Selada, , Pembibitan, , Trichoderma sp., , Pupuk hayatiAbstract
Selada (Lactuca sativa L.) merupakan salah satu komoditas hortikultura yang memerlukan bibit berkualitas untuk menghasilkan pertumbuhan tanaman yang optimal. Salah satu alternatif yang dapat digunakan untuk meningkatkan kualitas bibit adalah aplikasi Trichoderma sp. sebagai fungi pemacu pertumbuhan tanaman yang mampu meningkatkan ketersediaan unsur hara, menghasilkan fitohormon, dan memperbaiki perkembangan sistem perakaran. Penelitian ini bertujuan untuk mengetahui pengaruh aplikasi Trichoderma sp. terhadap pertumbuhan bibit tanaman selada yang diberi naungan. Penelitian dilaksanakan di Kabupaten Purwakarta. Menggunakan Rancangan Acak Kelompok (RAK) dengan empat perlakuan, yaitu T0 (kontrol), T1 (40 g/polybag), T2 (60 g/polybag), dan T3 (80 g/polybag), yang diulang tiga kali. Parameter yang diamati meliputi tinggi tanaman dan jumlah daun pada umur 7 dan 14 Hari Setelah Tanam (HST), serta panjang akar pada umur 14 HST. Hasil penelitian menunjukkan bahwa perlakuan Trichoderma sp. menunjukkan kecenderungan pertumbuhan yang lebih baik dibandingkan kontrol, ditunjukkan oleh tinggi tanaman tertinggi pada perlakuan T2 sebesar 7,00 cm dibandingkan kontrol 5,00 cm, jumlah daun tertinggi pada perlakuan T1 sebesar 14,75 helai dibandingkan kontrol 11,25 helai, serta panjang akar tertinggi pada perlakuan T3 sebesar 7,25 cm dibandingkan kontrol 4,50 cm.
