Evaluasi Produktivitas Beberapa Varietas Padi

Abstract

The research was conducted during February to June 2014 in Muara Rice Research Institute, Bogor. The purpose of this study was to determine the factors that affect the productivity of some rices varieties The design used was a randomized complete design group with one factor consists of 6 varieties. The varieties used were high yielding varieties (Inpari 13, Ciherang, Mekongga), a new plant type of rice (IPB 4S), local variety (Mentik Wangi), and hybrid variety (Hipa Jatim 2). Each variety was replicated of three. The results showed that in general, high yielding varieties (VUB) Inpari 13, Ciherang and Mekongga have higher productivity than other varieties (local, PTB, hybrid). VUB Productivity ranged from 4.59 to 5.62 tons per hectare. The results of the three VUB productivity was influenced by yield components such as number of productive tillers, 1000 grain weight, percentage of filled grain and resistance to pests and diseases.
