Lime and Nutrients for Broccoli

Nutrient	Application Advice
Lime	Where necessary, apply lime to give an optimum pH of 6.5 - 6.8.
N	Depending on soil fertility, apply a base dressing of 70 – 100 kg/ha N. Top dressings can be applied up to 140 kg/ha.
P and K	Apply P and K rates as in the table below.
B	Use a boronated compound fertiliser or apply 2.25 kg/ha of boron.
FYM	If livestock manure is available, annual applications are very beneficial to both soil and crop but reduce the N, P and K application by 1.4 kg/ha, 1.2 kg/ha and 6 kg/ha respectively for each tonne/ha of well rotted and well stored FYM used (SI 31 of 2014).

Lime and Nutrients for Cabbage

Nutrient	Application Advice
Lime	Where necessary, apply lime to give an optimum pH of 6.5 - 6.8.
N	Spring cabbage Depending on soil fertility apply 0 – 50 kg/ha N as a base dressing. If the crop follows early potatoes, little or no N base dressing will be required. Heavy top-dressings are required in the January-February- March period. Apply 150 – 250 kg/ha N in one or two applications. Other cabbage Depending on soil fertility apply 100 – 150 kg/ha N as a base dressing. Top dressings can be applied up to 100 kg/ha.
P and K	Apply P and K rates as in the tables below.
B	Use a boronated compound fertiliser or apply 2.25 kg/ha of boron.
FYM	If livestock manure is available, annual applications are very beneficial to both soil and crop but reduce the N, P and K application by 1.4 kg/ha, 1.2 kg/ha and 6 kg/ha respectively for each tonne/ha of well rotted and well stored FYM used (SI 31 of 2014).

Lime and Nutrients for Summer and Autumn Cauliflower

Nutrient	Application Advice
Lime	Where necessary, apply lime to give an optimum pH of 6.5-6.8.
N	Depending on soil fertility, apply a base dressing of 0 – 120 kg/ha N. Top dressing are usually required – use up to 120 kg/ha as needed.
P and K	Apply the P and K rates as in the table below.
B	Use a boronated compound fertiliser or apply 2.25 kg/ha of boron.
Mo	Apply sodium molybdate (39% Mo) as a drench to the seed bed at the rate of 10 g in 15 litres of water per 10 m² of bed. Alternatively, apply 0.6 kg/ha of sodium molybdate as a field spray, which should not be mixed with other sprays.
FYM	If livestock manure is available, annual applications are beneficial to both soil and crop but reduce the N, P and K application by 1.4 kg/ha, 1.2 kg/ha and 6 kg/ha respectively for each tonne/ha of well rotted and well stored FYM used (SI 31 of 2014).
