Title : Ecology and Management of Terrestrial Snails in Western Region of Nepal Material Type: printed text Authors: Him P. Pathak, Author ; Yuba R. Bhusal, Author ; Ram B. KC, Author Pagination: 116-121 p. Languages : English (eng) Keywords: Copper sulphate, damage, ecology, host crops, mortality, snails Abstract: Survey and field experiments were conducted at ARS, Pokhara, during 2003 and 2004
to know the ecology and effectiveness of different materials against terrestrial snails.
Field experiment was laid out in randomized complete block design with seven
treatments and four replications. Each treatment plot consisted of one clump of banana
with 3 stems having 15 leaves and 50 snails (Cryptaustenia sp.). All treatments were
applied in July. Survey conducted in Kaski, Tanahun, Syangja, Parvat, Nawalparasi
and Rupandehi revealed that five species of snails, namely Lissachatina fulica,
Cryptaustenia sp., Macrochlamys sp, Euaustenia sp.and Bensonia sp. were recorded
as crop pests. They were found to feed most preferably on chayote followed by tane
bodi, maize and sponge gourd in the field whereas in host choice condition, tane bodi,
french bean, maize, chayote, sponge gourd and yam were in sequence of preference
rank and the least preferred were ginger, turmeric and egg plant. The snails in field
were seen just after 2-3 showers of rain during April-May, maximum peak in July, and
theirr activity stopped with the end of monsoon. Two years mean data on snail mortality
due to treatments revealed that the spray of copper sulphate @ 5g//iter of water gave
significantly maximum mortality of snails (86.20 %). Common salt + agriculture
lime (1:5) @ 10 g/liter of water(78.90%) and dust of common salt+ wood ash (1: 5)
@ 30 kg/ha (74.60 %) were at par to cause snail mortality within 7 days after
application compared to that of untreated control (8.52 %).Link for e-copy: http://elibrary.narc.gov.np/?r=230 Ecology and Management of Terrestrial Snails in Western Region of Nepal [printed text] / Him P. Pathak, Author ; Yuba R. Bhusal, Author ; Ram B. KC, Author . - [s.d.] . - 116-121 p.

Title : Evaluation of Different Varieties of Banana at Agriculture Research Station (Horticulture), Malepatan, Pokhara Material Type: printed text Authors: Yubraj Bhusal, Author ; Madhu S. Ghale, Author ; Him P. Pathak, Author Pagination: 75-78 p. Languages : English (eng) Abstract: An experiment was conducted to evaluate different varieties of banana at Pokhara
condition in 061/62. Eight varieties of banana namely William hybrid, FIA 1, FIA 23,
Robusta, Harichhal, Chinia Champa, Dhurse and Local Malbhog were studied in
Randomized Complete Block design (RCBD) with four replications. The study showed
higher number of combs per plant in William hybrid (10.25), Robusta (10.25), Chinia
Champa (11) and Malbhog (10.5) which are statistically at par but FIA 1, FIA 23,
Dhurse and Harichhal bore less number of combs per plant. Higher finger number (18)
per comb was observed in William hybrid and least in Dhurse (10.5/comb). Although
the length and diameter of finger was found highest in Dhurse, the total yield was less
because of fewer numbers of fingers per plant. Average fruit weight was highest
(169.90 gm) in Dhurse while William hybrid, FIA 1 and Harichhal produced smaller
fruits (112.70 gm, 108.80 gm, and 102.60 gm respectively). Fruit taste was good in
William hybrid, Robusta, and Malbhog where as it was acidic in FIA 1 and Dhurse. The
result on evaluation of varieties for winter damage showed that the most susceptible
variety was Harichhal followed by Malbhog, Dhurse, Robusta, Chinia Champa, William
hybrid, and least affected varieties were FIA 1, FIA 23.Link for e-copy: http://elibrary.narc.gov.np/?r=209 Evaluation of Different Varieties of Banana at Agriculture Research Station (Horticulture), Malepatan, Pokhara [printed text] / Yubraj Bhusal, Author ; Madhu S.
