Management of Phalaris minor in Wheat through Integrated Approach

Abstract

A field experiment was conducted at experimental farm of Punjab Agricultural University, Ludhiana during 1999–2000 and 2000–01 crop season to study the effect of agronomic manipulations on Phalaris minor. The studies envisaged that the wheat crop grown under deep tillage system done with mould board plough had 13.7 and 40% less population and dry maller of Phalaris minor, respectively and thus gave 18.2% higher grain yield over zero tillage system. Closer row spacing of 15 cm resulted in less plant population and dry maller of P. minor and gave 8% more grain yield as compared to normal spacing of 22.5 cm because of better canopy coverage over the weeds. Further, the application of clodinafop (60 g ha−1) reduced the population and dry maller accumulation of P. minor by 92.5 and 90.6%, respectively, and hence resulted 53.9% higher grain yield over unweeded check due to selective kill of this weed.
