ABSTRACT<br />Application of organic fertilizer into the soil is designated as a source of macro, micro nutrients and organic acids; it also acts as soil ameliorant that improve physical, chemical and biological properties of soil. Application of high rates organic fertilizer has a constraint namely the availability and ease of application. Therefore, it is necessary to learn the use of organic fertilizer with low rates to improve the efficiency of chemical fertilizers. This research was aimed to study the effect of organic and inorganic fertilizers on growth and yield of paddy rice, as well as the efficiency of N, P, K inorganic fertilizer. Field experiment was conducted at Sawah Baru Research Station, University Farm IPB, Bogor, West Java from September to December 2013. The experiment used Randomized Block Design consisted of two factors: rates of organic fertilizer (0, 250, 500, 750, and 1,000 kg ha-1), and rates of inorganic fertilizer (0, 100, 200, 300, and 400 kg ha-1). The results suggested that the application of 1,000 kg organic fertilizer ha-1 + 400 kg inorganic fertilizer ha-1 did not show significant interaction. Application of organic fertilizer alone up to 1,000 kg ha-1 resulted in low growth and yield. Increasing rates of  application up to 400 kg inorganic fertilizer ha-1 increased the growth and yield of paddy rice. The highest N efficiency was 89.19% at a rate of 500 kg organic fertilizer ha-1 + 200 kg inorganic fertilizer ha-1, whereas the highest efficiency of P and K, respectively were 69.55% and 92.52% at a rate of 750 kg organic fertilizer ha-1 + 300 kg inorganic fertilizer ha-1.<br />Keywords: NPK, organic fertilizer, paddy rice

<p>Abstract : One of the efforts to increase the productivity of paddy rice by setting the<br />right spacing. At this time,  developing technology engine planting of rice seedlings<br />(rice transplanter) which introducing plant spacing ranging from narrow spacing to<br />large plant spacing both on legowo row planting system and tile planting system. With<br />regard to the introduction of these technologies, further research is needed in the<br />effect of plant spacing on growth, productivity (grain yield) and income of paddy rice<br />farmers. The assessment was carried out on the wetland of farmer group of Rukun<br />Tani Sulur  Blimbing Village of Sragen Regency on July – October 2014. The<br />assessment consisted of 3 planting distance treatment of legowo row 2: 1 planting<br />system, ie 20 x 10 x 40 cm, 20 x 13 x 15 cm and 20 x 15 x 40 cm, each treatment<br />repeated 7 times. The area of each treatment is about 0.33 ha. The assessment<br />involves 7 farmers, each farmer carrying out 3 treatment. The seedlings using legowo<br />2:1planting system of rice transplanter. This rice transplanter has 3 combination of<br />plant distance, that is 20 x 10 x 40 cm, 20 x 13 x 15 cm and 20 x 15 x 40 cm. The data<br />collected includes the number of productive tillers, productivity, input and output of<br />farming. Data analysis to compare between 3 treatment by using paired t test. While<br />the analysis of financial feasibility of paddy farming technology using partial budget<br />analysis. The results of this assessment showed that a legowo row 2:1 planting system<br />with plant distance 20 x 15 x 40 cm resulted in highest productive tillers, productivity<br />and income compared to the legowo 2:1 with a narrower plant distance 20 x 10 x 40<br />cm and 20 x 13 x 40 cm.</p><p> </p><p>Abstrak: Salah satu upaya untuk meningkatkan produktivitas padi sawah melalui<br />pengaturan jarak tanam yang tepat. Pada saat ini, berkembang teknologi mesin tanam<br />bibit padi (rice transplanter) yang mengintroduksikan jarak tanam mulai dari jarak<br />tanam sempit sampai dengan jarak tanam lebar baik pada sistem tanam jajar legowo<br />maupun sistem tanam tegel. Berkenaan dengan introduksi teknologi tersebut perlu<br />dilakukan penelitian lebih dalam pengaruh jarak tanam terhadap pertumbuhan,<br />produktivitas (hasil gabah) dan pendapatan petani padi sawah. Pengkajian<br />dilaksanakan pada lahan sawah kelompok tani Rukun Tani Sulur  Desa Blimbing Kec.<br />Sambirejo Kab. Sragen Jawa Tengah pada MT-3 2014. Pengkajian terdiri dari 3<br />perlakuan jarak tanam pada sistem tanam jajar legowo 2:1, yaitu  20 x 10 x 40 cm, 20<br />x 13 x 15 cm dan 20 x 15 x 40 cm dengan 7 kali ulangan. Luas masing-masing<br />perlakuan sekitar 0,33 ha.  Pengkajian melibatkan 7 orang petani, setiap petani<br />melaksanakan 3 perlakuan. Tanam bibit padi menggunakan mesin tanam bibit padi  4<br />baris sistem tanam jajar legowo 2:1. Mesin tanam ini mempunyai 3 kombinasi  jarak<br />tanam, yaitu  20 x 10 x 40 cm, 20 x 13 x 15 cm dan 20 x 15 x 40 cm.  Data yang<br />dikumpulkan meliputi jumlah anakan produktif, produktivitas, input dan output<br />usahatani.  Analisis data untuk membandingkan antara 3 perlakuan jarak tanam dilakukan uji t berpasangan dengan menggunakan software SPSS Statistics 17.0. <br />Sedangkan analisis kelayakan finansial teknologi usahatani padi sawah menggunakan<br />analisis anggaran parsial.  Hasil pengkajian menunjukkan bahwa sistem tanam jajar<br />legowo 2:1 dengan jarak tanam lebar (20 x 15 x 40 cm) menghasilkan jumlah anakan<br />produktif,  produktivitas dan pendapatan yang lebih tinggi dibandingkan sistem tanam<br />jajar legowo 2:1 dengan jarak tanam yang lebih sempit (20 x 10 x 40 cm dan 20 x 13 x<br />40 cm).</p>
