Abstract
An experiment was conducted to find out the effect of liquid fertilization (Magic
Growth) on performance of Kataribhog rice and to calculate how much urea can
be saved by using liquid fertilization of Magic Growth without the reduction of
grain yield. during the period of August 2013 to January 2014. The experiment
was conducted in a split plot design. Two levels of liquid fertilization and four
levels of nitrogen fertilizer were assigned to the main and sub plot. Liquid
fertilization with Magic Growth produced higher plant height, tillers hill, SPAD
value of the youngest fully expanded leaf and above ground biomass at days after
transplanting compared to no liquid fertilization treatment. All the parameters
were also increased with the increment of nitrogen level. Liquid fertilization and
increasing nitrogen fertilizer levels considerably influenced effective tillers hill’,
spikelets panicle™', grains panicle, 1000- grains weight, grain yield and straw
yield of Kataribhog rice. Liquid fertilization (L,) treatment provided greater grain
yield compared to no liquid fertilization treatment (Lo) in all nitrogen levels. With
the increment of nitrogen level the grain yield was increased up to Njoo in no
liquid fertilization treatment (Lo) but in liquid fertilization treatment (Lj), grain
yield was increased up to N7; and there after decreased in Njo0, Liquid fertilization
with Magic Growth along with 75% of the recommended nitrogen fertilizer
increased 10.5% grain yield with a saving of 25% of the recommended nitrogen
fertilizer compared to recommended practice.
Description
Rice (Oryza sativa L.) is one of the most important crops in Bangladesh. It is the
largest crop in terms of area and production in Bangladesh (BBS, 2008). Although
rice is consuming large acreage, Bangladesh is still far behind than other rice
producing countries. The average yield is very low (2 t/ha) as compared to Egypt
(8.4 t/ha) and USA (6.6 t/ha). There are many reasons for this low yield. The most
important of them is the indiscriminate and improper application of nutrients with
unfavorable condition. Many factors determine the fertilizer use efficiency for rice
crop during cultivation such as soil, cultivar, season, environment, planting time,
water management, weed control, cropping pattern, source, form, rate, time of
application and method of application (De Datta, 1978).
