Influence of Organic and Inorganic Fertilizer on Garlic

Chief Scientific Officer & Head, OFRD and Relevant Scientists of OFRD

Abstract/ Executive Summary:

The experiment was conducted in the farmers’ field of Trishal, Mymensingh during the Rabi season of 2014-15 to evaluate the effect of nutrients on garlic and to find out the optimum fertilizer dose for garlic production. The experiment was laid out in RCB design. There were six fertilizer doses as: T₁= Recommended fertilizer dose for HYG (N100P48K80S30 kg ha^-1 with 5 t ha^-1 cowdung), T₂= T₁ + 5 t ha^-1 cowdung, T₃ = T₁+ 1.5 t ha^-1 vermicompost, T₄= STB (N90P42K72S20 kg ha^-1) + 5 t ha^-1 cowdung, T₅ = STB (N90P42K72S20 kg ha^-1) + 1.5 t ha^-1 vermicompost and T₆= Farmers’ practice. Garlic variety BARI Rashun-2 was used as test crop. STB + 1.5 t ha^-1 vermicompost (T₅) produced significantly the highest garlic bulb yield (8.64 t ha^-1). The lowest yield (5.19 t ha^-1) was found from farmers’ practice.

Keywords: Garlic, Fertlizer, Yield

Location: Rampur village of Trishal under Mymensingh district

Start Date: 00-00-2014

End Date: 00-00-2015

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer

Objectives:

To ascertain the response of garlic to different rates of organic fertilizer (vermicompost, cowdung etc) in association with inorganic fertilizer

Methodology:

The experiment was conducted at Rampur village of Trishal under Mymensingh district during Rabi season of 2014-15. The initial soil samples of the experimental fields were collected and analyzed following standard laboratory procedures .The experiment was laid out in RCB design with three compact replications. There were six fertilizer treatments as T₁= Recommended fertilizer dose (RD) for HYG(High yield goal) (N100P48K80S30 kgha^-1 with 5 t ha^-1 cowdung), T₂ = T₁ + 5 tha^-1 cowdung ,T₃ = T₁ + 1.5 tha^-1 vermicompost , T₄ = STB( Soil test based) (N90P42K72S20 kgha^-1) + 5 tha^-1 cowdung ,T₅ = STB(N90P42K72S20 kgha^-1)+ 1.5 tha^-1 vermicompost and T₆ = Farmers’ practice. Unit plot size was 3m × 3m. Cowdung, vermicompost, phosphorus and potassium were applied 5-7 days prior to clove planting and mixed thoroughly with the soil. Seed cloves were planted at a spacing of 15cm × 10cm on 15-16 November, 2014. Urea was applied as top dress at 25, 40, 60 days after planting cloves. The crop was weeded three times. Other Intercultural operations were done as and when necessary. The bulb harvesting was done on 20-22 March, 2015. Data on yield and yield components were recorded and analyzed statistically following MSTAT-C program (Gomez and Gomez, 1984).

Achievement/Findings:

Judicious application of organic manure in combination with inorganic fertilizer (STB + 1.5 t ha^-1 vericompost) was observed to be essential for yield maximization of garlic.
