Agronomical investigation on drought tolerant rice in mid-western Terai of Nepal / Krishna Kumar Mishra
in Proceedings of the 27th National Summer Crops Workshop, held at Rampur, Chitawan, 18-20 April 2013, Vol. I / Giri, Y.P.
Title : Agronomical investigation on drought tolerant rice in mid-western Terai of Nepal Material Type: printed text Authors: Krishna Kumar Mishra Pagination: 229-240 p. Languages : English (eng) Keywords: Drought tolerant rice ; water scarcity Abstract: Drought is the major constraint to rice production in rain fed areas ofNepal. In the context of
current and predicted water scarcity, increasing irrigation is generally not a viable option for
alleviating drought problems in rain fed rice-growing systems. It is therefore important that
agronomic and genetic management strategies should be followed for drought focusing on
maximum extraction of available soil moisture and its efficient utilization in crop
establishment and growth to maximize biomass and yield. A field experiment was conducted
during rainy season of 2011 to 2012 at Regional Agriculture Research Station, Nepalgunj
with an objective to find out the nutrients requirement of rice and the interaction effect
between nutrient and genotypes. Similarly, age of seedlings experiment with an objective of
studying the genotype effect, age of seedling effect and their interaction effect in drought
tolerant genotypes of rice was conducted. The trust was given to select genotypes with
different age of seedlings which perform well under a range of transplanting condition. The
yield differences recorded on different treatments in nutrient management. Grain yield
obtained at 90: 60 : 40 kg N, P205 and K20 /ha was statistically significantly superior over
control and 45 :30:20 kg N, P205 and K20 /ha. Interaction effect of different nutrients levels and
genotypes on grain yield was found significant, Rice genotypes impacted grain yield when
averaged over the nutrient Level. IR83388-B-B-108-3 (4360kg/ha) produced the highest mean
grain yield followed by, IR83383-B-B-129-4 (4278kg/ha) and IR83383-B-B-129-3
(4185kg/ha). Age of seedling impacted rice grain yield significantly, The overall mean grain
yields obtained from different seedling age revealed a 61.83 kg/ha/day yield loss up to 35
days old seedling planting whereas 45 days old seedling planting caused 65 .29 kg/ha/day
yield loss compare to 25 days old seedling transplanting. Similarly rice genotype impacted
rice grain yield when averaged over the age of seedling. IR83383-B-B-129-3 produced the
highest mean grain yield (4310 kglha) followed by IR83388-B-B-108-3(3843 kg/ha) and
IR83383-B-B-129-4 (3 711 kg/ha) respectively. Rice genotypes interacted with seedling age in
producing rice grain yields. Change either in seedling age or in rice genotypes would impact
rice grain yields. IR82589-B-B-84-3 , IR80463-B-39-3 and Sukha Dhan 1 were stable
genotypes in producing grain yields up to 35 days old seedling as no significant reduction in
grain yield was seen but after 35 days, yield were reduced significantly in all genotypes.Link for e-copy: http://elibrary.narc.gov.np/?r=902 Agronomical investigation on drought tolerant rice in mid-western Terai of Nepal [printed text] / Krishna Kumar Mishra . - [s.d.] . - 229-240 p.

Title : Development and identification of cold tolerant rice genotypes for high hill areas of Nepal Material Type: printed text Authors: Upreti, H.K., Editor ; Khatiwada, S.P. ; J.B Adhikari, Author ; RB Bhujel, Author ; P Mahat, Author Pagination: 115-119 p. Keywords: Cold tolerant ; cold injury rice genotypes high hills livelihood Abstract: Rice (Oryza sativa L.) is the staple food crop of Nepal occupying area of about 1.5 million
hectare from 60 meter in terai to 3050 meter above sea level in high hill Jumla with the
productivity of 3.13 tlha. About 4.46% of the total rice land falls within high hill where
cold injury due to low air temperature is the major constraint in the rice production. An
attempt was made to develop cold tolerant and high yielding rive genotypes for this region
by conducting on station and on farm rice varietal research. On station research were
conducted at ARS Jumla and Khumaltar late planting condition involving 10-12 rice
genotypes during 2009-2012 in randomized complete block design (RCBD). Four
promising lines were evaluated in the farmer's field as on farm trial in OR sites of ARS
Jumla, and ARS Pakhribas during 2009-2012. These lines were compared with standard
check variety Chandannath-3. Among them NR10479-B-33-2-1-1 and NR10482-B-10-3-2-
2 were found promising and preferred by farmers due to its stable high yield over
Chandannath-3 in tested locations. Release and wider dissemination of these genotypes will
help to uplift the livelihood of high hill farmers' and help to reduce the problem of food
security in high hill areas.Link for e-copy: http://elibrary.narc.gov.np/?r=938 Development and identification of cold tolerant rice genotypes for high hill areas of Nepal [printed text] / Upreti, H.K., Editor ; Khatiwada, S.P. ; J.B Adhikari, Author ; RB Bhujel, Author ; P Mahat, Author . - [s.d.] . - 115-119 p.

Keywords: Genotypes ; grain yield agro-environments production rice cold tolerant Abstract: A number of experiments were carried out to identify high yielding genotypes of rice for river basin, foot and mid hills agro
environments of western hills in 2004. Genotypes of spring rice namely IR 57893-10 (4.6tlha) and NR 1969-51-5-2-6-2 (4.4 tlha)
were found promising for river basin agro-environments. Similarly, NR 10414-34-2-3 (3.8tlha), NR 10439-28-l-l-1(3.6t/ha) and NR
I 0414-25-2 (3.5 tlha) genotypes of normal rice were also found promising for the same agro-environments. Out of the tested
genotypes of normal rice for foothill, NR 1487 and NR 10353-8-2-1(3.8tlha) genotypes were found promising. NR 10395-16-2-2-
1 (5 .1 tlha), BG 1442 (5 .0 tlha and NR I 0353-8-2-1 (4.9tlha) genotypes were found superior for mid hills. A coordinated varietal trial
was also conducted in mid hill agro-environment. The genotype NR 10492-7-2-2 (4.9tlha) and NR 10342-29-2-2 (4.6 tlha) identified
as promising for mid hills. Similar types of experiments were also conducted during 2005. Genotypes namely OR 367, NR 1835-2-
1-2-2-1-4, BR 6158-RWBC2-6-8 and NR 176-6-43-3-3-2-1 were found promising with the average grain yield of 5.0- 5.5 t/ha for
normal irrigated condition of river basin. Whereas, lR 59539-2 (7.8 t/ha), lET 3137 (7.6 t/ha), Radha-4 (7.2 t/ha) and BPI 49F
(5.9tlha) were found promising genotypes for the rainfed condition of the river basin. FRX 30 5F6Bl-8 (5250 kg/Ita) and lR 69745-
251-2-2-1-1 ( 4~ 17 kglha) genotypes of fine and aromatic rice were identified as superior for 1iver basin. Genotypes namely NR
10414-34-2-3 (6.7 tlha), NR 10353-8-2-1 (6.4 tlha) were found promising for mid hills and preferred by the farmers. LR 91006
(5116 kglha) and LR 93015 (4901 kglha) were found promising genotypes for cold tolerance in high hills. Statistically, the
