CIMMYT-Bangladesh

Collaborative Projects1. Addressing constraints to pulses in cereals based

cropping systems in North West BD (March, 2011)

2. Expanding the area for Rabi-season cropping in southern BD (April, 2011)

3. Abiotic stress tolerant in maize (June, 2011)

4. Accelerating seed multiplication to combat the threat of stem rust in wheat (2011)

5. Sustainable intensification of R-M production systems (2013)

6. CSISA - a mega project– Objectives 1, 2 (2.1, 2.2), ● New CSISA Expansion – (September, 2015).

Addressing constraints to pulses in cereals based cropping systems in North West BD

● Successfully demonstrated the cultivation of lentil and chickpea in high barind track

● Awareness creation about multi-crop planters (VMP)

● Low cost strip and zero till planters improved and tested for a range of crops and soils

● Mini-mill prototype designed and demonstrated

● Operators training on the use of multi-crop planters and mini-mill prototype conducted successfully

Expanding the area for Rabi-season cropping in southern BD● About 200,000 ha of land in SB lie fallow in winter

Government support for wheat was not encouraging Salinity and terminal heat – major constraints

● Varieties identified – relatively tolerant to salinity and higher temperature during grain filling stage (e.g. BARI Gom 25) through PVS

● Wheat in southern BD with acceptable yield (2.5 t/yield even planted under late condition i.e. up to 15 December)

● Learning from this project are integrated into the CSISA expansion in BD

Abiotic stress tolerant maize for increasing income and food ● Evaluation of Maize

Cultivars under different tillage systems

two factors (Tillage method= A; Variety = B) Strip Tillage Bed planting

● Establishment study of hybrids under different moisture regimes – using planter

● Publications

Accelerating seed multiplication to combat the threat of stem rust in wheat

Objectives

To ensure fast replacement of existing commercial varieties that are vulnerable to new races of stem rust (Ug99) through accelerated seed multiplication and dissemination of new rust resistant varieties working with NARS, national seed programs and farmers

USAID Seed ProjectUSAID Seed Project

Progress1. Bangladesh - BARI Gom 26 (BAW 1120 i.e.

Francolin, V01078) 2. Nepal – Vijaya (Francolin)3. Afghanistan – Chonte, Misr 1 (Misr 2, and

3) - massive scale 4. Egypt – Misr 1, Misr 2. 5. Pakistan – (V04178 – Released?)6. Ethiopia – Danda a (Picaflor#1) -Middle

elevation, Kakaba (Danphe#1) -higher elevation

1. Government is very supportive to multiply these varieties in a massive scale.

●Activities - Decentralized PVS and

Adaptive trials – Both varietal and CA based CM

Seed production – marketing and distribution

A. CA based demonstrations using Ug99 resistant lines/varieties

● Possible combinations for CA demonstrations (few examples):

Raised bed vs flat sowing (30% residue) Strip till vs flat sowing (30% residue)

● Machine Operators’ training ● CA based adaptive diamond trials - Wheat -

rice - maize/mungbean pattern.

B. Variety cum CM trials

Treatments

1. Factor A = Variety (V) 1. Improved (Ug99 Resistant) (V1)

2. Adapted Local (V2)

2. Factor B = Crop Management (M)1. CA Based Technology (M1)

2. Farmers management (M2)

SummarySummary Increased awareness among R &D leaders

Stem Rust (race Ug99) is a devastating disease Significant progress have made to mitigate the

threat Release better varieties - urgently needed There are still some challenges.

Sustainability of large scale seed multiplication and seed marketing

Buy back of pre-release seed by private companies

Affected multiplication of pipeline varieties Varieties resistant to Ug99 are not always

outperforming established varieties

Sustainable intensification of R-M production systems

Objectives● Assess and prioritize constraints to, and opportunities

for, uptake of improved management options in R-M systems

● Evaluate and identify elite maize germplasm tolerant of excess moisture

● Develop locally adapted management solutions for high-yielding, profitable, resource-efficient, and sustainable R-M systems (CA & nutrient management)

● Build capacity and disseminate key technologies for R-M systems

Progress

● Capacity building of researchers and field/scientific assistants on all aspects of the experiments

● Increased awareness about CA among researchers and field/scientific assistants, farmers, govt. and non-govt. officials, and media persons

● Introduced seeding machinery and CA practices in farmers’ fields in completely new areas (e.g. Comilla, Rangpur, Paba-Rajshahi)

● Improved understanding of crop responses to N, P, and K through NM evaluation and omission plot trials across project sites

● Variability among maize hybrids on water logging tolerance

Future focus● Analysis, synthesis and interpretations of those

data and write-up, including economic analysis● Continue emphasis on CA based Crop

Management and NM evaluation trials for maize ● Refine the NM software for Rice and Maize● Focus on dissemination activities (improved

seeds, large-scale delivery of maize and DSR with PTOS and zero/strip tillage, etc.) -> inclined plate device

● Focus on communication activities (brochures, etc.)

New CSISA Expansion in B/Desh● CIMMYT, IRRI, WorldFish● 5-year investment from USAID – Bangladesh

(FtF- $24.4 m)● Enterprise-based diversified strategy● Emphasis on technology delivery, capacity

building, and adaptive research (no upstream research, breeding, or policy)

● Formation of four new hubs in the South BD● Strengthening of existing hubs in Central and

Northwest (3X more resources at hubs)

CSISA Hubs in Bangladesh

Existing hubs :•Dinajpur (Rajshahi satellite)•Central BD (Gazipur → Mymensingh)

New hubs for 2011 :•Jessore•Khulna•Barisal

New hubs for 2012 :•Noakhali

What has worked● Strip till – maize, wheat and

legumes● Bed planting – wheat, maize ● Training

Machine operators training Whole family training

What hasn’t worked well

●Service provider concept●Encouraging local manufacturers●Residue management
