Abstract

Tujuan penelitian adalah mendapatkan  konsentrasi terendah Pupuk organik cair Crocober Plus (POC CP) dalam menghasilkan pertumbuhan dan hasil padi (Oryza sativa L.) yang optimal sesuai dengan iklim agroklimat setempat. Percobaan dilaksanakan sejak Oktober 2016 hingga Maret 2017 di Kelurahan Lubuk Minturun, Kecamatan Koto Tangah Padang.  Bahan yang dibutuhkan adalah padi Varietas Kabir, Pupuk buatan Urea, Zwavelzur Ammonia (ZA), SP-36 dan KCl, POC CP asal Fakultas Pertanian, ajir tonggak kayu, waring sungkup.  Percobaan disusun dalam Rancangan Acak Lengkap, dengan 6 konsentrasi pemberian Pupuk organik Cair Crocober Plus(CP) (v/v)  dengan air, yaitu; 0 ml L-1  (F0); 25 ml L-1 (F1), 50 ml L-1  (F2),  75 ml L-1 (F3), 100 ml L-1 (F4); 125 ml L-1  (F5), dan 3 ulangan. Bibit padi ditanam dengan jarak tanam 25 x 25 cm, dan ukuran  plot 2 x 2 m. Data yang diperoleh dianalisis menggunakan analysis of variance (ANOVA) taraf  nyata 5%. Jika perlakuan berpengaruh nyata dilanjutkan dengan uji BNT taraf nyata 5%. Parameter yang diamati antara lain; tinggi tanaman, jumlah anakan maksimum dan produktif, umur berbunga, panen, panjang malai, jumlah gabah per malai, bobot 1000 biji, berat gabah kering giling per hektar, persentase gabah hampa dan indek panen. Hasil percobaan membuktikan bahwa Pemberian 50 ml L-1  pupuk Organik Cair Crocober plus yang diberikan setiap 2 minggu sekali sejak 2 minggu pindah tanam hingga fase pengisian gabah mampu meningkatkan pertumbuhan dan hasil padi varietas Kabir. Hasil padi tertinggi mencapai 6,34 ton ha-1 gabah kering giling, dengan indek panen mencapai 0,53. Hasil ini masih rendah, berkisar 50% dari kemampuan padi Kabir 07 yang ditanam di Kawasan Aceh atau Jawa Tengah.

Abstract

The demand for red potatoes is quite high, especially for supermarkets and culinary businesses that require potatoes as the basic ingredient. To achieve optimal potato production, it is necessary to provide sufficient fertilizer, while the price of artificial fertilizers is getting more expensive, therefore it is necessary to look for alternative low-cost fertilizers. The purpose of the study was to find out the benefits of Trichoderma sp. fungi as liquid organic fertilizer (POC), in an effort to diminish the use of artificial fertilizers towards organic potato cultivation. The experiment was carried out from June - September 2021 at Danau Kembar. This experiment was arranged in a completely randomized design (CRD), with 2 treatment factors and 3 replications. The first factor was the administration of POC Derma (fermented inoculant Trichoderma sp) doses consisting of 5 levels, namely: 0 ml L-1 (D0), 25 ml L-1 (D1), 50 ml L-1 (D2), 75 ml L-1 (D3), 100 ml L-1 (D4). The second factor the intensity of the application consists of two levels: (I1) 1 time a week and (I2) once every 2 weeks. Observational data were analyzed by means of variance using the F-test with a significant level of 5% and if the treatment had a significant effect, it was continued with the Least Significant Difference (BNT) test with a level of 5%. From the results of experiments that have been carried out, it is found that giving POC Derma (fermented inoculant Trichoderma sp) 75 ml L-1 inevery 2 weeks gave the highest production reaching 27.56 t ha-1 in semi-organic red potato cultivation.Key words: Derma liquid organic fertilizer, Trichoderma sp, red potato, semi organic

Abstract

Iron toxicity severely constrains rice production on acidic soils by inducing nutrient imbalance and suppressing biomass accumulation. This study evaluated the effects of charged biochar and arbuscular mycorrhizal fungi (AMF) on rice growth, nutrient status, and cell wall dynamics under Fe-toxic conditions. A factorial experiment was conducted on a strongly acidic Ultisols (pH 4.63; Fe 3616.89 ppm) with AMF inoculation (0, 5, and 10%) and charged-biochar application (0, 2.5, and 5 t ha⁻¹). Both amendments significantly improved plant height, shoot dry weight, and forage dry weight (FDW), primarily through enhanced vegetative growth, nutrient-use efficiency, and root development. AMF colonization reached 68%, while charged biochar effectively ameliorated soil acidity and Fe stress. Regression analysis identified shoot dry weight, nitrogen content, ash (silica) content, and AMF colonization as the main determinants of FDW (R² = 0.996), whereas excessive plant phosphorus negatively affected yield. Cell wall components showed no direct association with FDW but contributed to tissue structural integrity. The combined application of charged biochar and AMF, supported by improved silica accumulation, provides an effective strategy to mitigate Fe toxicity and enhance rice forage productivity on acidic soils.
