Groundnut  In calcareous soils, apply 50 kg Ferrous sulphate per ha as
basal dose or three foliar sprays of 1% FeSO 4.
or
 Apply 575 kg of Ferro-gypsum per ha as basal application.
Soybean  In calcareous upland soils, 2-3 times foliar spray of 2%
ferrous sulphate+0.1% citric acid is recommended.
 In soybean grown in medium black and black-red mixed
soils, apply 40 kg Ferrous sulphate per ha as basal dose OR
two foliar sprays of 1-2% FeSO 4.
Soybean-Wheat  In medium black soils, apply 50 kg Ferrous sulphate per ha

as basal dose and foliar sprays of 1-2% FeSO 4.
Rice  Yellowing of rice leaves due to iron deficiency can be
effectively controlled by 3 foliar applications of 1.0% FeSO 4
at weekly interval. It should be followed after irrigation.
 Green manuring with dhaincha is also recommended to
amend iron deficiency in rice.
Rice nursery  Once yellowing of seedlings or necrosis of leaf tips are
noticed in rice nursery, 2-3 foliar applications of 1.0% FeSO 4
at weekly interval can be done to supplement the iron
deficiency.
Bengal gram  In medium black and black-red mixed soils, apply 50 kg
Ferrous sulphate per ha as basal dose and give two foliar
sprays of 1-2% FeSO 4.
Pigeonpea  In light textured soils, provide foliar spray of 0.5% FeSO 4at
60, 90 and 120 days after sowing.
Mustard  In light textured soils, apply 15 kg FeSO 4 per ha at the time
of sowing, followed by two foliar sprays of 1% FeSO 4.
Sesame  In medium black calcareous soils, apply 40 kg Ferrous
sulphate per ha as basal dose.
Jowar  In black and red loamy soils, apply 25-50 kg Ferrous
sulphate per ha as basal dose in alternate year.
Bhindi  In light textured soils, apply foliar spray of 0.5% FeSO 4at 15,
30, 45 and 60 days after sowing.
Potato  Apply foliar spray of 0.5% FeSO 4at 40, 50 and 60 days after
sowing in light textured soils.
Tomato  In light sandy soils, foliar spray of 0.5-1.0% FeSO 4at 30, 50
and 70 days after transplanting is recommended.
Sugarcane  Foliar spray of 5.0 gram FeSO4 + 2-3-gram citric acid per
liter water can be made for 2-3 times during early growth
stage of sugarcane.
or
 Apply 50 kg Ferrous sulphate per ha as basal dose.
 In sugarcane grown on silty loam soils, apply 100 kg Ferrous
sulphate per ha as basal dose. This is sufficient for main as
well as ratoon crops.
