Rice (Oryza sativaL.) is a major staple food crop that feeds around 60% of the world’s population. It is a major food crop in terms of production, economy and is grown in all ecological zones of Nepal. In Nepal, traditional method of rice cultivation is widely accepted in which 20-25 days old seedlings are transplanted in the puddled field. Looming water scarcity, water-intensive traditional method of rice cultivation, escalating labour costs pressurize the development of alternative which is highly sustainable and profitable. Direct-seeded rice (DSR) offers a very good opportunity that can cope up the global need and reduces the water use to 50%, labour cost to 60% and increases productivity by 5-10%. It involves sowing of pre-germinated seeds into wet soil surface (wet seeding), dry soil surface (dry seeding) and standing water (water seeding). Weeds are the major constraint in direct-seeded rice (DSR) reducing the crop yield upto 90% and sometimes even crop failure. Enhanced nutrient use efficiency and integrated weed management can produce comparable yields to that of transplanted rice (TPR) encouraging many farmers to switch to DSR. Methane gas emission is significantly lower in DSR than in conventionally tilled puddled transplanted rice mitigating the world’s threat of global warming. Blast disease and root-knot nematode (RKN) are other important problems associated with DSR. Based on the evidences collected, the article reviews integrated package of cultivation technologies associated with DSR, advantages, constraints and likeliness of DSR to be the future of rice cultivation in Nepal.Int.

A large scale demonstration was taken on direct seeded rice in four locations (one at ARS, and three at Farmers field in 50 acres each) in and around the Agricultural Research Station, Dhadesugur, University of Agricultural Sciences, Raichur, Karnataka. Our analysis showed that, the yield performance of direct seeded rice (DSR) varied with transplanted rice (TPR) and with different locations. This may be due to variety used and crop management practices adopted by the farmers. In L2, maximum grain yield was recorded in DSR (6500 kg/ha) and TPR (6200 kg/ ha) compared to other three locations. Further, the grain yield was higher in DSR compared to TPR in all the locations. Similarly, economics of DSR varied with TPR and with different locations. This may be due to yield variation at different locations. In L2, net returns and B:C ratio were higher in DSR (` 93628/ha and 3.93, respectively) and TPR (`79868/ ha and 3.0, respectively) compared to other three locations. Further, net returns and B:C ratio were higher in DSR compared to TPR. Further, 47% of the labour requirement was saved in DSR compared to TPR. Therefore, concluded that, farmers can grow rice by direct seeding instead of planting to save the labour and the expenditure.

Rice cultivation always remains significant for food and livelihood security. The predictions of increasing water deficiency under a changing climate and escalating labor shortages in agriculture have brought a paradigm swing in rice cultivation from conventionally flooded transplanting to direct-seeded rice (DSR). DSR cultivation can potentially address the concerns of diminishing natural resources and mounting production costs in the establishment of transplanted rice. The transition towards DSR saves water, reduces duration to maturity as well as labor required, and reduces negative environmental footprints. Despite all these recompenses, the potential yield losses through enormous weed menaces under DSR remains a challenge and may reduce yield by up to 50%. In this review, we examine the extent of weed infestation, weed shift and the losses in dry DSR (DDSR). Various regional and global scientific efforts made under DDSR have been assessed in the present and the smart weed-management strategies suggested can be adopted after scrutiny. Integration of different weed management approaches, namely prevention, cultural, mechanical, and chemical, have been discussed, which can pave the way for worldwide adoption of DDSR, especially in South Asia. In Asia, 22% of the acreage of total rice cultivation is under DSR and the region-specific integration of these weed-management approaches might reduce herbicide use in these areas by up to 50%.

Direct-seeded rice (DSR) is a possible alternative to conventional puddled transplantedrice, where rice crop is seeded directly in non-puddled fields. The study was conducted toascertain the adoption status of recommended practices of DSR. Personal interviews wereconducted to collect data from randomly selected 210 farmers from three districtsrepresenting different agro-climatic regions of Punjab. Study revealed that selected farmershad adopted DSR on 49.20 per cent of their total area under paddy cultivation. Slightlyhigher number of selected farmers had adopted Tar-Wattar, a new technique of DSR overdry soil method. Only 18.52 per cent respondents had applied first irrigation as perrecommendations of Tar-Wattar method, whereas majority (67.59%) had applied firstirrigation before 21 days. 26.67 per cent farmers had adopted most suitable variety PR-126 and sown it at recommended time. However, in case of other varieties, majority offarmers did not follow recommended time of sowing. A smaller number of farmers haveapplied zinc, iron and sulphur fertilizers to ameliorate micro nutrient deficiencies. Averageyield of others varieties and PR 126 were found to be nearly identical, but due to lessercost of cultivation in DSR as compared to transplanted rice, adopter farmers’ fetched highernet return.

Studies were conducted on the status of insect-pests and natural enemies of direct seeded rice (DSR) in comparison with puddled transplanted rice (PTR) during rabi and kharif in 2013-14. The rice leaf folder and yellow stem required both the seasons. Maximum leaf folder Cnaphalocrocis medinalis (Guenee) (13.03%) damage and yellow stem borer damage (13.49%) of white ears was recorded during last week of October and second week of November in DSR under unprotected situation respectively. While sucking pests population mainly green leafhopper incidence was comparatively high in PTR (3.29 and 4.92/hill) also plant hoppers incidence (BPH and WBPH) (28.90 and 18.44 adults/hill) under unprotected situation during two seasons respectively. Population of predators at both the season remained high throughout the study period in PTR than the DSR except
