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. kata kunci: biochar, padi, inpara 3, sikin putih, ph

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
