Seeds of change: The impact of Ethiopia's direct seed marketing approach on smallholders' seed purchases and productivity

American Journal of Agricultural Economics, EarlyView.
Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market

Improving access to new technologies: An experiment with Kenyan input sellers

American Journal of Agricultural Economics, EarlyView.
Abstract Agrodealers play a critical role in rural economies, selling essential inputs for agricultural production, stocking new products, and providing farmers with technical advice. However, uncertainty can discourage them from stocking newer, less familiar products, limiting the availability of innovative technologies and leading to market failures ...

Chromosomal Distribution of Genes Conferring Tolerance to Abiotic Stresses Versus That of Genes Controlling Resistance to Biotic Stresses in Plants [PDF]

, 2020
Tolerance to abiotic stresses caused by environmental conditions can prevent yield loss in crops for sustaining agricultural productivity [1]. Resistance to biotic stresses caused by diseases and insects can prevent or reduce yield loss in crops [2]. For

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

American Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

ABIOTIC AND BIOTIC STRESS FACTORS IN GRAINS

, 2023
It is known that people in the world mix a large part of their daily calorie needs from cereals and products obtained from cereals. As a result of breeding studies carried out in order to meet the need in parallel with the increasing population,

Detection of biotic and abiotic stresses in crops by using hierarchical self organizing classifiers

, 2017
Hyperspectral signatures can provide abundant information regarding health status of crops; however it is difficult to discriminate between biotic and abiotic stress.

Hepatic morphology and serum biochemical profile according to dry and rainy seasons in Pygocentrus nattereri (Characiformes: Serrasalmidae)

The Anatomical Record, EarlyView.
Abstract This study investigated the physiological and morphological adaptations of the liver of the carnivorous fish Pygocentrus nattereri (piranha) in response to seasonal variations (dry and rainy seasons) in the Brazilian Pantanal. The objective was to describe how the liver, a central organ in metabolic regulation, responds to environmental ...

Reducing Cooling Costs for Sustainable Food Biomanufacturing With Thermotolerant Cupriavidus necator H16 Mutant

Biotechnology and Bioengineering, EarlyView.
With a thermotolerant C. necator mutant the SCP production costs can be decreased by $0.98/kg. ABSTRACT Autotrophic CO2 conversion to Single Cell Protein (SCP) using H2 and O2 is gaining commercial traction for food and feed production. Cupriavidus necator H16 is a key chassis organism for this “knallgas” fermentation, but industrial operation is ...
