Enhancing crop growth in rooftop farms by repurposing CO2 from human respiration inside buildings

open access: yesFrontiers in Sustainable Food Systems, 2022
Integrating cities with the surrounding environment by incorporating green spaces in creative ways would help counter climate change. We propose a rooftop farm system called BIG GRO where air enriched with carbon dioxide (CO2) produced through ...

Aphidophagous Coccinellids in Alfalfa, Small Grains, and Maize in Eastern South Dakota [PDF]

open access: yes, 2017
In a 13-year study of aphidophagous coccinellids associated with alfalfa (Medicago sativa), maize (Zea mays), and small grain crops in eastern South Dakota, the following species were consistently associated with the crops: Hippodamia convergens, H ...

Crop modelling in agricultural crops

open access: yesCurrent Science, 2023
With limited land resources and a growing population, agricultural output is under considerable strain. New technology is necessary for overcoming these issues and advising farmers, legislators and other decision-makers on adopting sustainable agriculture despite global climate variations. This has led to the crop simulation models that illustrate crop

Transcription Factors Associated with Abiotic and Biotic Stress Tolerance and Their Potential for Crops Improvement

open access: yesGenes, 2019
In field conditions, crops are adversely affected by a wide range of abiotic stresses including drought, cold, salt, and heat, as well as biotic stresses including pests and pathogens. These stresses can have a marked effect on crop yield.

The green, blue and grey water footprint of crops and derived crops products

open access: yes, 2011
This study quantifies the green, blue and grey water footprint of global crop production in a spatially-explicit way for the period 1996–2005. The assessment improves upon earlier research by taking a high-resolution approach, estimating the water ...

Plant cell wall and the mechanisms of resistance to pathogens

open access: yesВавиловский журнал генетики и селекции, 2016
A huge variety of phytopathogens (viruses, bacteria, fungi) are potentially able to infect plant tissues and cause diseases. Numerous plant genes control a complex network of defense mechanisms based on both constitutive and inducible processes. The cell

Boron content in soils under increasing magnesium and sulphur doses in a field experiment

open access: yesPlant, Soil and Environment, 2020
The three-year field experiment (2015-2017) with graded doses of magnesium (Mg) and sulphur (S) was carried out at the Humpolec experimental station (49.5546239N, 15.3485489E; Czech Republic). The interactions between boron (B), Mg and S in the soil were

Biostimulants Application in Horticultural Crops under Abiotic Stress Conditions

open access: yesAgronomy, 2019
Abiotic stresses strongly affect plant growth, development, and quality of production; final crop yield can be really compromised if stress occurs in plants’ most sensitive phenological phases.

Addressing regional relationships between white‐tailed deer densities and land classes

open access: yesEcology and Evolution, 2021
White‐tailed deer (Odocoileus virginianus) populations have recovered to about 30 million animals in the United States, but land cover has changed during the interval of recovery.

Viewpoints: Biofuels and trees in humid tropical countries of West Africa. Experts address the question: Can the growing demand for biofuels be met without threatening food security? [PDF]

open access: yes, 2009
In the humid tropics, with rich tree crops such as cocoa and abundant staples such as cassava, is there any place for biofuels? Using staple and annual crops as biofuels is dangerous for food security.
