5 – 10kg of seeds/ha
Nursery Practices for tomato cultivation
(i) It is done on ground, beds or seed boxes/trays with top soil, thoroughly mixed and watered.

Spacing for tomato planting
(i) 60cm x 60cm without staking
(ii) 50cm x 30cm with staking.

(i) Weeding: This should be done at regular intervals.
(ii) Watering: Soon after transplanting, seedlings should be watered every morning and evening till the plants are able to stand on their own.
(iii) Fertilizer Application: Apply N.P.K 15:15:15 fertilizer to each plant three weeks after transplanting at 250kg/hectare, or apply any organic manure like compost or farmyard manure at 30-40 metric tonnes per hectare.
(iv) Staking: Provide stakes to enable plants to stand erect and prevent lodging. Stems are tied or trained to the stakes. Staking allows for good fruiting and keeps fruits from disease attack. Arising from contact with soil. Staking should be done before flowering.

It is a fungal disease (Fusarium oxysporium) which is spread by wind.
Symptoms
These include the gradual dropping of leaves followed by wilting and drying up of leaves of the whole plant.
Control
(i) Treat soil with copper fungicide
(ii) Practice crop rotation
Root-knot disease
: It is caused by a nematode. Roots develop galls or knots with yellow, curled leaves and dwarf plants.
Control
(i) Treat soil with nematicide
(ii) Plant resistant varieties
(iii) Practice crop rotation
Bacterial wilt
: This is caused by a bacterium called Pseudomona solaraceurium. It is transmitted through the soil and it attacks roots.
Symptoms
Symptoms include wilting of the leaf, death of the affected plant, and slimy exudation from the stem
Control
(i) Practice crop rotation
(ii) Avoid infected soil
Leaf spot disease
: This disease is caused by a fungus called Chadosporium spp. It is an air-borne disease whose spores are deposited on leaves.
