Mechanical properties of drying plant roots: Evolution of the longitudinal Young's modulus of chick-pea roots with dessication [PDF]

arXiv, 2018
Mechanical characterizations of plant roots are of primary importance in geophysics and engineering science for implementing mechanical models for the stability of root reinforced-soils, as well as in agronomy and soil science for understanding the penetration of roots in soils and optimizing crop. Yet the mechanical properties of plant roots depend on

Weed Recognition using Deep Learning Techniques on Class-imbalanced Imagery [PDF]

arXiv, 2021
Most weed species can adversely impact agricultural productivity by competing for nutrients required by high-value crops. Manual weeding is not practical for large cropping areas. Many studies have been undertaken to develop automatic weed management systems for agricultural crops.

Economic Feasibility of Crop‐Livestock Integration System in Brazil

Agribusiness, EarlyView.
ABSTRACT We investigate the economic feasibility of the Brazilian crop‐livestock integration system. Under this system, the Brazilian farmer can produce soybeans, corn, and graze for cattle on the same land during one crop year. This technology can substantially increase agricultural production in the country.

ZmCCA1a on Chromosome 10 of Maize Delays Flowering of Arabidopsis thaliana

Frontiers in Plant Science, 2020
Maize (Zea mays) is a major cereal crop that originated at low latitudes, and thus photoperiod sensitivity is an important barrier to the use of tropical/subtropical germplasm in temperate regions.

Charting the Path to Increased Oil Palm Output in Ghana Beyond Area Expansion: Technology or Managerial Capacity — Which Leads the Way?

Agribusiness, EarlyView.
ABSTRACT This study sets out to investigate the prospects for raising oil palm output in sub‐Saharan Africa, particularly Ghana, without further expansion of cropland. Given global concerns about oil palm's role in deforestation and land use change, the focus is on enhancing productivity on existing farmlands.
