Abstract/ Executive Summary:

A field trail was conducted at the hill agricultural research station, Khagrachari and Ramgorh during the rabi season of 2007-2008 to find out the performance of hybrid maize varieties in hilly areas of Bangladesh and to compare the performances of BARI hybrid maize with commercial hybrid maize varieties. Five varieties of hybrid maize were tasted in a RCB design with three replications. Among the varieties BARI hybrid maize 5 produced maximum yield at Khagrachari (10.10 t/ha) and Pacific 984 (7.49 t/ha) at Ramgorh. The lowest yield was obtained from Pacific 984 (7.60 t/ha) at Khagrachari and BARI hybrid of maize 2 (4.55 t/ha) at Ramgorh. BARI hybrid maize 5 followed by pacific 984 may be suitable for cultivation in the hilly areas of Bangladesh.

Keywords: Performance, BARI Hybrid maize, Hilly areas

Location: RARS, Khagrachari and Ramgorh

Start Date: 00-00-2006

End Date: 00-00-2007

Program Area: Crop-Soil-Water Management

Commodity: Maize

Objectives:

i To find out the influence of hilly environment on growth, development and yield of hybrid maize

ii) To select suitable variety for hilly region.

Methodology:

The study was conducted at the hill agricultural research station, Khagrachari and Ramgorh during the rabi season of 2006-07. The trail was laid out in a RCB design with three replications. Five hybrid maize varieties viz. BARI hybrid maize 2, BARI hybrid maize 3, BARI hybrid maize 5, Pacific 11 and Pacific 984 were included in the experiment. Seeds were sown on 29 November 2006 to 12 December 2007 with a spacing of 75 cm × 25 cm. The unit plot size was 4.5m × 3m. Fertilizers @ 250-60-100-30-5-1 kg/ha N, P, K, S, Zn and B and respectively were applied. 1/3 of N and all other fertilizers were applied as basal and the remaining N was applied at two splits, at 30 DAE and at 50 DAE. Other intercultural operations such as weeding, thinning, earthing up, irrigation, pesticide application were done as and when necessary. The data were collected on days to taseling, days to silking, cob height, no. of cobs per plant, length of cob, diameter of cob, no. of seeds per cob, 1000-seeds wt. and grain yield. Collected data were statistically analyzed following MSTAT program. The differences between the means were compared using by DMRT least significant difference test.

Achievement/Findings:

It was revealed from the study that BARI hybrid maize 5 gave significantly the highest yield at Khagrachari and Pacific 984 at Ramgorh. In the last year (2006-07) BARI hybrid maize 5 performed better at Khagrachari, Boropara and Ramgorh. Therefore, it might be concluded that BARI hybrid maize 5 followed by pacific 984 may be suitable for cultivation in the hilly areas of Bangladesh.
