Title : Alternative technique of rice transplanting Material Type: printed text Authors: Ganesh Sah ; Sah, R.P., Author Pagination: 412-417 p. Languages : English (eng) Abstract: The experiments were conducted at the Agricultural Implement Research Centre (AIRC),
Birganj during Kharif seasons 2000101 to 2002103. The experiments consisted of 3
treatments during first year and 4 treatments in the following years. The treatments were:
seed dropping by Drum Seeder with 20 x 15 em spacing (T1), seed dropping by Drum Seeder
with 20 x 20 em spacing (T;) , seed dropping by Drum Seeder with 20 ems x continuous
spacing (T J), and Manual Transplanting (T-4). Germinated seed of rice variety Radha-4 was
dropped on the surface of puddled and leveledfields. Rice grain yields (at 1-1% m.c.) were,
during first two years, at par, while. they were significant in the last year. The highest mean
grain yield of. over the years, 5833 kglha was produced by treatment T3. While, manual
transplanting of seedlings (T-4) produced the lowest mean grain yield of 5055 kglha. Straw
yields produced by the treatments varied significantly during the years. The highest mean
straw yield of 7713 kg/ha was produced by treatment (T ;). Treatment T1 showed the lowest
mean straw yield of 7314 kglha. The highest mean marginal return of 39701.00 Rs/ha was
seen with treatment (T;) and the lowest of31 79 2. 00 Rslha by manual transplanting. Seed

Title : Evaluation of low cost direct seeded rice technologies in farmer's field Material Type: printed text Authors: Ganesh Sah ; Pratap Ram Sah, Author Pagination: 390-396 p. Languages : English (eng) Abstract: The on-farm evaluation of Low Cost Direct Seeded Rice Technologies :was conducted at
Belwa VDC, Parsa district and Fattepur VDC, Bara district during Kharif seasons, 2000101
to 2002103. The experiments consisted offour treatments duringfirstyear andjive treatments
during last two years. The treatments were : Direct Seeded Rice on !:-eds (dry-seed) by FIRB
(T,), Direct Seeded Rice on flat (d1y seed) by Power Tiller Drill (T j, Direct Seeded Rice on
puddled flat fields (germinated seed) by Drum Seeder (I J), Manual Transplanting on
puddledfl.atfields i.e. Farmer's Practice (T.J and Manual Transplanting on beds formed by
FIRB (1'5). Grain yields produced by the treatments were not significant in first year, while,
they were highly significant in last two years. The highest mean grain yield of 4352 kglha
was produced with treatment T; and the lowest of 3536 kglha with treatment T5. Straw yields
were highly significant in last year, while, they were at par in first two years. The highest
mean straw yield of 8209 kglha was found with treatment T3 and the lowest of 5818 kglha
with treatment T5. Economically, Direct Seeded Rice by Drum Seeder showed the highest
marginal return of29111 Rslha, while, Direct Seeded Rice by FIRB, (T1) . (27427 Rslha) and
by Power Tiller Drill (1'1), (27366 Rs/ha) were equally good. Manual Transplanting on beds
showed the least marginal return of 21795 Rslha . Compared to Manual Transplanting on
flat (F.P.), Direct Seeded Rice by FIRB and Power Tiller Drill consumed lesser water
without disturbing the soil microbial activities.Link for e-copy: http://elibrary.narc.gov.np/?r=1127 Evaluation of low cost direct seeded rice technologies in farmer's field [printed text] / Ganesh Sah ; Pratap Ram Sah, Author . - [s.d.] . - 390-396 p.

Title : Recovery of 15th applied and crop yields of rice and wheat with tillage and crop management practices under Rice-wheat cropping system in Parsa, Nepal Material Type: printed text Authors: Ram C Munankarmy, Editor ; Ganesh Sah, Author Publication Date: 2010 Pagination: 442-454 p. Abstract: An experiment with tillage and crop establishment methods was carried out with collaboration from TAEAIFAO in Ranighat, Parsa,
Nepal from 2002/03 to 2005/06 cropping cycle for exploring the nitrogen use efficiency in rice and wheat crops under new tillage
system. Four treatments were included in the study- l.a conventional practices for rice and wheat (PTF/Clj, 2. transplanting rice in
unpuddled bed and subsequently seeding wheat with minimum till drill without distuming the bed made for rice (UPTB/D), 3.
seeding rice directly in flat field and subsequently seeding wheat with minimum till drill (UPDF/D), and 4. seeding rice in bed with
paired rows without puddling and subsequently seeding wheat with minimum till drill on bed (UPDB/D). 15 N-labe1ed urea (5
atom%) was used to supply 100 and 120 kg N/ha for rice and wheat respectively to separate micro-plots of 1.0 m x 0.8 m for flat and
1.2 m x 0.65 m for bed. Mean rice grain yields were significantly higher at PTF/CT over new practices tested. Transplanted rice gave
higher yield as compared to direct seeded rice in both bed and flat systems, but the yields between the bed and flat system within the
planting method were insignificant. Similarly, significantly higher wheat yields were found at PTF/CT over rest of the treatments.
Both rice and wheat yields were found to be decreased as the years advanced. Mean rice straw yields were insignificantly different
but wheat straw yields were significantly higher at PTF/CT over other treatments. Mean N03-N at tillering stage of rice was
significantly higher at UPDF/f' & UPDB/D than in transplanted rice in all three depths but not different at harvest. N03-N decreased
with increase in depth at both stages. In wheat, mean N03-N measured at jointing stage were found to be significantly higher at bed
than at flat within the same crop establishment method at 0-15 em depth, but similar trend was not found in other depths and at
harvest. Mean NH4-N at tillering as well as at rice harvest was not significantly different due to treatments in all three depths. Again,
the nitrogen variation with depths was not observed at both stages of rice crop. In wheat, NH4-N at jointing stage was significantly
higher at UPDB/D over other treatments at 0-15 em depth, and the level decreased with the increase in sampling depth. Significantly
higher recovery of applied 15N in rice plant was observed at PTF/CT (45.8%) over other treatments but the recovery was not
different in soil. Similarly, in wheat plant significantly higher recovery of 31.1% was observed at PTF/CT over UPDF/D but in soil
higher recovery was observed at UPTB/D over PTF/CT& UPDF/D. Mean of the treatments and the years, 38.1% of the applied 15N
was recovered in rice plant of which 23.8% in grain & 14.7% in straw, and 16.6% in soil. In wheat crop, 26.0% was recovered in
plant of which 20.7% in grain & 5.3% in straw, and 22.7% in soil. Mean N uptake by rice crop was significantly higher at PTF/CT
over UPTB/D & UPDB/D. Mean N uptake by rice was found to be 107 kg /ha, .of which 66.2 kg by grain and 40.7 kg by straw. In
wheat, N uptake was higher at PTF/CT than at UPTB/D & UPDB/D. Total N uptake by wheat was found to be 68.4 kg/ha of which
53.0 by grain and 15.4 by straw.Link for e-copy: http://elibrary.narc.gov.np/?r=1050 Recovery of 15th applied and crop yields of rice and wheat with tillage and crop management practices under Rice-wheat cropping system in Parsa, Nepal [printed text] / Ram C Munankarmy, Editor ; Ganesh Sah, Author . - 2010 . - 442-454 p.
