Herbicidal effects of Datura stramonium (L.) leaf extracts on Amaranthus hybridus (L.) and Tagetes minuta (L.)
Evolution of weeds resistant to herbicides demands new solutions to cope with the problem since economic losses generated by weeds can be higher than those caused by insect pests. Bioactive compounds known as allelochemicals have the potential to act as natural herbicides in weed management in agro-ecosystems. Laboratory, pot and greenhouse experiments were carried out to investigate the herbicidal effects of Datura...

Implications of climate change and variability on food security in Kenya
This study assessed the impact of climate change and climate variability on food security in Kenya based on a sample size of 270 farmers randomly selected from semi-arid agro-ecological zones in Kenya. Both primary and secondary data were used in the present study. Data analysis was conducted using descriptive statistics and regression models. The results revealed that increase in temperature and reduction in rainfall...

Foliar application of bio-fertilizers influenced the endogenous concentrations of phytohormones and amino acids in leaves and roots of olive trees (Olea europaea L. cv. Chemlali)
The chemical composition of olive leaves and roots of Chemlali variety was evaluated regarding the contents of amino acids and endogenous phytohormones under foliar application of biofertilizers (F1: rich in nitrogen (N), phosphorus (P), potassium (K); F2: rich in calcium (Ca); F3: application of F1 and F2). The results of this study demonstrated significant effects of tested fertilizers on the concentrations of amino...

Multivariate analysis of phenotypic variability in Tef [Eragrostis tef (Zucc.) Trotter] genotypes from Ethiopia
Tef [Eragrostis tef (Zucc.) Trotter] is an important food crop in Ethiopia. The present research was conducted to characterize the phenotypic variability of 68 tef genotypes collected from Ethiopia. Where a Bi-replicated 7×10 alpha lattice design was used to evaluate the 70 tef genotypes at Holetta and Debre Zeit Research Centers during 2015. Based on the results of cluster analysis (CA), genotypes were grouped...

Identification of important morphological traits in Mozambican sorghum [Sorghum bicolor (L.) Moench] germplasm using multivariate analysis
Classification of sorghum [Sorghum bicolor (L) Moench] breeding material based on multiple crucial characters is important towards the possible formation of homogeneous groups of genotypes and groups that can be exploited in the identification of parents for use in a breeding program. The objective was to determine the morphological characters that distinguish desirable breeding material and group the genotypes of...
