Abstract/ Executive Summary:

The experiment was conducted at MLT site, Kalapara, Patuakhali and MLT site Amtali, Barguna during rabi season of 2012-2013 with BARI Til 4 and BARI Surjomukhi 2 to increase the total productivity, reduce the risk of total crop failure and to increase crop diversity in the southern area of Bangladesh. Five treatments: T1: Sole sesame T2: One row Sunflower alternate with 2 row sesame T3: One row sunflower alternate with 3-row sesame T4: 100% sesame (broadcast) + 25% sunflower (broadcast) and T5: 75% sesame (Broadcast) + 25% sunflower (broadcast) were used in the study. Sole sesame gave the highest seed yields those were 1275 kg/ha and 1200kg/ ha in Kalapara and Amtali location, respectively. Although intercropping reduced sesame yield, with the addition of sunflower yield total productivity was increased in both the locations. Total productivity which is expressed in sesame equivalent yield (SEY) was highest (1990.42 kg/ha) in T2: one row sunflower alternate with 2-row sesame treatment and this treatment also gave the highest benefit cost ratio (1.76).

Keywords: Sesame, Sunflower, Intermixed cropping, Southern Districts

Location: Kalapara, Patuakhali and MLT site Amtali, Barguna

Start Date: 00-00-2012

End Date: 00-00-2013

Program Area: Farming System

Commodity: Sesame, Sunflower

Objectives:

To increase crop diversification and system productivity of the study area

Methodology:

The experiment was conducted at MLT site, Kalapara, Patuakhali and MLT site Amtali, Barguna during rabi in 2012-2013.BARI Til 4 and BARI surjomukhi 2 were used for this experiments. Five treatments were: T1: Sole sesame T2: One row Sunflower alternate with 2 row sesame T3: One row sunflower alternate with 3 row sesame T4: 100% sesame (broadcast) + 25% sunflower (broadcast) and T5: 75% sesame (Broadcast) + 25% sunflower (broadcast). The experiment was laid out in a randomized complete block design having unit plot size 8m × 5m with six dispersed replications. Seeds were sown on 04 February 2013 at Kuakata site and on 20 January 2013 in Amtali site. Harvesting was done on 10 May and 08 May in Kuakata and Amtali site, respectively. Prior to harvest, yield contributing characters were collected from 10 randomly selected plants and yield data was recorded plot wise. The data were analyzed statistically and mean was separated by LSD test.

Achievement/Findings:

Sole sesame gave the highest seed yields of 1275 kg/ha and 1200kg/ ha in Kalapara and Amtali location, respectively. Intercropping reduced sesame yield,but the addition of sunflower yield the total productivity of both the locations were increased.Total productivity which was expressed in sesame equivalent yield (SEY) was highest (1990.42 kg/ha) in one row sunflower alternate with 2-row sesame treatment (T2) and this treatment also gave the highest benefit cost ratio (1.76).
