Title : Participatory technology divelopment at on-farm research site in summer season Material Type: printed text Authors: SU Khan ; J.P Shriwastav, Author ; C.B Chhetri, Author ; N.K Bista, Author Pagination: 382-389 p. Languages : English (eng) Abstract: Rice is an important crop ofTiflestern Terai, but rice .yields are low compared to its potential.
To improve rice yield, different field experiments were conducted in three different sites
namely Sand:2, Mahilawar and Burrohiya, command area of National Whea~ Research
Program, Bhairahawa. The activities were concentrated on rice varietal improvement;
agronomic aspects and validation of improve technologies. In coordinated farmers' field trial
at Mahilwar site, BPI 3-2 produced significantly higher grain yield (4600 kglha) than rest of
the tested genotypes, whereas genotypes IR 58115-103-3-1-1 and BR 4684-13-1-1-6-3 were
at par to each other and were significantly higher than PSBRC-2 and Sabitri. However at
Burrohiya site, genotypes B6144F-MR-6 and Radha-4 were at par to each other and
produced significantly higher grain yield than rest of the tested genotypes. In Coordinated
Farmers Field Trial of aromatic rice, highly significant variation for grain yield was
recorded which raged .from 3600 to 4300 kglha at Mahilwar site and 4000 to 6166 kg/ha at
Burrohiya site. At Burrohiya site, genotype CNTLR85033-9-3-1-1 produced significantly
highest grain yield (61 66 kg/ha) amongst the tested genotypes. The yield peiformance of rice
genotypes tested in FAT at Sanda site, the mean grain yield of genotypes NR 1824 and
BR425-189-1-6-2-1 showed higher (4300 and 4367 kglha respectively) yield than other
tested genotypes. Whereas at Mahilwar site, genotype BR 802 produced the highest mean
grain y ield (4000 kg/ha) and was liked by the farmers. Under rainfed low land condition at
Burrohiya site, genotypes BR 425-189-1-6-2-1 produced the highest mean grain yield (5225
kg/ha) and was preferred by the farmers. In study of System of Rice Intensification (SRI), the
mean grain yields of Radha-4 at sanda was higher (5266.5 kglha) compared to farmers
practice (3950 kglha). At Bun·ohiya site, variety Sabitri produced higher grain yield (7055
kglha) compared to fanners practice (4000 kg/ha.). Result of Frontline Demonstration
conducted in deferent environment showed that with recommended practices higher grain
yield up to 5600 kglha could be achieved with genotype B6144-FMR6-2 under farmer's
field condition.Link for e-copy: http://elibrary.narc.gov.np/?r=1126 Participatory technology divelopment at on-farm research site in summer season [printed text] / SU Khan ; J.P Shriwastav, Author ; C.B Chhetri, Author ; N.K Bista, Author . - [s.d.] . - 382-389 p.

Title : Testing and evaluation of different methods of rice transplanting Material Type: printed text Authors: SU Khan ; Regmi, A.P., Author ; N.K Bista, Author Pagination: 221-227 p. Languages : English (eng) Keywords: cropping system ; cereal soil fertility Abstract: All size farmers are experiencing labor shor(age in paddy .season, especially during rice
transplanting. This study was conducted to find out . alternatives of traditional manual .
transplanting method Manual and power rice transplanter and System of Rice Intensification
(SRI) technique with single and double seedling of rice was used with mat -type rice seedling
raiSing in puddle soil. This technique has created better condition for water and weed control and
allows 15-20 days earlier planting of seedling and reducing the inherent drudgery in manual
transplanting. Farmer practice is very labor intens.ive, requiring about 30-35 labors per day per
hectare for transplanting. This high labor input often results in labor shortages during rice
trahsplanting season. Among the tested four methods of rice transplanting, both SRI with single
or double seedlings per hill produced mean yield of6209 kglha that was significantly higher than
other methods of transplanting. Mean rice grain yield was recorded as 3003 kglha with a range
varying from 2437 to 4012 kglha with manual rice transplanting machine in farmers field that
was similar with yield of farmers practice. Farmers interview revealed that about 15 labors are
required to transplant one hectare by traditional transplanting method, while manual operated
transplanting machine needs only 8 labors for the same operation in one day. Additional saving
are made with the seedbed where the traditional method takes 18 local labors per day to uproot
and bundle the seedlings for one hectare, while mat-nursery needs only four person in one day to
cut seed mats for one hectare. Restated, under farmer's condition, it takes 43 people per hectare
per day to transport seedlings to the main rice fields. Feedback from the farmers showed that
machine was the best option to reduced the drudgery of planting rice.Link for e-copy: http://elibrary.narc.gov.np/?r=1107 Testing and evaluation of different methods of rice transplanting [printed text] / SU Khan ; Regmi, A.P., Author ; N.K Bista, Author . - [s.d.] . - 221-227 p.
