Abstract/ Executive Summary:

An experiment was conducted at Joydebpur during rabi 1989-90 and 1990-91 to find out the suitable maize composite and optimum seed rate for higher yield of fodder. Green fodder yield, density/sq.m. and plant height were significantly affected by seed rate and varieties. Average over the years, BFC-3 gave highest fodder yield (42.45 t/ha) with 60 kg seed/ha, The other two composites yielded higher with same seed rate but their yields could not exceed the yield of BFC-3 In both the years of trial.

Keywords: Seed rate, Fodder yield, Maize composites

Location: Joydebpur, Gazipur

Start Date: 00-00-1989

End Date: 00-00-1991

Program Area: Animal Health and Management

Commodity: Fodder, Maize

Objectives:

To find out the optimum seed rate of different maize varieties for high production of fodder.

Methodology:

The experiment was carried out on silty clay loam soil (pH6.5) at Joydebpur during rabi season (December 1989 to February 1990 and November 1990 to February 1991). Three seed rates (30, 45 and 60 kg/ha) and three composites of maize (Barnali ,BFC-3 and Savar- 1) were tested. A split plot design with three replications was used with seed rate as main plot and varieties in sub plot. Seeds were sown on December 3, 1989 and November 26, 1990. The unit plot size was 5m x 3m. Fertilizers were applied at the rate of 120 kg N, 60 kg P₂0₅, 50 kg k₂0, 20 kg S and 5 kg Zn/ha in the form of Urea, Triple Superphosphate (TSP), Muriate of Potash (MP), Gypsum and Zinc sulphate, respectively. All the TSP and MP fertilizers and 40 kg N were applied basically. The remaining nitrogen was applied as topdress in two equal splits, 30 and 60 days after emergence followed by irrigation. Total rainfall was recorded during the month of December, January, February and March were 6.4, 0.0, 26.4 and 240.0 mm respectively during 1989-90 and 4.2, 13, 5.4 and 25.8 mm in 1990-91. Plants were harvested at silking stage on March 10, 1990 and March 3, 1991. Observations were made on the plant height at harvest and yield components from 10 randomly selected plants per plot. Data on number of plants/m² were taken from three randomly selected quadrats each of 1m² in all plots before harvest. For yield estimation 4m x 2m was harvested where 50 cm was discarded around the plot. The collected data were analyzed statistically and means were compared by least significance difference (LSD).

Achievement/Findings:

The result indicated that the composite BFC-3 should be grown with 60 kg/ha seed rate for higher fodder yield at Joydebpur. However, further research with higher seed rate would be interesting to corroborate the results obtained.
