Abstract

The nutritional state of a plant can range from acute poisoning to acute deficiency. For broad purposes, it could be helpful to categorize the nutritional status into four groups: surplus, ideal, inadequate, and extensive. Nutrients that are considered essential include boron (B), iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), nickel (Ni), molybdenum (Mo), calcium (Ca), magnesium (Mg), sulfur (S), and chlorine (Cl). Every nutrient has an effect on the metabolism of plants at every stage of their growth. Of course, breeding techniques are used to improve the efficiency with which plants take nutrients, such as enhancing nutritional utilization and optimizing nutritional efficiency through root modifications. In nutrient-poor soils, for instance, optimizing root shape to boost nutrient uptake efficiency can boost plant output. While developing organs, particularly reproductive organs, transpire at low rates, they need a lot of mineral resources to expand actively. Plants' nutritional efficiency may be effectively increased by using genetic engineering to transfer genes from other species, so overcoming the restrictions imposed by genetic variation within the same species.

Abstract

Various tropical pulses such as velvet bean, lima bean, and jack bean are leguminous plants that have legumes cultivated and are found in Indonesia. Legumes are a source of vegetable protein with a protein content ranging from 18% to 25%. The aim of study is to evaluate, assess, and identify genotypes of tropical minor legume landraces that show high emergence and vigor through this research, understanding genetic diversity in populations of tropical minor legume landraces can be obtained. This supports efforts to conserve plant genetic diversity, which is important for maintaining long-term food security and ensuring the survival of ecologically and culturally valuable plant species. The research was carried out at the Hydroponic Screen House, Faculty of Agriculture, University of Asahan, from December 2023 to February 2024. This research aims to evaluate the level of emergence or growth and identify genotypes of tropical minor legume landraces that show high emergence and vigor. The data design in this study used Complete Randomized Design (CRD) which was replicated in 3 replications and analyzed using Analysis of Variant (ANOVA) supported by the Tukey test at the 5% level, also to assist in the process of creating diagrams using the Microsoft Excel application in the insert menu, namely pivotTable, and all data analysis used SPSS application, the observed variables include: emergence, germination rate, vigor index, simultancity growth. Based on the Tukey analysis, the highest emergence is K5, P3, K4, B2, K3, B1, B4, P5, and the lowest is B3. The genotypes with the highest germination capacity were P1, P2, K1, K2, P3, P5, B1, B2, while P4, B4, K3, K4, K5, B3, B5 is the genotypes with the lowest values. The genotype with the highest vigor index is B3, P4, while the lowest is B1, P3. The genotypes with the highest growth uniformity were the P1, P2, P5, P3, B1 genotypes, and the lowest were the genotypes P4, B3, B5, K1.

Abstract

Pueraria javanica Bent. is a tropical leguminous ground cover crop commonly planted in oil palm plantations to reduce soil erosion, fix nitrogen, and suppress weed growth. This plant is known to be resistant to fluctuations in low and high light intensity. Pueraria javanica has the ability to induce nodule formation by growing root hairs on the main branched root through a symbiosis with the bacterium Bradyrhizobium japonicum, stimulating the root surface to encourage nodule entry. In addition, legumes have the ability to bind with soil rhizobial bacteria, which fix atmospheric N2. This is a form of N that is not available to plants, but can fix N2 from the soil. The aim of this study was to analyze the effect of variations in sunlight intensity on nodule formation in Pueraria javanica and to determine the effect of sunlight intensity on vegetative growth and morphological development of Pueraria javanica. This research was conducted at the Experimental Garden of Asahan University campus, Asahan Regency, North Sumatra Province, with an altitude of ± 25 meters above sea level from January to March 2025. The research was conducted using a randomized block design method consisting of paranet and IAA auxin treatments. The use of paranet was divided into four levels, namely control without paranet, paranet with transparency of 50%, 75%, and 95%. Meanwhile, the application of IAA auxin consisted of three concentration levels, namely 100 ppm, 200 ppm, and 300 ppm. The observed variables were: plant height, number of leaves, number of leaflets, leaf area, fresh weight of plants, root length, number of root nodules, fresh weight of roots, dry weight of roots. The analysis of significant differences was made using the Tukey's HSD method. All data analysis used the SPSS application version 16.0 (SPSS, Chicago, United States). The results of the study showed that the treatment of various percentages of paranet on Pueraria javanica showed a significant effect on all observation parameters with the best growth in the control treatment. The application of auxin on Pueraria javanica showed a significant difference in the number of leaves, number of leaflets, leaf area, fresh weight of plants, root length, number of root nodules, fresh weight of roots, dry weight of roots. With the best growth in the control treatment. The two treatments above between the treatment of paranet percentage and the administration of auxin showed an interaction that had a significant effect on several parameters observed, including the number of root nodules, fresh weight of roots and dry weight of roots
