Abstract/ Executive Summary:

The experiment was conducted at the Horticulture farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during October 2013 to September 2014. Four varieties of Chilli V₁ (Magura), V₂ (Kajoli), V₃ (Vaduria) and V₄ (Bogra Morich) showed wide differences in their genotypic constituents reflected by morphological status. Major characters of growth and yield such as plant height, days to first flower bud initiation, number of flowers/plant, number of fruits/plant, number of fruits/plot, individual fruit weight, fruit length, fruit diameter, yield/plant, yield/plot, dry weight of fruit/plant, number of seed/fruit and Vitamin C content were influenced by cultivars. However, the maximum number of fruits (265.5/plant and 2949.0/plot), yield (291.3 g/plant and 4.6 kg/plant), dry weight of fruit (100.7 g/plant) and Vitamin C (83.1 mg/100 g fruit) was found from V₂, while minimum from V₄.

Keywords: Capsicum frutescens, Cultivars, Growth and yield

Location: Horticulture farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh

Start Date: 00-10-2013

End Date: 00-09-2014

Program Area: Crop-Soil-Water Management

Commodity: Chilli

Objectives:

To study the vegetative growth and yield response of Chilli.

Methodology:

Experimental Location and Period of Study: The experiment was conducted at the Horticulture farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during October 2013 to September 2014. Genetic Materials and Experimental Design: Experiment consisted four chilli cultivars coded as V₁ (Magura), V₂ (Kajoli), V₃ (Vaduria) and V₄ (Bogra Morich) in a Randomized Complete Block Design with 3 replications. Description of the Plot: The size of unit plot was 1.6 m x 1.6 m. The distance between both blocks and plots were 0.5 m. Seedlings were planted in plot by maintaining a spacing of both plant to plant and row to row of distance 40 cm x 40 cm. Each plot contained 16 plants. Fertilization: Cow dung, Urea, TSP, MP and Borax were applied @ 10 t/ha, 210 kg/ha, 330 kg/ha, 200 kg/ha and 5 kg/ha respectively. Entire amount of Cow dung, TSP, Borax and 65 kg MP were applied during the final land preparation. Entire amount of Urea and rest of MP were applied in three installments at 25, 50 and 70 days after transplanting (DAT). Data Collection and Measuring Procedures: Data were collected on plant height, number of branches, leaf area, chlorophyll content, days to first flower bud initiation, number of flowers/plant, number of fruits/plant, number of fruits/plot, individual fruit weight, fruit length, fruit diameter, yield/plant, yield/plot, dry weight of fruit/plant, number of seed/fruit and Vitamin C content. Number of flowers/plant and number of fruits/plant was counted up to 4 months at every single day interval from the first flower and fruit. Leaf area (using CL-202 Leaf Area Meter by destructive method), chlorophyll content (using SPAD-502) were measured at 80 DAT. Fruit diameter was measured using Digital Caliper-515 (DC-515). Estimation of Vitamin C (L-Ascorbic Acid): Vitamin-C content was estimated by Oxidation Reduction Titration method. Statistical Analysis: Collected data were statistically analyzed using MSTAT-C computer package programme. Difference between treatments was assessed by Least Significance Difference (LSD) test at 5% level of significance.

Achievement/Findings:

Kajoli (V₂) cultivars generated highest number of fruits yield and Vitamin C content which was statistically identical with Vaduria (V₃) as compared to Magura (V₁) and Bogra Morich (V₄).
