Response of Fourth Ratooning of Sugarcane to Different Patterns of Plantation and Seeding Densities

Abstract: Planting pattern and density effects on various agronomic traits of the fourth ratoon of sugarcane genotype SPSG-394 were determined during 1998-99 at the University of Agriculture, Faisalabad (Pakistan). Plant crop was raised during 1993-94 in three planting patterns, i.e. 100-cm spaced 100×100 squarish pits, 100-cm spaced circular pits with a diameter of 1 m and 90-cm spaced 2-row strips (30/90 cm) flat sowing at seeding densities of 10, 15, 20 and 25 buds m^–2, using randomized complete block design. Ratoon of the crop planted in 90-cm spaced double-row strips (30/90 cm) gave significantly higher cane yield ha^–1 than pit plantation while the converse was true for the sucrose content. Planting densities used for the plant crop had little effect on stripped cane yield but had significant effect on sucrose content. Ratoon of the crop planted at the lowest seeding density (10 buds m^–2) produced juice with the maximum sucrose content against the minimum with a seeding density of 25 buds m^–2. Interactive effect of planting pattern and seeding density on stripped cane yield, sucrose content and purity of juice was non-significant. The results suggest that sugarcane should be planted in 90-cm spaced double row strips at a seeding density of 25 buds m^–2 in order to maximize can yield ha^–1 of the ratoon crop while pit plantation be preferred for improving sucrose content and purity of cane juice.
