Zinc (Zn) and iron (Fe) deficiencies are mostly found in salt affected soils in arid and semi-arid tracts of
India. To improve crop productivity in these soils, Zn and Fe sufficiency are to be ensured. Keeping in
view these constraints, the field experiment was conducted during 2013-14 and 2014-15 under pearl
millet-mustard cropping system to evaluate response of methods and application rates of Zn and Fe
fertilizer to mustard crop. The salt tolerant mustard (Brassica juncea) variety CS-54 was sown with 12
treatments of Zn and Fe i.e. T1- Control, T2- 5 kg Zn ha-1, T3- 6.25 kg Zn ha-1, T4- 7.5 kg Zn ha-1, T5- 7.5
kg Fe ha-1, T6- 10 kg Fe ha-1, T7- 12.5 kg Fe ha-1, T8- 5 kg Zn+10 kg Fe ha-1, T9- 5 kg Zn+10 kg Fe + 10 t
FYM ha-1, T10- Foliar sprays of 0.5% ZnSO4 (twice), T11- Foliar sprays of 1% FeSO4 (twice) and T12-
Combined foliar sprays (0.5% ZnSO4+1% FeSO4; twice) at 30 and 45 days after sowing of crops. The
results showed that the increase in levels of soil application of Zn from 0 to 7.5 and Fe from 0-12.5 kg ha-
1 increased seed yield of mustard. The maximum yield (22.7 q ha-1) was recorded under T9, which
received 5 kg Zn+10 kg Fe + 10 t FYM ha-1 followed by 5 kg Zn+10 kg Fe ha-1 ( with seed yield of 19.3 q
ha-1) over control. The positive correlation was recorded between seed yield and yield attributes with the
combined soil application of Zn and Fe with FYM or without FYM. Among the foliar application, highest
seed yield (17.2 q ha-1) was recorded under 0.5% ZnSO4+1% FeSO4 (T12) in mustard. Twice foliar
application of 0.5% ZnSO4+1% FeSO4 (T12) was equally effective in increasing the yield of mustard with
application of 5 kg Zn and 7.5 kg Fe ha-1 alone. The combined soil and foliar application of Zn and Fe
was found superior than sole soil and foliar application under saline environment. Significant build-up of
soil fertility in terms of available macronutrients (N,P & K) as well as micronutrients (Zn, Fe, Cu & Mn)
was observed with combined application of 5 kg Zn+10 kg Fe +10 t FYM ha-1 as compared to control or
sole application of respective nutrient. The results highlighted that combined use of Zn and Fe as soil and
foliar application is beneficial option for improving the mustard yield and soil fertility in terms of
available Zn and Fe in saline soils.
