Abstract/ Executive Summary:

A field experiment was conducted at farmer’s field of Kushtia sadar upazila under Kushtia district during the period from November 2009 to January 2012 to find out suitable mustard varieties for intercropping with sugarcane having no or negligible adverse effect on sugarcane yield. Five rapeseed/mustard varieties viz., Improved Tori -7, BARI Sarisha-9, BARI Sarisha-11, BARI Sarisha-14 and BARI Sarisha-15 were intercropped with sugarcane. Sole sugarcane was also included in this study for comparison. Among mustard varieties, BARI Sarisha-11 produced the highest seed yield (2199 kg/ha). Intercropped mustard varieties depressed cane yields by 2.79-9.96% compared to sole cane yield. The highest CEY (111.28 t/ha) was recorded in sugarcane + BARI Sarisha-11 combination.The highest gross return (Tk. 633098/ha), gross margin (Tk. 518078/ha) and benefit cost ratio (5.50) were obtained from the same combination. Sugarcane + BARI Sarisha-14 combination was close to that combination in respect of mentioned parameters. The results revealed that BARI Sarisha-11 or BARI Sarisha-14 might be grown with sugarcane as intercrop in Kushtia area for getting higher economic benefits.

Program Area: Farming System

Commodity: Mustard, Sugarcane

Objectives:

To select suitable mustard varieties for intercropping with sugarcane having no or negligible adverse effect on sugarcane yield.

Methodology:

The experiment was conducted at farmer’s field of Kushtia sadar upazila under Kushtia district during the period from November 2009 to January 2012. The soil of the experimental field was silty loam in texture with pH 7.3 belonging to Calcareous Dark Grey Floodplain soil (AEZ 11). Five rapeseed/mustard varieties viz., Improved Tori -7 (Brassica campestris, rapeseed), BARI Sarisha-9 (B campestris, rapeseed), BARI Sarisha-11 (B. juncea, mustard), BARI Sarisha-14 (B. campestris, rapeseed) and BARI Sarisha-15 (B. campestris, rapeseed) were intercropped with sugarcane. Sole sugarcane was also included in this study for comparison. The experiment was laid out in a RCB design with 3 replications. The unit plot size was 6m x 35m. Two to three eyed sugarcane sets of Isd 30 variety were planted on 05 November, 2009 and 14 November, 2010 maintaining 60 cm row to spacing. In each case, 100% seeds of rapeseed/mustard (6 kg seed/ha) were broadcast on the same day in between normal plantation of sugarcane (100%). Fertilizers were applied at the rate of 220-72-240-60-8-1 kg/ha of NPKSZnB in the form of urea, TSP, MOP, Gypsum, Zinc sulphate and Boric acid, respectively in sole sugarcane and intercropping systems (BARC, 2005). One third of N and full quantity of other fertilizers were applied as basal at the time of final land preparation. The remaining N was top dressed in two equal splits at 25 and 120 days after sowing (DAS). One weeding was done at 19 DAS. Aphids were controlled by spraying insecticide (Malathione) at 45 DAS and 52 DAS. Improved Tori-7 and BARI Sarisha-9 was harvested at 92 DAS; BARI Sarisha-14 and BARI Sarisha-15 at 95 DAS while BARI Sarisha-11 at 115 DAS in both the years Sugarcane was harvested on 29 December 2010 and 31 December 2011. Data on yield and other parameters of both the crops were recorded at the time of harvest. Plant population data for mustard varieties were taken from randomly selected three places in each plot and yield components were taken from 10 plants. Number of tiller, number of millable cane and cane yield were taken from whole plot. Millable cane height was taken from randomly selected 10 plants. Yield data of mustard were also recorded from whole plot. Data on yield and yield components of both the crops were analyzed statistically and means were adjudged by LSD test at 5% level of significance. Cost benefit analysis was also done.

Achievement/Findings:

Among mustard varieties, BARI Sarisha-11 produced the highest seed yield (2199 kg/ha). Intercropped mustard varieties depressed cane yields by 2.79-9.96% compared to sole cane yield. The highest CEY (111.28 t/ha) was recorded in sugarcane + BARI Sarisha-11 combination. The highest gross return (Tk.633098/ha), gross margin (Tk. 518078/ha) and benefit cost ratio (5.50) were obtained from the same combination. Sugarcane + BARI Sarisha-14 combination was close to that combination in respect of mentioned parameters. The results revealed that BARI Sarisha-11 or BARI Sarisha-14 might be grown with sugarcane as intercrop in Kushtia area for getting higher economic benefits.
