Changes of Reducing Sugar in Potato Genotype During Cold Storage and Their Chips Quality / Mahendra J. Thapa ; M. B. Shrestha ; R. C. Bhandari
Title : Changes of Reducing Sugar in Potato Genotype During Cold Storage and Their Chips Quality Material Type: printed text Authors: Mahendra J. Thapa, Author ; M. B. Shrestha, Author ; R. C. Bhandari, Author Pagination: 241-244 p. Languages : English (eng) Keywords: Potato, genotype, reducing sugar, cold storage, composition, chips Abstract: Potato of five varieties: Kufri Jyoti, Janak Dev, Klwmal Seto, Diseree and Khumal Rato were
evaluated during the cold storage at 5-70c,and obsen•ed the changes of reducing sugar up to
three months (90 days). Tile proximate composition of fresh potato genotypes were analyzed
before storage as moisture content, protein, total ash. total fat, crude fibre and carbohydrate
ranged 78.70 to 81.90%. 1.96 tO 2.29%, 0.82 to 1.09%, 0.04 to 0.10%, 0.41 to 0.58% and 14.61
to 17.56% respectively and found no signi[rcmzt difference in their composition. The level of
redl}cing sugar ranged from 0.12 I 5% to 0.4424% on the fresh weight basis at tlze time of
storage. Tlze score of chips colour was found good in all the varieties of potato before storage.
The level of reducing sugar ranged from 0.9326% to 1.2198%. showed lziglz accumulation of
reducing sugar in all tlze varieties of potato after three months of storage. Tlze chips prepared
from 90 days stored potato were found unacceptable dark brown in colour. Tile level of
reducing sugar in all varieties of potato were found in increasing trend i.e. before storage, 30
days of storage, 60 days of storage and 90 days of storage. The chips prepared from tlze stored
potato of 30 days and 60 days were found withi11 tile acceptable limit except Klzumal Seto.Link for e-copy: http://elibrary.narc.gov.np/?r=504 Changes of Reducing Sugar in Potato Genotype During Cold Storage and Their Chips Quality [printed text] / Mahendra J.

Title : Farmers' Acceptance Situation of Diffused Light Storage Technology for Seed Potatoes in the Hills of Nepal Material Type: printed text Authors: Dhital, B.K., Author Pagination: 221-230 p. Languages : English (eng) Keywords: Diffused light storage, potato store, seed potatoes, storage technology Abstract: A field survey was conducted in September and November 1997 and May 1998 in the Eastem,
Central and We stem hills of Nepal respectively to study the adoption situation of diffused light
storage ( DLS) of seed potatoes and famzers' experiences regarding the DLS technology. The
survey was concentrated in the areas where the DLS was demonstrated previously focusing
011 two dimensions, i.e. (i) adoption of DLS technology by individual farmers or groups of
farmers where a demonstration was made and (ii) the diffusion of the technology around from
its demonstration site. Adoption of DLS technology was clearly a very slow process and took a
long time from initial awareness to the final decision making stage. Overall, tlte adoption of
technology was minimal. Out of 16 Community Seed Potato Stores (CSPS) surveyed, none of
tltem were found successful. The DLS as technology however was adopted mainly in three
sites and 28% of the illlerviewed farmers (79 out of 278) had adopted the technology fully or
partially. Adoption was concentrated near the demonstration sites and it was unlikely to find
the adoption of the technology in areas where it has not been demonstrated. Most adopters did
not make special stntctures for this purpose but used space available in cattle sheds and
farmhoitses instead This paper summarizes the reasons for adoption and non-adoption of the
technology under various environments and discusses its implications for the further
promotion of the technology in Nepal.Link for e-copy: http://elibrary.narc.gov.np/?r=500 Farmers' Acceptance Situation of Diffused Light Storage Technology for Seed Potatoes in the Hills of Nepal [printed text] / Dhital, B.K., Author . - [s.d.] . - 221-230 p.

Title : Planting Materials Seed Systems of Finger Millet, Rice and Taro in Jumla, Kaski and Bara Districts of Nepal Bimal Material Type: printed text Authors: Baniya, B.K., Author ; ,Tiwari, R.K., Author ; Chaudhary, Pashupati, Author ; Shrestha, Surendra K., Author Publication Date: 2005 Article on page: 39-48 p Languages : English (eng) Keywords: Seed flow, seed production, selection, storage, system Abstract: Formal and informal seed supply systems of rice (Jumla, Bara and Kaski), finger millet and taro
(Kaski) were studied in three ecosites of Nepal during 1999-2001 to understand the processes of
seed flow, seed production, seed selection and storage systems. A survey was conducted at 48 to
96 households. Informal seed supply was the only system in Jumla and Kaski and formal system
existed only in Bara. The main sources of seed were farmer’s own saved seed (67-91%), seed
from neighbors and relatives. Exchange of germplasm was the main basis of fulfillment from other
sources. All farmers obtained seed from their own village, while farmers introduced
materials occasionally from outside village. Most of the farmers followed seed selection before
or after crop harvest. Rice field selection and plant selection based on a fixed set of criteria
was the common practice. Non lodged plants with more grain per panicle, bold grains, well-matured
and uniform plants, long panicle, true to type, good looking grains, free from diseases and insects
were the main rice seed selection criteria. All farmers from both sites stored rice seeds by local
methods in the locally available containers. Mor and Mudkothi are the special straw containers to
store rice seed in Bara. Dhara is a special mud structure used to store rice seeds in Jumla. Finger
millet seed supply system was mostly similar to that of rice seed system. Ninety one percent
farmers saved seed for their own use; however, many of them changed finger millet seeds lots or
varieties regularly for their particular plot. Ears selection during harvest by set criteria for
seed purpose was the common practice. Farmers stored finger millet seed carefully in small locally
available containers and tried their best to maintain the quality of seed during different stage of
seed production. Taro has diverse planting materials: cormels, corms with eyes, suckers and corm
with small cormels. Taro planting materials management is totally informal and almost 89% farmers
saved these materials for their use and replaced them mostly after 3 years. Farmers had fixed
criteria of corms and cormels selection for planting purpose and focus and more on disease
free. Storage of planting materials was locally by using local materials and methods.
