Apply well decomposed cow dung@40 tonnes per acre in soil along with Nitrogen@50 kg, Phophorus@25 kg and Potash@25 kg in form of Urea@110 kg, Single Superphosphate@155 kg and Muriate of Potash@40 kg.
Apply whole quantity of cowdung, SSP and MOP and half quantity of Urea before transplanting.
Apply remaining quantity of Urea four week after transplanting as top dressing.
To get better flower (Curd) set and to obtain good yield, spray Water Soluble Fertilizer (19:19:19)@5-7 gm/Ltr water during the early plant growth.
40 days after transplanting take spray of 12:61:00@4-5 gram + email@example.com to 3 gram + Boron@1 gm per Ltr water.
To improve curd quality, apply Water Soluble Fertilizer 13:00:45@8-10 gm/Ltr of water at the time of curd development.
Do soil testing and if Magnesium deficiency is observed to overcome Mg deficiency apply Magnesium sulphate@5 gm/Ltr, 30-35 days after transplantation and for Calcium deficiency apply Calcium Nitrate@5 gm/Ltr, 30-35 days after transplanting.
If Hollow and sometimes discolored stems are observed, Also curds become brown and leaves may get roll and curl it is due to Boron deficiency, apply Borax@250 gm-400 gm/acre.
Plants have a uniform yellowish color, with leaves closest to the roots the root system very large oldest leaves will show purpling on underside first and margins of leaves tips will then turn purple followed by whole leaf taking on this color growth is retarded and plants have a poor root system.
Foliar spray of Urea 1% at fortnightly intervals
Pink color pigmentation seen in old leaves; stunted plant growth
Foliar spray of DAP 2% twice at fortnightly interval
Appears first on oldest cabbage leaves as spots shiny green leaves turn dull green, leaf margins turn a yellowish green followed by withering mature heads are loose and smaller.
In K-deficient cauliflower, leaf tips turn brown, leaves turn inward and can have a crinkled surface.
Foliar spray of K2SO4 1% twice at weekly intervals.
Symptoms appear first in youngest plant parts.
Tip burn with chlorotic young leaves.
Severe cases breakdown of the heart and dieback of rootlets.
Soil application of Gypsum 50 kg/ha.
Oldest leaves are affected first interveinal chlorosis with green veins leaf margins stay green at first, but ultimately dry up on cauliflower small chlorotic leaflets.
Poor rooting Magnesium deficiency should not be confused with virus infection.
Virus infection would be spotty in a field.
Foliar spray of MgSO4 2% twice at fortnightly interval.
Youngest leaves turned purplish, cupped upward leaf edges rolled in.
Soil application of Gypsum 50 kg/ha
Symptoms occur first on the youngest parts.
Youngest leaves turn chlorotic and their tips turn brown later on.
Trunk is hollow and when the top is cut off a brownish-colored cavity is found.
In B deficient cabbage, cavity is extended into the head.
The youngest leaves are chlorotic, leaf edges are scorched and blades turn downward develop poorly.
Soil application of borax @ 20 kg/ha or Foliar spray of borax 0.5% twice at fortnightly interval.
Youngest leaves become chlorotic.
Growth is stunted and heads are poorly formed.
The plant gives a wilted appearance.
Foliar spray of CuSO4 0.3% twice at fortnightly interval.
Poor growth interveinal chlorosis with dark green main veins of youngest leaves chlorosis extends into the leaf margins.
In severe cases the whole leaf turns yellowish.
Foliar spray of MnSO4 0.3% twice at fortnightly interval.
Cupping of the leaves and interveinal chlorosis followed by twisting and narrow elongation of leaves.
Poor curd development.
New leaves become irregular.
Soil application of 1.0 kg sodium molybdate /ha or Foliar spray of sodium molybdate 0.1% (Soil application of 120kg N, 75 kg P and Mo 1.5kg/ha, 1 kg B/ha).
Young leaves become small; curd color will be affected
