Corn response to long‐term seasonal weather stressors: A review

Crop Science, Volume 63, Issue 6, Page 3210-3235, November/December 2023., 2023
Abstract Long‐term weather patterns (environmental conditions or stresses exceeding 10 days in length) have the potential to influence corn (Zea mays L.) growth, development, and yield. This review summarizes the current knowledge (with emphasis placed on the Midwestern U.S. production environment) on how long‐term weather conditions affect corn growth

Accelerated leaf appearance and flowering in maize after four decades of commercial breeding

Crop Science, Volume 63, Issue 5, Page 2750-2762, September/October 2023., 2023
Abstract Maize breeding programs have indirectly altered many plant traits; however, our knowledge of some important phenological traits remains unexplored. One such trait is leaf appearance rate, which is crucial for predicting maize development. We studied 40 short‐season (103‐day) and 38 long‐season (111‐day) hybrids released from 1980 to 2020 by ...

Water-Soluble Carbohydrate Recovery in Pastures of Perennial Ryegrass (Lolium perenne L.) and Pasture Brome (Bromus valdivianus Phil.) Under Two Defoliation Frequencies Determined by Thermal Time

Agriculture, 2020
The objectives of the experiment were to (i) examine the dynamics of WSC use and the recovery of leaf sheaths and blades of Bromus valdivianus Phil. and Lolium perenne L. subjected to two defoliation frequencies (DFs) determined by thermal time (TT); (ii)

A morphogenetic crop model for sugar-beet (Beta vulgaris L.) [PDF]

, 2008
This paper is the instructions for the proceeding of the International Symposium on Crop. Sugar beet crop models have rarely taken into account the morphogenetic process generating plant architecture despite the fact that plant architectural plasticity ...

Base temperature, thermal time and phyllochron of escarole cultivation [PDF]

Horticultura Brasileira, 2018
ABSTRACT The objective of this study was to determine the base temperature of escarole and to apply in the phenological analysis of crop during four growing periods. The study was carried out with escarole (Chicorium endivia) ‘Escarola Lisa’ cultivar, at the Federal University of Santa Maria, campus Frederico Westphalen-RS. The experiment was performed

Tiller demography of tall fescue and tall wheatgrass cut at different times during the reproductive phase

Grassland Research, Volume 2, Issue 2, Page 120-128, June 2023., 2023
The present work aimed to study the tiller demography of tall fescue (TF) and tall wheatgrass (TW) when reproductive tillers are removed at different stages of plant development. The results will help to improve management recommendations to obtain denser TF and TW swards.

Improving wheat productivity through integrated management of Avena ludoviciana

Agronomy Journal, Volume 115, Issue 3, Page 1478-1488, May/June 2023., 2023
Abstract In Australia, wheat planting is preferred in June compared with May to kill early cohorts of weeds before planting, particularly in fields with a history of high weed infestation. However, wheat grain yield is often reduced for June planting.

[i]In silico[/i] system analysis of physiological traits determining grain yield and protein concentration for wheat as influenced by climate and crop management [PDF]

, 2015
Genetic improvement of grain yield (GY) and grain protein concentration (GPC) is impeded by large genotype×environment×management interactions and by compensatory effects between traits.

Simulated impacts of winter rye cover crop on continuous corn yield and soil parameters

Agronomy Journal, Volume 115, Issue 3, Page 1114-1130, May/June 2023., 2023
Abstract Cover crops (CC) provide numerous ecosystem services such as improving soil health, reducing nutrient loss, increasing productivity, and mitigating greenhouse gas emission. However, adoption of CC has been hindered by perceived negative impacts on main crop productivity and additional production costs.
