However, the use of manure requires a long time and a relatively large amount to have a positive impact on the soil and plants. In this regard, a study was carried out to evaluate the effect of the application of organic fertilizer and NPK inorganic fertilizer on soybean in lowland Vertisol. The study was conducted in lowland Vertisols in Ngawi and Madiun. The experiment used a randomized block design with three replications, with combination treatments of cow and chicken manure, Santap NM1 and NM2 fertilizer, and Phonska. The soybean seed used in this research was Local Central Java/Sinabung-1036 soybean line. The results showed that in lowland Vertisol of Ngawi which is rich in P element, application of 5,000 kg of cow manure/ha, 3,000 kg of chicken manure/ha, 1,500-2,500 kg/ha Santap NM1 and NM2 fertilizers, and 300 kg of Phonska/ha is not required. The yield of Local Central Java/Sinabung-1036 soybean line reached 1.95 t/ha. The lowland Vertisol of Madiun which has poor P element requires the addition of 5,000 kg of cow manure/ha, 1,500-2,500 kg/ha of Santap NM2 fertilizer, and 150 kg of Phonska/ha to increase soybean yield by 21-27% (0.42-0.55 t/ha). The quality and productivity of soil and crop cultivation in sustainable agriculture can be maintained by alternative recommendations for the use of organic and inorganic fertilizer inputs.

Short Communication: Effect of organic and inorganic fertilizers application on the early-medium maturing soybean yield. Nusantara Bioscience 10: 1-5. Efforts to increase soybean productivity can be made with the application of organic and inorganic fertilizers. Large amounts of organic fertilizer are required to give a positive impact on soybean yield. However, this practice is deemed inefficient in terms procurement and transportation, making farmers less interested. The addition of inorganic fertilizer or the use of nutrient-rich organic fertilizer (Santap NM2) is among the solutions. The objective of this research was to formulate management techniques for organic and inorganic fertilizers application on the early-medium maturing soybean line, Lokal Jateng/Sinabung-1036, to achieve the soybean’s maximum potential yield. The research was conducted on Alfisols at Muneng Research Station, Probolinggo, and Vertisols at Ngale Research Sta...

Identifikasi teknologi budidaya yang sesuai perlu dilakukan guna meningkatkan produksi. Tujuan penelitian adalah untuk mendapatkan kombinasi varietas dan pupuk yang efektif guna meningkatkan produktivitas kacang hijau pada tanah masam. Penelitian dilaksanakan di rumah kasa Balai Penelitian Tanaman Aneka Kacang dan Umbi (Balitkabi), Malang, Jawa Timur mulai bulan November 2014 hingga Januari 2015. Penelitian terdiri atas dua faktor yang disusun dalam Rancangan Petak Terpisah, diulang tiga kali. Petak utama adalah empat macam varietas kacang hijau: Kenari (V1), Murai (V2), Kutilang (V3), dan Vima 1 (V4). Anak petak adalah lima macam pemupukan: tanpa pemupukan (P0), Phonska 300 kg/ha (P1), pupuk kandang sapi 1,5 t/ha (P2), pupuk kandang sapi 3 t/ha (P3), dan pupuk kandang sapi 5 t/ha (P4). Hasil penelitian menunjukkan bahwa penggunaan varietas Kenari, Murai, Kutilang dan Vima 1 mempunyai daya adaptasi yang sama pada tanah masam asal Banten. Hasil biji varietasvarietas tersebut dapat ditingkatkan dengan pemupukan 300 kg/ha Phonska atau dengan pupuk kandang sapi dosis 3 t/ha.
