Abstract/ Executive Summary:

The experiment was conducted during rabi season 2019-2020 at Agricultural Research Station, On-Farm Research Division, Alamnagar, Rangpur to find out the useful effects of organic fertilizer on the growth and yield of tomatoes. The experiment was arranged in a randomized complete block design (RCBD) with five treatments in three (03) compacted replicate blocks. The treatments included T₁: 100% Recommended Chemical Fertilizer (RCF), T₂: 85% CF + 3 t ha^-1 organic Fertilizer (OF), T₃: 85% CF + 1 t ha^-1 OF, T₄: 70% CF + 3 t ha^-1 OF and T₅: 70% CF + 1 t ha^-1 OF. The highest yield was observed in T₂ (50.59 t ha^-1) due to more number of fruit plant^-1& weight of fruit plant^-1 and the lowest was in T₅ (35.32 t ha^-1). These results may be due to the parameters of growth components increased with an increasing amount of organic and inorganic fertilizers applied. A combination of organic and inorganic fertilizer treated plots produced a higher yield than plots without the combination of organic and inorganic fertilizer. The highest gross return (BDT. 607080) was found in T₂ treatment and the lowest gross return (BDT. 423840) was recorded from T₅. The highest gross margin (BDT. 328520 ha^-1) was obtained from T₂. The lowest gross margin (Tk. 145280 ha^-1) was obtained from T₅. Integrated nutrient management (combination of organic and inorganic fertilizer) is the best option for higher tomato production in Bangladesh.

Start Date: 00-00-2019

End Date: 00-00-2020

Program Area: Crop-Soil-Water Management

Commodity: Organic fertilizer, Tomato

Objectives:

To find out the useful effects of organic fertilizer on the growth and yield of tomato.

Methodology:

Site description and experimental design: The experiment was conducted during the 2019-2020 cropping seasons at the Agricultural Research Station, On-farm Research Division, Alamanagar, Rangpur, Bangladesh located at 25⁰43.251’ N latitude and 089⁰15.735’ E longitude with an elevation of 29 m above mean sea level. The area mostly falls under high- and medium-high land of the Tista Meander Floodplain (Anowar et al., 2015; Ferdous et al., 2016). The water holding capacity of the soil is good. The area receives an average annual rainfall of around 2,160 mm with an average temperature of about 25°C (Ferdous et al., 2016). The experiment was arranged in a randomized complete block design (RCBD) with five treatments in three (03) compacted replicate blocks. The treatments included T₁: 100% Recommended Chemical Fertilizer (RCF), T₂: 85% CF + 3 t ha^-1 organic Fertilizer (OF) T₃: 85% CF + 1 t ha^-1 OF, T₄: 70% CF + 3 t ha^-1 OF, and T₅: 70% CF + 1 t ha^-1 OF. The crop variety was BARI tomato-17. Each plot measured 4m×5m. Thirty days old seedlings were transplanted on 17 November 2019. Crop management: The crop was fertilized with recommended doses of fertilizers at the rate of 207-50- 130-20-3 kg/ha of NPKSZn along with organic fertilizer as par treatments. All the fertilizers were applied at the time of final land preparation except urea and MoP. N and K were applied in three equal installments 10 days after transplanting (DAT), 22 DAT, and 36DAT. Bavistin, marshal, tafgor, secure, and acrobat were applied against late blight disease. The crop was irrigated three times at 20 DAT,37 DAT, and 75 DAT. Other intercultural operations were done as and when necessary. The harvest was done from 18 February 2020 to 22 March 2020. Data analysis: Data on yield and yield contributing characters were taken and statistically analyzed using the ‘Statistics10’ software package. Production of tomato included costs of field preparation, seed, planting, irrigation, organic manure and synthetic fertilizer, plant protection chemicals, and harvesting. Gross return under a treatment was calculated by multiplying the gross amount of crop produced by the farm-gate price. The gross margin was calculated by subtracting the cost of production from the gross return (Ferdous et al., 2017a).

Achievement/Findings:

Fertilizer application, especially for chemical fertilizer and organic manure applied to tomato fields, can be highly profitable with sustainable production increases for smallholder farming in the northern region of Bangladesh. Integrated nutrient management (combination of organic and inorganic fertilizer) is the best option for higher tomato production in Bangladesh. From the study, it can be concluded that if organic fertilizer usage can be increased then chemical fertilizer application will be decreased and soil health ultimately improved.
