The correct answer is 6 - 7. Tomato (Lycopersicon esculentum) is an annual or short lived perennial pubescent herb. Tomato can be grown on a wide range of soils from sandy to heavy clay. Well-drained, sandy or red loam soils rich in organic matter with a pH range of 6 - 7 are considered as ideal. Seeds are sown in June July for autumn winter crop and for spring summer crop seeds are sown in November. In the hills seed is sown in March April.
