      Abstract
      Penelitian ini bertujuan untuk mendapatkan informasi tentang respon varietas terhadap Zn dalam pertumbuhan, komponen hasil dan kandungan Zn dalam beras pada padi varietas IPB 3S, Akita Komachi, Hipa 18, dan Inpari 42. Penelitian dilaksanakan di Kebun Percobaan IPB Sawah Baru, Departemen Agronomi dan Hortikultura, Fakultas Pertanian, IPB pada Januari hingga Juli 2020, dilanjutkan di Laboratorium Pasca Panen, Laboratorium Uji dan Laboratorium Technopark hingga bulan Agustus 2020 Rancangan percobaan yang digunakan adalah rancangan split plot yang terdiri atas dua faktor yaitu varietas sebagai petak utama dan dosis pupuk Zn sebagai anak petak. Perlakuan varietas terdiri dari varietas IPB 3S, Akita Komachi, Hipa 18, dan Inpari 42. Perlakuan dosis Zn terdiri atas lima taraf dosis 0 kg ha-1, 4 kg ha-1, 8 kg ha-1, 12 kg ha-1 dan 16 kg ha-1. Satuan percobaan yang digunakan petakan seluas 25 m2. Hasil penelitian menunjukkan bahwa varietas memiliki karakter yang berbeda pada peubah yang diamati, meliputi seluruh peubah vegetatif, biomassa dan panen, kecuali peubah bagan warna daun lima MST, bobot basah akar dan tajuk fase vegetatif, dan volume akar fase panen. Aplikasi pupuk Zn berpengaruh nyata terhadap peubah persentase rendemen beras, beras kepala, beras pecah, dan beras menir. Perlakuan dosis pupuk Zn tidak berpengaruh terhadap pertumbuhan, hasil, komponen hasil maupun kandungan Zn dalam beras. Tidak terdapat respon yang berbeda antar varietas terhadap aplikasi dosis pupuk Zn
       
      The objective of this research was to obtain information on the effect of Zn application on growth, crop yield and Zn content in rice grain of IPB 3S, Akita Komachi, Hipa 18 and Inpari 42. The research was conducted at Sawah Baru Experimental Field, Department of Agronomy and Horticulture, IPB University from January to July 2020, and at the Post-Harvest Laboratory, Test Laboratory and Technopark Laboratory until August 2020. The experimental design used in this research was split plot design with two factors, i.e. variety as main plot and dose of Zn fertilizer as subplot. The factor of variety consisted of IPB 3S, Akita Komachi, Hipa 18, and Inpari 42. The factor of Zn fertilizer dose consisted of five levels 0 kg ha-1, 4 kg ha-1, 8 kg ha-1, 12 kg ha-1 and 16 kg ha-1. The experimental unit was a plot of 25 m2. The result showed that variety has different characteristics on vegetative variables, harvest variables, and harvest biomass variables except on leaf index color on 5 WAT, root’s and shoot’s fresh weight in vegetative phase, and root’s volume at harvest. The application of Zn fertilizer affects the variable of milled rice percentage, head rice, broken rice and rice groats percentage. Application of Zn fertilizer didn’t affect growth, yield, yield component and Zn content on rice. There are no different responses between variety on application of Zn fertilizer.
