ABSTRACT

A good number of chewing varieties of sugarcane are being cultivated from the very old days in different
parts of the country, which is grown mostly following local and inappropriate production technologies which
gives poor yield and quality of canes. The management practices for chewing cane vary from place to place
and even from farmers to farmers. A field experiment was conducted during the year of 2016-2017 in two
district of Bangladesh which are Jamalpur and Sherpur for screening out of suitable chewing varieties in this
region. The experiment was comprising of five treatment such as T1=BSRI Akh 41, T2=BSRI Akh 42, T3=
I 61-90, T4=VMC and T5=China. The study revealed that the highest number of tiller, millable cane and yield
was found in the treatment of BSRI Akh 41, followed by BSRI Akh 42 and I 61-90 but in the economic point
of view BSRI Akh 42 was more acceptable than the clone I 61-90. But considering juice production, clone
I 61-90 is better. Therefore, the clone I 61-90 and the variety BSRI Akh 42 may be recommended for
commercial cultivation as chewing varieties in Bangladesh.
Key words: Per Sugarcane, varieties, yield.
Introduction
Sugarcane (Saccharum officinarum L.) is an important cash crop of the tropics and subtropics and main
source of white sugar in Bangladesh. Alexander’s army saw sugar cane during their conquest of India in
326 BC (Purse glove, 1989). Amongst all sugarcane growing countries of the world the position of
Bangladesh are sixteenth in respect of area and twenty-first in respect of cane production. Sugarcane
occupies 2.03 percent of net cropped area (BBS, 2005). In Bangladesh the yield of cane per unit area is the
lowest in the world (Hossain, 2001). Sugarcane juice is widely consumed by people of the tropics and
subtropics. It has been used to cure jaundice and liver-related disorders in Indian systems of medicine. The
aqueous extracts of three varieties of sugarcane showed good antioxidant properties and were also able to
protect against radiation induced DNA damage in pBR322 plasmid DNA and Escherishia coli cultures
(Lu Nai et. al., 2004). They also reported that sugarcane juice have the ability to scavenge free radicals,
reduce iron complex and inhibit lipid per oxidation, may explain possible mechanisms by which sugarcane
juice exhibits its beneficial effects in relation to its reported health benefits. Cultivation of chewing
sugarcane plastic shed used to create a microclimate in favour of chewing sugarcane growth and
encouraging early maturity. Using this method during 2002-03 in Zhejiang, China resulted in marginal
sugarcane areas in Northern China reaching early marketing, increases in stalk yields and economic
benefits. In Bangladesh, sugarcane growers follow two methods of cultivation viz. conventional and spaced
Transplanting (STP). In conventional method sugarcane setts having three buds are directly planted in the
trench, but in STP method sugarcane settlings are raised either in polythene bags or in soils bed and then
transplanted in the main field at a desired spacing. Conventional method cannot ensure regular germination
and very often gaps are found in the field. The average yield of cane in Bangladesh is very poor compared
to other developed cane growing countries like Brazil, Hawai, Mauritius, Japan, Australia etc. Temperature
and soil moisture are the two important factors affect germination of sugarcane buds under field condition.
In our country sugar and gur producing varieties are cultivated in large scale but chewing varieties are
cultivated in very limited area due to limitations of irrigation and scarcity of high land. The demand of
