Abstract/ Executive Summary:

One alternative cropping pattern T.aus-T.aman- Mustard was tested against farmers’ existing cropping pattern T.aus-T.aman-Fallow at FSRD site, Golapgonj, Sylhet under rainfed condition during three consecutive years of 1999-2000, 2000-01 and 2001-02. Alternative cropping pattern showed 246 % and 142 % higher yield over farmers’ existing pattern in T.Aus and T.Aman, respectively. The turn around times in between T.aman and mustard were 3-7 days. The average seed yield of mustard was 0.95 t/ha. The highest gross return (Tk.95544/ha) and gross margin (Tk.58210/ha) of the whole pattern were obtained from alternative cropping pattern and that of existing pattern were Tk.47428/ha and the Tk.23415/ha, respectively. The MBCR was 3.61 which showed alternative pattern is more profitable than existing farmers’ cropping pattern.

Program Area: Farming System

Non-commodity: Performance

Objectives:

T to establish improved cropping pattern against farmers’ existing cropping pattern in the Sylhet region.

Methodology:

One alternative cropping pattern T.Aus-T.Aman- Mustard was tested against farmers’ existing cropping pattern T.aus-T.aman-Fallow at FSRD site, Golapgonj, Sylhet during three consecutive years of 1999-2000, 2000-2001 and 2001-2002. The detail agronomic parameters of these two patterns are stated in Table1. For cost and return analysis, the values of the product and by product obtained from different varieties under study were calculated on the basis of prevailing market prices. Owing to good quality, Pajam was sold at a higher price in the market.

Achievement/Findings:

The pattern was initiated with T.aus and transplanting was done on the 18-25 May of different years (Table1). Transplanting time of Aus rice is fully depend on rainfall. Aus sowing is difficult to establish in proper time because of uneven distribution of pre-monsoon rainfall. Delayed transplanting also pushed T.aman in late condition. Results of three consecutive trials during 1999, 2000 and 2001 showed that T.aus of the alternative cropping pattern yielded 5.60,5.82 and 5.42 t/ha, respectively as against 2.14, 2.40 and 2.3 t/ha in existing cropping pattern. The yield of T.aman rice in alternative cropping pattern were 4.90, 3.52 and 5.06 t/ha and that of existing cropping pattern was 3.40, 2.35 and 3.70 t/ha during the year of 1999, 2000 and 2001, respectively. The yields of T.aman in the year 2000 at both the patterns were much lower due to attack by rice hispa. The third crop of the alternative pattern was mustard. In the first two years, the variety use for mustard was improved Tori-7 and 3rd year, it was BARI sarisha-9. Field duration of mustard was 75, 73 and 80 days in 1999-2000, 2000-2001 and 2001-2002, respectively. The turn around times in between T.aman and Mustard were 3-7days. The seed yields of mustard was 0.95, 0.85 and 1.05t/ha in 1999-2000, 2000-2001 and 2001-2002, respectively. whereas in the existing cropping pattern land was fallow during the rabi season. The rainfall occurred in the month of October to November were 342.8, 175.1 and 329.9 mm, and during crop growing period (December to March) it was 170.7, 184.1 and 83 mm in 1999-2000, 2000-2001, and 2001-2002, respectively. Though mustard sowing was late but its yield was comparatively better. The reason might be available soil moisture as well as lower temperature exists during January to March.
