Penelitian ini bertujuan untuk mengkaji pengaruh penggunaan pupuk hayati cair penambat N2 dan tricho – kompos terhadap: 1) pertumbuhan dan produksi padi varietas Ciherang, 2) perolehan dosis dari perlakuan efektif untuk produksi padi varietas Ciherang, dan 3) korelasi serapan N dengan karakter agronomik padi varietas Ciherang. Penelitian ini telah dilaksanakan di Screen House Agronomi Fak. Pertanian Universitas Jenderal Soedirman Purwokerto dan Balitsa, Lembang, Bandung. Berlangsung selama 4 bulan, dimulai September 2015 sampai Januari 2016. Rancangan percobaan yang digunakan yaitu Rancangan Acak Kelompok (RAK) faktorial dengan 2 faktor, yaitu pupuk hayati cair penambat N2 (D) terdiri dari D0 (0 ml/ha), D1 (800 ml/ha), D2 (1600 ml/ha), D3 (2400 ml/ha) dan Tricho-kompos (T) terdiri dari T0 (0 t/ha), T1 (2 t/ha), T2 (4 t/ha) dengan 3 kali ulangan. Variabel yang diamati yaitu tinggi tanaman, jumlah anakan, luas daun, panjang akar total, bobot kering brangkasan, serapan N, jumlah gabah per malai, persentase gabah isi, bobot gabah total, bobot 1000 biji dan hasil gabah. Data hasil pengamatan dianalisis dengan uji F dilanjutkan dengan uji DMRT pada taraf kesalahan 5%. Hasil penelitian menunjukkan bahwa penggunaan pupuk hayati cair penambat N2 dan tricho – kompos mampu meningkatkan tinggi tanaman, panjang akar total, serapan N, persentase gabah isi dan hasil gabah. Kombinasi perlakuan  pupuk hayati cair penambat N2 dosis 1.600 ml/ha dan tricho – kompos dosis 6 t/ha merupakan dosis efektif  karena mampu meningkatkan produksi hasil gabah hingga 9,32 t/ha. Korelasi antara serapan N dengan persentase gabah isi dan hasil gabah tergolong tinggi.

This study aims to study the effect of using biological fertilizer liquid N2- fixing and tricho - compost on: 1) the growth and production of rice Ciherang, 
2) the acquisition an effective dose treatment for producting rice Ciherang and 
3) the correlation with agronomic characters. The research has been conducted by 4 months, starting from September 2015 to January 2016 on Screen House of Agronomy; Laboratory of Agronomy and Horticulture, Faculty of Agriculture, University of Jenderal Soedirman and Balitsa Lembang, Bandung. The experimental design was used factorial randomized block design (RBD) which first factor were biological fertilizer liquid N2- fixing consisting D0 (0 ml/ha), D1 (800 ml/ha), D2 (1.600 ml/ha), D3 (2.400 ml/ha) and second factor were tricho - compost consisting of T0 (0 t/ha), T1 (2 t/ha), T2 (4 t/ha), T3 (6 t/ha) with three repeats. The characters observed in this research were: plant height, number of tiller, leaf area, length of root total, dry weight of plant, N uptake, number of grains per panicle,  filled grain percentage, weight grain total, 1000 grain weight, and grain yield. The data were analyzed using F test followed by Duncan’s Multiple Range Test (DMRT) at level of 5% error. The result showed that the using biological fertilizer liquid N2- fixing and tricho – compost were increased on plant height, length of root, N uptake, filled grain percentage and grain yield. The combination biological fertilizer liquid N2- fixing dose 1.600 ml/ha and tricho – compost dose 6 t/ha was an effective dose cause increased grain yield until 9,32 t/ha. Correlation between N uptake with filled grain percentage and grain yield are height.
