“…Tiller density at 35 DAT had higher than at flowering and it was due to some tiller mortality after panicle formation. Similar results were reported by Hasanuzzaman et al, 2009;Sudhir-Yadav et al, 2011. Tiller density was higher when plots received nitrogen source of 50% cowdung + 50% prilled urea with season long weed-free.…”

A field study was conducted at the Agronomy research field of Bangladesh Agricultural University, Mymensingh, during the period of July to December, 2013 to evaluate the sources of nitrogen and weed management options on weed growth and rice yield. The experiment included four nitrogen sources (100% cowdung, 100% prilled urea, 100% urea super granule, 50% cowdung + 50% prilled urea) and four weed management options (weedy, application of herbicide at 3 DAT, application of herbicide at 3 DAT followed by hand weeding at 21 DAT and weed free) . Sources of nitrogen and weed management options had significant effect on tiller number, biomass, SPAD value, panicle number, number of florets panicle -1 , grain and straw yield, and weed biomass. The highest grain yield (5.40 t ha -1 ) was found in the treatment of 50% cowdung + 50% prilled urea with combination of season long weed free. Although 100% prilled urea had significantly similar grain yield to 50% cowdung + 50% prilled urea, however, across the weed management options, 100% urea super granule and 100% cowdung had 15 and 27% lower grain yield. Irrespective of the weed management options, 100% prilled urea had always higher weed biomass and 100% USG, 50% cowdung + 50% prilled urea, and 100% cowdung had 46, 35 and 19% lower weed biomass, respectively, compared with 100% prilled urea. In terms of rice yield and weed management, combined application of organic and inorganic source of nitrogen is better than only chemical or only organic source and pre-emergence herbicide followed by one hand weeding for transplanted aman rice.

“…Slightly lower but significantly similar grain yield was recorded from the reduced and strip tillage DSR (Figure 2). From many previous studies, it is found that yield of DSR and PTR almost similar if managed well [8,9] lower yield was also recorded from many previous studies where weeds were not managed well [10,11]. Some studies in DSR reported higher yield in strip tillage condition than reduced tillage where weed pressure was very low [2].…”

High labor wage and irrigation water scarcity are the major constraints to becoming rice production less profitable and unsustainable in Bangladesh. To address these problems, rice production needed less water and less labor consuming production technologies. In traditional rice production systems which is puddled-transplanted rice (PTR), a significant amount of water and labor are used for tillage (wet) and transplanting operations.A farmers' participatory on-farm trial was conducted to evaluate the performance of aus rice at different tillage systems and crop establishment methods in the southern part of Bangladesh. Wet tillage (puddled systems) to dry-tillage and transplanted rice to direct dry-seeded rice (DSR) may have the potential to reduce production cost by using less labor and water, resulting in higher profit. The trial examined tillage systems (strip tillage, reduced tillage and puddling) and crop establishment methods (direct dry-seeded and transplanted) in six farmers' fields in aus 2015.Crop established by reduced-and strip-tillage in DSR conditions reduced crop duration by 7 days compared to PTR. Grain yield (4.4-4.6 t ha -1 ) was similar in DSR which is established by reduced-and strip-tillage conditions and PTR; however, total production cost in DSR was 15-18% lower than the PTR. Slightly higher but significantly similar gross income was recorded in PTR than DSR, however, net profit was significantly lower in PTR and it was due to higher production cost involvement. DSR has the potentiality of similar yield to PTR and reduces production cost which increases the net profit of rice production.

“…However, grain yield is less stable in aerobic culture than in conventional flooded culture, mainly owing to a smaller spikelet number per unit area and a smaller single-grain weight Kato et al, 2006;Peng et al, 2006;Matsuo and Mochizuki, 2009;Sudhir-Yadav et al, 2011). Kato and Katsura (2010) showed that the spikelet number per unit area in aerobic rice culture was determined by biomass production during the late reproductive period and by nitrogen uptake until 2 weeks before heading, as was shown by Yoshida et al (2006) in rice plants grown in flooded culture.…”

“…Aerobic rice culture, in which rice is grown in non-puddled soil under aerobic conditions, is a rice production system that requires less water than conventional flooded rice culture (Humphreys et al, 2010). In addition, aerobic rice culture is particularly productive when used with high-yielding cultivars and adequate crop management (George et al, 2002;Kato et al, 2009;Sudhir-Yadav et al, 2011). Thus, aerobic rice culture is a promising rice production system that can both save water and achieve high yields.…”
