Dynamics of size structures : simulation and experiments in seedling stands of Pseudotsuga menziesii and Fraxinus mandshurica

Creator:

Petersen, Terry D.

Abstract:

Computer simulations and experiments were used to determine the basis for skewness and inequality in size structures (frequency distributions of Individual plant sizes) prior to self-thinning mortality. In simulated stands, density-dependent neighborhood heterogeneity caused variability in the growth rate of individuals with the same size, and such variability caused skewness...

An evaluation of weed interference in rice grown on hydromorphic soils in West Africa

Creator:

Diop, Amadou Makhtar

Abstract:

Field, screenhouse, and laboratory experiments were conducted to study weed interference in rice grown on hydromorphic soils at the International Institute of Tropical Agriculture (IITA) at Ibadan, Nigeria. Rice and weeds emerged at the same time, 1 week after planting. Weed dry weight was significantly reduced when the crop was...
