Appropriate Cropping Pattern and Its Effect on Rhizome Rot Disease for Sustainable Ginger Production / G.K.C. ; Sharma, B.P.
Title : Appropriate Cropping Pattern and Its Effect on Rhizome Rot Disease for Sustainable Ginger Production Material Type: printed text Authors: G.K.C., Author ; Sharma, B.P., Author Pagination: 245-248 p. Languages : English (eng) Keywords: cropping pattern, disease severity, equivalent yield, ginger, rhizome rot Abstract: An experiment was carried out during 1997 to 2002 succeeding six ginger crop seasons at
Kapurkot, Salyan to assess the effect of continuous ginger cropping and different cropping
sequences on ginger yield and rhizome rot severity. Experiment was conducted under rainfed
south faced mid hill conditions ( 1500 m a s 1). Recommended package of practices for
individual crop production were followed. Among the different cropping sequences tested
maize- to ria :pole bean- tori a : ginger in first three years and repeated same sequence in the
second three years cycle was found to be mosi sustainable cropping pattern with highest
ginger rhizome yield at the end of second cycle (35.8 t/ha) followed by ginger yield at second
cycle (34.1 t/ha) when Soybean - wheat :finger millet : ginger , three years cropping
pattern adopted. Rhizomes yields obtained at 6'1
' years from above cropping pattern were
significantly higher than continuous sole ginger cropped up 'to the 6'11 year (9.8 tllza). These
two cropping sequences gave highest net return Rs. 114,400 and 100,800/ha respectively and
also were found effective in reducing rhizome rot disease severity (25.9 to 26.0%) compared
to continuous ginger cropping (50.9 %). The long-temr experiment results revealed that
growing either Pole· bean- tori a or finger millet prior to ginger crop in three-year ginger
based cropping sequei1ce was found appropriate for sustainable ginger production in
Kapurkot agro-climatic conditions.Link for e-copy: http://elibrary.narc.gov.np/?r=505 Appropriate Cropping Pattern and Its Effect on Rhizome Rot Disease for Sustainable Ginger Production [printed text] / G.K.C., Author ; Sharma, B.P., Author . - [s.d.] . - 245-248 p.

Title : Evaluation of rice genotypes against blast disease under field condition Material Type: printed text Authors: Nabin Kumar Dangal ; Bedanand Chaudhary, Author ; Parbati Joshi, Author ; Ang Tenjing Sherpa, Author Pagination: 323-330 p. Languages : English (eng) Keywords: Pyricularia grise a, genotype, disease severity, leaf blast and resist~ce Abstract: Blast of rice, caused by Pyricularia grisea, is one of the most important diseases of rice in
Nepal. It has been causing significant yield loss in all rice growing areas. A field screening
experiment was conducted to identify resistance in rice to the disease during 2011 and 2012
wet season at Regional Agricultural Research Station, Tarahara. A total of 134 (OBN -70,
RA VTRL-26, RA VTN-22 and Quality-16) rice genotypes were evaluated for resistance in
both the years. atural spread of the pathogen in the test lines was allowed from border lines I
inoculums rows planted around the nursery with mixture of susceptible varieties (i.e. Mansuli
and Sankharika). Conducive environment for blast development was created by planting four
rows of Sesbania eculeata around the experimental plot 35 days prior to seeding of test
genotypes. Scoring was done on 22 days after seeding and continued for three scorings at 7
days interval using 0-9 scale developed by IRRI. Area under disease progress curve (AUDPC)
varied significantly among the tested rice genotypes in both years. Disease severity varied 0 to
77.77%. Out of 134 entries, 58 entries were resistant to the disease during 2011 and 63 in
2012. Among them, IR09Fl12, IR09Fl20, IR09Fl27, IR09F158, IR09Fl66, IR09Fl74,

8-1-2-4(BR-32), Basundhara, Tarahara-1, Hardinath-2, Sura vi and Mahima were free from
blast in both the years. The number of moderately resistant (3 -4), moderately susceptible (5 -6)
and highly susceptible (7-9) genotypes was 43, 9 and 2 in 2011 and 54, 3 and 1 in 2012,
respectively. Disease severity increased in second and third scorings in all entries except the
resistant ones. IR09Fll0, NR 1887-8-1-1-2 and Kanchhi masuli were highly susceptible to
blast with the highest disease score (7) which were completely knocked down in the final
scoring.Link for e-copy: http://elibrary.narc.gov.np/?r=919 Evaluation of rice genotypes against blast disease under field condition [printed text] / Nabin Kumar Dangal ; Bedanand Chaudhary, Author ; Parbati Joshi, Author ; Ang Tenjing Sherpa, Author . - [s.d.] . - 323-330 p.
