“…The soybean seeds were inoculated with N-fixing and Psolubilizing microbes by using a commercial product, i.e. RhiPhosAnt, to enhance initial plant growth (Hafif and Santi 2016). Bio-nano OSA was applied twice by spraying to the soil after diluting the formula 100x with fresh water at 28 and 45 day after planting (DAP).…”

“…In Lampung and northern coastal coast area of West Java, intensive dry season caused severe drought stress to the crops due to excessive evapotranspiration (Diedrich et al 2012;Christancho and Restrepo 2014). Low nutrients availability and water use efficiency were also reported as common limiting factors (Hafif and Santi 2016;Moreira and Moraes 2016). On the other hand, silica (Si) has gained more attentions where crops are able to contend drought as Si regulates stomata opening and competes to bind Al releasing P to be readily available to the crops (Farooq et al 2009;Santi et al 2017a).…”

Abstarct. Rice-field, during the dry season, offers promising potential as food crop production area particularly for secondary crops such as black soybean. However, rice-field have some limitations to support crop productivity economically, due to low fertilizer efficiency and/or water usage. Silicate (Si) fertilizer in the form of bio-nano ortho silicic acid (OSA) has been proven to improve yield and water use efficiency of black soybean on the upland, but not on rice field. This study aimed to determine the effects of bio-nano OSA application on yield, fertilizer and water use efficiencies of Detam-1 black soybean grown at a Bantarwaru rice-field, Indramayu, West Java. Experiment was undertaken from August to November 2018 with treatments consisting of : (i) control (P0), (ii) farmers’ standard practice (P1), (iii) P1 + 2 ton organic fertilizer ha-1 (P2), (iv) 50% P1 + 4 L bio-nano OSA ha-1 (P3), (v) 75% P1 + 4 L bio-nano OSA ha-1 (P4), and (vi) P1 + 4 L bio-nano OSA ha-1 (P5), in a randomized block design with three replications. The soil belongs to Alfisols with vertic property, i.e. cracking during the dry season. The results show that the application of bio-nano OSA was capable of improving yield of Detam-1 black soybean up to 26%, increasing water use efficiency up to 37%, and reducing NPK fertilizer dosages up to 50%. The highest yields of Detam-1 black soybean was 2.4-2.5-ton bean ha-1, achieved from the treatment of combination of 50-75% NPK fertilizer dosages and application of bio-nano OSA at 4 L ha-1 rate with optimum level of NPK dosage at 39.2%. By using bio-nano OSA and optimum dosage of NPK fertilizer, the farmer’s profit increased IDR 4,152,340 ha-1 per season compared to standard practice.Abstrak. Sawah tadah hujan pada musim kemarau menawarkan peluang yang prospektif untuk dimanfaatkan sebagai areal produksi tanaman pangan khususnya palawija seperti kedelai hitam. Namun, sawah tadah hujan secara umum memiliki masalah khusus untuk mendukung produktivitas tanaman di musim kemarau yaitu rendahnya efisiensi serapan hara dan/atau penggunaan air. Teknologi pupuk silika dalam formulasi bio-nano ortho-silicic acid (OSA) telah terbukti mampu meningkatkan hasil kedelai hitam dan efisiensi penggunaan air pada lahan tegalan tetapi tidak pada lahan sawah tadah hujan. Penelitian ini ditujukan untuk mempelajari pengaruh aplikasi pupuk Si (bio-nano OSA) terhadap produksi tanaman kedelai hitam Detam-1, efisiensi penggunaan pupuk, dan air pada sawah tadah hujan di Bantarwaru, Indramayu, Jawa Barat. Percobaan dilaksanakan di lahan petani pada bulan Agustus hingga Nopember 2018 dengan menguji perlakuan : (i) kontrol (P0), (ii) pemupukan standar petani (P1), (iii) P1 + 2 ton pupuk organik ha-1 (P2), (iv) 50% P1 + 4 L bio-nano OSA ha-1 (P3), (v) 75% P1 + 4 L bio-nano OSA ha-1 (P4), dan (vi) 100% P1 + 4 L bio-nano OSA ha-1 (P5), dalam rancangan acak kelompok dengan ulangan tiga kali. Tanah di lokasi percobaan tergolong ordo Alfisol dengan sifat vertik seperti timbulnya retakan saat musim kemarau. Hasil percobaan menunjukkan bahwa aplikasi bio-nano OSA mampu meningkatkan produksi kedelai hitam varietas Detam-1 hingga 26%, meningkatkan efisiensi penggunaan air hingga 37%, dan menghemat dosis pupuk NPK hingga 50%. Produktivitas kedelai hitam tertinggi sebesar 2,4–2,5 ton biji kering ha-1 diperoleh pada perlakuan kombinasi pupuk NPK 50-75% dari standar petani dan aplikasi bio-nano OSA 4 L ha-1 dengan dosis optimum pupuk NPK pada 39,2%. Tambahan keuntungan usaha tani kedelai hitam Detam-1 di Bantarwaru dengan aplikasi bio-nano OSA dan pemupukan NPK yang optimum dapat mencapai IDR. 4.152.340 ha-1 per musim jika dibandingkan perlakuan dosis pupuk standar.

“…Kondisi ini berpengaruh negatif terhadap pertumbuhan dan hasil kedelai, bergantung pada varietas yang ditanam, lama genangan, dan fase pertumbuhan (Morita et al 2004;Rhine et al 2010;Kuswantoro 2011). Tanah yang jenuh air atau tergenang hingga 5 cm di atas permukaan lahan tidak masalah bagi kedelai, asal periode genangan tidak lebih dari 5 hari, tanaman sudah melewati fase perkecambahan, dan belum memasuki fase generatif (Indradewa et al 2004;Ghulamahdi et al 2009;Ghulamahdi et al 2016;Hafif dan Santi 2016). Hal ini menunjukkan pengaruh buruk kondisi air pada LPS dapat diminimalisasi dengan pengelolaan yang baik, waktu tanam yang tepat agar tanaman terhindar dari banjir, dan penggunaan varietas yang adaptif.…”

Indonesia has large swamplands that could be developed into agricultural land for food crops. The physico-chemical characters of the soil in this agroecology, however, are generally unfavorable for the crop growth. Soybean yield of more than 2.0 t/ha might be achieved by implementing a suitable cultural practice. The objective of the current research was to evaluate the effectiveness, technical as well as financial feasibilities of improved soybean cultural practice (Kepas technology) on swampland. The research was conducted on swampland, in Jambi and South Kalimantan Provinces in 2018 on an area of 40 ha and 11 ha, respectively. The main components of the Kepas technology consisted of Anjasmoro improved variety, drainage canal on every 2.5 m or 3 m, soil amelioration using 750 kg/ha dolomite plus 1 t/ha organic fertilizer, and inorganic fertilization of 150 kg/ha Phonska and 100 kg/ha SP36. Results showed that practicing of such technology was effective to increase soybean grain yield on swampland, achieving an average of 2.3 t/ha in Jambi and 1.9 t/ha in South Kalimantan. The Kepas technology was technically and financially considered feasible, with the R/C ratio of 2.02 and 1.46, and the B/C ratio of 1.02 and 0.46 in Jambi and South Kalimantan, respectively. Break even points (BEP) of applying Kepas technology was Rp 4,445 per kg of grain at a yield of 1.14 t/ha and Rp 5,818 per kg of grain at a yield of 1.30 t/ha in Jambi and South Kalimantan, respectively.
