Abstract/ Executive Summary:

This study on turmeric was conducted at Sher-e-Bangla Agricultural University, Dhaka during the period from April 2010 to March 2011. Five different fertilizer combinations were used in this experiment. Number of tiller per clump, weight of mother rhizome per plant, weight of primary and secondary finger per plant were significantly highest from F₂ and lowest from F₀. Highest turmeric yield per hectare (11.6 t/ha) was obtained from F₂ and the lowest (5.7 t/ha) was observed from F₀.

Keywords: Turmaric, Organic fertilizer, Inorganic fertilizer, Productivity

Location: Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka

Start Date: 01-04-2010

End Date: 31-03-2011

Program Area: Crop-Soil-Water Management

Commodity: Turmeric

Objectives:

To find out the suitable combination of organic and inorganic fertilizes for the better productivity of turmeric.

Methodology:

The present investigation was conducted in Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from April, 2010 to March, 2011. In this study the local turmeric variety was collected from a Nursery, in Savar. The experiment consisted of various combination of organic and inorganic fertilizers; F₀, Control (No fertilizer); F₁, 2 kg cow-dung + NPK (106g urea + 76g TSP + 68g MP) /plot; F₂, 1.2 kg poultry litter + NPK (106g urea + 76g TSP + 68g MP) /plot; F₃, 4 kg cow dung /plot; F₄, 3 kg poultry litter /plot. Each plot size was 2 m × 2 m. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The rhizome was planted maintaining 50 cm × 25 cm spacing between and within the rows. The seed rhizome was planted at a depth of 7.5 - 8.0 cm. Well-rotten cow dung (as treatment), dried poultry manure (as treatment), recommended doses of TSP (76 g/plot), MP (68 g/plot) and 50% urea (106 g/plot) were applied during final preparation of plots. Rest 50% urea was applied in two equal installments at 90 and 120 days after transplanting (DAT) of turmeric rhizomes. Earthing up was done three times throughout the whole growing period. Data were collected on different yield contributing characters and yield. The data obtained for different characters were statistically analyzed to find out the influences of different fertilizers on yield and yield contributing characters of turmeric. The mean values of all the recorded characters were evaluated and analysis of variance was performed by 'F' test. The significance of the difference among the treatment combinations of means was estimated by Duncan's Multiple Range Test at the 5% level of probability.

Achievement/Findings:

Both organic and inorganic fertilizers showed significant variations with yield and yield contributing characters. But poultry liter with recommended dose of NPK gave the best results.
