Abstract

Abstrak. Wilayah lahan kering beriklim kering pada umumnya memiliki curah hujan rendah kurang dari 2000 mm/tahun. Keterbatasan air dan kesuburan tanah yang rendah menjadi kendala dalam pengembangan lahan jenis ini. Selain itu kondisi lahan pada umumnya berbukit dan bergunung dengan solum tanah dangkal dan berbatu. Salah satu upaya peningkatan produktivitas lahan ini adalah melalui aplikasi panca kelola lahan kering iklim kering guna mendukung swasembada pangan, meliputi: pengelolaan air; pemupukan berimbang; pengelolaan bahan organik, ameliorasi dan konservasi tanah; integrasi tanaman ternak; dan penguatan kelembagaan tani. Produktivitas lahan dan indeks pertanaman yang rendah di lahan kering iklim kering memungkinkan untuk ditingkatkan melalui pemberian irigasi suplemen. Sumber irigasi suplemen dapat berasal dari bangunan panen air berupa embung, dam parit, long storage, pemanfaatan air sungai, air tanah dangkal dan dalam. Aplikasi irigasi hemat air bagi tanaman sangat diperlukan pada kondisi air terbatas. Pemupukan berimbang dengan teknologi nano; pengelolaan hara terpadu yang mengkombinasikan pupuk anorganik dengan pupuk organik dan pupuk hayati; pemanfaatan limbah tanaman untuk pakan ternak dan sebaliknya kotoran ternak untuk bahan organik bagi tanaman; serta pendampingan dan pembinaan kelembagaan secara intensif perlu dilakukan untuk keberlanjutan pertanian lahan kering iklim kering. Abstract. Dryland with dry climate areas generally characterized by low rainfall of less than 2000 mm/year. Water limitations and low soil fertility become obstacles in the development of this type of land. In addition, land conditions are generally have a hilly and mountainous area, shallow solum and rocky soil. One of the efforts to increase land productivity is through the application of five land management of dry land with dry climate area to support food self-sufficiency, such as: water management; balanced fertilization; organic matter management, amelioration and soil conservation; livestock crop integration; and strengthening farmer institutions. Low land productivity and cropping index in dry land with dry climate area makes it possible to increase through the aplication of supplementary irrigation. Sources of supplement irrigation were come from water harvesting infrastructures such as water reservoir, channel reservoir, long storage, river water utilization, shallow and deep ground water. Water saving irrigation are very necessary in limited water conditions. Balanced fertilization with nano technology; integrated nutrient management that combines inorganic fertilizers with organic fertilizers and biological fertilizers; utilization of crop waste for animal feed and vice versa livestock manure for organic material for plants; and intensive institutional assistance and guidance, needs to be carried out for the sustainability of dry land with dry climate agriculture.

Abstract

The productivity of chili and shallot in Indonesia is still low, but Indonesia has great opportunities to increase chili and shallot productivity either through intensification and extensification. The objectives of the research are (1) to compile and develop land resources data, including climate and hydrology information in chili and shallot regions, (2) to compose maps of chili and shallot development regions. (3) to create recommendations on land, climate, and water management for chili and shallot development regions. Map of development of chili and shallot areas scale 1: 50,000 carried out by desk work and field verification. Recommendation of the development of chili and shallot commodity areas are arranged based on land suitability class by considering existing land use, and commodity centers on APL land (Other Use Areas). The results of the analysis show that Bima District has an area of 8,696 ha of shallot area and potential for extensification development of 60,363 ha, high development potential (P.1) covering an area of 4,675 ha and moderate (P.2) 55,688 ha. P.1 is quite suitable with the dominant nitrogen and phosphorus nutrient inhibiting factor, P.2 is marginal according to the dominant limiting factor of low rainfall. While for chili do not have an area because the existing land is scattered in a narrow area, but has a development potential of 46,159 ha consisting of high development potential (P.1) covering 3,280 ha, and moderate (P.2) covering 42,879 ha.
