Non­Destructive Testing of Growth Productivity

open access: yesСельскохозяйственные машины и технологии, 2021
The necessary condition for obtaining high yields is the management of plant production processes in closed artificial agroecosystems. It is important to control the intensity of these processes in a dynamic mode.

Modeling batch annealing process using data mining techniques for cold rolled steel sheets [PDF]

open access: yes, 2011
The annealing process is one of the important operations in production of cold rolled steel sheets, which significantly influences the final product quality of cold rolling mills.

Analysis of Environmental Effects on Leaf Temperature under Sunlight, High Pressure Sodium and Light Emitting Diodes.

open access: yesPLoS ONE, 2015
The use of LED technology is commonly assumed to result in significantly cooler leaf temperatures than high pressure sodium technology. To evaluate the magnitude of this effect, we measured radiation incident to and absorbed by a leaf under four ...

Colored Shade Nets Can Relieve Abnormal Fruit Softening and Premature Leaf Senescence of “Jumeigui” Grapes during Ripening under Greenhouse Conditions

open access: yesPlants, 2022
High temperature causes premature grape leaf senescence, abnormal berry softening, and shortening of the fruiting period. Furthermore, the fruit quality and yield are severely affected.

Idealized model for changes in equilibrium temperature, mixed layer depth, and boundary layer cloud over land in a doubled CO2 climate [PDF]

open access: yes, 2010
An idealized equilibrium model for the undisturbed partly cloudy boundary layer (BL) is used as a framework to explore the coupling of the energy, water, and carbon cycles over land in midlatitudes and show the sensitivity to the clear‐sky shortwave flux,

A short-term cooling of root-zone temperature increases bioactive compounds in baby leaf Amaranthus tricolor L.

open access: yesFrontiers in Plant Science, 2022
Leafy vegetables that are offered as seedling leaves with petioles are referred to as baby leaf vegetables. One of the most nutritious baby leaves, amaranth (Amaranthus tricolor L.), contains several bioactive compounds and nutrients.

Energy saving: From engineering to crop management [PDF]

open access: yes, 2011
In greenhouse horticulture, energy costs form an increasingly larger part of the total production costs. Energy is primarily used for temperature control, reduction of air humidity, increase of light intensity and CO2 supply.

Cool‐Season Turfgrass Color and Growth Calibrated to Leaf Nitrogen

open access: yesCrop Science, 2007
Tissue N analysis a tool available for N management of turfgrass. However, peer‐reviewed calibration studies to determine optimum tissue N values are lacking. A field experiment with a mixed cool‐season species lawn and a greenhouse experiment with Kentucky bluegrass (Poa pratensis L.) were conducted across 2 yr, each with randomized complete block ...

Impacts of climate change on rice production in Africa and causes of simulated yield changes [PDF]

open access: yes, 2019
This study is the first of its kind to quantify possible effects of climate change on rice production in Africa. We simulated impacts on rice in irrigated systems (dry season and wet season) and rainfed systems (upland and lowland).

Observations on the Overwintering Potential of the Striped Cucumber Beetle (Coleoptera: Chrysomelidae) in Southern Minnesota [PDF]

open access: yes, 2018
The striped cucumber beetle, Acalymma vittatum (Fabricius) (Coleoptera: Chrysomelidae), is an important pest of cucurbit crops. However, the overwinter- ing capacity of this pest in temperate regions is poorly understood.
