A trial was conducted during 2007 to 2009 at research farm of All India Coordinated
Research Project for Dryland Agriculture, Phulbani in the North-Eastern Ghats
Zone of Odisha with an objective to assess crop compatibility, productivity,
profitability and sustainability of trailing vegetable + maize intercropping systems.
Maize crop was sown during the second fortnight of June and vegetables were sown
15 days after sowing (DAS) of maize. Among the vegetables in maize based
intercropping systems, ridge gourd (Luffa acutangula Roxb.) recorded the highest
yield of 5.98 t ha-1 followed by cucumber (Cucumis sativus L.) (5.12 t ha-1 ) and cowpea
-(Vigna sinensis Savi) (3.04 t ha -1). The highest green cob equivalent yield of 16.60 t ha-1
was observed with maize + ridge gourd system which was at par with maize + cowpea
system (16.52 t ha-1 ). Among different systems, maize + ridge gourd was the most
-profitable with average net return of ` 45,000 ha-1 and B:C ratio of 2.18 followed by
maize+cowpea with net return of ` 44,600 ha-1 and B:C ratio of 2.17. The highest net
energy output was observed with maize + cowpea (13,244 MJ ha-1 ) followed by maize
+ ridge gourd (10,363 MJ ha-1 ). Maize + ridge gourd system recorded the highest
rainwater use efficiency (RWUE) (14.52 kg ha-mm-1 ) followed by maize + cowpea
(14.45 kg ha-mm-1 ) compared to sole maize of 9.30 kg ha-mm-1 . Nutrient uptake
studies indicated that maize + cowpea system provided net positive nitrogen balance
of 25.1 kg ha-1 . In all the intercropping systems, phosphorus recorded net negative
balance and potassium recorded net positive balance at the end of cropping season
irrespective of intercropping systems.
