Title : Alternate wetting and drying irrigation system: Water saving irrigation option for rice cultivation in Nepal Material Type: printed text Authors: Yadaw, R.B., Author ; A Kumar, Author ; Tripathi, B.P., Author Pagination: 26-31 p. Languages : English (eng) Abstract: Alternate wetting and drying (AWD) trial was conducted at National Rice Research Program (NRRP) Hardinath, during summer season in 2007, 2008 and 2009 to study the performance of rice varieties under AWD system and conventional irrigation system. Significant difference was found for days to heading, maturity and unfilled grains/panicles in 2007 among the tested rice varieties under conventional irrigation system and AWD system in 2007. Highly significant difference for grain yield t/ha, tillers m2 under all irrigation systems was found in 2008………………………………

Title : Collaborative rice research and development thrusts between irri and Nepal Material Type: printed text Authors: Tripathi, B.P., Editor ; Gurung, H.B., Author ; Pandey, Sushil, Author ; Ladha, J.K., Author ; A Kumar, Author ; Regmi, A.P., Author ; Sherchan, D.P., Author ; AK Gautam, Author ; Akhtar, T., Author ; B.B Adhikari, Author ; K.K Dahal, Author ; H.K Panta, Author Publication Date: 2010 Pagination: 203-205 p. Abstract: The three major collaborative projects were initiated from 2005 in different Research Centres of Nepal Agricultural Research
Council (NARC) and in Lamjung site of Institute of Agriculture and Animal Sciences (IAAS), Chitwan. The overall objectives of
these projects are to increase the rice production and productivity in favorable lowlands and marginalized upland rice environments
of both plain and hills ofNepal. Baseline survey of all sites is discussed. Different Integrated Crop Management technologies in ricewheat
systems in both transplanted rice and upland rice evaluated. Farmers' field days' and trainings organized and different
Resource Conservation Technologies (RCTs) evaluated. Both lowland and upland rice varieties were tested in mother and baby
trials. Varieties suitable for both lowlands and upland rice were selected by conducting mother and baby trials as well as in Farmers'
Acceptance Test (FAT) !Minikits and Demonstrations. Farmers have saved seeds of some promising rice varieties s for planting in
the next season. Drought tolerant rice varieties received from IRRI were selected for rainfed lowland conditions of Nepal. For the
dissemination of rice technologies to different stakeholders, exposure trainings/workshops were organized for the scientists/technical
officers/technicians of NARC as well as Subject Matter Specialists (SMS)/Extension Officers of the districts/Training
Officers/Technicians of the Regional Training Centers and Regional seed, soil and plant protection technicians of different regions
of Nepal. Rice Fact Sheets prepared by the scientists were put in NARC website as Nepal Rice Knowledge Bank (NRKB) with the
help of IRRI. Rice technologies prepared by IRRl in the form of Rice Knowledge Bank (RKB) were disseminated by providing COs
to different NARC research stations, district agricultural development offices, regional directorate of agriculture and NGOs working
in rice research and development as well as to IAAS, Rampur for teaching pUiposes. With the establishment ofNepal-IRRI Office,
the technical capability of scientists and technical officers ofNARC has been further strengthened.Link for e-copy: http://elibrary.narc.gov.np/?r=1017 Collaborative rice research and development thrusts between irri and Nepal [printed text] / Tripathi, B.P., Editor ; Gurung, H.B., Author ; Pandey, Sushil, Author ; Ladha, J.K., Author ; A Kumar, Author ; Regmi, A.P., Author ; Sherchan, D.P., Author ; AK Gautam, Author ; Akhtar, T., Author ; B.B Adhikari, Author ; K.K Dahal, Author ; H.K Panta, Author . - 2010 . - 203-205 p.

Title : Participatory Varietal Selection (PVS): An approach to identify superior variety and disseminate quality seed for increased productivity in rainfed lowlands of Nepal Material Type: printed text Authors: Yadaw, R.B., Author ; A Kumar, Author ; Tripathi, B.P., Author ; S Haefle, Author ; Sah, S.N., Author ; S.L. Yadav, Author Pagination: 32-38 p. Languages : English (eng) Abstract: Drought is one of the major constraints to rice production in rainfed areas in the country. In the context of changing climate, increasing irrigation is generally not a viable option for extenuating drought problems in rainfed rice-growing systems. Participatory varietal selection (PVS) trials were carried out to identify drought tolerant rice varieties and distribute their quality seed among farmers to increase rice production in rainfed areas. The statistical analysis showed highly significant differences in grain yield at Sahorwa of Mahottari district and at NRRP in Hardinath in 2009…………………..
