STATUS OF WHEAT & POTATO 2020-21: A CASE STUDY IN HOSHIARPUR & JALANDHAR, PUNJAB

 

In Rabi season 2020-21, FASAL SALAH team carry out a study of crops grown in Hoshiarpur and Jalandhar district of Punjab. Wheat is the major crop of Hoshiarpur and Jalandhar district followed by Potato. Idea was to look at the crop on ground as well as from satellite to see if size the crop and yields could be determined.

FASAL SALAH App, Our Crop monitoring technology is unique using bottoms up approach with crop monitoring at field level and correlating ground realities with real-time crop vegetation index monitored via spectral analysis of high-resolution satellite images for different fields and crops. This enables to track positive and negative dynamics of crop development much more realistically.

This way it is more realistic way of crop yield estimation before actual harvest. Our technology has been field tested and awarded by Govt. of India (Winner of Great Agriculture Challenge 2019).  

 

Satellite Image Processing and Vegetation Index-

The Terra Moderate Resolution Imaging Spectroradiometer (MODIS) Vegetation Indices MOD13Q1 Version 6 (16-day composite) NDVI image product with spatial resolution of 250m, was used in this work. The satellite image has been pre-processed to rectify the geometrical errors.

The Soil Moisture Active Passive (SMAP) with 9 km resolution data used in this assessment, The SMAP spacecraft carries two instruments, a radar (active) and a radiometer (passive), that together make global measurements of land surface soil moisture and freeze/thaw state. It is useful for monitoring and predicting natural hazards such as floods and droughts, understanding the linkages between Earth’s water, energy and carbon cycles, and reducing uncertainties in predicting weather and climate.

During the rabi season sentinel- 2 (Optical) data was used for the crop classification. Sentinel-2 is the high-resolution optical satellite of ESA and the EU. The images have a resolution of 10 to 20 meters, higher than Landsat, and, as always with the Copernicus programme, the data are free and open. A single date Sentinel-2 imagery has been taken and individual bands of 10m spatial resolution NIR, R, and G are stacked together to create a multispectral image cube. Once the stacked image is generated subset the area on the basis of AOI (area of interest), then classified the stacked image using supervised classification and estimate the crop acreage of wheat crop during the rabi season.

Our main task is to conveniently combine all of the information about your fields in one place, to identify and draw the attention of farmers to problem areas. To achieve this, we collect data from different sources - satellite images, weather data, soil types, vegetation maps, among others - and supplement it with our own developments. After having analyzed the data obtained, the system notifies the user of possible risks and changes provides the ability to cluster fields and treat them accordingly, as well as predict yields. In the long run, the system allows for optimal resource utilization and effective decision-making.

Area of wheat crop in current year showing slightly lower from 144000 and 170000 ha of 2018-19 by 11% and 13 % respectively. On the basis of NDVI crop health condition of Hoshiarpur and Jalandhar district depicts normal condition with respect to the year 2018-19 in rabi season 2020-21 and same scenario can be seen in acreage estimation.
  • Average crop yield in Hoshiarpur and Jalandhar district for wheat and potato is approx. 55, 60 and 100, 93.5 quintals per hectare respectively. The crop is calculated when the farmers gives their inputs during the crop registrations in FASAL SALAH App i.e. date of sowing, soil, variety and our crop modeler met-GIS runs in the backend and monitor the crop at every stages throughout the crop cycle and predicts the crop yield before harvesting.

Technology - Advising Farmers and Crop Yield Assesment

Food security in the light of climate change is a global imperative. In developing nations, the problem is exacerbated by variable weather, lack of reliable extension services to optimize yield and fair market access. In India, most farmers do not have access to weather advisory forecasts that are hyper local to their field and timely in nature. As all farming activities are heavily dependent on weather, decisions on application of fertilizers and pesticide, irrigation, and even plucking of fruits & vegetables and harvesting cannot be taken efficiently. In addition, significant crop losses, that are entirely preventable, accrue through adverse weather events. Crop advisory services, where available, are generic and not pegged to a farmer's seed variety, date of sowing, and growing conditions and hence do not dispense timely, actionable advice, directly relevant to a farmer. Likewise, market trends pertinent to their particular crop and location

BKC Aggregators wins HDFC Digital Innovation Award

Good, better, best and never take rest until your good becomes better and better become best; it is the principle which is followed by Dr BK Singh, who is working tirelessly for the welfare of farming community across the country. After winning the Agriculture Grand Challenge (Govt. of India) 2018, BKC Aggregators has won HDFC's Digital Innovation Summit which was organized at IIM Ahmedabad, Gujarat on 31st January 2019.   FASAL SALAH provides timely and personalised agri- advisory for the welfare of farmers, a perfect solution for several problems being faced by farmers. Using dynamic crop models and artificial intelligence analytics, BKC has been able to generate an algorithm for calculation of yields well before the harvest. Thus it is possible now to have an accurate estimate of the crop before it is harvested by the farmers. Forecasting the yield before harvest is going to become strong tool for several problems associated to the losses and difficulties being face

BKC Aggregators: How it all started

Aggregators: BKC Aggregators vision is to transform the socio-economic fabric of India by creating farmer-entrepreneurs. Our mission is to provide timely and actionable information to each farmer to increase production and incomes, and mitigate risks with real-time yield forecasts. It all began in 1971 when our Founder, Dr. B. K. Singh, a fresh Ph.D in Agriculture from the Indian Agriculture Research Institute entered the workforce of post-independence and recently Green Revolutionized India.  Starting out with agriculture commodity trading at the State Trading Corporation of India, he continued to grapple with the challenges of bringing extension to farmers and how much weather affected livelihoods and, lives of farmers in India.   His first company, BKC WeatherSys, established in 1989, was the first entity to bring 7 day weather forecasts to India, the first to provide weather forecasts to farmers through text messages, and the first to build an automated forecasting software, metGIS
