The Effect Of Urea On The Growth And Development Of Maize (Zea Mays) At Different Rates Of Application In The South Eastern Region Of Nigeria:- Ani, Catherine C.
ABSTRACT
The field
experiment was to study the effect of urea ( 46% N) fertilizer on the growth
and development of maize at different rates of application in South Eastern
Region of Abia State Nigeria. Completely Randomized Block Design was employed
in the experiment, comprising four treatments replicated three times to give a
total of 12 plots. Each plot had a total of nine maize stands making a total of
108 plant population. The treatments were applied at the rates of 1 0Okg/ha,
150kg/ha and 200kg/ha at the 3° and 7° week after planting. The control had no
treatment application. Plant growth and development was assessed using plant
height, number of leaves, leaf area, fresh weight and dry weight of plant.
Plant yield was assessed using fresh weight of cobs with husk, fresh of cobs
without husk and the dry weight of cobs. The data collected from different
treatment was subjected to statistical analysis using ANOV A and mean
separation was done using LSD at (p <0.05). The results were presented using
the bar chart diagrams. The results shown by the bar chart with reference to
the data collected indicated that urea applied at the rate of 100kg/ha,
150kg/ha, 200kg/ha improved the growth, development and yield of Zea mays L.
seedlings but to varying degrees. The result revealed that the maximum
vegetative growth was recorded from the treatment with the highest urea
application (200kg/ha), followed by plots treated with 150kg/ha and 1 00kg/ha
urea. Treatment application at the rate of 200kg/ha also gave the highest
result in yield of maize. Control had the lowest result at both growth and
development stages. Hence, the study revealed that urea ( 46% N) had a
significant increase (p <0.05) on the plant growth, development and yield of
maize plants.
