In eastern India, more than 13.0 million ha of rice lands are affected by excess water and periodically suffer from flash floods and complete submergence. Most of the traditional and adapted rice varieties of this situation are low yielders. To overcome these problems the high yielding rice variety (HYV), Rajdeep (IET 17713) has been developed by Rice Research Station, Government of West Bengal, Chinsurah, Hooghly as high yielding rice variety for semideep water situation. Field experiment was conducted to evaluate the performance of promising semideep water rice (Oryza sativa L.) genotypes under lowland situation during wet season of 2002-2013. Performance of Rajdeep, semideep water rice was better and therefore it was released. It is tolerant to sheath blight, sheath rot diseases and stem borer, leaf folder insect-pests. The high yielding semideep rice variety, Rajdeep exhibited superiority over national check (Sabita), regional check (Purnendu) and local check tested in different locations under All India Coordinated Rice Improvement Project (AICRIP) trials during kharif, 2002-2003 conducted by ICAR-Indian Institute of Rice Research, Hyderabed, India. This variety was also tested in multi-locational yield trials (2003-2013) along with check variety Swarna-Sub 1/ Bhudeb at different locations of West Bengal. After testing at national level as well as at state level, based on yield performance of the variety, the HYV semideep rice variety Rajdeep was released and notified by Government of India in the Gazette of India vide Notification No. S.O. 1007(E) on 30th March, 2017.

Disease surveys were conducted in rice grown districts of Libokemkem, Dera and Fogera in south Gondar zone in 2016 and 2017 cropping seasons. The study was designed to identify and record rice disease flora, their distribution in the districts, prioritize according to the importance and document for future use. Forty-six and 48 rice fields were assessed from nine Peasant Association (PA) in 2016 and 2017 cropping seasons, respectively. Rice diseases; Leaf blast, Panicle Blast, Brown spot, Sheath rot, Sheath brown rot, Sheath Blight, Bacterial blight, Rice Yellow Motile Virus, Kernel smut, Downy mildew were identified in 2016 cropping season and nine rice diseases: Leaf blast, Panicle Blast, Neck Blast, Node blast, Brown spot, Sheath rot, Sheath brown rot, Rice Yellow Motile Virus, Kernel smut were identified in 2017. The overall mean prevalence of sheath rot and sheath brown rot diseases were above 60%, while the others had prevalence below 21%. The incidences and severities of these two diseases were higher than the other diseases implying that both diseases were important. In the present studies many rice diseases were recorded in lowland ecosystem as compared to upland ecosystem. From the assessment X-jigna cultivar was more susceptible to rice disease and followed by Gumera. The results indicate that a sheath rot, and sheath brown rot, were important across the districts and years. Loss assessment studies should be initiated in order to know the yield damage caused by the diseases.

A basic IPM module for basmati rice as a part of integrated crop management accounting the pest prevalence and the information available from literature has been developed. As the module is location specific and dynamic, therefore needs regular updating and fine tuning depending on the location and pest prevalence. The technology has been successfully validated and implemented during 1998 to 2019 in Pusa Basmati 1, Taraori Basmati, Dehraduni Basmati, Pusa Basmati 1121 in Haryana, Uttar Pradesh and Uttarakhand with little modification and fine tuning. Implementation of the technology resulted in increase in rice grain yield i.e., 21.6% in Pusa Basmati 1 at Shikohpur, in Uttar Pradesh 21.5% in Taraori Basmati at Chhajpur in Haryana, 19.5% in Type 3 in Uttarakhand, 14.5 to 22.7% in Pusa Basmati 1121 in Haryana and 38.2% in Pusa Basmati 1121 in Uttar Pradesh over farmer's practices (FP). In all the basmati rice trials, higher yield as well as Benefit - Cost (B-C) ratio was obtained in IPM as compared to FP. Implementation of IPM led to significant reduction in uses of chemical pesticides. In case of IPM, only 1.46 application of chemical pesticides (103.2 g a.i./ha) were undertaken in Pusa Basmati 1121 against 2.8 application in FP (1214.4 g a.i./ha) at Bambawad, Uttar Pradesh. ICAR-NRRI, Cuttack developed and validated IPM module at Sigmapur (Cuttack, Odisha) non-Basmati rice variety Pooja for four kharif seasons i.e 2010-2013 using standard agronomic practices. The trial resulted in an enhancement of 47.1% yield and 26.47 % B-C ratio over FP. Additional income of Rs. 9857/- per ha was also obtained in IPM over FP. On-Farm trial on validation of IPM module in non-Basmati rice (Pooja variety) under semi deep water conditions conducted in 10 ha during rabi 2017 at Nagapur and Basudeipur villages in Khurda district of Odisha resulted in reduction in the incidence of insect pests and diseases with higher population of natural enemies as compared to FP. Rice yield was recorded 5600 kg ha-1 in IPM as against 4900 kg ha-1 in FP. Recently, ICT based e-pest monitoring and advisory has become an important component for area wise implementation of IPM at state and national level. The programme has been successfully implemented in Odisha during 2010 and 2011 under RKVY. Implementation of the programme had resulted successful management of swarming caterpillar in 13 rice growing districts of Odisha during kharif 2010 and 2011.

Abstract For crop production to cope with problems driven by climate change, such as salinity, drought and extreme temperatures, the Bangladesh Institute of Nuclear Agriculture (BINA) released a late Boro rice variety, 'Binadhan-14' in 2013 which is tolerant to high temperature, has short duration (105-115 days) and gives average yield of 6.9 t/ha. This variety was developed by irradiating the seeds of 'Ashfal', a local salt-tolerant landrace of rice, with 200 Gy of carbon-ion beams. The late-transplanting potential of this variety also helps in avoiding seedling injury due to severe cold. Another variety, 'Binadhan-19', was developed by irradiating the seeds of 'NERICA-10' rice with 40 Gy of carbon-ion beams. This was released by the National Seed Board of Bangladesh (NSB) in 2017 as a drought-tolerant, short-duration (95-105 days) and high-yielding (average 4.0 t/ha) variety for the Aus growing season. BINA developed a salt-tolerant wheat variety, 'Binagom-1', by selecting from a segregating population, obtained from NIAB, Pakistan. This variety was released in 2016; it can tolerate salinity (up to 12 dS/m) and produces an average yield of 2.8 t/ha. Apart from these, BINA developed four salt-tolerant groundnut varieties ('Binachinabadam-5', 'Binachinabadam-6', 'Binachinabadam-7' and 'Binachinabadam-9') by irradiation with gamma-rays. All these four varieties can tolerate salinity (up to 8 dS/m) from flowering to maturity and produce pods at 1.8-3.4 t/ha under saline soil conditions. These climate-resilient varieties are playing a significant role in food security and enhancing the nutritional status of the people of Bangladesh.
