1 Introduction to yield gap analysis

CIP-PSE

This document summarizes a workshop on potato yield gap analysis held in Kenya. It discusses the importance of analyzing yield gaps to meet increasing global food demand through closing yield gaps rather than expanding agricultural land. Potato production and yields are increasing in sub-Saharan Africa but remain low on average. The concepts of potential yield, attainable yield, and actual farmer yields are introduced. Yield gaps are defined as the difference between potential and actual yields and can be measured at local or broader scales. Methods for estimating potential and actual yields are described. An example from Rwanda shows a large yield gap between potential and actual potato yields.

RJRANJEET1

Dr. B. L. Sinha discusses the history and definition of precision agriculture. Precision agriculture has been practiced for hundreds of years through adaptations like the transition from horse-drawn plows to tractors. In recent decades, technology like GPS, GIS systems, and remote sensing has allowed for more precise data collection and analysis at subfield levels. This enables variable applications tailored to spatial and temporal variability in fields. By improving efficiency and reducing waste, precision agriculture benefits farmers through increased profits and more sustainable practices.

PRECISION FARMING

akashatute

Precision farming refers to the precise application of agricultural inputs based on soil conditions, weather, and crop needs to improve productivity, quality, and profits. It uses technologies like GPS, GIS, and remote sensing to more efficiently apply inputs and maximize crop yields without pollution. Precision farming allows farmers to do the right activities in the right locations at the right times. It provides benefits over traditional farming through more effective use of resources.

Precision Agriculture; Past, present and future

NetNexusBrasil

This document provides an overview of the history and future of precision agriculture. It discusses early efforts using soil testing and yield monitors in the 1990s. Current technologies like crop canopy sensors that measure biomass and chlorophyll are highlighted. The document also reviews ongoing work optimizing in-season nitrogen management. International collaboration between USDA-ARS and Embrapa Brazil on precision agriculture research is summarized.

Precision farming uses remote sensing and data analysis to optimize crop yields. It involves observing field variations in crops and soil properties to determine management needs. Precision farming can increase productivity while reducing environmental impacts through efficient use of land, water, and agrochemicals. However, challenges remain in implementing precision farming technologies in some countries due to lack of expertise, high costs, and poor infrastructure.

Precision Farming by Dr. Pooja Goswami

College of Agriculture, Balaghat

Precision farming aims to optimize crop yields through site-specific management. It involves assessing field variability through soil sampling and remote sensing, mapping this variability using GPS and GIS technologies, and then managing the field variably based on these maps. This may include variable rate application of seeds, fertilizers, pesticides, and irrigation. Key technologies used include GPS for positioning, GIS for mapping and analysis of spatial data, and remote sensing for non-contact assessment of field conditions.

Assessment of wheat yield gap in Central Asia

ExternalEvents

This document analyzes wheat yield gaps in Central Asia through case studies from Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan. It finds that irrigated wheat yields could be increased 1.5 times through optimal irrigation and nitrogen application. Rainfed wheat yields could increase 1.6 times through early sowing, supplementary irrigation, busy fallow periods, crop residue retention, water harvesting, and optimal nitrogen application. Closing yield gaps requires improved varieties, crop rotations, optimal sowing dates, leaching to control salinity, and applying nitrogen after rainfall.

Precision farming involves using new technologies and collected field information to optimize agricultural practices based on variability within fields. It aims to do the right thing, in the right place, at the right time. This tailors inputs like fertilizers and pesticides based on conditions and can improve crop yields while reducing costs and environmental impact. Precision farming uses tools like GPS, GIS, sensors and software to gather and analyze data on soil properties, climate and crop conditions to develop customized farm management plans. While promising, precision farming faces challenges in adoption related to costs, farm size and lack of expertise in developing countries.

Precision agriculture in relation to nutrient management by Dr. Tarik Mitran

Dr. Tarik Mitran

Precision agriculture techniques can help optimize nutrient management by accounting for spatial variability within fields. Soil sampling is done on a grid to produce fertility maps showing nutrient levels in different areas. GPS and GIS combine to map yield and collect data that identifies low-yielding zones. Remote sensing uses imagery to detect differences such as no-till fields. Yield monitors coupled with GPS measure harvest yields in various locations. Variable rate technology then applies nutrients precisely based on need. This precision nutrient management improves efficiency and protects the environment.

Anusha K R

Precision farming uses technology like GPS, GIS, remote sensing, and variable rate application to optimize crop production by accounting for spatial and temporal variability within fields. It involves accessing variability through soil sampling and mapping, then managing that variability using tools like variable rate technology, site-specific planting, and nutrient management. This contrasts with traditional farming which treats entire fields uniformly without consideration for variability. The goal of precision farming is to improve crop yields and quality while reducing costs, waste, and environmental impact.

This document discusses the strengths, opportunities, and weaknesses of CRTs (reporting tables) in Mexico's AFOLU (Agriculture, Forestry and Other Land Use) sector. For livestock, a strength is characterizing production systems, while an opportunity is defining criteria to standardize information. A weakness is the diversity and resources needed to obtain information across Mexico and other countries. For lands, a strength is coherence in inventories and monitoring, while the diversity of flora poses a future challenge. For non-CO2 emissions sources, a strength is traceability in agriculture, while an opportunity is defining criteria to characterize production systems for monitoring.

Precision agriculture refers to applying agricultural inputs precisely based on soil, weather, and crop needs to improve productivity, quality, and profitability. It uses technologies like remote sensing, GPS, and GIS to enable more efficient use of inputs like pesticides, fertilizers, tillage, and irrigation water, bringing higher yields and quality without pollution. While precision agriculture is still nascent in India, studies show it can increase yields 2-3 times through proper soil testing and fertilizer application. Some Indian states and companies are piloting precision agriculture approaches tailored to India's socioeconomic conditions to evaluate yield increases and cost reductions compared to conventional farming. Widespread adoption in India will require overcoming educational, economic, and infrastructure challenges.

This project aims to improve rice production on acid soils by identifying rice aluminum (Al) tolerance genes. Researchers found rice does not use the root tip Al exclusion mechanism seen in other cereals. Through linkage and genome-wide association analyses, they identified the ART1 transcription factor and Nrat1 Al transporter genes as contributing to Al tolerance. Near-isogenic lines were generated containing tolerant alleles of four QTL regions to use for breeding. Variation in Nrat1 was shown to result in tolerant and sensitive versions affecting Al uptake. The research provides markers, genes, and lines to improve rice Al tolerance.
