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 : Long-term fertility trial for sustainable production of rice-wheat in mid and far western terai Material Type: printed text Authors: Srivastava S.P. ; G Baidhya, Author Pagination: 306-314 p. Languages : English (eng) Keywords: Nitrogen ; Phosphorus Potassium rice wheat Abstract: A long-term fertility trial at RARS Khajura indicates that nitrogen has been the key element
for the production of both rice and wheat in the system since the beginning of this experiment
in 1978179 till 2003104. This beccr"le possible because the soil of the experimental site had
contained higher available native phosphorus (155. 7 kg/ha) and higher available native
potassium (416.8 kglha) as benchmark. It is apparent from the years of study that the effect
ofnitroge!' is more pronounced on the production of rice than on wheat. The grain yield of
rice produced in response to 100 kg Nlha has remained quite comparable with 100: 30: 30
kg NPK/ha up to 26 years (2003104) and significantly higher than 10 ton compost /ha up to
10 years (1987188). However, form 1988189 the grain yield of rice has shown an increasing
trend in response to 1 0-ton compost/ha, which remained quite comparable with 100 kg Nlha
till 1995196 and then increased to a significant level from 1996/97 till 2003104. Also the
beneficial effect of compost is more pronounced on rice than on wheat because of rapid
mineralization during the rice-grol>l'ing season. For sustainable production of wheat nitrogen
alone is not enough. It must be combined with phosphorus tc sustain the yield. The
combination of nitrogen and phosphorus (100:30:0) is more important than that of nitrogen
and potassium (1 00:0: 30) for the grain yield production of wheat. This is because of higher
native potassium content than phosphorus in the soil. However, soil analysis indicates that
both phosphorus and potassium contents of the soil have been declining during the
succeeding years of experimentation. The low input treatments like 50:20:20, 50:0:0 and
50:20:0 have been producing lower yields of rice-wheat and therefore, do not appear to have
a sustainable effect.Link for e-copy: http://elibrary.narc.gov.np/?r=1116 Long-term fertility trial for sustainable production of rice-wheat in mid and far western terai [printed text] / Srivastava S.P. ; G Baidhya, Author . - [s.d.] . - 306-314 p.

Title : Long term fertility trial on maize toria rotation Material Type: printed text Authors: Srivastava S.P., Editor ; Neupane D.D., Author Pagination: 165-174 p. Abstract: Response of the ·first crop (maize) to the treatments
(manure, lime and fertilizers) under study was found
non-significant. However,- from the second crop (toria)
and third crop (maize) to eighth crop· (toria) and nineth
crop (maize) a significant response to the applied
manure, lime and fertilizers was detected. But in
comparision with the first year tQ.e grain yield of maize
increased in the second year with all the treatments
under study except the control and 10 ton compost/ha,
whereas in toria the grain yield decreased with all the
treatments under study. From third year both maize and
toria have been showing a gradual decline in grain
yields during the ::;ucceeding years till eighth crop

The response of maize in the first year to the treatments under study (manure, lime and fertilizers) was found to be non-significant. However, from the second year the grain yield of toria and from the third year the grain yield ofmaize were found to be consistently declining. From third year both maize and toria have beenshowing a gradual decline in grain yields during the succeeding years till 1998. The difference in response to calcite and dolomite lime was found non significant. Biotic and abiotcconstraints could be the reason for declining the yield of both crops. The sharp decline in thegrain yield suggests laboratory investigation and treatments modification.

Title : Present Status of Citrus Nursery Business in Dhankuta District Material Type: printed text Authors: B. Chalise, Author ; Paudyal, K.P., Author ; Srivastava S.P., Author ; K. Bhandari, Author Pagination: 1-8 p. Languages : English (eng) Keywords: Sapling, trifoliate orange, mother stock, shoot-tip grafting, nursery business. Abstract: Studies were conducted in Dhankuta district/a find the real situation of citrus nursery business in the
district during March-April, 2012. During the studies, jive n~~rseries were selected and similar sets of
questionnaires were prepared and given to fill to the nursery owners. Direct field observation,
measurement, personnel communication and secondary data were used during the study. From the
study it was revealed that 11 nurseries were producing saplings in Dlwnkuta, out of which six
nurseries were legally operated Most of them were producing grafted saplings while others producing
both grafted sapling and seedling. All the nurseries werefozmd to be located above 1000 meter above
mean sea level. The shoot-tip metl?od of grafting was found to be the most common method of grafting
onto trifoliate orange seedling rootstock at ve1y low height ranging from 6 em to 15 cm due to the poor
growth of the seedling. Most of the nurseries were maintaining the mother stock inside the screen
house but scions were taken from the open field mother plant. Major problems of(aising mother slock
inside I he screen house were high occurrence of citrus scales, aphids, white flies and sooty mould. The
age of sapling during selling time was found to be 6 month in most of the nurseries indicating high
demand of the sapling. Hardly, some saplings remained for the next year to sell. The income of the
citrus nurseries ranged from NRs. 300,000 to 660,575 per annum. Leaf miner, scale insect, lemon dog.
twig borers were the important insect pests while damping-off, powdery mildew, root rot, sooty mold
and twig blight were the major diseases of/he nurseries.Link for e-copy: http://elibrary.narc.gov.np/?r=421 Present Status of Citrus Nursery Business in Dhankuta District [printed text] / B.
