Title : Evaluation of cauliflower varieties and their planting dates for commercial production under Jumla Agro-Ecological Condition Material Type: printed text Authors: Pandey, Y.R., Author Pagination: 207-210 p. Languages : English (eng) Keywords: Cauliflower, Jumla agro-ecology, planting dates Abstract: Field experiments were conducted at Agriculture Research Station, Rajikot, Jumla (2330 mast) in two consecutive years 1999/2000 and 2000/2001 to identify cauliflower varieties suitable under Jumla agro ecological condition and their appropriate planting dates for extended production period. Five varieties of cauliflower, namely Jyapu Local, Snow Crown, Snowball-16, Kibo Giant and Kathamandu Local were included in the experiment. These varieties were seeded in the nursery in three different dates at one-month interval on 23rd of March, April, and May………

Title : Mapping Phalaris minor under the Rice-Wheat Cropping System in Different Agro-Ecological Regions of Nepal Material Type: printed text Authors: Ranjit, Jagat Devi, Author ; ,Bellinder, Robin, Author ; Hobbs, Peter R., Author Publication Date: 2006 Article on page: 54-63 p Languages : English (eng) Keywords: Agro-ecology, Phalaris minor, survey, weeds, wheat Abstract: A survey was conducted in order to map the spread of Phalaris minor in wheat in nine districts
in the mid-hill, Terai and inner Terai areas of the rice-wheat cropping system in Nepal during
1998/99. Both qualitative and quantitative data were collected from 540 farmers and P. minor
was recorded in all of the nine surveyed districts. Percent summed dominance ratio (SDR) and
average number per unit area (m2) of P. minor was compared to different districts of mid-hills,
inner Tarai, and Tarai belts along with other weeds in the wheat crop. P. minor ranked as the
first and second important weed of wheat that reduced the wheat yield from 10 to 50 percent. Its
populations varied from district to district. However, the infestation appeared to be in increasing
trend. Future strategies need to consider in increasing growers’ abilities to identify P. minor at
early growth stages when it is particularly difficult to differentiate from wheat seedlings. It is
suggested that frequent monitoring of weeds in different tillage and weed management practices
should be initiated. Besides farmers’ training in the future there needs to be emphasis placed on
increasing farmer’s awareness on the serious negative impact of P. minor on wheat yield and
quality.Link for e-copy: http://elibrary.narc.gov.np/?r=47

Title : Population Dynamics of Helicov_Erpa Armigera Hubner and Spodoptera Litura Fabricws: (Lepidoptera: Noctuidae) in Different Agroecological Condition of Nepal Material Type: printed text Authors: N. Dangi, Author ; S. Aryal, Author ; Shrestha, S., Author ; Giri, Y.P., Author ; M. Sporleder, Author Pagination: 79-82 p. Languages : English (eng) Keywords: Agro-ecology, Potato, Lepidoptera, Pheromones, Trap Abstract: The flight activity of two lepidopteron insect pests, Spodoptera litura and Helicoverpa armigera,
(Lepidoptera: Noctuidae) was monitored using sex pheromone traps during two consecutive vegetation
periods in 3 different potato field locations situated at altitudes of around 2500, 1500 and 650 mas/ in
Sindupalchowk, Kavrepa1anchowk and Dang district, respectively. Pheromone traps were installed at
three locations in each site and data were recorded at 2 days interval. Populations of the two pests
were observed the highest in Kavrepalanchowk during both vegetation period 2010111 and 2011112.
Data were pooled weekly and pheromone traps detected distinct peaks for S. litura in Sindupalchowk
on 10'h April (1034±219), Kavrepalanchowk on 6'h April (2932±224) and Dang on 20'1' November
(527±32) in 20101011. Likewise, in Kavrepalanchowk and Dang, the highest peak was observed on
22nd March (950±733) and IO'h November (747±468) during 20111012. respectively. Population of H.
armigera at Kavrepalanchowk peaked on 23nl March with an economically significant number
(373±38 per week in Tukucha VDC and 1207±359 per week in Panauti VDC) where as visible damage
was observed on potato foliage in 2011. In Dang, H. armigera moth captured reached its peak on 30'h
November (32±32 adult/week). This trend clearly indicated that these pests can outbreak at tuber
bulking and maturation stage of potato in all three ecological regions of Nepal. Therefore, these pests
cause severe economic damage during the vegetation period of the potato crop. These dates on which
the highest number of moths were trapped could be used as a benchmark to determine the occurrence
and population buikfup duration for these two species of moths. Understanding the pest population
dynamics are useful technical knowledge needed for researchers, technicians and· growers to decide
more precise timing for applying appropriate management options.Link for e-copy: http://elibrary.narc.gov.np/?r=1583 Population Dynamics of Helicov_Erpa Armigera Hubner and Spodoptera Litura Fabricws: (Lepidoptera: Noctuidae) in Different Agroecological Condition of Nepal [printed text] / N.
