WEEDS

This study investigated the influence of soil pH variation on weed development originating from soil seed banks. Soil samples were subjected to distinct pH concentrations of 3, 5, 7, 9, and 11. The objective was to ascertain the effects of varying pH levels on weed species' development and diversity, thereby shedding light on potential implications for crop productivity. The study's significance lies in its exploration of the relationship between pH concentrations and weed diversity, with implications for crop management. If weeds, which possess adaptable traits, are compromised by pH fluctuations, the security of agricultural crops faces a similar threat. The experiment entailed exposing soil samples to diverse pH concentrations, with two sets of replicates and a control group. Initially, the samples were
irrigated with a 300 ml solution, followed by subsequent applications of 200 ml every alternate day. Emergent weed counts were documented at four-day intervals over an 8-week period. The findings revealed noteworthy trends. At pH extremes of 3 and 11, reduced diversity was observed due to growth suppression, indicating the susceptibility of weed species to extreme pH conditions
