The study was accompanied to assess the effect of varying levels (0, 20, 40 or 60 t ha−1) of fly ash (FA) and nitrogen (N) (0, 60 or 80 kg ha−1) on Cd, Cr and Pb accumulation, antioxidant activity and yield traits of two mustard cultivars (Brassica juncea cv. ‘Varuna’ and ‘Pusa Bold’). The results showed that antioxidant activity increased concurrently as the FA levels increases. The dose of FA60 accompanied with N60 and N80 lowers enzymatic activity, photosynthetic pigments level, and yield; however, FA at the rate of 40 t ha−1 together with N60 significantly enhanced the crop productivity followed by N80. These results suggest that FA40N60 proved optimal for enhancing crop growth and yield, whereas a high concentration of FA (FA60) caused oxidative stress in both mustard cultivars. Oleic and linoleic acid contents were increased; however, erucic acid content decreased by the application of FA40N60.

用粉煤灰和无机氮肥在土壤改良剂上生长的芥菜(Brassica juncea L.)的金属积累,抗氧化活性,生长和产量属性

该研究是伴随着以评估不同水平的影响(0,20,40或60吨公顷-1)飞灰(FA)和氮(N)(0,60或80公斤公顷-1上镉,铬)和两个芥菜品种(芥菜品种“ Varuna”和“ Pusa Bold”)的铅,铅积累,抗氧化活性和产量性状。结果表明,随着FA含量的增加,抗氧化活性同时增加。FA 60配以N 60和N 80的剂量降低了酶活性,光合色素水平和产量。但是,FA以40 t ha -1的速率与N 60一起显着提高了农作物的生产力,随后是N 80。这些结果表明,FA 40 N 60被证明是增强作物生长和产量的最佳选择,而高浓度的FA(FA 60)则在两个芥菜品种中均引起氧化应激。油酸和亚油酸含量增加;然而,芥酸含量通过使用FA 40 N 60降低
