“…According to Suresh et al [4], the dry matter accumulation in the plant was attributed to higher supplementation of essential nutrients and phytohormones which results in increased specific leaf weight and improved photosynthesis. Similar results were obtained by Sathishkumar et al [5] by application of TNAU maize maxim which resulted in improvements in growth-related characteristics such as plant height, dry matter production, and the number of tillers mˉ², as well as yield-related characteristics such as the number of productive tillers mˉ², ear head weight, and nutrient uptake by finger millet in comparison with control.…”

A study was carried out in foxtail millet regarding the effect of various foliar treatments in combination with recommended dose of fertilizer on the growth and yield of the crop at Tamil Nadu Agricultural University, Coimbatore during the summer of 2021. Eight treatments in combinations with 100% of the Recommended Dose of Fertilizer (RDF) were arranged in a randomized block design with three replications. Foliar treatments applied were viz., 3% panchagavya along with recommended dose of fertilizer (T1), 3% vermiwash along with recommended dose of fertilizer (T2), 3% TNAU maize maxim along with recommended dose of fertilizer (T3), 1% urea along with recommended dose of fertilizer (T4), 1% KCl along with recommended dose of fertilizer (T5), 0.5% zinc sulphate along with recommended dose of fertilizer (T6), 0.5% iron sulphate along with recommended dose of fertilizer (T7) and recommended dose of fertilizers alone (T8). Each treatment was applied at the active vegetative growth stage and panicle initiation stage of the crop. The application of full dose of fertilizer along with a foliar spray of 3% maize maxim resulted in higher plant height (132.38 cm), number of tillers (2.37), leaf area index (1.37), dry matter production (5937.74 kg/ha), productive tillers per plant (1.95), panicle length (23.59 cm), panicle weight (15.29 g), grain yield (2130.20 kg/ha) and straw yield (4108.14 kg/ha). The plots treated with recommended fertilizer alone had the lowest level of all parameters. Treatments with foliar spray of 3% panchagavya and 3% vermiwash were statistically on par with maize maxim application. The result of the experiment implies that foliar treatment of 3% TNAU maize maxim had a significant effect on growth and yield attributes of foxtail millet.

“…This approach leads to an increase in nutrient concentration in edible parts of plants, through agronomic practices [ 11 , 12 , 13 , 14 ]. Fertilization can be performed through soil and/or foliar application, with this last avoiding fixation and immobilization of nutrients in soils at toxic levels to plants [ 15 , 16 , 17 ]. Indeed, relative to soil application, foliar spraying allows higher efficiency and translocation of nutrients during the productive cycle [ 15 , 16 ], as was observed for chickpeas [ 18 ].…”

One-third of the world’s population is suffering from “hidden hunger” due to micronutrient deficiency. Zinc is acquired through diet, leading its deficiency to the development of disorders such as retarded growth, anorexia, infections, and hypogeusia. Accordingly, this study aimed to develop an agronomic workflow for Zn biofortification on two red winegrapes varieties (cv. Castelão and Syrah) and determine the physicochemical implications for winemaking. Both varieties produced in Setúbal (Portugal) were submitted to four foliar applications of ZnSO4 or ZnO (900 and 1350 g ha−1, respectively), during the production cycle. At harvest, Zn biofortification reached a 4.3- and 2.3-fold increase with ZnO 1350 g ha−1 in Castelão and Syrah, respectively (although, with ZnSO4 1350 g ha−1 both varieties revealed an increase in Zn concentration). On a physiological basis, lower values of NDVI were found in the biofortified grapes, although not reflected in photosynthetic parameters with cv. Syrah shows even a potential benefit with the use of Zn fertilizers. Regarding physical and chemical parameters (density, total soluble solids, dry weight, and color), relative to the control no significant changes in both varieties were observed, being suitable for winemaking. It was concluded that ZnSO4 and ZnO foliar fertilization efficiently increased Zn concentration on both varieties without a negative impact on quality, but cv. Castelão showed a better index of Zn biofortification and pointed to a potentially higher quality for winemaking.

“…Nowadays, it is believed that such fertilization of plants is an important support for nutrient application in the nutrient environment [24,25]. Foliar fertilization is most effective when the soil nutrients are deficient [26]. Foliar fertilization is also important in reducing contamination of the aquatic environment with ions of certain elements, such as nitrogen in aquaponics [27].…”

The foliar feeding of soil-grown plants with essential elements such as molybdate can restore their Nitrate reductase activity. However, the activity of nitrate reductase under the foliar feeding of plants with molybdate and nitrate in hydroponic conditions has not been investigated. Thus, we wanted to investigate the effect of the foliar feeding of molybdate and nitrate on the nitrate reductase activity in the leaves of lemon balm plants under hydroponic conditions. Nitrate and molybdate solutions were applied by spraying the leaves of lemon balm plants and the nitrate reductase activity was determined by the colorimetric method. The results of our study demonstrated that the application of molybdate and KNO3 solution enhanced the nitrate reductase activity in the leaves of lemon balm plants. Importantly, our results indicate that foliar fertilization with nitrate and molybdate can improve nitrogen metabolism and carbon fixation in the leaves of lemon balm plants under hydroponic conditions.
