Use of vegetable oils in the control of Colletotrichum sp. in banana fruits

Anthracnose is a disease caused by the fungus of the genus Colletotrichum. It is considered an important post-harvest disease in fruits of banana (Musa sp.) which depreciates the commercial value of the fruit. The use of vegetable oils to control fungal growth and disease progression in plants is an important alternative to minimize the deleterious effects of toxic chemicals. Studies were carried out to evaluate the...

Maize-lupine intercrop response to applied nitrogen and phosphorus in North-Western Ethiopia

Maize (Zea mays) is a major staple crop in North-Western Ethiopia. Narrow leaf lupine (Lupinus angustifolius) grain is a commercial concentrates for livestock feed. Maize-lupine intercropping is a sustainable and emerging crop production approach for the resource poor smallholder farmers of North-Western Ethiopia; however, there is no recommended fertilizer rate for the intercrop. Therefore, field experiment was...

Growth of parica seedlings (Schizolobium amazonicum Huber ex Ducke) cultivated in different organic substrates

The forest plantations depends on appropriate initial seedling establishment, which occurs when primary factors (water, light, CO2 and nutrients) are within appropriate ranges. The purpose this study was to evaluate the growth of young parica plants (Schizolobium amazonicum Huber ex Ducke) grown in different organic substrates (chicken manure, goat manure and organic matter) in proportions of 5, 10, 15 and 20% in yellow...

Virulence and characterization of isolates of potato bacterial wilt caused by Ralstonia solanacearum (Smith) in Rwanda

Bacterial wilt (Ralstonia solanacearum) is one of the major potato diseases in Rwanda. An in vitro study was carried out to identify and characterize the pathogen isolated from three potato cultivars (Kinigi, Kirundo and Gikungu) in Rwanda. This was achieved by cultural and morphological tests on triphenyl tetrazolium chloride (TTC) and casamino peptone glucose (CPG) agar as well as biochemical tests through Gram...

An assessment of adaptation options enhancing smallholder farmers’ resilience to climate variability and change: Case of Mbengwi Central Sub-Division, North-West Region of Cameroon

Farmers’ implementation of suitable adaptation measures in the face of climate variability and change (CVC) depends first and foremost on their ability to perceive CVC. This paper analyzes the adaptation measures implemented by smallholder farmers (SHFs) in Mbengwi Central Sub-Division, North-West Region of Cameroon in the face of CVC as well as the determinants of smallholder farmers’ choice of adaptation...

Comparison of bioslurry to common nitrogen sources on potato (Solanum tuberosum L.) yield and yield components in andisols and oxisols of Northern Rwanda

This study evaluated the effect of bioslurry from on-farm biogas production units and other sources of nitrogen fertilizer on Irish potato yield and yield components in northern Rwanda. To achieve this, an on-farm experiment was undertaken in the Andisols of Musanze District and the Oxisols of Gicumbi District in 2012. Three farms were selected to host the study in each District. Six treatments were randomly tested in...

Biomass accumulation and potassium concentrations in tissue of Teff (Eragrostis tef Zucc. Trotter) at three growth stages in Vertisols and Nitisols of the Central Highlands of Ethiopia

Understanding the physiology and time-course of above ground biomass (AGBM) and potassium (K) accumulation pattern in plants and removal from soil is essential to simultaneously increase crop yield and synchronize K demand and K supply, thereby predict crop yield. It is also an essential criterion for optimizing fertilizer practices, and may help to enhance soil and crop quality. A pot experiment was conducted using...

Isotopic signature of the relation between environment and the quality of spatial coffee

The intrinsic quality of the Bourbon cultivar is well known for a high level of sweetness, intense aroma and pleasant acidity. With the evident relationship between product quality and the environment in mind, the need arises for scientific studies to provide a foundation for discrimination of product origin. Given this context, the aim of this study was to evaluate the use of stable isotopes in discrimination of...

Osmotic stress in Chenopodium quinoa Willd.: Variations in osmoprotectants at different phenological stages

Chenopodium quinoa Willd. is an edible crop plant adapted to the climatic conditions of the South American Andes, where it thrives under extreme environmental conditions such as saline soils, drought, high UV radiation and broad temperature fluctuations. The prolonged exposure of this crop to high salinity and low relative humidity has promoted the development of efficient mechanisms to retain water within the...

Different dry matters content used for the conservation of annual ryegrass (Lolium multiflorum Lam.) in anaerobic environment

Annual ryegrass (Lolium multiflorum Lam.) is widely used for feeding ruminants, and the conservation of this material as haylage can be an alternative to farms. The aim of this work is to study the nutritional and microbiological value of annual ryegrass (L. multiflorum Lam.) pre-dried and stored with different dry matter contents (250, 350, 450, 550, 650 and 750 g kg-1) in anaerobic environment. The experimental design...
