“…This study was conducted in conjunction with the above-mentioned study to determine the effects of the sprayer system and micro-nutrient foliar treatments on mineral concentrations in young and mature foliage. This study involved two sprayer systems (magnetic and non-magnetic) and three chelated iron fertilizer rates (5,10,and 15% Fe). All fertilizer treatments were applied at the same rates and methods mentioned above to maintain the same conditions as the first study.…”

A greenhouse study was conducted to determine the effects of foliar applications of magnetized, chelated liquid iron fertilizer for increasing the drought tolerance of two legumes. Study objectives were to determine the drought tolerance effects of four treatments on foliar gas exchange, soil moisture, and plant growth for velvet bean (Mucuns pruriens) and soybean (Gylcine max) plants. The four foliage treatments included applications with chelated liquid iron fertilizer (2.5 and 5%) with a conventional boom sprayer, with and without magnets in the spray lines. Physiological measurements were collected before foliar treatments and again after a 24-day deficit irrigation schedule. Physicochemical water properties were measured for each of the foliar treatments. Photosynthesis rates were 5.98, 2.04 and 3.19 µmol/m2/s for the control, non-magnetized and magnetized fertilizer treatments (2.5%), respectively, after completing the deficit irrigation schedule. Instantaneous water use efficiency (IWUE) was 0.60, 0.28 and 1.02 for the control, non-magnetized and magnetized fertilizer treatments (2.5%), respectively, after completing the deficit irrigation schedule. Photosynthesis and IWUE increased 56 and 263% for the magnetized fertilizer treatment (2.5%) compared to the non-magnetized foliar treatment, when averaged across both legume species. Photosynthesis and IWUE increased as electrical conductivity increased and oxidation reduction potential (ORP) decreased in absolute terms. A single foliar application resulted in aberrant physiological responses that are contrary to very widely held plant defense theories involving abiotic stressors. The single application improved the photosynthesis and water use efficiency for water stressed legumes emphasizing the need to better understand the relationships between water quality, plant bioenergetics, and stress physiology. Improved drought tolerance in row crops such as dry beans and soybeans, with a single magnetized fertilizer application, would be cost effective and easily adapted into current cropping systems. Interactions among physicochemical water properties, bioenergetics, plant metabolism, and crop stress physiology need to be further investigated in order to improve the quality of irrigation water to enhance drought tolerance of field crops.

“…Drought stress may be partially alleviated with micro-nutrient applications [5][6][7]. Iron (Fe) is a micro-nutrient that is utilized by legumes in several key nitrogenase enzymes, and for ferredoxin which is an electron carrier [5][6]. Legumes also utilize iron in the synthesis of heme in hemoglobin and for nodule formation.…”

“…In plants, Fe and Co are indispensable elements and especially important for legume species such as soybean, to sustain plant development, nodule production, and nitrogen fixation [6,52]. The availability of these elements was necessary for enhancing or preparing plants to better tolerate drought stress [7,[53][54][55][56]. The effect of Fe NP has also been investigated in cowpea [57], but this is the first report related to NP-induced drought tolerance in soybean.…”

“…To overcome this challenge, alternative breeding and biotechnological approaches, such as micronutrient modification, have been extensively studied [3][4][5][6]. The supplementation of mineral microelements, such as iron, copper, cobalt, magnesium, manganese, nickel, and zinc, is known to increase the crop yield, especially under adverse environmental conditions [7,8].…”

Drought is a major abiotic stress that negatively impacts plant growth and crop production. Among various techniques used to alleviate drought stress in plants, nanoparticle application is considered to be effective and promising. In this study, the responses of plants treated with iron, copper, cobalt, and zinc oxide nanoparticles (NPs) were analyzed in soybean under drought-induced conditions. The obtained results indicated that these metal-based NPs supported the drought tolerance of NP-treated plants. The desired physiological traits, viz., relative water content, drought tolerance index, and biomass reduction rate, were significantly improved, especially in iron NP-treated plants. At the molecular level, quantitative PCR analysis of several drought-responsive genes revealed a gene-, tissue-, and NP-dependent upregulation of gene expression. Iron NP treatment promoted the expression of all tested genes in roots; additionally, the expression of three drought-responsive genes increased in leaves of all NP-treated plants, while the expression of GmERD1 (Early Responsive to Dehydration 1) was induced in both roots and shoots under the four NP treatments tested. Our findings suggest that NP application can improve drought tolerance of soybean plants by triggering drought-associated gene expression.

In visual observations focused on emergency service facilities in several building locations, it was found that several emergency service facilities were not available. In addition, the facility also does not meet the provisions so it is categorized in an unsafe condition. From these conditions, it is necessary to know the safety factor for the comfort and security of the building. This study aims to determine the safety factor and several other factors that affect safety in buildings. It is necessary to determine the critical factors that have a very high influence and, the strategies needed in planning, construction, and operations. This research uses qualitative and quantitative methods with SPSS and Smart PLS tools. A total of 20 questionnaires were given to respondents to get their opinion on the critical factors needed. The purpose of this research is to increase the knowledge base, especially in the field of developing school building safety standards in West Sumatra - Indonesia. The findings of this study are in the form of technical operation & maintenance factors that are influenced by systematic information systems and programs. In addition, safety factors are strongly influenced by building services, external environment, and operational & technical maintenance.
