ABSTRACT

A field experiment was conducted during 2005 - 2006 at Coimbatore, Tamil Nadu with nine
cropping systems. The systems were evaluated for their system productivity, economics and
production efficiency. Lablab – sesamum – brinjal cropping sequence registered the highest
total cotton equivalent yield (12,043 kg ha-1) and system productivity (32.99 kg ha-1 day-1).
Economic analysis revealed that the maximum net income (Rs. 44,353 ha-1) was under the
maize – cowpea – tomato sequence followed by the other sequences into which vegetable crops
were included. This system also recorded the highest economic production efficiency (Rs. 121.52
ha-1 day-1), which indicates the need for integration of vegetable crops due to higher per day
productivity over the other crops. Thus maize – cowpea – tomato sequence was identified as
the most biologically efficient and profitable cropping system followed by beet root – green
gram – maize + cowpea sequence.
