Biofertilisers,Organic Farming,IPM,GMO(prelims based)

• Biofertilizers are plant nutrients of biological origin like algae, bacteria, fungi which
have no harmful effect on soil and environment.

• Organic farming is a type of agriculture which avoids synthetic inorganic fertilizers,
pesticides, growth regulators and livestock feed additives.Organically grown food products are free from harmful chemicals, or typical flavoursand preservatives.

• Integrated Pest Management (IPM) is a grand idea to control pest and diseases. This
increases production, sakes the environment from pollution and harmful effects of
pesticides and saves money which is usually spent on buying pesticides.

• Biotechnology technique is used to produce plants by gene transfer (transgenics or Genetically modified organisms) whichcan be a direct answer to grow plants resistant to diseases, pests, tolerant to cold
draught and flooding etc. One can design a plant to suit this condition.

WHAT I LEFT BEHIND, WHAT I HOPE TO FIND


I left home, to come to school
I left farm, to come to food
I left my cows, my sheep,
But did not have time to weep.
Now I know why I cry tonight
’Cos I know now what I left behind
and today, what I hope to find.
Cities full of cars and bikes
Restaurants and bars and roaring mikes
But I miss the vast sky
and my kites to fly
And my folks, my friends
Seem vanishing trends
So I cry tonight but what shall I gain
Tomorrow I’ll struggle and then day after day again
