Allelopathic Impact of Parthenium hysterophorous Leaf Extract on the Yield-Contributing Traits of Allium sativum L.

Allelopathic Impact

Abstract

Allelopathy is a biological phenomenon by which plants release biochemical compounds (allelochemicals) into their surroundings, manipulating the progress and existence of other organisms. The current work aimed to investigate the allelopathic influence of Parthenium hystyerophrous extract on garlic genotype. The attentiveness of Parthenium extract was applied to the seedling of garlic, and found maximum plant height (82.00cm) for treatment (T3), while minimum was noted in T1 treatment (24.50). the study investigated the effect of treatments on root length and dry matter reduction. The results showed a significant reduction in root length, averaging 3.50, while it had a minimum reduction at 3.65. Statistical analysis revealed varying correlations between root size and dehydration depth, with R values of 0.767, 0.173, and 0.041. The relationship between treated and control plant root lengths was significant in control and treatment-1, but less so in treatment-3. Although the correlation between weight and root length was significant in control and treatment-1, it was weaker in treatment-3, with an R value of 0.138 and 0.31, respectively. This study aimed to explore various applications of allelopathy, suggesting that effective allelochemicals should be further isolated and investigated.
