Efficacy of different chemical and non chemical approaches for management of Broomrape in Indian Mustard

Abstract

Indian mustard (Brassica juncea) is infested with a parasitic weed, Egyptian broomrape (Phelipancheaegyptiaca), threatening its production in south-western parts ofHaryana. Afield experiment was conducted to study the effect of broomrape control treatments on the growth rate, number of days to 50% flowering and siliqua initiation, primary branches, secondary branches and grain yield of Indian mustard. The crop growth rate, number of primary and secondary branches and the grain yield were higher when supplied with 125% of recommended fertilizer (N & P) + foliar spray of glyphosate at 25 and 50 g/ha + 1.0% solution of (NH4)2SO4 at 25 and 55 DAS, respectively. This was followed by foliar spray of glyphosate at 25 and 50 g/ha + 1.0% (NH4)2SO4 at 25 and 55 DAS, respectively. The broomrape control treatments had no significant effect the relative growth rate and number of days to 50% flowering.
