No full textThe objective of this research was the effect of seed matriconditioning, application of N and P fertilizers on upland rice yields. This research was held in Cengkeh Turi, North Binjai District, Binjai City at coordinates 30 38' 24 "N - 980 28' 530 East Longitude with an altitude of ± 32 meters above sea level, from March 2022 to July. This study used a Randomized Block Design with 2 factors, namely the combination of Matriconditioning: top soil; manure; burnt husks and sawdust, and Inorganic Fertilizers: 75 kg/ha Urea, 67.5 kg/ha SP-36; 150 kg/ha Urea, 135 kg/ha SP-36 and 225 kg/ha Urea, 202.5 kg/ha SP-36. The results showed that the use of seed matriconditioning on germination, growth speed, and the best vigor index was found in manure, namely 84%, 83.3% and 72%, while the best germination rate was found in burnt husk which was 4.11. . Seed matriconditioning had a significant effect on increasing plant height from 1-5 WAP on manure and panicle number on roasted husks. Inorganic fertilizers significantly affected panicle length, grain production per plot, and leaf area. Inorganic fertilization engineering 75 kg/ha urea & 67.5 kg/ha SP-36 produced the best grain weight per plot of 393.5 grams. The interaction between matriconditioning and inorganic fertilizers had no significant effect on all observations.104 HalamanSkripsi Sarjan
