Agronomic performance, yield and seed production of some new superior varieties using integrated crop management approach in tabanan district, Bali province

Abstract

One of the obstacles to increasing rice productivity in paddy fields in Tabanan district is the availability of adaptive new superior varieties (NSV) with high productivity. The aim of the study was to determine the agronomic performance, yield components and seed production of three NSV lowland rice which have the potential to be developed in irrigated paddy fields at Subak Guama Tabanan districs, in collaboration with AIAT Bali as NSV seed providers. The study was conducted from February to June 2021. The study used a randomized block design (RBD) with 1 factor 4 treatments including Ciherang as a comparison and each treatment was repeated 6 times. The collected data were analyzed using analysis of variance (ANOVA), then the treatment was further tested using the Tukey test at 95%. The results of the study showed that the application with a 2:1 legowo cropping system can increase the performance and components of crop yields. The use of NSV and the 2:1 legowo planting method can increase productivity by an average of 1.24 tonnes/ha of harvested dry grain (HDG) or an increase of 19.36% tonnes/ha of HDG. The application of ICM using NSV, the legowo 2:1 planting method is one way to increase rice production.
