A study was conducted in farmer’s field through technology demonstrations during Kharif season of 2018 and 2019 in Subarnapur district of Odisha to recommend the most suited short duration drought tolerant upland rice variety particular to the locality. Six different varieties like Sahabhagi dhan, Mandakini, Jogesh, DRR-44, and DRR-42 & Khandagiri were taken with four replications in Randomized Block Design in both years. Technology demonstration included not only the improved short duration varieties, but also a package of good agronomic practices viz. line sowing, seed treatment with Bavistin, proper fertilization with dose @ 80:40:40 NPK/ha, pre emergence herbicide application with pretilachlor, needful manual weeding and  need based plant protection chemicals. The results of demonstration showed that farmers could increase rice productivity notably by adopting improved variety Sahabhagi dhan and DRR-44. These varieties recorded higher grain yields of 64% and 46%, respectively, and fetched a sum return of Rs 25620 and Rs 25275 over farmers’ local variety Khandagiri.

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.

This study investigates the risk behavior of traditional rice variety growers in Erode District of Tamil Nadu state, using Moscardi and De Janvry approach and Discriminant analysis technique. A well structured questioner was prepared and purposive random sampling was done in three blocks which covers highest cultivable area under paddy namely Gobichettipalayam, Modakurichi and Bhavani in Erode district. Each traditional rice varieties have some unique characteristics i.e some are pest and disease resistant, drought resistant, resistant to waterlogged condition and have medicinal values. The present study was done to identify the major risks, to quantify the risk attitude and to identify the factors influencing risk attitude of the traditional variety growers in Erode District. In the research it was found that the varieties preferred by farmers were Thuyamalli, Kichadi samba, Karuppukavuni, Mapillai samba,Arcaud Kichadi Samba, Poongar, Thanga Samba, Sivan Samba and few other varieties they were cultivating in small areas using organic farming method.The major risk found in cultivating traditional rice varieties were market risk followed by human labour risk, processing risk, input risk, technology risk, institutional risk, natural risk and other risks include transport risk and storage risk. The farmers were grouped into three categories i.e., risk preferrers (63.33 per cent), risk neutral (28.33 per cent) and risk averse (8.33 per cent) based on risk attitude. Once again the farmers in each group was categorized into low, medium, high risk based on nine factors namely, farmers age, major occupation, years of schooling, family size, membership in any of the farmers association, proportion of paddy area to total farm area, proportion of paddy income to total farm income, experience and adequacy of market which were influencing the risk attitude of farmers. In order to conserve the traditional rice varieties from extinction, to restore the soil health, to ensure nutritional security the farmers were willing to take risk.

Rice crop is grown in 43934 ha in Chittoor district of Andhra Pradesh during Kharif and Rabi. The traditional medium slender grain cultivar BPT-5204 is most popularly grown variety during Kharif and occupies 30-40 per cent of area in the district, which is susceptible to BPH and blast resulting in low yields and low net returns. Hence, on farm trials were conducted during 2012-13, 2013- 14 and 2014-15 with objective to assess the performance of new rice variety NDLR-7 which is medium slender short duration (130-135d) variety with tolerance to BPH and blast. During all the three years maximum number of BPH/sample was very low in NDLR-7 than BPT 5204 and maximum collections were recorded in November followed by October month. During all the years the variety recorded 6.1t/ha with average net returns of Rs.76,808/- per ha whereas BPT-5204 recorded 5.83t/ha with average net returns of Rs.68,542/ha. Because of its high yield, pest tolerance and good cooking quality it is widely accepted by farmers through horizontal spread of technology. Due to extension activities of KVK, Kalikiri area under NDLR-7 has been increased from 80ha in 2013-14 to 2000 ha in 2016-17 owing to its tolerance to BPH, fine grain and high market price and first choice of farmers, millers and traders.

Abstract To combat the dreaded diseases in rice like bacterial blight and blast, host plant resistance has been advocated as a sustainable method. Through the present study, we have successfully incorporated three major bacterial blight (BB) resistance genes viz., Xa21, xa13 and xa5 into NLR3449, a high yielding, blast resistant, fine-grain type popular rice variety through marker-assisted backcross breeding. Foreground selection was carried out using PCR based, gene-specific markers viz., pTA248 (Xa21), xa13prom (xa13) and xa5FM (xa5) at each generation of backcrossing, while 127 polymorphic SSR markers spanning on 12 chromosomes were used for background selection and backcrossing was limited to two rounds. At BC2F1 generation, a single plant (NLR-87-10) with 89.9% recovery and possessing all the three bacterial blight resistance genes was forwarded to BC2F2 generation. A solitary BC2F2 plant viz., NLR-87-10-106 possessing all the three resistance genes and > 90% genome recovery was identified and advanced through selfing till BC2F4 generation by adopting pedigree method. Three best lines at BC2F4 lines, possessing high level of resistance against bacterial blight and blast and equivalent or superior to NLR 34449 in terms of yield, grain quality and agro-morphological traits have been identified and advanced for multi-location trials.

Climate change issues are affecting the lives and livelihoods of the farming community in our state. With majority of our rural population dependent on farming, the need of the hour is to create awareness among farmers on climate-resilient farm technologies and make them adopt them. So, a study was conducted in the Erumapatty block of Namakkal district of Tamil Nadu to study the awareness and adoption of climate-resilient farm technologies. The findings of this study revealed that majority of the respondents (68.33 per cent) had high level of awareness on climate-resilient farm technologies. With regard to adoption, majority (60.00 per cent) had medium level of adoption on climate-resilient farm technologies. On crop production and protection climate resilient farm technologies, namely drought-resilient varieties, Intercropping, Identification and use of short-duration varieties, drought-resilient fodder crops, Community nursery as a contingency measure for delayed planting, IPDM and PPFM to combat drought condition in small onion majority of the farmers in the study area are aware of it and adopt it in this study area.
