Abstract/ Executive Summary:

Field experiments were carried out to determine the effects of seeds collected from different parts on growth, yield and yield attributes of lentil. Lentil seeds of three varieties (BARI Masur-2, BARI Masur-3 and BARI Masur-4) were collected from different parts i.e. P1: collection of pods from upper parts of lentil plants, P2: collection of pods from middle parts of lentil plants, P3: collection of pods from lower parts of lentil plants prior to harvesting. All the seeds were stored in earthen pot until conducting the laboratory study. Non-significant variation was observed in three varieties of lentil for most of the parameters studied. The highest plant height, pods plant-1, seeds pod-1, 1000- seed weight and seed yield were observed in BARI Masur-4 and the lowest in BARI Masur-2. Seeds collected from middle parts of lentil recorded the highest pods plant-1, seeds pod-1 and seed yield (804 kg ha-1 in 2004-05 and 838 kg ha-1 in 2005-06). BARI Masur-3 seeds were collected from middle parts and BARI Masur-4 from lower parts recorded higher seed yield (1003 kg ha-1 in 2004-05 and 1012 kg ha-1 in 2005-06 for BARI Masur-3 x P2, 1061 kg ha-1 in 2004-05 and 856 kg ha-1 in 2005-06 for BARI Masur-4 x P3).

Start Date: 00-00-2004

End Date: 00-00-2006

Program Area: Crop-Soil-Water Management

Commodity: Lentil

Objectives:

The experiment was conducted to determine the effects of seeds collected from different parts of lentil to get maximum seed yield.

Methodology:

Experiments were carried out at the Research Field of the Pulse Research Centre, Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur, Bangladesh during the period from Rabi season of 2004-05 and 2005-06. The experiment was conducted to determine the effects of seeds collected from different parts of lentil. Lentil seeds of three varieties viz. BARI Masur-2 (V1), BARI Masur-3 (V2) and BARI Masur-4 (V3) were collected from the Pulses Research Centre experimental field in Rabi seasons of 2003-2004 considering three different parts i.e. P1: collection of pods from upper parts of lentil plants, P2: collection of pods from middle parts of lentil plants, P3: collection of pods from lower parts of lentil plants prior to harvesting. All the seeds were stored in earthen pot until conducting the laboratory study. The collected seeds were preserved in the earthen pot. Before setting up the field experiment, laboratory experiment was carried out for recording the seed quality data (moisture percentage, germination percentage, vigour etc.). The experimental field was well drained high land with moderately even topography having irrigation facilities. The area belongs to the Agro-ecological Zone (AEZ 28) under Madhupur Tract. The experimental site is situated at 24.00^o North Latitude and 90.26^o East Longitude. Field experiments were conducted with the above seeds. The experiments were conducted in a factorial randomized complete block design. The row to row spacing was 30 cm and plant to plant 10 cm. The unit plot size was 3 m x 4 m. Seeds were sown on 18 November 2004 and 11 November 2005 and harvested on 01 March 2005 and 25 February 2006. Among the ten rows of each plot, middle 6 rows were kept for harvesting per plot seed yield. Outer two rows except the border rows from each side were used for sampling of plant height. After harvesting, 10 plants from each plot excluding border lines were selected randomly and tagged by a sample stick to record necessary data. The sample plants were uprooted carefully from the soil. The following growth, yield and yield-contributing characters were recorded. Plant height: The data on plant height were recorded by taking 5 randomly selected plants from each plot at different days after sowing (DAS) (i.e. 20 days interval). The data on plant height were expressed in cm. Days to 1st flowering: Days to 1st flowering was counted from the date of sowing to the date of 1st flowered in each plot. Days to 50% flowering: Days to 50% flowering was counted from the date of sowing to the date of 50% of plants flowered in each plot. Days to maturity: Days required from the date of sowing to maturity of a plant were recorded. Pods plant-1 Total number of pods was counted from ten selected plants separately. Seeds pod-1 Ten pods were selected randomly from the bulk of the pods harvested from ten selected plants and numbers of seeds are counted individually from each of them. 1000-seed weight: For seed weight, 1000-seeds were counted and their dry weight was taken. Seed yield: Yield data were collected from 3 m x 1.8 m area of each plot and the yields were converted to kg ha-1. Lentil crops were harvested on 01 March 2005 in first year and on 25 February 2006 in second year. The harvested seeds were threshed, cleaned, and dried properly. Data on yield and yield components i.e. seed yield (kg ha-1), pods plant-1, seeds pod-1, 1000-seed weight was recorded. Each seed sample was then divided into three and stored in earthen pot for next growing season. Statistical analysis: The data for different characters were compiled and tabulated in proper form and then subjected to statistical analysis following a computer IRRISTAT package programme adjusted the means. The correlation co-efficient and regression analysis were done for different variables wherever needed.

Achievement/Findings:

The overall results revealed that the highest plant height, pods plant-1, seeds pod-1, 1000-seed weight and seed yield was observed in BARI Masur-4 and the lowest in BARI Masur-2. Seeds collected from different parts had no effect on different parameters studied except plant height at 20 DAS in 2004-05, and 80 and 100 DAS in 2005-06, seeds pod-1 and 1000-seed weight both in 2004-05 and 2005-06. Seeds collected from middle part of lentil (P2) recorded the highest pods plant-1, seeds pod-1, 1000-seed weight and seed yield.
