Rice is globally the most important food crop and there a dire need to feed ever-increasing population by improving its productivity. It has been realised that diseases are major impediment towards enhancing productivity of this crop. Despite advent modern effective disease control measures such as use chemicals, bioagents resistant varieties; agronomic practices still play vital role in manage...
Exploring the relationship between agricultural nitrogen (N) loading on a dairy farm and groundwater reactive N concentration such as nitrate (NO3) is particularly challenging in areas underlain by thin soils and karstified limestone aquifers. The present study on such a site aims to relate changes in detailed paddock specific agronomic N-loading, hydrogeological and geological site characteris...
The recently discovered ammonia-oxidizing archaea (AOA) have been suggested as contributors to the first step of nitrification in terrestrial ecosystems, a role that was previously assigned exclusively to ammonia-oxidizing bacteria (AOB). The current study assessed the effects of agricultural management, specifically amendment of soil with biosolids or synthetic fertilizer, on nitrification rat...
AN IMPROVED UNDERSTANDING of the terms fertilizer-use efficiency (FUE) and maximum economic yield (MEY) has likely never been as important to western Canadian agronomists and farmers as it is today. The objective of PPI/PPIC and Foundation for Agronomic Research (FAR) sponsored research projects in western Canada is to support a better understanding of the role of phosphorus (P) and potassium (...
Advances in automation and data science have led agriculturists to seek real-time, high-quality, high-volume crop data to accelerate crop improvement through breeding and to optimize agronomic practices. Breeders have recently gained massive data-collection capability in genome sequencing of plants. Faster phenotypic trait data collection and analysis relative to genetic data leads to faster an...
A main task in agriculture production is field management of water and fertilizer. Excessive fertilizer and water application not only waste resource but also pollute the environment. The traditional principle of digital agriculture can only apply in flat or plain place where a large field usually should be partitioned evenly into many little grids and thus decisions on grid-specific agronomic ...
87 A retrovirus insertion causes abnormal expression of the tyrosinase gene in recessive white chickens. C. M. Chang*, J. L. Coville, J. P. Furet, A. Oulmouden, G. Coquerelle, D. Gourichon, and M. Tixier-Boichard, National Institute for Agronomic Research, UMR INRA/INA P-G, Jouy-en-Josas, France, National Institute for Agronomic Research, UEPSD, INRA, Jouy-en-Josas, France, National Institute f...
Purpose of This Publication Knowledge of soil phosphorus (P) levels is an essential component of nutrient management planning for crop production and for tools that assess the risk of P loss from agricultural fields. Historically, soil P testing has been used to estimate P availability for crops and is now being used directly or as a component of P indices to assess the risk of P loss from fiel...
The gap between current average global wheat yields and that achievable through best agronomic management and crop genetics is large. This is notable in intensive wheat rotations which are widely used. Expectations are that this gap can be reduced by manipulating soil processes, especially those that involve microbial ecology. Cross-year analysis of the soil microbiome in an intensive wheat cro...
Many vocabularies and ontologies are produced to represent and annotate agronomic data. By reusing the NCBO BioPortal technology, we have already designed and implemented an advanced prototype ontology repository for the agronomy domain. We plan to turn that prototype into a real service to the community. The AgroPortal project aims at reusing the scientific outcomes and experience of the biome...
