Title : Effect of Different Rhizome Covers on Productivity of Large Cardamom (Amomum subulatum Rox.) Material Type: printed text Authors: Neelam Subba, Author ; Purushottam P. Khatiwada, Author ; Keshab Ghimire, Author ; Ajaya S. Ratna Bajracharya, Author ; Shree P. Bista, Author ; Banhu P. Choudhary, Author Pagination: 212-215 p. Languages : English (eng) Keywords: Amomum subulatum, old plantation, rhizome covers, yield Abstract: Field e;cperiments were conducted for three consecutive years (2005 -2007) in /lam to
study the effect of different rhizome covers in more than 25 year old large cardamom
plantation. Four different rhizome covers; old pseudo stems, shrubs and twigs, mixture
of old pseudo stems with shrubs and bamboo mat support on lower side of clumps
were tested against traditional practice of leaving old bush as such. These rhizome
covers were tested in a Randomized Complete Block Design (RCBD) with four
replications. Unit plot size was 9 Sq m with a total experimental area of 180 Sq m. The
effect of different rhizome covers was found significant on yield and yield attributing
characters. Highest number of new pseudo stems (26.9 and 32.2) was recorded in
shrubs and twigs and lowest (10.1 and 14.5) in traditional practice in two years
respectively. Highest number of bracts (480) and capsules (647) were recorded in plots
with bamboo mat. This rhizome cover treatment might provide large cardamom
growers reluctant . to remove old bushes with an alternate method of increasing
productivity of old plantation.Link for e-copy: http://elibrary.narc.gov.np/?r=248 Effect of Different Rhizome Covers on Productivity of Large Cardamom (Amomum subulatum Rox.)

Title : Identification of Factors Causing Poor and Irregular Germination in Large Cardamom Seed (Amomum subulatum Rox.) Material Type: printed text Authors: Neelam Subba, Author ; Keshab Ghimire, Author ; Purushottam P. Khatiwada, Author ; Jyala Bajracharya, Author ; Sharmila Piya, Author Pagination: 220-226 p. Languages : English (eng) Keywords: Amomum subulatum, poor and irregular germination, embryo immaturity,
oxygen impermeabilityAbstract: Large cardamom seed remain dormant for six to eight months in field conditions. In
addition, poor and irregular germination is the major problem in nursery raising of large
cardamom. Different factors causing dormancy were studied in 2062/63-2063/64 at
Agricultural Research Station, Pakhribas and Seed Technology Research Division,
Khumaltar. Large Cardamom cv. Ramsahi was subjected to following hypothesis;
dormancy due to poor water permeability, poor oxygen exchange, presen_s;e- of water
soluble inhibitors, embryo immaturity or a combination of more than one factors. Hard
seed coat did not impose significant barriers to moisture uptake in large cardamom
seed. Different dormancy relieving treatments to test the above hypothesis differed
significantly in number of germinated seed placed in alternating temperature regime of
30°C and 200C for 8 and 16/:Jrs respectively. Earliest germination within 30 days was
I
observed in seed treated for embryo maturation and oxygen permeability and highest
percent germination (66%} was observed in the first four months in seed treated for
oxygen permeability. Seed treated for oxygen permeability after 3 minutes scarification
with uniform sized gravels when sown in nursery showed > 40% germination in field in
the first four months. It can be concluded that not one but the combination of above
mentioned factors are responsible for causing dormancy in large cardamom.Identification of Factors Causing Poor and Irregular Germination in Large Cardamom Seed (Amomum subulatum Rox.)

acclimatized in polyetha.ne bags inside plastic tunnel for four weeks followed by
transf()rring them into the glasshouse. The results reveled that an efficient system for in
