3. SUGARCANE In agriculture sector, sugarcane shared is about 7% of the total value of agriculture out put and occupied about 2.6% of India’s gross cropped area during 2006-07. Sugarcane provides raw material for the second largest agro-based industry after textile. About 527 working sugar factories with total installed annual sugar production capacity of about 242 lakh tonnes are located in the country during 2010-11. 1 Scientific name of Sugarcane: The genus Saccharum has five important species viz., Saccharum officinarum , S. Sinense , S.barberi , S.robustum , S.spontanuem . The first three species are the cultivated species and the last two are wild ones. S. officinarum species is widely cultivated in India because of high sucrose content.

5. Treatments comprising 12 combinations, 6 cropping systems, viz. sole sugarcane, sugarcane + lentil /mustard /maize / rajmash /rapeseed, as intercrop and 2 row spacings for sugarcane planting, viz. 75 cm, and 90 cm were tested in randomized block design. All the intercrops except maize, reduced cane yield attributed to decline in number of millable canes. Mean reduction in cane yield was 8.7% with lentil, 14.8% with mustard, 13.3% with rajmash and 8.7% with rapeseed. Sugarcane planted at 90 cm spacing produced 9.5% higher cane yield than that at 75 cm. Sugarcane + maize gave the highest mean cane-equivalent yield (200.6 tonnes /ha) being 52.5, 45.4, 55.7, 50.0 and 48.6% higher than sole sugarcane and its intercropping with lentil, mustard, rajmash and rapeseed, respectively. Sugarcane intercropped with maize gave highest net return of Rs 124,874/ha followed by sugarcane alone (Rs 71,145) as against Rs 62,104; 65,067; 67,138 and 69,040 with intercropping of mustard, rajmash , rapeseed and lentil respectively. Row spacing for sugarcane of 90 cm gave higher cane equivalent yield and monetary return over 75 cm. [lentil: Lens culinaris Medikus ; mustard: Brassica juncea (L.)
