This research was conducted to determine the financial feasibility of growing soybean varieties and their competitiveness in the rice-based cropping system of Indonesia. The research was conducted at two locations in 2020. The results showed that the use of improved varieties of soybean yielded 2.24 t/ha and 2.09 t/ha, which was higher than using local (non-improved) varieties. The use of improved varieties was financially feasible with Revenue Cost (R/C) ratios of 1.88–1.98 and Benefit Cost (B/C) ratios of 0.88–0.98. The competitiveness of soybeans in Mojokerto and Pasuruan was lower compared to maize and mungbean. Soybean could compete with competing crops if the productivity and price were higher than the current conditions. To be able to compete with maize, the soybean productivity should be 5.14–5.22 t/ha if the current soybean price per kg is IDR 7200 (about US $ 0.51). To compete with mungbean, the soybean productivity should reach 3.05 t/ha with the current price per kg of IDR 7200 (about US $ 0.51). When measured by the price level, to be able to compete with maize, the soybean selling price per kg should be IDR 14,428–IDR 14,893 (about USD 1.06) with a productivity level of 2.24 t/ha.
<p>Improved soybean varieties are generally possessing high yield, resistant to major pests and diseases, and carrying other important properties. Until 2013 more than 70 improved varieties had been released, but not all are planted by farmers. The present research objectives were: (1) to identify the distribution and farmers preferences of improved soybean varieties, (2) to identify the adoption barrier of new soybean varieties, and (3) to estimate the economic contribution of the new soybean varieties. The study was conducted on soybean production centers in Indonesia, covering East Java, Central Java, West Nusa Tenggara, Nanggroe Aceh Darussalam, West Java, and South Sulawesi. The research was carried out using survey method, where samples of farmers were used as sources of the primary data. There were total of 600 farmer respondents. Analyses of the data applied the tabulation analysis, principal components analyses, and contributions analyses. The results showed that soybean varieties most widely adopted by farmers in order of the highest were: Anjasmoro (32.1% farmer users, covering area of 190,567 ha), Willis (17.9% farmer users, area of 93,187 ha), Mahameru (9.1% farmer users, area of 78,190 ha), Grobogan (11.2% farmer users, area of 71,576 ha). Farmer’s preferences to soybean variety, included the following characters: flowering at 35-40 days after planting, harvesting 70-75 days after planting, stem with many branches, yellow seed coat color, round seed shape, large seed size, and the grains sold easily. The reason of varieties was not being adopted by farmers include: unavailability of seeds at planting time, seed size was too small, seed price is too expensive, and the distance from farmers’ home to the seed kiosk was too far away. The economic contribution of improve soybean varieties was as followed: Anjasmoro (Rp 1.3 trillion), Mahameru (Rp 0.61 trillion), Grobogan (Rp 0.61 trillion), Willis (Rp 0.56 trillion), Baluran (Rp 0.25 trillion), while the other improved varieties (Argomulyo, Bromo, Orba, Kipas Merah, Galunggung, Kipas Putih, Davros, Gepak kuning, Gepak Hijau, Malabar, Burangrang, Mitani, Kaba, Lokon, Sinabung) each contributed to the rural economy in a total of Rp 0.57 trillion. The total economic contribution of all improved soybean varieties was estimated at Rp 3.9 trillion.</p>
The main constraints of the tidal swamp lands in Indonesia for soybean growth are low soil pH, high Al saturation, and low nutrient availability of N, P, K, Ca, and Mg. The objectives of this research were to determine tolerance of several soybean varieties to Al saturation level, and to obtain a technological package for soybean cultivation which was suitable for farmers to adopt on tidal swamp lands. The research consisted of two stages of study. The first stage formulated of technology package, and the second stage evaluated feasibility of the technology package which was formulation from the first stage. The first stage studied the effect of dolomite application (20% - 30% of soil Al saturation) on four soybean varieties (Anjasmoro, Panderman, Dega 1, and Demas). The second stage studied the effect of three technological packages: existing technology; water- saturated soybean cultivation (WSC); and alternative technology which was formulated from the results of the first study. In the 30% of soil Al saturation condition, the alternative technology package (application of 50 kg urea + 75 kg SP36 + 50 kg KCl + 1500 kg organic fertilizers/ha + rhizobium biofertilizer “Agriosy” 0.25 kg/50 g seeds/ha) gave soybean yield of 1.78 - 2.72 t/ha for all of soybean varieties tested. The alternative technology package with Anjasmoro variety provided higher seed yields (2.62 t/ha) compared to the existing technology (2.07 t/ha) and WSC technology package (2.44 t/ha). The alternative technology package gave a profit of 11,595,000 IRD/ha with B/C values of 1.71 which was higer than the existing and WSC technology packages. The alternative technology package was more profitable than the existing technology (current farmer practice) and water-saturated soybean cultivation technology packages.
Climate change is a major factor endangering sustainable food production. Various efforts have been made to prevent potential food shortages in future. Meanwhile, access to adequate food is an important part of human rights. In Indonesia, the opportunity for cassava development is still widely open and has potential to provide for the world’s needs in future. Cassava is well-known by farmers in Indonesia and can be easily cultivated in all areas of Indonesia, even though the soil fertility is low. The current problems are that cassava is still considered as an inferior commodity and is only used for direct consumption. Indonesia is able to meet the world\'s cassava needs only by utilizing 54% of the total available land, which is suitable for planting cassava. Cassava utilization is actually large and has potential as raw material for many strategic industries. The map of cassava development in Indonesia is in the phase of growth and product expansion (diversification). Thus, the efforts in preparing cassava in Indonesia to meet the world’s needs in future, including (1) increasing cassava productivity, (2) improving cassava added value by-product diversification, and (3) enhancing cassava bio-economy by implementing a bio-industry system integrating cassava and livestock farming.
Tujuan utama kajian ini adalah untuk menelaah dinamika preferensi dan penyebaran varietas kedelai. Kajian ini ditulis berdasarkan suatu “review” beberapa studi perilaku petani. Hasil kajian memberikan gambaran bahwa dinamika preferensi petani terhadap varietas kedelai memberikan makna terjadinya pergeseran preferensi petani dari ukuran biji kecil-sedang ke ukuran biji besar di daerah Jawa Timur. Hal ini memberikan implikasi upaya penyebaran varietas unggul kedelai dengan ukuran biji besar mempunyai peluang untuk dapat diterima petani.
