Development and technical validation of spray kit for coffee harvester

Spraying a coffee plantation simultaneously with harvesting ensures that the coffee plants are protected from pests and diseases, which are intensified during this period. In addition to economical operation, the pulverizer adapted to all harvester models promotes greater uniformity in pulverized syrup dispensing since the spray tips are arranged evenly around the plant. Two experiments were carried out in the...

Pig compost for the formation of coffee seedlings in the substrate composition

Pigs can be used in the formation of coffee seedlings; it gradually provides essential nutrients for the development of plants, in addition to promoting the improvement of the substrate and water retention. It was decided, with this work, to evaluate the use of pig compost in the formation of coffee seedlings. The topics studied were: T1 - Witness (absence of organic compound); T2-30% concentration of cattle compost;...

Correlation of climatic elements with phases of the lace bug Vatiga illudens (Hemiptera: Tingidae) in two cassava cultivars (Manihot esculenta Crantz, Euphorbiaceae)

Cassava (Manihot esculenta Crantz) is subject to various disease problems and insect attacks. The aim of this study was to evaluate the correlations of climatic elements on the phases of the lacebug, Vatiga illudens in two cultivars of cassava. The study was carried out in a greenhouse using the ‘Sergipana’ and ‘Campina’ cultivars. Data were analyzed using the Pearson index for linear...

Comparison of cyanobacterial bio-fertilizer with urea on three crops and two soils of Ethiopia

Although chemical fertilizers have long been used to meet the high demand of nitrogen (N), the most common limiting nutrient to plant growth, the frequent use of this fertilizer gradually deteriorates soil fertility in addition to its high cost, lower supply and agronomic use efficiency in Ethiopia. Nevertheless, N-fixing cyanobacterial biofertilizers are eco-friendly, and currently considered important to support the...

Genetic variation and heritability of kernel physical quality traits and their association with selected agronomic traits in groundnut (Arachis hypogeae) genotypes from Uganda

Breeding for improvement of physical kernel traits has a direct implication on acceptance of groundnut varieties. However, the genetic parameters associated with these traits are not well documented. Ten groundnut lines were evaluated in a Randomized Complete Block Design experiment with three replicates in 2015. Data were collected on yield parameters and pod and kernel physical traits. Mean values were used to...

Evaluation of the effectiveness of different trap designs for the monitoring of Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae) in blackberry crop

Spotted Wing Drosophila (SWD), Drosophila suzukii is one of the most important pests in berry crops around the world. In this study, different models of traps were evaluated for monitoring adult SWD. The study was conducted in a commercial blackberry orchard of the cultivar Chester, in the municipality of Vacaria, RS, Brazil in May 2016. The treatments consisted of three trap designs, namely the European model...
