Agronomic Performances of Rice and Potato in Different Cropping Patterns / Ram B. Khatri Chhetri in Nepal Agriculture Research Journal, Vol. 5 (2004)
Title : Agronomic Performances of Rice and Potato in Different Cropping Patterns Material Type: printed text Authors: Ram B. Khatri Chhetri, Author ; Khatri, B.B., Author ; R. Mishra, Author ; Joshi, Bal K., Author Publication Date: 2004 Article on page: 1-4 p Languages : English (eng) Keywords: Biomass, cropping patterns, sequence, legumes, tuber yield, grain yield Abstract: Cropping sequence affects grain crop yields. Nine different cropping patterns (CPs) were analyzed
to know the effect of cropping sequences on rice grain and potato tuber yields, to study the role
of legumes as green manure crop and to relate the biomass incorporated in soil with rice and tuber
yields. Four cropping patterns such as vetch-fallow-rice, rice-bean-fallow-rice, berseem-fallow-
rice and dhaincha-rice-potato gave higher rice yields than the CPs with chemical fertilizers. In
tuber yield, dhaincha-rice-potato sequence gave the highest response among the CPs with no
fertilizers. There were increment in both rice grain and potato tuber yields as biomass
incorporated in soil was increased. Rotation on crops with legumes at least once in a year can be
considered as important factor in sustaining production system.Link for e-copy: http://elibrary.narc.gov.np/?r=71

Title : Genetic Diversity in Nepalese Wheat Cultivars Based on Agro-Morphological Traits and Coefficients of Parentage Material Type: printed text Authors: Joshi, Bal K., Author ; Ashok Mudwari, Author ; Bhatta, M.R., Author Publication Date: 2004 Article on page: 7-17 p Languages : English (eng) Keywords: Agromorphological traits, coefficient of parentage, genetic diversity, Nepalese wheat cultivars Abstract: Genetic diversity between parents is necessary to derive transgenic segregants from a cross.
Coefficient of parentage (COP) and agromorphological traits (AMT) can be used to estimate
diversity among cultivars. The pedigrees of 26 bread wheat cultivars were traced back to 77
ancestors and computed coefficient of parentage for all pair-wise combinations. All the cultivars
used in the pedigree analysis were evaluated for six agromorphological traits in the National
Wheat Research Programme (NWRP), Bhairahawa, Nepal in 1996. Six quantitative variables were
used to compute dissimilarity distance matrix. Cluster and principal components analyses were
performed on the matrix of COP and AMT values. COP matrix and the matrix based on
agromorphological traits were compared. Mexico, India and Nepal were countries of the origin for
26 cultivars. A total of 77 ancestors originated from 22 different countries were used to develop
these cultivars. Most of the ancestors were aestivum (80.52%) and spring growth habit (64.94%).
Maximum dissimilarity was between RR 21 and Annapurna 3 and the most closely related pair
was Rohini and BL 1022 based on the AMT. The mean of COP for all cultivars was 0.159
0.256. The highest COP was between Annapurna 3 and Annapurna 2. Other more closely related
pairs based on COP were Kalyansona and Annapurna 2, Pasang Lhamu and Annapurna 3, UP 262
and RR 21, Vaskar and Kalyansona, NL 297 and BL 1473, Pasang Lhamu and Annapurna 1.
Completely unrelated pairs were L 52 and HD 1982, L 52 and Kalyansona, LR 64 and
Kalyansona, Kalyansona and HD 1982, PI and Kalyansona, PI and L 52, RR 21 and HD 1982, RR
21 and Kalyansona, RR 21 and PI. Fifteen ancestors were present in at least about 65% of the
cultivars. 17 ancestors had been used more frequently. Five and six clusters were formed based on
AMT and COP, respectively. Correlation coefficient between COP and AMT was 0.18 (P =
0.0168). Cultivars surveyed represent a wide range of variation for different areas of origin and
adaptation. This genetic variation may be useful for further improvement of wheat and it is
necessary to conserve them.Link for e-copy: http://elibrary.narc.gov.np/?r=72

Title : Some Local Potato Cultivars and their Reaction to Viruses Material Type: printed text Authors: Khatri, B.B., Author ; Surendra L. Shrestha, Author Publication Date: 2004 Article on page: 19-21 p Languages : English (eng) Keywords: Local cultivars, potato, tuber yield, virus diseases Abstract: ABSTRACT
Potato Research Programme (PRP) started initial studies of local potato cultivars since 1988/89 in
Nepal, to understand the plant and yield characteristics of these cultivars and to explore potato
cultivars diversity in the country. More activities on germplasm collection, characterization and
performance evaluation were carried out at Khumaltar. Twenty-one local cultivars collected from
different parts of the country were evaluated and compared with check varieties. The studies were
carried out in the laboratory of PRP, Khumaltar for identification and rating of these cultivars
for virus diseases. The presence of different viruses was observed in almost all cultivars tested.
However, the degree of infection was different. The tuber yields of almost all tested stocks were
found infected by virus diseases and as a result, a large number of small sized tubers per plant
were produced. However, combined results of tuber characteristics showed that cultivars Farse
White, Rosita, Khumbule and Lumle Red were superior to Kufri Jyoti in tuber yields over the years.Link for e-copy: http://elibrary.narc.gov.np/?r=73

Title : Use of Chemical Fertilizers on Potatoes in Sandy Loam Soil under Humid Sub-Tropical Condition of Chitwan Material Type: printed text Authors: Adhikari, R.C., Author ; Sharma, Mohadatta, Author Publication Date: 2004 Article on page: 23-26 p Languages : English (eng) Keywords: Desiree, Kufri Sinduri, nutrients, potato, tuber yield Abstract: An experiment was conducted at Rampur, Chitwan to study the effects of N, P2O5 and K2O on
tuber yield, quality and leaf nutrient status of potato cv. Kufri Sinduri and Desiree. The highest
potato tuber yields (35.7 and 21.1 t ha -1) were obtained with 150:100:100 and 100:100:100 of
N:P2O5:K2O kg ha-1 respectively of Kufri Sinduri and Desiree. The optimum dose of N, P2O5 and
K2O was 100:50:50 kg ha-1 for both cultivars. Regression of N, P2O5 and K2O doses on Kufri
Sinduri and Desiree explained 78 and 31% variation, respectively, in the tuber yield. Leaf N alone
accounted for maximum variation (76% and 43% by linear in Kufri Sinduri and Desiree,
respectively). Leaf N, P and K, respectively 5.04, 0.29 and 3.97% dry matter was critical for potato
production under humid sub-tropical condition of Chitwan. Present findings suggest that Nitrogen,
Phosphorous and Potassium fertilizers management should be based on leaf analysis for balanced
application of mineral nutrients in potato crops.Link for e-copy: http://elibrary.narc.gov.np/?r=74

Title : Evaluation of Common Nepalese Rice Cultivars Against Rice Root Knot Nematode Material Type: printed text Authors: Deepak Sharma Paudyal, Author ; Ramesh R. Pokharel, Author ; Sundar M. Shrestha, Author ; G.B. Khatri Chhetri, Author Publication Date: 2004 Article on page: 33-36 p Languages : English (eng) Keywords: Meloidogyne graminicola, Oryza sativa, resistant sources Abstract: Twelve commonly cultivated rice cultivars viz. Radha-7, Ghaiya-2, Rampur Masuli,
Bindeshwari, Makawanpur-1, Sabitri, Janaki, Chaite-2, Radha-9, Radha-4, Chaite-6 and Masuli were
tested against rice root knot nematode (Meloidogyne graminicola) in sick soil under greenhouse
condition. Resistance screening of the cultivars was done based on the
reproducibility of M. graminicola to IR-29 susceptible check and disease intensity grade was
classified on the basis of root knot index. All the cultivars were susceptible to M. graminicola
except Masuli and Chaite-6, which were moderately resistant. Ghaiya-2 and Janaki were even more
susceptible than IR-29 and these cultivars can be used as susceptible check instead of IR-
29. Since the common cultivars were susceptible to M. graminicola, it is necessary to screen more
rice cultivars to explore resistant sources against root knot nematode of rice.Link for e-copy: http://elibrary.narc.gov.np/?r=76

and agriculture is the main source of income. A study to identify soil-fertility status of land use
systems ie Bari (upland) and Khet (irrigated lowland), which are the two district and dominant
agricultural land use systems in the Hills of Nepal was carried out in Lohorne Watershed, Dailekh
District of Nepal. Soil fertility status of nitrogen (N), phosphorous (P), potassium (K) and
organic matter (OM) is better in Bari than in Khet land. The pH was found to be slightly low, more
acidic in Khet than in Bari land. Root depth and bulk density of Khet land were higher than that of
Bari land. Higher application rate of farmyard manure (FYM) in Bari land and less crop intensity

Title : Isozyme Variations in Fine and Aromatic Rice Genotypes Material Type: printed text Authors: Bimb, Hari P., Author ; Sah, Ram P., Author ; Navin L. Karn, Author Publication Date: 2004 Article on page: 59-64 p Languages : English (eng) Keywords: Fine and aromatic rice, genetic diversity, isozyme Abstract: Allozyme electrophoresis has been a reliable technique in estimating the genetic variation in
crops.
We surveyed isozyme variation of 24 aromatic and fine rice varieties collected from Nepal including
Jetho budho landrace. Five enzyme systems were analyzed for allozyme variability that detected
distinct 10 isozyme loci and 15 alleles including null alleles. The polymorphic enzyme
systems, esterase revealed 8 phenotypes, 6- phosphoglutanate dehydrogenase and peroxidase each
with 3 phenotypes and alcohol dehydrogenase and aspartate aminotransferase each with 2 phenotypes
based on the combination of presence and absence of alleles. Dendrogram did not indicate any clear
pattern of these populations into definite clusters. However 3 groups were detected at 84% of
dissimilarity among 24 populations. Nepalese varieties Rato Basmati, Pahenle and Jetho Budho

systems, esterase revealed 8 phenotypes, 6- phosphoglutanate dehydrogenase and peroxidase each
with 3 phenotypes and alcohol dehydrogenase and aspartate aminotransferase each with 2 phenotypes
based on the combination of presence and absence of alleles. Dendrogram did not indicate any clear
pattern of these populations into definite clusters. However 3 groups were detected at 84% of
dissimilarity among 24 populations. Nepalese varieties Rato Basmati, Pahenle and Jetho Budho
grouped in a separate cluster in the dendrogram.Link for e-copy: http://elibrary.narc.gov.np/?r=80
Title : Effects of Different Levels of Boron on Cauliflower (Brassica oleracea var. botrytis) Curd Production on Acid Soil of Malepatan, Pokhara Material Type: printed text Authors: Adhikary, Bishnu H., Author ; Ghale, M.S., Author ; Chiranjibi Adhikary, Author ; Surya P. Dahal, Author ; Durga R. Ranabhat, Author Publication Date: 2004 Article on page: 65-67 p Languages : English (eng) Keywords: Boron, Brassica oleracea var. botrytis, curd production Abstract: Experiments were conducted in two consecutive years (2000 and 2001) at Agricultural Research
Station, Malepatan to evaluate the effects of boron levels on cauliflower curd production. A
randomized complete block design with three replications was employed. Six levels of boron (0 kg, 5
kg, 10 kg, 15 kg, 20 kg and 25 kg borax ha-1) were tested. Fertilizers and manures were applied at
the rate of 120:60:40 kg N:P2O5:K2O and 10 tons of compost per hectare in all the plots. The
variety used in the experiment was Kibogiant. The growth (plant height, leaf numbers, leaf length
and fresh biomass production) was affected by the boron levels. The maximum plant height (42.05 cm)
was observed when the crop was supplied with 25 kg borax ha-1 which was almost
13.95 percent higher than that of non-treated control crop. Maximum leaf numbers (12.73 plant-1)
and leaf length (38.91 cm) were observed when the crop was fertilized with 10 kg borax ha-1. The
maximum biomass production (1.06 kg plant-1) was obtained with the crop treated with 25 kg
borax ha-1. The curd size (diameter) was increased with increasing levels of borax upto 15 kg ha-1.
The maximum curd diameter (10.28 cm) was produced when the crop was treated with 25 kg borax ha-1.
Highly significant effect of boron levels were observed on the curd production. The two years mean
showed an increasing curd production trend with increasing levels of borax application. The
maximum curd weight (10.9 t ha-1) was observed when the crop was supplied with 25 kg borax ha-1.
However, nonsignificant differences on curd production were observed between 15 kg, 20 kg and 25 kg
borax application per hectare.Contents note: Boron, Brassica oleracea var. botrytis, curd production Link for e-copy: http://elibrary.narc.gov.np/?r=81

Title : Red Listing of Agricultural Crop Species, Varieties and Landraces Material Type: printed text Authors: Joshi, Bal K., Author ; ,Upadhyay, Madhusudan, Author ; Gauchan, Devendra, Author ; Sthapit, Bhuwan R., Author ; Joshi, K.D., Author Publication Date: 2004 Article on page: 73-79 p General note: Review article Languages : English (eng) Keywords: Agricultural crops, conservation, on farm, red list category, red-listing criteria Abstract: Red listing mechanism has been developed for wild fauna and flora. There are several
documents illustrating red listed wild fauna and flora. But there is a lack of information on the
red list and red listing criteria of agricultural crop species, varieties or landraces. For initiating
on- farm, in situ and ex situ conservations, red listing is helpful in locating region of crop
species, varieties or landraces diversity. The paper reviewed the red listing criteria used for the
categorization of wild fauna and flora. Categorization of on-farm crop species, varieties and
landraces is based on population, ecological, social, modernization and use criteria. Among
them ecological, social and modernization criteria are useful in selecting location for sampling
materials for ex situ conservation and appropriate sites for in situ conservation. Modernization
and use criteria are suitable for categorization of crop genotypes. Combinations of these criteria
are proposed for red listing crop genotypes and areas.Link for e-copy: http://elibrary.narc.gov.np/?r=84
