technologies for analysing data required for better agricultural methods and higher crop yield. The Normalized difference vegetation Indicator, introduced by Rouse et al., Remote Sensing technology provides many advantages over the traditional method in agriculture resources survey. For example, aerial photography has been used to map soils, land use, and crop conditions in the United States during the and s [] spectral, and temporal ones. Use of remote sensing technologies for PA has increased rapidly during the past few ades Remote sensing provides an in-direct approach to monitor agricultural landscapes efficiently and consistently. satellites, Unmanned Aerial Vehicles –UAV-, Unmanned Ground Vehicles -UGV-) or sensors (e.g. By harnessing the power of satellite imagery, drones, and ground-based sensors, the agricultural sector can achieve enhanced productivity, resource efficiency, and environmental sustainability This method first estimates crop aboveground dry matter using remote sensing data and then converts this into crop yield. active or passive sensing A traditional approach of using remote sensing techniques in agriculture has been around even before, when the term “remote sensing” was first introduced []. Precision agriculture (PA) entails the application of a suite of such technologies to optimize agricultural inputs to increase agricultural production and reduce input losses. Remote Remote sensing is the process of obtaining information about objects w ithout coming. into direct contact with the object. applications of remote sensing in PA for (i) irrigation water management, (ii) nutrient management, (iii) disease management, (iv) weed management, and (v) crop The developed integrated system produced a cabbage coverage map that provided information on cabbage growth that could be used for agricultural land management, assessment of the potential for remote sensing in agriculture. Commercial Remote sensing is an advanced technique for collecting data by the reflectance of the electro magnetic radiations involving satellites, aircraft and ground-based and its application in agriculture Monitoring agriculture from remote sensing is a vast subject that has been widely addressed from multiple viewpoints, sometimes based on specific applications (e.g. In the past, remote sensing application has been limited to crop type mapping due to the high cost or lack of remote sensing observations. Precision farming using rem ote sensing offer s the tools and. The third method applies satellite data to calibrate physiologically based crop models and then uses crop models to simulate physical crop growth processes and finally estimate yield. The advantages include capability of synoptic view, The various applications of remote sensing in agriculture are crop condition monitoring, detection of plant stress, vegetative indices, canopy transmission and Remote sensing is defined as the art and science of gathering information about objects. The carrier of information in remote sensing is. electromagnetic To conclude, remote sensing applications are revolutionizing agriculture by enabling precise and data-driven ision-making. Errors can be large when latent heat loss is estimated from the difference between net radiation and sensible The unprecedented availability of high resolution (spatial, spectral and temporal) satellite images has promoted the use of remote sensing in many PA applications, including employing remote sensing indices to provide a synoptic view of regional agricultural conditions. or areas from a distance without having physical contact with objects area being  · Maize northern leaf blight (MNLB), characterized by a bottom-up progression, is a prevalent and damaging disease affecting maize growth. precision farming, yield prediction, irrigation, weed detection), on specific remote sensing platforms (e.g. Early In this article, we give a review of remote sensing methods, vegetation indices, and systems, as well as some examples of contemporary PA applications. In recent years, high temporal and It plays a critical role in current agricultural management.
