    Abstract Farmer fertilization doses are generally insufficient compared to the recommended doses therefore causing low productivity of rice plants. This study aims to evaluate soil nutrient status to determine site-specific fertilization recommendations in Merigi Kelindang District, Central Bengkulu Regency. This study was carried out in February-April 2022 in Merigi Kelindang District, Central Bengkulu Regency, Bengkulu Province. Data was collected by taking composite soil samples at random after harvesting or before the first tillage. Determination of nutrient levels of N, P, K, and soil pH using the at Paddy Soil Test Kit. Data were analyzed descriptively comparatively. The results showed that the nutrient status of paddy fields in Merigi Kelindang District was low N 72%, medium N 14%, high N 7%, and very high 7%. P nutrient status was medium at 93% and low at 7%. High K nutrient status 100%. Meanwhile, pH status is acidic at 7% and slightly acidic at 93%. Recommendations for fertilizer usage in the Merigi Kelindang sub-district as follow; Urea 300 kg/ha for sandy soil (clay content < 20%) or 250 kg in clayey soil (clay content >20%); SP-36 fertilizer (100 kg/ha); KCl (50 kg/ha) without the use of paddy straw as compost and no KCL needed if 5 t/ha paddy straw compost used. Recommendations for soil management with a soil pH value of 5-6 (slightly acidic) are conventional drainage systems and the application of urea as N fertilizer.

    Abstract The Rice Agro-advisory Service which in Indonesian is called “Layanan Konsultasi Padi (LKP)” is an internet-based digital application developed by IRRI to compile recommendations for rice cultivation technology. This study aims to determine the response of farmers in the production centers of irrigated lowland rice in South Bengkulu Regency to the application. The research was carried out from September to November 2022 through a survey involving 87 farmers in 42 villages. The data collected includes farmers’ responses to recommendations for lowland rice cultivation technology generated by LKP and farmers’ responses to its attributes, namely mobility (ease of accessing applications), interactive (recommendations by needs of farmers), communicative (recommendations easily understood by farmers), and autonomous (applications can be operated by farmers independently). Data were analyzed descriptively and correlated using contingency coefficients. The results showed that 83.91% of farmers responded well to the application recommendations. Responses to LKP were classified as good for all attributes as mobility (95.40%), interactive (96.55%), communicative (98.95%), and autonomous (74.71%). Farmers’ responses to the LKP recommendations were positively correlated with the interactive attribute which means that a good response to LKP recommendations is closely related to the needs of farmers for site-specific recommendations for lowland rice cultivation.

    Abstract The rice yield gap (YG) is a global concern, requiring more detailed studies spatially and temporally. As a staple food in Indonesia, rice was produced from 7.4 Mha paddy fields in 2019. Better insight into the YG helps assess measures to boost rice production. However, the information on YG variation among regions scale is limited. This study aimed to identify the rice YG based on 295 historical trial datasets from 23 provinces in Indonesia. We surveyed published trial results from 2012 to 2022 and analyzed YGs, expressed as the percentage of farmer yield (FY). The potential yield (PY) was estimated from field trial results using introduced rice cultivation technology package, whereas FY from results using existing farmer practices. Our study showed that the average YG was 62% in rainfed, 54% in tidal, and 32% in irrigated paddy fields. The YG was significantly high in the paddy fields of Kalimantan (74%) and Maluku-Papua (49%), while the lowest was in Sulawesi (27%) and Java (31%). The YG varied significantly with geo-regions, rice varieties, and cultivation technology packages. Closing the YG and ensuring sustainable rice production requires the implementation of sustainable intensification through applying site-specific technology packages, reallocation of agricultural interventions to a higher YG region, and rice variety improvement to increase PY.

    Paddy Soil Test Kit is one of the appropriate instruments to determine the nutrient status of lowland paddy and preparation of site-specific fertilization recommendations to increase rice productivity. Agriculture extension agents as technology transfer agents have a strategic role. Technical Guidance is needed to improve knowledge of agriculture extension. This study aims to analyze the level of knowledge of agricultural instructors on Technical Guidance use of Paddy Soil Test Kit and Preparation of Site-Specific Fertilization Recommendations. Data collection was carried out before and after implementation of Technical Guidance through direct interviews with a questionnaire guide. The evaluation was carried out on all participants of technical guidance, totaling 32 extension workers from representatives of 11 sub-districts throughout Bengkulu Selatan Regency by providing pretest and posttest to determine the increase in knowledge of Technical Guidance participants. The level of knowledge of participants is calculated using index % formula. The significance of increasing knowledge of technical and technical training participants was analyzed using non-parametric Wilcoxon Match Pairs Test statistical analysis. Correlation test to determine level of knowledge on age, experience, and education. Results of the analysis showed that there was a very significant increase (<0.05) in the knowledge of officers after the implementation of technical guidance from an index of 52.58% (low category) to 84.83% (high category). There is no correlation between increasing knowledge about Paddy Soil Test Kit with age (sig > 0.05) which is 0.571, experience 0.661, and education 0.130.

    Rice is a staple food for the Indonesian people and is a national strategic commodity for national food security. Rainfed area is a potential land to support national rice production, by improving soil management through balanced fertilization based on the soil characteristics. This study aims to determine the soil fertility and alternative management implemented in 2019 and 2020 in Sukaraja and Pondok Kelapa sub districts, Bengkulu Province. Soil fertility status for CEC, base saturation, C-organic, total P and total K taken based on the classification of the value of the combination of these chemical properties. The results showed that the soil fertility status of the rainfed rice fields in Sukaraja and Pondok Kelapa sub districts was low. The limiting factors for soil fertility for Sukaraja sub district are alkaline saturation, total K-total and P-total for Pondok Kelapa sub district. The limiting factors are all elements related to nutrient status assessment, namely CEC, base saturation, total P, total K and C-organic. Alternative soil management is carried out in an integrated manner by providing balanced organic and inorganic fertilizers. The provision of soil amendments such as straw compost, manure, biochar and agricultural lime/dolomite, especially for acid reacting soils, aims at increasing soil fertility before fertilization is applied.

    The objectives of this study was to determine soil fertility and types of plants in understorey ecosystems in oil palm plantation stand which are managed in different ways. The data collection method was a direct observation on smallholder oil palm plantation at 15 years of age with different management, namely: 1) weed control using herbicides, 2) without management, and 3) used for beef cattle grazing. The data consisted of soil fertility and identification of understorey species in each management. The soil samples were taken in a composite manner and analyzed in the laboratory, while the plant species samples were gathered using the 1x1 m2 method and identified using an identification manual. From the results, weed control in oil palm plantation with cattle grazing has a positive impact on soil fertility compared to the use of herbicides and without control. The diversity of understorey species in cattle grazing locations is less, namely, as much as 11 species compared to the use of herbicides (15 species) and without control (22 species). Weed management by grazing cows in the oil palm plantation increased land fertility and the dominance of understorey plants as a source of animal feed.
