HP UHF Camp 2018

Solan:  Nauni-based Dr YS Parmar University of Horticulture and Forestry (UHF) today organized a one-day demonstration camp on the ‘Role of Managed Pollination in Apple Orchards’.

Apple farmers from Shimla, Chamba, Sirmour and Mandi district districts of Himachal Pradesh received practical lessons in managed pollination

The lack of managed pollination especially honey bee colonies is taking a toll on the agricultural output of the state and resulting in poor fruit set and low productivity. This eventually led to the loss of income for farmers, noted Dr Anju Khanna, Head, UHF’s Department of Entomology.

Role of Managed Pollination in Apple growing

Besides general information about the importance of beekeeping, the farmers also learned about the identification of important insect pollinators and the strategies to conserve them.

Dr Harish added that the main idea is to apprise the farmers on the vital role played by bees and other insect pollinators and motivate them to implement it in their orchards and reap its benefits.Farmers at the University apiary

Moreover, the farmers were given a live demonstration at the university apiary where topics like transportation of bee colonies and bee management were discussed.

They also learned how to protect the bees in case there is a need to use spray on the trees/fields. Field visit to the high-density plantations of newly introduced apple varieties under the HPHDP project was also undertaken where the forager behaviour of the bees was explained to the farmers.

The nodal officer of the project in the university is Dr JN Sharma, who is also the Director Research of the university. The university scientists have been part of the project for the past two years.

Explaining about the camp, project coordinator Dr Harish Sharma said,

The activity aims to explain the topic of managed pollination. Thorough practical sessions on the preparation of honey bee colony for pollination and the use of pollen dispenser for ensuring proper pollination in apple were organized for the participants, who all happen to be progressive apple growers.

The camp organized under the World Bank funded Himachal Pradesh Horticulture Development Project (HPHDP). Fifty-two persons, who are ‘contact farmers’ and stakeholders in the project, attended the camp, along with 12 officers of the Horticulture Department.

Watch: IIT Mandi Researchers Use ‘Pollutant Diesel Emissions’ For Water Treatment

IIT mandi uses diesel soot sponge for water treatment

Mandi- Researchers at Indian Institute of Technology Mandi have used the soot emitted by diesel engines to mop up oil and other organic pollutants from water. Their work has been recently published in the journal – Environmental Science and Pollution Research.

Although diesel engines are known to be superior to other internal combustion engines in terms of lower fuel consumption and better energy release efficiencies, they are associated with significant amounts of particulate emissions.

 The particulates largely comprise soot, which is formed in the fuel rich regions of the burning diesel jets. Increasing environmental concerns and stringent emission standards require the development of both conventional and unconventional means for reducing soot.

 Studies in this area have focused on improving the engine design and incorporating special filters and treatment units at the exhaust end of the vehicle.

Dr. Rahul Vaish, Associate Professor, School of Engineering at IIT Mandi and his research students Vishvendra Pratap Singh and Moolchand Sharma have looked at this problem from a different perspective.

They rationalized that while it is impossible to bring down soot emissions to zero, it is possible to find a use for the soot produced.

 Carbon species such as carbon nanotubes, graphene, and candle soot have shown their potential in many fields,

says Dr. Vaish,

so why not automobile soot?

It is known that carbon species can absorb various organic pollutants in water. Carbon nanotubes, filter paper, mesh films, and graphene have been used for removing oil from water. Given that the typical carbon content of soot is between 90 and 98%, the team explored the possibility of using this pollutant as an adsorbent of oil and organic contaminants in water.

 There is a rapid increase in oil and chemical leakages from oil tankers or ships and industrial accidents with expansion in oil production and transportation in the last few decades,

the authors write in their recently published paper, justifying the need for new materials to mop up oil and prevent catastrophic environmental outcomes.

 In an earlier study, Dr. Vaish used candle soot to successfully remove two cationic dyes, rhodamine B and methylene blue from water, thereby showing the possibility of organic from water thereby showing the possibility of organic chemical removal by soot. Extending this earlier work, the research team incorporated diesel exhaust soot into polymer sponges to study their capability to adsorb oil and other organic materials from water. This hydrophobic sponge showed high absorption capacity for various oils, without the need for complex pretreatments.

The researchers found that the highest oil absorption capacity was 39 g/g for engine oil. An interesting observation was that the sponges were recyclable and retained 95% efficiency even after 10 cycles.

The diesel soot impregnated sponge could also absorb pollutants like methylene blue, ciprofloxacin, and detergent from the water. This has practical implications.

Apart from oil spills, organic pollutants such as traces of dyes and detergent coming from industries and households are a major contributor to water pollution,

says Dr. Vaish.

The soot impregnated sponge can help in developing cost-effective remediation processes for common domestic and industrial pollutants. Such a development would additionally serve to repurpose automobile waste.

Disabled HPU Students Clears UGC NET

Shimla-Crossing milestones in academics, disabled students of Himachal Pradesh continue to achieve what is otherwise considered insurmountable for them.

Eleven differently-abled students have cleared UGC’s National Eligibility Test (NET). Two of them qualified for the Junior Research Fellowship. Five of these students are visually impaired.

It’s important to mention that disabled students had to fight a legal battle to claim their right to higher education in Himachal Pradesh University. Even after ‘The Rights of Persons with Disabilities Bill – 2016’ was passed, the students had to fight for its implementation as the government did not make it easy for them.

Two students who qualified for the JRF include Saveen Janha, an M.Phil in Hindi, and Pankaj Sharma, P.hD in Tourism Administration. Both are physically disabled, informed Ajai Shrivastava, a member of the State Advisory Board on Disability and HPU Executive Council (EC).

Indu Kumari, a visually impaired student, who is pursuing her M.A. in Political Science, cleared the NET examination in her very first attempt. Similarly, visually impaired Roma Negi, a resident of Rampur, has cleared the exam in History in her first attempt. She wants to pursue her P.hD from HP University.

Other names include Anuj Kumar (Economics), Vinod Sharma (Political Science), Jasbir Lubanand (Political Science), Vinod Sharma Yogacharya (Yoga), Priyanka Thakur (Law), Ajay Kumar (History). Some of these students have cleared the NET examination twice. Raj Kumar is a Ph.D in Education and has cleared the NET exam in the same. He had also passed the NET examination in History and this time cleared the exam in Political Science.

The Vice-Chancellor, Prof. Sikander Kumar has congratulated all these students and appreciated their hard-work despite facing hardships due to their disability. He said these students have brought laurels to the State.
