Climate change causes change in rainfall patterns, which will affect water availability. Water is a limiting factor for rice production on dry land. Increasing rice yields on dry land requires precise water management. This study aimed to investigate the effect of supplementary irrigation when it does not rain on rice yields in dry land during rainy season. The research was conducted on dry land in Playen, Gunung Kidul, Daerah Istimewa Yogyakarta, Indonesia during rainy season of November 2020 to February 2021. The treatments were supplementary irrigation if 1 day without rain (A1), if 2 days without rain (A2) and if 3 days without rain (A3), and they were compared to control without supplementary irrigation (A0). This research used a randomized completely block design, each treatments replicated 4 times. The results showed A1 gave the highest grain yield, namely 7.786 ton ha−1, significant different with other treatments of A2, A3 and A0. Dry straw of A1 was 7.324 ton ha−1, significant different with A2, A3 and A0. Carbon absorption of A1 was 6.860 ton ha−1, consisting of carbon in grain 3.575 ton ha−1 and straw 3.285 ton ha−1, it was significant different with other treatments of A2, A3 and A0 (p<0.05; n=16). B/C A2 1.73 was highest from the others and its farmers have profit Rp. 19,276,360 ha−1.
Agriculture is one of the dominant sectors in the economic structure in Daerah Istimewa Yogyakarta. This is because the agricultural sector contributes to meeting food needs and the supply of industrial raw materials. The corporate farming (CF) program located in desa Trimulyo, Daerah Istimewa Yogyakarta is one of the empowerment programs for farming communities by farming in groups. The purpose of this study was to determine the implementation of the CF program and the impact of the CF program on labor efficiency at the farm level. The research method used was descriptive qualitative and quantitative with t-test. The method of determining the sample was purposive with 30 farmers as respondents. The technique of collecting data was done by observation, interview and questionnaire. The results showed that the CF program is a program by combining several farmer-owned lands into one large area (land consolidation) and carried out jointly in one management from land preparation to harvest using modern agricultural tools and machines. The rice productivity produced by farmers before the CF program was 323.03 Kg/UT or 3,654.05 Kg/Ha. After the existence of the productivity program is 268.13 Kg/UT or 3,032 Kg/Ha. The need for labour in one season prior to the program was 43.8 HOK/UT or 1,464.76 HOK/Ha. The need for labor after the program was 31.52 HOK/UT or 716.79 HOK/Ha. The impact of the CF program on labor efficiency shows no significant difference. This means that the efficiency of the labor before and after the program is the same.
Dryland has the potential to increase agricultural production, by increasing the cropping index. The main problem of dryland is the availability of water which depends on rainfall. Groundwater can be an alternative option to meet the availability of water in the dryland. This study aimed to determine the cropping pattern and increase of cropping index supported by groundwater irrigation in the dryland. The research was conducted in the dryland of Playen, Gunungkidul, Special Region of Yogyakarta, supported by groundwater irrigation. This research used a combination of survey, interview and plot demonstration methods. Surveys and interviews were conducted to determine the condition of cultivation and profit in the first and third growing seasons. The plot demonstration, to increase the rice cropping index from 1 to 2, was applied in the second growing season. The results showed that rice productivity in the first growing season was 5.215 ton ha<sup>-1</sup>, with a profit of 12,288,000 IDR ha<sup>-1</sup> and B/C of 1.28. In the second growing season, Sidenuk productivity was 8.025 ton ha<sup>-1</sup>, with the dry straw of 8.049 ton ha<sup>-1</sup>, grain carbon of 3.471 ton ha<sup>-1</sup> and straw carbon of 3.723 ton ha<sup>-1</sup>, higher than those of Situbagendit, but comparable those of Inpari-42, with a profit of 20,700,000 IDR ha<sup>-1</sup> and B/C of 1.54. Rice contributed to higher biomass, carbon and profit than groundnut. In the third growing season, groundnut productivity was 2.026 ton ha<sup>-1</sup>, with a profit of 15,572,000 IDR ha<sup>-1</sup> and B/C of 1.78. Groundwater irrigation can support the increase in the cropping index on dryland and intensify agricultural production as well.
<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>
