A field research was conducted at Makariki Experimental Farm, Moluccas Assessment Institutes for Agricultural Technology, Central Moluccas. The study aims to know the effect of tillage systems and fertilization for increase of growth and yield of yam’s local tuber (Dioscorea esculenta). Experiments using split plot design with 20 treatments and three replications. The main plot were tillage system consisted of four tillage systems, ie: (A1) Minimum Tillage + Single Mound/”Kuming”; (A2) Minimum Tillage + Lenghtwise Mound/”Guludan”; (A3) Intensive Tillage + Single Mound, and (A4) Intensive Tillage + Lenghtwise Mound, sub plots were fertilization, consisting of (B0) Without fertilizeration; (B1) Complete NPK Fertilization (135 kg N +135 kg P2O5 + 90 kg K2O/ha), (B2) NP Fertilization (135 kg N + 90 kg P2O5 /ha), (B3) NK Fertilization (135 kg N + 135 kg K2O/ha), and (B4) PK Fertilization (90 kg P2O5 + 135 kg K20/ha). Sub plot size 4 m x 3 m with spacing of 100 cm x 75 cm. Source of fertilizer N, P and K in a row came from Urea, TSP, and KCl. Fertilizer N and K are given three times, i.e. the one third dose given at age 10 dap (days after planting), one third dose at age 30 dap and the rest one third dose at age 60 dap, whereas the P fertilizer entirely given at age 10 dap. The results showed that the tillage system and fertilization in single influence on growth, yield components and yield per hectare of yam’s local tuber, but both are no significant interactions. Intensive tillage system, followed by creating lenghtwise mound influence the growth and yield components as well as providing the highest yield of yam’s local tuber (19.97 t/ha). Complete NPK fertilization (135 kg N +135 kg P2O5 + 90 kg K2O/ha) also provides a real influence on the growth and yield components as well as providing the highest yield of yam’s local tuber (21.86 t/ha) and not significantly different compared to the NK fertilization (135 kg N + 135 kg K2O/ha) which consist of 19.58 t/ha.

Millet (Setaria italica (L) Beauv.) is classified as a cereal plant, potentially developed as an alternative food ingredient to support food self-sufficiency in the region and nationally. The study was carried in Waeperang, Lilialy Subdistrict, Buru Regency in 2017 with the aim of obtaining recommendation for technology package for millet-based double cropping that was able to increase productivity > 20%. The study was carried out with an adaptive approach, field trial approach, and dry land agroecosystem approach, using Randomized Block Design with four treatments and repeated five times (farmers as replications). Four treatments were tested, namely: (1) Technology of Existing Planting Pattern (Millet - Peanuts - Fallow), (2) Technology of Improved Farmer Planting Pattern (Millet + Corn - Peanuts - Fallow), (3) Technology of Introducing I Planting Pattern (Millet + Corn - Peanuts - Mungbeans) and (4) Technology of Introducing II Planting Pattern (Millet + Corn/Cassava - Peanuts - Mungbeans). The results of the study indicated that the multiple cropping pattern based on millet can increase productivity of millet compared to monoculture. Intercropping of millet, namely Introduction I Planting Pattern (C Pattern): Millet + Corn - Peanuts - Mungbeans and Introduction II Planting Pattern (D Pattern): Millet + Corn/Cassava - Peanuts - Mungbeans can increase the productivity of millet crops are 23.04% and 51.55%, respectively. Introduction D Pattern (Millet + Corn/Cassava - Peanuts - Mungbeans) can be recommended as a double cropping pattern on dry land in Moluccas, and support dimensions of a food security, i.e access, availability, utilization and stability of food.

Moluccas widely recognized by the world community as a centre of high genetic diversity, including commodities producer of high economic value, such as estate crops. Although Moluccas has substantial resources, but has not been able to provide adequat e welfare for society because natural resources are available not optimally managed. Therefore, it is necessary to study the potential of land for the development of the estste crops. This research aims to determine the land potential and his referrals use for the development of estate crops on Buru Island (Buru and Southern Buru Regency). The methodology used was a desk study of some libraries and field observation. Land potential of Buru Island for developing a estate crops based on data analysis and use of existing biophysical taking into account the status of the forest is an area of 86,140 ha covering an area of moderate to high potential area of 58,650 ha, and low potential areas covering an area of 27,490 ha with limiting factor drainage, rooting conditions, nutrient retention, slope, rooting conditions, floods, water availability, and slope. Wherever according by Agro-Ecological Zone (AEZ) approach from AIAT Moluccas with using AEZ analysis data, present land use, and statistical data for 8 years (2009 – 2016) is an area of 34,923.36 ha with covering sub zone II ax 15,952.78 ha, sub zone II ax.i 8,924.26, sub zone II ay 5,887.99 ha, and sub zone II ay.i 4,158.33 ha.

Upland rice-based cropping pattern is a form of multiple cropping including intercropping, sequential planting, and relay planting where upland rice as a base crop can be preceded and/or rotated with other food crops as a secondary crop. The research was aimed to provide recommendations for upland rice-based cropping pattern technology in dryland agroecosystems in Maluku that would be able to increase land productivity > 1.00 (MCI = Multiple Cropping Index > 100%) compared to existing cropping patterns. The study used a Randomized Block Design (RCBD) with four treatments and repeated five times (farmers as replications). Four treatments for upland rice-based planting pattern technology assemblies, namely: 1) Pattern-A (Farmer A Pattern); 2) Pattern-B (Farmer B Planting Pattern B); 3) Pattern C (Farmer Improvement Cropping Pattern); and 4) Pattern D (Introduced Plant Pattern). The results showed that upland rice was planted double (multiple cropping) through intercropping and/or sequential cropping, namely Improved Cropping Patterns (Pattern C = Upland Rice + Corn - Peanuts) and Introducing Cropping Patterns (Pattern D = Upland Rice + Corn/Cassava - Green Beans - Peanuts) can increase land productivity with a double-cropping index 1.35 - 1.80 (IPG = 135% - 180%) compared to upland rice grown in monoculture (Farming Patterns). Multiple cropping (Upland Rice + Corn/Cassava - Green Beans - Peanuts) can be recommended as Upland Rice-Based Planting Technology Package on dry land in Maluku, because it can increase land productivity> 1.00 with an MCI (Multiple Cropping Index) of 180%.
