Control strategies and breeding efforts in sorghum for resistance to storage weevils

Sorghum (Sorghum bicolor L. Moench) is one of the main staple cereal crops grown worldwide. It is used for food, feed, fodder and bio-ethanol. Biotic and abiotic challenges are the major constraints of the crop. Among the biotic constraints, weevil attack is the most devastating causing yield reduction ranging between 15 and 77%. This paper highlights control strategies and progresses of breeding sorghum towards...

Wheat cultivars agronomic characteristics and technological quality of flour depending on the row spacing

Proper handling of the wheat crop is crucial to obtain the full expression of the genotype potential. Among the various management techniques, the spatial distribution of plants and the disposal of the same plant in agriculture deserve attention. It is known that the distribution may alter the productivity; however, it is uncertain, the technological changes it might entails. With this in view, the aim of this study was...

Use of alternative waste wood substrates in the production of seedlings zinnia

Ornamental plants require a substrate that ensures the germination and healthy growth and vigor of the seedlings. Thus, this study aimed at studying the most suitable substrate for the production of zinnia seedlings from waste wood. The substrates evaluated in greenhouse were: Plantmax®; Sawdust (SM); SM + clay soil + sand (1: 2: 1); SM + clay soil + sand (2: 2: 1); SM + clay soil + sand (2: 1: 1); SM + clay soil...

Enzyme activities and gene expression in dry maize seeds and seeds submitted to low germination temperature

The study was conducted on dry maize seed and seed subjected to sub optimal germination temperature. Four lines of maize seeds were used, two were classified as susceptible to low temperature (44 and 54) and two tolerant to low temperature (64 and 91°C). Water content and germination tests were performed at different temperatures (10 and 25°C) to evaluate the physical and physiological quality of maize seeds....

Agronomic characteristics of sorghum in an agroforestry system with Eucalyptus in the semiarid region of minas gerais

The evaluation of agronomic characteristics of crops is important because they may be influenced by the height, density and spatial arrangements of eucalyptus in an agroforestry system. These silvicultural characteristics may interfere with height and   productivity of crops between the rows of the tree component due to shading, competition for water and nutrients. The objective of this study was to evaluate...

Geographic patterns of phenotypic diversity in sorghum (Sorghum bicolor (L.) Moench) landraces from North Eastern Ethiopia

Understanding the pattern of genetic variability is an important component of germplasm collection and conservation as well as the crop’s improvement process including the selection of parents for making new genetic recombination. Nine hundred seventy four sorghum landraces from North Eastern (NE) Ethiopia were evaluated for agro-morphologic characters to assess geographic patterns of phenotypic diversity and to...

Estimate of genetic parameters in bioactive and micronutrients compounds of maize

Maize (Zea mays L.) has a range of uses, from animal to human feed and can be consumed in nature, or as feedstock material in the preparation of starches, flours, canjicas, breads, beverages and porridges. This study aimed to determine the linear associations, estimates of genetic parameters and heterosis of bioactive and micronutrients compounds in maize. The experimental design was randomized blocks, the treatments...

The beverage quality of Conilon coffee that is kept in the field after harvesting: Quantifying daily losses

In search to maintain the coffee quality, the period of time for which the coffee is kept in the plantation after harvest (waiting transportation for the processing site) is one of the several factors that deserves scientific attention. This experiment aimed to identify and quantify losses of beverage quality suffered by Conilon coffee due to the time being kept in the field after harvesting, as an attempt to determine...

Phenotypic traits detect genetic variability in Okra (Abelmoschus esculentus. L. Moench)

There is low production of okra in Ghana due to lack of improved varieties and biotic constraints. This study was conducted to characterize okra genotypes to predict genetic variation in the crop. Field trial was conducted to determine genetic variability in 21 okra genotypes. The experiment was based on the randomized complete block design (RCBD) involving planting distance of 0.6 × 0.6 m. Thirty-one quantitative...

The use of tannery sludge vermicomposting in corn crop irrigated with sewage treated wastewater

The countless generation of waste (solid or liquid) by agro-industrial activities, has stimulated the development of researches aimed not only at the processing of these materials but also the possibility to take advantage of them in the agricultural environment. Therefore, this study aimed to evaluate the production of maize plants (Zea mays cultivar LG 6036) grown in pots containing Oxisol in addition to tannery...

Assessing the performance of innovation platforms in crop-livestock agro-ecosystems in the Volta basin

To enhance integrated rainwater management in crop-livestock systems in the Volta basin of Burkina Faso, innovation platforms (IP) comprising of multiple stakeholders were established in the districts of Koubri and Ouahigouya. Quarterly IP meetings were organized to collectively identify and prioritize constraints and opportunities, and to design and implement strategies to address them. IP represents an example of...
