The response of nipping on morpho-physiological parameters and yield of twenty two genotypes of Indian mustard [Brassica juncea(L.) Czern&Coss.] was studied in a field experiment. The results revealed that nipping significantly increased plant height, dry matters accumulation, number of primary and secondary branches per plant, number of sillquae per plant, seed yield ( kg ha-1 ), harvest index () over nonnipping. respectively. | Effect of nipping on growth assimilate supply and yield of Indian mustard genotypes
