Abstract/ Executive Summary:

Experiment was conducted in Lysimeter at BINA farm, mymensingh, to find the effectiveness of drip irrigation over the conventional methods. Thirty days old seedlings of a mutant line, TM-13 (V1) Binatomato-5 (V2) were transplanted in 2m x 1m Lysimeter boxes. Irrigation was imposed at three different growth stages: vegetative 90-26 days), flowering (50-75) and fruit development (65-85 days) stages. The irrigation treatments were:T₀= Control (no irrigation);T₁ = Furrow irrigation up to field capacity at vegetative, flowering and fruit development stages;T₂= Sprinkler irrigation up to field capacity at vegetative, flowering and fruit development stages; T₃ = Irrigation with check basin method up to field capacity at vegetative, flowering and fruit development stages;T₄ = Drip irrigation using micro-tube PVC drip emitters up to field capacity at vegetative, flowering and fruit development stages;.Arrangement were made with PVC pipe providing two-drop emitters at the base of each plant to apply water drop by drop. The results indicate that drip (T₄₎ and check basin (T₃) method produced also similar yield. On the other hand, about 34 to 70% higher yield (for both the cultivars) was found in drip method. In drip method, only about one-third amount of irrigation of other methods is applied, saving about 200% water compared to other methods. Water productivity was also higher in the drip method.

End Date: 31-07-2007

Program Area: Crop-Soil-Water Management

Commodity: Tomato

Objectives:

To find the effectiveness of drip irrigation over the conventional methods.

Methodology:

A tomato experiment was conducted in Lysimeter at BINA farm, mymensingh, to find the effectiveness of drip irrigation over the conventional methods. Thirty days old seedlings of a mutant line, TM-13 (V1) Binatomato-5 (V2) were transplanted in 2m x 1m Lysimeter boxes. Irrigation was imposed at three different growth stages: vegetative 90-26 days), flowering (50-75) and fruit development (65-85 days) stages. The irrigation treatments were:

T₀ = Control (no irrigation)

T₁= Furrow irrigation up to field capacity at vegetative, flowering and fruit development stages

T₂ = Sprinkler irrigation up to field capacity at vegetative, flowering and fruit development stages

T₃ = Irrigation with check basin method up to field capacity at vegetative, flowering and fruit development stages

T₄ = Drip irrigation using micro-tube PVC drip emitters up to field capacity at vegetative, flowering and fruit development stages

Arrangement were made with PVC pipe providing two-drop emitters at the base of each plant to apply water drop by drop.

Achievement/Findings:

Drip and check basin irrigation method produced also similar yield. On the other hand, about 34 to 70% higher yield (for both the cultivars) was found in drip method. In drip method, only about one-third amount of irrigation of other methods is applied, saving about 200% water compared to other methods. Water productivity was also higher in the drip method.
