Identifying most promising agronomic adaptation strategies to close rainfed rice yield gap in future: a model-based assessment

Journal of Water and Climate Change, 2021
There is an increasing consensus that climate change may have a high negative impact on crop yield, and that it will affect farmers in developing and least developed counties the most.

Stochastic Metallic-Glass Cellular Structures Exhibiting Benchmark Strength [PDF]

, 2008
By identifying the key characteristic “structural scales” that dictate the resistance of a porous metallic glass against buckling and fracture, stochastic highly porous metallic-glass structures are designed capable of yielding plastically and inheriting

Determination and Assessments the Yield Gap Between the Wheat Yield and Potential Yield in Turkey

Turkish Journal of Agriculture: Food Science and Technology, 2018
Knowing the current and the potential production amount of wheat is essential to meet the growing needs. Yield is determined by many factors. The main factors that limit the potential yield are genetic characteristics, and climatic factors such as ...

Closing the yield gap of soybean (Glycine max (L.) Merril) in Southern Africa: a case of Malawi, Zambia, and Mozambique

Frontiers in Agronomy, 2023
IntroductionSmallholder farmers in Sub-Saharan Africa (SSA) are increasingly producing soybean for food, feed, cash, and soil fertility improvement. Yet, the difference between the smallholder farmers’ yield and either the attainable in research fields ...

NITROGEN FERTILIZATION FOR MAIZE BASED ON ATTAINABLE YIELD AND SOIL ORGANIC MATTER CONTENT

Agrociencia, 2022
Agricultural soils generally do not provide enough N to satisfy crop needs, so it is necessary to apply it as fertilizer. This supply can be estimated by chemical analysis of the soil and, based on this and the needs of the plant, nitrogen fertilization recommendations are made for the crops.

Large scale assessment of the production process and rice yield gap analysis by comparative performance analysis and boundary-line analysis methods

Italian Journal of Agronomy, 2019
To reduce the yield gap, specifying yield constraints in a particular area is necessary. A complete yield gap assessment method must provide information regarding potential yield, actual yield, and causes of the gap and their importance.

Preliminary Design of Reactive Distillation Columns [PDF]

, 2005
A procedure that combines feasibility analysis, synthesis and design of reactive distillation columns is introduced. The main interest of this methodology lies on a progressive introduction of the process complexity.

Effect of nitrogen and water deficit type on the yield gap between the potential and attainable wheat yield [PDF]

Chilean journal of agricultural research, 2015
Water deficit and N fertilizer are the two primary limiting factors for wheat yield in the North China plain, the most important winter wheat (Triticum aestivum L.) production area in China. Analyzing the yield gap between the potential yield and the attainable yield can quantify the potential for increasing wheat production and exploring the limiting ...
