Central Sulawesi

Central Sulawesi’s rice productivity in 2019 was lower compared to that in 2018. One of the problems for the low productivity of paddy in Central Sulawesi is the application of low quality of seeds. Ministry of Agriculture through Central Sulawesi AIAT has introduced a numbers of new high yielding varieties (HYV) to increase rice production and productivity. To support the dissemination of new HYV, it is important to study the rice varieties that mostly used by farmers in Central Sulawesi. The objectives of this study are to identify the rice varieties and the preferred characteristics of rice varieties that farmers usually used in Central Sulawesi. This study used primary and secondary data. Data were analyzed descriptively and presented in tables and graphs. The results show that most farmers in Central Sulawesi use Mekongga, Ciherang, and Cisantana varieties, and local varieties such as Peluncur, Dewi, Ntabone and others. Farmers generally prefer varieties which tend to produce higher yields and resistant to pests and diseases. To maintain the availability of the varieties in Central Sulawesi, it is important to train farmers to become breeders.

<p>In the middle of 1980s, rice self-sufficiency in Indonesia has been achieved, but the growth of rice production slowed down since the 1990s. Narrow genetic variability of released rice varieties contributed largely to the occurrence of leveling of potential rice yield over the past decades. To enlarge the genetic variability, an intersubspecies crossing of Koshihikari (japonica) and IR36 (indica) has been performed. Through this crossing, three high yielding and high yield quality promising lines of KI 37, KI 238, and KI 730 have been obtained. The objective of this study was to evaluate the superiorities of these lines through multi-location yield trials, pests, diseases, and grain qualities examinations. Examination methods used followed the release food crops variety procedure issued by the Indonesian Ministry of Agriculture. The result of examinations showed that the average yield of KI 730 was 7.47 t/ha, it was significantly higher than that of Ciherang (6,73 t/ha). KI 730 has a good grain quality, with translucent milled rice, a high percentage of milled rice (78.0%) and head rice (91.01%). The texture of its cooking rice was soft, sticky, with the amylose content of 20.41%. In addition, pests and diseases resistances of KI 730 were better than those of other lines tested. After evaluation by National Food Crops Release Variety Team, the KI 730 line was released as a national superior variety with the name of Tropiko. Tropiko should become an alternative variety to grow widely in order to increase national rice production and farmers income.</p>

The Impact

Abstract Climate change negatively impacts rice productivity in different parts of Africa. As a matter of necessity, farmers must respond to changing the climate by choosing adaptation strategies that increase their productivities. Incidentally, studies that documented the impact of climate change adaptation actions of farmers on rice productivity are few. This study therefore analyzed the impact of climate change adaptation decisions of farmers on the profitability of rice production using cross-sectional data gathered from 240 rice farmers selected from Ebonyi State, an important rice-producing State in Nigeria, Africa's most populous country. Using descriptive statistics, multivariate probit regression, instrumental variable regression and endogenous treatment effect model, the study revealed that the common adaptation actions of rice farmers involved adoption of minimum tillage, bond and drainage, fertilizer, crop diversification, livelihood diversification, improved rice varieties, pesticide, nursery, and adjusting planting and harvesting dates. The study found several significant interactions between the choice of climate change adaptation actions and socio-economic, farm, institutional and location characteristics of rice farmers. The result further revealed that multiple adaptation decisions of farmers significantly increased returns to scale and profit of rice production. The study concludes that adaptation decisions are effective in increasing the profitability and returns to scale of rice production in the area and other regions with similar geographical, meteorological and socio-economic contexts.

ABSTRAKSalah satu faktor penting yang mempengaruhi peningkatan produksi padi adalah penggunaan benih unggul dan berkualitas. Penggunaan benih unggul dapat meningkatkan frekuensi panen menjadi tiga kali dalam setahun, meningkatkan mutu hasil dan sebagai sarana pengendali hama dan penyakit tanaman. Ketersedian benih unggul bersertifikat dalam kegiatan usaha tani merupakan syarat mutlak, meskipun dalam struktur ongkos usaha tani padi, proporsi pengeluaran untuk biaya benih tidak sampai 5% dari total pengeluaran, dibandingkan dengan pupuk (7-14%), lahan (14-34 %), dan tenaga kerja (30-62 %). Penelitian ini menggunakan data sekunder. Tujuan penelitian ini adalah merumuskan faktor atau kondisi yang menyebabkan penggunaan benih bersertifikat belum maksimal dan kondisi yang diperlukan agar penyerapan benih bersertifikat meningkat, dan agar adopsi teknologi benih unggul dan bersertifikat oleh petani berjalan baik. Hasil penelitian menunjukkan bahwa terdapat kendala yang dapat menghambat penggunaan benih bersertifikat, tetapi baru tiga yang dapat dibuktikan benar atau sesuai sedangkan kendala yang lain belum dapat diperoleh kesesuaian atau ketidaksesuaiannya. Tiga kendala tersebut adalah 1) Kontinuitas ketersediaan benih sumber BS untuk program Benih Dasar (BS-FS) belum terjamin; 2) Kurangnya jumlah penangkar benih dan 3) Pendidikan formal, pengalaman pribadi, dan pengaruh tokoh kunci. Serapan benih bersertifikat dapat meningkat antara lain jika kualitas benih bersertifikat ditingkatkan, kecukupan ketersediaan benih bersertifikat, penggunaan benih bersertifikat bisa meningkatkan produktivitas dan pendapatan petani secara riil.  Petani merasa yakin bila melihat, mendengar, dan memperoleh informasi secara langsung dari sumbernya. ABSTRACTOne of necessary factors which has influence the increasing rice production is using superior and quality seeds. Itcan increase the frequency of harvesting until three times a year, improve the quality of yield and control the rice plant of pests and diseases. The availability of certified superior seeds for farmers is an absolute requirement, even though in the cost of rice seed production, the proportion of expenditure for seed costs is less than 5% of the total expenses compared to fertilizer (7-14%), land (14-34%), and labor (30-62%). This study is utilizes secondary data.  The objectives of this research is to formulate factors or conditions that cause of using certified seeds hasn't got maximally yet and suitable conditions needed due to absorption of certified seeds can be increase, and adoption technology of superior and certified seed by these farmers can run well. The results of the research showed that there were obstacles that were allegedly able to inhibit the use of certified seed, but only three that could be proven to be true or appropriate while other obstacles could not yet be obtained for compatibility or incompatibility. The three obstacles are: 1) Continuity of the availability of BS source seeds for the basic seed program (BS-FS) has not been guaranteed; 2) Lack of seed breeders; and 3) Formal education, personal experience, and the influence of key figures. Uptake of certified seeds can be increased, among others, if the quality of certified seeds is improved, the adequacy of the availability of certified seeds, the use of certified seeds can increase farmers' productivity and income in real terms. Farmers feel confident when seeing, hearing, and obtaining information directly from the source.

The Indonesian government continuously strives to increase rice production in an effort to meet the staple food needs of almost 270 million people and to turn Indonesia to become a rice exporter country. One of the strategic efforts is to expand the planted area of rice outside irrigated rice areas. Upland is one of the potential areas that continues to be developed to support the increase of national rice production. While upland is not an ideal ecosystem for rice plants to grow, the opportunity to produce rice in this ecosystem is promising, especially using rice as an intercropping in plantation. This effort requires the availability of adaptive varieties to low light intensity conditions. The breeding program to develop shade-tolerant rice varieties has been carried out by the Indonesian Center for Rice Research (ICRR) through the conventional breeding program. Breeding populations were produced by crossing local varieties, national leading varieties and introduced varieties. The selection of shading adaptive lines was carried out using both artificial shading and natural shading in the target plantation areas. New shade tolerant rice varieties have been recently released, namely Rindang 1 Agritan and Rindang 2 Agritan which have the potential to be utilized by farmers for intercropping rice cultivation in the agroforestry systems.

Abstract Rice is the staple food for millions of people of Indonesia which produced from many agroecology including tidal-swamp. The contribution of swampland to the national rice production is still lower than 2%. One of the indigenous knowledge of the tidal-swamp farmers is the massive use of local varieties which have low yield. Therefore, efforts to increase rice production in tidal-swampland of Barito Kuala Regency should consider the use of superior varieties. The purpose of this study was to find out performance of seven superior varieties in tidal-swamp land in two planting seasons. This research was conducted from March 2020 to March 2021 in Karang Buah Village of Belawang District of Barito Kuala Regency, South Kalimantan Province. The research was arranged in two factors of Randomized Complete Block Design namely varieties and seasons. The first factor consisted of seven varieties: Inpari-42 (V1), Inpari-43 (V2), Inpari IR Nutri Zinc (V3), Inpara-8 (V4), Inpara-9 (V5), Inpara-10 (V6), and IR-42 (V7). The second factor, season consisted of season-1 which started from March to July 2020 and season-2 for planting period from November 2020 to March 2021. The result showed that swamp rice varieties had higher value for plant height variables than those of irrigated rice varieties with Inpari-8 as the highest one. However, all irrigated rice varieties performed better which had higher value for panicle number, filled rice grain, and yield with IR-42 as the highest one. All varieties except IR-42 showed higher values of filled grain numbers when cultivated in season-1 supported by good weather during the study.

The development of rice irrigated farming is constrained by the conversion of land agricultural to non-agricultural. Therefore, policy to develop upland rice production in dryland and rainfed lowland is increasingly being implemented. Efforts to expand the application of technological innovations as a lever of upland rice production have intensified by introducing new superior varieties of upland rice. This research aims to analyze farmers' attitudes and satisfaction levels with introducing upland rice to attributes based. The location of this research is in Tegalgiri Village, Nogosari District, Boyolali Regency. Primary data were obtained through a survey method of 35 farmers who planted the Rindang 1, Rindang 2, Inpago 10, and Inpago 12 varieties. Farmer attitudes were analyzed using the Fishbein Multi-attribute Model, while farmer satisfaction level was analyzed using the customer satisfaction index (CSI). The results are the attributes "production" and "resistance to pests and diseases" were agronomic performance which was the most essential and primary consideration for farmers in choosing varieties. Farmers have a positive attitude towards the four new superior varieties. The meaning is that farmers want to adopt and plant the new superior varieties of upland rice. Farmers' satisfaction levels are in the "satisfied" to "very satisfied" category of the four new superior varieties. Hopefully, the new superior upland rice varieties that were introduced can be a choice of varieties by farmers.   Keywords: atributtes, farmer’s attitude, satisfaction level, upland rice, superior varieties

The study reveals the effect of sharecropping on rice productivity in some selected areas of Khulna District in the South-West region of Bangladesh. Access to land for the landless farmer is governed by informal land tenure arrangement, which in turn affects the productivity of the rice farm. In exploring the debate on sharecropping and farm efficiency, the present study has been conducted to assess the effect of sharecropping on rice productivity. During June 2014, a field survey was conducted by using a semi-structured questionnaire in two villages of Khulna District where sharecropping is one of the dominant land tenure arrangements in rice farming. A Cobb-Douglas production function estimation showed that type of land ownership, use of fertilizers, human labor, and modern variety (MV) including hybrid seed and high yielding varieties (HYVs) of seed had the positive and significant influence on rice production. There was a significant mean difference between the sharecroppers and the owner farmers regarding their volume of rice production. The production volume of the owner farmers was significantly higher by around 781 kg ha-1. The study result from the production function revealed that on an average owner farmers’ output was significantly higher by 10% than that of the sharecroppers. The study also observed that higher land rent in form of a fixed amount of cash or a higher crop share demotivated the sharecroppers to supply the optimum level of input and to use the land intensively. The result implied that the sharecroppers are inefficient compared to the landowners. Therefore, it is recommended that sharing an equitable production cost and a justifiable crop sharing structure might be the better options to motivate the sharecropper to become more efficient concerning their volume of production.Bangladesh J.
