Abstract/ Executive Summary:

The field experiment was conducted at the Horticultural farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka -1207 during the period from October 2014 to March 2015 to find out the efficacy of different organic manures and different varieties on the growth, yield performance of organically grown tomato. The experiment comprised of two different factors: Factor A. four types of organic manure [M₀= Control (No organic manures application), M₁ = Cow dung (30 t.ha^-1), M₂ = Poultry manure (25 t.ha^-1) and M₃ = Vermicompost (20 t.ha^-1)] Factor B. three types of variety V₁ = BARI tomato 15, V₂ = BARI tomato 14 and V₃ = BARI tomato 2. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Encouraging responses were monitored in all respects. Among the treatment combination M₂V₁ (Poultry manure + BARI Tomato 15) showed the highest plant height, maximum number of the flower clusters, number of flowers per cluster, number of fruits per cluster, and number of fruit per plant with improved fruit size. The maximum yield (86.25 t/ha) was recorded from the treatment combination of M₂V₁ (Poultry manure + BARI Tomato 15), while the treatment combination of M₀V₃ (Control treatment + BARI Tomato 2) gave the minimum yield (31.25 t/ha). Therefore, BARI Tomato 15 coupled with poultry manure can be the most suitable for enhanced yield and can be considered a noble practice in sustainable agriculture.

Commodity: Organic fertilizer, Tomato

Objectives:

To identify the suitable tomato variety and the efficacy of different organic manures which can promote growth, increase the yield of tomato in a sustainable and environment-friendly way.

Methodology:

The experiment was conducted at the Horticultural farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh from October 2015 to February 2016. The location of the experimental site was 23º74^/N latitude and 90º35^/E longitude and at an elevation of 8.2 m from sea level. The climate of the experimental site was under the subtropical climate, characterized by three distinct seasons, the winter season from October to February and the pre-monsoon or hot season from March to April, and the monsoon period from May to October. The soil of the experimental area belongs to the Modhupur Tract (AEZ No 28). It had shallow red-brown terrace soil. The selected plot was medium high land and the soil series was Tejgaon. Three varieties of tomato were used in this experiment viz, V₁ = BARI tomato 15, V₂ = BARI tomato 14, and V₃ = BARI tomato 2.Tomato seeds were collected from Vegetable division, Horticulture Research Centre (HRC), Bangladesh Agricultural Research Institute (BARI), Gazipur, Bangladesh. The experiment was laid out in Randomized Complete Block Design with three replications. There were altogether 12 (4 x 3) treatment combinations used in each block were as follows; M₀V₁, M₁V₂, M₂V₃, M₀V₂, M₁V₃, M₃V₁, M₀V₃, M₂V₁, M₃V₂, M₁V₁, M₂V₂, M₃V3. The experimental plot was first divided into three blocks. Each block consisted of 12 plots. Thus, the total numbers of the plot were 36. Different combinations of treatments were assigned to each plot as per the design of the experiment. The size of a unit plot was 2.4 m ×2.4 m. A distance of 0.5 m between the plots and 1.0 m between the blocks was kept. The experimental land area was prepared by several ploughing and cross ploughing with a power tiller followed by laddering to bring about a good tilth. The land was leveled, corners were shaped and the clods were broken into pieces. The weeds, crop residues, and stables were removed from the field. Total organic manures were applied according to their treatment and finally leveled. Thirty days-old healthy seedlings were transplanted at the spacing of 60 cm × 40 cm in the experimental plots. Thus the 24 plants were accommodated in each unit plot. Five plants were randomly selected from each unit plot for the collection of data. The plants in the outer rows and the extreme end of the middle rows were excluded from the random selection to avoid the border effect. The height of the plants was measured from the ground level to the tip of the highest leaves. The data obtained for different parameters were statistically analyzed to find out the significant difference of variety and different manure applications on yield and yield contributing characters of tomato. The mean values of all the characters were calculated and the analysis of variance was performed by the ‘F’ (variance ratio) test. The significance of the difference among the treatment combinations means was estimated by the Duncan’s Multiple Range Test (DMRT) at a 5% level of probability.

Achievement/Findings:

In this study, organic manures played a significant role in the enhanced growth and yield performance of tomato in a sustainable production system. BARI Tomato 15 coupled with poultry manure enhanced vegetative and reproductive growth with a higher yield of tomato by the slow and steady release of nutrients to the plants compared to other treatments. Thus the application of BARI Tomato 15 coupled with poultry manure can reduce the cultivation cost of tomato while minimizing pollution by excessive use of synthetic fertilizers and could be considered as a good production strategy for obtaining high yields with lower impact on the environment.
