Abstract

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.

Abstract

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.

Abstract

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.

Abstract

Sweet corn production in Indonesia has increased from 2015 by 19.83 million tons and increased to 23.16 million tons in 2016 (Ministry of Agriculture, 2020). Sweet corn production in Indonesia is low, with an average yield of around 8.31 t ha-1 (Garate, 2017). NPK fertilizer is one of the technologies in the agricultural business that facilitates farmers in applying plant nutrition because NPK fertilizer contains more than one type of nutrient. (Trichoderma sp is a microorganism or biological agent that can improve soil's physical, chemical, and biological properties. Trichoderma fungi make the soil structure loose, making it easier for roots to absorb nutrients, especially phosphate (P), and increase microbial activity. Trichoderma sp is a decomposer (decomposing species) and plant stimulator. The research method used is Randomized Group Design (RAK). The first factor is the application of NPK Phnska Plus fertilizer, and the second factor is the dose of Trichoderma sp. and the quadratic regression analysis test. There is an interaction effect between the dose of NPK fertilizer and the dose of Trichoderma on all parameters observed. NPK fertilizer dose of 6 grams/plant (P2) and Trichoderma dose of 20 grams/plant produced significant weight compared to other treatments. 45% of the variance of the treatment variable of NPK fertilizer dose and Trichoderma dose has not been able to explain the independent variable.
