Performance and determinants of farmers in  adoption decision of innovation for swamps rice cropping system in South Sumatra. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands. 8(2):181-191. The development of food crops in swamplands became one of  main focus of the government in the development of rice farming in Indonesia. A variety of ecological constraints that accompany the development of agriculture in swamp land overcome by a variety of technological innovations, one of which is with the application of Cropping Index 200 (CI 200) technology. After nearly 5 years of CI 200 technology applied on swamp land is considered necessary for analysis related to the performance of socio-economic of farmers in the adoption of technology innovations CI 200. This study aimed to analyze the socio-economic condition of farmers in adopting IP 200 technology innovation, and analyze the determinants of IP 200 technology adoption decisions. Research was using the survey method and has been carried out in 2 districts, namely Tanjung Lago sub-District, Banyuasin District and Pemulutan sub-District, Ogan Ilir District in June-July 2019. Sampling method used disproportionate stratified random sampling. The analysis of the data was using tabulations, mathematical and logistic regression analysis. The results of the analysis showed that there were differences in the performance of the socioeconomy of farmers adopting and not adopting. The performance of the socio-economic of farmers who adopt were better than farmers who did not adopt the technology CI 200. The factors that determine the farmers adopt were the age, education, origin, experience, income, and the cost of farming.

The research aimed to evaluate the effect of biochar application and water table treatment on growth and yield of shallot plant. The research was conducted in Experimental Farm of Agriculture Faculty, Sriwijaya University at 2019. Materials used consisted of shallot bulb of Bima Brebes variety, oil palm shells biochar, paper bag, and plastic bag. While the tools used were hoe, gauge, pH meter, basin, scale, and oven. Factorial Randomized Block Design was used with two factors and three replicates. The first factor was biochar dosages consisting of P1 (51 g/plant) and P2 (102 g/plant) and the second factor was soil water table consisting of T0 (no water table treatment), T1 (10 cm of water table below soil surface), T2 (15 cm of water table below soil surface) and T3 (30 cm of water table below soil surface). The observed parameters included plant height, leaf number, tiller number, total bulb fresh weight, bulb fresh weight, bulb dry weight and root length. Results showed that the application of biochar and water table treatment statistically affected the growth and yield of shallot plant. The effect on both growth and yield parameters were obtained from the combination of P2T3. Correlation was found between plant height and leaf number, total bulb fresh weight and bulb fresh weight.

Harahap SM, Ramija KE, Erythrina E. 2020. Yield response of peanut (Arachis hypogaea L.)  to compound fertilize. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands 9(1): 41-49.The purpose of this study was to evaluate the application effects of three different compound fertilizers on yield, and assess the income increase at different rates of compound fertilizers. Three compound fertilizers namely NPK 14-0-46, NPK 19-9-19 and NPK 11-11-11 was conducted at three different farmers’ field in Langkat District, North Sumatra Province under upland conditions. In each farmers’ field, a Randomized Complete Block Design was applied with four replications per treatment.  Seven treatments tested consisted of full rate of farmer fertilizer practice and six rates of each compound fertilizer plus half rate of farmer fertilizer practice. In each of compound fertilizer tested, pod yield and seed yield increased quadratically as increasing compound fertilizer rates. The highest pod yield and seed yield of peanut were 1649 kg/ha and 1072 kg/ha, respectively with half rate of FFP + 200 kg of NPK 14-0-46. For compound fertilizer NPK 19-9-19 the highest pod yield and seed yield were 1632 kg/ha and 1032 kg/ha with half rate of FFP + 500 kg of NPK 19-9-19 while for compound fertilizer NPK 11-11-11 the highest pod yield seed yield were 1421 kg/ha and 930 kg/ha with half rate of FFP + 250 kg of NPK 11-11-11. However, adding each  half rate of farmer fertilizer practices with  200 kg of NPK 14-0-46 or 300 kg of NPK 19-9-19 or 250 kg of NPK 11-11-11 with HypoMa-1 cultivar gave the highest values of the benefit for the farmers under upland soil in Langkat, North Sumatra.

Abstract

Muharani L, Yazid M, Adriani D. 2020. Evaluation of smallholder oil palm plantation sustainability in tidal lowlands of Pulau Rimau Sub-District of Banyuasin Regency. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands 9(1): 80-88.Oil palm is one of the estate commodities that has an important role in the economic activities of the people. Smallholder oil palm plantation as part of the estate still face several constraints, including lack of productivity, institutional inactivity, plantation management that do not meet the standard, farmers' lack of knowledge, and difficulty in obtaining credit. Due to these constraints, oil palm plantation sustainability is put into priority. Oil palm development issues are discussed not only on the economic aspects but also on the environmental aspects. This research is aimed at analyzing the level of oil palm sustainability and evaluating the condition of smallholder oil palm plantations according to the stages of plant development. This research used survey method and was carried out in tidal lowlands of Pulau Rimau Sub-district, Banyuasin Regency in August-September 2019. Smallholder oil palm households were selected using proportionate stratified random sampling. The results showed that there were three aspects of sustainability that were in low criteria, namely institutional, social, and technical aspects. Whereas, economic and environmental aspects were in medium criteria. The average sustainability value of non productive and productive oil palm plantations was in low criteria. Smallholder oil palm households were expected to understand and follow the standards set by ISPO, with the support from local governments and related agencies.

Abstract

Acidic soils are characterized by low soil pH and high solubility of iron and aluminum affecting the availability of P to be low. The P concentration in the soil solution around the rhizosphere will be influenced by the presence and metabolism of plant roots. Plants get P in the form of inorganic phosphate anion (Pi) from soil solution.  Exudate will affect the activity of microorganisms in rhizosphere and rhizoplan. This paper aimed to review the factors that affect P metabolism in the rhizosphere region. Some of the factors that influence the P metabolism in the rhizophir region are pH, root exudates, microorganisms, temperature, and humidity. Nutrient transformation in the rhizosphere was very narrow. Several things affecting the P transformation include temperature, humidity regime, oxygen, pH and ion availability, sunlight, and CO2. In the soil deficient in P, the plant roots undergo adaptation through changes in root morphology. The P availability in acid soils can be increased by the integration of plants with phosphate solubilizing bacteria or fungi. It is hoped that an understanding of P metabolism in the rhizosphere can determine a more efficient P management effort.

Abstract

Priatna SJ, Rahman D, Supriyadi S. 2020. Land suitability assessment for some carbohydrate food crops at wetland area in Arisan Jaya. Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 117-126.The nature condition and lack of knowledge about soil characteristics have become a limitation for crops cultivation and development in Arisan Jaya. This study aimed to determine the type of crops that has potential to be developed in site. The assessment was carried out in Arisan Jaya, Pemulutan Barat Sub-District, Ogan Ilir Regency, South Sumatera from April to August 2015. The study method is 1:30.000 semi-detailed survey. The location of the sample was determined by grid method with one sample for every 1.000 meters with 10 sample sites. A disturbed soil sample was taken as deep as 150 cm from the ground surface. Land characteristics data were matched with crops growth requirements based on the suitability classes set for wetland rice, dry land rice, corn, cassava and sweet potato. The distribution of soil properties was known by IDW (Inverse Distance Weighting) interpolation method, which was overlapped to determine the distribution of land suitability classes. Very acidic soil conditions was a major limiting factor for crops cultivation in general (the actual suitability class is Nf). Wetland rice was relatively more suitable to be cultivated than dryland rice in the site.  Corn and cassava could be planted as rotational crops before the rainy season or after rice season, although the productivity would not be optimal (S2 potential suitability class). Climatic conditions was another limiting factor for the development of sweet potato at the site (S3 potential suitability class).

Abstract

Agustini S, Suparman S, Tridamayanti HC. 2020. Landuse planning for food crop areas development using land resource evaluation approach and gis application (a case study of Pulang Pisau District, Central Kalimantan Province). Jurnal Lahan Suboptimal: Journal of Suboptimal Lands  9(1): 64-72.In order to promote sustainable landuse, the need of landuse planning is urgently required and it can be designed based on the result of spatial land resource data management. Land resource evaluation is main component for landuse planning which this procedure was applied to determine land allocation for arable lands for rice farming development. The use of geographic information system (GIS) technology was also employed not only for spatial data management, but they could also be applied to support decision making within establishing landuse planning. The objective of this study was to allocate the arable lands for extensification and intensification regions as main part of landuse planning for food crops areas development.  In the case of Pulang Pisau District, land allocation for extensification and intensification regions were mainly found in southern part and mostly located at  watershed areas with each total areas respectively of 380,261 hectares (36.81%) and 29,941 hectares (2.90% of total areas of Pulang Pisau District). In order to support these potential areas, specific programs could then be formulated to increase the yield and productivity for these regions.
