Genotype by environment interaction analysis for fall armyworm (Spodoptera frugiperda) response and yield stability of maize hybrids (Zea maize L.) in southern Ethiopia

Abstract This study lies in the simultaneous evaluation of maize hybrids for grain yield stability and FAW tolerance under natural infestation conditions in the Gamo lowlands, an area where such integrated assessments are limited. The study also provides valuable insights into th...

Soil organic carbon, texture and oxide-associated processes regulate phosphorus availability across Nigerian agroecosystems

Abstract Background and aims Phosphorus (P) limitation constrains productivity in tropical soils, yet the combined roles of soil organic carbon (SOC), texture, reactive minerals, and acidity in regulating plant-available P remain insufficiently quantified across diverse agricultu...
