Pengaruh Konsentrasi Biopriming dengan Trichoderma Harzianum terhadap Viabilitas dan Vigor Benih Padi

Abstrak
 Tanaman sering mengalami berbagai jenis cekaman termasuk biotik dan abiotik yang memberikan dampak buruk pada keseragaman kemunculan benih, kekuatan, dengan demikian hasil tanaman. Perlakuan biopriming diperkaya Trichoderma harzianum dapat mengurangi benih. Tujuan penelitian adalah untuk mengetahui konsentrasi pemberian larutan biopring benih padi meningkatkan viabilitas vigor padi. Penelitian menggunakan varietas Inpari 32, cendwan harzianum, molases air cucian beras. Rancangan Acak Lengkap (RAL), terdiri dari 7 perlakuan tiap masing-masing dilakukan pengulangan 3 kali. Adapun digunakan sebagai berikut: Priming (sebagai kontrol), Biopriming T 5%, 10%, 15%, 20%, 25% 30%. Hasil diperoleh bahwa 30% daya kecambah tertinggi sebesar 100%. 20% terbaik panjang akar yaitu 6,81 epikotil 5,67 cm indeks 1225,07. priming 10% keserempakan tumbuh 97,78% kecepatan 58,89%. Pemberian 10%-30% lebih baik perkecamabahan bila dibandingkan tanpa biopriming.

 ABSTRACT
 Plants are often subjected to various types of stress including biotic and abiotic which have an adverse impact on the uniformity seed emergence, thus crop yields. treatment enriched with can reduce effects seeds. The aim study was determine concentration solution rice seeds could increase viability used 32 variety, molasses washing water. a completely randomized design (CRD), consisting treatments each repeated times. were as follows: water (as control), 5% concentration, 15% results showed that gave highest germination rate best for root length, namely 6.81 epicotyl length 5.67 index 1225.07. simultaneous growth 97.78% speed 58.89%. Giving -30% better than without Keywords viability, concentration
