This article aims to examine the effect of phosphate solubilizing bacteria (PSB) on the growth and yield of G3 seeds of potato (solanum tuberosum L.) varieties of medians. The experiment was conducted in the experimental garden of The Faculty of Agriculture of Winaya Mukti University Tanjungsari, Sumedang with a height of 850 meters above sea level with the order of land Andisol. Time trials are conducted from May to August 2019. The design used is a simple RandomIzed Group Design consisting of five types of phosphate Solubilizing bacteria, namely without PSB, Pseudacidovorax intermedius, Agrobacterium fabrum, Agrobacterium tumefaciens, Serratia nematodiphila and repeated five times each. The results of the experiment showed that the administration of this type of PSB was able to increase the height of the plant and the number of leaves at the age of 28 DAP and 42 DAP and give the result of the number of potatoes and the weight of the perpetak tubers on the potato crop of the medians varieties better.

Experimental research aims to study the interaction between the dose of chicken manure fertilizer and the concentration of biological fertilizer in increasing the yield of zucchini. The research was conducted for three months from March to May 2021 in Sanca Village, Ciater District, Subang Regency. Using a factorial randomized block design method consisting of two factors, the first factor is the dose of chicken manure fertilizer consisting of 4 levels, namely: 0 tons ha-1 (k0), 10 tons ha-1 (k1), 20 tons ha-1 (k2 ) and 30 tonnes ha-1 (k3). The second factor is the concentration of biological fertilizers consisting of 4 levels, namely: 0 ml L-1 (h0), 5 ml L-1 (h1), 10 ml L-1 (h2) and 15 ml L-1 (h3) repeated as many as 2 times. The results showed that the dose of chicken manure fertilizer and the concentration of biological fertilizer did not show any interaction. By independent effect, all levels of treatment with biological fertilizer concentrations did not show significant differences in fruit length, fruit diameter, weight per fruit, fruit weight per plant and fruit weight per plot at harvesting time of 34 DAP, 36 DAP and 38 DAP.

Macadamia nut seeds are orthodox seeds that result in a dormancy period, so breaking the seed dormancy period is necessary. This study aims to determine the effect of drying and water immersion on dormancy breaking and macadamia bean seed germination and which drying and water immersion had the best impact on dormancy breaking and macadamia bean seed germination. The research was conducted in the soil laboratory and screen house of the Faculty of Agriculture, Winaya Mukti University, Tanjungsari District, Sumedang Regency, from June to November 2022. The experimental design used was a simple randomized block design (RBD) with a combination of drying and soaking seeds with nine treatment combinations. Each was repeated three times, so there were 27 experimental units. A = P 40oC + PA 45oC, B = P 45oC + PA 50oC, C = P 50oC + PA 55oC, D = P 50oC + PA 45oC, E = P 40oC + PA 50oC, F = P 45oC + PA 55oC, G = P 45oC + PA 45oC, H = P 40oC + PA 55oC, I = P 50oC + PA 50oC. The results showed that drying and soaking in water treatments at different temperatures had no significant effect on seed moisture content, seed cracking percentage, germination percentage, radicle length, and plumula length.

In order to create future superior varieties, local rice (Oryza sativa L.) is a source of germplasm. In Sumengang Regency, conservation efforts are required to prevent the extinction of native rice genotypes. This study attempts to investigate native rice in Sumedang Regency, identifying morphological characteristics, studying growth and yield, and family links. The study's sites included greenhouses and experimental paddy fields at Winaya Mukti University's Faculty of Agriculture in Tanjungsari, Sumedang Regency, and the Sumedang Regency area. A survey method, descriptive qualitative analysis, and an experimental methodology employing a Randomized Block Design (RBD) with 18 treatments of local rice cultivars and two repetitions were used to conduct the research from May 2022 to December 2022. Sixteen local rice cultivars from Sumedang and two local rice cultivars from Tuban and Probolinggo were discovered as a result of research in the form of exploration; morphological characters were identified using the UPOV criteria (2020); growth characters with high yields were discovered in Gemah and Tri Sakti cultivars, whereas Bagendit cultivars tended to have low growth but high fruitfulness. All 18 of the examined cultivars showed variations in growth and yield. The dendrogram that resulted from the phenetic analysis split the eighteen rice cultivars into two groups: Group I was made up of local rice cultivars, namely Sertani, Bagendit, Masreum, Gading, Jablay, Patenggang, Gede Wangi, Hawara salak, Mentik Susu A, Godang, and Omas Genteng; group II was made up of local rice cultivars, namely Jalur, Gemah, Mesir Super, Sri Dewi, Tri Sakti, Mentik Susu B, and Mareum. There is a 56.16% similarity between each distinct rice variety. Many Sumedang local rice cultivars, such as Gading, Jablay, and Patenggang, share morphological characteristics. The morphological character data shows a 90% similarity coefficient amongst the cultivars.

This study aims to study rice cultivation in Tanjungkerta District with an ethnoagronomic approach based on geographic information systems (GIS). This study was conducted to understand better agricultural cultural patterns, the implementation of agricultural rituals, and their relationship with specific geographical factors. The research was conducted from January 2024 to February 2024 in Tanjungkerta District. The research method involves collecting primary data through field surveys, interviews with farmers, and direct observation of agricultural practices. Geographic data is also collected and analyzed using GIS technology to map rice farming patterns and their relationship with environmental factors. The results of the study show that rice cultivation in Tanjungkerta District has its characteristics, with many traditional practices that are still maintained. The implementation of agricultural ritual culture varies depending on geographical factors, such as the availability of water sources and land topography. This study concludes that geographical factors and local cultural values influence rice cultivation in Tanjungkerta District.

The purpose of this study was to study the interaction between sweet corn varieties and mycorrhizal doses on the growth and yield of sweet corn (Zea mays saccharata Sturt) and to obtain the varieties and mycorrhizal doses that can have the best influence on the growth and yield of sweet maize plants (Zea mays saccharata Sturt). The research was conducted in Bumi Wangi Village, Ciparay District, Bandung Regency, West Java Province, with an altitude of 650 meters above sea level. Average rainfall 2417.40 mm/year Inceptisol soil order with soil pH 6.4. The analysis design uses a linear model of Group Random Design (RAK) of the Factorial pattern, with 2 (two) factors. The first factor is the variety (V), and the second is the mycorrhizal dose (M). Quadratic regression analysis is carried out to find the optimal dose of arbuscular vesicle mycorrhizal (MVA) that can produce the highest/maximum sweet corn variety. The results showed that there was an interaction between Sweet Boy, Paragon, and Scada varieties and the dose of mycorrhiza vesicles arbuscular 10 g plant-1 on the growth and yield of sweet corn (Zea mays saccharate Sturt) and the optimum dose of Sweet boy varieties resulted in a cob weight value with the highest kebobit of 6.04 kg plot-1 with an optimal dose of arbuscular vesicle mycorrhiza of 10.09 g plant-1, the Talenta variety produced a cob weight with a lobe of 5.96 kg plot-1 with an optimal dose of arbuscula vesicle mycorrhiza of 9.84 g plant-1, the Paragon variety produced a cob weight with the highest lobe of 6.05 kg plot-1 with an optimal dose of arbuscula vesicle mycorrhiza of 9.68 g plant-1 and the Secada variety produced a cob weight with the highest petals of 5.85 kg plot-1 with an optimal dose of arbuscula vesicle mycorrhiza of 10.07 g plant-1.
