A field experiment was conducted at IFS farm, Main Agricultural Research Station (MARS), Raichur on deep black soil during kharif, 2014 to study chemical weed management in baby corn (Zea mays L.). The results revealed that among herbicidal treatments, pre-emergence application of atrazine 50 WP @ 0.5 kg a.i. ha-1 + pendimethalin 38.7 CS @ 0.5 kg a.i ha-1 recorded significantly lower weed density (6.34 / 0.5 m2) and weed dry weight (1.21g / 0.5 m2), lower weed index (7.65%) and higher weed control efficiency and it was on par with atrazine 50 WP @ 1.0 kg a.i. ha-1 as pre-emergence application fb 2, 4-D Sodium salt 80 WP @ 1.0 kg a.i. ha-1 as post-emergence application at 25 DAS at harvest. Among the weed management treatments, weed free check recorded significantly higher uptake of nutrients (191.53, 56.57 and 112.89 NPK kg ha-1) and was on par with atrazine 50 WP @ 0.5 kg a.i. ha-1 + pendimethalin 38.7 CS @ 0.5 kg a.i ha-1 as pre-emergence application. With regard to the yield and economics, pre-emergence application of atrazine 50 WP @ 0.5 kg a.i. ha-1 + pendimethalin 38.7 CS @ 0.5 kg a.i ha-1 gave significantly higher green cob yield (10.98 t ha-1), green stalk yield (28.83 t ha-1) and higher gross returns (Rs. 1,93,497), net returns (Rs. 1,49,963) and BC ratio (4.44).
