Abstract/ Executive Summary:

An experiment was conducted at Bangladesh Agricultural Institute Farm during 1974 wet season to determine the optimum depth of seeding on the yield of soybean. Significant differences were observed among different depth treatments with respect to seed-yield, number of pods per plant, number of seeds per plant, number of plant population and germination percentage. But 100 seed weight, and plant height remained unaffected significantly by the depth treatments. The highest seed yield was 2623.76 kg/ha obtained from 6 cm depth and followed by 2352.48 kg/ha and 2324.68 kg/ha from 3 cm and 9 cm, respectively. The yield gap between optimum depth (6 cm) and deepest depth ( 9 cm ) was 299.10 kg/ha.

Keywords: Effect, Seeds, Depth, Soil, Soyabean

Location: Bangladesh Agricultural Institute Farm, Tejgaon, Dhaka

Start Date: 00-05-1974

End Date: 00-10-1974

Program Area: Seed Technology

Commodity: Soybean

Objectives:

To determine the optimum depth of seeding on the yield of soybean

Methodology:

The experiment was conducted at the Bangladesh Agricultural Institute Farm, Tejgaon, Dacca, during the months of May to October, 1974. The Meteorological data during the experimental period showed that the total rainfall was 80.34 inches; maximum temperature =F 89⁰F ; minimum temperature = 79°F and relative humidity=88%. The moisture contents of the soil at the depth of 3, 6 and 9 em were 12.5, 14.7 and 16.9%. respectively. The soil was analyzed and the results were obtained as follows : pH range =5.4-5.9 . Organic matter content=2.09 Loss on ignition=0.l1% Total P₂0₅ =0.06% Total K.₂0=0.78% The experiment was laid out in randomized complete block design with four replications on a photosensitive variety (S-3). The plants were spaced at 45 x 5 cm. The treatment comprised of three different levels of depths of soils for the placement of seeds such as D₁ =3 cm D.=6 cm, and D₃=9 cm, An area of 5 x 4 m was maintained for each unit plot. Seeds were treated with Arason, slightly moistened and pasted by inoculum (Nitragin) and then immediately sown into the furrows with different depths as prescribed in the treatments. 20-60-40 kg/ha of N-P₂0₅ --K_2.O was added to the soil as basal application. Three hand weddings were done on 25, 45 and 65 days after seeding. Insectieide (Dimecron 10- E. C.) was sprayed for three times at 20 days interval. Soybean rust and yellow mosaic virus attacked a few plants and those plants attacked by virus were removed. The yield and yield attributes were recorded and statistically analyzed.

Achievement/Findings:

Significant differences were Observed among different depth treatments with respect to seed-yield, number of pods per plant, number of seeds per plant, number of plant population an d germination percentage. But 100 seed weight, and plant height remained unaffected significantly by the depth treatments. The highest seed yield was 2623.76 kg/ha obtained from 6 em depth and followed by 2352.48 kg/ha and 2324.68 kg/ha from 3 cm and 9 cm, respectively. The yield gap between optimum depth (6 cm) and deepest depth ( 9 cm ) was 299.10 kg/ha.
