Date: October 27-31, 2014
The document summarizes findings from a study on rice farming systems in Nepal. It found that the System of Rice Intensification (SRI) method produced higher yields than conventional methods. Key factors for SRI's higher yield were using younger seedlings, fewer seedlings per hill, wider spacing, and intermittent flooding irrigation. However, SRI adoption remains limited due to factors such as labor availability, irrigation access, and distance to fields. Farmers adapt their rice farming practices based on their local resources and conditions.

Ram Bahadur Khadka presented research on the System of Rice Intensification (SRI) method at a 2012 agricultural convention in Nepal. Experiments showed that younger (8-day old) seedlings planted at 25cm x 25cm spacing yielded the highest production and economic returns. The research concluded that SRI techniques can maximize rice production and contribute to national food security when adopted by small-holding farmers in Nepal. The national agricultural research system was encouraged to further test and adapt SRI to more of Nepal's climate regions.

This document outlines research on the System of Rice Intensification (SRI) in Nepal. SRI is a method that promotes more productive rice plants through changes in plant, soil, water and nutrient management. Research in Nepal has found SRI can increase yields per unit of water, seed and fertilizer used. Institutions in Nepal have been conducting research on SRI since 1998, evaluating factors like varietal selection, spacing, age of seedlings and water management. Studies have found SRI can increase yields over conventional methods by 28-50%, using fewer inputs. Ongoing research focuses include water budgeting, heavy metals, soil microbiology, greenhouse gases and mechanization. Further research and collaboration between institutions is needed to

The document discusses the System of Rice Intensification (SRI) practices for growing rice. SRI focuses on improving soil conditions and plant growth through young seedlings, wide spacing, soil aeration, and organic matter addition. Key practices include transplanting young seedlings 8-12 days old in a square pattern with wide spacing, mechanical weeding, and water management to keep soil aerobic. SRI can result in higher yields with fewer inputs through increased root and soil organism growth. Farmers are encouraged to experiment and innovate with SRI methods to suit their local conditions.
The document compares conventional rice cultivation practices to the System of Rice Intensification (SRI) method. It summarizes farmers' conventional practices, including high seeding rates and random planting, and their disadvantages like uneven growth and increased disease risk. SRI methods like younger seedlings, wider spacing, and mechanical weeding are described as improving root growth, increasing yields from 5-7 tons/hectare up to 6-8 tons/hectare, and making the crop less vulnerable to drought. The document also proposes a modified SRI method called Direct Planting System that eliminates the need for nurseries by broadcasting sprouted seeds and thinning manually.

Authors: Debashish Sen, C. Sambhu Prasad
The document summarizes experiences with the System of Rice Intensification (SRI) method in Medak District, Andhra Pradesh, India over 6 seasons from 2003-2006. 84 farmers tried SRI, with 3 continuing to use the method and 1 farmer trying it for 3 or more seasons. The majority (70) only practiced SRI once. A variety of rice varieties were planted using SRI methods. Key lessons included increased awareness of SRI, farmers being convinced of the low seed rate, and low pest and disease incidence, but also a need for more training on nursery raising, planting techniques, and water management. Weed control also required modification depending on soil type.
The document summarizes the System of Rice Intensification (SRI), an agricultural method developed in Madagascar that can double rice yields while reducing water usage, costs, and environmental impacts. SRI involves transplanting young seedlings with wide spacing, keeping soil well-aerated through alternate wetting and drying, and frequent weeding. Trials in multiple countries show SRI can increase yields from 2-4 tons/hectare to 5-10 tons/hectare or more through synergistic effects on root and tiller growth. The document discusses scientific explanations for SRI's performance and responses to objections about its adoption and labor requirements.

This document discusses the System of Rice Intensification (SRI) method of rice cultivation and the role of agricultural engineers. SRI aims to maximize rice production through practices like younger seedlings, wider spacing and less water. It encourages farmer participation and innovation. Agricultural engineers can help develop machinery to support SRI, such as transplanters for single or double seedlings, mechanized markers for spacing, and manual or powered weeders. Future work includes developing transplanters and self-propelled weeders suitable for SRI methods.
IRJET- Design and Manufacturing of Onion Plantation MachineIRJET Journal
This document describes the design and manufacturing of an onion plantation machine. The machine was created to improve planting efficiency and reduce labor involved in manual planting. It allows for planting of small seeds like onions at a variable depth and spacing between seeds. The machine is made of durable and affordable materials for small-scale farmers. It has several functional components including a frame, seed tubes, and a plant rotor for uniform planting. The machine offers advantages like improved crop yields, reduced labor needs, and more accurate seed placement compared to manual planting methods. The overall goal is to increase productivity and benefit small farmers through mechanization of the planting process.
A transplanter is an Agriculture machine used for transplanting seedlings to the field. This is very important as it reduces the time taken to transplant seedlings (when compared to manual transplanting), thus allowing more time for harvesting. It also reduces the use of manual energy. Paddy transplanter machines are comes in 2 , 3 , 4 up-to 6 rows for large capacity field .

INTSORMIL researchers are working to increase yields and profits for African sorghum and millet farmers. They are updating traditional farming methods like tilling and planting techniques. Research shows these new techniques can increase yields by 3 times compared to traditional methods. Specifically, INTSORMIL recommends practices like deep tilling and skip-row planting. However, many farmers still use traditional hand-hoe tilling and whole field planting because rural areas often lack markets for excess grain, so there is little incentive for farmers to adopt new techniques. INTSORMIL researchers are now working to establish local markets to incentivize farmers to use their yield-enhancing practices.

This document discusses gender dimensions and training needs of farm women in the system of rice intensification (SRI) in Bihar, India. It finds that SRI requires intensive labor, especially for land preparation, crop care, and water management during initial adoption. Women make up a large portion of the agricultural workforce in India. The study assessed the training needs of farm women for SRI activities like seed preparation, transplanting young seedlings, and weeding. It found that line sowing was seen as a new, highly skilled activity. The document concludes that there is potential to train self-help group women to form an SRI task force to help spread adoption and that collective action through these groups can facilitate training and faster S
DESIGN ANALYSIS AND FABRICATION OF MANUAL RICE TRANSPLANTING MACHINE | J4RV4I...Journal For Research
Need of rice transplanting machine is growing nowadays because of unique feature seeding in well sequence and well manners. This will save too much efforts of human being. Class of people who uses this kind of machine is farmers and they are having poor economic background. To feed growing population is a huge challenge. Importation of rice will lead to drain out the economy of the country. Mechanization of paddy sector will lead to higher productivity with releasing of work force to other sectors. The objective of this project is to design a paddy transplanting mechanism to transplant paddy seedling by small scale farmers in the country. Hence, this is considered as an activity that needed mechanization. For mechanization the modeling and simulation evaluated for hand operated rice seeding machine, which is help the farmers to planting more and more amount of rice in good quality with low energy consumption and less harm to the environment. India is predominately an agricultural country with rice as one of its main food crop. It Produce about 80 million tons rice annually which is about 22% of the world rice production. Culturally transplanting of young seeding is preferred over direct seeding for better yield and better crop management practice. But this operation requires large amount of manpower (about 400 Man-Hour/ha) and task is very laborious involving working in stopping posture and moving in muddy field.

SRI is an approach to growing rice that can double or increase yields compared to conventional methods. It involves transplanting young seedlings in a wide, square spacing and maintaining moist soil conditions instead of flooding. This allows the plants to develop large root systems and produce many more tillers with more grains. Trials in Madagascar and Bangladesh found SRI methods increased yields compared to conventional practices. Further evaluation is needed to assess its sustainability and productivity under Bangladesh conditions, but it offers potential to increase yields with lower water, seed, and fertilizer requirements.
This document discusses heterosis breeding in rice and wheat. It provides an introduction to hybrid rice technology in India, including the history and development of hybrid rice varieties. Key points covered include:
- Rice is a staple crop for over 70% of the Indian population. Hybrid rice was first developed in China in the 1970s and introduced to India in the late 1980s.
- Different hybrid rice production systems are described, including cytoplasmic male sterility (CMS) systems like three-line hybrids, and genic male sterility systems like photoperiod sensitive genic male sterility.
- Over 70 hybrid rice varieties have been released in India so far by public and private institutions. Popular hybrids

Willem A. Stoop presents on ecological intensification lessons learned from the System of Rice Intensification (SRI). He discusses two approaches to intensification - conventional using modern varieties, dense planting, irrigation, and chemicals, and ecological using local varieties, low seeding rates, and organic inputs. SRI is presented as an example of an agro-ecological approach using practices like young seedlings, wide spacing, and alternate wetting and drying of soils. SRI results in increased growth, yields, and resilience through enhanced root and soil biology. However, SRI challenges conventional agricultural sciences' focus on increasing planting densities and fertilizer use over soil health and plant spacing.

1. African farmers today are more educated, connected, market-oriented, and aware of issues like climate change than previous generations. They are also more open to new ideas and collective action approaches.
2. Efforts to improve agriculture must consider rural-to-urban migration trends in Africa. While migration is driven by rural challenges, the younger generation remaining in rural areas is more educated and eager for progressive agriculture.
3. Things that should be avoided include mechanization tied to large-scale capital-intensive operations, land grabs, and agricultural models that turn farmers into laborers with no opportunity for management roles. Monoculture and large-scale foreign-owned farming should also be avoided.

1. Mechanization and the
System of Rice Intensification (SRI)
Because SRI changes the distance between plants, the number of seeds/seedlings per hole and the age of seedlings, new
planting equipment needs to be invented or old equipment adapted. In order to reduce the drudgery of hand-weeding, manual
and mechanized weeders have been devised, from one row to multiple row weeders. There is much room to improve upon the
existing designs, according to edaphic conditions and gender preferences. To scale up SRI, efficient and solid equipment needs
to developed and become available at farmers’ levels in Africa, Asia and Latin America.
Hand pushed

SRI weeders come in a variety of sizes, shapes and style, reflecting the need for local adaptation to
soil and climate conditions and gender preferences:

Motorized
weeders
As SRI spreads, weeders have increased in complexity and efficacy, allowing farmers to maximize
productivity gains from SRI.
Mechanical weeders range from
simple 1-2 row push machines
(above), to simple rotary weeders with a small engine, to more
complex and manufactured
multi-row weeders attached to
lightweight tractors.

Direct
seeders and
transplanters
Mechanization of SRI plantings requires development of new transplanting or direct seeding implements.
Below is some equipment that is in various stages of being adapted to SRI conditions.
Drum seeder
A conventional rice transplanter in Iraq transplants
several seedlings/hole. Adjusting the machine to transplant a single seedling is a challenge. These machines
are also delicate and expensive, and thus not appropriate for many smallholder-farming environments in the
tropics. We believe that vegetable transplanters might
be easier to adapt to the SRI system, and also cheaper
and more robust than the current rice transplanters.
The example from Pakistan is a good inspiration (photos on the right).

In many upland conditions, direct
seeding is more appropriate than
transplanting. This drum seeder
spaces rows evenly, but number
of seeds per pocket and distance
between plants within the line is
not optimally controlled.
