Abstract
The present study entitled “Comparative Studies on Castor Based Intercropping Systems” was
conducted with objectives to compare sole castor and castor intercropping in terms of productivity and
to find out most suitable castor based intercropping system. For accomplishment of objectives of the
study, a field experiment conducted during 2015-2016 at Regional Research Station, Bawal (Rewari),
CCS Haryana Agricultural University. The field experiment was conducted in randomized block
design, comprising of 15 treatments with sole castor, castor + greengram, castor + sesamum, castor +
groundnut and castor + clusterbean under three level of row spacing of castor, viz. 120 cm, 180 cm and
240 cm. The results showed that significantly higher plant height and dry matter production per plant of
castor were obtained when castor crop was sown as sole castor (240 cm). Sole castor (240 cm)
recorded significantly higher number of spikes per plant, number of capsules per spike and number of
primary branches per plant followed by castor (240 cm) + greengram (1:6) intercropping. Oil content
and 100 seed weight of castor were not affected by different intercropping systems and row spacing of
castor. The mean seed yield of sole castor (120 cm) was 5246 kg ha-1, which was more than rest of the
treatments. The highest castor oil yield (2554 kg ha-1) was obtained when castor crop was sown as sole
castor (120 cm). Significantly highest castor equivalent yield (6037 kg ha-1) was obtained in castor
(180 cm) + groundnut (1:4) closely followed by castor (240 cm) + greengram (1:6) intercropping
system. Net return were greater when castor was intercropped with greengram either in 1:6 (Rs.
121455 ha-1) or 1:2 (Rs. 119986 ha-1) row proportion. The benefit : cost ratio was highest with castor
(240 cm) + greengram in 1:6 row proportion (1.79) and castor (180 cm) + greengram in 1:2 row
proportion (1.75).
