Abstract/ Executive Summary:

Seedling quality of capsicum grown under different growing media was evaluated in this experiment at the Olericulture farm of Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during the season of 2017-18 in order to get the ideal and healthy seedling. Seven growing media were M₁= soil : cowdung : rice hull (2:2:1), M₂= soil : vermicompost: rice hull (2:2:1), M₃= soil : cowdung : coco dust (2:2:1), M₄= soil : vermicompost: coco dust (2:2:1), M₅= soil : cowdung : ash (2:2:1), M₆= soil : vermicompost: ash (2:2:1) and M₇= soil : cowdung (1:1) as control. Each treatment was replicated three times following randomized complete block design. Results indicated that soil added with cowdung and cocodust (2:2:1) filled in polybag produced the highest seedling height (14.5 cm), greater stem diameter (2.54 mm), the highest number of leaves (9) per seedling and the highest (53.24 cm²) leaf area at 30 DAS. The highest value of seedling vigor index (236) as well as the highest seedling quality index (0.94) also observed in the same treatment.

Location: Olericulture farm of Bangladesh Agricultural Research Institute, Gazipur, Bangladesh

Start Date: 00-00-2017

End Date: 00-00-2018

Program Area: Crop-Soil-Water Management

Commodity: Capsicum, Soil fertility

Objectives:

To find out the best combination of growing media for healthy capsicum seedling production.

Methodology:

The experiment was carried out from November to December 2017 at the Olericulture farm of Bangladesh Agricultural Research Institute, Gazipur. BARI Capsicum 1 was used as planting materials. The treatments were M₁= soil : cowdung : rice hull (2:2:1), M₂= soil : vermicompost: rice hull (2:2:1), M₃= soil : cowdung : coco dust (2:2:1), M₄= soil : vermicompost: coco dust (2:2:1), M₅= soil : cowdung : ash (2:2:1), M₆= soil : vermicompost: ash (2:2:1), M₇= soil : cowdung (1:1) (control). Each treatment replicated three times following randomized complete block design. Collected rice hull, cocodust, ash and topsoil separately covered with transparent polythene sheet for one month to sterilize prior to mix. The components of media were measured by volume and mixed as per ratio of treatments. Polybags (10×15 cm) were filled with media. Seeds were first sown in a general seedbed and the second transplantation was done at two leaves stage in a polybag (10×15 cm) that filled with media combinations. Ten seedlings were randomly selected and tagged and data were collected on different growth parameters up to thirty days. Seedling vigor index was calculated according to Kharb et al. (1994) using the following formula.

Seedling Vigor Index = Seedling dry weight x Germination percentage

The quality index (QI) as proposed by Dickson et al. (1960), was originally designed for assessing the quality of young seedlings and is a product of the total dry mass (TDM) divided by the sum of the shoot: root dry mass ratio (S:R) and the ratio of stem caliper to stem length (sturdiness quotient; SQ), or QI = TDM/(S: R + SQ). Collected data were analyzed statistically by using MSTAT-C to find out the variation among different treatments. Treatment means that were significantly different were separated using Least Significant Difference (LSD) test.

Achievement/Findings:

Results of this study showed that the seedling growing media soil: cowdung : coco dust (2:2:1) produced healthy and quality seedlings as well as it had a better ability to produce higher seedling height, stem diameter, number of leaves and leaf area as well as a vigorous seedling of capsicum.
