Title : Assessment of maize stem borer, chilo partelius swinhoe infestation in year round weekly seeded maize varieties at NMRP, Rampur and its command areas Material Type: printed text Authors: Thakur, P., Editor ; G.S Bhandari ; BB Achami, Author Pagination: 288-294 p. Keywords: Maize genotypes ; maize stem borer infestation varieties temperature Abstract: Maize genotypes i.e. Arun 2 (Short duration), Rampur composite (Long duration) and
Gaurav (Hybrid) were seeded in weekly interval throughout the years at NMRP, Rampur
during two consecutive years, 201 0/ 11 and 2011112 to assess the effect of environment on
growth and development of Maize Stem Borer, Chilo partel/us Swinhoe infestation along
with other associated pests. Percent insects' damage was in the similar trend in both the
years proportional to prevailing temperature. Range of borer damage varied from 4.53% to
61.03 % in 20 I 0/1 1 and 4.4% to 64.9 % in 2011/12. The percent infestation of the years
was found highest in the month of April (58.2 %) followed by May (48.2 %), July (44.9 %)
and March (42.7 %) and approximately similar movement of damage were recorded in
other parameters (Score, Tunnel length and exit holes) too. Out of three varieties tested,
Gaurav was comparatively more sensitive to maize stem borer damage (37.7%) than Arun 2
(34.5%) and Rampur composite (32.1 %). Beside this, twenty two other miner insects and
six beneficial insects were also recorded but their damage was nominal. Furthermore,
insects survey carried out at NMRP command areas inferred that maize stem borer was
major one and more or less uniform in each location however average percent damage as
recorded in field was found more at Sukranagar, Chitwan (20.6%) than Manahari,
Makawanpur (14.6%) and Madi, Chitwan (11.3%).Link for e-copy: http://elibrary.narc.gov.np/?r=956 Assessment of maize stem borer, chilo partelius swinhoe infestation in year round weekly seeded maize varieties at NMRP, Rampur and its command areas [printed text] / Thakur, P., Editor ; G.S Bhandari ; BB Achami, Author . - [s.d.] . - 288-294 p.

[article]
Title : Effect of Plant Population on Bulb Size and Yield of Marketable Bulbs of Onion Varieties during Off Season Material Type: printed text Authors: S. Shakya, Author ; Shakya, S.M., Author ; S. K. Shah, Author ; A. Srivastava, Author Publication Date: 2015 Article on page: 85-94 p. Languages : English (eng) Keywords: Off season, onion, spacing, varieties Abstract: An experiment was conducted in Sunwal, Nawalparasi district of Nepal to assess the
effect of plant population on bulb size and marketable yield of two onion varieties
during rainy season of 2008. Two off season varieties of onion as main plot factor viz.
Agrifound Dark Red (AFDR) and N-53 and six different plant populations (125, 100,
83.34, 66.67, 50 and 33.34 plants per m2 ) obtained by using different spacings of 10×8,
10×10, 12×10,15×10, 20×10 and 20×15 cm as sub plot factors were used as
treatments and laid out in a split plot design with three replications. Marketable bulb
yield of AFDR (25.55 mt ha-1 ) was higher than that of N-53 (19.78 mt ha-1
). Marketable bulb yield was highest at closer spacing of 10×10 cm for both the varieties which was
26.97 mt ha-1 in AFDR and 22.48 mt ha-1 in N-53. The size of the bulbs increased with
increase in spacing. The most preferred size of bulb was found to be of diameter
between 3.5 to 5 cm whose yield was found highest (2.19 kg/plot) at the closest spacing
of 10×8 cm which was not statistically different from that (2.17 kg/plot) at the spacing
of 10×10 cm. The most preferred sized bulb yield showed a similar trend of increase
as total marketable bulb yield with decrease in spacing. The spacings of 12×10, 10×10
and 10×8 cm produced total marketable bulb yields which were not significantly
different from each other. The highest net return of Rs. 5,68,977 per hectare was found
at the spacing of 12×10 cm for the variety AFDR.

Title : Effect of Sowing Dates in Economic Return from Okra Varieties in Spring-Summer in Chitwan, Nepal Material Type: printed text Authors: Tika R. Chapagain, Author ; Shanta Man Shakya, Author ; Moha Dutta Sharma, Author ; Yubak Dhoj G.C., Author Pagination: 246-250 p. Languages : English (eng) Keywords: Net return, okra, spring season, sowing dates, varieties Abstract: An experiment was carried out at IAAS, horticulture farm to determine the effect of
sowing dates in economic return from okra varieties in spring sum'!ler in inner-terai
region of Ghitwan Nepal. Five. varieties of okra namely; Anokhi (Ft), Parvani Kranti, Arka
Anamika, Shagt.in and K-51 were planted at four different dates(~ March- 1ff' April) at
15 days interval with three replications in split plot design. A case study was also carried
out in Gunjanagar VDG of Ghitwan district to compare the cultivation costs of research
plot and on farm okra production. The highest net return (Rs 238,495.0/ha) .was obtained
from~ March sowing. However, the highest cultivation cost (Rs 98,920:0Jha) required
for the crop sown on 1 th March. The highest net return (Rs 273,387. 0/ha) was obtained
from Anokhi from ~ March sowing and the lowest net return was obtained from Parvani
Kmati (Rs 80,428.0) from 1st April sowing. The highest BIG ratio (2.81) was obtained
from Arka Anamika from ~ March sowing. During .case study, 4 different sowing times
were identified as major sowing times (1st week of February, 1st week of March, ~ week
of March & ~ week of July). The net return was higher (Rs 255, 400.0/ha) from 1st week
of February sowing. The highest BIG ratio (2.91)- was observed in the crop sown in 1st
week of March due to comparatively higher productivity and lower cultivation cost as
compared to 1st week of February.Link for e-copy: http://elibrary.narc.gov.np/?r=255 Effect of Sowing Dates in Economic Return from Okra Varieties in Spring-Summer in Chitwan, Nepal [printed text] / Tika R.
