Effort to increase shallot productivity using true shallot seed (TSS) from the superior varieties supporting Proliga

Abstract

Lack of high quality/certified seed is an important constraint in shallots farming. One potential alternative technologies to be developed is the use of botanical seeds (TSS = True Shallot Seed). Stated that the cultivation of shallots using TSS is expected to cut the shallots production chain so that shallots production is stable and available throughout the year. So that the seed planted TSS can be directly used as tuber production. The assessment was done using split plot design. The main plot is two shallot varieties namely Trisula and Bima Brebes. The sub plot is four cropping systems that direct planting of seeds TSS, transplanting, planting mini bulbs, and large bulbs as a control. Parameters measured were plant growth and bulbs production, as well as input-output data. Data collected from some of the observed variables then tabulated and analyzed using SAS 9.1. software. Variety Test between treatment effect was done by using Duncan Multiple Range Test (DMRT) at the level of 95%. The results showed that the treatment by using mini tuber seeds gave the highest productivity on Trisula varieties (12.87 t / ha), followed by TSS treatment of Bima Brebes varieties with transplanting (6.78 t / ha). The results of this studied were the four applied shallot cultivation systems, the use of mini tubers as one of shallot cropping system with seeds from TSS gives the highest productivity (12.87 t / ha).
