Title : Cost and Break Even Analysis of Milk Production in Lalitpur District Material Type: printed text Authors: R. P. Bhari, Author ; R.P. Yadav, Author Pagination: 227-244 p. Languages : English (eng) Abstract: The present study was conducted on 79 milk producing farmers of ht'O village development
committees (VDCs) (Chapagaun and Lele) of Lalitpur district using survey method during the
fiscal year 1997198. The results revealed that the total maintenance cost per milch animal per
day in cross-bred/improved cow and buffalo was higher (Rs. 77.79 and Rs. 87.60) than local
(Rs. 37.52 and Rs. 52.84) respectively and this increased with increase infann size. Feed was
the most important cost item accounting for about 40 per cent of the total maintenance cost
followed by labour (about 39 per cent) in both cows and buffaloes and in almost all sizegroup
of farms. The gross income per milch animal per day in cow and buffalo for crossbred/
improved breed~ was observed higher (Rs. 72.50 and Rs. 82.81 respectively) than in
local (Rs. 33.29 and Rs. 43.94) and was directly proportional to the farm size. The cost of
milk production per litre was computed as Rs. 18. 7 4 and Rs. 19. 69 in cow and Rs. 18.46 and
Rs. 21.01 in buffalo, in cross-bred/improved and local breed respectively. The net loss over;
cost C (total cost) was found Rs. 5.29 and Rs. 4.23 in cow and Rs. 4. 79 and Rs. 8.90 in
b71ffalo per day per milch animal in cross-bred/improved and local breed respectively.
However, the net profit per milch animal per day over cost B (excluding family labour from
the total cost) in cow and buffalo was found positive and higher in cross-bred/improved (Rs.
26.25 and Rs. 29.60 respectively) than in local (Rs. 9.85 and Rs. 8. 75). The breakeven
analy~is indicated that the breakeven milk production per milch animal per day in crossbred/
unproved cow and buffalo was lower (6.32 and 6.06 litre) than that of local (6.92 and
7.91/itre).Link for e-copy: http://elibrary.narc.gov.np/?r=414 Cost and Break Even Analysis of Milk Production in Lalitpur District [printed text] / R. P. Bhari, Author ; R.P. Yadav, Author . - [s.d.] . - 227-244 p.

Title : Eco-friendly Management of Aphids in Cucumber through Integrated Approaches in Western Hills of Nepal Material Type: printed text Authors: R.C .Gouli, Author ; Gautam, I.P., Author ; R.P. Yadav, Author Pagination: 240-245 p. Languages : English (eng) Keywords: Aphid monitoring, biological control, Chrysoperla carnea, cucumber
mosaic virusAbstract: Experiments were c_onducted.in /PM laboratory and Research Command Areas (RCA)
of Regional Agricultural Research Station (RARS), Lumle from 2004-2006 to generate
eco-friendly aphid management practices in cucumber production. Study on the year
round population dynamics of aphids in different agro-ecological zones, mass
multiplication of their biological control agent and their augmentative release against
aphids in controlled field condition were carried out as an important component of
biological pest management approach. The results revealed that the year round
population dynamics of cucumber mosaic virus (cmv) vectors (aphids) were traced out
at different agro-ecological research/outreach sites and peak pest activity period was
found to be November to March thereafter it started declining. It was possible to
multiply aphid biological control agent Chrysoperla carnea at controlled laboratory
condition in different artificial diet combinations. The effectiveness of laboratory
produced C. carnea against aphid was also assessed in controlled field condition and
the result showed that augmented release of this predator was found effective in
managing the population of aphids t~ansmitting cucumber mosaic virus, decreased the
intensity of virus infestation thereby 27.20% higher fruit yield was obtained as
compared to the controlled plot. Any symptoms of CMV disease were not observed in
Chrysoperla released plot, whereas in control plot, 7.5% plants showed CMV
symptoms.Link for e-copy: http://elibrary.narc.gov.np/?r=254 Eco-friendly Management of Aphids in Cucumber through Integrated Approaches in Western Hills of Nepal [printed text] / R.C .Gouli, Author ; Gautam, I.P., Author ; R.P. Yadav, Author . - [s.d.] . - 240-245 p.

Title : Influence of age of seedling on productivity of rice under rain fed lowland condition Material Type: printed text Authors: Bhurer, K.P. ; Adhikari, N.P., Author ; R.P. Yadav, Author Pagination: 80-81 p. Languages : English (eng) Abstract: Field experiments ·were conducted during the normal season of 1994 and 1995 at the
National Rice Research Program, Parwanipur under rainfed lowland condition. The
objective of the experiment was to find out the effect of age of seedling on grain yield of
thr:ee rice genotypes namely Radha-11 , RP 101 7, and RD-21. Seedling age up to 55 days did
not reduce the grain yield of tested rice genotypes. Days to maturity increased with the
increase in age of seedlings. Results of this study indicates that farmers can use older
seedlings of these genotypes without losing grain yield. However, younger seedlings rna~ be
preferred for transplanting to suit in to rice-wheat cropping pattern.Link for e-copy: http://elibrary.narc.gov.np/?r=436 Influence of age of seedling on productivity of rice under rain fed lowland condition [printed text] / Bhurer, K.P. ; Adhikari, N.P., Author ; R.P.
