摘要: No tillage (NT) has an advantage over conventional tillage (CT) in hilly lands of the Appalachian region of the Eastern US because it reduces soil erosion and lowers energy input. Field experiments were conducted for three years (at an elevation of 908 m) to evaluate the effects of tillage (CT, NT) and P rates (25, 200 kg P ha-1) on shoot and root growth and nutrient uptake by silage corn (Zea mays L.). Shoot dry matter yields, root length per plant, and root density in NT were significantly higher than in CT. In both tillage …
