The study aimed to determine the best of nitrogen fertilizer level based on growth and biomass production of brown midrib sorghum mutant line Patir 3.7. This research was conducted at the Field Laboratory in the Faculty of Animal Science, Andalas University, Padang. The experiment was assigned in a completely randomized block design with 4 levels of nitrogen fertilizer application and 3 replications. The treatments consisted of N0= 0 kg N ha-1 as a control; N1= 50 kg N ha-1 ; N2= 100 kg N ha-1 ; and N3= 150 kg N ha-1. Agronomic and production variables measured were plant height, stem diameter, leaf width length, leaf stem panicle ratio, stem Brix sugar content, as well as fresh biomass and nutrient production. Analysis of variance followed by Duncan Multiple Range Test (DMRT) was conducted. The results showed that the addition of nitrogen fertilizer produced the highest stem diameter, leaf length, leaf width, leaf ratio, and stem ratio (p<0.05). However, the panicle ratio and stem Brix sugar contents were not significantly affected (p>0.05) by the level of nitrogen fertilizer. The fresh biomass, dry matter, crude protein, ash, NFE, and TDN production increased significantly (p<0.05) with the increased level of nitrogen fertilizer. Based on those findings, it can be concluded that nitrogen fertilizer application at the level of 50 kg N ha-1 produces better growth, fresh biomass, dry matter, and nutrients production.

“…Keuntungan penanaman jagung di antara tanaman karet antara lain: 1) kebun karet terpelihara dari pertumbuhan gulma (Ar-riza et al 2001;Rosyid 2007;George et al 2007;Sari dan Rahayau 2013;Novalinda et al 2014); 2) pertumbuhan lilit batang karet lebih baik daripada menggunakan kacangan penutup tanah (Rodrigo et al 1995;Wibawa dan Rosyid 1995;Weifu et al 1999;Wibawa 2000;Rodrigo 2001;Rodrigo et al 2001;Jose 2002;Pathiratna 2006;Carlito et al 2007;Rosyid et al 2012;Sahuri 2017b;Sahuri 2017c); 3) produksi karet meningkat (Anikumar et al 2005;Anwar 2006;Esekhade et al 2007); 4) bahan organik tanah meningkat (Rodrigo et al 2004;Raintree 2005;Pathiratna dan Perera 2006;Snoeck et al 2013;Sahuri dan Rosyid 2015); dan 5) pendapatan petani meningkat dan dapat menyediakan kebutuhan pangan sendiri (Prukwiwat 2005;Joshi et al 2007;Kheowvonsri 2007;Ogwuche et al 2012;Sahuri dan Rosyid 2015;Pansak 2015;Sahuri 2017a).…”

“…Berdasarkan hasil analisis tanah pada Tabel 2 menunjukkan bahwa pola tumpang sari jagung di antara tanaman karet nyata meningkatkan variabel tanah yang diuji dibandingkan dengan pola karet monokultur. Hal ini sesuai dengan hasil penelitian Rodrigo et al (2004); Raintree (2005); Pathiratna dan Perera (2006); Rosyid (2012); Snoeck et al (2013); Sahuri dan Rosyid (2015); dan Sahuri (2017b). Sisa-sisa panen jagung diaplikasikan kembali ke lahan karet sebagai bahan organik sehingga berpengaruh nyata terhadap peningkatan kandungan bahan organik tanah di antara tanaman karet (Tabel 2).…”

“…Selain itu, secara umum petani menanam tanaman karet pada lahan kering masam podsolik merah kuning sehingga kendala pengusahaan jagung sebagai tanaman sela karet antara lain: lahan kering masam (pH 4,0-5,0), kandungan aluminium (Al) tinggi (kejenuhan Al > 50%), kandungan bahan organik rendah (< 3%), dan ketersediaan hara rendah (Wijaya 2008;Sahuri 2017bSahuri , 2017c. Faktor pembatas di lahan kering adalah rendahnya bahan organik, pH tanah, kalium (K) dan fosfor (P) tersedia (Marwoto et al 2008;Kuntyastuti dan Taufiq 2008).…”

Land between juvenile rubber rows in the rubber plantation is potential for corn farming. This research aimed to assess corn production and added value of corn farming intercropped with juvenile rubber. It also studied effect of corn intercrop on land productivity improvement and juvenile rubber growth. The experiment was conducted at the Sembawa Research Station from January until April 2016 on the juvenile rubber plantation using IRR 112 clone and spacing of 6 m x 3 m (550 tree per ha). The experiment was carried using a randomized block design (RBCD) with treatments of two planting-patterns, i.e. PT1 (rubber+corn) and PT2 (monoculture corn) with three replications, and the control was monoculture corn. The data were analyzed using ANOVA followed by DMRT at the level of 5%. Results of the research showed that corn intercropped with rubber significantly affected land productivity and IRR 112 clone growth during juvenile rubber period. Intercropped corn farm business in the juvenile rubber plantation was profitable as its R/C ratio of 1.62 at corn lower price and R/C ratio of 2.27 at corn higher price. Intercropped corn farming was profitable and it was feasible practiced inside the juvenile rubber plantation. AbstrakLahan di antara tanaman karet belum menghasilkan (TBM) berpotensi untuk dimanfaatkan guna mengembangkan tanaman jagung. Penelitian bertujuan mengetahui produksi jagung serta nilai tambah usaha tani jagung sebagai tanaman sela dan mengetahui pengaruh tanaman sela jagung terhadap peningkatan produktivitas lahan karet dan pertumbuhan lilit batang karet. Penelitian ini dilaksanakan di Kebun Percobaan Balai Penelitian Sembawa, kebun karet TBM klon IRR 112, jarak tanam 6 m x 3 m (550 pohon/ha), dimulai dari bulan Januari sampai April tahun 2016. Penelitian menggunakan rancangan acak kelompok (RAK), terdiri dari dua pola tanam yaitu: PT1 (karet+jagung) dan PT2 (karet monokultur), diulang tiga kali dan sebagai pembanding adalah jagung monokultur. Data dianalisis dengan sidik ragam, jika berbeda nyata diuji lanjut DMRT pada taraf 5%. Hasil penelitian menunjukkan bahwa tanaman jagung sebagai tanaman sela karet berpengaruh nyata terhadap peningkatan produktivitas lahan karet dan pertumbuhan tanaman karet klon IRR 112 pada masa TBM. Usaha tani jagung sebagai tanaman sela karet pada saat harga rendah masih menguntungkan dengan R/C ratio 1,62, sedangkan pada saat harga tinggi sangat menguntungkan dengan R/C ratio 2,27. Secara ekonomi usaha tani jagung menguntungkan dan layak untuk dikembangkan sebagai tanaman sela karet pada masa TBM.

“…Persyaratan iklim ini kurang lebih sesuai dengan keadaan iklim di daerah Sumatera Selatan, kecuali adanya musim kemarau dan distribusi curah hujan yang tidak merata sepanjang tahun di Sumatera Selatan. Sumatera Selatan mempunyai curah hujan tahunan di atas 2.000 mm/tahun dengan bulan kering (<100 mm/bulan) berjumlah 34 bulan berturut-turut (Wijaya 2008;Sahuri 2017). Menurut (Wijaya et al 1994;Wijaya et al 1996;Wijaya 1996;Watson 1989;Hidayati & Wijaya 2003;Wijaya 2008), daerah dengan curah hujan 1.5003.000 mm/tahun, bulan kering sebanyak 34 bulan berturut-turut, serta suhu udara berkisar Balai Penelitian Sembawa, Jl Raya Palembang-Pangkalan Balai Km.…”

ABSTRAK Secara umum produksi karet dipengaruhi oleh fluktuasi curah hujan setiap bulan. Penelitian bertujuan mengetahui pengaruh curah hujan, evapotranspirasi, dan ketersediaan air lahan terhadap produksi karet klon PB260. Penelitian ini dilaksanakan di Kebun Percobaan Balai Penelitian Sembawa, Sumatera Selatan pada tahun 20132016. Plot penelitian yang digunakan adalah tanaman menghasilkan klon PB260 tahun tanam 2002 dengan tekstur tanah clay loam. Penelitian ini dilakukan dengan cara membandingkan produksi tanaman karet pada saat musim hujan dan kemarau dari tahun 20132016. Hasil penelitian menunjukkan bahwa kadar air tanah merupakan parameter yang paling berpengaruh terhadap hasil lateks tanaman karet klon PB260 dibandingkan dengan parameter curah hujan dan evapotranspirasi. Hasil lateks menurun dengan berkurangnya kandungan air tanah pada periode bulan kering. Kurangnya air pada bulan kering menjadi faktor pembatas untuk hasil karet yang optimal. Ketika kadar air tanah turun hingga di bawah 100 mm, hasil lateks maksimal yang dapat dicapai oleh tanaman karet adalah sebesar 18 g/p/s. Kata kunci: kandungan air tanah, klon PB260, neraca air lahan, produksi karet ABSTRACT In general, rubber production was influenced by fluctuation of monthly rainfall rate. This research was aimed to determine the effect of rainfall, evapotranspiration, and soil water content on the production of PB260 rubber clone. This research was conducted at Sembawa Research Centre Experimental Field, South Sumatera from the year 20132016. The observed rubber tree was mature PB260 clone planted on clay loam soil. Rubber productions on the dry and rainy season on 20132016 were compared to determine the effect of rainfall on rubber production. The results showed that soil water content has the closest relationship to rubber production compared to rainfall and evapotranspiration parameter. Latex yield was decreasing as the decrease of soil water content at dry season. Limited water during the dry season became a constraint of optimum rubber yield. When soil water content drops below 100 mm, the maximum attained latex yield was 18 g/t/t.
