Pulverização foliar em cafeeiro (Coffea arabica L.) II: aplicação de adubos potássicos
The uptake of potassium fertilizers, namely, KC1, K2S04 and KN03, by beans and coffee leaves was studied in the experiment described herein. The fertilizers were applied as leaf sprays at the rates of 2,25, 4,50 and 9,00 grams, of K20/tree split in 3 applications which were made every week; the proper amount of salts were dissolved in 1 liter of water with wetting agent. Fifteen days after the last application both beans and leaves were sampled for analysis. No leaf injury resulted from the potassium sprays. Leaf -K and bean -K was significantly raised as consequence of the foliar applications of the K- bearing salts.
