| dc.description.abstract | Jagung manis (Zea mays L. Saccharata) merupakan komoditas hortikultura yang memiliki nilai ekonomi tinggi, namun produktivitasnya sering terkendala oleh rendahnya kesuburan tanah dan rendahnya efisiensi pemupukan. Penggunaan pupuk hayati majemuk menjadi salah satu alternatif untuk meningkatkan efisiensi pemanfaatan hara sekaligus mendukung sistem budidaya yang lebih berkelanjutan. Penelitian ini bertujuan untuk mengetahui efektivitas pupuk hayati majemuk terhadap pertumbuhan dan produktivitas jagung manis. Penelitian dilaksanakan pada bulan Juli sampai Oktober 2025 di Indonesian Center for Biodiversity and Biotechnology (ICBB), Bogor, menggunakan rancangan acak kelompok dengan lima perlakuan dan lima ulangan, yaitu kontrol tanpa pupuk, 100% NPK standar, 100% NPK + pupuk hayati majemuk, 75% NPK + pupuk hayati majemuk, dan 50% NPK + pupuk hayati majemuk. Parameter yang diamati meliputi tinggi tanaman, jumlah daun, diameter batang, komponen hasil, dan Efektivitas Agronomi Relatif (EAR). Hasil penelitian menunjukkan bahwa aplikasi pupuk hayati majemuk berpengaruh nyata terhadap pertumbuhan dan produktivitas jagung manis. Perlakuan 75% NPK + pupuk hayati majemuk memberikan respons terbaik pada sebagian besar parameter pengamatan serta menghasilkan nilai EAR tertinggi sebesar 233%. Pupuk hayati majemuk terbukti efektif dalam meningkatkan pertumbuhan dan produktivitas jagung manis melalui peningkatan efisiensi pemanfaatan hara dan aktivitas biologis tanah, sehingga penggunaan pupuk anorganik dapat dikurangi tanpa menurunkan produktivitas tanaman. | |
| dc.description.abstract | Sweet corn (Zea mays L. Saccharata) is a horticultural commodity with high economic value; however, its productivity is often constrained by low soil fertility and low fertilization efficiency. The use of compound biofertilizer is one alternative to improve nutrient use efficiency while supporting a more sustainable cultivation system. This study aimed to determine the effectiveness of compound biofertilizer on the growth and productivity of sweet corn. The research was conducted from July to October 2025 at the Indonesian Center for Biodiversity and Biotechnology (ICBB), Bogor, using a randomized block design with five treatments and five replications, namely: control without fertilizer, 100% standard NPK, 100% NPK + compound biofertilizer, 75% NPK + compound biofertilizer, and 50% NPK + compound biofertilizer. The parameters observed included plant height, number of leaves, stem diameter, yield components, and Efektivitas Agronomi Relatif (EAR). The results showed that the application of compound biofertilizer had a significant effect on the growth and productivity of sweet corn. The 75% NPK + compound biofertilizer treatment gave the best response for most of the observed parameters and produced the highest EAR value of 233%. Compound biofertilizer proved effective in enhancing the growth and productivity of sweet corn by improving nutrient use efficiency and soil biological activity, thereby allowing a reduction in inorganic fertilizer use without decreasing plant productivity. | |
