Growth and Production of Three New Rice Varieties in Prima Tani Mandailing Natal. The use of New Rice Superior Variety has a future prospect. It is not only high productivity but also reduces the risk of crop failure. This Assessment was aimed to study growth performances, yield component, and production of three types of New Rice Superior Varieties of Seed Stock (SS) at Prima Tani Location in Ipar Bondar Village, Mandailing Natal District, North Sumatera. The study was done by 5 farmers in their own rice field with total of farm area used was 4 ha. Cultivation for seed production of new seed variety (NSV) was done in dry season (March-July 2008), while seed processing was executed in August 2008. Rice varieties used were Mekongga, Conde dan Angke. The seeds used was originated from Indonesian Center for Rice Reseach at Sukamandi, with the method of paddy cultivation followed the Integrated Crop Management (ICM) approach. The research used a Random Block Design with 5 repetation. The result showed that Mekongga variety gave highest yield of 8.30 t/ha , Conde 7. 7 t/ha, and Angke 7.80 t/ha. Data were analysed using descriptive of rice productivity to compare rice productivity among varieties. Improvement productivities of Conde, Angke, and Mekongga was .67-2.80 t/ha (the average of 2.26 t/ha) or increase between 30.36 - 50.90% (with the average of 4 .09%), compare with Ciherang (5.5 t/ha) in location area. Total rice seed production of SS seed class was 38.5 t. The seed of NSV was sold Rp.5,200/kg per package and has been distribute to 37 villages of 0 sub-districts in Mandailing Natal District. It was concluded that the Mekongga variety gave the highest yield of 8.3 t/ha of dry grain harvested, compare with two other variety. Thus, these varieties can be developed for seed multiplication. While, Conde and Angke varieties are also an alternative varieties to be developed in this location because their production are also high. Key words: Paddy seed source, new rice superior variety Penggunaan Varietas Padi Unggul Baru ditingkat petani cukup prospektif, selain memiliki produktivitas yang tinggi juga mengurangi resiko gagal panen. Pengkajian ini bertujuan untuk mengetahui keragaan pertumbuhan, komponen hasil dan produksi tiga jenis benih sumber padi Varietas Unggul Baru (VUB) di lokasi Prima Tani di Kabupaten Mandailing Natal. Pengkajian ini melibatkan 5 orang petani di lahan sawah milik petani di Desa Ipar Bondar, Kecamatan Panyabungan, Kabupaten Mandailing Natal. Total luas lahan yang digunakan 4 ha. Penanaman padi VUB untuk produksi benih dilaksanakan pada MK Maret-Juli 2008 sedangkan prosesing benih dilaksanakan pada bulan agustus 2008. Benih padi yang diproduksi meliputi: Mekongga,Conde dan Angke. Benih yang digunakan berasal dari Balai Besar Penelitian Tanaman Padi Sukamandi. Dalam penanaman padi menggunakan pendekatan model PTT. Rancangan yang digunakan Acak kelompok dengan 5 ulangan. Hasil penelitian menunjukkan varietas Mekongga memberikan hasil tertinggi yaitu 8.30 t/ha, disusul varietas Conde 7. 7 t/ ha dan Angke 7.80 t/ha. Data produktivitas antar varietas dikumpulkan juga dianalisis secara deskriptif untuk membandingkan produktivitas Keragaan Pertumbuhan Komponen Hasil dan Produksi Tiga Varietas Padi Unggul Baru di Lokasi Primatani Kabupaten Mandailing Natal (Khadijah El Ramija, Novia Chairuman, Didik Harnowo) 43 antar varietas. Peningkatan produktivitas Conde, Angke, dan Mekongga adalah .67-2.80 t ha- (rata-rata 2.26 t/ha) atau terjadi peningkatan antara 30.36-50.90% (rata-rata 4 .09%) dibandingkan dengan Ciherang (5.5 t/ha) yang ditanam petani di sekitar lokasi pengkajian. Total produksi benih padi 38.5 ton kelas SS. Benih padi VUB dijual dalam bentuk kemasan dengan harga Rp. 5200/kg dan telah tersebar ke 37 desa di 0 kecamatan di Kabupaten Mandailing Natal. Dapat disimpulkan bahwa dari 3 VUB yang diamati, varietas Mekongga memberikan hasil tertinggi yaitu sebesar 8.30 t/ha gabah kering panen dibanding 2 varietas lainnya, sehingga varietas ini dapat dikembangkan untuk perbanyakan benih. Sedangkan varietas Conde dan Angke juga merupakan varietas alternatif untuk dikembangkan di lokasi pengkajian karena produksinya juga tinggi.

The application of technology innovation was conducted to overcome productivity disparity, to increase farmer income and to improve farmer prosperity. Technology innovation on rice farming has been applied at “Prima Tani” activities on intensive irrigation land since 2005 in South Sumatera Province. The aim of this study was to compare the application of technology innovation, cost production and rice farming income between participant and non participant farmers. Data of rice farming activity during wet season in 2006/2007 was collected in Mei until September 2007 by interviewing participant farmer of Prima Tani in Kertosari Village and compared the result to the non participant in Purwakarya Village, Purwodadi Sub-district, Musi Rawas Regency. Samples was taken by Disproportionate Stratified Random Sampling. Result showed that the scores of technology application from participant and non participant farmers were 6.38 and 4.37 respectively. However, there was no statistically difference between two farmers groups and included as medium category of technology application. The productivity of harvested dried rice of participant farmers was 7. 8 kg/ha and 7.2 5 kg/ha for non participant farmers. Total cost of rice farming for participant and non participant farmers were Rp.5,786,035/ha and Rp.6,663,875/ha respectively. Rice farming income of participant farmer (Rp.8,228,9 5/ha) was significantly different from those in non-participant farmer (Rp.7,235,435/ha). Key words: Paddy, farming system, innovation, income. Penerapan teknologi inovasi dilakukan untuk mengatasi masalah senjang produktivitas, meningkatkan pendapatan usahatani dan kesejahteraan petani.
