Other claims from this paper (6)
- Observation DAP microdosing achieved 86% of grain yield under broadcast NPK.
- Observation NPK microdosing achieved 79% of grain yield under broadcast NPK.
- Intervention effect Fertilizer microdosing significantly increased early millet leaf area index and leaf chlorophyll content.
- Intervention effect Microdosing increased topsoil lateral root length density by 40% at 50 cm from the hill center relative to broadcast NPK.
- Observation Fertilizer microdosing did not significantly change soil pH in the root zone.
- Mechanism The authors attribute higher millet yield under microdosing to early lateral root proliferation and better soil nutrient exploitation.
