Abstract/ Executive Summary:

Field experiment was conducted at the Central Research Station of Bangldesh Agricultural Research Institute (BARI), Joydebpur, Gazipur during the period from December to May in 2013-14. Three sowing and harvesting date was used in this experiment to investigate the effect of sowing and harvesting time on yield and seed quality of Soybean. The highest seed yield (1629 kg/ha) was obtain from the 30 Dec sowing and harvesting from 130 DAS.

Keywords: Sowing and harvesting time,Yield, Seed quality,Soybean

Location: At the Central Research Station of Bangldesh Agricultural Research Institute (BARI), Joydebpur, Gazipur

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Seed Technology

Commodity: Soybean

Objectives:

To investigate the effect of sowing and harvesting time on yield and seed quality of Soybean.

Methodology:

The experiment was conducted during the winter seasons of 2013-14 at the research field of Seed Technology Division, BARI, Gazipur. The experiment was laid out in a randomized complete block design (RCBD) with three replication. Three planting dates viz. S1=15 Dec, S2=30 Dec, S3=15 Jan and three harvesting date viz. H1=120 DAS, H2=130 DAS, H3=140 DAS were used in the study. The unit plot size was 4m 3m . Row to row and plant to plant distance was 40cm 5cm respectively.The crop was fertilized @ 25,35, 55 & 18 of N, P, K& S (FRG, 2005), half of urea and all other fertilizers were applied during final land preparation. The rest of the urea was applied at the initial stage of flowering. Weeding cum thinning irrigation, insect and disease control when necessary works were done as per requirement. At maturity 10 randomly selected plants were up rooted for data collection. Data was collected on plant height, No. of branch/plant. No. of pod/plant. No. of seed/plant, 100 seed wt., Seed yield (kg/ha), Germination (%). Total protein and oil content were determined using the micro Kjekahl methods and soxhlet apparatus. Collected data were statically analyzed and treatment means were compared by DMRT.
