Irigasi Air Tanah Mendukung Pertanaman Kacang Tanah, Jagung dan Kedelai di Lahan Kering pada Musim Kemarau

Abstract

<p><em><span lang="IT">The provision of water for plants is a major component supporting the success of planting on dry land. One source of water that can be utilized is groundwater. This study aims to determine the use of groundwater in supporting the cultivation of groundnut, corn and soybeans on dry land during dry season. The study used plots of farmers' land to grow groundnut, corn and soybeans complete with technology packages for each commodity. The application of technology includes cultivating groundnut by farmers and cultivating groundnut, corn and soybeans according to the recommended technology components. Harvest data were analyzed descriptively. Economic analysis is used to calculate the profitability and feasibility of farming. The results showed that corn plants with technology recommendations gave the highest yield, dry seeds of 5.50 tons ha<sup>-1</sup>, dry biomass of 18.63 tons ha<sup>-1</sup>, with carbon absorption in seeds of 2.62 tons ha<sup>-1</sup> and biomass of 8.92 tons ha<sup>-1</sup>. The profit from corn cultivation was 22,090,000 IDR ha<sup>-1</sup> with a benefit-cost (B/C) of 1.35, groundnut 20,985,000 IDR, with a higher B/C of 1.50. Soybean plants provide the lowest profit and B/C, amounting to 4,124,000 IDR and 0.26. Technologically and economically, the cultivation of groundnut, corn and soybeans with the support of groundwater irrigation is feasible to develop on dry land during the dry season. Socially, groundnut is more accepted by farmers.</span></em></p>

'Pot cultivation' as a form of soil and water conservation technique for adaptation to soil condition and climate change in karst area

“…The implementation of PC must be in accordance with the socioeconomic of farmer and fulfilled with principle of sustainability. PC quality can be improved through improving inputs, such as application of rice husk charcoal and organic fertilizer as in [26,27,28], to increase water absorption and improve nutrients, as an alternative technology, especially for seasonal crops. Another alternative technology, management of irrigation water [29,30,31] and cropping pattern [32,33,34], with the potential for irrigation water in karst area from spring or underground river [35,36].…”
