AUDE, Maria Isabel da Silva; MARCHEZAN, Enio; PIGNATARO, lone Aidee Bernardes  e  PASQUALETTO, Antonio. PLANTING DATES AND ITS EFFECTS ON PRODUCTIVITY AND BRIX % JUICE OF SUGARCANE. Cienc. Rural [online]. 1992, vol.22, n.2, pp.131-137. ISSN 0103-8478.  https://doi.org/10.1590/S0103-84781992000200002.

The experiment was conducted at the Federal University of Santa Maria with the objective of verify the planting date of sugarcane that will lead to increased yield and brix. Were tested two sugarcane varieties (NA 56-79 and IAC 50-1345) in eight planting dates. The planting dates were monthy from August, 15, 1985 to March, 15, 1986. There was not difference between the sugarcane planted in August and September, and between varieties for productivity. In the harvest of plant-cane, the mean productivity was 82,5t/ha, for these two planting dates. Sugarcane planted in August-September had higher productivity when harvest was done 12 months after planting time. Sugarcane planted in January/1986 and harvested 19 months later had a higher production of industrialized culms (167.2ton.ha) and was different from the ones planted in October/85, January, February and March/86. In planting time of January, February and March the productivity was higher when the plant-cane was harvested 18 months later. The average Brix for the August and September plantings was 19,8% independent of cultivar. The highest Brix average was observed in sugarcanes planted in February (20,1%) which was different from other planting dates.
