Abstract/ Executive Summary:

An experiment was conducted at Hill Agricultural Research Station, Khagrachari during the Rabi season of 2013-14 to find out suitable intercropping systems of hybrid maize and chilli for increasing total productivity and economic return. Four intercropping combinations viz., maize single row (100cm × 25cm)+2 rows (50 cm × 40 cm), maize single row with 2 plants/ hill (100 cm ×25 cm) +2 rows (50 cm × 40 cm), maize single row (150 cm × 25 cm) +3 rows (50cm × 40cm) and maize single row with 2 plants/ hill (150cm × 50cm) +3 rows (50 cm × 40 cm) were evaluated against their sole crops. Cob yield of hybrid maize and yield of green chilli was the highest in respective sole crops. Maize single row (150 cm × 25 cm) + 3 rows chilli (50 cm × 40 cm) combination might be suitable and economically profitable for the hill valley of Khagrachari. The cob yield (20.90 t/ha), fodder yield (32.61 t/ha) and green chilli yield (2.04 t/ha) were found in this intercrop combination. The highest gross return (Tk.2,98,753 /ha), gross margin (Tk.2,43,753/ha) and benefit cost ratio (5.43) were also recorded in the same combination.

Program Area: Farming System

Commodity: Maize, Chilli

Objectives:

To find out suitable planting systems of hybrid maize and chilli intercropping system for higher productivity and economic return.

Methodology:

The experiment was conducted at the Hill Agricultural Research Station, Khagrachari during the Rabi season of 2013-14. Six treatment combinations were used as follows: T₁= Maize single row (100cm × 25cm)+2 rows chilli (50cm × 40cm), T₂= Maize single row with 2 plants/ hill (100 cm × 25 cm) +2 rows chilli (50 cm × 40 cm), T₃= Maize single row (150 cm × 25 cm) +3 rows chili (50 cm × 40cm), T₄= Maize single row with 2 plants/ hill (150 cm × 50 cm) +3 rows chilli (50 cm × 40 cm), T₅= Sole maize (60cm × 20cm) and T₆= Sole chilli (50 cm × 40 cm). The experiment was laid out in a randomized complete block design with three replications. The unit plot size was 4 m × 3 m. The hybrid maize (var. BARI hybrid maize 7) and chilli local (ulta morich) were used in this experiment. Seeds of maize and chilli were sown on 02 December 2013 according to treatments. Sole hybrid maize was fertilized with 250-55-110-40-4-2 kg/ha of N P K S Zn B, while sole chilli was grown with 120-80-120-20-4 kg/ha of N P K S Zn and intercrop was grown with 370-55-110-40-4-2 kg/ha of N P K S Zn B. Irrigation was given after sowing/planting for proper establishment of crops. Subsequently three irrigations were applied at 30, 60 and 90 DAE. Two hand weeding were done at 20 and 40 DAE to keep the crops reasonably weed free. Data of maize and chilli were taken from randomly selected 05 plants from each plot. Green cob of maize was harvested at 135 and 142 DAS and chilli was harvested at 118, 133 and 153 DAT.
