Berries: Cultivation and environmental factors effects on the phenolic compounds content

Berries are rich in bioactive compounds, such as vitamins, fiber, macro and microelements and have high content of polyphenols, plant secondary metabolites. The consumption of a diet rich in polyphenols has in epidemiological studies been associated with a lower incidence of degenerative diseases including cancer, cardiovascular and other diseases. The preventive effects are often attributed, in part, to phenolic...

Impacts of climate change on global coffee production industry: Review

Next to petroleum oil, coffee is the most internationally transacted commodity in the world; consumers from all around purchase and enjoy coffee in their daily activities. Climate change has emerged in recent years as one of the most critical topics at almost all actors. The impact of climate variation in all producing countries is predicted to be negative, even though within each country, it would vary a lot....

Role of phytohormones (indol acetic acid, jasmonic acid, salcylic acid, and ethylene) in nematode-plant interactions

Plant parasitic nematodes are among the most destructive major pest of crop plants. Root knot nematode species and cyst nematodes are well studied species of nematode with various ranges of host. The common means of control for these pests mostly rely usually on use of chemicals like nematicides, which are environmentally unfriend and costly especially in large scale agricultural production systems. However, recent...

Superiority of Malawian orange local maize variety in nutrients, cookability and storability

The objectives of this study were to evaluate the potential of an orange Malawian local maize variety MW5021 by comparing with a hybrid variety DKC-9089 for nutritional quality and processing properties such as proximate and mineral composition as well as pasting and thermal properties of the flour, and resistance against Prostephanus truncatus infestation during storage of the grain. Maize plants sampled for the...

Conservation agriculture, conservation farming and conventional tillage adoption, efficiency and economic benefits in semi-arid Zimbabwe

Conservation practices can be of great importance in semi-arid regions for obtaining high crop yields and income, but adoption of the conservation practices, economic efficiencies and benefits remain unknown by most smallholders. The paper presents an overview of the adoption of conservation agriculture (CA), conservation farming (CF) and conventional tillage (ConvT), their technical efficiency and economic benefits....

Influence of ascorbic acid on physiological deterioration of pieces of cassava raw pulp

Cassava (Manihot esculenta, Crantz) is originally from South America and possibly Brazil, grown to more than 500 years. Its roots can be exploited in various ways for human consumption. With the focus on post-harvest cassava, this experiment was developed with the objective of evaluating the use of ascorbic acid (AA), on physiological deterioration in cassava roots minimally processed during the storage period of six...

Response of bread wheat (Triticum aestivum L.) varieties to N and P fertilizer rates in Ofla district, Southern Tigray, Ethiopia

A field experiment was conducted during the 2006 cropping season in Ofla district in southern Tigray to assess the response of bread wheat (Triticum aestivum L.) varieties to nitrogen and phosphorus fertilizer rates. Factorial combinations of two wheat varieties (HAR1685 and Shehan), four N rates (0, 23, 46 and 69 kg N/ha), and four P rates (0, 10, 20 and 30 kg P/ha) were laid out in split plot design (varieties in the...

Characterization of soybean population with sulfonylurea herbicides tolerant alleles

With the introduction of commercial soybean genotypes with Als1 and Als2 alleles that confer tolerance to different active ingredients of sulfonylurea group, this work aims to test soybean populations for the presence/absence of Als1 and Als2 alleles and evaluate the agronomic impact of these alleles addition. These trials were conducted in experimental stations of DuPont Pioneer at Sorriso, Mato Grosso state and...

Assessment of yield loss in Rosemary (Rosmarinus officinalis L.) and Sage (Salvia officinalis L.) plants caused by Fusarium oxysporum

Rosmarinus officinalis and Salvia officinalis wilt caused by Fusarium oxysporum could lead to yield losses, under various conditions. This study was therefore focused on determination of yield loss caused by F. oxysporum on R. officinalis and S. officinalis plants. A greenhouse experiment was conducted at Wondo Genet College of Forestry and Natural Resources (WGCFNR), Ethiopia, from 2015 to 2016. Mixed soil of animal...

Classification of selected white tropical maize inbred lines into heterotic groups using yield combining ability effects

A line x tester mating design involving sixteen white maize inbred lines as females and two testers as males generated thirty-two single crosses. These hybrids plus three checks were evaluated using a 5 x 7 alpha lattice design replicated twice at the University of Ghana, WACCI research farm during 2015/16 offseason using drip irrigation. The objective of the study was to: assign the tropical inbred lines into heterotic...
