“…However, treatments of 600 kg N/ha had no further effect on dry biomass of florets and roots and a marginal effect on shoots. These results are in line with the general response of plants to nitrogen (18,19) and specific previous reports indicating that dry matter production is strongly affected by nitrogen fertilization (13,(20)(21)(22). Increase of nitrogen fertilization also resulted in an increase in broccoli yields and fresh biomass (data not presented).…”

Broccoli (Brassica oleracea var. italica) is one of the most important winter season vegetables and a rich source of chemoprotective molecules, including glucosinolates (GSL). The aim of this study was to investigate the impact of nitrogen (N) and sulfur (S) fertilization on GSL concentration and composition in different parts of broccoli plants. A greenhouse experiment was performed, with four different treatments of sulfur (10, 30, 70, and 150 kg/ha) and three treatments of nitrogen (50, 250, and 600 kg/ha). GSL concentrations and plant growth responded to the N supply, but this was not observed above the 250 kg N/ha dose. On the contrary, plant growth did not respond to the S supply, whereas GSL concentrations showed a sharp response to the whole range of S applications (from 10 to 150 kg/ha). Glucosinolate composition was altered differentially in the examined plant parts. Aliphatic GSL were more abundant in the florets and leaves, whereas indolyl GSLs were dominant in roots, in which aromatic GSL were also observed. High nitrogen fertilization had a higher impact on indolyl compared to aliphatic GSLs concentration. More importantly, a high concentration of aliphatic GSL, >2.4 micromol/g dry weight (dw), and high S assimilation into aliphatic GSL were consistently observed in the florets compared to other broccoli parts, indicating adaptable processes for nitrogen and sulfur regarding synthesis and transport of aliphatic GSL for these organs.

“…6). The lack of potato yield response to N fertilizer between 135 and 448 kg ha −1 for other commercial potato cultivars has been reported for Florida (Worthington and Hutchinson, 2006) and for other regions (Alva, 2009; Alva et al, 2009; Feibert et al, 1998; Fontes et al, 2010; Shillito et al, 2009).…”

Nitrogen Fertilizer Rate and Application Timing for Chipping Potato Cultivar Atlantic

Guidelines for N fertilizer management of potato (Solanum tuberosum L.) that include application timing and rates are fundamental to minimize yield reduction risks. The study objectives were to determine the effect of N fertilizer rate, applied at the plant emergence and tuber initiation stages, on N use efficiency and yield of cultivar Atlantic chipping potato. Fertilizer rates of 0, 56, 112, 168 kg ha -1 were applied at plant emergence, and 56 and 112 kg ha -1 were applied at tuber initiation as a side-dress in a factorial randomized complete block design with four replicates in three consecutive years at three commercial farms. All treatments received 56 kg ha -1 of N at pre-plant. Total N fertilizer applied ranged from 112 to 370 kg ha -1 . Applied N rates influenced the levels of soil inorganic N. The maximum daily N uptake occurred between 55 and 70 d after planting, coinciding with the onset of the tuber bulking stage. Potato yield was similar between N rates applied at emergence with the exception of one farm in 2010 due to high precipitation. Average tuber yield ranged from 15 to 33, 29 to 41, and 33 to 39 Mg ha -1 in 2010, 2011, and 2012, respectively. Tuber yield and plant N uptake were similar with N rates above 56 kg ha -1 applied-at tuber initiation. There was an increased residual concentration of soil N at harvest with higher N application; however, this did not correlate to an increase in potato yield. ).Abbreviations: DAP, days after planting; GDD, growing degree days; N emerg. , nitrogen fertilizer applied at plant emergence 16 to 29 days after planting; NHI, nitrogen harvest index; N pre-pl. , N fertilizer applied at pre-plant 34 to 44 days before planting; N tuber init. , nitrogen fertilizer application as side-dress at tuber initiation, 41 to 51 days after planting; NUE, nitrogen use efficiency; NUpE, nitrogen uptake efficiency; NUtE, nitrogen utilization efficiency.

“…In 2011 and 2012, average total yield ranged from 34.3 to 41.4 Mg ha −1 and marketable yield from 30.2 to 35.5 Mg ha −1 with no differences between N emerg and N tuber init treatments. A lack of potato yield response to N fertilizer between 135 and 448 kg ha −1 for other commercial potato cultivars has been reported (Alva et al, 2009; Alva, 2009; Feibert et al, 1998; Fontes et al, 2010; Shillito et al, 2009; Worthington and Hutchinson, 2006).…”

Biomass Accumulation, Marketable Yield, and Quality of Atlantic Potato in Response to Nitrogen

et al. 2015

View full text Add to dashboard Cite

Potato (Solanum tuberosum L.) in Florida is largely produced in sandy soils with low water and nutrient holding capacity, which makes N fertilizer timing and rate key factors for successful crop management. e objective of this study was to determine the e ect of N fertilizer rate and application timing strategy on biomass accumulation, marketable yield, and tuber quality of chipping potato cultivar Atlantic produced in northeastern Florida. Field trials were conducted for three consecutive years on three commercial farms. All plots received 56 kg ha -1 of N before potato planting. Nitrogen fertilizer treatments were 0, 56, 112, or 168 kg ha -1 at plant emergence (N emerg ) combined with 56 or 112 kg ha -1 of N applied as sidedress at tuber initiation (N tuber init ). Aboveground plant biomass showed no response to increasing N at N emerg or N tuber init . Low yield and poor tuber quality were a result of intense rainfall patterns in the rst year. For the other two seasons, marketable yield ranged from 28.7 to 36.1 Mg ha -1 . Nitrogen treatments at emergence were not correlated to an increase in potato yield during the nal 2 yr indicating that under the conditions of these experiments there was no N limitation. Total N applications over 280 kg ha -1 did not increase yield or quality and N tuber init above 56 kg ha -1 had no impact on plant biomass or tuber yield on any farm in any year of this study.
