Automated Agro Advisory Service - (TNAU AAS)

Success of monsoon based agriculture depends on the climate that prevailed during the particular cropping season.Providing real time weather information based agro advisory to the farmers could minimize the risk and losses due to extreme climate

In order to improve the accuracy of present weather forecasting, weather information are required at high spatial and temporal resolution. Installation and interlinking of automatic weather stations (AWS) at block level will be helpful to avoid climaterisks and increase the productivity by timely weather based agro advisory.

In this context, Government of Tamil Nadu under National Agricultural Development Project (NADP) has funded Rs. 29.83 crores for establishing Tamil Nadu Agriculture Weather Network (TAWN) by installing 385 AWS, each one per block. During 2007-10, in the first phase 224 AWS were installed with a total outlay of Rs. 16.90 crores and 161 AWS were installed in the second phase during 2011 -16.

Agro Climate Research Centre (ACRC), Directorate of Crop Management, Tamil Nadu Agricultural University (TNAU), Coimbatore in collaboration with Department of Agriculture, Tamil Nadu established the Tamil Nadu Agriculture Weather Network (TAWN). In this network, 10 types of agricultural related weather parameters viz., maximum temperature, minimum temperature, rainfall, relative humidity, wind speed, wind direction, soil moisture, soil temperature, leaf wetness, sunshine hours, solar radiation are collected from 385 AWS at hourly interval and hosted in this public domain www.tawn.tnau.ac.in. The daily, weekly and monthly weather data are also calculated and hosted in this website at block level. The medium range weather forecast at block level is being generated by using these weather parameters is also hosted every day with a lead time of six days.

Response farming is a farming method with advisories received from the technocrats based on local weather information and crop weather simulation models. Success of response farming viz., increased productivity and reduced risk has been already recorded in Tamil Nadu by TNAU and many other states. The main reason for the success of response farming lies with location and time specific technologies. It is the right time to carry forward the success of response farming to entire farming community. In continuation of Tamil Nadu Agricultural Weather Network (TAWN), TNAU scientists have stepped ahead to provide weather based “Automated Agro Advisory Service (AAS)”, directly to the farmers mobile.

In this context, Government of Tamil Nadu under National Agricultural Development Project (NADP) has funded Rs. 3.50 crores to Agro Climate Research Centre, Directorate of Crop Management, Tamil Nadu Agricultural University, Coimbatore for developing a software to send weather based agro advisory SMS to farmers. The scientists of ACRC have successfully achieved the robust task by developing 54 weather windows involving past, present and future weather, agro advisory for the developed weather window to each five growth stages of 108 crops. Using the above details, weather based agro advisory will be generated individually to registered farmer’s own crop through the special “AAS software” and disseminated as SMS in local language. This software is the first in India to automate the weather based agro advisory. The farmers can freely register their mobile number in this portal, choose their crop and sowing time.

With the increasing demand on accurate weather information and weather based agro advisory, TNAU’s Tamil Nadu Agriculture Weather Network(TAWN) and Automated Agro Advisory Service(AAs) stands in front to help the farmers to plan, implement and harvest the success in farming.

基于季风的农业的成功取决于特定种植季节期间的气候。向农民提供基于实时天气信息的农业咨询可以最大限度地减少极端气候造成的风险和损失

为了提高当前天气预报的准确性，需要在高空间和时间分辨率下的天气信息。在区块一级安装和连接自动气象站（AWS）将有助于避免气候变化，并通过及时的天气农业咨询提高生产率。

在这方面，国家农业发展项目（NADP）下的泰米尔纳德邦政府资助了卢比。通过安装385 AWS建立泰米尔纳德邦农业气象网络（TAWN）29.83亿卢比，每个区块每个。在2007-10期间，在第一阶段224安装了AWS，总支出为卢比。 2011年至2016年期间，第二阶段安装了16.90亿卢比和161个AWS。

农业气候研究中心（ACRC），泰米尔纳德邦农业大学作物管理局（TNAU），哥印拜陀与农业部合作，泰米尔纳德邦建立了泰米尔纳德邦农业气象网络（TAWN）。在该网络中，从385 AWS收集了10种与农业相关的天气参数，即最高温度，最低温度，降雨量，相对湿度，风速，风向，土壤湿度，土壤温度，叶片湿度，日照时数，太阳辐射。每小时一次并在此公共领域托管www.tawn.tnau.ac.in.每日，每周和每月天气数据也在本网站的块级计算和托管。通过使用这些天气参数生成块级别的中期天气预报，每天还提供六天的提前期。

响应农业是一种农业方法，根据当地天气信息和作物天气模拟模型从技术专家那里收到建议。 TNAU和许多其他州已经在泰米尔纳德邦记录了应对农业的成功，即提高了生产力和降低了风险。应对农业成功的主要原因在于地理位置和时间特定技术。现在正是将反应农业成功推向整个农业社区的最佳时机。继泰米尔纳德邦农业气象网络（TAWN）之后，TNAU科学家们已经开始直接向农民手机提供基于天气的“自动农业咨询服务（AAS）”。

在这方面，国家农业发展项目（NADP）下的泰米尔纳德邦政府资助了卢比。向农民气候研究中心，泰米尔纳德邦农业大学作物管理局，哥印拜陀开发软件，向农民发送基于天气的农业咨询短信。 ACRC的科学家通过开发涉及过去，现在和未来天气的54个天气窗口，以及针对108种作物的每五个生长阶段的发达天气窗口的农业咨询，成功地完成了这项强有力的任务。利用上述细节，将通过特殊的“AAS软件”为注册农民自己的作物单独生成基于天气的农业咨询，并以当地语言传播为SMS。该软件是印度第一个自动化天气农业咨询的软件。农民可以在这个门户网站上自由注册他们的手机号码，选择他们的作物和播种时间。

随着对准确天气信息和天气农业咨询的需求不断增加，TNAU的泰米尔纳德邦农业气象网络（TAWN）和自动农业咨询服务（AAs）站在前面，帮助农民规划，实施和收获农业的成功。
