Abstract/ Executive Summary:

A field experiment was carried out at the Horticultural farm of the Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur, during September 2006 to April 2007 to investigate growth and yield of sweet pepper as influenced by spacing. There were three levels of spacing viz. 50×50 cm, 50×40 cm, 50×30 cm. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Data were recorded on various parameters and subjected to statistical analysis. The plant spacing had significant variation in almost all the growth and yield components except pericarp thickness. Number of branches per plant, number of leaves per plant, stem girth, number of fruits per plant, days to first harvest, fruit length, individual fruit weight, yield per plant were found to be significantly increased with the increasing of plant spacing but plant height at different stages, number of fruits per plot, days to 50% flowering, fruit breadth, yield per plot and yield per hectare were found to be significantly increased with the decreasing plant spacing. Considering the yield of fruits per hectare, cost of production and net return, 50×30 cm spacing appeared to be recommendable for the cultivation of sweet pepper.

Start Date: 00-09-2006

End Date: 00-04-2007

Program Area: Crop-Soil-Water Management

Commodity: Chilli

Objectives:

Objective of the study was to investigate growth and yield of sweet pepper as influenced by spacing.

Methodology:

The experiment was conducted at the Horticultural farm of the Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur, during the Kharif and Rabi season (September 2006 to April 2007). The experimental area is situated at 24^o00' N latitude and 90^o25' E longitude at an elevation of 8.4 meters from the sea level. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. There were in total 9 unit plots, each plot of 3×1 m were made and raised by 10 cm which was separated by 0.50 m space. The blocks were also separated by 0.50 m space. The treatments included 3 spacing and 3 replications, such as 50×50 cm, 50×40 cm, 50×30 cm. The seeds were sown in October 1, 2006. Capsicum annuum var. grossum cv. California Wonder, 10 g seeds were needed for sowing. Seeds were soaked in water for 12 hour prior to sowing and thirty days old seedlings were obtained from the seedbed of the Horticultural farm of the Bangladesh Agricultural Research Institute. Half of the quantity of cowdung was applied during final land preparation. The remaining half of Cowdung, the entire quantity of TSP, ZnO, Gypsum and one third each of urea and MP were applied during pit preparation. The rest of Urea and MP were applied in two equal splits, 25 and 50 days after transplanting in the main field. Thirty days old seedlings were transplanted on experimental plots at each planting time with 2 cm depth maintaining single seedling per hill. After planting the seedlings, the following intercultural operations were accomplished for their better growth and development. The crop was irrigated when needed depending on the moisture status of the soil and requirement of plants. Plots with transplanted seedlings were regularly observed to find out any damage or dead seedlings for its replacement and weeding was done as per requirement and also plant protective measures were done against insect and disease. Data were collected from five plants were randomly selected from each plot for data collection on growth and yield characteristics during the growth of plants and at harvesting time of the crop. These were plant height (cm), number of branches per plant, number of leaves per plant, stem girth (mm), fruit length (cm), fruit breadth (cm), days 50% to flowering, days to 1st harvest, number of fruits per plant, individual fruit weight (g), yield per plant (g) and yield per plot (kg). The recorded data for different characters were analyzed statistically using ‘MSTAT-C’ program to find out the significance of variation among the treatments. The analysis of variance was performed by F-test, while the significance of difference between the pairs of treatment means were evaluated by the Duncan’s Multiple Range Test (DMRT) test at 5% and 1% level of probability.
