Efficient mechanized rice transplanting depends on both the structural integrity of seedling mats and the physiological quality of the seedlings. To address this need, enhancing seedling and mat through organic growing media is essential for optimizing mechanized rice transplanting. This study aimed to evaluate the effects of organic amendments on seedling quality (seedling height, biomass, and plant population) and mat characteristics (thickness, weight, rolling score and diameter) in tray nursery. A randomized complete block design with three replications was employed, testing four treatments: alluvial soil without organic amendment (CO), with vermicompost (V), with rice husk ash (R), and with vermicompost and rice husk ash (RV). The results showed that the rice seedling nursery using a mixture of soil and organic growing media (R, RV, and V) produced better seedling quality compared to CO including seedling height, biomass, and plant population. Regarding mat performance, RV produced the thickest (1.77 cm) and lightest (3.27 kg) mats, aligning with ideal conditions for mechanical transplanting. In contrast, CO mats were the heaviest (4.40 kg), and V produced the thinnest mats (1.40 cm). Rolling quality was highest in CO (score 10), while RV mats showed lower rolling integrity (score 6.7). V treatment achieved the smallest roll diameter (13.87 cm), facilitating better handling and transport. Overall, the results demonstrate that organic amendment selection significantly affects both physiological seedling traits and the physical integrity of seedling mats. The RV treatment offered the most balanced improvement in mat structure and seedling growth, making it a promising option for mechanized rice production.

Conclusion

This study demonstrates that rice seedling quality and the physical and structural properties of seedling mats are significantly influenced by the type of organic growing media applied during the nursery phase.The RV treatment produced optimal growth and lighter mats, making them highly suitable for mechanical transplanting.The findings highlight the importance of balancing mechanical suitability with agronomic performance when selecting organic amendments for rice seedling production.

Future Research

Penelitian lebih lanjut perlu dilakukan untuk mengkaji pengaruh kombinasi berbagai jenis bahan organik lainnya, seperti kompos jerami atau pupuk hijau, terhadap kualitas semai padi dan karakteristik mat. Studi ini dapat dilakukan dengan menguji berbagai proporsi campuran bahan organik untuk menemukan formulasi optimal yang sesuai dengan kondisi tanah dan iklim setempat. Selain itu, penelitian perlu difokuskan pada analisis mendalam terhadap perubahan sifat fisikokimia tanah akibat aplikasi bahan organik, termasuk kandungan unsur hara, struktur tanah, dan aktivitas mikroorganisme tanah. Pemahaman yang lebih baik tentang mekanisme peningkatan kualitas semai dan mat melalui perubahan sifat tanah akan membantu mengembangkan strategi pengelolaan yang lebih efektif dan berkelanjutan. Terakhir, penelitian lanjutan perlu mengevaluasi kinerja semai padi yang dihasilkan dari berbagai perlakuan bahan organik setelah ditransplantasikan ke lahan sawah, termasuk pertumbuhan tanaman, hasil panen, dan ketahanan terhadap hama dan penyakit. Evaluasi ini akan memberikan gambaran yang komprehensif tentang manfaat jangka panjang dari penggunaan bahan organik dalam produksi padi.
