A study was conducted in the spring season of 2017 in sweet corn crop to evaluate different weed management practices with different combinations of cultural, manual methods with some recommended and new generation herbicides to find the best management practice with lowest impact upon soil health. Effectiveness of weed control measures were evaluated on the basis of total weed dry matter accumulation and weed control efficiency. Pre-emergence application of atrazine 1000 g/ha which is a generally practiced weed management measure was found to have detrimental effects upon soil micro flora as indicated from the decline in soil dehydrogenase activity. The study also indicated about the time that a healthy soil needs to recover from the damage caused to the soil micro flora by application of different chemicals.
