“…The exact mechanisms behind the effect of mycorrhiza formation, however, remain poorly understood. The positive relationships between phosphorus uptake and seed dry mass have been shown in G. max [223], suggesting that the increased phosphorus influx may prolong seed filling. Speaking of nitrogen-fixing bacteria, the association with Rhizobia was demonstrated to promote seed biomass [224] and viability [225,226] in several legume species, albeit the effect was not retained under drought and temperature stresses [34,227].…”

In flowering plants, seeds serve as organs of both propagation and dispersal. The developing seed passes through several consecutive stages, following a conserved general outline. The overall time needed for a seed to develop, however, may vary both within and between plant species, and these temporal developmental properties remain poorly understood. In the present paper, we summarize the existing data for seed development alterations in dicot plants. For genetic mutations, the reported cases were grouped in respect of the key processes distorted in the mutant specimens. Similar phenotypes arising from the environmental influence, either biotic or abiotic, were also considered. Based on these data, we suggest several general trends of timing alterations and how respective mechanisms might add to the ecological plasticity of the families considered. We also propose that the developmental timing alterations may be perceived as an evolutionary substrate for heterochronic events. Given the current lack of plausible models describing timing control in plant seeds, the presented suggestions might provide certain insights for future studies in this field.

“…Therefore, in the eld a factor of P distribution in the soil should be considered in the model. However, in higher P soils in cultivated soil layers, such as the elds in Japan which have had P fertilizer applied conventionally over long periods of time, the relationship between assimilated and applied P would be indicated only by a constant ceiling line representing soil P without SLOPE in a model even if under diverse applied P conditions (Kakiuchi and Kamiji 2015).…”

Aims This study aimed to model the relationship between assimilated (PA) and applied (PF) phosphorus under diverse nitrogen applications (NF), and to determine the contribution of P to N assimilation (NA) and seed production in soybeans [Glycine max (L.) Merr.], as this has not been done before. Methods Over three years, pot experiments were conducted using nodulated [Lee(+)] and non-nodulated isoline [Lee(–)] soybeans under multiple levels of basal-dressed PF and top-dressed NF from R2 to R7. Results PA in each NF was represented by a function of PF as a straight line with a positive slope and an intercept (PS, soil P) connecting with a ceiling line of constant height. The slope [SLOPE = (PA – PS) / PF], which represented the efficiency of PF usage for PA, asymptotically increased with NF. As a result, PA was represented by a single function of PF × SLOPE, which consisted of slope = 1 and a ceiling across different NF rates. Seed production each year was explained by NA regardless of PA for both nodulation types, although responses of seed yield to PA in Lee(–) differed due to NA. PA asymptotically increased the maximum NA and N fixation by nodulation which were approximated by the N quantitative model. Conclusion PA can be represented as a function of PF by excluding P retained in soils, which is influenced by NF. Accordingly, PA effects seed production via NA behavior determined by fertilizer, soil and fixed N.

Plants can absorb only 30 to 40% of nutrients from the soil through the root system because the absorption process depends on soil properties, wheatear conditions, and the plant’s species. Therefore, foliar fertilization using macro- and micronutrients has proven to be an excellent alternative. Herein, we evaluated the foliar application of a neutralized sulfuric bone meal hydrolysate (NSBMH) on soybean growth parameters, pod yield, nitrogen, phosphorus, and chlorophyll pigment concentrations under greenhouse conditions. A complete randomized block design was performed, and each block contained three treatments: 1% NSBMH, commercial fertilizer, and negative control. After 90 days of growth, soybean plants foliar-sprayed with 1% NSBMH improved significantly (p < 0.05) in terms of foliar area, plant fresh mass, plant dried mass, plant height, nitrogen, and chlorophyll a + b concentrations, while trifoliar leaf number, pod number, and pod fresh and dried masses were higher but not significant, and phosphorus concentration maintained suitable levels when compared to the negative control treatment. Additionally, the 1% NSBMH group presented similar and higher values, but not significant (p > 0.05), on the evaluated traits versus the commercial fertilizer treatment. Consequently, cattle bone recycling for the obtainment of alternative phosphorus as neutralized sulfuric bone meal hydrolysate is an excellent choice because it encourages the reutilization of anthropogenic waste, such as cattle bone waste, which protects the environment and reduces the soil and foliar application of mineral phosphoric fertilizers and reduces dependency on the main unsustainable fertilizer suppliers.
