Title : Conservation agriculture: A system for sustainable food production Material Type: printed text Authors: G Sah, Author ; G.B Manandhar, Author ; Adhikary, S.K., Author ; J. Tripathi, Author Pagination: 65-72 p. Languages : English (eng) Abstract: Conservation Agriculture (CA), defined as minimal soil disturbance (no-till) and permanent soil cover (mulch) combined with rotations, is more sustainable cultivation system for the future than those practiced these-days. Present tillage system is responsible for the degradation of natural resources and soils. CA can improve agriculture through improvement in water infiltration and reducing erosion, improving soil surface aggregates, reducing compaction through promotion of biological tillage, increasing surface soil organic matter and carbon content, moderating soil temperature, and suppressing weeds. CA also helps reduce cost of production, saves time, increase diversity, and reduces greenhouse gas emissions. Availability of suitable equipment is a major constraint to successful CA. National promotional program for this technology is needed in present Nepalese context.

Title : Crop residue management in sustaining production of rice-wheat system Material Type: printed text Authors: J. Tripathi, Author ; T.P Kharel, Author ; Duxbury J.M, Author ; N.K Shakya, Author ; J Lauren, Author Pagination: 166-173 p. Languages : English (eng) Abstract: An experiment on crop residue management in rice-wheat system conducted for four successive years ( 1998/99-200 I /02) revealed that residue incorporation with recommended N PK increased both grain yield of rice and wheat crops when 20 kg additional nitrogen was applied at the time of straw incorporation. Mulched treatment with recommended N PK a so produced better yield in both rice and wheat crops. Residue incorporated with recommended N PK only produced similar or less yield to that of recommended NPK treatment only. However, the effects of residue management were seen only after the second year. Thus it is expected that residue management in rice-wheat system will be beneficial in the long run to improve productivity and sustainability of the rice-wheat system.

Title : Direct seeding : an emerging resouce conserving technology for rice cultivation in the rice-wheat system Material Type: printed text Authors: J. Tripathi ; Bhatta, M.R., Author ; S Justise, Author ; N.K Shakya, Author Pagination: 273-283 p. Languages : English (eng) Abstract: (DSR) has emerged as a viable alternative to transplanting (l'P R). Direct seeding with
different RCTs equipments such as power tiller drill (PTD) and zero till drill (ZTD) improved
the yield potential of DSR coupled with additional advantages of reduced or zero till system
for improved productivity, profitability and sustainability of the rice-wheat system.
Several experiments were conducted during 2002103 and 2003104 in the farmer fields of
Rupandehi districts following the participatory approach to evaluate the performance of
different DSR over conventional TP R. An experiment conducted in different farmers 'field in
2002103 revealed that PTD-DSR produced significantly higher yield over HBD-DSR (hand
broadcasted dry DSR) and marginally higher than the conventional TPR and HBW-DSR
(hand broadcasted wet.DSR). A couple of DSR experiments were conducted in the last rice
season (2003/04) on RCTs along with other methods of DSR and TP R. In one experiment
PTD-DSR was compared with Wet-DSR and conventional TPR and in other one ZTD-DSR
was eva.7;'.Qted with TPR including two rice varieties (Radha-4 and Sabitri). In first
experiment, PTD-DSR was found significantly superior to TP R and marginally superior to
HBW-DSR. In second experiment, ZTD-DSR proved significant superiority over TPR with
both of the varieties. However, Radh-4 produced comparatively higher yield than Sabitri in
both ZTD-DSR and TPR. Partial budgeting based on farmers interview and crop cut
sampling of above practices revealed that PTD-DSR, ZTD-DSR and HBW-DSR provided
33%, 22% and 21% higher net return respectively as compared to conventional TPR. The
higher economic return from all three direct seeding methods attributed to saving in total
variable costs and higher yield. Direct seeding with RCT equipments proved beneficial as
compared to conventional TPR qnd HBD-DSR. Broadcasted wet DSR (HBW-DSR) could
also be a viable option in the case where, RCT equipments are not available.Link for e-copy: http://elibrary.narc.gov.np/?r=1112 Direct seeding : an emerging resouce conserving technology for rice cultivation in the rice-wheat system [printed text] / J.
