Barba’s studies on tissue culture of sugarcane, cassava, bananas, and many other horticultural crops have resulted in the enlargement of important methodologies in plant physiology and plant reproduction.
His devotion, insistence, innovativeness and optimistic approach to work efficiently in spite of inadequate resources provide as an example particularly to aspirant scientists – that one does not require extremely developed amenities and good compensation to learn something noteworthy and functional.
Barba was elected academician on 2004. His eagerness to distribute his findings to the most number of beneficiaries is shown by his dignified conclusion of not enforcing his patents so that anyone could liberally use the technology. He is unselfishly devoted to serve the industry in disseminating the technology through lectures, seminars and construction guides without material incentive.
