Penelitian ini bertujuan Untuk mengetahui seberapa besar serapan unsur hara Nitrogen, Posfor, dan Kalium oleh Padi Inpara 3 dan Padi Sikin putih dengan penambahan PKA+biochar dan pelindian. Penelitian ini dilaksanakan di rumah kaca dengan menggunakan Rancangan Acak Kelompok (RAK) faktor tunggal dengan kombinasi perlakuan, tanah saja, (tanah + padi lokal (sikin)), (tanah + padi unggul (Inpara 3)), (tanah + PKA + biochar), (tanah + PKA + biochar + padi lokal (sikin)), (tanah + PKA + biochar + padi unggul (Inpara 3)). Masing-masing perlakuan diulang empat kali.
Hasil penelitian menunjukkan bahwa pengaruh penambahan PKA + biochar belum mampu meningkatkan serapan hara oleh tanaman padi. Hal ini dikarenakan pelindian tidak dapat meningkatkan pH secara cepat. Sehingga pH tanah masih sangat rendah (pH= 2,67). Rendahnya pH menyebabkan rendahnya ketersediaan N, P dan K dan menyebabkan rendahnya serapan hara N, P dan K.

This study attempts to know how large absorption element nutrient nitrogen , posfor , and potassium by rice inpara 3 and rice sikin putih by the addition of PKA+biochar and leaching. This study was conducted in the greenhouse by using design random a group (a shelf) single factor by a combination treatment, land, (land + rice localized (sikin)), ( land + rice superior (inpara 3)), (land + PKA + biochar), (land + PKA + biochar + rice localized (sikin)), (and + PKA + biochar + rice superior (inpara 3)). Each treatment repeated four times. The research results show that the impact of the addition of PKA + biochar have not been able to increase absorption nutrient by plants rice. It was because the leaching not able to increase ph in a fast manner. Ph so that land is still very low ph ( ph = 2,67 ). The low to cause the low ph of the availability of N, P and K and the low absorption causes disturbances N, P and K. Keywords: biochar, rice, inpara 3, sikin putih, ph
