Abstract :
The purpose of this study was to determine the effect and production of corn on the
application of three types of manure and doses of P fertilizer. This research was carried
out in February-June 2021 with a Randomized Block Design (RAK) with 2 factors. The
first factor is the application of three types of manure (K0): No fertilizer, (K1): cow
manure (K2): chicken manure, (K3): goat manure. The second factor is the dose of
fertilizer P (P1): 35.2 grams/plot, (P2): 70.5 grams/plot, (P3): 105.8 grams/plot.
Parameters observed were plant height, stem diameter, leaf area, wet weight per
sample, dry weight per sample, and shell weight per sample. The results showed that
the treatment with manure gave significantly different results for each parameter, while
the best treatment was the application of P2 phase on the parameters of wet weight per
sample, dry weight per sample and shed weight per sample. While in the vegetative
phase the parameters of plant height, stem diameter, leaf area gave no significant
difference.
