Abstract:

There is lack of information on the effects of rice residue position and load on the growth and development of Phalaris minor Retz. and the efficacy of different herbicides in wheat under different rice residue management situations. The studies revealed that surface application of rice residues @ 6 and 7 t/ha significantly reduced the growth and development of P. minor and recorded higher weed control efficiency as compared to incorporation and no rice residue treatments. Application of rice residues @ 6 and 7 t/ha also significantly reduced the emergence of wheat seedlings as compared to rice residue incorporation and no rice residue treatments.  Wheat growth parameters, yield attributes, grain and biological yield were statistically at par in all the rice residue management techniques. Application of clodinafop 60 g/ha, sulfosulfuron 25 g/ha and mesosulfuron + iodosulfuron 14.4 g/ha significantly reduced the growth and development of P. minor and registered higher weed control efficiency as compared to unweeded control. Consequently, all the herbicidal treatments recorded significantly higher wheat growth parameters, yield attributes, grain and biological yield as compared to unweeded control treatment.
