PENGARUH KOMBINASI DOSIS PUPUK NPK DAN PUPUK KANDANG SAPI TERHADAP SERAPAN FOSFOR (P) SERTA PERTUMBUHAN DAN HASIL TANAMAN PADI (Oryza Sativa L.)

Lowland rice (Oryza sativa L.) Is a very important food crop in Indonesia because it is a staple
food and its availability must be sufficient throughout the year. Palolo subdistrict, Sigi district, is
one of the areas that has potential for food crops, especially lowland rice crops. The harvested
area of paddy fields in Sigi Regency is 30,609 ha, production is 142,564.5 dry tons of harvest
with a productivity of 4,652 tons/h. The aim of this research is that this research aims to
determine the effect of the combination of the right dose of NPK fertilizer and cow manure to
increase growth and Rice yields in Berdikari Village, Palolo District, Sigi Regency, Central
Sulawesi Province. This research was conducted in rice fields in Berdikari village, Palolo
subdistrict, Sigi district, Central Sulawesi province with coordinates 01°07'35.41"s:
120°04'59.69"e at an altitude of 679 meters above sea level, with a distance of 57 km from
Tondo. The implementation of this research will be planned for 4 months starting from July –
October 2022. This research uses a randomized block design, 5 treatments with 4 replications to
obtain 20 treatment combinations, using codes p (treatment) and u (replication) as follows: p1 =
100 kg/ha urea + 50 kg/ha phonska, p2= 50 kg/ha phonska + 5 tons/ha cow manure, p3 = 50
kg/ha phonska + 2.5 tons/ha cow manure , p4 = 100 kg/ha urea + 50 kg/ha phonska + 2.5 tons/ha
cow manure, p5 = 100 kg/ha urea + 50 kg/ha phonska + 5 tons/ha cow manure based on research
that has been done carried out, it was concluded that: 1. The parameters of plant height, number
of tillers, number of panicles and weight of 1000 grains had an influence on the administration of
various doses of NPK fertilizer, cow manure, but had no effect on the weight parameters of
harvested dry grain, milled dry grain, empty grain and Phosphorus uptake (P) 2. In the
parameters of plant height, number of tillers, number of panicles, weight of 1000 grains, weight
of harvested dry grain, milled dry grain and phosphorus uptake (P) at a dose of 100 kg/ha urea +
50 kg/ha phonska + 5 tons/ha of cow manure shows the highest average value but not for empty
grain parameters 3. Giving a combination dose of 100 kg/ha urea + 50 kg/ha phonska + 5 tons/ha
cow manure can increase yield and plant growth paddy.
