Abstract

Indonensian Agency for Agricultural Research and Development (IAARD) has issued some fertilization recommendations, such as fertilization based on Soil Test Kit for Low Land Rice (PUTS) and Planting Calendar (PC). The reasearch aimed to introduce and examine the effects of various fertilizer recommendations, especially on low land. The research was conducted in Lubuk Sakti village, Indralaya sub-district, Ogan Ilir district from April to Agustus 2013. The research was arranged in 3 treatments fertilization based on PUTS,  PC and farmer practice (control). The rice varieties used Inpari 12. Legowo plating system was applied by 4:1 (plant spacing 25 x 50 x 12.5 cm) and farmers practice (plant spacing 25 x 25 cm). The plot size was 13 m x 27.5 m. The results showed that both of fertilizer recommendations issued by IAARD were able to increase rice productivity than control.  STK, PC and control with the yield 5.60 t/ha, 6.56 t/ha and 5,20 t/ha, respectively. Fertilizer recommendations also reduced rice pests and diseases.

Abstract

The Effectiveness of Fertilizer Recommendations Package on Rice Productivity in Freshwater Land of Ogan Ilir, South Sumatera. Indonesian Agency for Agricultural Research and Development, Ministry of Agriculture has issued fertilizer recommendation package based on soil test kit for lowland rice (PUTS) and integrated cropping calendar (KATAM). Crop growth and yield of rice in freshwater land is mostly affected by rice varieties and fertilizer application due to variation in soil conditions. The study aim was to determine the effects of both fertilizer technologies on growth and yield as well as suppression of pest attacks of three rice varieties in lowland swampy areas of South Sumatera. The experiment was conducted in Lubuk Sakti village Ogan Ilir, South Sumatera from April to August 2013. It was arranged in a completely randomized design (CRD) with seven technology packages consisted of three rice varieties (Inpari 10, Inpari 12, Inpari 14) and two fertilizer technologies. Legowo 4:1 type 1 was applied for all treatments except for farmer’s technology where transplanting spacing was 20x20 cm. The results showed that combination between fertilizer recommendation package and rice variety gave significant effect on plant growth, yield and pest attack of rice crop. Fertilizer recommendation fromKATAM combined with Inpari 12 rice variety gave the highest productivity at 8,2 t grain/ha. The technology package of PUTS showed better effect on suppressing the intensity of counterfeit white pest and blast diseases upto 55.8% and 68% respectively. Keywords: Fertilization, freshwater land, riceABSTRAKBadan Penelitian dan Pengembangan Pertanian telah menghasilkan rekomendasi teknologi pemupukan berdasarkan Perangkat Uji Tanah Sawah (PUTS) dan Kalender Tanam (KATAM) Terpadu. Pertumbuhan dan hasil tanaman padi di lahan rawa lebak sangat dipengaruhi oleh varietas padi dan pemupukan mengingat karakteristik tanahnya beragam. Penelitian bertujuan mengetahui pengaruh rekomendasi paket pemupukan terhadap pertumbuhan, produktivitas serta penekanan serangan hama penyakit tiga varietas padi di lahan lebak SumateraSelatan. Penelitian dilaksanakan di Desa Lubuk Sakti, Kecamatan Indralaya Kabupaten Ogan Ilir dari April hingga Agustus 2013. Penelitian menggunakan Rancangan Acak Lengkap dengan tujuh perlakuan kombinasi antara varietas (Inpari 10, Inpari 12, Inpari 14) dan dosis pemupukan (PUTS dan KATAM Terpadu), sehingga diperoleh paket: Inpari 10 PUTS, Inpari 10 KATAM, Inpari 12 PUTS, Inpari 12 KATAM, Inpari 14 PUTS, Inpari 14 KATAM dan Inpari 12 Cara Petani. Penanaman dilakukan dengan sistem tanam tegel (20 cm x 20 cm) untuk cara petani, dan sistem tanam jajar legowo 4:1 tipe 1 untuk perlakuan rekomendasi pemupukan PUTS dan KATAM.Hasil penelitian menunjukkan bahwa kombinasi rekomendasi pemupukan dan varietas padi berpengaruh nyata terhadap pertumbuhan dan hasil serta tingkat serangan hama dan penyakit tanaman. Rekomendasi pemupukan KATAM pada varietas Inpari 12 memberikan produktivitas tertinggi, yaitu 8,2 t GKG/ha. Sedangkan paket rekomendasi pemupukan PUTS mampu menekan intensitas serangan hama putih palsu dan penyakit blas lebih tinggi, yaitu masing-masing 55,8% dan 68%.Kata kunci: Padi, pemupukan, rawa lebak

Abstract

Varietas unggul memberikan kontribusi nyata terhadap peningkatan produksi padi. Sumbangan penggunaan varietas unggul terhadap peningkatan produksi padi nasional mencapai 56%, sementara interaksi antara air irigasi, varietas unggul, dan pemupukan terhadap laju kenaikan produksi padi memberikan kontribusi hingga 75%. Penggunaan varietas unggul juga berkontribusi terhadap penurunan penggunaan pestisida. Namun, penggunaan varietas unggul di tingkat petani masih rendah. Beberapa faktor yang menghambat pengembangan varietas unggul ialah anggapan bahwa keunggulan varietas baru tidak sebanding dengan varietas yang ada, industri benih belum berminat mengembangkan varietas unggul, dan terbatasnya benih sumber untuk perbanyakan benih secara komersial. Tingkat komersialisasi varietas unggul dipengaruhi oleh produktivitas, kesesuaian mutu produk dengan selera konsumen, ketahanan terhadap hama dan penyakit, serta harga jual. Untuk mendukung percepatan adopsi varietas unggul padi, perlu kebijakan dalam bentuk peraturan daerah peningkatan produksi padi, jaminan sumber permodalan, penyediaan input terutama benih sumber, jaminan pemasaran dan harga jual gabah, kemitraan yang harmonis antarpemangku kepentingan, penguatan yang menarik hubungan dengan sumber informasi teknologi dan pasar output, reformasi, reorientasi dan revitalisasi kelembagaan petani, penguatan kelembagaan penyuluhan, serta pendekatan kepada tokohmasyarakat.

Abstract

Somantri et al, 2019. Potential of Several Soybean Varieties in Dry Land of South Sumatera. pp. 473-481. Soybean productivity is determined by climate, land suitability also innovations applied such as the use of superior varieties.  Soybean cropping areas mostly covers ricefield and dry land in South Sumatera, in where rice field fertility is better than dry land.  With total of 364.583 Ha dry land, soybean cultivation is potential to be developed in South Sumatera to obtain self-sufficiency and minimize soybean imports.  The activity was carried out in Talang Ubi Sub-district in Penukal Abab Lematang Ilir (PALI) District in 2018.  The study was aimed to understand the growth and yield of some adaptive soybean superior varieties (VUB) in dry land of South Sumatera.  Technologies applied was the use of several soybean VUB i.e. Burangrang, Dering 1. Demas 1 dan Anjasmoro, fertilizer based on Dry Land Test Kit (PUTK), the use of manual grains seeder (ATBJ), Rhizobium application on seeds and integrated pest control. The result showed that the highest yield was obtained from Dering 1 for 2,3 t/ha of dry seed and the lowest was Burangrang for 1,36 t/ha.
