Abstract
Parthenium hysterophorus, an invasive weed, is outcompeting native species like Cannabis sativa in Khyber Pakhtunkhwa, Pakistan. An experiment was conducted at Bacha Khan University's Department of Agriculture laboratory in Charsadda, KPK, Pakistan. Parthenium hysterophorus and Cannabis sativa plants were collected from a local field in Sakhakot, Malakand, Khyber Pakhtunkhwa. The experiment followed a completely randomized design (CRD) with two replications per pot. Plants were subjected to five salt levels (standard, 3g, 6g, 9g, and 12g) and the parameters studied included plant height, leaf area, number of branches, root weight, and plant weight. Statistical analysis was performed using Complete Block Design (CBD) and Analysis of Variance (ANOVA) (STATISTIX 8.1). The study aimed to investigate the impact of salinity levels on the growth and development of two competitive weeds, Parthenium hysterophorus and Cannabis sativa. Results showed that increasing salt levels significantly reduced growth, affecting plant height, shoot and root weight, and leaf area. These findings suggest that salinity can be a potential tool for managing Parthenium spread. Further research is needed to confirm these results under different ecological conditions.
