Title : Minimization of broken ratio in sequent process of rice shelling and milling. Material Type: printed text Authors: Bhandari, R.C. ; Mahendra J. Thapa, Author ; Man B. Shrestha ; Eiji Bekki, Author Publisher: Khumaltar : Food Research Unit Publication Date: 2004 Pagination: 1-18 .p Keywords: Post harvest technology; Rice; Foods;Sheller, Polisher, Crack ratio, Broken Polishing, Milling recovery Abstract: Shelling and milling experiments were carried out with nine combinations of three types(Rubber-rolls, Centrifugal impeller and Rubber and Steel-rolls) test sheller and two types(Frictional and Emery abrasive) test whitener and polisher in 28 varieties of paddycollected from Terai Plane, Mid-hill, and High-hill (mountain) respectively. From theresults, it was found that there were striking differences in broken ratio among thesevarieties. The fact obtained is considered as one of necessary references when a newvariety will be adopted or accepted in near future. The variety, which is easy to causebreakage, should be avoid to release and take care never to mix with another variety. Thewhole grains having the crack since beginning of harvest will cause broken after shellingand subsequent milling. Long size-slender shaped grain had higher crack ratio than theshort size-bold shaped grain before shelling. Accordingly, the shelling and millinginstruments should be selected and combined with such a type as makes suitable for grainsize-shape. The appropriate grain moisture for shelling and milling is under 14%. Over - dry grain cause formation of cracking in a sound grain A rubber-rolls type sheller(Satake)showed the lowest broken ratio after shelling, however, final broken ratio aftersubsequent milling changed to the highest broken ratio only in milling irrespective ofusing any milling instruments. A centrifugal impeller type sheller(Ohtake) showed thehighest broken ratio after shelling and final broken ratio changed to the lowest one only inmilling. The proportion of each broken occurrence was proved to differ from the shellertype in sequent shelling and milling. The broken ratio, which occurred respectively in either shelling or milling, balanced rather on the shelling side. The entire broken ratio of sequent shelling and milling in the use of a Satake sheller was a little lower than that of Ohtake sheller . Regarding the dehusking efficiencies of three type shellers, average valuesin all the experiments for 28 varieties were within the range from 82.2 to 98%.These range were within the exceeding objective 80% in the laboratory and 98% in actual industrial mills. The lowest milling broken ratio was found in emery abrasive type whitener (Indosaw) among the polisher or whitener used, indicating their gentle milling action. However, this whitener exhibited non uniform whitening and resulted poor appearance of rough grain surface. A frictional type polisher (Yamamoto) exhibited the shinier appearance of polished grain surface, although, higher broken ratio after milling reduced the head rice yield substantially. Milled rice recovery obtained was around 70% as against 70 to 75% of most modem rice mill.

Title : Economics of Foundation Seed Production of Vegetable Crops at Agriculture Research Station Pahhribas Material Type: printed text Authors: P. K. Maharjan, Author ; T. R. Chapagain, Author ; P. L. Karna, Author ; D. Sah, Author Pagination: 288-290 p. Languages : English (eng) Keywords: economic viability, foundation seed, 1:1 ratio, supernormal profit Abstract: A study was carried out to access the economic viability of foundation seed production of
vegetable crops at agricultural research station. The study was conducted at Agricultural
Research Station, Pakhribas Dhankuta including four major vegetable crops namely: radish
(40 days and Mino Early), pea (Sikkim local and J/ 1050), broad leaf mustard (Tanklunm
local and Marpha broad leaf) and French bean (Four season and Trisuli). The result of the
study revealed that foundation seed can be produced in 1:1 ratio except in peas. It is
concluded that in the proper management condition with 1:1 BIC ratio foundation seed
production is possible.Link for e-copy: http://elibrary.narc.gov.np/?r=516 Economics of Foundation Seed Production of Vegetable Crops at Agriculture Research Station Pahhribas [printed text] / P. K.

Title : Pigeon Pea Based Intercropping System in Western Terai of Nepal Material Type: printed text Authors: Paudel C.L., Author Publication Date: 1997 Article on page: 1-5 p. Languages : English (eng) Keywords: Intercropping, pigeon pea cultivation, land equivalent ratio, sole crops Abstract: A field experiment of pigeon pea based intercropping system was conducted at the Regional Agriculture Research Station, Nepalgunj during 1991-92 and 1992-93 seasons with objectives to find out the effect of different inter-crop species on pigeon pea productivity and to develop profitable intercropping system for the rainfed upland areas of land. The experiment was conducted in Randomized Complete Block Design with sole pigeon pea and other crops and their combinations. The yield and yield components of pigeon pea were not affected by intercrops and the pigeon pea/maize intercropping in 1:1 ratio gave the highest monetary return and land equivalent ratio (LER) of 1.53. The yield advantage was more in intercropping than all sole systems, though the pigeon pea yield was reduced when it was intercropped with rice

Languages : English (eng) Keywords: Benefit cost ratio, growth substance, summer vegetable Abstract: Bottle gourd (Lagenaria siceraria) is one of the major summer vegetables in terai. Generally, it is noticed that when the day length increases, number of fruits decreases resulting to reduced yield. Therefore, this trial was conducted for two years (2004 and 2005) on Pusa Summer Prolific Long (PSPL) variety to identify proper growth substance for improving the yield of bottle gourd.
