Abstract :
Abstract – A field experiment was undertaken on
"Cropping System Diversification Studies" at Agricultural
Research Station, Siruguppa under University of
Agricultural Sciences, Dharwad (Karnataka). The soil type
was deep black with pH 8.2. The available NPK contents in
soil were 205, 32 and 485 kg/ha, respectively. Yield data
pooled during rabi/summer indicated that significantly higher
yield (28000 kg/ha) was recorded in ridge gourd followed by
tomato (26598 kg/ha) and radish (11064 kg/ha). Highest rice
equivalent yield (26518 kg/ha) was recorded in riceridgegourd
cropping system, which was followed by ricetomato
(1671 kg/ha), rice-clusterbean (11810 kg/ha) and riceradish
(10313 kg/ha), when compared to existing rice-rice
(6953 kg/ha) system. Gross return, net return and B:C ratio
were also higher in rice-ridgegourd cropping system (Rs.
201217, Rs. 166485 and 5.79, respectively), when compared to
the other systems and rice-rice cropping system alone.
