Identifying high yielding protein maize genotypes for hill districts of Nepal / Bhanu Pokhrel    

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 : Identifying high yielding protein maize genotypes for hill districts of Nepal Material Type: printed text Authors: Bhanu Pokhrel ; Jhalak Prasad Dhakal ; Tirtha Rraj Rijal ; Jeeban Shrestha ; Narayan Bahadur Dhami, Author ; Amrit prasad Paudel, Author Pagination: 71-74 p. Languages : English (eng) Keywords: Grain  yield  ;  quality  protein  maize Abstract: Quality protein maize (QPM) varieties are necessary for reducing malnutrition and food security problem in hill districts of Nepal. To identify high yielding QPM varieties, various coordinated varietal trials (CVTs) were conducted in Khumaltar (Lalitpur) and Kabre (Dolakha) from 20 II to 2012 summer season and coordinated farmers' field trials (CFFT) in Lumle (Kaski), Dailekh and Kabre in 20 II summer season and Dailekh and Kabre in 2012 summer season. The genotypic superiority for grain yie ld was determined using ANOV A at 5% level of significance. Overall findings of the trials showed the genotypes namely, Obatanpa followed by S99TLWQ-B and SO I SfYQ produced the highest grain yield in coordinated varietal trials and genotypes S99TL YQ-B followed by SO I SIWQ-3 and Poshilo Makai-1 produced the highest grain yield in coordinated farmers' field trials across testing sites and years. The superior varieties derived from CFFT could be released and recommended to farmers of hill districts ofNepal Link for e-copy: http://elibrary.narc.gov.np/?r=864 in Proceedings of the 27th National Summer Crops Workshop, held at Rampur, Chitawan, 18-20 April 2013, Vol. I / Giri, Y.P.     Identifying high yielding protein maize genotypes for hill districts of Nepal [printed text] / Bhanu Pokhrel ; Jhalak Prasad Dhakal ; Tirtha Rraj Rijal ; Jeeban Shrestha ; Narayan Bahadur Dhami, Author ; Amrit prasad Paudel, Author . - [s.d.] . - 71-74 p.

Weed management study in rainy season maize in Bheri river basin area of Surkhet / Tara bahadur Ghimire    

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 : Weed management study in rainy season maize in Bheri river basin area of Surkhet Material Type: printed text Authors: Tara bahadur Ghimire ; Bhanu Pokhrel, Author ; Jhalak Prasad Dhakal, Author ; Nain Singh Chhetri, Author ; Gam Bahadur Pun, Author ; Anil Pokhrel, Author Pagination: 210-213 p. Languages : English (eng) Keywords: Maize  (Zea  maize)  ;  net  return  weed  flora  control  yield Abstract: Maize (Zea mays L) is the predominant crop in mid-western hills of Nepal. Productivity of maize is low due to several biotic, abiotic and socio-economic factors. Weed infestation is one of the main reasons in lowering the maize yield in this region. To find out the suitable weed contro l measures in hill of mid-western region, a field experiment was conducted in two consecutive years of 20 11 and 2012 at Agriculture Research Station, Dasharathpur, Surkhet. Eleven treatment combinations consisting of Atrazine 50 WP @ 2.5 kg/ha (Pre-emergence), Pendimethaline 30 EC @ 3.3 L/ha (Pre-emergence) and Glyphosate 41 SL 5 L!ha (Postemergence) with or without hoeing; 2,4-D (80%) @ 2 kg!ha (Post-emergence) fo llowed by hoeing; sunhemp mix cro pping (30 kg/ha) and incorporation at 30 days after sowing; hand weed ing without hoeing; farmers practices (hand weedin g and hoeing) and no weeding (control) were evaluated in RCBD with three replications in maize-wheat system under bariland cond itions. Motha (Cyperus sp.), Banso (Axonopus compressus (Swartz)), Bokejhar (Gnaph aliwn purpureum L), ChipleJhar (Pouzolzia zeylanica L.) and Kane jhar (Commelina benghalensis L.) were the predominant weed floras in maize field in bariland cond ition of Bheri river basin area of Surkhet. Atrazine 50 WP @ 2.5 kg/ha (pre -emergence) appli cation and no hoeing treatment resulted the maximum mean grain yield (4205 kg/ha) of maize with highest net return (Rs.5 1600/ha) and benefit cost ratio (2.59). Simi lar ly, sunJ1emp mix cropping and incorporation after 30 days after sowing resulted least weed population up to 60 days after sowing.
