The development of cropping patterns is very important to support the increase in the rice cropping index to increase production. Efforts to increase the rice cropping index are based on the availability of superfast varieties which can increase the rice cropping index in rainfed lowland and dry land. The study design was a randomized block design. This study was conducted with 2 cropping patterns, namely 1) paddy-paddy-paddy using Inpari 24, Inpari 31, and Inpari 34 varieties; and 2) paddy-peanut-paddy using Inpari 31 and Inpari 34 varieties, while the peanut variety used are Talam 2. The method of analysis of the results of the assessment is carried out with descriptive and explanative methods for the socio-economic aspects. While the technical aspects, the data collected will be analyzed using ANOVA analysis, and further testing is carried out using the LSD test at the 5% level. The results of the study show that the development of paddy-paddy-paddy and paddy-peanut-paddy cropping patterns can be carried out well if there is sufficient water availability. The use of paddy-paddy-paddy cropping patterns must be supported by the availability of early-age paddy seeds and sufficient water availability. The cropping pattern for paddy-peanut-paddy using peanut Talam 2 variety. Fromaneconomicaspect is more feasible than the paddy-paddy-paddy, but cropping pattern with a size of R / C 2.03. In terms of advantages, the paddy-paddy-paddy cropping pattern has a greater advantage than the paddy-peanut-paddycroppingpattern.

The former quartz sand excavation land is a potential land for agricultural land. This land generally contains sufficiently high sand and very low fertility. The use of new superior varieties adaptive and tolerant can increase production. This study was carried out in the experimental field owned by BPTP in Gantong Village, East Belitung Regency, Bangka Belitung Islands Province. The design used was a randomized block design using three types of superior varieties, namely Inpari 22, Inpara 3, and Inpara 5. Each replication was repeated 3 times. Planting uses the jajar legowo system 4:1 (25 x 15) x 40 cm with 2-3 seedlings/planting holes. The fertilizer used is NPK 15:15:15 300 kg/ha and Urea 100 kg/ha. Urea fertilizer is given 3 (three) times each when plants are 7 days after planting (HST) as much as 25%, 25 HST as much as 50%, and 45 HST as much as 25% dose. Lime and organic fertilizer with a dose of 1 ton/ha each. Parameters observed included plant height, number of tillers, and production. The results of the study indicate that the growth of Inpara 5 has better than other varieties. The highest plant height and number of tillers are owned by Inpara 5, but not significantly different than Inpara 3 and Inpari 22. From the aspect of production Inpara 5 (2.23 t/ha) is significantly different from the varieties Inpara 3 (1.51 t/ha) and not significantly different from Inpari 22 (2.21 t/ha).
