The Effect of Vermicompost on the Biochemical Properties of Hazelnuts
To date, no studies have been conducted exploring the effect of vermicompost on the biochemical properties of hazelnut; therefore, more research is needed on this subject. This study was conducted between 2018 and 2020 to determine the effect of vermicompost (3–5 kg/ocak; VM1 and VM2, respectively) on total fat and protein content, total carbohydrate and ash, […]
The effects of kernel feeding by Halyomorpha halys (Hemiptera: Pentatomidae) on commercial hazelnuts.
Stål, the brown marmorated stink bug (Hemiptera: Pentatomidae), is an invasive pest with established populations in Oregon. The generalist feeding habits of suggest it has the potential to be a pest of many specialty crops grown in Oregon, including hazelnuts, L. The objectives of this study were to: 1) characterize the damage to developing hazelnut kernels resulting […]
Halyomorpha halys, a serious threat for hazelnut in newly invaded areas.
Following its first detection, Halyomorpha halys has become a key pest in many crops in NW Italy. In this area, one of the most important crops is hazelnut, in which the species can cause severe damage through feeding on nuts. Therefore, semi-field trials were carried out in NW Italy to compare the harmfulness of H. halys with that of […]
Comparing the feeding damage of the invasive brown marmorated stink bug to a native stink bug and leaffooted bug on California pistachios.
California currently produces about a quarter of the world’s pistachios. Pistachio nuts are susceptible to feeding by stink bugs and leaffooted bugs; therefore, the invasive presence of the highly polyphagous brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), is a concern to California pistachio growers. We aimed to assess the potential of H. halys to cause yield loss […]
Field Survival of the Brown Marmorated Stink Bug Halyomorpha halys (Hemiptera: Pentatomidae) on California Tree Crops.
Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) is a polyphagous insect pest that has invaded much of the United States, including California. Despite model predictions that regions in California like the agriculturally important Central Valley are suitable, H. halys populations and the occurring crop damage are distinctly lower than in regions of the East Coast. To evaluate […]
Unraveling Genetic Diversity Amongst European Hazelnut (Corylus avellana L.) Varieties in Turkey.
European hazelnut (Corylus avellana) is a diploid (2n = 22), monecious and wind-pollinated species, extensively cultivated for its nuts. Turkey is the world-leading producer of hazelnut, supplying 70-80% of the world's export capacity. Hazelnut is mostly grown in the Black Sea Region, and maintained largely through clonal propagation. Understanding the genetic variation between hazelnut varieties, […]
The HADES yield prediction system–a case study on the Turkish hazelnut sector.
Crop yield forecasting activities are essential to support decision making of farmers, private companies and public entities. While standard systems use georeferenced agro-climatic data as input to process-based simulation models, new trends entail the application of machine learning for yield prediction. In this paper we present HADES (HAzelnut yielD forEcaSt), a hazelnut yield prediction system, […]
Variation of Morphological, Agronomic and Chemical Composition Traits of Local Hazelnuts Collected in Northern Spain.
Hazelnut is a traditional crop in northern Spain, where it grows wild as well as being cultivated. A field collection of 41 local and 17 non-local accessions, including 15 well-known cultivars, was established at SERIDA in Villaviciosa, Spain. Here, phenotypic variation was documented for phenological and morphological traits and chemical composition. A large degree of […]
Genotypic and Environmental Variations in Kernel Color Indices in the Main Almond (Prunus dulcis (Mill.) DA Webb) Cultivars Grown in North-Eastern Morocco.
Color indices are important quality traits that define the consumer visual acceptance and agroindustrial preferences. Little is known regarding these properties in the commercial almond cultivars grown in Morocco. This work aimed at investigating kernel color indices in five cultivars, namely, "Fournat de Brézenaud," "Tuono," "Ferragnès," "Ferraduel," and "Marcona." Color indices consisted in the following: […]
Effect of Tractor Speed and Spray Application Volume on Severity of Scab at Different Heights in the Canopy of Tall Pecan Trees.
Scab (caused by Venturia effusa) is the most important yield-limiting disease of pecan in the southeastern USA. On susceptible cultivars, the disease is managed using fungicides, but spray coverage is an issue in tall trees. In four experiments we used an air-blast sprayer to compare scab severity on fruit at 5.0 to 15.0 m height […]
