Abstract/ Executive Summary:

An experiment was conducted at Hill Agricultural Research Station, Khagrachari during the Rabi season of 2013-14 to find out suitable local french bean varieties intercropped with hybrid maize under different planting system in hilly areas higher productivity and economic return. Six intercropping combinations viz., maize single row (75 cm × 25 cm) +2 rows french bean (black seed), maize single row (75 cm × 25 cm) + 2 rows french bean (pink seed), maize single row (100cm × 25 cm) + 3 rows french bean (black seed), maize single row (100 cm × 25 cm) + 3 rows french bean (pink seed) , maize single row with 2 plants/ hill (100 cm × 50 cm) + 3 rows french bean (black seed) and maize single row with 2 plants/hill (100 cm × 50 cm) + 3 rows french bean (pink seed) were evaluated against their sole crops. Maize single row + 3 row French bean (pink seed) intercrop combination might be suitable for higher productivity and economic return for the hill valley of Khagrachari. The medium cob yield (12.05 t/ha) and fodder yield (22.77 t/ha) and the highest seed yield (6.84 t/ha) were found in this combination. The highest gross return (Tk.3,99,793/ha), net return (Tk.3,34,793/ha) and benefit cost ratio (6.15) were recorded in the same combination.

Objectives:

To find out suitable local French bean varieties intercropping with hybrid maize under different planting system in hilly areas
To increase total productivity and economic return through suitable combination.

Methodology:

The experiment was conducted at the Hill Agricultural Research Station, Khagrachari during the Rabi season of 2013-14. Seven treatment combinations were as follows: T₁=Maize single row (75 cm × 25 cm) + 2 rows french bean (black seed), T₂=Maize single row (75 cm × 25 cm) + 2 rows french bean (Pink seed), T₃=Maize single row (100 cm × 25 cm) + 3 rows french bean (black seed), T₄=Maize single row (100 cm × 25 cm) + 3 rows french bean (pink seed), T₅=Maize single row with 2 plants/ hill (100 cm × 50 cm) + 3 rows french bean (black seed), T₆=Maize single row with 2 plants/ hill (100 cm × 50 cm) + 3 rows french bean (pink seed), T₇=Sole maize. The experiment was laid out in randomized complete block design with three replications. The unit plot size was 4 m × 4 m. The hybrid maize (var. BARI hybrid maize 7) and French bean local black and pink colour were used in this experiment. Seeds of maize and French bean were sown on 02 December 2013 according to treatments. Sole hybrid maize and intercropping treatments were fertilized with 250-55-110-40-4-2 kg/ha of N P K S Zn B. For sole maize and intercrop the full amount of P K S Zn B and ¹/₂ N were applied as basal in the form of triple super phosphate, muriate of potash, gypsum, zinc sulphate, boric acid and urea, respectively. The remaining N was top dressed at 30 days after sowing (DAS). Irrigation was given after sowing/planting for proper establishment of crops. Subsequently three irrigations were applied at 30, 60 and 90 DAS. Data of both the crops were analyzed statistically and the means were adjusted using LSD. Benefit cost analysis was also calculated.
