We conducted two experiments to determine the usefulness of a chlorophyll content meter (CCM) for the measurement of foliar chlorophyll concentration in sugar maple (Acer saccharum Marsh.) in the fall color period. In Experiment 1, four sugar maple trees were visually assigned to each of four fall foliage color categories in October 1998. On four dates in the fall of 1999, leaves were taken fro...

Relationships of foliar carbon isotope composition (δ(13)C) with foliar C, N, P, K, Ca, Mg contents and their ratios of 219 C3 species leaf samples, obtained in August in 2004 to 2007 from 82 high altitude grassland sites on the Qinghai-Tibet Plateau China, were examined. This was done with reference to the proposition that foliar δ(13)C increases with altitude and separately for the life-form ...

Postemergence application of herbicides can cause phytotoxicity problems in eucalyptus seedlings. Foliar fertilization improve seedling development and mitigate the effects on eucalyptus. Thus, objective this work was to evaluate sensitivity clones subjected applied postemergence associated with foliar fertilizer. For this, a field experiment carried out products indaziflam, clomazone, glyphosa...

Foliar fertilization makes it possible to quickly provide plants with essential nutrients, mainly micronutrients, which can significantly improve the quality of yields. The aim this study was evaluate effect foliar fertilizers containing calcium and microelements on yielding fruit highbush blueberry (Vaccinium corymbosum L.). A two-year carried out in western Poland an experimental production p...

This study wanted to clarify the impact of silicon (Si) fertilization on nutrient uptake, use efficiency, yield and quality rice detect rate mode application Si fertilizer in deficient soil. The field experiment was conducted with ten treatment combinationsof100% NPK,100% NPK + potassium silicate (PS)@ 0.25%,0.50% 1.0% Foliar spray (FS) at tillering stage,100% PS@ 0.25% ,0.50% 1.0%FS panicle in...

The influence of late-season boron (B) application on the bud B concentration and fruit set was studied in sweet cherry (Prunus avium L.). The experiment was carried out on 5-year-old ‘Summit’ and ‘Hedelfinger’ trees on rootstock Gisela 5 in Fruit Growing centre Gačnik. Trees were sprayed with B (1% Bortrack) or water (control). Differences in B concentration were measured between cultivars, th...

18 Experiments to assess the capability of different combinations of Fe-compounds and 19 adjuvants to provide iron (Fe) via foliar application to Fe-deficient plants have been 20 carried out. A total of 80 formulations containing i) one of five Fe-compounds 21 (FeSO4.7H2O, Fe(III)-citrate, Fe(III)-EDTA, Fe(III)-DTPA, Fe(III)-IDHA), ii) a 22 surfactant (Mistol, alkyl-polyglucoside1 or alkyl-poly...
