Lampung is one of the centers for shallot development in Indonesia. The application of location-specific off-season shallot cultivation technology and the use of superior varieties is expected to be able to guarantee its availability throughout the year and overcome price fluctuations. For this reason, it is necessary to study the cultivation of off-season shallots with varieties in accordance with market demand. This activity was carried out in Tanggamus Regency, from January to December 2018. The experimental design was the Split Plot, where the main plot was the use of mulch and without mulch and as sub-plots were three shallot varieties, namely: 1. Bima Brebes; 2. Trisula; and 3. Bali Karet varieties. Each treatment was repeated four times. The data obtained were analyzed using variance with DMRT at the 5% level. The results of the study show that off-season shallot cultivation is promising to be cultivated by farmers with an average of 14.59 tonnes/ha using Bima Brebes, Trisula, and Bali Karet varieties. Bali Karet variety has good prospects to be developed and planted off-season because they are more resistant to pests and diseases and have the highest production (20.87 tonnes/ha) compared to Bima Brebes and Trisula varieties.

The resistance of some_introduced hybrid genotypes maize (Zea mays) towards insect pests. Plant resistance to insect pest play an important role in integrated pest management. Fourty hybrid genotypes released by CIMMYT Mexico and two National hybrid varieties (Pioner 13 and Andalas) as local control had been tested threir resistance to insect pests. The trial was conducted at Natar Station Experimental, South Lampung from April to July 2002. The objective of the experiment was to obtaine the hybrid genotypes in which have a good tolerint or resistance toward insect pests. Alpha latice design with three replicates were used in this experiment. The varieties were grown in two-row plots of 5 m length at row-to-row spacing of 75 cm and hill-to-hill spacing within rows of 25 cm. 300 kg Urea, 150 kg SP-36 and 100 kg KCI ha_1 was applied to the trial. Insect pests damage were observe d at 16 and 80 days after planting. The results showed that there were 12 genotypes have moderate resistance toward insect pests: CMS 991006, CTM 011004, CMT 011018, CMT 011028, CMT 011030, CMT 011036, CMT 011038, CMT 011044, CMT 011050, CMS 951220 (RE), CMT 011056, CMT 011060 and one genotype was susceptible that was CMS 991018, however the others showed varies resistance traits against insect pest.
