An experiment was conducted at the Horticulture Farm of Bangladesh Agricultural University, Mymensingh during the period from October 2003 to March 2004 to evaluate the effect of organic and inorganic fertilizers on the production of tomato. The experiment consisted of five different treatments viz, cow dung, poultry manure, mustard oil cake, inorganic fertilizer, and inorganic + organic fertilizer. Different treatments showed significant variations on yield components and yield of tomato. Poultry manure treatment gave the best results on all the parameters except, fruit length, fruit diameter and weight of individual fruit. The highest number of leaves, number of flower clusters, total number of flowers and fruits plant-1, number of flowers cluster-' and yield of tomato (89.6 t ha-1) were obtained from poultry manure treatment. On the contrary, the lowest values of all these parameters and yield (68.8 t ha-1) were recoded from cow dung treatment. The highest fruit length (5.44 cm), fruit diameter (5.56 cm) and individual fruit weight (90.7 g) were recorded from the inorganic treatments. The highest gross income (Tk. 716640 ha-1), net return (Tk. 658837 ha-1) and benefit cost ratio -(12.4) were recorded from the poultry manure treatment. The performance of organic and inorganic fertilizers on tomato production followed the pattern as poultry manure > mustard oil cake > inorganic fertilizer > inorganic + organic fertilizer > cow dung.

Variety and Species
i) to study the effect of cow dung, poultry manure and mustard oil cake on the growth and yield of tomato; ii) to identify the suitable organic manure which would be better for tomato cultivation, and iii) to compare the growth and yield of tomato raised through use of organic and inorganic fertilizer.
The experiment was carried out at the Horticulture Farm of Bangladesh Agricultural University, Mymensingh, during the period from October 2003 to March 2004. The soil of the experimental field was silty loam with the pH of 6.7. The analytical data of the soil have been presented in Table 1. The tomato cultivar used in the experiment was BARI Tomato-2 (Ratan). The experiment consisted of five treatments viz: 11= Cow dung (15 t ha-1), T2 = Poultry manure (10 t ha 1), T3 = Mustard oil cake (5 t ha-1), T4 = Inorganic fertilizer (550 kg urea ha-1 + 450 kg TSP ha-1 + 250 kg MoP ha-1) and T5 = Inorganic + organic fertilizer (550 kg urea ha-1 + 450 kg TSP ha-1 + 250 kg MoP ha-1 + 15 t cow dung ha-').The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Thirty day old seedlings were transplanted on 20 November during the Rabi season of 2003. Intercultural operations such as gap filling, weeding, staking, pruning, irrigation, and plant protection measures were taken as and when necessary. The collected data were analyzed and the differences between the means were evaluated by the least significant difference (LSD) test at 5% level of probability.
The findings of the experiment indicated that the best yield and the highest financial benefit could be obtained from poultry manure treatment. So, it may be concluded that comparatively better tomato production in possible by using poultry manure rather than using other organic and inorganic fertilizers.
