Abstract:
A field experiment was conducted during kharif season 2019 at Kolhapur (Maharashtra) to study the integrated weed management in kharif sweet corn. Atrazine and Pendimethalin as pre-emergence, while 2, 4-D and Topramezone as post-emergence were tested alone and in integration with hand weeding and interculturing. The results revealed that the treatments weed free check was recorded lowest weed intensity. However among all the integrated weed management methods weed free check was recorded minimum weed population. weed free check was found to be recorded significantly maximum growth, yield and quality attributes viz., plant height, no. of functional leaves plant-1, leaf area, Dry matter plant-1, green cob yield and green fodder yield and found most effective to control weeds in sweet corn and recorded lowest weed dry matter, weed index and highest weed control efficiency which is at par with treatments pre-emergence application of pendimethalin @ 1 Kg a.i. ha-1 + 1 hand weeding at 30 DAS and Pre emergence application of atrazine @ 1 kg a.i ha-1 + 2,4-D Sodium salt @ 0.5 kg a.i ha-1 at 30 DAS found remunerative, therefore, these integrated weed management practices could become effective and economical under sub mountain agro-climatic conditions of Maharashtra.
