This ANN was trained to recognize deficiency of N, P, K, Ca or Fe in the bean plants. The ANN is presented as a potential tool for identifying/predicting nutrient deficiencies in bean plants, using records of the fast fluorescence of chlorophyll a ....

Two experiments were conducted to determine some of the problems associated with study of multiple nutrient deficiencies in plants. In the first experiment in which bush beans (Phaseolus vulgaris L. cv. Improved Tendergreen) were grown in solution with no added Fe, no added Mn, or with both ...

Keep in mind that it is normal for plants to lose a few leaves to yellow color that drop off and die. But if you see a whole bunch of them doing it during the vegetative phase than it is something that needs to be fixed. How To Control Nitrogen Deficiencies ...
Nutritional deficiency in plants triggers significant economic losses for important crops. As a direct consequence, it broadly affects plant growth, and photosynthetic efficiency is strongly influenced by nutritional imbalance. To deepen our understanding of how nutritional deficiencies affects photosynthesis,...
This chapter briefly describes the procedure for nutrient analysis in plants, and the symptoms of nutrient (N, P, K, Mg, Ca, S, B, Mn, Fe, Zn, Cu, Cl and Mo) deficiencies in sugarbeet, as well as the chemical and physical properties of soil in which nutrient deficiencies occur.关键...
Plants sense and convey nutrient-deprivation signals to the nucleus. This is a research area of increasing interest, and advances in the knowledge of signal transduction pathways for mineral deficiencies are being made mainly for macronutrients (see [24,25] and references cited therein). However, ...
Definition and methods of calculation of these deficiencies are presented. Improving nutrient use efficiency is essential from economic and environmental point of view. The most important strategies to improve nutrient use efficiency are the use of adequate rate, effective source, timing, and methods ...
