ACKNOWLEDGEMENT
“A journey is easier when you travel together. Interdependence is especially
more valuable than independence”. This is the result of three years work whereby, I
have been accompanied and supported by many people. It is a pleasant aspect that I
got a golden opportunity to express my gratitude for all of them.
With great reverence, I feel it to be a privilege to express my deepest sense of
gratitude towards Chairman of my Advisory Committee Dr. (Major) G.K.
Shrivastavat, Professor, Department of Agronomy. I convey my thankfulness to him
for his overly enthusiasm, integral view on research and his mission on providing
only high quality work. Especially the extensive comments, many discussions and
interactions with him had a direct impact on the final form and quality of this thesis.
I extend my heartfelt thanks and sincere gratitude to Dr. S.K. Dwivedi,
Assistance Prof. Department of Agronomy and member of my Advisory committee for
the pivotal observation and further rectification of any reminiscent snags at important
stages of investigation. He provide me with a counting stream of meaningful feedback
throughout the observational and critical analysis of my work. I wish to express my
deep sense to gratitude to Dr. Dhananjay Sharma, Asst.Prof., Department of
Horticulture, and member of my Advisory committee, Without his continual
inspiration, sympathetic attitude, constructive criticism and incessant bearance, it
would not have been possible to this study. I wish to thank Dr. R.R. Saxena, Professor
(Department of Statistics, Mathematics and Computer Science)and member of my
Advisory committee for their co-operation, valuable suggestions for analytical part of
my thesis and healthy criticism towards completion of my thesis work.
The words at my command are definitely inadequate, to express my deep sense
of gratitude to Dr. S. R. Patel, Prof. & Head, Department of Agronomy, member of
my advisory committee for his full pledged co-operation, guidance, continued
inspiration, valuable suggestions throughout the Ph. D. programme.
I am highly obliged to Hon’ble Vice Chancellor Dr. S.K. Patil, Dr. O.P.
Kashyap, Dean, College of Agriculture, Raipur, Dr. D.A. Sarnaik, Director Research

Chandresh Kumar Chandrakar, the author of this thesis was borne
on 17th May, 1985 at Raipur (Chhattisgarh). He accomplished primary
education at his native place. He passed his high school examination from Govt
H.S. School Ravigram, Raipur (C.G.) with first division (79.2%) in the year 2001
and passed Senior Secondary Examination in mathematics science, from Govt.
Hindu Higher Secondary School Raipur (C.G.) with first division (80.4%) in the
year 2003.
In 2003 he joined the IGKV, College of Agriculture Raipur
(Chhattisgarh) and fruitfully obtained Bachelor Degree of Agriculture in the year
2007 with an OGPA of 7.67 out of 10 point scale.
Then he qualified ICAR-JRF and joined M.Sc. (Ag.) course in, 2007-
08 in his beloved subject Agronomy at College of Agriculture, Indore
(J.N.K.V.V) for specialization of Masters Degree and passed in 2009 with first
division with an OGPA of 8.01 out of 10 point scale. By completion of master
degree he joined I.G.K.V., Raipur for Ph.D. programme. He was chosen a
research problem on “Agro techniques for increasing productivity potential of
potato (Solanum tuberosum) in Chhattisgarh plain under drip irrigation” for
thesis work which has been duly accomplished by him in Ph.D. in 2012-13 and
he earned an OGPA of 8.4 out of 10 point scale. He has also qualified National
Eligibility Test (NET) conducted by ASRB, New Delhi.
Now he is going to complete his Ph.D degree program prerequisite
for submission of this thesis.
