“…N deficiency together with adequate P nutrition has been shown to induce excess P uptake by algae (Chu et al, 2013(Chu et al, , 2014(Chu et al, , 2015; Zhu et al, 2015). A similar trend of increased P uptake under Ndeficient conditions has also been reported for spring barley (Nátr et al, 1983), Tef (Eragrostis tef Trotter) (Gashu et al, 2020) and almond trees (Sperling et al, 2019).…”

We assessed the effects of N concentration in the irrigation water on nutrient uptake and distribution in leaves and fruit of mango cv. Keitt grown in a lysimeter for four years. We applied three treatments: N1, no N fertilization (less than 2 mg/L in the tap water); N2, 10 mg/L N; N3, 20 mg/L N. Deficient N conditions (N1) generated low vegetative yield, high fruit:leaf ratio, high photosynthetic activity, high leaf P and K concentrations, and high sugar content along with low acidity in the fruit. Excess N concentration (N3) induced vegetative growth, and reduced fruit yield and gas-exchange characteristics. The calculated annual nitrogen uptake heavily depended on the nitrogen supply (N1-26 g/tree; N2-196 g/tree; N3- 185 g/tree). Fruits were the major N sink being 0.82, 0.26 and 0.05 from the total annual N supplied. The N quantities accumulated in N1 fruits during the reproductive season (May-August), were above the N quantities supplied via fertigation, suggesting that N reserve in the vegetative tissues supplied the fruits high N demand. The finding shows the importance of adequate nitrogen supply to mango trees and the dangers of excessive fertilization.

As fi part of a broader study, two experiments were carried out in growih chambers with three day/might temperature regimes (10'7, 20/14 and 30,'2rC) sttid>ing growth characteristics of individual seedlings over afour-week period. Experiment 1 was performed with spring barley {Hordeum vulgare L.), Gakopsis tetrahit L., and Viola Arvensis Murray. Experiment 2, with three irradiance levels at 20i'14°C, and one irradiance level at the other temperatures, was performed with spring harley, V. arvensis, Chenopodium album L., Brassica rapa L. ssp. oleifera (DC.) Metzger, and Stellaria media (L.) VUl. Leaf area, dry weight, relative growth rate, net assimilation rate, and net piotosynthetic rate generally showed an optinwim at 20/14''C. Increasing inadiaoce resulted in a decreased specific leaf area. Expressed as fraction of shoot dry weight, green leaves decreased and stems, flowers, and yeflow leaves increased with iacreased time, irradiance, and temperature. At all temperatures, barley, B. rapa and G. tetrtdiit had the largest drj' weights, but at 20/14°C C albtm and S. media and at 3OQ1°C C album also had iai^e values. Differences in dry weight between spedes correlated more to morphological features than to assimilation rate.
