Under irrigated condition, double transplanting (DT) of Boro rice in a T. Aman-Potato-Boro cropping pattern may be an alternative option either to reduce the yield loss of late planted Boro rice or to keep it at a minimum level. An experiment was conducted during 2003 - 2006 at Gazipur and Kapasia with three cropping patterns. The patterns were: T. Aman- Boro- Fallow (CP1), T. Aman-Potato- Boro (CP2) and T. Aman- Potato- double transplanted (DT) Boro (CP3). Rice varieties were BRRI dhan44 and BRRI dhan29 for Aman and Boro seasons, respectively; while Diamont was the potato variety. Rice equivalent yields (REY) in CP2 and CP3 were 82 and 109% higher than that in CP1 at Gazipur, whereas those were 122 and 179% higher at Kapasia. The increase of REY in CP2 was attributed to higher potato yield and that in CP3 was due to higher yield of potato and Boro rice. Double transplanting of Boro in CP3 facilitated greater yield of potato and realized almost similar yield of Boro that was obtained in CP1. Economic analysis showed that the gross margin was the highest in CP3 (US$ 1797 and 2720 at Gazipur and Kapasia, respectively). CP3 may be recommended for medium high lands of Bangladesh and other Asian rice growing countries.

Increasing system productivity in a planned way is an important base for attaining food security, where bringing marginal land like Charland under intensive crop cultivation is highly desirable. The field trial was conducted in the Charland of the Jamuna River under Saghataupazilla of Gaibandha during 2017- 18 & 2018-19 to increase the productivity and profitability through the development of three crops-based improved cropping patterns instead of the local practice (double-crop). Three crops based improved cropping pattern namely Millet (BARI Kaon-2)-Jute (O-9897)-T. Aman (Gainja) was compared with the existing cropping pattern of Millet (Local)-Fallow-T. Aman (Gainja). The experiment was laid out in six dispersed replications maintaining RCB design. The introduced improved cropping pattern produced the higher system productivity based on rice equivalent yield, REY (12.95 t ha-1), than the existing cropping pattern (4.20 t ha-1), which is three times higher than the existing pattern. Total field duration and turnaround time were 323 and 42 days, respectively in improved pattern and 215 and 150 days, respectively in the existing pattern, which revealed that 108 days more could be made productive through the introduction of improved cropping pattern. The alternate pattern increased production efficiency and land-use efficiency by 35% and 30%, respectively than that of the existing cropping system. The gross margin was also three times higher in the improved cropping pattern (1, 41,600 Tk ha-1 yr-1) compared to the farmers’ existing cropping pattern (38,350 Tk ha-1 yr-1). The marginal benefit-cost ratio (MBCR) was calculated 2.44 in an improved cropping pattern over the existing cropping pattern. The inclusion of an extra one crop (Jute) in the existing cropping pattern and replacement of the local millet variety by high yielding variety (BARI Kaon-2) could play a significant role to increase the system productivity as well as profitability in the Charland of Saghata, Gaibandha.

Boro Rice

Cropping systems in the Level Barind Tract (LBT) of Bangladesh are highly diverse, as Transplanted (T.) Aman and Boro (T. Boro) rice are a common practice in the area. Although. T. Aman is generally cultivated in the rainy (monsoon) season, but the T. Boro rice is the intensive irrigation-based winter rice with high establishment costs as a result of exhaustive tillage and high labours for transplanting of seedlings. Furthermore, pumping of a large amount of irrigation during T. Boro cultivation declines the level of groundwater, which is not environmentally friendly nor cost-effective. Therefore, the replacement of the T. Boro rice from the cropping pattern in the LBT area is the major concern of policymakers. In this context, a replicated three to four crop-based cropping systems (CS) field trial was conducted in LBT of Gaibandha, Bangladesh for consecutive three years (2018–2020) to evaluate productivity, profitability and sustainability of the multiple crop-based cropping systems. Among these CS, existing three crops based CS, CS1: T. Aman–Potato–T. Boro (introduction of the local potato in the existing cropping system) were compared with four crops based CS2: T. Aman–Potato–Cucumber–T. Aus (Introduction of high yielding potato, cucumber and T. Aus as an improved cropping system). After two years of observations, significantly higher system productivity (rice equivalent yield; REY) was found in the improved CS2 than that of existing CS1 in both years (two years’ average 49% or 11.1 t ha−1). As a result of the introduction of the high yielding potato, cucumber and T. Aus rice instead of the T. Boro rice. The CS2 was also found profitable as compared to the CS1 in terms of higher gross margin (by 74%), net return (double) and benefit-cost ratio (BCR) (1.69 vs. 1.44) due to higher gross return with slightly higher (by 28%) production cost. It is due to farmers received higher prices for potato, cucumber and two rice crops in the improved CS2 than the existing CS1. On the other hand, protein and energy output was lower (by 17% and 9%, respectively) in the CS2 than the existing CS1, due to the less content of protein and energy value in the vegetable cucumber. The results of the study revealed that crops diversification in the existing T. Boro based CS with high yielding potato, cucumber, and T. Aus rice, improved the system productivity, profitability and sustainability; which lead to improve the food security of the increasing population and also reduce the adverse effect on the environment.

A field trial was conducted at the Regional Wheat Research Centre of Bangladesh Agricultural Research Institute (BARI), Rajshahi to study the comparative agronomic performance and economic return of four crops based cropping patterns. The cropping patterns were as follows: CP1= Transplanted Aman rice (cv. Binadhan-7)–Mustard (cv. BARI Sarisha14)–Boro rice (cv. BRRI dhan28) – Transplanted Aus rice (cv. Parija); CP2= T. Aman rice–Potato (cv. Diamont)–Boro rice–T.Aus rice; CP3=T. Aman rice–Mustard (cv. BARI Sarisha15)–Mungbean (cv. BARI Mung 6) –T. Aus rice and CP4 = T. Aman rice–Fallow–Boro rice–Fallow (Control). The results showed that four crops could be grown successfully one after another in a sequence in the field with three crops patterns.  The highest rice equivalent yield (REY) 25.62 t ha-1 was obtained from the cropping pattern CP2 (T. Aman rice–Potato–Boro rice–T.Aus rice) and it was followed by CP1 (18.49) and CP3 (16.03) during one year crops cycle. The highest gross margin Tk. 148882 ha-1 was also obtained from CP2  followed by CP3 (Tk. 133315 ha-1). The highest MBCR (2.24) was however, obtained from the cropping pattern CP3 (T. Aman–Mustard– Mungbean–T. Aus).  Based on overall yield performance, economic benefit and climatic situation of Rajshahi region it may be concluded that CP3 was the best pattern than others.Bangladesh Agron.

Field experiments were conducted during 2007-2010 to evaluate the agro-economic productivity of BRRI Aman rice varieties and Rabi vegetables at the Bangladesh Rice Research Institute (BRRI) in silty clay loam soil. Five Aman rice varieties having different growth durations and three winter vegetables viz., tomato, red amaranth and bush bean were evaluated in split plot design with three replications. Mungbean was grown in Kharif-I season. Rice varieties did not differ significantly in terms of grain yield (t ha-1). Among the three vegetables, the yields of tomato, red amaranth and bush bean were 35.02, 7.53 and 4.33 t ha-1, respectively. Average yield of Mungbean was 0.89 t ha-1. In case of rice equivalent yield (REY), Tomato-Mungbean-BRRI dhan33 cropping pattern produced comparatively high average REY (29.95 t ha-1) followed by Tomato-Mungbean-BRRI dhan39 (27.33 t ha-1) cropping pattern. Among the tested cropping patterns, Tomato-Mungbean-BRRI dhan33 and Tomato-Mungbean-BRRI dhan39 were more profitable than other patterns.

A field experiment was conducted at multi-location testing (MLT) site, Barura under On-Farm Research Division (OFRD), Bangladesh Agricultural Research Institute, Cumilla during 2014-16 to determine the productivity and profitability of cropping patterns, viz. Boro (var. BRRI dhan28)-T.Aus (var. BRRI dhan48)- T. Aman (var. BRRI dhan49)-Fallow (existing cropping pattern) and Boro (var. BRRI dhan28)-T. Aus (var. BRRI dhan48)-T. Aman (var. Binadhan-11)-Mustard (var. BARI Sarisha-14) as  improved cropping pattern. The results showed that improved cropping pattern provided higher amount of grain and by-product yield. The highest mean REY (18.08 t ha-1), PE (54.61 kg ha-1 day-1), LUE (90.68 %) and SYI (77.12%) was obtained from improved cropping pattern Boro-T.Aus-T. Aman-Mustard and the lowest (14.30 t ha-1 in 2014-15 and 13.98 t ha-1 in 2015-16) from farmers existing cropping pattern. The highest gross return (Tk. 274800 ha-1 in 2014-15 and Tk. 276600 ha-1 in 2015-16), gross margin (Tk. 113950 ha-1 in 2014-15 and Tk. 106750 ha-1 in 2015-16) and BCR (1.70 in 2014-15 and 1.66 in 2015-16) were obtained from improved four crops based cropping pattern (Boro-T. Aus-T. Aman-Mustard). Two years results showed that four crops could be grown one after another in a sequence in the farmers field of Cumilla region for achieving higher system productivity and economic return.

An experiment was conducted to develop a culture system for producing brackishwater shrimp, Penaeus monodon, at a management strategy affordable for marginal to medium farmers. Shrimp was produced by two cropping patterns viz., short cycle (60 days) double crops and long cycle (120 days) single crop each at three stocking densities viz., 3, 5, 7 nos./m2. The analysis of results revealed that production of shrimp of 913.57 - 1429.38 kg/ha in long cycle single crop was higher than that of 804.42 - 1296.87 kg/ha in aggregate of short cycle double crops at 3 - 5 nos./m2 density, but at 7 nos./m2 density, production of shrimp of 1899.39 kg/ha was higher in short cycle double crops than that of 1857.31 kg/ha in long cycle single crop. The differences in production between two cropping patterns at different densities were not significant. Gross margin was higher in high stocking ponds in both short and long cycle cropping pattern and it was 1.75 - 2.24 times higher in long cycle culture than that short cycle culture. However, considering higher benefit cost ratio and requirement of supply of oxygen for the production management, it can be surmised that production of shrimp in short cycle double crops at 5 nos./m2 densities will be better affordable for marginal to medium farmers having limited resource.Bangladesh J.

The trial was conducted at Multi Location Testing (MLT) site under On-Farm Research Division, BARI, Kushtia during the last week of February, 2015 to second week of February, 2017 at farmers’ field condition to find out the productivity and profitability of three alternate cropping patterns, i.e. ACP1=Mustard (var: BARI Sarisha-15) - Mungbean (var: BARI Mung-6) - T. Aus rice (var: BRRI dhan48) - T. Aman rice (var: Binadhan-7), ACP2=Lentil (var: BARI Masur-6) - Mungbean (var: BARI Mung-6) - T. Aus rice (var: BRRI dhan48) - T. Aman rice (var:Binadhan-7), ACP3=Wheat (var: BARI Gom-28) - Mungbean (var: BARI Mung-6) - T. Aus rice (var: BRRI dhan48) - T. Aman rice (var:Binadhan-7) against the existing cropping pattern, i.e. ECP= Lentil (var: BARI Mashur-6) – Sesame (BARI Teel-3) - T. Aman (var: Binadhan-7). Findings revealed that the required mean crop durations ranged 340-356 days for one cycle in a year in four crops based cropping patterns against 293 days in existing cropping pattern. Total seed/grain yields in terms of REY of ACP1, ACP2, and ACP3 were 14.85, 16.06 and 14.92 t ha-1 year-1, respectively which were 44%, 56% and 45%, respectively higher than that of existing pattern (10.30 t ha-1 year-1). Mean production efficiency (32.53-40.43 kg ha-1day-1), land use efficiency (93.15-97.53%) and mean gross margin ( Tk. 109393 - Tk. 127834 ha-1) of all alternate cropping patterns were higher than that of existing cropping pattern (PE: 23.63 kg ha-1day-1, LUE: 80.28% and gross margin Tk. 94929 ha-1). As a result, all alternate cropping patterns were agronomically feasible and economically profitable. Among the alternate cropping patterns, ACP2=Lentil (var: BARI Masur-6) - Mungbean (var: BARI Mung-6) - T. Aus rice (var: BRRI dhan48) - T. Aman rice (var: Binadhan-7) performed the best. Therefore, farmers in Kushtia area of Bangladesh might follow the alternate cropping patterns in high and medium high land for higher crop productivity and profitability over existing cropping pattern.

The study was carried out at Multi Location Testing site, Sujanagar, Pabna during two consecutive years of 2011-12 and 2012-13 growing season to assess the performance of the pattern with newly released crop varieties against the existing one usually practiced by the farmers with traditional varieties in order to increase yield and economic return. The experiment was laid out in a randomized complete block design with six dispersed replications at farmer’s field. In improved pattern (IP) BARI Gom-26, BARI Til-4 and Binadhan-7 variety were used for wheat, sesame and T. aman rice, respectively. On the contrary in existing pattern (EP) farmers usually use BARI Gom-21, local (char shira) and Sharna cultivar for wheat, sesame and T. aman rice, respectively. The mean yield was recorded 4.66, 1.34 and 4.79 t ha-1 from wheat (BARI Gom-26), sesame (BARI Til-4) and T. aman (Binadhan-7) respectively from the improved cropping pattern whereas average yield 3.81, 0.98 and 4.58 t ha-1 was obtained from wheat (BARI Gom-21), sesame (local) and T. aman (Sharna), respectively from the existing pattern. Two years mean data also showed that improved pattern provided about 18% higher REY compared to existing pattern. Sustainable yield index and production efficiency were also found maximum with improved cropping pattern. Similarly, maximum gross margin and benefit cost ratio were obtained from improved cropping pattern. Bangladesh Agron. J. 2018, 21(2): 13-18

The experiment was conducted at Kushtia Sadar, Bheramara and Gangni Multi Location Testing (MLT) sites under On-Farm Research Division (OFRD), BARI, Kushtia (AEZ 11) during the last week of July to second week of May for three consecutive years (2013- 14, 2014-15 and 2015-16) to develop alternate cropping pattern (Mustard-Boro -T.Aman) and to compare its productivity and profitability against farmer’s existing cropping pattern (Fallow - Boro-T.Aman). The mustard (var: BARI Sarisha-14), Boro rice (var: BRRI dhan28) and T.Aman (var: Binadhan-7) were used in alternate cropping pattern, while BRRI dhan28 for Boro rice and BRRI dhan39/Sorna for T.Aman rice were used in the existing cropping pattern. Findings revealed that the mean crop duration of alternate cropping pattern ranged 269-287 days by inclusion of mustard. Rice equvalent yield of alternate cropping pattern was 13.98 t ha-1 year-1 which was 34% higher than that of existing pattern (10.47 t ha-1 year-1). Land use efficiency (76.44%) and labour employment (441 mandays ha-1 year-1) of alternate cropping pattern were 33 and 26%, higher, respectively than those of existing cropping pattern. The mean gross return (Tk. 2,53,960 ha-1) and gross margin (Tk. 99,513/ha) of alternate cropping pattern were 29 and 32%, respectively higher compared to those of existing cropping pattern (Gross return: Tk. 1,97,346 ha-1 and Gross margin: Tk. 75,340 ha-1) due to inclusion of high yielding variety of mustard. Therefore, farmers in Kushtia region of Bangladesh could follow alternate cropping pattern in their high and medium high land where lands remain fallow after harvesting of T. Aman rice for higher crop productivity and profitability. Bangladesh J. Agril. Res. 44(1): 69-78, March 2019
