Abstract
Abstract Article Information
Lack of appropriate agronomic practices related to fertilizer management is a major
constraint to enhancing sugarcane yield in Ethiopia. The effect of optimum rate and time of
blended fertilizer application on yield and quality of ratoon commercial crop is not known at
Arjo Didessa Sugar factory. Therefore, the field experiments were conducted with the
objectives of assessing the effect of blended fertilizer at different rate and time of application
on Ratoon sugarcane growth and yield of cane. The treatments consisted of eight levels of
blended fertilizer with N (0, 150, 111N, 200 and 103N, 250 and 94N, 300 and 85N, 350 and
76.4N, 400 and 68N kg ha-1 and recommended fertilizer rate) and two times of application
(one and two month after harvest). The field experiments were laid out as Randomized
complete block design in a factorial arrangement and replicated three times. A sugarcane
cultivar named N-14 was used as a ratoon material. Analysis of variance of the data
revealed that the blended fertilizer application rate had significant effect on ratoon weight per
stalk, node number, plant height, node length and cane yield sugar yield. Blended fertilizer
rate and time of application and their interaction showed only highly significant on stalk girth
and stalk population and interaction was significant effect on weight per stalk and node
length at the time of harvest. However, application of blended fertilizer at different time and
their interaction on plant height, cane yield and node number did not showed significant
effect. Blended fertilizer treatment with the rate of 250kg ha-1 blended fertilizer mixed with
94kg N ha-1 at one month after harvest resulted in higher ratoon cane weight per stalk, stalk
girth, cane yield, sugar yield, node length, stalk population and node number. Therefore,
highest cane yield was recorded at late application time of blended fertilizer at lower dose
and higher dose of nitrogen. Therefore, treating the ratoon cane by 250kg ha-1 BLF with 94kg
N ha-1 at one month after harvest had evidently the advantage of improving ratoon cane
growth and yield performance.
