Abstract
In addition to essential inorganic nutrients, plants may need other organic substances as they have grown in soil.
The capacity of micro-organisms to synthesize biotic substances in a soil has been for a long time.
Of these substances, a B-group of vitamins (Thiamine, Nicotinic acid, and Pyridoxine) and amino acid (cysteine) were selected as good source of nutrition for the plants.
The capacity of micro-organisms to synthesize biotic substances in a soil has been for a long time.
Of these substances, a B-group of vitamins (Thiamine, Nicotinic acid, and Pyridoxine) and amino acid (cysteine) were selected as good source of nutrition for the plants.
Present paper shows the effect of the addition of a mixture of these organic substances and iron to the nutrient solution on the growth and nutrient uptake in cut-flower chrysanthemum in the nutrient film technique system.
A mixture of these substances added to the basal nutrient solution had a marked effect upon the growth and uptake of inorganic nutrients in chrysanthemum plant.
Leaf green color was intensified by the treatment of liquid fertilizer containing thiamine, iron, and cysteine.
As a side effect, these substances gave resistance of plants to unfavorable conditions.
