Title : Effect of Organic Sources of Nutrients and Plant Protection on Productivity of Orthodox Tea (Camelia Sinensis Kuntz.) Material Type: printed text Authors: Subba, N., Author ; NP Adhikari, Author ; Ghimire, K., Author ; ASR Bajracharya, Author Pagination: 78-85 p. Languages : English (eng) Keywords: Gumli Selection, mineral oil, enanthole, azatobacter incorporated fertilizer Abstract: The growing demand of quality organic tea with increase in awareness on the deleterious effect of
chemicals and its residue in human health has revived the need of organic tea management. Field
experiments were conducted in 2006/2007 to 200712008 in flam and Dhankuta districts to study the
effect of di.fferent organic sources of nutrients and pest management on Orthodox tea cv. Gumti
Selection. In addition to productivity, the effect of nutrients on green leaf production trend,
plucking intervals in di.fferent months and changes in composition of soil in the experimental plots
were also studied Four di.fferent organic sources of nutrients; vermi compost, azatobacter
incorporated commercial organic fertilizer, improved ditch compost with EM. traditionally made
compost and di.fferent organic plant protection methods; enanthole, parasitic fungi Trichoderma
viride, mineral oil for management of blister blight disease and locally made botanical pesticide,
mineral oil and ultineem for management of thrips were tested separately in a Randomized
Complete Block Design (RCBD) with seven replications. The effect of different organic sources of
nutrients was found significant on green tea leaf production. In both districts, highest production of
green tea leaves was recorded in plots with azatobacter incorporated fertilizer and least informers'
traditional compost in both years. The result showed green leaf production of 3125 and 3031
kg/hac in 12-15 year old plantation and 1822 and 1798 kg/hac in 8-10 year old plantation with
yearly application of 495 gmlbush of azotobacter incorporated fertilizer. Di.fferent organic
treatments did not di.ffer significantly in the severity of blister blight disease. However, lowest
infestation was observed in plots with Trichoderma application. Leaf damage percentage was found
significantly lower in treatments other than control in both districts. The effect of organic thrips
management was significantly di.fferent in green tea leaf yield. Non significant changes in soil
chemical properties due to organic nutrients were found among the treatments. However, small
incremttnl in nitrogen and potassium contenl over the time was observed.Link for e-copy: http://elibrary.narc.gov.np/?r=1642 Effect of Organic Sources of Nutrients and Plant Protection on Productivity of Orthodox Tea (Camelia Sinensis Kuntz.)

Title : Evaluation of maize varieties against grey leaf (GLS) disease Material Type: printed text Authors: ASR Bajracharya, Editor ; D.L. Mandal, Author ; Chaudhary, R.N., Author Pagination: 322-325 p. Keywords: Cercospora zeae-maydis ; GLS Abstract: Maize grey leaf spot (GLS) caused by Cercospora zeae- maydis Tehon & Daniels causes
grain yield loss up to I 00 percent. Resistant varieties offer the best option for economic
control of the disease in Nepalese hill maize farming context. Considering the fact, released
maize varieties for mid and high hills along with some varieties from CIMMYT were
evaluated against the diseases at Pakhribas (1750 mas!) during 2009 and 2010 in RCB
design with two replications. The varieties included were Zm-627, Zm-525 and
Zm07SADVI (from CJMMYT) and Sheetal, Deuti, Ganesh-1, Mankamana-1,
Manakamana-3, Manakamana-4, Manakamna-6, Poshilo Makai-1 (released varieties) and
Farmers' local as check. Scoring was done three times on 1-5 scale given by Saghai and
Maroo (1993). The experiments conducted during 2009 and 2010 rainy season revealed that
genotypes Zm-627, Zm-525 and Zm07SADVJ were least affected by the diseases during
both the years. Recommended varieties Sheetala, Deuti and Ganesh-1 performed better than
local check in both years. Whereas, Mankamana-3, Mankamana-6, Poshilo Makai-1,
Mankamana-4 and Mankamana-1 were less affected by the disease as compared to local
check during 2010 but were more affected than local during 2009. On the basis of yield,
Ganesh-1 performed best during 2009 and Zm-07SADVI was best during 201 0.
Manakamana-1 and Manakamana-3 were worst yielder on GLS affected conditions whereas
other varieties were better than farmers' local. Per cent ear rot at the time of harvest was
minimum in farmers' local (2.38%) followed by Mankamana-3 (5.56%) and Ganesh-1
(5 .88%). Per cent ear rot in other varieties ranged between 11- 26%. Per cent ear rot at the
time of harvest fotmd to increase with increase in open cob percentage.Link for e-copy: http://elibrary.narc.gov.np/?r=962 Evaluation of maize varieties against grey leaf (GLS) disease [printed text] / ASR Bajracharya, Editor ; D.L. Mandal, Author ; Chaudhary, R.N., Author . - [s.d.] . - 322-325 p.
