Impact of shade on morpho-physiological characteristics of coffee plants, their pests and diseases: A review

Traditionally, coffee plant has been considered as a shade demanding species and intolerant of direct sunlight, although it performs well without shade. Still controversy result and recommendation have been reported among investigators in the optimal shading level for coffee growth. This controversy will probably continue endlessly until the effects of shade up on the performance of morphology and physiology of the...

Agronomic effectiveness of water hyacinth-based composts

Because water hyacinth-based compost contains substantial amounts of nitrogen (N), phosphorus (P) and potassium (K) its application can boost crop production. We evaluated the agronomic performance of water hyacinth - based composts using field experiments and five treatments which were; water hyacinth compost made using cattle manure (WH+CM), poultry manure (WH+PM), molasses (WH+MO), water hyacinth alone (WH alone) and...

Bioactivity and phenolic composition of extracts of noni (Morinda citrifolia L., Rubiaceae) in tomato moth (Tuta absoluta Meyrick, 1917) (Lepidoptera: Gelechiidae)

We evaluated the bioactivity of Morinda citrifolia L., Rubiaceae on Tuta absoluta (Lepidoptera: Gelechiidae) and quantified the phenolic components. Ethanolic extracts of leaves and fruits were used in five concentrations (0.01, 0.02, 0.03, 0.04 and 0.05 mg / L). The leaves of the plants were immersed in the solution (10 s) and placed in contact with five caterpillars of the same instar in Petri dishes. The caterpillars...

Determination of tomato drying conditions with solar energy family type shelf dryer

In this study, working parameters of the system consisting of air heaters and dryer with solar energy of 0.20 m2 with a space of 0.72 m2 and 10 pieces in the cabin were investigated experimentally. Average atmospheric air temperature and relative humidity values during the dry daylight hours were measured at 49°C and 35%, respectively. As a result of the examination of the test results, the atmospheric air...

Effects of seed tuber size on growth and yield performance of potato (Solanum tuberosum L.) varieties under field conditions

Potato (Solanum tuberosum L.) is an important food and cash crop in Ethiopia; serving, as a food security crop due to its nutrition content, wider adaptability and early maturing behavior. However, the yield of the crop is constrained by a number of factors. Among which unspecified seed tuber size and limited availability and distribution of improved varieties are among the important limiting factors. A field experiment...
