BACKGROUND: Rabbiteye blueberry(Vaccinium asheiReade) has low nutrient uptake efficiency due to its shallow and fibrous root system without root hairs. This study was carried out to establish an efficient nutrient application standard by investigating the effect of nitrogen fertigation on the growth and fruit characteristics of rabbiteye blueberry. METHODS AND RESULTS: 'Brightwell' rabbiteye blueberry was treated with 0, 50, 100 and 200% nitrogen fertigation of recommended fertilizer application (6, 9 and 14 g/bush in the first, second and third years, respectively). The results showed that leaf nitrogen content significantly correlated with the fruit weight and fruit yield. However, canopy area, dry weight, sugar and anthocyanin contents did not correlate significantly with the leaf nitrogen content. The leaf and stem dry weights of 'Brightwell' rabbiteye blueberry during the third year of planting were the highest with 50% nitrogen fertigation (leaf dry weight=723.7 g/bush; stem dry weight=890.7 g/bush). Maximum fruit yield of 'Brightwell' rabbiteye blueberry (12.9 kg/bush) was observed during the third year of planting with 50% nitrogen fertigation and this was about 70% greater than the treatment that received no nitrogen fertigation. The fruit yields of 'Brightwell' rabbiteye blueberry during the third year of planting treated with 100 and 200% nitrogen fertigation were 11.0 and 11.5 kg/bush, and these were 17 and 12% lower than the 50% nitrogen fertigation treatment, respectively. Further, the efficiency of nitrogen utilization was the highest (90%) with 50% nitrogen fertigation and lowest (18%) with 200% nitrogen fertigation. CONCLUSION:The results of this study suggests that fertigation with 50% of the recommended fertilizer could be most effective for enhancing the growth and nitrogen use efficiency of rabbiteye blueberry.

“…There are observations, e.g. by BHAT(1983), that NO3 and NH4 affect specificly the root morphology, roots fed by NO3 being long and slender whereas roots fed by NH4 are short and thick. As part of several comprehensive experiments to investigate the morphogenetic effects of "N" in soil on roots of cultivated plants, the response to several different mineral Ncompounds was investigated (KRUTZFELDT 1979).…”

Morphogenetic Effects of Different Mineral N‐compounds on Roots of Maize (Zea mays L.), Spring Barley (Hordeum vulgare L.) and Broad Bean (Vicia faba L.)

Plants of maize (Zea mays L.), spring barley (Hordeum vulgare L.) and broad bean (Vicia faba L.) were raised in tubes filled with a soil‐sand mixture and supplied with nutrient solution. The nutrient supply was varied with regard to concentration and typ of compound of “N”. Due to the relatively high concentrations of “N”, dry matter of shoots and roots was reduced in comparison to the control; root morphology was affected in terms of root length and root thickness. The N‐compounds, used in the experiment, exerted quantitatively different influences on dry matter production and root morphology, NH4NO3 being the N‐form which had the weakest detrimental effects. There was no specific response to NH+4 or NO−3 but a strong influence could be shown for NH4Cl and NaNO3. Probably not only the concentration of “N” and the form of “N” have a specific influence, but also the cations and anions associated with the N‐containing ion are effective.
