Abstract/ Executive Summary:

Package of management practices viz. sowing without post care; one hand weeding at 20 days after sowing; and fertilizer application along with one hand weeding at 20 days after sowing for higher yield of sesame (T-6) was conducted at farmers' field during the Kharif-1 season of 2001. The result revealed that the highest seed yield was obtained where fertilizer was applied along with one hand weeding at 20 days after sowing (964 kg/ha) which was equivalent to 131% higher yield compared to sowing without post care. The lowest seed yield was obtained from sowing without post care (417 kg/ha) whereas yield of one hand weeding at 20 days after sowing was also nominal (537 kg/ha).

Keywords: Sesame, Management practices, Yield, AEZ-9

Location: Narikeli, Jamalpur

Start Date: 19-03-2001

End Date: 11-06-2001

Program Area: Crop-Soil-Water Management

Commodity: Sesame

Objectives:

To determine the package of improve management practices for higher yield of sesame under Old Brahmaputtra floodplain soils of AEZ 9.

Methodology:

The experiment was conducted at FSRD, Site, Narikeli, Jamalpur during the Kharif-1 season of 2001 to determine the package of improve management practices for higher yield of sesame under AEZ 9. The experimental area was a rainfed medium highland of clay loam soil having the pH value of 5.9. The treatment include in study were i) sowing without post care; ii) one hand weeding at 20 days after sowing (DAS) and iii) fertilizer and one hand weeding at 20 DAS. The variety used was T-6 and the seed rate was 6 kg/ha. The experiment was conducted in a randomized complete block design with six dispersed replication. The unit plot size was 3m x 5m. The land was fertilized was 60 kg N, 55 kg P₂O₅and 40 kg K₂O per hectare through urea, Triple super phosphate and muriate of potash. The entire amount of fertilizer was applied at the time of final land preparation. The seeds were broadcasted on March 19-April 4, 2001 and the crops were harvested from June 7-11, 2001. The data on the yield attributes were collected from 10 randomly selected plants collected prior to harvest from each plots. The grain yield was recorded plot wise. The collected data were analyzed statistically and means were separated with LSD test.

Achievement/Findings:

All the characters except plants/m²and 1000 seed weight differed significantly due to variation in management practices . The highest plant height, branches/plant, seeds/capsule and seed yield (964 kg/ha) were recorded by the management levels where fertilizer was applied along with one hand weeding at 20 days after sowing. The possible causes of highest seed yield might be due to efficient use of nutrients and moisture caused the plants to have higher number of branches/plant, capsule/plant and seeds/capsule which eventually resulted in higher seed yield. On the other hand, only hand weeding at 20 days after sowing, the yields were nominal (537 kg/ha). The lowest yield was found in the treatment without post sowing care (417 kg/ha). The result might appear due to competition between weeds and crops for moisture and nutrients resulting in significant reduction in yield components. Similar results were also reported by Gaur and Trehan (1974). However, from the result it may be concluded that higher yield could be obtained when fertilizer was applied along with one hand weeding at 20 days after sowing which was equivalent to 131% higher yield compared to sowing without post care.
