| Summary: | This research was done in the Education, Research and Agricultural Development Farm, Gadjah
Mada University, Kalitirto, Berbah, Sleman, Yogyakarta. The aim of this research was to know
influence goat manure and nature rock phosphate on N, P, K uptake and production of the sweet
corn crops in Inceptisol, Sleman. The research method was the Randomized Complete Block
Design (RCBD) with single treatment factor which three replications for each treatment. Details
of the treatment are T0: without granule manure (control), T1:granule manure 2,5 ton/ha (mixed
cattle manure and nature rock phosphate 5%), T2:granule manure 5ton/ha (mixed cattle manure
and nature rock phosphate 5%), T3:granule manure 7,5ton/ha (mixed cattle manure and nature
rock phosphate 5%). The analysis data of soil and plant growth parameters were analyzed by
multiformity investigation (analysis of variance) and if the results showed significant
differences using then Duncan Multiple Range Test (DMRT) at significant levels of 5 %. The
result showed that granule then manure was not significant influe pH, macro nutrient (N P and
K) soil and N, P, K uptake of sweet corn crops. The treatment of granule manure dosage had not
increas crop productions (cob weight, cob diameters, cob lenght and weight of 100 seeds) was
observed
