ABSTRACT Aim: Laboratory experiments were carried out at Trinity Anglican School, Australia in 2010 to study the effect of various organic and inorganic fertilisers on the growth of tomato plants in the northern tropical region of Queensland, Australia during the winter season of 2010. Five pots with tomato seedlings were prepared for the experiment. Two pots were fertilised with inorganic fertilisers (IF), two with organic fertilisers (OF) and one without any fertilisers. All pots were watered daily. Each week height, number of leaves, flowers and fruits were recorded on all pots. At the end of experiment, the heighest height was recorded with Powerfeed (OF) and maximum number of leaves with Seaweed (OF). Flowers started to appear in week six followed by fruit in week seven. Number of flowers and fruit were highest with Herb (IF). Plant with no fertiliser had minimum growth and late appearing flowering and fruits. From this experiment it is clear that fertilisers play an important in role of Tomato plants growth. Vegetative phase was longer with OF while fruits and flowers were earlier with IF.

HYPOTHESIS: I believe that the tomato plants grown with organic fertilisers will have a good growth compared to the plants grown with inorganic fertiliser and no added fertiliser.

INTRODUCTION The tomato is an herbaceous perennial plant, but is usually grown as an annual in temperate regions since it is killed by the frost. Tomato plants can be grown in fairly wide range of soil and climatic conditions, and they are also suitable for container growing. Tomato is one of the world's most important vegetable crops. (Scholberg, J et al 2000)

Growth characteristics of tomato plants are governed by genetic traits, management practices, nitrogen content of soil and fertilisers, location and season, method of irrigation(sub and drip irrigation), type of fertilisers(organic or inorganic), salinization of soil and minerals. Some minerals are required by the plants for the normal development and growth stages which are met by foliar (e.g. leaf) absorption or by the uptake of solutes from the soil solution. The three primary macronutrients are nitrogen (N), phosphorus (P), and potassium (K). The three secondary macronutrients are calcium (Ca), sulphur (S), magnesium (Mg) and the micronutrients or trace minerals are boron (B), chlorine (Cl), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu), molybdenum (Mo) and selenium (Se).

The growers of vegetable crops mainly add nutrients to plant roots zones at levels exceeding many times of those required for optimal growth because of the uptake of solutes from the soil solution and soil matrix. (Mawgoud A.M.R et al 2007). Groundwater for irrigation used by the growers must consider the amount of nitrogen in the water when deciding how much nitrogen fertiliser they should apply to crop as...
