Abstract

Development of acid upland in Indonesia still has constraints. To solve the constraint, environmental friendly technology by using organic matter and beneficial microbes is necessary. This study aimed to determine the effectiveness of bio-organic fertilizer formulas for increasing productivity of upland rice plant in acid upland. This study used a randomized block design with 11 treatments using un-treatment as a control and some combination of NPK and bio-organic fertilizer. Each treatment was repeated three times, the size of plot was 5 m x 5 m. Upland rice var. Situ Patenggang was used as a plant indicator, with cultivication spacing of 40 cm x 15 cm. Combination treatment of NPK and bio-organic fertilizer increased population of P-solubilizer and N-fixer bacteria, plant height and tillers. Treatments of NPK-rec, ¾ NPK-rec and combination of ½ NPK-rec, ¾ NPK-rec and NPK-rec with both bio-organic formulas gave the weight of dried unhusked upland rice equal was 1.92 to 2.56 t ha-1 significantly higher compared to the control. The highest RAE was generated by treatment of NPK-rec combined with Bio-Organic Formula II about 137%. Bio-Organic Formula II could increase the growth and productivity of upland rice var. Situ Patenggang and could increase the efficiency udeof ½ NPK fertilizer dosage recommendations or equivalent with 125 kg urea, SP-36 100 kg, and 35 kg KCl ha-1 and increased the dehydrogenase activity.

Abstract

Cassava, an essential staple food with diverse applications, has been relatively underexplored in terms of health analysis using vegetation indices. Conventional field surveys face challenges in covering large areas due to resource constraints. Recent advancements in remote monitoring techniques, such as satellite imagery and Unmanned Aerial Vehicles (UAVs), offer a promising alternative. While satellite imagery enables broad-scale surveys, its limited spatial resolution restricts detailed analyses of individual plants or smaller ecosystems. UAV-based vegetation surveys commonly utilize Vegetation Indices (VI) to assess unique spectral information. This study investigated UAV-based methods for mapping cassava distribution in the Telaga Kahuripan smallholder plantation in Bogor, Indonesia, focusing on UAV imagery, segmentation, and vegetation indices to evaluate cassava plant health at 2, 5, and 8 months of age. The results revealed significant variations in vegetation indices across different cassava plant ages. Particularly, the highest values observed at 5 months of age indicated substantial growth, with NDVI and GNDVI values exhibiting R2 ranging from 0.95 to 0.98, indicating a strong correlation. The robust correlation between NDVI and GNDVI implies that both indices can effectively predict plant health using UAV-based monitoring. Comparisons with existing studies suggest potential variations attributable to factors such as geographical location, environmental conditions, and cultivation practices. Understanding these variations is crucial for refining monitoring techniques and informing agricultural practices. Consequently, the findings have implications for enhancing cassava health monitoring and optimizing agricultural practices to ensure sustainable crop production.

Abstract

 Indonesian strawberry quality is generally still low leading to high strawberry imports. Research aimed to evaluate the effect of Boron (B) and Molybdenum (Mo) applications on the production and quality of strawberries. The research was conducted at a farmer’s field in Rancabali-Bandung, Indonesia, from July to August 2024. Formulated foliar fertilizer containing 500 ppm B and 5 ppm Mo was applied with different concentrations (0%, 0.5%, 0.6%, 0.8%). It was applied at different fruit stages (5 and 12 days after anthesis). Data were evaluated for the number of fruits, fruit size and weight, and fruit quality. Results showed that application time at different fruit ages had no significant effect on all variables. Fertilizer concentration did not affect fruit production, but it affected fruit firmness, TTA, and TSS levels. The concentration of 0.8% resulted in the highest level of firmness, the lowest TAA level (0.32%), and the highest TSS (12.40 oBrix). Thus, the B and Mo applications enhanced some indicators of fruit quality in strawberries. It is important to evaluate the effect of B and Mo applications at the farmer’s level to enhance strawberry quality.  Keywords: Acidity, Brix, foliar fertilizer, production, vitamin C

Abstract

This study aims to identify the morphological characteristics of 17 taro genotypes. The research involved the inventory and morphological identification of taro genotypes in Bogor, West Java Province, and Ponorogo, East Java Province. The morphological description of taro followed the guidelines in the IPGRI descriptor book. Analysis of variance (ANOVA) was used to examine quantitative data. Using the 22-0 version of SPSS Software, Duncan’s multiple range test was employed at a 5% significance level to determine whether the variables observed had a significant effect. A cladogram was created to evaluate the degree of similarity between the taro genotypes based on the collected data. Fourteen genotypes of Colacasia have been identified, consisting of 7 Eddoe types: Satoimo, Ozikawa, Siromi, Jepang Ungu, Dempel, and Dempel Ungu, 7 Dasheen types including Bentul Ungu, Ketan, Pratama, California, Sutra, Pari, and Bentul, while 3 Xanthosoma including Talas hitam, Talas HIjau, and Talas Kuning. The results showed that the highest association coefficient values were found in Pratama with California, Bentul Ungu with Ketan, and Ozikawa with Siromi. The genotypic variance coefficients were high for characters associated with taro's growth and yield, including corm weight, cormel diameter, cormel weight, and plant span.

Abstract

Urban agriculture is a permanent and dynamic part of urban socio-economic and ecological systems. It uses typical urban resources, competes with other urban functions for land and water, is influenced by urban policies and plans, and contributes to urban social and economic development. To assess agricultural sustainability and predict future food security, it is essential to understand the relationship between farming systems and biodiversity. The research aimed to assess biodiversity risk in urban agriculture. This research employed a mixed-methods approach, combining quantitative and qualitative methods, and incorporated a field survey that involved collecting data from research and literature reviews. The field survey involved collecting data from research questionnaires distributed to respondents to determine their perceptions of biodiversity risks to flora and fauna resulting from urban agricultural activities. The results of the study showed that the p-value was greater than the alpha level (α = 0.05), indicating that urban agriculture in East Jakarta does not significantly affect biodiversity risks of flora and fauna.
