Rice is the main crop in Indonesia due to its status as staple food. Therefore, the development engineering of various rice varieties is also very rapid in Indonesia. Rice can grow well in Indonesia with an average yield of 5-6 tons / ha (BPS, 2016). These results have not shown a significant increase over the past 10 years. Although the technology of rice cultivation has been developed, various constraints limit the significant increase in rice yields. Thus, providing appropriate technology in

One of the efforts to increase the yield of rice plants is to trim the foliages before flowering, in addition to the application of 'Unitas Super' liquid organic fertilizer (LOF). The study was carried out in the Lubuk Lintah Village, Padang City in May -September 2017. The aim of the study was to investigate the effectiveness of pruning, as a source of forage, and the concentration of 'Unitas Super' liquid organic fertilizer in improving rice yields. The experiment was arranged in split plot design with main plots consisting of 2 levels, namely pruning at 45 days and without pruning. The subplots consisted of 3 concentrations of 'Unitas Super' liquid organic fertilizer, namely 0 ml L -1 , 50 ml L -1 , and100 ml L -1 . All treatments were replicated 3 times. Data were analyzed statistically using the F test at 5% and tested using LSD at 5%. According to the results of the observations, it can be concluded that pruning reduced the weight of 1000 seeds and panicle length, but did not reduce the yield of harvested dry grain and harvest index. Application of 'Unitas Super' liquid organic fertilizer did not significantly increase the growth and yield of Black Madras purple rice. The highest dry grain yield was 4.04 t ha -1 observed in plants sprayed with 50 ml L -1 'Unitas Super' liquid organic fertilizer without pruning treatment. ABSTRAK Produksi beras Indonesia masih relatif rendah. Salah satu upaya untuk meningkatkan hasil tanaman padi adalah dengan memangkas dedaunan sebelum berbunga, di samping penerapan pupuk organik cair (LOF) 'Unitas Super' . Penelitian dilakukan di Desa Lubuk Lintah, Kota Padang pada bulan Mei -September 2017. Tujuan dari penelitian ini adalah untuk menyelidiki efektivitas pemangkasan, sebagai sumber pakan, dan konsentrasi pupuk organik cair 'Unitas Super' dalam meningkatkan hasil padi. Percobaan disusun dalam desain petak terbagi dengan plot utama yang terdiri dari 2 level, yaitu pemangkasan pada 45 hari dan tanpa pemangkasan. Sub-plot terdiri dari 3 konsentrasi pupuk organik cair 'Unitas Super' , yaitu 0 ml L -1 , 50 ml L -1 , dan 100 ml L -1 . Semua perawatan diulang 3 kali. Data dianalisis secara statistik menggunakan uji F pada 5% dan diuji menggunakan LSD pada 5%. Menurut hasil pengamatan, dapat disimpulkan bahwa pemangkasan mengurangi berat 1000 biji dan panjang malai, tetapi tidak mengurangi hasil panen gabah kering dan indeks panen. Penerapan pupuk organik cair 'Unitas Super' tidak secara signifikan meningkatkan pertumbuhan dan hasil beras ungu Madras Hitam. Hasil gabah kering tertinggi adalah 4,04 t ha -1 yang diamati pada tanaman yang disemprot dengan 50 ml L -1 'pupuk organik cair Unitas Super 'tanpa perawatan pemangkasan.
