Abstract:
A field experiment was conducted on medium black calcareous soil at Junagadh (Gujarat) during Rabi season of 2019-20 to study the bioefficacy of herbicides and their mixtures for weed management in Rabi maize (Zea mays L.). The experiment was laid out in randomized block design with three replications. The treatments comprised of: Atrazine 500 g/ha as PE fb 2,4-D (SS) 500 g/ha as PoE at 30 DAS, Atrazine 500 g/ha as PE fb halosulfuron-methyl 60 g/ha PoE at 30 DAS, Atrazine 500 g/ha as PE fb tembotrione 100 g/ha as PoE at 30 DAS, Atrazine 500 g/ha as PE fb topramezone 25 g/ha as PoE at 30 DAS, Atrazine 500 g/ha as PE fb tank-mix halosulfuron 30 g/ha + 2,4-D (SS) 250 g/ha at 30 DAS, Atrazine 500 g/ha as PE fb tank-mix halosulfuron 30 g/ha + tembotrione 50 g/ha at 30 DAS, Atrazine 500 g/ha as PE fb tank-mix halosulfuron 30 g/ha + topramezone 12.5 g/ha at 30 DAS, HW at 15 and 30 DAS, Weed free check and Unweeded check. The results of the experiment indicated that application of atrazine 500 g/ha as PE fb tembotrione 100 g/ha as PoE at 30 DAS, atrazine 500 g/ha as PE fb topramezone 25 g/ha as PoE at 30 DAS and HW at 15 and 30 DAS improved growth and yield attributes, suppressed weed growth, and ultimately recorded higher grain and dry fodder yields of maize along with higher net returns.
