Abstract

Intensification of upland sugarcane is one way to increase national sugar production. This research aimed to study the responses of growth and yield of two sugarcane varieties to residual filter cake and inorganic fertilizers in upland sugarcane. The research was conducted from August 2019 to July 2020 in the experimental field of PT Kebun Tebu Mas, Lamongan on the first ratoon cane with a split-split plot design. The treatment consisted of three factors, variety (PS 881 and PS 862 as main plots), residual filter cake (0, 5, and 10 tons ha-1) as subplots, and inorganic fertilizer residues (25, 50, 75, and 100% recommended doses about 600 kgs ha‑1 ZA and 400 kgs ha‑1 NPK 15-15-15) as sub-sub plots. The results showed that the growth and yield of PS 862 were better than PS 881 in the performance of plant height, internode length, diameter, stem length, and stem number. The residue of blotong compost had significantly better effect at the level of 10 tons ha-1 on internode length. Residual inorganic fertilizer level of 75% resulted higher leaf number, shoot number, stem number, and stem diameter. The PS 862 with 5 tons ha-1 residual blotong compost produced the highest stem weight of 0.48 kg m-1. PS 881 variety has an optimum value of 71.19% residual inorganic fertilizer to achieve a sugarcane yield of 60.31 tons ha-1.
