Morpho-qualitative Traits of Sugarcane (Saccharum officinarum L.) Varieties as Influenced by Seeding Density

Abstract

Response of two varieties of sugarcane namely SPSG-26 and SPSG-394 to seeding densities of 75,000, 100,000, 125,000 and 150,000 sets ha–1 was studied under field conditions. SPSG-394 produced higher cane yield (64.80 t ha–1) than SPSG-26 (52.64 t ha–1) due to higher cane density, cane length and weight cane–1. However, SPSG-26 gave higher sucrose content and commercial cane sugar (C.C.S.) percentage. Seeding densities also affected significantly cane density, cane length, weight cane–1, cane yield, sucrose content and C.C.S. percentage. A significant decrease in cane yield was observed when crop was sown with seeding densities higher than 75,000 sets ha–1. Therefore, seeding density of 75,000 sets ha–1 seems to be optimum for obtaining higher yield of sugarcane. However, maximum sucrose content (17.45%) and C.C.S. (11.87%) were obtained when crop was sown at a seeding density of 100,000 sets ha–1.
