Abstract


A field experiment was conducted during kharif 2017 on medium deep black soil at the Main AgriculturalResearch Station, UAS, Dharwad to study the weed management in fodder maize. The study involved eight treatments,viz., T1: Atrazine 50 WP @ 1.25 kg a.i. ha-1 as pre emergence (PE), T2: Pendimethalin 30 EC @ 1.0 kg a.i. ha-1 (PE),T3: Oxyfluorfen 23.5 EC @ 0.15 kg a.i. ha-1 (PE), T4: Metribuzin 70 WP @ 0.25 kg a.i. ha-1 (PE), T5: Tank mixture of atrazine50 WP @ 0.5 kg a.i. ha-1 + pendimethalin 30 EC @ 0.75 kg a.i. ha-1 (PE), T6: Mixed cropping of maize at 60 kg ha-1 + cowpeaat 15 kg ha-1, T7: Weed free check and T8: Weedy check. Among weed management practices application of tank mixture ofatrazine 50 WP @ 0.5 kg a.i. ha-1 + pendimethalin 30 EC @ 0.75 kg a.i. ha-1 recorded higher plant height (246.3 cm), numberof leaves (12.6), leaf area (48.27 dm2 plant-1), total drymatter production (121.53 g plant-1) at harvest, higher green fodderyield (52.81 t ha-1), dry fodder yield (13.83 t ha-1), lower weed index (7.55 %), higher crude protein yield (1112.3 kg ha-1),higher gross returns (` 95,058 ha-1), net returns (` 57,915 ha-1) and BC ratio (2.57).
