      Abstract
      Benih bermutu memiliki peran penting dalam keberhasilan budidaya tanaman. Mutu benih yang tercantum pada kemasan benih bersertifikat hanya kadar air benih, daya berkecambah dan kemurnian benih. Nyatanya, masih banyak peubah mutu lain yang belum tercantum salah satunya bobot 1000 butir. Penelitian ini bertujuan untuk mengetahui pengaruh perbedaan bobot 1000 butir benih terhadap viabilitas dan vigor benih, field emergence, pertumbuhan dan hasil produksi padi. Percobaan disusun dalam Rancangan Kelompok Lengkap Teracak (RKLT) dengan tiga perlakuan, yaitu benih dengan bobot 1000 butir tinggi, sedang dan rendah. Percobaan dilakukan pada tiga varietas padi, yaitu Ciherang, Inpari 32 dan Inpari 42. Bobot 1000 butir benih berpengaruh nyata pada daya hantar listrik benih, tinggi bibit, jumlah daun bibit, bobot kering bibit dan pertumbuhan tanaman padi pada ketiga varietas yang diuji. Perbedaan bobot 1000 butir benih tidak berpengaruh nyata terhadap peubah viabilitas dan vigor lainnya, indeks luas daun, umur berbunga, komponen hasil dan produksi pada ketiga varietas yang diuji. Benih dengan bobot tinggi memiliki kemampuan untuk tumbuh menjadi bibit yang kuat dan dapat mempercepat masa persemaian dari ketiga varietas yang diuji. Benih dengan rentang bobot tinggi dan sedang memiliki pertumbuhan vegetatif yang lebih baik dibandingkan dengan benih berbobot rendah.
       
      Quality seeds have an important role in the success of plant cultivation. The quality listed on the certified seed packaging is only the moisture content, germination and seed purity. In fact, there are many other quality variables that have not been listed, one of which is 1000 grain weight. This study aims to determine the effect of differences in 1000 grain weight on viability and vigor, field emergence, growth and yield. The experiment was arranged in a Completely Randomized Block Design (CRBD) with three treatments, namely high, medium and low 1000 grain weight seeds. The experiment was carried out on three rice varieties, Ciherang, Inpari 32 and Inpari 42. The 1000 grain weight significantly affected the electrical conductivity, seedling height, seedling leaves, dry weight of seeds and growth in three varieties tested. The difference in 1000 grain weight did not significantly affect on other viability and vigor variables, leaf area index, flowering age, yield and production components in three varieties tested. Seeds with high weight have the ability to grow into strong seedlings and can accelerate the seeding period of the three varieties tested. Seeds with high and medium weight ranges had better vegetative growth compared to low weight seeds.
