Bajracharya, Author ; Subba, N., Author ; J Mandal, Author ; Khatiwada, P.P., Author Pagination: 279-283 p. Languages : English (eng) Abstract: Gladiolus is very popular and commercial cut flower in Nepal. An experimental study was carried out at ARS, Pakhribas (1740 masl) with the objective to find out the appropriate planting depth and corm size to produce higher quality spike and higher corm yield. Three corm sizes 2.5-3 cm, 3-3.5 cm and 3.5-4 cm and three planting depths 6 cm, 8 cm and 10 cm were studied in factorial RCBD with three replications. The corm size did not show any significant effect on plant height…………..

Title : Effect of plant spacing on the yield and quality of flower, corm and cormel of gladiolus cv. jester Material Type: printed text Authors: S. Piya, Author ; Ajaya S. R. Bajracharya, Author ; Jawahar L.Mandal, Author Pagination: 183-187 p. Languages : English (eng) Abstract: Gladiolus is the most important cut flower among the bulbous flower, being commercially grown in Nepal. Plant spacing is one of the most important agronomic factors that affect the vegetative growth, yield and quality of flower, corm and cormels. In order to find the optimum plant spacing of gladiolus cv. Jester for mid hills of Nepal, experiments were conducted for two consecutive years 2006 and 2007 at Agriculture Research Station, Pakhribas. There were eight plant spacing as treatment, 20x15, 20x20, 20x25, 20x30, 30x15, 30x20, 30x25 and 30x30 cm with three replications. The experiment was laid out in randomized complete block design. The results showed that earliest spike harvesting days (75.37 d in 2006 and 90.07 d in 2007) in spacing 30x30 cm. First pair of flower opening after spike emergence was found earliest (14.83) from 30x25 cm in 2006 while in 14.57 days in 2007 from 30x30 cm. Largest flower size (10.902 cm) was recorded from 30x30 cm spacing in 2006 and 10.083 cm from 20x30 cm in 2007. In 2006, greater number of florets per spike (18.83) was recorded from 20x30 cm and in 2007 it was insignificant. Similarly, longest spike (104.60 cm and 101.90 cm) was found from 30x30 cm spacing in both 2006 and 2007, respectively. In case of average weight of daughter corm 20x30 cm produced maximum in 2006 while in 2007 it was found from 30x30 cm. Same result obtained for corm size, 20x30 cm gave largest corm in 2006 and by 30x30 in 2007. Finally, higher daughter corm yield (29746 kg/ha in 2006 and 17179 kg/ha in 2007) were acquired from narrower spacing (20x15 cm). Considering all of these results, it can be concluded that spacing 30x30 cm and 20x30 cm are best for both flower quality and corm size of gladiolus cv. Jester for mid hills of Nepal.

Title : Evaluation of Insecticides Against Plutella Xylostella L., Pieris Brassicae L. and Brevicoryne Brassicae L. on March-May Cauliflower in Ars, Pakhribas. Material Type: printed text Authors: Ajaya S. R. Bajracharya, Author ; Sharmila Piya, Author ; RN Chaudhary, Author ; Dhanik L. Mandal, Author Pagination: 31-34 p. Languages : English (eng) Keywords: DBM, Cabbage butterfly, aphid Abstract: Effectiveness of four botanicals and four chemical insecticides for the control of Diamond back moth
(Plutella xylostella L.), Cabbage butterfly (Pieris brassicae L.) and Cabbage aphid (Brevicoryne
brassicae) on March-May cauliflower w~s evaluated at ARS, Pakhribas (1750 masl) during 2011 and
2012. Plants of" Snow Crown" variety of cauliflower were sprayed twice fortnightly after 20 days of
planting in the main field with Commercial azadirachtin formulation (0.003 %), Aqueous Melia
azedarach leaf extract, Aqueous tobacco extract + soap, Aqueous solution of Acorus calamus rhizome
powder, Cypermethrin 0.025%, Malathion 0.05%, Endosulfan 0.15% and Dichlorvos 0.075%. Each
treatment was replicated four times along with control. Pest. scoring was done twice after spraying.
Endosulfan 0.15%, Malathion 0.05% and Aqueous tobacco extract + soap were found superior among
all the insecticides to control the Diamond back moth. All four chemical insecticides including
Commercial azadirachtin formulation (0.003 %) and Aqueous tobacco extract + soap were equally
effective in controlling Cabbage butterfly. Aqueous Melia azedarach leaf extract was found ineffective
to control both Diamond back moth and Cabbage butterfly during both years. All the botanicals as well
as chemical insecticides were significantly effective in reducing Cabbage aphid population; however,
Endosulfan 0.15% and Aqueous tobacco extract+ soap were superior. Endosulfan treated plots yielded
the highest biomass of more than 22.25 kg in both the years.Link for e-copy: http://elibrary.narc.gov.np/?r=1558 Evaluation of Insecticides Against Plutella Xylostella L., Pieris Brassicae L. and Brevicoryne Brassicae L. on March-May Cauliflower in Ars, Pakhribas.

Title : Study on Efficacy of v Arlo Us Insecticides and Botanicals Against Insect Pests (Plutel/A Xylostel/A L., Pieris B!'Assicae L. and Brevicoryne Brassicae L.) of Off-Season Cabbage Production in the Eastern Hills of Nepal Material Type: printed text Authors: Ajaya S. R. Bajracharya, Author ; Sharmila Piya, Author ; Keshab Ghimire, Author ; Dhanik L. Mandal, Author ; Shiva N. Mehta, Author Pagination: 131-135 p. Languages : English (eng) Keywords: DBM. Cabbage butterfly, aphid Abstract: Farmers of the eastern hills grow cabbage during off-season (April-October) period to the plains
for higher market prices but production during this period is risky with the potential losses to
insect pests: cabbage butterfly (Pieris brassicae L.), diamond back moths (Piutella xylostella L.)
and aphid (Brevicoryne brassicae L.). Considering this fact, an experiment in RCBD with three
replications was conducted to identify suitable chemical and botanical insecticides against cabbage
pests: diamond back moth (Piutella xylostella L.). cabbage butterfly (Pieris brassicae L.) and aphid
(Brevicoryne brassicae L.) at ARS, Pakhribas (1750 mas/) during 2008 and 2009 March-May
production with variety, "Green Coronet". Treatments included were Commercial azadirachtin
formulation (0.003 ·%}, Aqueous Melia azedarach leaf extract, Aqueous tobacco extract + soap,
Aqueous solution Acorus calamus rhizome powder/Deltamethrin 0.003%, Cypermethrin 0.025%,
Malathion 0.05%, Endosulfan 0.15%, Dichlorvos 0.075%, combination of botanicals and control.
The result showed that diamond back moth had developed resistance to Cypermethrin 0.025% due
to its use since a long time in vegetable cultivation. Melia azedarach leaf extract and Acarus
calamus rhizome extract are ineffective in controlling insect pests of cabbage. Application of either
of commercial azadirachtinformu/ation (0.003 %), Aqueous tobacco extract+ soap, Deltamethrin
0.003%, Malathion 0.05%, Endosulfan 0./5% and Dichlorvos 0.075% twice fortnightly: two
weeks after transplanting cabbage seedling provide sufficient protection from diamond back moth,
cabbage butterfly and aphid Alternate use of botanicals (Azadirachtin and tobacco) with chemical
pesticides (Deltamethrin, Endosulfan, Malathion and Dichlorovos) could be a better option to
reduce selection pressure on DBM larvae.Link for e-copy: http://elibrary.narc.gov.np/?r=1654 Study on Efficacy of v Arlo Us Insecticides and Botanicals Against Insect Pests (Plutel/A Xylostel/A L., Pieris B!'Assicae L. and Brevicoryne Brassicae L.) of Off-Season Cabbage Production in the Eastern Hills of Nepal [printed text] / Ajaya S.
