts of Neem (Azadirachta indica), croton (Croton campestris) and manioc (Manihot esculenta) were...

Nitrogen, phosphorus, and potassium fertilizer effects on cassava tuber yield in the coastal district of Dondo, Mozambique

Meeting an increasing demand for cassava (Manihot esculenta Crantz) by industrial and commercial food sectors requires basic agronomic information on fertilizer requirements and appropriate fertilizer recommendations for high tuber yield and quality. A no-till study involving twenty fertilizer treatments consisting of different combinations of nitrogen (N), phosphorus (P), and potassium (K) fertilizer rates was...
