Effect of intercropping of cabbage, lettuce, parsley and chard on weed incidence and cabbage yield
The present study aimed to evaluate the effect of the association of cabbage, lettuce, parsley and chard on the incidence of weeds and cabbage yield parameters. The research was conducted on the Facultad de Ciencias Agrarias campus of the Universidad de Concepción, Paraguay. The treatments consisted of cabbage (T1), cabbage+lettuce (T2), cabbage+chard (T3), and cabbage+parsley (T4). The trial was laid out in Randomized Complete Block Design (RCBD) with four treatments and six replications, totaling 24 Experimental Units (EUs). Measurements included the percentage of weed incidence, cabbage yield (ton ha-1), and equatorial and polar diameter of the head (cm). These mean values were subjected to analysis of variance (ANOVA) and when significant differences were found between treatments, the mean comparison was performed using the Tukey test at 5%. No significant differences were recorded for cabbage yield, equatorial, and polar diameter (P>0.05). It is concluded that the plant species used in this research in consortium with cabbage positively influenced reducing weed incidence and increasing cabbage yield, but did not significantly affect the equatorial and polar diameters of cabbage heads.
