Abstract:
... Models provide a quantitative means to evaluate yield response of forage grasses to applied N and water availability. The objective of this analysis was to estimate model parameters (A, b, c) for bermu. dagrasses and bunchgrasses grown at the same location and during the same time period. The logistic equation was used to relate annual dry matter production to applied N for three bermudagrasses [C ...

Abstract:
... In northern areas where corn (Zea mays L.) is grown, no-till plants develop more slowly and, consequently, could be more susceptible to soil water limitations than plants under conventional tillage. This study was conducted to determine if removing in-row residues by pushing them into the interrow can solve problems related to no-till corn development in droughty soils. Residues were removed to pr ...
