Abstract/ Executive Summary:

The experiment was conducted at the research field of HRC, BARI during summer season of 2015 to 2017 followed by RCBD with three replications. Six treatments were considered as- i) Recommended dose of N as USG +2 kg B (N₁₄₀B₂) ii) Recommended dose of N as USG – B (N₁₄₀B₀); iii) 85 % recommended dose of N as USG + 2 kg B (N₁₂₅B₂); iv) 85 % recommended dose of N as USG – B (N₁₂₅B₀); v) 70 % recommended dose of N as USG + 2 kg B (N₁₀₅B₂) vi) 70 % recommended dose of N as USG – B (N₁₀₅B₀) and vii) Control. From three years study it was observed that USG and B application have the significant effects on summer tomato production. Results revealed that 85% recommended dose of N as USG + 2 kg B/ha (N₁₂₅B₂) was the productive and economically viable dose for summer tomato production. Also the higher fruit setting, fruit size and fruit quality eg.TSS were found from USG with 2 kg B treated plants.

End Date: 00-00-2018

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer, Tomato

Objectives:

1. To evaluate the effects of USG and boron application on quality summer tomato production;

2. To determine the N requirement for higher yield and quality of summer tomato and

3. To develop an USG based fertilizer recommendation for quality summer tomato production.

Methodology:

The experiment was conducted at the research field of HRC, BARI during summer 2015 followed by RCBD with three replication. Seven treatments were considered as- i) Recommended dose of N as USG +2 kg B (N₁₄₀B₂) ii) Recommended dose of N as USG – B (N₁₄₀B₀); iii) 85 % recommended dose of N as USG + 2 kg B (N₁₂₅B₂); iv) 85 % recommended dose of N as USG – B (N₁₂₅B₀ ); v) 70 % recommended dose of N as USG + 2 kg B (N₁₀₅B₂) vi) 70 % recommended dose of N as USG – B (N₁₀₅B₀) and vii) Control. A blanket dose of other fertilizers was applied @ P₄₅K₉₀S₂₀Zn₃ kg/ha. Plot size was 4.8 m × 1.2 m under tunnel and paired row system with 60 cm × 40 cm plant spacing was followed. BARI Hybrid Tomato-8 was used as a test crop and transplantation was made in 12 July 2015 and 13 July 2016. USG was applied at 15 DAT in ring method and deep placement at a depth of 7-8 cm in soil and 9 -10 cm a part from plant. But, PKS and other fertilizers were applied as a blanket dose as per recommendation during final land preparation. Chemical analysis of initial soil sample was done and result was presented in table A. Data were recorded on different parameters and analyzed followed by MSTATC program.

Achievement/Findings:

From three years study it was observed that USG and B application has significant effects on summer tomato production. In 2015, recommended USG with 2 kg B/ha performed better in terms of yield and 85 % recommended USG with 2 kg B/ha showed best performance in terms of economic profitability. But in 2016, 85 % recommended USG with 2 kg B/ha showed best performance in terms of both yield and economic profitability. In 2017, maximum yield was obtained with T₁ followed by T₃ but T₃ treatment was economically profitable dose for summer tomato production. Higher fruit setting, fruit size and quality eg.TSS were found from USG with 2 kg B treated plants. So it could be concluded that 85% recommended dose of N as USG + 2 kg B/ha (N₁₂₅B₂) with other fertilizers @ P₄₅K₉₀S₂₀Zn₃ kg/ha was the productive and economically viable dose for summer tomato production.
