Resumo: |
The present research aimed to study the productivity of five sugarcane varieties, RB867515, RB855453, RB92579, RB966928 e RB988082, by evaluating the tRTS.ha-1 (Recoverable Total Sugar) in cane-plant over the months in some regions in the State of Goiás. The experiments were conducted in 2011 in sugarcane agro-industries, located in the municipalities of Goianésia, Aporé, Goiatuba, Santa Helena de Goiás, Mineiros and Rubiataba. Experiments called maturation curve were conducted, composed of nine blocks each, containing some of the five varieties studied randomly distributed in the study sites. The experimental plot consisted of three rows of 6.0 m, spaced 1.5 m between them, and in each groove 18 gems were planted per meter. Evaluations were performed at intervals of 30 days (on average) totaling nine evaluations during the course of 497 days in 2012. Two types of sample were made, one to measure the RTS through technological analysis, and another to measure TSH (Tons of Sugar per Hectare) by weighing the total amount of production in the plot. It was found that varieties have different agro-industrial productivity in relation to harvest season and allocated environments. RB867515 variety shows tend to reach maximum productivity between the months of July and September, averaging 17 t.ha-1 for RTS, and showed an increase in productivity from April to July and decreased from September; RB966928 variety reached maximum productivity between the months from august to October, with 15 t.ha-1 approximately of RTS in august and presented mean maturation. The cultivar RB855453 reached maximum RTS productivity approximate 19 t ha-1 in September, and his maturity was mean. RB988082 variety showed mean maturation, resulting in increased RTS productivity between July and September and reaching approximately 20 t.ha-1 in September, the most productive variety when compared to the productivity of other varieties evaluated in this period as well as the most responsive to environmental conditions of the sites under study. RB92579 variety had the highest productivity from the month in July, it was found that this variety showed medium/late maturing, according to the evaluated medium, reaching maximum productivity from the month of July, and held it until the end the harvest months. |
