Change Mitigation

Our society faces multiple daunting challenges including finding sustainable solutions towards climate change mitigation; efficient production of food, biofuels, and biomaterials; maximizing land-use efficiency; and enabling a sustainable bioeconomy. Plants can provide environmentally and economically sustainable solutions to these challenges due to their inherent capabilities for photosynthetic capture of atmospheric CO2, allocation of carbon to various organs and partitioning into various chemical forms, including contributions to total soil carbon. In order to enhance crop productivity and optimize chemistry simultaneously in the above- and belowground plant tissues, transformative biosystems design strategies are needed. Concerted research efforts will be required for accelerating the development of plant cultivars, genotypes, or varieties that are cooptimized in the contexts of biomass-derived fuels and/or materials aboveground and enhanced carbon sequestration belowground. Here, we briefly discuss significant knowledge gaps in our process understanding and the potential of synthetic biology in enabling advancements along the fundamental to applied research arc. Ultimately, a convergence of perspectives from academic, industrial, government, and consumer sectors will be needed to realize the potential merits of plant biosystems design for a carbon neutral bioeconomy.

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 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

Oil Palm Industry

5G technology is vital for the development of Internet of Things (IoT) application in Malaysia to enhance the development of the agriculture and plantation industry. The nation is marching towards big data and artificial intelligence. Consequently, having 5G networks merging with IoT technology as a platform would contribute to the country’s gross domestic income up to RM 12.7 billion ringgit. There are tangible and intangible benefits to the oil palm industry if the technologies of 5G/IOT are implemented. In the oil palm industry, the technology of 5G network can uplift the current technology in the field to enhance the labour productivity. On the other hand, the dependency on foreign workers can also be reduced. Apart from that, the use of 5G/IoT will improve crop productivity and land use efficiency to improve palm oil yield. However, IoT platforms relying on 5G technology will be challenging in rural oil palm areas where there is low signal for communication. In relation to that, preliminary research shows that LoRA technology that is similar to 5G technology is able to work in remote areas. 5G/ IoT related technology implementation is vital in the oil palm plantation at the upstream level.

The Hill

A field experiment was conducted at Deurali, Palpa (1200 m asl) during 2004 rainy season to identify the appropriate plant population of maize for increased productivity of maize ginger, net economic return and land use efficiency due to integration of the above crops based cropping system in the hills. Maize was planted as double planting (double plants in a hill with 100x100 cm spacing), single planting (single plant in a hill with 100 x 50 cm spacing), normal planting (75 x 25 cm spacing) and ginger was cropped in between the maize rows at 30 x 30 cm spacing sole maize and sole ginger. The results of the experiment showed that the highest maize and ginger yield were obtained from sole planting system with an average of 6.15 and 41.13t/ha maize ginger and fresh ginger rhizomes respectively. the lowest net return of Rs 16,934/ha was obtained from sole maize planting. Among the intercropping systems. Maize double planting and ginger integration system produced significantly high net income of Rs. 535,426/ha with acceptable land equivalent ration (LER) (1.40). However, the highest net return of Rs 604,034/ ha was obtained from ginger as sole planting. Since maize is the staple food crop in the hill and it could not be ignored in the cropping system, maize double planting with ginger integration was found beneficial with significant high net profit compared to sole maize while ginger gave 12.81% more net profit compared to intercropping. the result of the experiment revealed that double planting of maize with ginger integration system would be profitable instead of sole maize but cultivation of ginger as sole crop has been found much profitable than intercropping in the mid-hills. In the hilly regions farmers generally grow maize and ginger separately. The concept of intercropping maize + ginger in a field enhances crop productivity per unit area. This information which is documented in the maize + ginger in a field enhances crop productivity per unit area. This information which is documented in the different social studies in western hills. <i>Nepal Journal of Science and Technology</i> Vol. 7, 2006

The intention of this review is to place crop albedo biogeoengineering in the wider picture of climate manipulation. Crop biogeoengineering is considered within the context of the long-term modification of the land surface for agriculture over several thousand years. Biogeoengineering is also critiqued in relation to other geoengineering schemes in terms of mitigation power and adherence to social principles for geoengineering. Although its impact is small and regional, crop biogeoengineering could be a useful and inexpensive component of an ensemble of geoengineering schemes to provide temperature mitigation. The method should not detrimentally affect food security and there may even be positive impacts on crop productivity, although more laboratory and field research is required in this area to understand the underlying mechanisms.
