New type of trap for monitoring banana weevil population

The objective of this study was to test the efficiency of a new model of trap by comparing it with the most recommended and used traps by producers to monitor Cosmopolites sordidus in areas of production of plantains. Three types of vegetable traps were tested: cheese, modified roof tile and a new trap called wedge. The experiment was carried out in five areas of production, measuring one hectare each, in which 20 traps...

Productive and physiological performance of lettuce cultivars at different planting densities in the Brazilian Semi-arid region

In regions of high temperature, production and quality in the lettuce is reduced. This requires finding of cultivars that are more adapted to such conditions and adjust the planting density for each cultivar. Consequently, the aim of this study was to evaluate the productive and physiological performance of lettuce cultivars at different planting densities under semi-arid conditions. The experiment was carried out at...

Correlation and path coefficient analysis of top-cross and three-way cross hybrid maize populations

Grain yield is a complex quantitative trait that depends on a number of other traits for selection.  This study was carried out to reveal the pattern of association with and contribution of traits to grain yield in two maize populations evaluated in three agro-ecological zones of South-Western Nigeria during the 2014 cropping season. The experiment consisted of 10 top-cross and 10 three-way cross maize hybrids,...

Micronutrients application on cultivation of sugarcane billets

The production of sugarcane is constantly growing in Brazil, and by the 2016/2017 season, it is estimated to have reached 691 million tons. However, productivity has not shown significant increase, this is due largely to inadequate nutritional supplementation of sugarcane plantations, especially the micronutrients. The aim of this study was to evaluate the effect of micronutrients application on the billets and quality...

Contributive effect of growth regulator Trinexapac-Ethyl to oats yield in Brazil

Studies on efficient use of the plant growth regulator can make this technology possible for leveraging oat yield in Brazil. This study aims to define the optimal dose growth regulator in oat, which allows plant lodging at most 5%. Establishing equations describe the yield indicators behavior and by using the optimal growth regulator dose for lodging, simulate the expression of these indicators regardless of reduced,...

Phytosociological survey of arboreous species in conserved and desertified areas in the semi-arid region of Paraíba, Brazil

The objective of this study is to perform a phytosociological survey of the arboreous composition in conserved and desertified areas of the semiarid region of Paraiba State. Twenty-two conserved areas (CA) with native vegetation (Caatinga) where there has been no clear cut logging since 1984, and Twenty-two desertified areas (DA) having a difficult re-establishment of vegetal coverage over the past 10 years were...

Assessing rural farmers’ perceptions and vulnerability to climate change in uMzinyathi District of Kwazulu-Natal, South Africa

There is little awareness among rural farming communities on their vulnerability to climate change. This paper examined the vulnerabilities of the rural small scale farming communities in the uMzinyathi District of KwaZulu-Natal, South Africa to climate change. A survey among 200 households who were randomly chosen but who had lived in the community for over twenty years was conducted. Focus group discussions and key...

Upland rice growth and yield response to weed management practices under rainfed conditions in Morogoro, Tanzania

Field experiments were conducted in two seasons at the farm of Sokoine University of Agriculture in Morogoro, Tanzania (6.85°S; 37.64°E and 568 m.a.s.l.) during the short rain (November 2014 to January 2015) and the long rain (March to June 2015). The experiment was a split plot in randomized complete block design (RCBD) with 4 replicates. Weed management practices (herbicides, hoe weeding (3x) and weedy) were...

Analysis of wheat commercialization in Ethiopia: The case of SARD-SC wheat project innovation platform sites

In Ethiopia, wheat is becoming an essential source of income for farmers even though it is still a fundamental food crop. While the major proportion is kept for consumption, farmers sell part of their wheat produce. The main objectives of this paper are to assess the level of commercialization and its determinants of wheat producers in the four major producing regions. Quantitative primary data was collected from...

Coffee pruning: Importance of diversity among genotypes of Coffea arabica

The renovation of Arabica coffee crops located in mountain regions should be based on the use of new improved genotypes and increased plant density, which require the establishment of an adequate pruning system. Little is known about the response of improved genotypes to pruning, therefore this study was done to evaluate the vegetative and reproductive recovery after pruning of genotypes of Arabica coffee cultivated in...

Artificial neural networks in predicting energy density of Bambusa vulgaris in Brazil

In this study, the physical and chemical characteristics of Bambusa vulgaris ex J.C. Wendl. var.vulgaris (Bambusa vulgaris) aged 1, 2 and 3 years were evaluated. The objective was to train, validate and evaluate the efficiency of artificial neural networks (ANNs) as predictive tools to estimate bamboo stem energy density grown commercially in northeastern Brazil. For that, samples were collected in a commercial...
