dc.description.abstract | The interaction between salinity (8 and 12 dS m–1) and three levels (40, 80 and 120 kg ha¯1) of different forms of nitrogen (NO3¯, NH4+ and NO3– + NH4+) were studied in Brassica juncea cv. RH-30. The plants were salinized with 8 and 12 dS m–1 at 35 and 55 days after sowing. The relative water content (RWC), water potential (ψw) and osmotic potential (ψs) exhibited a marked decline under salinity stress. The application of the combined form (NO3¯ + NH4 +) of nitrogen (120 kg ha¯1) considerably improved the water status and mitigated the adverse effect of salinity on growth. The salinity-induced osmotic effect led to stomatal closure and caused a substantial reduction in net photosynthetic rate (PN), stomatal conductance (gs) and transpiration rate (E) at the pre-flowering and flowering stages (45 and 65 DAS). Salinity effects were considerably moderated by additional nitrogen supply, which varied with the source of nitrogen, the level of salinity/fertilizer and the stage of plant growth. The inhibition in photosynthesis was relatively greater in ammonium-fed (NH4+) than in nitrate-fed (NO3¯) plants, while the transpiration rate was relatively lower in nitrate-fed plants grown either with or without saline water irrigation. The nitrate form of nitrogen @ 120 kg ha–1 proved best in alleviating the adverse effect of salinity on photosynthesis and transpiration at both the growth stages. | en_US |
