Pests and diseases are one of the obstacles in increasing production and productivity of shallots. The study was conducted in Subak Rejasa Klod, Rejasa Village, Penebel District, Tabanan Regency - Bali Province. Research was conducted in June-November 2019, using a split plot randomized block design. The main plot is shallot varieties (V) and the subplot of the technical culture innovation (P). The main plot (V) consists of 2 treatment shallots namely Bali Karet (V1) and Lokal Tabanan (V2) and the plot consisting of 3 treatment of technical culture namely existing (P1); improvement (P2); and introduction (P3). Data on growth components and crop yields are analyzed using diversity analysis and continued with the DMRT test. Analysis of farming businesses was analyzed using B/C ratio and MBCR analysis. The results showed that Spodopthera exigua and Altenaria porri at V1 are lower than V2. The highest dry weight per hectare was obtained in the Bali Karet (V1) of 20,89 tons/ha. Introduction technology (P3) is the best innovation of dry weight-weight producing per hectare on irrigation land.. The value of B/C ratio and MBCR is 1.73 and 3.06 for introduction technology. It was concluded that introduction technology was effective as innovation of pest controllers and main diseases and were able to improve the yield of the Bali Karet variety on irrigation land.
