Abstract

Abstract
Objectives: Due to the ever-increasing world population it is impossible to find ways to reduce the interference of weeds with crops and thus increase crop yield. Also maintaining the long-term productivity of agricultural land requires sustainable food production which is achieved by strengthening and maintaining ecological processes in agricultural systems.

Materials and methods: The present experiment was conducted in the years 1401 and 1402 to determine the effect of cultivars and cover plants of rye and clover in controlling weeds, yield, and potato cultivars in the research farm of Mohaghegh Ardabili University as a split plot in 3 replications. The experimental treatments included the first factor of three different potato species (Agria, Jely, and Lady Rosetta) and the second factor of weed management (rye cover crop, Bersim clover, and testator (infested with weeds)(.

Results: The results of the analysis of variance showed that the main effect of cultivar the main effect of management and the reciprocal variable of two cultivars × management on weed density and dry weight, tuber size, and potato tuber weight were significant. The best weed management treatment was observed with the cultivation of Lady Rosetta variety with rye cover crops, and the worst weight was Acaria × no control (3.6 weight per square meter).

Conclusion: the use of desirable cultivars and cover plants of rye and clover can control potato weeds directly through the quick closing of the canopy to maintain vegetation on the surface until the end of the growing season.
