Combining phosphorus placement and water saving technologies enhances rice production in phosphorus-deficient lowlands
Published 2019“…Field and pot experiments were set up to evaluate combinations of water saving technologies and micro-dose P placement methods (i.e. the localized application of a small P dose to a sub-surface area, often combined with seeds into the planting hole) with due attention to treatment effects on root architecture. A two-year field experiment was set up in a lowland rice field in Tanzania with factorial combinations of different levels of water supply (field capacity, alternating wetting drying, permanent flooding) and P application (no P; 3.45 and 6.90 kg ha−1 placement versus 25 kg ha−1 broadcast), thereby testing residual effects in year 2. …”

Using high-resolution imagery and deep learning to classify land-use following deforestation: a case study in Ethiopia
Published 2022“…In this research, we assess the potential of different satellite data modalities (single-date, multi-date, multi-resolution, and an ensemble of multi-sensor images) for classifying land-use following deforestation in Ethiopia using the U-Net deep neural network architecture enhanced with attention. We performed the analysis on satellite image data retrieved across Ethiopia from freely available Landsat-8, Sentinel-2 and Planet-NICFI satellite data. …”

Genome-wide association study of a Guinea grass (Megathyrsus maximus) diversity panel reveals the genetic basis of agronomic and nutritional traits
Published 2025“…Using three complementary GWAS models (Bayesian-information and Linkage-disequilibrium Iteratively Incorporating Knowledge (BLINK), the Fixed and Random Model Circulating Polynomial Unification (FarmCPU), and the Multiple Loci Mixed Model (MLMM)), we identified 25 significant marker-trait associations (MTAs) spanning three major trait categories: (i) phenological and plant-architecture; (ii) nutritional and digestibility; and (iii) productivity and nitrogen-use traits, evaluated under wet-season, dry-season, and greenhouse conditions. …”
