IFPRI - 00916 - Zero Tillage in the Rice-Wheat Systems of the Indo-Gangetic P…CSISA
This document reviews the success of zero-tillage wheat farming in the rice-wheat systems of the Indo-Gangetic Plains. The adoption of zero-tillage technology has increased in the last decade, with 1.76 million hectares and 620,000 farmers using it in India by 2008. Zero-tillage allows wheat to be planted directly into unplowed fields, significantly reducing tillage and production costs. Farmers adopting zero-tillage can increase income by around $100 per hectare. While primarily providing economic benefits so far, zero-tillage may also provide environmental benefits if adopted for rice crops and combined with other conservation agriculture practices. Further research is still needed to fully understand its social
Soil moisture, nutrients, and weeds in no tilluiolgawalsh
This document discusses the benefits of no-till farming for soil moisture, nutrients, and weed control. It begins with an overview of the history of tillage and the dust bowl era that drove adoption of conservation tillage. No-till farming maintains soil moisture by leaving crop residue to reduce evaporation and erosion. It also builds soil organic matter and nutrients over time by keeping roots and residues in the soil. While no-till increases dependence on herbicides for weed control, precision weeders can reduce herbicide usage. Overall, no-till can help ensure more sustainable agricultural systems.
Zero tillage, also known as no-tillage, involves direct seeding of crops into untilled soil with minimal soil disturbance. It provides benefits such as conserving soil moisture, reducing erosion, and allowing timely sowing of crops. However, it also poses some challenges like increased soil compaction and potentially lower yields for some crops compared to conventional tillage. Overall, zero tillage is seen as an important conservation agriculture practice for improving the sustainability of cropping systems.
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.
About the necessity of adequately defining no-tillage - a discusssion paper. ...Joanna Hicks
The document discusses the need for a precise, science-based definition of no-tillage farming to ensure consistent and comparable research results. Currently, there is no agreed-upon definition, and researchers use different definitions and practices leading to contradictory findings. The author argues that no-tillage should be defined as a holistic system that retains crop residues as mulch, uses low-disturbance seeding equipment, and incorporates integrated pest management without tilling over 50% of the soil surface. A detailed description of the system and research methods is needed for meaningful comparison of no-tillage research results.
The document summarizes the System of Rice Intensification (SRI) method of rice cultivation. SRI uses younger seedlings, wider spacing between plants, less flooding of fields, and other practices. It can significantly increase rice yields, often doubling average yields, while reducing water, seed, and other input needs. SRI goes against conventional agriculture wisdom but evidence shows it improves root and tiller growth, leading to higher productivity from existing rice varieties and genomes.
System of rice intensification status, issues and future research strategiesAshutosh Pal
System of Rice Intensification (SRI) is a methodology for increasing rice yields through changes in management practices such as transplanting younger seedlings in a wide spacing, reducing plant populations, incorporating organic materials, and modifying water management through intermittent irrigation. Studies at the Central Rice Research Institute in Cuttack, India found SRI methods increased yields by 21-24% compared to local recommended practices, through improvements in number of tillers, panicle length, and spikelet fertility. SRI also used fewer seeds, less water, and less chemical inputs but produced higher yields through improved root growth and plant vigor. Further research focused on optimizing variables like seedling age, crop density, and water regimes to maximize the benefits
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.

The document discusses different conservation tillage systems such as ridge tillage and no-till. Ridge tillage uses specialized planters and cultivators to maintain permanent ridges for row crops, while no-till does not use tillage and simply plants crops into previous crop residues. No-till provides soil erosion control and requires fewer field passes but may have issues with weeds, pests, and slower soil warming. The document also describes an innovative no-till system developed by Steve Groff that uses cover crops and a roller to prepare fields with little herbicide.

This publication provides guidance on organic potato production practices including fertility and nutrient management, pest management, harvesting, storage, and marketing. It discusses using organic matter and crop rotations to build soil fertility as well as controlling insects, diseases, weeds, and nematodes without synthetic chemicals. Storage and economic issues are also covered. The goal is to grow healthy potato plants from certified organic seed using sustainable methods. Successful organic potato farming requires experimenting with different practices and marketing potatoes through various direct or wholesale channels.
1. The System of Rice Intensification (SRI) is a resource-saving, high-yielding rice farming method that can meet the needs of increased land and water productivity, accessibility for poor farmers, environmental friendliness, pest and drought resistance, and profitability for farmers.
2. SRI practices such as young seedlings, wider spacing, and intermittent flooding have been shown to increase yields by 50-100% with 25-50% less water and 10-20% lower costs of production compared to conventional methods across multiple countries.
3. SRI also provides benefits like reduced methane emissions, greater pest and disease resistance, stronger resistance to stresses like lodging and drought, and improved grain quality.
Conservation agriculture practices can help address problems with conventional agriculture in India like erratic rainfall, soil degradation, and high resource use. Minimum soil disturbance, permanent organic soil cover, and diversified crop rotations are the key principles of conservation agriculture. Adopting no-tillage and mulch farming can reduce runoff and evaporation, improve soil health, and increase water storage in the soil. Studies show conservation agriculture practices lead to higher yields and water use efficiency compared to conventional tillage and help promote a more sustainable agricultural system in India.

This document discusses resource conserving technologies (RCTs) and conservation agriculture (CA) practices for improving resource use efficiency in agriculture. It provides an overview of challenges facing agriculture such as increasing population pressure, rising costs, and resource degradation. It then summarizes global and Indian rice production systems and scenarios. Conservation agriculture practices like minimum soil disturbance, residue retention, and crop rotation are presented as ways to sustainably intensify agriculture and efficiently manage resources. Specific CA techniques for rice-wheat systems are also outlined, such as laser land leveling, zero-tillage, and raised bed planting.
Weed management in vegetable crops is important to achieve good economic returns. The problems of weeds in vegetable crops are more serious than in field crops due to the higher nutrient and water requirements of vegetables. Initial vegetable crop growth is also very slow. Several weed management practices can be used in vegetables including good crop husbandry, mechanical weed control, herbicides, soil solarization, and biological control. Data from studies show that different weed management treatments significantly impact weed population, plant growth, and crop yield. Integrated weed management approaches that combine cultural, mechanical, and chemical control methods provide effective weed control in vegetable crops.

This document discusses cassava agronomy research being conducted by IITA. It notes that cassava yields in Africa are typically much lower than potential yields, due to factors like soil degradation, lack of suitable fertilizer recommendations, and insufficient knowledge of crop responses. IITA is working on projects like the African Cassava Agronomy Initiative to develop improved agronomic practices. On-farm trials are focusing on optimizing fertilizer use, weed management, and intercropping practices to increase cassava productivity for smallholder farmers in Africa. The results will provide site-specific recommendations to boost yields and food security.

- The document discusses experiences with the System of Rice Intensification (SRI) in Uttarakhand and Himachal Pradesh in India, which have seen food deficits. SRI practices including young seedlings, wider spacing, single seedlings, and organic matter addition have led to increased rice yields.
- SRI principles were adapted for other crops like wheat, finger millet, and kidney beans. Trials showed yield increases of over 60% on average compared to conventional practices. SRI was expanded to cover over 13,000 farmers and 551 hectares during drought conditions in 2009.
Effects of crop establishment methods and irrigation schedules on productivit...fatehsekhon
Rice is the staple food for more than half of the global population. In India, it is grown on an area of about 43.97 m ha with total production and productivity of about 104.32 mt and 2.37 t/ha respectively (Anonymous 2013). In Punjab, it occupied an area of 2.82 m ha with production and productivity of 10.54 mt and 3.74 t/ha respectively and in Haryana, it was grown on an area of 1.24 m ha with production and productivity of 3.76 mt and 3.02 t/ha respectively (Anonymous 2013).
The most common practice for establishing rice in rice wheat system of indo-gangatic plains region is puddling before transplanting. Alternative to traditional method direct seeding may be adopted because it does not require that heavy amount of labour, water and capital input initially and also crop mature earlier (7-10 days) than transplanted crop allowing timely sowing of succeeding wheat crop. Recent research suggests that new methods of rice establishment, viz zero till rice, bed planting and SRI has potential to reduce cost and increase sustainability of irrigated rice culture while maintaining yield.
Irrigation plays a pivotal role in increasing productivity of rice. The efficiency and productivity of irrigation water is quite low owing to percolation losses and high water requirement. There is an urgent need to save water and increase its efficiency in rice production. Various agronomic practice like proper land levelling, proper transplanting time, selection of suitable variety and increasing interval between successive irrigation can play a lead role in water saving and to obtain sustainable yield of the crop. The sustainability of rice production in north-west India is threatened by scarcity of water. So there is need to increase water use efficiency in rice production.
Gangwar and Singh (2010) resulted that among different crop establishment methods, highest yield and yield attributing characters of rice was obtained with drum seeding wet bed method. Gill et al (2006) revealed that dry matter accumulation, leaf area index, effective tillers and grain yield were significantly more in direct seeding than transplanted rice. Water productivity in direct seeded rice was higher as compared to transplanted rice clearly showing the more water use efficiency in DSR. Jagtap et al (2013) concluded that the crop established by transplanting recorded significantly higher growth as well as yield attributes resulting in to significantly more grain and straw yield. Grain yield found to be highest in Japanese manual transplanted rice followed by dry drilling (30 kg/ha), dry drilling (15 kg/ha) and drum seeding (Dixit et al 2010). Singh et al (2005) found that mechanical transplanting of rice resulted in highest grain and straw yield which was at par with manual transplanting but significantly higher than both direct seeding methods.
Agronomic approaches for managing drought stress include:
1. Choosing drought tolerant crop varieties that escape drought conditions through early flowering.
2. Adjusting planting dates to avoid drought periods. Delaying sowing dates can reduce yield.
3. Optimizing sowing depths from 4-8 cm depending on the crop to maximize yields.
4. Seed priming treatments like water soaking or salt solutions can improve seed germination and establishment.
The document discusses the System of Rice Intensification (SRI), an agricultural method that indicates a path toward post-modern agriculture. SRI was developed in Madagascar in the 1980s and aims to produce more rice with less water and other inputs through changes in plant, soil, and water management rather than external inputs. The document summarizes evidence that SRI leads to higher yields, less water use, lower costs, and greater resilience compared to conventional rice production methods. SRI practices have now spread to over 38 countries across Asia, Africa, and Latin America.

Presented at: The International Conference on The System of Crop Intensification (ICSCI22)
Date: December 12, 2022
This document summarizes research on using System of Rice Intensification (SRI) methods in Iraq to increase water savings and rice yields. The research found that using SRI with 3-day or 7-day intervals between irrigation used 50% and 72% less water than continuous submergence, and increased yields by 20% and 11% respectively. SRI with 3-day intervals also had the highest water productivity and net economic return, making it a promising strategy for Iraq's water-deficit conditions. The document recommends wider adoption of SRI through incentives, mechanization support, and collaboration with water user associations.

Title: Sistema Intensivo del Cultivo del Arroz para la Producción y Sustentabilidad del Rubro
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.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
