A field experiment on “Integrated weed management with low volume herbicides on growth and yield of sweet corn (Zea mays var. saccharata)” was undertaken during kharif, 2013-14 at Post Graduate Institute Instructional Farm, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar (Maharashtra). The various growth contributing characters viz., plant height, number of leaves, leaf area of plant and dry matter production plant-1 were significantly higher with treatment weed free check which were at par with PE application Sulfosulfuron + imazethapyr (@ 15+25 g a.i. ha-1) with one HW at 40 DAS. The yield contributing characters viz., number of cobs plant-1, length of cob, diameter of cob with husk and without husk, were recorded significantly higher with treatment weed free check being at par with PE application of sulfosulfuron + imazethapyr (@ 15+25 g a.i. ha-1) with one HW at 40 DAS. The green cob and green fodder yields were significantly higher in treatment weed free check which was at par with PE application of Sulfosulfuron + Imazethapyr (@ 15+25 g a.i. ha-1) with one HW at 40 (T6) followed by treatment PE application of Sulfosulfuron + Imazethapyr (@ 15+25 g a.i. ha-1) (T3). Weed free check recorded cent per cent and significantly higher weed control efficiency and minimum weed index than rest of the treatments. Among the herbicidal weed management treatments, treatment PE application of Sulfosulfuron + Imazethapyr (@ 15 + 25 g a.i. ha-1) with one HW at 40 DAS (T6) registered significantly higher weed control efficiency over other treatments at all the stages of observations.
