Implementation of good cultivation systems can improve onion (Allium ascalonicum L.) yield. The purpose of this study was to determine the effect of tuber cuttings and the  dose of NPK fertilizer on the growth and yield of onion. The experimental design was factorial randomized block design arranged consisting of two factors. The first factor was tuber cuttings which consists of without and with  ¼ and 1/3 cut; the second one was dosage of NPK fertilizer which consists of without and with 200 kg/ha; 400 kg/ha; 600 kg/ha. There are 12 combinations of treatments, each of which is repeated three times. The results showed that there was no interaction effect between tuber cutting and NPK dosages on growth and yield of onion. independent effect of tuber cuttings and NPK dosages also didn’t inflence both parameter. Tuber cuttings  only increase pant height at one and two weeks after planting. Overall, cutting-quarter of the tuber could induce better fresh  weight and dry weight of tubers although statistically didn’t significant.

This research aimed to determine (1) land suitability limiting factors for Javanese patchouli cultivation in North Serang Regency, Banten Province, (2) the level of land suitability for Javanese patchouli cultivation in North Serang District, Banten Province, (3) land improvement efforts to be suitable for Java Patchouli Plant cultivation in North Serang Regency, Banten Province. This type of research was descriptive research. The study was conducted in the Dry Land of North Serang Regency, Banten Province including Tirtayasa District, Kramatwatu District, and Waringinkurung District. The research was conducted from October 2018 to March 2019. The research consisted of 5 stages: preparation and secondary data collection, preparation of land unit maps, data collection stage in the field (primary data), analysis of land suitability data and stages making land suitability maps. The method of data analysis was done by matching between the characteristics and quality of land in the study area with the criteria for growing patchouli plants. The results showed that : (1) Land suitability limiting factors for Java Patchouli cultivation included the availability of water, rooting media, nutrient availability, terrain conditions. (2) Land use in Tirtayasa sub-district includes land suitability classes S2 (moderately suitable) and S3 (marginally suitable). Land use in Kramatwatu District includes land suitability classes S2 and S3. Land use in Waringinkurung District includes land suitability classes S3 and S2. (3) Efforts to improve land can be made by making terraces, providing efficient additional irrigation, making drainage channels, liming, fertilizing, adding organic matter.

Limited water availability or drought is an abiotic factor that inhibited rice production. One of the efforts to overcome this problem is by using plant varieties that can adapt to conditions of limited water availability. This study aims to determine the physiological and agronomic responses of some local rice cultivation in South Banten to drought conditions. The research was conducted from April to October 2017 in the greenhouse of the Faculty of Agriculture, Sultan Ageng Tirtayasa University, Banten. The experiment was based on factorial experiments in a completely randomized block design (RBD) with 3 replications. The first factor is the frequency of irrigation which consists of 2 levels, namely irrigation every 7 days and every 9 days. The second factor is the local rice cultivar in South Banten which consists of 8 levels, each of which consists of 7 local cultivars and one comparison variety, namely Rencong, Ketan Dewo, Kiara, Inpari 10 (as comparison varieties), Super, Kapundung, Cimoherang, and Ketan Elfi. The results of research show that cultivar of Ketan Dewo adaptive in drought environments.
