“…Different plant species exhibit varying degrees of tolerance to phosphorus toxicity. Some species are highly sensitive and may show severe symptoms, even with relatively low levels of phosphorus, while others are more tolerant and can withstand higher concentrations of phosphorus without significant damage [ 206 ].…”

Plants being sessile are exposed to different environmental challenges and consequent stresses associated with them. With the prerequisite of minerals for growth and development, they coordinate their mobilization from the soil through their roots. Phosphorus (P) and iron (Fe) are macro- and micronutrient; P serves as an important component of biological macromolecules, besides driving major cellular processes, including photosynthesis and respiration, and Fe performs the function as a cofactor for enzymes of vital metabolic pathways. These minerals help in maintaining plant vigor via alterations in the pH, nutrient content, release of exudates at the root surface, changing dynamics of root microbial population, and modulation of the activity of redox enzymes. Despite this, their low solubility and relative immobilization in soil make them inaccessible for utilization by plants. Moreover, plants have evolved distinct mechanisms to cope with these stresses and coregulate the levels of minerals (Fe, P, etc.) toward the maintenance of homeostasis. The present study aims at examining the uptake mechanisms of Fe and P, and their translocation, storage, and role in executing different cellular processes in plants. It also summarizes the toxicological aspects of these minerals in terms of their effects on germination, nutrient uptake, plant–water relationship, and overall yield. Considered as an important and indispensable component of sustainable agriculture, a separate section covers the current knowledge on the cross-talk between Fe and P and integrates complete and balanced information of their effect on plant hormone levels.

“…For example, up to 50% of the soil-applied N [22], about 70% of the soil-applied P [23] and as reported by [24], more or less 60% of the total applied S may be lost due to one or more of these reasons. Among mineral nutrients, P is an essential nutrient and an integral component of several important compounds, including adenosine triphosphate and other related high energy compounds, all sugar-phosphates in photosynthesis, co-enzymes, glycerol phosphatides, nucleic acids, nicotinamide adenine dinucleotide, nicotinamide adenine dinucleotide phosphate, phospholipids and phosphoglycerides [25].…”

An experiment was carried out with an aim to enhance the performance of chickpea by the spray of a small quantity of phosphorus (P) and/or sulphur (S) with or without the soaking of GA treatment (10 -6 M GA for 8h) and/ or the GA spray treatment (10 -6 M GA at 60-70 DAS). P and S each at 2 kg/ha were sprayed in two equal splits i.e. half at 60 and the remaining half at the 70 DAS alone or in combination with the GA treatment. Prior to sowing, total seeds of chickpea were grouped into two; one group of seeds was soaked in 0M GA (control) and the other group were soaked in 10 -6 M GA aqueous solution, each for 8 hours. There were total sixteen treatments with ten combinations of P and/or S with GA are possible viz., F PS , S GA + F P , S GA + F S , S GA + F PS , F GAP , F GAS , F GAPS, S GA + F GAP , S GA + F GAS and S GA +F GAPS . The combined application of P and S with GA showed better responses and further improvement in carbonic anhydrase (CA) activity, stomatal conductance (gs), net photosynthetic rate (P N ), nitrate reductase activity (NR), and leghemoglobin content (Lb) at two sampling stages (90 and 100 DAS). This treatment also increased pod number per plant, seed yield per plant and harvest index (HI), seed protein and carbohydrate content at harvest. This combination augmented the protein content (21%), carbohydrate content (11%), seed yield (86%) and HI (91.78%).
