Keywords: Maize  hybrids  ;  winter  season Abstract: National Maize Research Program (NMRP) has initiated research to identify suitable maize hybrids developed by multinational companies for general cultivation as short-tenn strategy using the fund of respective seed company in central and eastern Tarai since last three years. In the process of evaluation, NMRP has assessed 69 and 56 hybrids in 2011 and 2012, respectively from 12 multinational companies in collaboration with RARS, Parwanipur and RARS, Tarahara during winter cropping season along with two OPVs and one hybrid check. The experiment was carried out in randomized complete block design with two replications at both locations in Rice-Maize cropping system and three replications at Rampur in Maize-Maize cropping system. Plot size was four rows of 5 m lengths with 75 em x 25 em (RR x PP) spacing and 160:60:40 kg ha"1 NPK, respectively. Five hybrids from three multinational companies and 11 hybrids from six multinational companies were registered in 2010 and 2011, respectively based on the infonnation provided by the respective seed company. Sixteen hybrids from twelve multinational seed companies were registered in 2012 based on the results of collaborative experiments conducted by National Maize Research Program.

Performance of rice hybrids in spring season in Dhanusha district / Dil Raj Yadav    

Public ISBD in Proceedings of the 27th National Summer Crops Workshop, held at Rampur, Chitawan, 18-20 April 2013, Vol. I / Giri, Y.P.     Title : Performance of rice hybrids in spring season in Dhanusha district Material Type: printed text Authors: Dil Raj Yadav ; Ram Baran Yadaw, Author ; Surya Narayan Sah, Author ; Umesh Sah, Author ; Parmananda Sharma, Author ; Dilip Sah, Author Pagination: 172-173 p. Languages : English (eng) Keywords: rice  hybrids  ;  productive  tillers  grain  yield  panicle  length Abstract: Four rice hybrids were evaluated for yield and yield attributing traits at National Rice Research Program, Hardinath , Dhanusha in comparison to Chaite-2 and Hardinath-1 during spring season, 2011. The experiment was conducted in randomized complete block design with three replications. Out of four tested hybrids two hybrids viz., V -775 and 834 produced more productive tillers/m2 , longer panicles and higher grain yield (kg/ha) than the check varieties Chaite-2 and Hardianth-1. The increase in yield over the checks; Chaite-2 and Hardinath-1 ranged from 20.33-48.13% and 16.73-43.70%, respectively. While the other two hybrids, Arize 6129 and 813 produced lower grain yield (kg/ha) than the checks.

Full season maize varieties research and development for food security and better livelihood of Nepalies hill farmers / Rijal, T.R.    

Public ISBD in Proceedings of the 27th National Summer Crops Workshop, held at Rampur, Chitawan, 18-20 April 2013, Vol. II / Giri, Y.P.     Title : Full season maize varieties research and development for food security and better livelihood of Nepalies hill farmers Material Type: printed text Authors: Rijal, T.R., Editor ; Shrestha, J. ; Koirala, K.B., Author ; Katuwal, R.B., Author ; S Thapa, Author ; N.B Dhami, Author ; A Pokhrel, Author ; Dhakal, J.P., Author ; A.P Paudel, Author ; A Poudel, Author Pagination: 236-261 p. Keywords: OPVs  across  the  locations  ;  hybrids Abstract: Maize is the second important cereal crop in Nepal and staple crop for hill people. Mostly local and contaminated improved varieties are grown in rainfed condition with low yield potential. With the objective of identifying and developing suitable stable stress resistant/tolerant high yielding farmers preferred open pollinated .maize varieties, different genotypes were improved and evaluated in Intermediate Yield. Trial (IYT), Coordinated Varietal Trial (CVT) and Coordinated Farmer's Field Trial (CFFT) in RCB design across hill environments (Pakhribas, Kahre, Khumaltar, Dailekh & Lumle) of Nepal during 2010, 2011 and 2012 summer containing 12, 9 and 6 genotypes respectively. During 2010 summer, the genotypes TLBRS07F16, Resunga Composite and Celaya OOHGYA*HGYB produced significantly highest grain yield in IYT across the locations. In CVT the superior stable genotypes across the locations were OEHPW, RamS04F08 and RamS04F04. Similarly, in CFFT the selected genotypes across the locations were Across9942 /Across9944 and Deuti. The combined result across the locations during 2011 revealed that in IYT the genotypes Manakamana-3, Resunga composite and Rampur S10F18A were superior for grain yield. Genotypes tested across the locations under CVT revealed that TLBRS07F16, CelayaOOHGYA*HGYB and RampurS03F04 were superior to farmer's variety for grain yield and other agronomic traits. Similarly, in CFFT over the locations, TLBRS07Fl6 produced significantly highest grain yield than standard check Manakamana- 3. During 2012, three NMRP developed hybrids were also included in CVT sets across the hill stations. Among the OPVs in CVT, RampurS03F08 and CelayaHGYA *HGYB were significantly superior for grain yield and other agronomic traits and among the hybrids RML-4/RML-17 and RML-32/RML-17 produced more than 8 tlha grain yield across the locations. Similarly genotypes tested under IYT revealed that ZM-401, 07SADVI and TLBRS07FI4 were found significantly superior for grain yield and resistant reaction against foliar diseases. Furthermore, genotypes tested under CFFT showed that Across9942/Across9944, P501SRCOIP502SRCO and Rampur S03F06 produced more than 6 tlha grain yield at farmer's field across the locations.
