Abstract

Calcium (Ca) is one of the essential macrominerals needed by the human body as a major component in the formation of bones and teeth. Calcium is fulfilled by eating calcium-rich foods, both animal and vegetable. Mustard and lettuce are vegetables that can be a source of Ca. Efforts to increase the Ca content in plants can be done through increasing the concentration of Ca given through fertilizer or in nutrient solution. However, excessive Ca application is not recommended because it will be toxic to plants. This study aims to determine the effect of various Ca concentrations in hydroponic nutrient solutions on the growth and yield of mustard vegetables (Brassica juncea L) and lettuce (Lactuca sativa L.). This study used a floating hydroponic system with a completely randomized design. Treatment of Ca concentrations of hydroponic nutrient solutions that were tried were 0, 100, 200, 300, and 400 ppm. The parameters observed were plant height, number of leaves, level of greenness of leaves, fresh and dry weight, and concentration of calcium in the leaves. The results showed that Ca treatment significantly affected the number of leaves and the level of leaf greenness. Application of 400 ppm Ca in hydroponic nutrient solution is the highest Ca concentration that could increase Ca content in mustard and lettuce plants. Application of Ca 300 ppm is the highest concentration of hydroponic nutrient solution that can increase the Ca content of plants without causing a decrease in plant biomass, and therefore the treatment of Ca 300 ppm can be used for biofortification of Ca by hydroponic in mustard and lettuce plants.

Abstract

Aluminum is prevalent in soils of tidal swamps. Soybean is known to be very sensitive to aluminum stress and so when tidal swamps are converted to soybean cropland, considerable effort and expense are required to overcome Al toxicity in soybean roots. It is therefore necessary to determine at what time in early development soybeans can best endure aluminum stress and identify aluminum-tolerant cultivars. This study was conducted by testing the impact of aluminum exposure on three soybean cultivars (Tanggamus, Karasumame, and M652) (relative to no-exposure controls) at four time periods at 10, 20, and 30 days after planting. No significant effect of aluminum on root growth in the first five days after exposure was observed, but the toxic effects became evident after soybeans had been exposed to aluminum for 10 days. Soybean seedlings that experienced aluminum stress earliest (at 10 days after planting) were more negatively impacted by Al exposure than seedlings exposed later (e.g., 30 days after planting). Root growths of the three cultivars we tested in this study were all detrimentally impacted by aluminum exposure. However, the M652 cultivar was the most sensitive to aluminum exposure. We conclude that the critical threshold period for soybean root growth to succumb to aluminum stress is within the first 30 days after planting, whereas the tolerance to aluminum stress occurs only during the first 10 days of exposure.

Abstract

There is a debate about the effect of the aged biochar on the crop yield. Herein, a field-based experimental data set and analysis provide the information on the effect of the aged biochar coupled with summer legumes on the yield of wheat. During summer 2016, three different legumes (mungbean, sesbania, and cowpea) were grown with the intention of grain for human consumption, green manuring for soil fertility improvement and fodder for livestock consumption. A fallow (control) was also included in the experiment with the purpose of comparison. Biochar was applied to each experimental plot in triplicates at the rate of 0, 5, and 10 tons ha-1. Afterward, the harvesting of legumes, the biomass of the sesbania treatment plot, was mixed in the field, although the biomass of mungbean and cowpea were detached from each respective plot. The wheat crop was grown on the same field layout and design (randomized complete block) of legumes. The data analysis highlighted that significantly maximum grain yield (kg ha-1), biological yield (kg ha-1), thousand-grain weight (g), and straw yield (kg ha-1) were obtained in the plots mixed with sesbania. Regarding the aged biochar effect, maximum yield was obtained in the plots with 10 tons ha-1 treatment. Additionally, the interaction of aged biochar, coupled with legumes, was non-significant. In conclusion, this work could prove that aged biochar, coupled with summer legumes enhanced the yield of wheat on a sustainable basis due to its numerous benefits to the plant system.

Abstract

The genetic studies of individual plants, especially self-pollinated species like chickpea need to be evaluated at the DNA level with the help of molecular markers for identifying genetic variations among the plants. High-quality DNA extraction is a prerequisite for genetic studies. Extraction of intact genomic DNA with high – molecular mass is essential for the study of many molecular biology applications like Polymerase Chain Reaction, endonuclease restriction digestion, southern blot analysis, and also for the construction of a genomic library. Several plant DNA extraction methods are available, even though the DNA isolation methods that give good yield employing both quantity and quality is quite difficult especially for self-pollinated crops like a chickpea. This work was focused on developing a standard protocol for the extraction of genomic DNA and identifying different barcoding markers. The result revealed that the CTAB extraction method with slight modification in protocol had been optimized for DNA isolation. The purified DNA, which was isolated through the CTAB method, had excellent spectral qualities and is efficiently digested by a restriction endonuclease, and is found to be more suitable for long-fragment PCR amplification. DNA barcoding is considered as a promising tool because it provides a practical and standard identification of plants. The isolated DNA sample was processed with a classical DNA barcoding approach by amplifying and sequencing with a universal primer. According to the result, among the different barcoding markers studied, the RbcL and Mat K were found to given the best result for molecular species identification in chickpea.

Abstract

Black cumin (Nigella sativa L) is known as herbal medicine that grows in subtropical regions and spreads from Asia to Europe. Plant parts that are used are seeds that contain bioactive compounds such as thymoquinone and thymol. Information about the growth and production from Indonesia is still limited. Therefore it is necessary to develop efforts to cultivate black cumin in Indonesia, especially in sub-optimal land as initial information in the field of plant adaptation studies. This study aimed to determine the effect of manure on yield components and bioactive content of black cumin in the ultisol lowland of Bengkulu. The study was conducted at Dehasen Bengkulu University research station at an altitude below 100 m above sea level. The accessions of India, Syria, and Kuwait were used at the main plot, whereas media for growing viz cow manure, chicken manure, and without manure as a subplot. The study was conducted in February 2019 using the Split Plot Design with three replications. Observations were made on the components of yields and bioactive levels of seeds. The results showed that the application of chicken manure increased the components of the yield of black cumin seed by parameter number of capsules per plant, number of seeds per capsule, and number of seeds per plant and tended to reduce the weight of 1000 seeds. An increasing level of thymoquinone in the cultivation of black cumin in ultisol lowland of Bengkulu was obtained in the cow manure application. The increased levels of seed thymoquinone were accompanied by decreased levels of thymol for all accession used.
