Weed dynamics and production potential of kharif maize (Zea mays L.) as influenced by new generation herbicides

Field experiment was carried out at AICRP on Weed Management Farm, Anand Agricultural University, Anand during kharif 2016 in sandy loam soil to study the effect of new generation herbicides on weed control and yield of kharif maize. The results indicated that application of atrazine 500 g/ha+pendimethalin 250 g/ha PE fb 2, 4-D 1000 g/ha LPoE provided effective control of monocot, dicot and total weeds as well as recorded higher grain yield (5.38 t/ha), net returns (Rs. 56300/ha) and B: C ratio (2.98) and it was followed by application of topramezone 25.2 + atrazine 500 EPoE fb IC + HW at 30 DAS, which recorded grain yield, net returns and B: C ratio of 5.11 t/ha, Rs. 47292/ha and 2.42, respectively.
