• Finger millet is the fourth most important cereal crop of Nepal in terms of area and production
• Despite having tremendous potential for food and nutrition security finger millet is neglected by the National
• Interest among farmers on finger millet cultivation is declining due to agronomic, social and cultural factors
• Realizing the value of the crop, through IDRC and DFATD funded initiative “RESMISA”, we tried to identify the constraints and potential of finger millet cultivation in Nepal
Background
![Page 3: Sustainable Food Production: Improved agronomy: Option for raising the interest of finger millet farmers in Nepal](https://reader033.fdocuments.us/reader033/viewer/2022060206/55a252401a28abdd758b46cd/html5/thumbnails/3.jpg)
• A survey named as “Sustainable Agriculture Kit survey” revealed that raising nursery, transplanting, weeding and harvesting were highly labour consuming
• The study also showed that women contributed to the majority of work involved in finger millet cultivation
• We tested different on-farm experiments to identify the labourreducing and women friendly agronomic interventions and also tested different machineries
Background…
![Page 4: Sustainable Food Production: Improved agronomy: Option for raising the interest of finger millet farmers in Nepal](https://reader033.fdocuments.us/reader033/viewer/2022060206/55a252401a28abdd758b46cd/html5/thumbnails/4.jpg)
• Finger millet is relayed with Maize in high hills and as mono-crop in the foot hills. We considered maize in the agronomic interventions since the testing sites fall under maize-finger millet relay cropping system.
• Varieties: Finger millet- Kabre Kodo 1, Maize- Manakamana 3
Experiments
• Direct seeding of finger millet
• Line sowing of maize and line sowing of finger millet
• Line sowing of maize and line transplanting of finger millet
• Line sowing of maize, line transplanting of finger millet and intercropping of legume in finger millet
Methodology
![Page 5: Sustainable Food Production: Improved agronomy: Option for raising the interest of finger millet farmers in Nepal](https://reader033.fdocuments.us/reader033/viewer/2022060206/55a252401a28abdd758b46cd/html5/thumbnails/5.jpg)
• All the experiments were single replicated i.e one farmer as one replication
• Each experiment had a single block with two plots i.e. one test plot and the other control
• Maize spacing (75 cm x 25 cm) and finger millet (15cm x 10 cm)
• Farmers’ feedback collected through group discussions and survey
Testing small machines/hand tools
• Auto-seeder tested in trials and a few farmers’ plots
Methodology

• Plant population in the test plots was less than 3 times lower than the farmers’ practice leading to low yield (N= 5)
![Page 15: Sustainable Food Production: Improved agronomy: Option for raising the interest of finger millet farmers in Nepal](https://reader033.fdocuments.us/reader033/viewer/2022060206/55a252401a28abdd758b46cd/html5/thumbnails/15.jpg)
Group discussions and survey study showed that
• Line transplanting makes weeding easy and requires less
• Maintenance of proper spacing important to increase yield
• 45% women and 61% men showed interest to try line transplanting in the following year

• 44% more economic benefit was observed
• Cowpea not preferred as intercrop due to its growth habit

Perception of farmers on auto-seeder
• In 2014, More than 70 farmers have tried auto-seeder in their plots ranging from almost from 300 m2 to 1500 m2.

• It reduces the cost of labourand draft power
• It can be handled by women and children very easily
• Maize can be sown in line with this machine
• The machine can be adjusted and can be used for other cereals
General feedback of farmers on auto-seeder
![Page 22: Sustainable Food Production: Improved agronomy: Option for raising the interest of finger millet farmers in Nepal](https://reader033.fdocuments.us/reader033/viewer/2022060206/55a252401a28abdd758b46cd/html5/thumbnails/22.jpg)
• Direct seeding method in finger millet is appropriate in mono-cropping conditions but not in relay crop with maize
• Line transplanting of finger millet seedlings as a relay crop to maize appears more promising than traditional method of transplanting
• Economic benefits clearly demonstrated benefit of intercropping legumes in finger millet
• Maize auto-seeder helps line sowing of maize which in turn facilitate line transplanting in finger millet leading to reduced drudgery and efficiency in weeding
Conclusion
