Abstract/ Executive Summary:

An experiment was carried out at the Olericulture field of Horticulture Research Centre of BARJ, Joydebpur, Gazipur during September 2006 to April 2007 to investigate yield and yield attributes of sweet pepper as influenced by plant spacing and sowing time. There were altogether 21 treatments comprising seven sowing dates viz. 1 September, 15 September, 1 October, 15 October, 30 October, 15 November, 30 November and three spacings viz. 50 × 50 cm, 50x40 cm, and 50 × 30 cm. The experiment was laid out in a Randomized Complete Block Design (factorial) with three replications. The results of the experiment showed that majority of the yield and yield components significantly varied with variation of spacing and sowing time. Only number of fruits per plant and fruit yield per plant resulted significantly higher which reflected higher yield for 1 October sowing. The number of branches per plant, number of fruits per plant, fruit length, individual fruit weight, yield per plant were found significantly increased with the increasing plant spacings but other parameters were found to be significantly increased with the decreasing plant spacing. The combined effect of sowing date and plant spacing also had significant effect on different growth and yield parameters and yield. The highest yield (19.36 t/ha) of fruit was recorded from the earlier sowing (1 October) with the closest spacing (50 × 30 cm). But reasonable yield could be obtained up to 30 October with same spacing.

Start Date: 00-09-2006

End Date: 00-04-2007

Program Area: Crop-Soil-Water Management

Commodity: Capsicum

Objectives:

To find out the optimum sowing time and spacing for higher yield of sweet pepper in Bangladesh.

Methodology:

The experiment was conducted at HRC, BARI, Gazipur during September 2006 to April 2007 and set up in a randomized complete block design (factorial) with three replications. There were seven sowing dates viz. 1 September, 15 September, 1 October, 15 October, 1 November, 15 November, and 30 November and three spacings, namely 50 × 50 cm, 50 × 40 cm, and 50 × 30 cm. Thus, there were altogether 21 treatment combinations in the experiment. Thirty days old seedlings were transplanted in the main field in each of the sowings. The crop was fertilized with cowdung @ 10 t/ha and Urea, TSP, MoP, Gypsum and ZnO @ 217, 333, 200, 111, and 5 kg/ha, respectively. Half of the quantity of cowdung was applied during final land preparation. The remaining half of the cowdung, the entire quantity of TSP, ZnO, Gypsum and one-third each of Urea and MoP were applied during pit preparation. The rest of Urea and MoP were applied in two equal splits at 25 and 50 days after transplanting in the main field. Irrigation along with other intercultural operations were done as and when needed. Data on different yield contributing characters were recorded and analyzed statistically. The mean data were separated by DMRT for interpretation of the results.

Achievement/Findings:

Considering the above findings, 1 October sowing along with lowest spacing (50x30 cm) appeared to be suitable for higher fruit yield but sweet pepper could be sown up to 30 October with same spacing for reasonable fruit yield. These findings need to be verified at different AEZs of Bangladesh.
