Title : Agronomical investigation of drought tolerant rice in Mid Western Terai of Nepal Material Type: printed text Authors: Mishra, K.K., Author ; Thapa D.B, Author Pagination: 39-47 p. Languages : English (eng) Abstract: Field experiments were conducted during rainy season of 2008 and 2009 at Regional Agriculture Research Station, Khajura, Banke to find out nutrient use efficiency and seedling age effect of different rice genotypes. Grain yield obtained at 45:30:20 kg N:P2:O5:K2O/ha was significantly superior over control and at par with 90:60:40 kg N:P2:O5:K2O/ha. Interaction between nutrients levels and rice genotypes on grain yield was significant. Rice genotypes impacted rice grain yield when averaged over the nutrients levels……………………..

Title : Genetic Parameters of Common Wheat in Nepal Material Type: printed text Authors: B.K Joshi, Author ; Thapa D.B, Author ; Bhatta, M.R., Author Publication Date: 2015 Article on page: 9-13p. Languages : English (eng) Keywords: Covariance components, genetic parameters, Triticum aestivum, variance components Abstract: Knowledge on variation within traits and their genetics are prerequisites in crop improvement program. Thus, in present paper we aimed to estimate genetic and environmental indices of common wheat genotypes. For the purpose, eight quantitative traits were measured from 30 wheat genotypes, which were in randomized complete block design with 3 replicates. Components of variance and covariance were estimated along with heritability, genetic gain, realized heritability, coheritability and correlated response. Differences between phenotypic and genotypic variances in heading days, maturity days and plant height were not large. Grain yield and plant height showed the highest phenotypic (18.189%) and genotypic (12.06%) coefficient of variances, respectively. Phenotypic covariance was higher than genotypic and environmental covariance in most of the traits. The highest heritability and realized heritability were of heading days followed by maturity days. Genetic gain for plant height was the highest. Co-heritability of 1000-grain weight with tillers number was the highest. The highest correlated response was expressed by grain yield with tillers number. This study indicates the possibility of improving wheat genotypes through selection utilizing existing variation in these traits.

Title : Livestock farmer's group extension approach: an experience of central development region of Nepal. Material Type: printed text Authors: Thapa D.B, Editor Publisher: Lalitpur : NASA Publication Date: 1992 Pagination: 119-124 p. General note: AN: 3051 Keywords: Animal production; Extension activities; Pastures; animals;Oat (Avena sativa L.) & legumes, Nitrogen fertilizer, Rainfed condition, Green yield. Class number: NR-4416 Abstract: Livestock is an integral part of agriculture in Nepal . It has significant role in the Nepal's economy. In 1984/85, it has contributed about 17% of the total gross domestic product (GDP) in the form of milk, meat, egg, ghee, woo hides and skin, and 28% in the total agricultural GDP. About 20% of the total cattle population and 1% of the buffalo population are unproductive. Besides, the livestock consumes most of its energy in the search of food for maintenances than to production. The improved methods of livestock raising adopted in Nepal are, animal health, breeding, nutrition and management practices.

Title : Major achievements of stem and yellow rust research on wheat in Hills of Nepal Material Type: printed text Authors: Sharma, S., Author ; A Mudwari, Author ; Thapa D.B, Author ; Bhatta, M.R., Author ; Bhandari, D., Author ; S Joshi, Author ; Baidya, S., Author ; A.K Joshi, Author Pagination: 307-313 p. Languages : English (eng) Keywords: Cultivars, Yello Rust, UG 99 Abstract: Resistant genotypes and cultivars against Ug99 and yellow rust were scaled up and promoted in farmers fields for increased genetic diversity, Elite genotypes identified resistant were BL3503, BL323S, WKl 182, WK1481, NL971, WK1023, BL2879, BL2739 and BL2818. The genotypes WK1444, WK1581, BL3128 WK1023, WK1320, BL3587 and NL1004 recorded seedling susceptibility and adult plant resistance. The cultivar, WK 1204 released as yellow rust resistant is preferred by farmers and has increased coverage. Pasang Lahmu is liked mostly at Ratnechur of Myagdi district and is still showing durable resistance to yellow rust............
