Abstract
Nutrient mining ability of Wrinkle grass in transplanted naddy revealed that during season long competition wrinkle grass removed 74 kg N, 6 kg P and 108 kg K/ha as compared to 60 kg N, 5 kg P and 92 kg K/ha by paddy. Whereas under weed free situations paddy removed 174 kg N, 14 kg P and 238 kg K/ha. Weed free period for the first 40 to 70 days allowed no loss of nutrients. Nutrients uptake increased as the intensities of wrinkle grass increased from 20 to 140 plants/m2 and an intensity of 140 plants/m2 in paddy removed 63 kg N, 6 kg P aod 104kg K/ha. Anilofos (0.4 and 0.5 kg/ha), oxyfluorfen (0.3 and 0.5 kg/ha), piperophos (0.75 and 1.0 kg/ha). pendimethaJin (1.5 kg/ha) and oxadiazon (0.75 kg/ha) proved effective weed killer and allowed no loss of nutrients, whereas, butachlor (l.5 kg/ha) allowed 10. 1 and 13 kg/ha of N, P and K, respectively, by wrinkle grass.
