Abstract/ Executive Summary:

An experiment was conducted at Olericulture Division, HRC, BARI, Gazipur, Bangladesh during the winter season of 2015-16 to develop a production package of fertilizer for tomato production under the rooftop. Eleven treatment combinations were made with organic and inorganic fertilizer combinations viz.:T₁= Absolute control; T₂= Recommended fertilizer dose (RD); T₃= 50% soil +50% kitchen waste compost; T₄= 50%soil + 50% kitchen waste compost+75% RD; T₅= 50% soil + 50% kitchen compost + 50% RD; T₆= 50% soil + 50% vermicompost; T₇= 50% soil + 50% vermicompost + 75% RD; T₈= 50% soil + 50% vermicompost +50% RD; T₉= 50% soil + 50% cowdung; T₁₀=50% soil + 50% cowdung + 75% RD; T₁₁= 50% soil + 50% cowdung + 50% RD. The pot size was10"x8" for a single plant and BARI Tomato-14 was used as planting material. Days to 50% flowering varied from 51.50 to 58.40 days. The tallest plant (88.0cm) was observed from T₂ treatment followed by T₁₁ and the shortest plant was from T₆ treatment. The highest cluster number (15.3) was recorded from T₁₁ treatment followed by T₉ and T₁₀. The highest fruit number was recorded from T₂ treatment followed by T₉ and the lowest fruit no. was recorded from T₃, T₄, T₅ treatment and varied from 15.0-17.3. The highest identical average fruit wt. was recorded from T₁₀ and T₁₁ (70.0g) treatment and the lowest was recorded from T₄ (22.5g). Maximum fruit length and breadth were observed from T₂ (5.2cm and 3.8cm). The highest identical fruit yield (56.4, 59.5t/ha) was observed from T₁₀ and T₁₁.

End Date: 00-00-2016

Program Area: Crop-Soil-Water Management

Commodity: Tomato, Soil fertility

Objectives:

To develop a production package for tomato with different nutrient combination under roof top gardening.

Methodology:

The study was conducted at Olericulture Division, Horticulture Research Centre, Bangladesh Agricultural Research Institute, Gazipur in the winter season of 2015-2016. The experiment was carried out in a Randomized Complete Block (RCB) design with three replications. Each replication comprised of eleven treatment combinations. The pot size was 10'' X 8'' accommodating one plant in each pot. The variety BARI Tomato-14 was used as planting material in this study. Tomato seeds were sown on November 18, 2015, and planting was done on 17 December 2015. Treatment combinations were viz., recommended dose of chemical fertilizer, kitchen waste compost, vermicompost and soil combination : T₁= Absolute control; T₂= Recommended fertilizer dose (RD) (N-P-K-S-Zn-B @253- 90-125- 21-4.9-2kg / ha) respectively; T₃= 50% soil ₊ 50% kitchen waste compost; T₄= 50%soil + 50% kitchen waste compost+75% RD; T₅= 50% soil + 50% kitchen waste compost + 50% RD; T₆= 50% soil + 50% vermicompost; T₇= 50% soil + 50% vermicompost + 75% RD; T₈= 50% soil + 50% vermicompost +50% RD; T₉= 50% soil + 50% cowdung; T₁₀=50% soil + 50% cowdung + 75% RD; T₁₁= 50% soil + 50% cowdung + 50% RD. The entire amount of P, K,S, Zn, B and one-third of N were and other organic fertilizer (according to treatments) were applied during final land preparation. The remaining two-thirds of N was applied at 15 and 30 days after planting. Irrigation, pruning, mulching, weeding and other intercultural operations were done as and when necessary. Plant protections were done as and when necessary. Data on days to 50% flowering, plant height at last harvest, number of cluster/plant, fruit length, breadth, number of fruit per plant, individual fruit weight, fruit yield per plant and percent of virus infestation were recorded. The collected data were statistically analyzed (Gomez and Gomez, 1983).

Achievement/Findings:

Considering earliness, yield and horticultural traits recommended fertilizer dose with combination of cowdung (T₁₀and T₁₁) showed the better results. The trial will be repeated for next year for further confirmation.
