Response of Morphological and Physiological Characteristics of 4 Flood- tolerant Sugarcane (Saccharum Officinarum L.) Cultivars to ZA (Zwavelzuur Ammoniac) fertilizer application in Jember and Bondowoso

Abstract

Geography Indonesia potentially as a country producers sugar the largest in the world.Efforts to meet the demand of sugar Indonesia may be done by means the increased production of through effort extension and intensification.Business extension can be done use land marginal as land wetness.This study attempts to get doses fertilizer ZA right in apply them to several varieties cane tolerant against wetness on two different locations. Research carried out in agrotechnopark garden Jubung University Jember and gardens seed Dewisri Bondowoso start months Nopember 2015-Nopember 2016. Design experiments used design random group factorials.Factors first is doses fertilizer ZA (N), with 3 the economic situation of treatment N0: 0 kg/ha without fertilizer ZA, N1: 500 kg/ha and N2: 1000 kg per/ha.The second factor is 4 varieties (V) cane the selection results of 2014, : V1: varieties PSJT 941, V2: varieties Bulu Lawang, V3: varieties PS 865 and V4: varieties Kidang Kencana.The research results show that treatment doses fertilizer ZA 1000 kg/ha impact on a tall stems, the number of saplings, diameter of the stem and the number of segments.Treatment doses fertilizer ZA 500 kg/ha impact on number of leaves, heavy fresh header, heavy dry header, heavy fresh roots, heavy dried root, brix content, the womb sucrose and the sugar reduction.Varieties cane tolerant against wetness indicated by brix content and the sucrose is highest in varieties PS 865, then varieties Bulu Lawang, varieties PSJT 941 and varieties Kidang Kencana. The womb sugar reduction is highest in varieties PSJT 941, then varieties PS 865, varieties Kidang Kencana and Bulu Lawang.
