Integrated management of Meloidogyne incognita in tomato (Solanum lycopersicum) through botanical and intercropping
Root-knot nematode, Meloidogyne incognita, is the major limiting factor in tomato production in many regions of the world, including Ethiopia. Hence, there is a need for development of root-knot nematode management methods that are cheap and environmentally friendly. A greenhouse experiment was conducted with an objective to evaluate the integrated effect of botanicals and intercropping against M. incognita on tomato....

Vertical versus horizontal expansion of food security crops in Sudan: A causality analysis of 1961-2017
This research used FAO statistical data to test the causality between production, area and yield for Sudan’s three major food crops; sorghum, wheat and millet. Results indicated a sizable gap in yield between Sudan and some selected top producing countries for the selected crops. Two-way causality was observed from production to area and vice versa for sorghum crops, accentuating horizontal expansion, while the...

Assessment of physicochemical properties of Besease wetland soils, Ghana
The shallow and erodible soils of low fertility uplands have led to farmers extending their cultivable areas to wetlands for optimal crop production since these systems have the potential for exploitation in the dry season. To ensure its sustainable use, the physicochemical and the hydrological characteristics of the valley bottom should be ascertained. Studies were conducted to assess the suitability of wetlands for...

New microchondrometer to measure hectoliter weight in small samples of wheat
The hectoliter weight or test weight is an important wheat quality parameter for international trade and is traditionally evaluated on devices with a volume of 250, 500, 1000 or 1100 ml. At the experimental level, especially in crop improvement and in greenhouse studies, the amount of grain is often insufficient to determine hectoliter weight. The present work aimed to evaluate the feasibility of using a new 15.30 ml...

Lime requirements for bean production on two contrasting soils of Lake Victoria Crescent agro-ecological zone
In East Africa, research has indicated that N, P and soil acidity are the major production constraints to common bean production. The optimum pH for bean production in tropical soils ranges from 5.8 to 6.5. But in Uganda, 23% of beans are grown in soils with pH below 5.0. Research conducted on common bean production is mainly about the major nutrients and information about lime requirements to address soil acidity in...

The response of pigs to diets containing varying levels of cocoa placenta meal (CPM) supplemented with an exogenous enzyme complex
A nineteen-week experiment was conducted to establish the effects of an enzyme supplementation on growth performance, economics of production, carcass components and blood profile of pigs fed diets containing different levels of cocoa placenta meal (CPM). Twenty-five Large White grower pigs with mean initial live weight of 15.4 kg were randomly allocated to five treatments: T1 (0% CPM), T2 (5% CPM), T3 (10% CPM), T4...

Initiation of callus from different genotypes of Sorghum bicolor L. Moench
The study aimed to examine three genotypes of sorghum for their response in tissue culture using Murashige and Skoog (MS) medium supplemented with auxins (2,4-dichlorophenoxy acetic acid (2,4-D), naphthalene acetic acid (NAA)) and cytokinins (Kinetin, 6-benzyle amino purine (BAP)) at different concentrations. The cultures were initiated from different explants (seed, embryo and hypocotyl). The response of explants...
