ABSTRAK
	Penelitian ini bertujuan untuk mengetahui (1) pengaruh aplikasi pupuk N, P, dan K terhadap pertumbuhan dan hasil padi varietas Situ Patenggang, (2) pengaruh aplikasi asap cair tempurung kelapa terhadap pertumbuhan dan hasil padi varietas Situ Patenggang, (3) aplikasi  asap cair tempurung kelapa dan pupuk N, P, dan K yang mampu meningkatkan pertumbuhan dan hasil padi varietas Situ Patenggang. Penelitian dilaksanakan di Desa Cendana, Kecamatan Kutasari, Kabupaten Purbalingga pada ketinggian 360 m di atas permukaan laut (dpl). Penelitian dilakukan selama 7 bulan, dimulai bulan Maret sampai September 2016. Rancangan percobaan yang digunakan yaitu rancangan petak terbagi yang terdiri atas dua faktor. Petak utama yaitu dosis asap cair tempurung kelapa yang terdiri atas: tanpa asap cair tempurung kelapa (0 lt/ha), dilarutkan dengan rasio 1 : 100 (90 lt/ha) dan dilarutkan dengan rasio 1 : 200 (45 lt/ha). Anak petak yaitu dosis pupuk N, P, K terdiri atas 0%, 25%, 50% dan 100% (Dosis rekomendasi adalah 100 kg N/ha, 100 kg P2O5, 50 kg K2O). Variabel penelitian yang diamati antara lain tinggi tanaman, jumlah daun, luas daun, jumlah anakan, bobot tajuk dan akar, panjang malai, jumlah malai, jumlah gabah per rumpun,bobot gabah per rumpun, bobot 1000 biji, bobot biji per petak efektif dan bobot hasil per hektar. Hasil penelitian menunjukkan bahwa (1) aplikasi asap cair tempurung kelapa masih belum mampu meningkatkan pertumbuhan dan hasil padi gogo varietas Situ Patenggang (2) aplikasi N,P,K 50% hanya mampu meningkatkan karakter bobot segar tajuk vegetatif dan bobot biji isi per rumpun (3) interaksi antara perlakuan asap cair tempurung kelapa dan pupuk N, P dan K memberikan respon terhadap bobot biji per petak efektif  dan bobot per Ha namun masih relatif rendah.

ABSTRACT
	The objectives of this study were (1) Determine the effect of the application wood vinegar of coconut shell and fertilizer of N, P, K growth and yield of Situ Patenggang upland varieties, (2) Determine the application wood vinegar of coconut shell and fertilizer N, P, and K were able to increase the growth and yield of Situ Patenggang upland varieties, (3) application of wood vinegar of coconut shell and fertilizer N, P, and K were able to increase the growth and yield of rice varieties Situ The research was conducted in the village of Cendana, District Kutasari, Purbalingga at an altitude of 360 m above sea level (asl). The study was conducted for 7 months, started in March to September 2016. The experimental design was a design of split plot design consist of two factors. The main plot is the dose of wood vinegar of coconut shell as main plot, with a concentration no application (0 lt / ha), dissolved with a ratio of 1: 100 (90 l / ha) and dissolved with a ratio of 1: 200 (45 lt / ha). The sub plots is the dose of fertilizer N, P, K as subplot 2, consisting of 0%, 25%, 50% and 100% (dosage recommendation is 100 kg N / ha, 100 kg P2O5, 50 kg K2O). Research variables observed were plant height, leaf number, leaf area, number of tillers, the weight of the canopy and roots, panicle length, number of panicles, number of grains per panicle, grain weight per panicle, weight of 1000 seeds, seed weight per plot effective and weights results per hectare. The results showed that (1) application of wood vinegar of coconut shell has not been able to increase growth and yield, (2) However, to increase the efficiency of N, P, K 50% on the character of vegetative canopy fresh weight and content of grain weight per clump, (3) interaction between liquid smoke coconut shell and fertilizer N, P and K afford respond to the grain weight per plot effective and weight per ha, but relatively low.
Keywords: wood vinegar of coconut shell, N,P,K fertilizer, upland rice of situ patenggang
