Tomato Growing Requirements
Tomatoes give good results when grown in well managed sandy loams and heavy clay loam free of hard pan.
Best results are obtained in deep, well drained loams. The soil should be rich in organic matter and plant nutrients, with a pH value of 6 to7
Propagation of Tomatoes
Tomatoes are best brought up using seeds.
However you can also use cuttings from mature plants to get more seedlings
You can Broadcast the seeds on the raised bed and lightly cover with soil.
Or else you can create shallow lines using your finger and place the seeds there, then cover with little soil.
In one acre, you plant over 8000 plants with a spacing of 2*2ft.
Seedlings are usually ready for transplanting 2-3weeks after sowing, and they must be transplanted on moist soil.
At transplanting you may use a fertilizer like DAP, place a few granules in the hole, Cover with some soil, then plant your seedling.
Of you can use farm yard manure, you apply 2hand fulls in each hole, mix it with soil and transplant.
Fertilization: Tomatoes are heavy feeders of plant nutrients including nitrogen, phosphorus and potassium. The plant responds well to organic fertilizers too.
After 1 month from planting, you have to start applying folliar fertilizers like Vegimax to boost the growth of the crop.
Weed control; these can be controlled chemically or mechanically. Alternatively hand hoes can be used to shallowly plough off the weeds.
Avoid using herbicides when the plants are already in the field
Pruning; this practice influences the flowering and fruiting of tomato plants. Prune plants by pinching off lateral branches as they appear in the leaf axils.
The more you reduce excess leaves and branches, the more space you leave for the plant to use nutrients for fruit development.
Mulching; Mulch newly planted tomatoes in order to retain moisture in the soil and avoid weeds from growing.
