Abstract

Influence of fat hen (Chenopodium album) and barnyard grass (Echinochloa crus-galli) density on potato yield.

Abstract

Influences of different intensities of weeding of fat hen and barnyard grass on potato yield were evaluated during 1986-90. Fat hen at a density of 2-4 plants/10 m2 significantly decreased (12%) tuber yield. Competition by barnyard grass was lower, with significant decreases (11%) in tuber yield observed at 4-8 barnyard grass plants/10 m2.
