Response of tomato (Lycopersicon Esculentuni) grown in burnt paddy husk treated with palm oil mill effluent / Mohd Shafirun Mohd Azba

This experiment was conducted to determine the response of tomato variety MT 1 grown in burnt paddy husk treated with palm oil mill effluent (POME). This experiment was conducted to test the potentials of tomato variety MT 1 grown in burnt paddy husk. Another objectives are to determine the optimum growth rate of application of POME which would give the optimum level of tomato variety MT 1 grown in burnt paddy husk and to determine the optimum growth rate of the tomato variety MT 1 with the certain rates of POME application. This research was conducted by using Randomized Complete Block Design under a rain shelter structure with five treatment levels and 10 replications. The POME level per treatment was 0 g for control, 165 g for level, 330 g for level two, 495 g for level three and 660 g for level four which was equivalent to 0 kg per hectare, 50,000 kg per hectare, 100,000 kg per hectare, 150,000 kg per hectare and 200,000 kg per hectare respectively. From the observations and results in order to get an optimum yield, the application of single POME must be followed by the addition of fertilizer. Another important observation is the stage of decomposition of POME. If the POME is semi-decomposed, the phytotoxic problem caused by the phenolic acid produced by the microorganism activity affects plant growth. This problem also attracts an insect that decompose the POME. But the characteristics of the insect need further studies since it has not been identified yet. Besides, the growth rate of tomato in the agricultural wastes like burnt paddy husk compared to common soil needs further research.
