Why It Matters

Uttar Pradesh has the largest area under sugarcane cultivation and is a leading sugar producer in India. Integrating drone-based precision farming directly addresses critical challenges such as water scarcity, high input costs, and low nitrogen use efficiency. This aligns with government initiatives like the Sub-Mission on Agricultural Mechanization (SMAM) and highlights technological solutions to achieve sustainable agriculture and double farmers' income, which are recurring themes in UPPSC and UPSC exams.

Summary

Researchers at the Indian Institute of Information Technology (IIIT) have developed a dual-drone precision agriculture system that significantly reduces water and nitrogen consumption while boosting sugarcane yield and farmer profits. Conducted in Uttar Pradesh's Saharanpur district on the Co-0238 sugarcane variety, the study demonstrated a 30% reduction in irrigation water, a 24% reduction in nitrogen fertilizer, an increase in Nitrogen Use Efficiency (NUE) from 31% to 48%, and a 16.8% increase in overall crop yield, showcasing a sustainable pathway for climate-smart agriculture in India's leading sugarcane-producing state.

Key Points

  • Researchers from the Indian Institute of Information Technology (IIIT) have developed a precision farming dual-drone system designed to optimize input use in sugarcane cultivation.
  • The field study was conducted on the prominent Co-0238 sugarcane variety in Nanota block, Saharanpur district, Uttar Pradesh, and the findings were published in the journal 'Discover Agriculture'.
  • The dual-drone system works by using a first drone equipped with a multispectral camera to map crop health, nutrient deficiencies, and soil moisture, while a second drone targets fertilizer and input application specifically where required.
  • The precision technology reduced irrigation water consumption by nearly 30% (dropping from 8,900 m³/ha to 6,200 m³/ha) and nitrogen use by 24% (dropping from 250 kg/ha to 190 kg/ha).
  • Nitrogen Use Efficiency (NUE) improved from 31% to 48%, crop yield grew by 16.8% (from 78.2 tonnes/ha to 91.3 tonnes/ha), and net farm profits rose from ₹52,000 to ₹81,200 per hectare.

Prelims Trap

Under the SMAM scheme, the Central Government provides a 100% financial grant to individual farmers for purchasing agricultural drones.

100% grants are restricted to public scientific institutions (ICAR, SAUs). Individual farmers only receive up to 40-50% subsidy depending on their category, not a full grant.

Static Concepts Connected

Agriculture & Environment

What is Nitrogen Use Efficiency (NUE) and how can it be enhanced?

  • Definition: It measures the ratio of nitrogen absorbed by the crop to the total nitrogen fertilizer applied to the soil.
  • Indian Scenario: India's average NUE is low (around 30-35%), meaning more than 60% of applied nitrogen is lost to volatilization, leaching, and runoff.
  • Enhancement Tools: Enhanced using neem-coated urea, fertigation, split application of fertilizers, and targeted precision-spraying via drones.
Economy & Geography

What are the primary commercial by-products of sugarcane processing?

  • Bagasse: The fibrous residue left after juice extraction, used as biomass fuel for green power cogeneration or pulp for paper manufacturing.
  • Molasses: The dark, viscous byproduct used as the primary raw feedstock for fermenting bio-ethanol under India's Ethanol Blended Petrol (EBP) Programme.
  • Pressmud: The residue cake filtered from cane juice, used as organic manure or feedstock for Compressed Biogas (CBG) under the SATAT initiative.

Cross-Topic Patterns

  • Precision Drones + Agri-Subsidies

    Integrating Kisan Drones under SMAM with fertilizer rationalization targets demonstrates how capital subsidies are shifting toward climate-smart precision inputs to reduce import bills.

  • Sugarcane Monoculture + Varietal Breakdown

    Over-reliance on the high-yielding Co-0238 sugarcane variety highlights crop vulnerability to fungal pathogens like Red Rot, making genetic diversification a food security priority.

Prelims 2026 may contrast Kisan Drone subsidy tiers under SMAM with chemical footprint targets like Nitrogen Use Efficiency (NUE).
