abstract: ABSTRACT
BEHAVIOR OF POTASSIUM EXCHANGE (Q/I), RICE PRODUCTION,
AND K ABSORPTION AS A RESULT OF MANURE AND BIOCHAR
APPLICATION ON UPLAND RICE (Oryza sativa L.) IN ULTISOL
By
ERNI TRISTIANA
Rice as one of crop commodities that has an important role in the agricultural
sector. This research aims to study: 1) the effect of manure and biochar on
potassium Q/I parameters (CRK
0, PBCK, ΔK0, KG) in Ultisol, 2) the effect of
manure and biochar on production and absorption potassium in upland rice, and
3) correlation between Q/I parameters (CRK
0, PBCK, ΔK0, KG) and CEC with
transported potassium and upland rice production due to the application of
manure and biochar. Field research was arranged in a randomized block design
(RBD) with 4 treatments, these are B0: control (without biochar and manure), B1:
biochar (5 Mg.ha-1), B2: manure (5 Mg. ha-1), and B3: a combination of biochar
(5 Mg.ha-1) and manure (5 Mg.ha-1). The results of this study indicated that 1) the
soil that was given manure and biochar with a dose of 5 Mg.ha-1 each was able to
increase the parameters PBCK and KG,but have not been increase the CRK
0 and
ΔK0 parameters; 2) application of manure and biochar, and the combination of
manure and biochar at a dose of 5 Mg.ha-1 each was able to increase production
of upland rice and K-transported in plants; 3) in the soil before planting ΔK0
parameter positively correlated with K uptake of straw. Otherwise in after
harvested soil, the KG parameters in the soil after harvest did not significantly
correlate with K uptake of straw and rice production, but were negatively
correlated with K uptake of grain.

Padi sebagai salah satu komoditas tanaman pangan penghasil beras yang memilki
peranan penting dalam sektor pertanian bagi kehidupan masyarakat. Penelitian
bertujuan untuk mempelajari: 1) pengaruh pupuk kandang kotoran ayam dan
biochar terhadap parameter Q/I kalium (CRK
0, PBCK, ΔK0, KG) pada tanah
Ultisol, 2) pengaruh pemberian pupuk kandang kotoran ayam dan biochar
terhadap produksi dan serapan unsur hara kalium pada tanaman padi gogo, dan 3)
kolerasi antara parameter Q/I kalium (CRK
0, PBCK, ΔK0, KG) dan KTK dengan
kalium terangkut dan produksi padi gogo akibat pemberian pupuk kandang
kotoran ayam dan biochar. Penelitian di lapang disusun dalam rancangan acak
kelompok (RAK) dengan terdapat 4 perlakuan yaitu B0: kontrol (Tanpa biochar
dan pupuk kandang kotoran ayam), B1: biochar (5 Mg.ha-1), B2: pupuk kandang
kotoran ayam (5 Mg.ha-1), dan B3: kombinasi biochar (5 Mg.ha-1) dan pupuk
kandang kotoran ayam (5 Mg.ha-1). Hasil penelitian ini menunjukkan bahwa; 1)
perlakuan pupuk kandang kotoran ayam dan biochar dengan dosis masing-masing
5 Mg.ha-1 mampu meningkatkan parameter PBCK dan KG, namun belum mampu
meningkatkan parameter CRK
0 dan ΔK0; 2) pemberian pupuk kandang kotoran
ayam dan biochar, serta kombinasi keduanya dengan dosis 5 Mg.ha-1 mampu
meningkatkan produksi tanaman padi gogo dan K terangkut pada tanaman padi
gogo; 3) pada tanah sebelum tanam parameter ΔK0 nyata berkorelasi positif
terhadap serapan K jerami. Sedangkan pada tanah setelah panen parameter KG
nyata berkorelasi negatif terhadap serapan K gabah, serta parameter ΔK0 dan
CRK
0 nyata berkorelasi negatif terhadap serapan K jerami dan produksi padi.
