Abstract

Good quality seeds are needed to produce potato tubers that have high quantity and quality. Seed availability needs to be supported by propagation techniques through in vitro culture. The purpose of this technical note is to provide information regarding the production stages of G0 potato seeds from in vitro cultured plantlets. Data searches were carried out from January 23 to February 24 2023 at CV. Bumi Agro Technology, Kertawangi Village, Cisarua District, Kabupaten Bandung Barat. Data was obtained from observations, field practice, discussions and interviews, as well as literature studies. The results of the data search obtained information on the production stages of G0 potato seeds, which consist of : management of plantlets originating from the IPB PPSHB Laboratory, acclimatization, transplanting, mini cuttings, land preparation, transplanting mini cuttings, maintenance including fertilizing, watering, replanting, controlling plant pest organisms, as well as harvesting and post-harvest. The results of these stages produce G0 potato seeds which are ready to be planted to produce G1 potato tubers or used as a source of explants in in vitro culture.

Abstract

This study aims to determine the performance of the yield components and the intercropping index of 22 hybrid maize in the maize-soybean intercropping system. This research was carried out in Cikajang, Garut Regency from January 2021 to June 2021. The method used in this research is a quantitative descriptive and experimental method. The experimental design used was a randomized block design with 27 treatments made in 3 replications. The genetic material used was 22 test hybrids from the Padjadjaran University collection and 5 commercial hybrids as comparisons. Assessment of yield components was carried out using The Least Significant Increase (LSI) test assessed for 4 yield components consisting of cob diameter, cob length, number of seeds cobs, and dry seed/plant weight. Intercropping index assessment was analyzed based on the calculation of Land Equivalent Ratio (LER), Area Time Equivalent Ratio (ATER), and Aggressivity (A). The results showed that there were 4 hybrids that had high yields in the maize-soybean intercropping system including DRc6 x DRc7, DRc8 X MDRc18.8.1, DRc8 X MDRc1.1.3 and MDRc3.1.4 X MDRc18.5.1. There are 3 profitable hybrids in the intercropping system of soybean maize based on the intercropping index including DRc4 X MDRc7.2.3, DRc8 x DRc9, and MDRc7.4.3 x MDRc18.8.1.
