I) Indo-Russian project (DST-RFBR)
(Department of Science & Technology - Russian Foundation for Basic Research)
Summary of Progress
A) Ground survey
GPS handheld device was used for considering sugarcane homogenous plots at different phonological stage during the 2019 season. The ground data have been uploaded to VEGA-GEOGLAM to validate by time-series NDVI composite images.
The spectral and temporal profiles of the sugarcane crop were analyzed which helped us in separability of sugarcane with other crops.
750+ samples of sugarcane and other major crops (maize, wheat and turmeric) were surveyed for analyzing crop separability (crop classification) with different agronomic parameters e.g. crop type, crop variety, date of plantation, date of harvesting, intercropping, mix cropping, soil type, irrigation type, and yield.
These samples were considered randomly between Bagalkot and Belgaum district.
B) Arable land mapping
The sentinel-2 images were considered for extracting the arable lands.
The images were broadly classified into 5 classes namely agriculture, forestry, waterbody, built-up and fallowland.
The maximum likelihood classifier was adopted to classify the study area.
C) Crop classification and variety identification:
We are applying different machine learning algorithms like support vector machine and neural using ENVI software. We are yet to receive outstanding results from any of the algorithms.
Further other machine learning methods like Random Forest (RF) will be used if accuracy needs to be enhanced.
Variety: Main sugarcane growing varieties in Bagalkot and Belgaum like Co 86032, Co 0671 and Co 91010 are being analyzed based on their spectral changes at different phonological stages for separability.

II. KIAAR is now a JECAM Centre
We are now one of the only two JECAM (Joint Experiment of crop Assessment and Monitoring) Centres from India. The other one being Vijayawada registered by IIT, Mumbai. JECAM is an initiative of GEO (Group on Earth Observations).
The advantages of being a JECAM centre
Free SAR images of RADARSAT – 2 Satellite, (two each month) which otherwise would cost around $ 3000 per image.
These images help us in crop monitoring even during cloudy days in monsoon season.
The JECAM initiative is focused on developing and comparing methods, establishing data collection and reporting standards and developing best practices, through the analysis of coordinated ground and satellite data collected for a number of well documented sites around the World.
The JECAM sites are looking at a common range of monitoring needs over a very diverse range of landscape conditions and cropping systems, including:
Crop identification and acreage estimation
Near Real Time crop condition

Work done and Activities
From April-2018 to March-2019 about 2339 soil samples and 29 water samples were analysed.
Vermicompost production capacity was doubled by constructing additional Vermi compost pits. With this expansion, KIAAR is now able to produce around 100 tons of Vermicompost per annum which is being used on KIAAR farms.
Biofertilizer production has been started. License for the manufacture and sale was obtained from the Government of Karnataka. So far, two tones of Biofertilizers (N fixers – Azospirillum brasilense, Gluconacetobactor diazotrophicus and P solubilizer – Bacillus megaterium) have been supplied to Solar Magic Private Limited for sale to farmers.
The current production capacity is 30 tones/annum. It is proposed to upscale the production facility to 200 tones/annum. As per the suggestion of CMD, an application for a term loan of Rs.1.50 crores has been submitted to the Union Bank of India. The Bank Officers have inspected the existing facilities and have submitted the report to the sanctioning authority.
About 42,000 Tissue Culture plantlets and 12, 45,327 single eye bud settlings were produced from April – 2018 to March – 2019.
