Abstract/ Executive Summary:

An experiment was conducted under sub tropical climatic conditions of Bangladesh during the period of winter 2009-10 and 2010-11. Interactive effect of four planting time viz. 01 September, 01 October, 01 November and 01 December with five promising strawberry cultivars viz. Sweet Charlie, Festival, Camarosa, FA 008 and BARI strawberry-1 were studied, and found that the cultivar Camarosa planted on 01 September exhibited wider fruiting duration (96.00 days) followed by Festival (93.67 days) planted on same date. The highest number of fruits plant^-1was obtained in Sweet Charlie (39.00) when planted on 01 October, while plants of BARI Strawberry-1 produced only 12 fruits when planted on 01 December. Plants of Festival planted on 01 October produced the heaviest fruit (17.78 g) followed by Sweet Charlie and Camarosa planted on same date, on the other hand, plants of FA 008 and BARI Strawberry-1 planted on 01 December produced the lightest fruit. Among the cultivar studied, Sweet Charlie planted on 01 October performed well and produced the highest yield plant^-1(667.22 g) as well as yield hectare^-1 (16.77 ton), while BARI Strawberry-1 of 01 December planting produced the lowest yield plant^-1and hectare^-1 (79.71 g and 2.247 ton, respectively). Total soluble solids (TSS) and ascorbic acid content of fruits were highly influenced by time of planting, cultivar and their interaction and found that regardless of cultivar fruits of early planted plants contained more TSS and ascorbic acid than late planted plants might be due to the fruits from early planted plants had more exposure to favourable environment, and got enough time for sugar and acid accumulation.

Start Date: 15-08-2009

End Date: 31-05-2011

Program Area: Crop-Soil-Water Management

Commodity: Strawberry

Objectives:

To study the interactive effect of planting time on growth yield and quality of selected strawberry cultivars

Methodology:

The studies were conducted at the Fruit Research Farm of Horticulture Research Centre of Bangladesh Agricultural Research Institute, (Latitude 23⁰59′ N, Longitude 90⁰24′ E, Altitude 14.33 m), Gazipur, Bangladesh during winter season of 2009-10 and 2010-11. The experiment was consisted of two factors which were: factor A- 5 cultivar: Sweet Charlie, Festival, Camarosa, FA 008 and BARI Strawberry-1; factor B- 4 planting time: 01 September, 01 October, 01 November and 01 December. The experiment was conducted in a strip-plot design with three replications. Strawberries were harvested by hand picking during early in the day while environment was cool, at an interval of 3 to 4 days and handled very carefully. Runners were removed at every 3 to 4 days intervals in order to make the crown capable to initiate flowers. Straw mulch was applied around the plants as a normal practice in order to conserve soil moisture, decreasing weed and to provide healthy condition for the fruits. Weeds were removed whenever necessary to keep the crop weed free. Irrigation was given whenever necessary to keep the soil moisture available in the field for better plant growth. All other necessary cultural practices and plant protection measures were followed uniformly for all the plots and treatments during the entire period of experimentation. The fruits were harvested at commercial maturity when >80% of the fruit surface turned red colour. Data were collected from inner plants from each row to avoid border effect. In each unit plots twenty plants were selected randomly for recording data on different morphological, vegetative, yield and chemical attributes. The data were recorded on the following parameters- plant height (cm), leaves per plant, yield (t ha^-1), total soluble solid (TSS) and ascorbic acid contents of fruit. Data on different morphological, vegetative, reproductive, yield contributing and chemical attributes were pooled and analyzed, following strip-plot design using MSTAT-C program. The mean comparison was done following the Duncan’s Multiple Range Test (DMRT).

Total Budget (Tk.) : 30,000/-

Achievement/Findings:

Considering vegetative growth, plant mortality, yield and quality of fruits 01 October planting was found to be suitable for strawberry cultivation under sub tropical condition. From this observation Sweet Charlie was found superior and considered for early planting, while Festival and Camarosa were also select as late cultivars
