Abstract:

Yield issues are crucial for winegrowers. In France, yield is often lower than winegrowers’ objectives, and there is a need to understand the causes and magnitude of yield variability in vineyard systems. The yield formation process for grapevine (Vitis vinifera) takes place over two consecutive years. Grapevine is also characterised by a limited control of phenology, a winter dormancy period and the existence of storage organs. We adapted the regional agronomic diagnosis approach as defined by Doré et al. (1997) to quantify grapevine yield variability in two complementary case studies. The re

Abstract:

The nitrogen nutrition index (NNI) is a significant agronomic statistic used to assess the nitrogen nutrition status of crops. The use of remote sensing to invert it is crucial for accurately diagnosing and managing nitrogen nutrition in crops during critical periods. This study utilizes the UHD185 airborne hyperspectral imager and the ASD Field Spec3 portable spectrometer to acquire hyperspectral remote sensing data and agronomic parameters of the winter wheat canopy during the nodulation and flowering stages. The objective is to estimate the NNI of winter wheat through a winter wheat nitroge

In intensive cultivation technology of spring barley inhibition by 2-chloroethylphosphonic growth last internode main stem after flowering can generate an increase in the tillers by increasing increase of productive tillering decreasing by 2-4 tilt stems at an average yield of 4.5 t / ha of spring barley. In this case, there is no need to apply the agro-technical measures to reduce the probability of crop lodging - reducing seeding rates and sparse seeding, all elements of the maximum level of productivity combined with the effect of the inhibitor on the vertical stability of the crop and the

Abstract:

Traditionally farmers have used their perceptual sensorial systems to diagnose and monitor their crops health and needs. However, humans possess five basic perceptual systems with accuracy levels that can change from human to human which are largely dependent on the stress, experience, health and age. To overcome this problem, in the last decade, with the help of the emergence of smartphone technology, new agronomic applications were developed to reach better, cost-effective, more accurate and portable diagnosis systems. Conventional smartphones are equipped with several sensors that could be

Abstract:

Dieback in the vineyards is causing a long-term decline in the productivity of the vine stock and/or its sudden or gradual premature death, related to a number of different factors. It is a problem in all wine regions around the world. Its economic importance was estimated to represent €2 billion turnover in 2020 if the trend in yield loss continues at the same pace. How do we diagnose dieback in the wine-growing holdings to provide a better understanding of the risks and to respond? The aim of the work is to identify the factors to be taken into consideration in the development of a dieback s

Abstract:

Crop production in the high-rainfall zone of Western Australia (>450 mm average annual rainfall) is an increasing proportion of the state’s total farming system since the 1990s, when the profitability of animal production based on improved pastures was threatened. However, the yields of the dominant crops barley, canola and oats have often been insufficient to maintain whole-farm productivity in the changed system. The aim of this study was to test the diagnostic approach to agronomic research as a means of increasing crop yields. Experiments were conducted at two farm sites over 5 years wi

Ditylenchus destructor and D. dipsaci are important nematodes that have a significant economic impact on agronomic and horticultural plants worldwide. Microscopic observation alone may not distinguish between D. destructor and D. dipsaci. Accurate and rapid identification of these two species is essential for effective pest management. In the present study, a species-specific PCR assay was developed to detect and differentiate D. destructor and D. dipsaci based on the rDNA-ITS sequences. The primers developed in this study can specifically amplify fragments of DNA from D. destructor and D. dip

In order to study the complex relationships with genetic and non-genetic factors, the application of Bayesian network tools will help understand and accelerate plant breeding progress and improve the efficiency of crop

Under ideal conditions of nitrogen (N), maize (Zea mays L.) can grow to its full potential, reaching maximum plant height (PH). As a rapid and nondestructive approach, the analysis of unmanned aerial vehicles (UAV)-based imagery may be of assistance to estimate N and height. The main objective of this study is to present an approach to predict leaf nitrogen concentration (LNC, g kg−1) and PH (m) with machine learning techniques and UAV-based multispectral imagery in maize plants.

Abstract:

Modern intensive agricultural systems generally focus on the productivity of monocultures. They are characterized by a low diversity of crops, with uniform and symmetrical planting layouts. They largely rely on the utilization of chemical inputs. They are widely denounced for their negative environmental impacts. In this context, the ecological intensification framework proposes the exploitation of biodiversity in order to better achieve such ecosystem services and soil conservation. Intercropping, i.e., the simultaneous growth of two or more crops mixed in the same field, appears to have the
