A field experiment was conducted during 2018-19 to study weed diversity and their management by using broad spectrum herbicide. The laid out in randomized complete block design with three replications. vegetation analysis done before herbicide treatment. Herbicides evaluated were glufosinate-ammonium 13.5% SL at 375, 495 615 g a.i./ha, diuron 80% WP 1600 a.i./ha paraquat dichloride 24% 500 alon...

Healthy soils form the basis of sustainable viticulture, where soil characteristics have a direct impact on wine quantity and quality. Soil not only provides water nutrients to vines, but is also living medium containing micro- macroorganisms that perform many ecological functions provide ecosystem services. These organisms are involved in processes, from decomposing organic matter providing mi...

Agricultural pesticide use has increased worldwide during the last several decades, but the long-term fate, storage, and transfer dynamics of pesticides in a changing environment are poorly understood. Many pesticides have been progressively banned, but in numerous cases, these molecules are stable and may persist in soils, sediments, and ice. Many studies have addressed the question of their p...

The relationships between variations in grapevine (Vitis vinifera L. cv. Pinot noir) growth and resulting fruit and wine phenolic composition were investigated. The study was conducted in a commercial vineyard consisting of the same clone, rootstock, age, and vineyard management practices. The experimental design involved monitoring soil, vine growth, yield components, and fruit composition (so...

This article presents a practical tool for optimally scheduling wine grape harvesting operations taking into account both operational costs and grape quality. We solve a mixed-integer linear programming model to support harvest scheduling, labor allocation, and routing decisions. A quality loss function is used to represent wine quality reduction at each vineyard block due to premature or defer...

Microorganisms associated with Vitis vinifera (grapevine) can affect its growth, health and grape quality. The aim of this study was to unravel the biodiversity of the bacterial rhizosphere microbiota of grapevine in an integrated pest management vineyard located in Piedmont, Italy. Comparison between the microbial community structure in the bulk and rhizosphere soil (variable: space) were perf...

This work focuses on the development of a user interface suitable for targeted spraying, using a robot that is teleoperated along the vineyard rows. A prototype of the spraying interface was developed and the usability of three different interaction modes was investigated. Fifty participants were asked to use the three devices to select grape clusters taken from a simulated robot moving along r...
