Participatory evaluation of sorghum technologies in the marginal dryland zones of Wag-lasta, Ethiopia

Cogent Food & Agriculture, 2019
Despite dryland areas are diverse in agro-ecology; technological recommendations are summative and based on researchers’ on-station genetic traits, which deprived the farmers’ preference, the economic and technical efficiencies.

TreeSpider: In‐Canopy Exploration With Tether‐Based Aerial Modular Arms

Advanced Robotics Research, EarlyView.
A tethered drone with perching arms and a 360° ring enables unprecedented maneuverability within dense forest canopies. By dynamically adjusting tether length and decoupling pitch from the frame, it navigates between branches, senses multiple trees, and interacts physically with foliage.

Communal land and agricultural productivity [PDF]

Journal of Development Economics, 2019
This paper quantifies the aggregate impact of communal land tenure ar- rangements that prevail in Sub-Saharan Africa. Such tenure regimes limit land transfer- ability by prohibiting sales, subjecting rented-out land to the risk of expropriation, and redistributing it to existing farmers in a progressive fashion.

Long‐Term Elevated CO2 Improves Soil Health and Rice Yields in Paddy Fields

Advanced Science, EarlyView.
Combining the two longest‐running rice free‐air CO2 enrichment experiments with a global data synthesis, this study demonstrates that long‐term elevated CO2 consistently enhances soil health. In rice paddies, this improvement sustains the CO2 fertilization effect over decades.

BioCNTs Mediated Delivery of Systemically Mobile Small RNAs via Leaf Spray to Control Both Tomato DNA and RNA Viruses

Advanced Science, EarlyView.
A carbon nanotube‐based biopesticide system (BioCNTs) enables efficient delivery and systemic movement of RNAi molecules to control major tomato viruses. By integrating shRNA and tRNA‐like structures (TLS) with BioCNTs, this green and scalable approach achieves long‐term silencing and high antiviral efficacy through simple foliar spraying.

Short-term microbial community dynamics induced by 13C-labeled maize root, its derived biochar and NPK in long-term amended soil

Biochar
Crop residues and their derived biochar are frequently used for their potential to improve grain yield, soil fertility and carbon (C) sequestration. However, the effects of root are often overlooked, and the effects of chemical fertilizer (NPK) combined ...

Structural and Functional Characterization of EXPO‐Derived Extracellular Vesicles in Plants

Advanced Science, EarlyView.
In this study, 3D electron tomography (ET), cryo‐ET, and immunogold transmission electron microscopy (TEM) are employed to characterize plant extracellular vesicles (EVs) under physiological conditions. EVs are classified into three distinct categories according to their size, content, and molecular‐marker profiles. Furthermore, Exo70E2‐positive medium
