Field Precision Agriculture

Vineyard Imaging & Phenology AI Study

Commercial grape growers still make critical spray, thinning, and harvest calls by subjective eye. We pair consistent row-by-row smartphone camera surveys with manual physiological ground truth across Thompson Seedless vines at our private testbed in Sindagi taluk, Vijayapura district.

The Agronomic Challenge

High-value crops require objective spatial data

In table grapes and raisins, income swings dramatically based on bunch uniformity, disease outbreak timing, and the final fresh-to-raisin drying ratio.

GROWTH & SIZING

Canopy & Berry Uniformity

Did the growth regulator doses work evenly across vineyard rows? Conventional sampling checks 2-3 vines. Smartphone cart video surveys can record every vine canopy on both sides.

DISEASE LOCALIZATION

Early Downy & Powdery Mildew

Mildew spreads invisibly until whole sectors are damaged. High-resolution camera imagery flags subtle leaf spotting and sporulation before farm-wide canopy collapse.

RIPENING DYNAMICS

Brix Curve & Raisin Grade

Sugar develops unevenly within a vineyard block. Linking individual row imagery with refractometer Brix and raisin recovery percentages optimizes selective harvest timing.

Four-Phase Field Study Protocol

A structured, multi-season scientific campaign conducted at our Thompson Seedless vineyard in Sindagi taluk, Vijayapura district.

PHASE 01 · OCTOBER TO DECEMBER

Bud Break, Shoot Architecture & Berry Sizing

Reference vines tagged across the plot. A lightweight push cart equipped with mounted smartphone cameras traverses rows weekly, capturing vines from both canopy flanks alongside manual vernier caliper measurements.

PHASE 02 · JANUARY TO MARCH

Veraison (Colour Change) & Sugar Accumulation

Survey frequency increases to 2 passes per week. Hand refractometer Brix measurements taken on marked bunches across micro-zones, tracking sugar accumulation curves against visual bunch color.

PHASE 03 · HARVEST & YIELD CORRELATION

Row-by-Row Harvest & Fresh Weight Logging

Total harvested fruit weighed per row to evaluate early-season canopy coverage and bunch count estimates directly against final row biomass.

PHASE 04 · CURING & DRYING

Drying Yard Recovery & Raisin Grading

Bunches tracked through the drying shed to log fresh-to-raisin conversion ratios and grade final color and size against in-season vision data.

Academic Partnerships

Student Fellowship & Faculty Collaboration

We recruit 2nd and 3rd year horticulture and engineering students, providing hands-on AI field research experience, bus transit coverage, and formal credit.

For Students

  • • Role: Operate the smartphone imaging cart, record physiological measurements on tagged vines, maintain structured field logs.
  • • Time Commitment: Weekly visits Oct-Dec; 1-2 visits per week Jan-March (scheduled flexibly around college exam timetables).
  • • Benefits: Local bus transit reimbursement, hands-on exposure to precision AI, formal certificate, and recommendation letter from Arun Patil.

For Faculty Advisors

  • • Advisory Scope: Guidance on physiological indicators, growth regulator trials, and validation methodology.
  • • Field Access: The test vineyard serves as an open outdoor laboratory for student capstone projects and observational studies.
  • • Attribution: Student and faculty contributors receive formal credit on resulting dataset releases and agronomic benchmark reports.
