Abstract

Abstract The low rice productivity in Lampung needs to be increased. The objectives of this study were to introduce new superior Inpari IR Nutri Zinc rice and determine the effect of planting systems and biofertilizer on the growth and yield of Inpari IR Nutri Zinc rice in technically irrigated rice fields in Lampung. The experiment was carried out in technically irrigated rice fields in Kalirejo Village, Negeri Katon District, Pesawaran Regency, Lampung Province, using a split-plot design in a randomized block design with three replications. The treatments tested were three rice planting systems as the main plot and the dose of biofertilizer as a sub-plot. The parameters observed components of growth and yield components. Data were analyzed with the SAS software 5.4 version. The results showed that the application of biofertilizers gave effects on rice yield. From the results of this study, it can be concluded that the use of biofertilizers can increase rice yields by 10-12% compared to those without biofertilizers, in the three cropping systems. The application of biofertilizers resulted in the highest harvested dry grain production, namely 6.61 tons per hectare and significantly different than that without biofertilizers, namely 5.96 tons per hectare. The production of dry grain harvested by the three cropping systems was not significantly different at an average of 6.28 tons per hectare.
