Yield and Yield Components of Lallemantia (Lallemantia iberica Fisch. et Mey) intercropped with Anise (Pimpinella anisum L.) under Weed Infestation

Abstract

Medicinal plants are used for human health and creating diversity in agricultural ecosystems and have impact on the weed control. In this context, an experiment in order to evaluate the yield and yield components of lallemantia in intercropping with anise was carried out. The research was conducted as factorial experiment based on randomized complete block design. The first factor was weed control (Free of weeds and weed infested) and the second factor included three levels of intercropping as slight increase in the direction lallemantia with ratios of 20% lallemantia and anise favorable density ,40% lallemantia and anise favorable density and 60% lallemantia and anise favorable density and monocropping of both species. The results showed that planting pattern effect on weed dry weight was significant at the 5% level. Also intercropping 20: 100 (lallemantia – anise) and Free of the weed was the most suitable treatment. The highest grain yield in monocropping under weed Free condition was obtained. In all intercropping, LER and RVT were higher than both monocropping. It should be noted that the lallemantia even with weedy condition could produce yield economically.
