“…Tabatabaei et al 30 reported that a high concentration of NH 4 + inhibited photosynthesis, growth, and yield in strawberry, and a high ratio of NH 4 + to NO 3 − has been shown to reduce the biomass allocation to vegetative plant parts. 31 In accordance with this, a larger proportion of total plant DM accumulated in fruit from the organic treatments despite a lower fruit yield in three of the four organic combinations compared with inorganic fertigation (Figure 2).…”

“…High K + /Ca 2+ and K + /Mg 2+ ratios in the fertigation solution reduce fruit number, fruit weight, and yield in strawberries. 38 Also, the high levels of NH 4 + in the root zone may have competed with Ca 2+ , Mg 2+ , and K + during root uptake and resulted in lower leaf concentrations of Ca, Mg, and K and lower fruit concentrations of Ca and K. 31 Nutrient Deficiency. Low levels of available N and P in the root zone, especially at the end of the fruiting period, could also have caused the reduced fruit yield and fruit weight when plants were supplied with organic fertilizer.…”

Four combinations of two solid organic fertilizers (Monterra Malt and chicken manure) applied before planting and two liquid organic fertilizers (broad bean and Pioner Hi-Fruit/K-Max) given through drip irrigation (fertigation) were compared with inorganic fertilization regarding growth, yield, nutrient concentration, and fruit quality of strawberries. Broad bean fertigation combined with Monterra Malt resulted in a similar fruit yield as inorganic fertilizer and a higher yield than Monterra Malt combined with Pioner; however, total soluble solids, firmness, and titratable acid were improved with Pioner fertigation, although these parameters were more affected by harvest time than the applied fertilizers. The concentrations of most nutrients in fruits and leaves were higher in inorganically fertigated plants. The reductions in fruit yield in three of four treatments and fruit weight in all organic treatments may be due to a combination of the following conditions in the root zone: (1) high pH and high NH4(+)/NO3(-) ratio; (2) high EC and/or high NaCl concentration; (3) cation imbalance; and (4) nutrient deficiency.

“…The reduction in accumulation of these cations in plants grown under high ammoniacal N was also observed by others author in Fragaria spp. (Choi et al, 2011), Eustoma grandiflorum (Mendoza-Villarreal et al, 2015), Sorghum bicolor (Chen et al, 2016), and B. oleracea (Barreto et al, 2017). The nutrient imbalance observed in the ammoniacal system is due to the antagonism effect between NH4 + and the other cations, as they compete for the same Means followed by different lower-case letters indicate Si significant effect within NH4 + and NO3 -ratios and uppercase letters indicate NH4 + and NO3 -ratios significant effect within Si concentrations, according to Tukey's test (P ≤ 0.05).…”

Ammonium (NH4 +) toxicity in yellow passionfruit (Passiflora edulis Sims f. flavicarpa O. Deg.) may be mitigated by Si application. This study aimed to evaluate the interaction effect of Si and high level of NH4 + on yellow passionfruit seedlings nutrition, physiology, growth, and DM production. Pots were filled with pinus bark and nutrition solution was applied. Treatments were arranged in a completely randomized design, with five replicates, in a 2 × 2 factorial scheme: two ratios of NH4 + and nitrate, NO3 + (40/60%, without high level of NH4 + ; and 75/25%, with high level of NH4 +) at N concentration of 13 mmol N L-1 , in the absence and presence of Si (2.0 mmol L-1). Sixty days after seedling transplant it was evaluated: N, Si, K, Ca and Mg root and shoots accumulation, leaf green color index (GCI), electrolyte leakage index (ELI), intracellular CO2 concentration (Ci), transpiration rate (Tr), stomatal conductance (gs), net photosynthesis rate (Pn), stem diameter, leaf area, root length, N use efficiency (NUE) and root and shoot DM content. Plants cultivated with Si had 19.1% and 16.3% lower Tr and gs, respectively, regardless NH4 + concentration. Moreover, Ci and Pn were 13.2% and 16.4%, respectively, higher in plants that received Si. Plants cultivated under high NH4 + concentrations, with Si application had 17% bigger stem diameter and 15.4% bigger root length than plants without Si application. Si application in yellow passionfruit seedlings cultivated with high level of NH4 + increased accumulation and NUE, root length, root DM, and GCI. In addition, Si application reduced ELI, which resulted in higher stem diameter. These results prove that Si application mitigates NH4 + toxicity in yellow passionfruit seedlings.

“…+ en las soluciones nutritivas formuladas con NO 3 -, Lorenzo et al (2000) encontraron en rosa bajo hidroponía una mayor tasa de absorción de N durante la elongación del tallo y comportamiento similar en la absorción de K, mientras que la concentración de P aumenta solo en las raíces de las plantas. Choi et al (2011) Terraza et al (2012) encontraron 0,59% de Mg foliar, significativamente menor que en los tratamientos con relaciones 100:0 y 85:15, con 1,07 y 1,05%, respectivamente, de Mg foliar. Para Abasi et al (2016) las concentraciones de N en bulbo y de Ca, Mg y K en la parte aérea del tulipán se vieron significativamente afectadas por la fuente de N. En general, en las plantas fertilizadas con NH 4 + se observaron concentraciones más bajas de los cuatro elementos, con 0,84, 1,10, 0,80 y 0,53%, respectivamente.…”

Una alternativa a la lixiviación de nitrógeno en el cultivo de flores de corte es la optimización de la fórmula de fertirriego. Con el objetivo de estudiar la reducción de nitrógeno y el aumento de la proporción de amonio en la relación NH4+:NO3-, se evaluaron en condiciones de invernadero dos concentraciones de nitrógeno total (200-140 mg L-1 en fase vegetativa y 160-112 mg L-1 en fase productiva) y tres relaciones de NH4:NO3- (5:95, 15:85 y 25:75) en clavel estándar cv. Don Pedro sembrado en sustrato. Se determinaron en tres momentos de cultivo los contenidos elementales del tejido vegetal, el pH y la concentración de nitrato en los lixiviados. Se observó mayores concentraciones de Zn y Cu en el tejido vegetal con la disminución de N total; así mismo, se obtuvieron incrementos de N y Zn y disminución de Mg con el incremento NH4+, que, a su vez, disminuyó el pH en el sustrato. La disminución de N total no afectó significativamente el contenido de N en el tejido de la planta, pero si el contenido de NO3- y N total en el lixiviado.
