Abstract/ Executive Summary:

A field experiment was conducted in the farmer’s field of FSRD site, Kadamshahar, Rajshahi during 2007-08 to find out the suitable maize variety (s) that will be fitted well in Potato-Maize cropping pattern for higher grain yield and economic return. Six hybrid maize varieties viz. Pacific-60, Pacific-11, Pacific-984, NK-40, BARI Hybrid Maize-5 and BARI Hybrid maize-3 were tested in the farmer’s field of HBT. Among the tested varieties, higher grain yield (6.56 t/ha) was produced by BARI hybrid maize-5 followed by NK-40 (5.95 t/ha) and Pacific-984 (5.93 t/ha) while the lowest grain yield was found in Pacific-60 (4.93 t/ha).

Keywords: Hybrid, Maize, Potato, Cropping pattern

Location: FSRD site, Kadamshahar, Rajshahi

Start Date: 05-12-2006

End Date: 14-06-2007

Program Area: Farming System

Commodity: Potato, Maize

Objectives:

To find out the suitable variety of maize for obtaining higher yield and economic return to cultivate after potato crop in High Barind Tract

Methodology:

The experiment was conducted at the FSRD site, Kadamshahar, Rajshahi during rabi 2007-08 in the farmers’ field of High Barind Tract. The experiment was conducted after harvesting of potato. The potato variety Cardinal was cultivated as per BARI recommended practice. The crop was sown on 5 December 2006 and harvested on 5 March 2007. After harvest of potato the plot was divided into six sub plots (3 m x 3 m) maintaining 1 m distance between two sub plots. The unit plots were fertilized with 108-35-60-15-1 kg/ha N-P-K-S-Zn, respectively. Six maize varieties viz., Pacific-60, Pacific-11, Pacific-984, NK-40, BARI Hybrid Maize-5 and BARI Hybrid maize-3 were sown on 6 March 2007. The spacing was 75 cm distance between rows and 25 cm between two plants. The crops were harvested on 14 June 2007. The data on different yield and yield contributing characters of maize were collected from randomly selected 10 plants from each plot and yields were recorded plot wise. The data were analyzed statistically and economic analysis was done for gross return, gross margin and marginal benefit cost ratio.

Achievement/Findings:

Among the maize varieties significant variation was observed on the yield and yield contributing characters except cob length and straw yield. BARI hybrid maize-3 produced the highest height (223.27 cm) that is identical to Pacific-984 (219.53 cm) and Nk-40 (219.20 cm) and the lowest plant height (206.33 cm) was observed in Pacific-11. The highest number of grains/cob (547) was recorded in BARI hybrid maize-5 followed by Pacific-984 (482.75) and the lowest number of seeds/cob was found in NK-40 (403.06). The highest grain weight/cob (201.53 g) was obtained from BARI hybrid maize-5. Similar trend was followed in case of 100-grain weight. The highest grain yield (6.56 t/ha) was recorded in BARI hybrid maize-5 followed by NK-40 (5.95 t/ha) and Pacific-984 (5.93 t/ha) and the lowest grain yield (4.93 t/ha) was found in Pacific-60. Higher yield was recorded from BARI hybrid maize 5 due to higher yield attributes than other varieties. The highest gross return (Tk.72690/ha) as well as gross margin (Tk.49140/ha) were recorded from BHM-5.Among the tested varieties of hybrid maize, three promising varieties (BHM-5, NK-40 and Pacific-984) were found suitable for kharif I season.
