Now an app to help farmers practice precision agriculture

[vc_row][vc_column][vc_column_text]~By T V Venkateswaran

New Delhi, June 14 (India Science Wire): Engineering students at Indian Institute of Technology Roorkee have developed a mobile app that can help farmers practice precision agriculture, particularly in application of precise amounts of fertilizers.

By determining health of the crops using hyperspectral imaging of crop leaves, the app could help in rational use of fertilizers. The development has won IIT Roorkee students the Ericsson Innovation Award 2017. Over 900 teams from 75 countries participated in the global contest for developing innovative ICT ideas on the theme of ‘Future of Food’.

Farmers apply fertilizer based on their experience rather than on any rational input. Therefore, if they chose not to apply fertilisers, perhaps they may be taking a risk and suffer economic losses. On the other hand, excessive application spoils the soil and damages the environment. “If only the farmers can know the health status of the plant, then they can make a more rational choice. The app developed by our students would be handy to the farmers. They would be able to know if the crops need fertilisers or not in just a snap,” says Prof Ajit Kumar Chaturvedi, Director, IIT Roorkee.

Named SNAP, the app uses a precision agriculture technology to determine the optimum fertiliser inputs for the crop and works on the principle of hyperspectral imaging of plant leaves. Spectral lines are like fingerprints that indicate presence or absence of a chemical by studying the light reflected by the leaf. Hyperspectral imaging combines conventional spectroscopy with imaging techniques to acquire both spectral and spatial information simultaneously for detecting physical, chemical, and biological attributes of the samples.

When the sunlight falls on a leaf, the reflected visible light and the near-infrared rays contain specific signals that tell about its chemical constituents. Water content, amount of macronutrients such as nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), calcium (Ca), as well as micronutrients such as sulfur (S), sodium (Na), iron (Fe), manganese (Mn), boron (B), copper (Cu), and zinc (Zn) and so on can be effectively measured using the hyperspectral imaging technology.

“The app uses mobile phone camera as the imaging device and hence could be profusely used in the field by the farmers,” pointed out Prof Chaturvedi.

The award winning team included Ekdeep Lubana, Anisha Godha Ankit Bagaria and Utkarsh Saxena with diverse expertise of electronics and communication, chemical and metallurgy. After an intense global competition, the team was one of the three global finalists to compete at Noble Museum in Stockholm, Sweden. The low-cost handheld imaging device for optimising fertiliser use in agricultural was declared the global winner and the team were awarded 25,000 Euro.

The jury was chaired by Sara Mazur, Head of Ericsson Research, had Caleb Harper, MIT Media Lab, Dr Catherine Mulligan, Imperial College London, Mattias Fyrenius, CEO Nobel Media, and Johan Jörgensen, Founder Stockholm FoodTech as members.

India Institute of Technology Delhi’s ICT product ‘Enigma’ that seeks to reduce weevil infestations in rice crop storage won the second place while  students of Aalto University, Finland who developed  ‘Foodgrid’, an attempt at minimizing the distance between farm and table by building a social and commercial platform to connect urban farmers, landowners with green space, and consumers won the third place.

Union Budget 2026: What the middle class gains despite no income tax slab changes

Union Budget 2026 retains income tax slabs but offers indirect relief to the middle class through TCS cuts, simpler tax filing, cheaper medicines and higher job-creating expenditure.

Union Budget 2026: what the middle class gains despite no income tax slab changes

Union Budget 2026 may not have delivered direct income tax relief to salaried taxpayers, but the government has introduced several indirect measures aimed at easing financial pressure on middle-class households.

While tax slabs remain unchanged, the Budget outlines steps to simplify compliance, reduce taxes on overseas spending, lower the cost of essential medicines, and support job creation through higher public spending.

Income tax status quo continues

The government has retained the existing income tax framework for individuals. Annual income up to Rs 12 lakh continues to remain tax-free, and with the Rs 75,000 standard deduction, effective tax-free income rises to Rs 12.75 lakh.

No changes have been announced in income tax slabs, signalling policy continuity rather than immediate relief for salaried taxpayers.

Compliance relief and tax rationalisation measures

A key focus of Budget 2026 is reducing compliance burdens and improving the taxpayer experience.

The government has proposed a reduction in Tax Collected at Source (TCS) on overseas tour programme packages to 2%, down from the earlier rates of 5% and 20%. TCS under the Liberalised Remittance Scheme (LRS) for education and medical expenses has also been cut to 2% from 5%, providing relief to families sending money abroad for essential purposes.

To ease return filing pressure, timelines have been staggered. Individual taxpayers filing ITR-1 and ITR-2 can continue to file returns till July 31, while non-audit businesses and trusts will now get time till August 31.

Protection for small investors

The Budget proposes taxing all share buybacks as capital gains instead of dividends, a move aimed at protecting minority retail investors.

In another relief measure, interest awarded by Motor Accident Claims Tribunal (MACT) to individuals will be exempt from income tax, and the applicable TDS will be removed.

A single-window system will also be introduced for submitting Form 15G and Form 15H through depositories for TDS on dividends and interest, simplifying compliance for senior citizens and small savers.

Cheaper medicines and essential products

Healthcare costs may ease slightly as the government has announced duty exemptions on about 17 cancer medicines. Personal imports of medicines for seven rare diseases will also be allowed duty-free.

In addition, customs duty relief has been extended to critical components used in the manufacture of microwave ovens, television equipment, leather goods and footwear, which could help moderate consumer prices.

Job creation through higher spending

The government has raised capital expenditure to over Rs 12 lakh crore, with allocations for railways, tourism, logistics and technology sectors. These investments are expected to support employment generation and long-term economic activity, indirectly benefiting middle-class households.

Prime Minister Narendra Modi on Saturday said the Union Budget 2026 strikes a fine balance between high capital expenditure and sustained economic growth, calling it a roadmap for long-term national development.

Speaking after Finance Minister Nirmala Sitharaman presented her ninth consecutive Budget, the prime minister said the proposals reflect a vision of trust-based governance and a human-centric economic framework. He added that India is not just focused on being the fastest-growing economy but is working towards becoming the world’s third-largest economy.

PM Modi said the Budget also reinforces India’s strong global standing and will provide fresh momentum to the country’s reform agenda. According to him, the measures announced will energise what he described as India’s “reform express”.

The prime minister highlighted the Budget’s focus on promoting tourism in the northeastern region, noting that it would create new opportunities and support regional development.

On fiscal management, the finance minister retained the states’ share in the divisible pool of central taxes at 41 per cent. She announced that Rs 1.4 lakh crore has been provided to states as Finance Commission grants for 2026–27, in line with the recommendations of the commission.

The Finance Commission, chaired by Arvind Panagariya, had submitted its report to the President in November 2025 after consultations with states and Union Territories, several of which had sought a higher share.

Sitharaman pegged the fiscal deficit for 2026–27 at 4.3 per cent of GDP, lower than the revised estimate of 4.4 per cent for 2025–26. She also said the debt-to-GDP ratio is projected to decline to 55.6 per cent in 2026–27 from 56.1 per cent in the previous fiscal.

A gradual reduction in the debt burden will help free up resources for priority sectors by lowering interest outgo, the finance minister said.

India to build seven high-speed rail corridors, Finance Minister announces

Finance Minister Nirmala Sitharaman, presenting the Union Budget 2026-27 in Parliament on Sunday, announced that India will develop seven high-speed rail corridors connecting key cities across the country.

These corridors, described as ‘growth connectors’, aim to promote environmentally sustainable passenger transport systems. The proposed high-speed rail links will connect:

  • Mumbai and Pune
  • Hyderabad and Pune
  • Hyderabad and Bengaluru
  • Hyderabad and Chennai
  • Chennai and Bengaluru
  • Delhi and Varanasi
  • Varanasi and Siliguri

In addition to passenger rail, Sitharaman announced a dedicated east-west freight corridor connecting Dankuni in the east with Surat in the west. This initiative, along with the operationalisation of 22 new national waterways over the next five years, is intended to enhance multimodal transport and reduce logistics costs.

“These initiatives will strengthen freight movement and support sustainable cargo transportation,” the Finance Minister said.

The Budget also emphasizes infrastructure development in cities with populations over five lakh (Tier II and Tier III), which have emerged as key growth centres. Sitharaman further proposed a public capital expenditure of Rs 12.2 lakh crore for the financial year 2026-27.

She outlined that the Union Budget is guided by three core responsibilities—accelerating economic growth, fulfilling aspirations, and ensuring equitable access to resources for families, communities, and regions.

Describing the plans as part of a broader reform agenda, she added, “The ‘Reform Express’ is on its way.”
