Here's a brief write-up about BharatRohan.
What is BharatRohan?
BharatRohan is involved in empowering farmers by reducing losses through prediction of pest attacks and disease outbreaks in the crops. We are a team of aeronautical engineers and hyperspectral imaging experts implementing affordable UAVs/Drone, Hyperspectral Imaging, data analytics and machine learning technologies to meet local farm challenges.
How does it work?
Our technology is based on Hyperspectral Imaging which determines minuscule colour changes occurring in the plants due to physiological and phenological changes. For example: When a disease like bacterial blight infects a pomegranate plant, it is caused by a pathogen called Xanthomonas axonopodis pv. punicae. This pathogen releases a number of effector proteins including TAL effectors into the plant through their secretion system. This effector protein causes some biochemical change in the plants and leaves. With human eyes, these changes become visible only when the water absorbing red-brown spots become visible on leaves. But with Hyperspectral imaging, we are able to identify the colour changes occurring in the leaves due to these biochemical changes - even at just the onset of the infestation which helps us in providing early predictions and forecasts to the growers so that losses can be prevented.
We diagnose the problems of the farmer field with a non-destructive method of Hyperspectral Imaging and create prescription maps. These prescription maps are then converted into recommendations reports in vernacular language of the farmers. The recommendations are duly validated by the agronomists/pathologist/entomologists whom BharatRohan has access to being a portfolio company of a-IDEA, TBI of ICAR-National Academy of Agriculture Research Management, Hyderabad. We have very strong partnerships with them through a-IDEA, technology business incubator of ICAR-National Academy of Agriculture Research Management, Hyderabad.
Presently BharatRohan is working on Mentha cropping system which is a very significant revenue source for the farmers in Uttar Pradesh where 90% of India's Mentha is cultivated and exported. The cropping system involves Mentha, paddy, mustard and potato crop. BharatRohan is building spectral libraries in association with CSIR-Central institute of Medicinal and Aromatic Plants, Lucknow. CSIR-CIMAP handles the microscopic inoculation of pathogens in controlled conditions. The phenological/biochemical changes are then used to generate a comprehensive spectral library which are then correlated with and applied on Drone/UAV based Hyperspectral Data acquired from farmers field using various proprietary unmixing models.
The major objectives of this project are:
-Provide unprecedented advisory services through a proprietary ICT Platform to around 5000 acres of area in 6 tehsils of Barabanki District
-Diagnose mineral deficiencies (NPK, Zinc and Iron) in Mentha Cropping System and suggest control methods.
-Diagnose pest attacks, disease outbreaks in Mentha cropping system and suggest control methods.
-Characterise weed infestations and suggest control methods.
-Reduce irrigation frequency.
-Promote use of sustainable precision agriculture
Past experiences include:
-Diagnosis of NPK deficiency in Sugarcane Crop in Baramati, Maharashtra
-Diagnosis of Weed grub pest in Sugarcane crop in Baramati, Maharashtra
-Diagnosis of Nitrogen deficiency in Pomegranate orchard in Kasindra, Rajasthan
-Monitoring morphological and phenological changes in Kasindra, Rajasthan
