Abstract/ Executive Summary:

The experiment was conducted at farmer’s field in Bandarban sadar areas daring rabi season 2004-05 and 2005-06 to find out the feasibility and profitability of growing short duration vegetables i.e., Potato (var. Heera,), lalsak (var. Red king,), spinach (var. local), and French bean (var. BARI Jharseem-2) with hybrid maize (var. Pacfic-11). The grain yield of sole maize was 9.65 t/ha whereas yield reduction was found in intercrop situation The maize equivalent yield showed that maize + spinach produced significantly higher yield (15.62 t/ha) followed by maize + lalsak (14.48 t/ha) and maize + potato (13.93 t/ha). Maize + spinach recorded the highest gross margin (Tk. 86,257/ha), but higher benefit cost ratio and marginal rate of return was accounted from maize + lalsak combination. The lowest gross margin was obtained from sole maize. It revealed that the combination of maize with lalsak or spinach were more compatible and profitable intercropping system in hill valleys of Bandarban areas.

End Date: 00-00-2006

Program Area: Farming System

Non-commodity: Intercropping

Objectives:

To examine the feasibility of growing different short duration rabi vegetables with hybrid maize in hill valleys of Bandarban.

Methodology:

The experiment was conducted on high land at hill valleys at Muslim para and Dolo para in Bandarban sadar areas during rabi season 2004-05 and 2005-06.The soil of the experimental field was sandy loam having pH 5.5 and nitrogen (N), zinc (Zn) and boron (B) was very low, but P, K and S status was medium. The site represents the area of AEZ-29. The intercrops included in the treatments were potato (var. Heera), lalshak (var. Redking), spinach (var. local), and French bean (var. BARI Jharseern-2).The variety of maize was Pacific-11. The experiment was laid out in a randomized complete block design with five dispersed farmers replications. The unit plot size was 16 m × 10 m. Potato seeds were planted in between two rows of maize with seed to seed spacing 20 cm, but French bean seeds were planted at double line with maintaining the spacing 30 cm × 10 cm. Other intercrops (spinach and lalsak) were seeded by broadcast method in whole plot. The seed rate of lalshak and spinach was 2 kg/ha and 35 kg/ha, respectively. Sowing was made 26 November to 3 December 2004 and 2005. Maize and all intercrop vegetable seeds were sown at the same time. Fertilizers were applied for maize @ 256-55-138-30-1 kg/ha N-P-K-S-B, and cowdung @ 5 t/ha. One third N and all other fertilizers and cowdung were applied as basal and rest 1/3rd N were applied at 8-10-leaf stage and 1/3rd N at tasseling stage only in maize rows as soil placement. Additional fertilizers were not applied for intercrops. All intercrops were harvested within 60-70 days after sowing. The yield data of intercrops were recorded by total harvested yield on unit plot basis and then converted into t/ha yield. The maize was harvested during 1-5 April 2005 and 10-16 April 2006. The yield contributing characters of maize were recorded from 10 randomly selected plants. The yield data were calculated by using the following yield conversion formula for maize: Adjusted Yield = CF X Plot yield, CF = M-03(N)/M-N, CF= Conversion factor, M = Optimum number of plants, N= Number of missing plants, 0.3 = Constant factor Yield = Adjusted plot yield ×10000m² Area × 100- MC%/85 X 0.8, i.e. MC 18%
