Abstract/ Executive Summary:

To study the effect of planting geometry on yield and yield attributes of maize hybrids an experiment was conducted at the Regional Agricultural Research Station, Jamalpur during rabi 2009- 2010 and 2010- 2011. The results revealed that there was significant variation among the planting geometry during both years. There was no significant difference among the varieties in the first year but in the second year. The highest grain yield was obtained from the planting geometry 60cm × 20cm (83,333 plants m^-2) which was statistically similar to that of 75cm × 20cm (66,666 plants m^-2). The lowest grain yield was obtained from the planting geometry 75cm × 25cm (53,333 plants m^-2). Pacific-11 showed better performance during both years than the varieties BARI hybrid bhutta-5 and BARI hybrid bhutta- 7. Significant variation was not found due to interaction effect of variety and planting geometry.

Start Date: 00-00-2009

End Date: 00-00-2011

Program Area: Crop-Soil-Water Management

Commodity: Maize

Objectives:

To find out season based appropriate planting geometry for hybrid maize varieties.

Methodology:

The experiment was conducted at the Regional Agricultural Research Station, Jamalpur during rabi 2009-2010 and 2010-2011 to find out season based appropriate planting geometry for hybrid maize varieties. The experiment comprised three maize hybrids viz. BARI hybrid bhutta-5, BARI hybrid bhutta-7 and Pacific-11, and three planting geometry viz. 75cm × 25cm (53333 plants ha^-1), 75cm × 2 0cm (66,666 plants ha^-1) and 60cm × 20cm (83333 plants ha^-1). The experiment was laid out in a Randomized Complete Block design with three replications. Seeds were sown on 19 November 2009 and 2010 maintaining spacing as per treatments. Fertilizers were ap plied @ 250 - 55 - 110 - 40 - 5 - 1.5 kg ha^-1 of N - P - K - S - Zn - B in the form of urea, TSP, MOP, gypsum, zinc sulphate and boric acid, respectively. Half N along with full amount of other fertilizers was applied as basal during final land preparation. Remaining N was ap plied as top dress at 30 DAS after first irrigation. Weeding was done at 25 DAS while earthling- up was done at 45 DAS. Data were collected on leaf area and dry matter of plant parts at 35, 60, 75 and at 90 DAS. Ten plants were selected randomly at maturity stage to collect data on yield attributes. Yield data were recorded leaving one border line from each end of the plot. Grain yield was calculated at 14% moisture content. Grain yield was also adjusted for missing hills following the standard formula. Collected data were analyzed statistically with the help of a computer based program CROPSTAT and mean separation was done at 5% level of significance following LSD test.

Achievement/Findings:

In this experiment, planting geometry produced significant effect on yield of maize hybrids. The highest grain yield was recorded at the spacing 60cm × 20cm (83,333 plants ha^-1) and 75cm × 20cm (66,666 plants ha^-1) during both years. In conclusion, it can be suggested that any variety used in this experiment should be adjusted at 66,666- 8 3,333 plants ha^-1 to produce higher yield in this region. The variety Pacific-11 showed better performance than the varieties BARI hybrid bhutta- 5 and BARI hybrid bhutta- 7.
