Abstract :
This study evaluated how three different
fertilizer treatment combinations affected plant height.
For specific variables or characteristics that can be
taken into account, the optimal plant height is calculated
using the first and second-order models of the
Responsive Surface Methodology. According to the
study's p-value of 0.087 for lack of fit, the Ho cannot be
entirely discounted. Thus, there is no proof that the
response surface lacks curvature or is poorly fitted. The
interaction between 100 kg/ha of poultry manure
(P/M10), 50 kg/ha of organic minerals (O/M5), and 50
kg/ha of poultry manure (P/M5) is shown by the main
effect plot, contour plot, and surface plot to be
significant at the level of 0.05. Moreover, poultry manure
at 50 kg/ha (P/M5), which spreads the longest, has the
highest impact at 100 kg/ha (P/M10) and organic
mineral at 50 kg/ha (O/M5). With the use of a Pareto
chart, that serves as the reference line. The ideal values
for the response variable for a specific location with the
accompanying expected response plant height are 101.31
cm and a composite desirability of 0.996269 to achieve
the ideal plant height. The findings of this study
demonstrate the potential of response surface analysis as
a tool for optimizing fertilizer treatment combinations
for the growth of maize. By identifying the optimal
combination of fertilizer treatments, farmers can
maximize the yield and quality of their maize crops,
while minimizing the cost and environmental impact of
their fertilizer use.
