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 & 2002. On an average, result revealed that the highest seed yield was obtained where fertilizer was applied along with one hand weeding at 20 days after sowing (980 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 (465 kg/ha) whereas yield of one hand weeding at 20 days after sowing was also nominal (595 kg/ha).

Keywords: Sesame, Management practices, Performance

Location: Narikeli, Jamalpur

Start Date: 19-03-2001

End Date: 22-06-2002

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 & 2002 to determine the package of improve management practices for higher yield of sesame under AEZ 9. The experimental area was 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 P₂O₅ and 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 March 19-24, 2002 and the crops were harvested from June 7-11, 2001 and June 18-22, 2002. The data on the yield attributes were collected from 10 randomly selected plants collected prior to harvest from each plots. The collected data were analyzed statistically and means were separated with DMRT test.

Achievement/Findings:

The highest plant height was obtained from treatment T3 which was statistically at par T2 and the lowest height from T1. Similar trend was followed in case of plant/m², branches/plant, capsule/plant and seeds/capsule. All the characters showed the lowest in sowing without post care. Significantly the highest seed yield was obtained from fertilizer with one hand weeding at 20 DAS which might be due to higher branches/plant, capsule/plant, seed/capsule. It is revealed that 94% increase yield was achieved with fertilizers and weeding. Only one hand weeding also showed 27% higher yield than without post sowing care. This treatment showed the lowest yield among the treatments. 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). Jain et al. (1985) opined that weeds offered a serious competition to sesame plants and caused a reduction in yield to the extent of 46% to 76% which was more or less concurrent with the present findings (29%). 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.
