The present investigation was carried out for assessment of seed hardening on morpho-physiological and yield parameters of mustard (Brassica juncea L.). For this purpose, twelve seed hardening treatments including control on mustard seeds variety (T-59) were used to study under filed conditions during Rabi, 2019-20 field experiment was laid out in Randomized Block Design (RBD) with three replications during Rabi 2019-20.Analysis for the data in field experiment revealed significance mean sum of squares due to seed hardening treatments for all the characters under study. The treatment were T0 - Control, T1 - Potassium nitrate (KNO3) 2% @12hrs, T2 - Zinc sulphate (ZnSO4) 2% @12hrs, T3 - Calcium chloride (CaCl2)2% @12hrs, T4 - Mono potassium phosphate (KH2PO4)2% @12hrs, T5 - Potassium chloride (KCl)2% @12hrs,T6 -Gibberellic acid (GA3)2% @12hrs, T7 - Indole Acetic Acid (IAA)2% @12hrs, T8 - Pungam leafextract2% @12hrs, T9 -Prosopsis leaf extract 2% @12hrs, T10 -Neem leaf extract5% @12hrs, T11 -Cow dung10% @12hrs, T12 -Panchagavya3% @12hrs.Maximum field emergence, leaf dry weight, leaf area was recorded in T3-Cacl2(2%) (12hrs). Minimum days to 50% flowering were recorded in T3. Maximum plant height at 30 DAS (cm), 60 DAS (cm) and 90DAS (cm) and Number of branches per plant was recorded in T3. Number of primary branches, number of secondary branches, number of silique per plant, number of seeds per siliqua, seed yield, test weight, biological yield and harvest index were also recorded high in T3 treatmentcacl2@2% followed by T6-GA3@2%.
