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... Read more.

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 and... Read more.

Climate change effects are threats to the livelihood of Sub-Saharan smallholder farms. Farmers’ response and readiness to take adaptive measures depend on how they perceive (perception) and moreover understand and recognize the causes (awareness) of climate change. Most studies used interchangeably perception and awareness to climate change. Taking the example of soil nutrient management, this study demonstrated... Read more.

Chrysanthemum production stands out in ornamental plants market and several techniques can improve the production of this plant. Among them, is the use of beneficial microorganisms such as plant growth promoting rhizobacteria (PGPR); however, the use of PGPR has not been explored enough so far in chrysanthemum production, especially in field conditions. With regards to rhizobacteria, the group, Pseudomonas, can be... Read more.

Thirty six single cross hybrids with six commercial checks were evaluated for yield performance along with earliness, plant height and ear height. The mean performance for days to tasseling and days to silking were significantly different among the hybrids. Considering the yield, Kaberi 50 and Pioneer 3396 were found as the best and the second best check, respectively. None of the hybrids produced higher yield compared... Read more.

Globally, banana is the fourth most important fruit crop and is grown in more than 130 countries across the world. Traditional procedure to characterize banana plants by morphological descriptors has many limitations, and different communities refer to the same local cultivars by different names due to lack of clear clone identity resulting in unnecessary duplication with regard to cultivation, conservation and...

Many landraces and improved cultivars of sorghum (Sorghum bicolor) grown in Uganda have late maturity and are susceptible to several biotic and abiotic stresses. Introgression of the rhizomatous trait from perennial sorghum (Sorghum halepense) could improve stress tolerance. However, phenotypic characterization of exotic perennial sorghum germplasm under Ugandan environmental conditions is essential to select desirable... Read more.
