Abstract/ Executive Summary:

The field experiment was conducted on watermelon at Regional Horticulture Research Station, Bangladesh Agricultural Research Institute, Lebukhali, Dumki, Patuakhali during the winter season of 2017 and 2018 to study the effect of different mulching material on weed control performance, yield, and quality of watermelon. All the weed control parameters, plant growth, yield, and quality characters were superior with silver on black polyethylene mulch and ash color polyethylene mulch while, plants without mulch (control) resulted in poor growth and yield for poor weed control. From an economic point of view, silver on black polyethylene mulch and ash color polyethylene mulch resulted in the highest net return and found to be more economical with the highest cost: benefit ratio.

Start Date: 00-00-2017

End Date: 00-00-2018

Program Area: Crop-Soil-Water Management

Commodity: Water melon, Mechanical weed management

Objectives:

1. To find out effective and economically viable mulching material for watermelon.

2. To find out the effect of mulching material on weed control, growth and yield of watermelon.

Methodology:

The field experiment was conducted on watermelon at Regional Horticulture Research Station, Bangladesh Agricultural Research Institute, Lebukhali, Dumki, Patuakhali during winter 2018. The experiment was laid out in Randomized Block Design with three replications. There was a total of four treatment of mulching materials viz., ash color polyethylene mulch (T₁), silver on black polyethylene mulch (T₂), Blue polythene mulch(T₃), Rice straw mulch (T₄), two hands weeding (T₅) and Control (T₆) without mulch. Mulching applied up to 25 cm both the side from the stem of watermelon. The thickness of three polyethylene much was 30 micron while rice straw much was applied at 4 inches thick. 15 days old single seedling of cv. Big Family was planted on 25 January 2018 at 1.5 m x 1 m spacing. The fertilizers were applied at the rate of 75:40:40 NPK kg/ha (M.M Islam et. Al. 2014-15). A full dose of P₂O₅ and K₂O was applied as basal dose and nitrogen was given in two equal splits as basal and top dressing at 20 DAS. The farmyard manure @ 20 tonnes per hectare was mixed in soil uniformly to all the treatments. The observations on growth, flowering, yield, and quality parameters were recorded and subjected to statistical analysis of variance technique as described by Panse and Sukhatme (1985).

Achievement/Findings:

It is concluded that the application of silver on black and ash color polythene mulch is beneficial than other organic mulches in improving the yield quality and economically beneficial of watermelon production. This polythene mulch reduces the labor for weeding. So, ultimately reduce the production cost. An increase in yield along with other advantages of mulching may further help the farmers to grow watermelon on a large scale.
