Welcome you all to the new course what has
been floated the title is nanotechnology in agriculture. So this is a course which encompasses basic
understanding of agriculture and the agrochemicals starting from fertilizers to insecticide to
pesticides the matter of fact all the way up to post harvest technology where the Agro
product are to be preserved. In all the scheme of things, the modern day
agriculture if we look back very early or earlier half of 19th century with the synthetic
processes, Haber process and several other technological breakthroughs which led to the
use of fertilizer followed by a series of chemically synthesized pesticides. So essentially the modern day agriculture
is a very chemically intensive industry. But with the issues of soil pollution, water
pollution, water contaminants because of the fertilizer residues, soil salinity problem,
soil acidity problem and resistant of the crops to its several pest one need to rethink
and there is a rise of several sustainable technologies which are being encouraged and
there is another technology which is coming called precision agriculture where just for
an example if you think that you know you are spreading fertilizer all over the field. But the precision agriculture says that you
only apply at the precise point where the specific plant will get maximum benefit. This is just an example. There is lot of whole field of precision agriculture
which is coming up. So more and more you are realizing wanton
use of chemical needed to be curved out. So one of the approach which is slowly gaining
prominence is the role of nanotechnology where you can develop these chemicals at the nano
scheme using different nano scheme at the nano dimension. And if you couple it with precision agriculture
technique and more innovative ways one can really harness or reap a lot of benefit. Of course with the word of caution that when
chemicals become popular in agriculture there was a wanton use of it and that led to a lot
of problems but as you learn from history if we keep that in mind that what all mistakes
mankind has done and if we embrace the power of nanotechnology to increase our yield, increase
our food grain production, preservation of food grains as well as pest control for the
food grains. We can make a huge difference in the years
to come. As it is evident that agriculture production
has to go up because population is rising so in this light we probably need to think
very wisely yet we have to ensure that for the posterity we do not destroy all our resources
that they suffer. So keeping all this in mind a judicious use
of nanotechnology could come up as a very profound tools for the future. So this course will take you from the basics
of agriculture and the history of agriculture and those landmark discoveries we change the
concept of agriculture itself to all the way the modern time when we are assuring into
a new era where nanotechnology based technologies are slowly gaining significance and prominence
among the farmers and as a matter of fact while I did my agriculture training. There was not such course because nanotechnology
was not even, this is way back in 1980s there was no such concept even as a matter of fact
out there but today almost how I would say 28 or 3 decades later while I will be teaching
an agriculture course. Nanotechnology is the next wave or we are
already into that wave and I believe it is the right time we should share all the available
information’s about nanotechnology based application in agriculture starting from sea
treatment all the way to plant treatment to food preservation or post-harvest technology
as well as for pest control. And what are all the legal matters what we
have to take into account and how carefully we have to deal with these new tools, which
have tremendous power yet has to be used very judiciously. So once again welcome you all for this new
course which is a 20-hours course essentially will be having 40 lectures throughout and
I will try to cover horizontally as much as new and newer technologies which are there. So mostly the course will involve the journal
papers which have been published because it is very tough to get one book where everything
will be covered because this is still subject is in its infancy so it will be mostly I will
be teaching from all the recent papers what have been published technologies which are
slowly gaining prominence. So once again I welcome you all and let us
have a wonderful journey of realizing how the agricultural shape up in the coming decades. Thank you.
