  • Introduction

    Rice is the most important food crop of our country. More than 50% of our country population consume rice as their staple food. However, in recent years, rice cultivation is facing many sustainability problems including degrading natural resources, environmental pollution, change in pest and disease incidence, increasing production cost and lower return. Most of these problems are due to practice of non-scientific method of rice cultivation for many decades. Many technologies were developed to overcome this sustainability related problem associated with rice cultivation.

    Even after development of many improved technologies and cultivars, the problems are not solved in the farmer’s field. This is due to poor knowledge transfer and complexity of the new technology. To overcome this problem in agriculture, recently many android-based apps are being developed. Use of these applications help in solving complex decision-making process into simpler one. Similarly, spreading agricultural related information to the farmers was made easier with the help of mobile apps. Timely dissemination of precise information is critical to minimise wastage and therefore increased in efficiency. Optimizing the use of fertilizer, seeds and water can also be done by utilizing mobile and cloud computing technologies. This helps farmers save money while reducing consumption. The benefits of such connectivity and information flow is that it helps farmers make better crop and land management decisions. These applications also reduce the transaction cost of information.  Many apps have given new direction and approach to farmers to communicate directly and share their problems with government officials, extension workers, and subject matter specialist.

    The feedback of users suggested that use of mobile and cloud-based applications not only addresses the sustainability challenges but also add financial benefits for both large agriculture-based companies and farmers. Short  message  service  (SMS)  and  voice  record  have  given  improvements  in  social  relations between farmers and scientist. The knowledge and inform about choice of appropriate variety, fertilizers, pesticides and other agricultural inputs are made available to rural farmers at their doorstep. Use of android based app has the potential to make agriculture more productive, more consistent and to use time and resources more efficiently. This brings critical advantages for farmers and wider social benefits around the world.

    This article provides the complete information about the various android based applications available in google play store for rice crop management. Here, the android based apps for rice is divided in five major categories.

    1. Apps for nutrient management

    2. Apps for pest and disease management

    3. Apps for water management

    4. Apps for rice cultivars information and its demand estimation

    5. Apps for rice crop management

    Farmers can freely download and use these application. Many state government in India providing smart phones to farmers in order to enhance the farmers, scientist communication better and easier. Young generation farmers showing higher interest and adoption of smart farming practices. However, bringing all the new technologies under single umbrella is very important. Thus, this article provides the complete information of all the smart application available for rice crop cultivation.

  • Apps for Nutrient Management

    2.1. RiceNxpert

    Under the RESILIENCE project, the ICAR-National Rice Research Institute created a smart nitrogen (N) monitoring and guidance application in partnership with the Norwegian Institute of Bioeconomy Research. Nitrogen is a critical major nutrient element for rice cultivation. During the growing season, N fertilizers are applied in split doses at important growth periods to meet its N requirements. However, the N application often not matching with rice crop N requirement. This is due to lack of knowledge about rice crop N requirement by farmer. A smart android-based application for leaf colour monitoring and N rates suitable for different rice ecologies was developed to monitor and determine the leaf N content and record real-time N fertiliser requirements in order to coordinate the demand and supply. The RiceNxpert is a web and android application that analyses rice leaf colour and recommends N fertiliser doses to synchronise plant demand and supply of N. This will aid farmers in determining the best time and dose of N to apply to rice plants. This is an easy-to-use tool that makes direct recommendation in terms of urea/hectare after analysis of the rice leaf colour (https://play.google.com/store/apps/details?id=cocypher.com.lccapp&hl=en_IN&gl=US).

    2.2. Nutrient Decision Support Systems (NuDSS) for Irrigated Rice

    NuDSS is a general decision support system for irrigated rice in tropical and sub-tropical Asia that captures the most relevant cropping circumstances. For irrigated rice, the NuDSS provides decision aid on SSNM. The NuDSS software programme aids in the creation of new fertiliser strategies that result in more efficient fertiliser use, higher and longer-lasting yields, and higher profits for farmers. The software was created in response to a need for decision aids that could help with sophisticated mathematical computations that would otherwise be impossible to accomplish. All current high-yielding rice varieties with a harvest index of around 0.50 follow the same plant feeding principles. A general settings menu specifies crop and site-specific conditions as well as instructions for local adaptation when conditions deviate from the norm (https://www.ipipotash.org/publications/eifc-75).

  • Apps for Pest and Disease Management

The knowledge base includes general decision rules that represent pest and disease experts’ knowledge. It comprises 90 insect pest identification rules and 105 disease identification rules. An interface was created that included a questionnaire, popup menus, and list boxes with photos for each item in the drop down menus. In order to undertake formalised reasoning for user replies and matching rules in the knowledge-base, an inference mechanism was constructed using ASP.Net. Control measures such as biological, cultural, chemical, and resistant types were given their own module. These controls are suggested based on the crop stage, insect kind, nature and extent of damage, and economic threshold level. The user interface is entirely menu-driven, with combo boxes, option groups for picking responses to multiple-choice questions, and most of the questions supplemented by graphics for user convenience. Progressive farmers and agricultural extension officials can use this approach to speed up the decision-making process (http://www.ricexpert.in/).
