Title : Effect of Grafting Height on Success and Growth of Acid Lime (Citrus Alll:Antifolia Swingle) Sapling Material Type: printed text Authors: B. Chalise, Author ; Paudyal, K.P., Author ; Srivastava S.P., Author ; Thakur, M.K., Author ; ,Subedi, H.P., Author ; K. Bhandari, Author Pagination: 1-8 p. Languages : English (eng) Keywords: Citrus aurantifolia, Poncirus trifoliata, shoot-tip, callus, graft success, spread and
canopy volumeAbstract: A field experiment was conducted at National Citrus Research Program (NCRP), Paripatle,
Dhankuta to determine the best grafting height for the highest success of grafting and the maximum
growth of sapling during r' January to 30'h December, 2010. Scions were collected from the
mother plant 'NCRP-49' grown under screen house and grafted on to one-year-old trifoliate orange
seedling rootstocks by shoot-tip method at 4 em, 8 em, 12 em, 16 em and 20 em height from the
collar region as the treatment. The grafts were planted inside the closed tunnel made from bamboo
splits, jute and plastic sheet at JOx8 em spacing in 64x/OO em experimental plots laid out in
randomized complete block design (RCBD) with four replications containing 80 grafts per plot.
Treatments were allotted on the experimental plots randomly. The success of grafting was not
affected by the height of grafting, however growth of sapling was found significantly affected by the
height of grafting. Observation taken on sapling after one year of grafting revealed that the
maximum scion height (42.13 em), the highest number of/eaves per sapling (47.50), the highest
growth of scion diameter (55.61%), maximum length of primary branches (31.19 em), maximum
number of secondary branches per sapling ((3.24), the highest length of secondary branches (11.59
em), the highest canopy volume (15440 cm3
) and the highest graft spread (24.35 em) were found on
sapling grafted at 16 em height of the trifoliate orange rootstock. Hence, from the study it is
concluded that the most suitable height of grafting acid lime on trifoliate orange rootstock was 16

Title : Screen House System to Produce Quality Planting Materials of Citrus in Banepa Material Type: printed text Authors: C. Regmi, Author ; I.P. Kafle, Author ; Paudyal, K.P., Author ; R.P. Devkota, Author ; G. Aryal, Author ; G. Awasthi, Author Pagination: 89-92 p. Languages : English (eng) Keywords: Citrus saplings,' graft transmissible diseaes, nursery, screen. house, vectors Abstract: Citrus is the dominant fruit crop in mid-hills of Nepal. The productivity is very low
(about 10 mt/ha) as compared to 20-25 mtlha world average. It is mainly due to the
traditional methods of cultivation, use of seedlings as planting materials, wide
spread of graft transmi~sible diseases such as Huanglongbing and other viral
diseases and infestation of most devastating fungal. diseases like Phytophthora.
Production of grafted saplings of good quality and supply to the farmers are the
prerequisites to increase the productivity of citrus. The project was started in 2005
with the construction of well managed two screen houses (20x9x3 .m3 in size) in
Banepa for production and distribution of disease free planting materials in Nepal.
The project applied the achievements made by the other institutions. Mandarins
access no. J-90 selected based on the 5 y~ars evaluation by National Citrus
Research program and confirmed HLB free in PCR test by NAST, has been used
for mother plant. The screen with 10 mess was usee! in the screen .house which did
not allow entrance of any insects including aphids and -psyllids .a,n.d avoid- the
chances of infection of nursery plants by any type of vector transmissible disea~es.
Seventy mother plants are being maintained in thE! screen house. The screen
houses had the capacity of producing 10 thousand grafted citrus saplings annually.
Good quality citrus saplings were produced within a year due to enhanced growth
of plants inside screen house. This is one of the .best moctels for producing quality.
