“…It was further revealed that although transplanting methods produced higher filled grains panicle -1 , 1000 grain weight but it was statistically similar to DSR methods (Ali et al, 2014) [3] . Parameshwari et al (2015) [56] observed that no significant differences among different crop establishment methods were noticed in number of grains panicle -1 , panicle length and test weight. Iqbal et al (2017) [32] found that maximum 1000 grain weight was recorded in direct seeded rice followed by transplanted rice.…”

“…Hassan et al (2010) [31] found that transplanted rice reduced the weed population as well as dry matter with higher weed control efficiency resulting in higher grain yield than WSR. Parameshwari et al (2015) [56] observed that the crop establishment methods influenced the weed management practices and improved the weed control efficiency. The highest weed control efficiency of 90.4 and 88.1 per cent were recorded under transplanted and direct seeded rice, respectively.…”

“…According to Kumar et al (2008) direct seeding of sprouted seeds under puddled condition recorded higher growth attributes than other systems of cultivation. Parameshwari et al (2015) [56] observed that the crop establishment methods significantly influenced the plant height at harvest. The taller plants were observed under transplanted rice and it was comparable with SRI.…”

Direct seeding is done by sowing of pre-germinated rice seeds under puddled condition either manually or by drum seeding methods. Direct seeded rice (DSR) cultivation needs only 34 per cent of the total labour requirement and saves 29 per cent of the total cost of the transplanted rice. Weed infestation and competition are severe in direct wet seeded rice as compared to transplanted rice, because of the simultaneous growth of both crops and weeds. Uncontrolled weeds decreased the yield by 96 per cent in dry DSR and 61 per cent in wet DSR. The yield loss due to weeds varies from 40 to 100 per cent in direct seeded rice. Any delay in weeding will lead to increased weed biomass which has a negative correlation with yield. Though manual weeding is considered to be the best, undependable labour availability and escalating labour cost in many cases have given impetus to the development and use of new chemicals for weed control. In contrast to this, chemical weed control offers economic and efficient weed control if applied at proper dose and stage. The combination of chemical, manual and mechanical weed control is an efficient integrated weed management strategy for effective weed control in direct seeded rice.

“…Problems and prospects of rice production in different ecosystems vary greatly (Senthilkumar et al, 2007). Direct seeded rice may involve sowing of pre-germinated seeds in a puddled soil surface (wet-seeding) or into shallow standing water (water-seeding) or dry seeds into a prepared seedbed (dry-seeding) (Parameshwari et al, 2015).…”

Background: Weeds are the major biotic constraint to reduce the rice productivity in direct wet seeded rice. Weed infestation and competition are severe in direct wet seeded rice as compared to transplanted rice, because of the simultaneous growth of both crops and weeds. The yield loss due to weeds varies from 40 to 100 per cent in direct seeded rice. Use of herbicides either singly or in combination with manual or mechanical weeding in puddled direct seeded rice has been highlighted by several workers. Use of alternative herbicides with wide spectrum control of the weeds in direct seeded puddled rice is the need of the present time. The present study aimed to evaluate different weed management practices in direct wet seeded rice under sodic soil.Methods: A field experiment was conducted during Samba season (Rabi) 2016-17. to evaluate the weed management practices in direct wet seeded rice under sodic soil. The treatments comprised of different combination of weed management practices viz., pre emergence, early post emergence herbicides, mechanical weeding and hand weeding twice were tested. Total weed density and weed dry weight, weed control efficiency, yield parameters and yield of rice were recorded. Result: Among the different weed management practices, the lowest total weed density, total weed dry weight and higher WCE, yield attributes, grain and straw yields were registered under application of PE pyrazosulfuron ethyl 25 g/ha fb EPOE bispyribac sodium 25 g/ha. This was followed by application of PE pretilachlor 0.75 kg/ha fb EPOE bispyribac sodium 25 g/ha.

“…However, raising seedling requires additional efforts, nursery materials and capital. On the other hand, the direct seeding is well recognized as a labor and cost-saving cultivation system (Parameswari et al, 2014;Sudhir-Yadav et al, 2014). Especially in tropical regions, this cultivation practice is propagating and being extensively practiced due to the recent introduction of new cultivars and advancement in cultivation techniques (Balasubramanian and Hill, 2002;Farooq et al, 2011;Malabayabas et al, 2014).…”

Direct sowing of rice in a flooded paddy field is a beneficial cultivation practice for water use and labour efficiency, compared to the transplanted cultivation. However, a drastic reduction in seedling emergence under flooded paddy fields is a serious constraint especially when the seeds fell at deeper soil layers. Suitable rice germplasm for the direct sowing in flooded paddy fields could ensure the success of this cultivation practice. Instead of laborious field-based screening systems, a pot-based screening method was adopted for simplicity and efficient evaluation of seedling emergence of a subset of world rice germplasm (n = 75) at different sowing depths. As a result, two rice genotypes, ‘Vary Futsi’ (landrace from Madagascar, non-glutinous, subspecies Indica) and ‘Dahonggu’ (landrace from China, non-glutinous, subspecies Indica), with consistently better seedling emergence were identified from a wide range of rice germplasm. These genotypes could serve as excellent parents for the breeding program in developing new rice cultivars with the improved seedling emergence in flooded paddy fields. There were no significant differences in the seedling emergence rate in flooded paddy conditions among the groups from various agro-geographical regions.
