John T. O'Donovan

What is he best known for?

The fields of study he is best known for:

• Agronomy
• Agriculture
• Ecology

John T. O'Donovan spends much of his time researching Agronomy, Weed, Canola, Crop and Weed control. His research brings together the fields of No-till farming and Agronomy. His Weed research is multidisciplinary, relying on both Cover crop, Cropping system and Shoot, Horticulture.

His study focuses on the intersection of Crop and fields such as Brassica with connections in the field of Crimson clover, Secale and Field experiment. John T. O'Donovan studied Weed control and Biomass that intersect with Cultural control and Plant density. In his research, Yield is intimately related to Seeding, which falls under the overarching field of Cultivar.

His most cited work include:

• Influence of the Relative Time of Emergence of Wild Oat (Avena fatua) on Yield Loss of Barley (Hordeum vulgare) and Wheat (Triticum aestivum)1 (213 citations)
• The use of Biologically Realistic Equations to Describe the Effects of Weed Density and Relative Time of Emergence on Crop Yield (197 citations)
• Recent Weed Control, Weed Management, and Integrated Weed Management (132 citations)

What are the main themes of his work throughout his whole career to date?

John T. O'Donovan focuses on Agronomy, Canola, Weed, Hordeum vulgare and Crop. His studies link No-till farming with Agronomy. The various areas that John T. O'Donovan examines in his Canola study include Fertilizer, Field pea, Crop rotation, Glyphosate and Yield.

In his work, Organic farming is strongly intertwined with Poaceae, which is a subfield of Weed. His study in Hordeum vulgare is interdisciplinary in nature, drawing from both Avena fatua, Cropping system, Crop yield and Sowing. His Cultivar study combines topics from a wide range of disciplines, such as Competition and Germination.

He most often published in these fields:

• Agronomy (90.91%)
• Canola (44.85%)
• Weed (27.88%)

What were the highlights of his more recent work (between 2013-2021)?

• Agronomy (90.91%)
• Canola (44.85%)
• Crop (21.82%)

In recent papers he was focusing on the following fields of study:

His scientific interests lie mostly in Agronomy, Canola, Crop, Brassica and Fertilizer. Crop rotation, Hordeum vulgare, Green manure, Field pea and Growing season are the primary areas of interest in his Agronomy study. His research in Hordeum vulgare tackles topics such as Cropping system which are related to areas like Sowing, Hectare, Nitrous oxide, Winter wheat and Weed control.

His studies in Canola integrate themes in fields like Crop yield, Glufosinate, Legume and Yield. His Brassica study combines topics in areas such as Bolting, Glyphosate, Herbivore and Diamondback moth. His work in Fertilizer tackles topics such as No-till farming which are related to areas like Soil test, Soil management and Bulk soil.

Between 2013 and 2021, his most popular works were:

• Diversifying crop rotations with pulses enhances system productivity. (100 citations)
• Legumes can reduce economic optimum nitrogen rates and increase yields in a wheat–canola cropping sequence in western Canada (48 citations)
• Rotational Effects of Legumes and Non-Legumes on Hybrid Canola and Malting Barley (42 citations)

In his most recent research, the most cited papers focused on:

• Agronomy
• Agriculture
• Ecology

His main research concerns Agronomy, Canola, Green manure, Crop rotation and Field pea. His work in Agronomy is not limited to one particular discipline; it also encompasses Soil organic matter. He combines subjects such as Phenology, Plant density, No-till farming, Yield and Minimum tillage with his study of Canola.

The Green manure study which covers Soil fertility that intersects with Plant nutrition. His research in Field pea intersects with topics in Legume and Hordeum vulgare. His Crop research includes themes of Perennial plant, Field experiment, Avena fatua, Weed and Silage.
