Growth and physiological responses of coffee (Coffea arabica L.) seedlings irrigated with diluted deep sea water

Concentrations of 5, 10, 20, and 40% deep sea water (DSW) were tested, with irrigation water serving as the 0% control (tap water) on coffee (Coffea arabica L.) seedlings. The results showed that the growth parameters were affected significantly (α < 0.05) by the irrigation of 20 and 40% deep sea water. There were significant differences (α < 0.05) among treatments in stomata density/mm2, stomata...

Sole and combined effect of three botanicals against cowpea seed bruchid, Callosobruchus maculatus Fabricius

The bioactivity of three botanical powders in sole and combination against Callosobruchus maculatus (Fab.) was investigated at 29±3°C and relative humidity (R.H.) OF 65+5% in the laboratory. The appropriate mixing ratio of Cymbopogon citratus (C), Alstonia boonei (A) and Hyptis suaveolens  involved seven  combinations viz., C:A, C:H, A:H, C:A:H, H2:C:A, A:C2:H, H:C:A2 in simple ratios 1:1, 1:1, 1:1,...

Land use effects on soil erodibility and hydraulic conductivity in Akure, Nigeria

This research was carried out to investigate the effects of three land use categories (grazed, cropped and forest land) on soil erodibility and hydraulic conductivity. Hydraulic conductivity was determined by a steady‐state flow using a mini‐disk infiltrometer while soil erodibility was determined following the Wischmeier and Smith equation. A suction rate of 2 cm s-1 was chosen for field infiltration measurement...

Evaluation of the effect of genotype, environment and genotype X environment interaction on white common bean varieties using additive main effect and multiplicative interaction (AMMI) analysis in the mid-altitude of Bale zone, Southeastern Ethiopia

Twelve white common bean genotypes were evaluated along two checks at three diverse locations in the mid-altitude of Bale zone, southeastern Ethiopia for two consecutive years 2014 and 2015 in order to determine their stability. The genotype by environment interaction (GEI) has an influence on the selection and recommendation of cultivars. The objective of this work was to see the effect of GEI and evaluate the...
