| dc.description.abstract | The development pattern of sugarcane on the island of Java has shifted to dry land because
rice fields are prioritized for other food crops. Dryland generally has low to moderate fertility
rates and water availability is a limiting factor. Silicate (Si) is a beneficial nutrient for
sugarcane and is absorbed in greater quantities than other nutrients. Si also can avoid damage
to plants against abiotic stress such as drought. This study aims to test several new high yielding sugarcane varieties under drought conditions and their responses to Si fertilization.
The design used was three-factor RAK, namely the concentration of nano-silica fertilizer (0%;
30%; 45%), watering intensity (regular watering; no watering from 45 DAS), and new high
yielding sugarcane varieties (BL; NX 01; NX 02; NX 03; VMC 86-550). The observation
variables included stover fresh weight, root fresh weight, root length, and stover dry weight.
The data obtained were analyzed by ANOVA at a 95% confidence level. If it is significantly
different, continue with the 5% LSD test. Based on the results of this study, it was shown that
the new superior sugarcane variety, namely VMC 86-550, was drought tolerant, indicated by
the best average growth in almost all observed parameters. The concentration of nano-silica
fertilizer 45% for 2 times the application showed the best growth of sugarcane. The treatment
interaction between drought and variety had a significant effect on the wet weight of stover
and root length of sugarcane. Treatment of nano-silica had a significant effect on the dry
weight of sugarcane stover. | en_US |
