Plants were sprayed twice with freshly prepared
solutions of kinetin (20 and 40 ppm), ascorbic acid (100
and 200 ppm) and glutamic acid (100 and 200 ppm), in
addition to the untreated plants (control). Foliar
application of kinetin, ascorbic acid and glutamic acid
were carried out two times of 30 days intervals, starting at
the first week of May at both seasons. Fertilization was
carried out at the rate of 4g/pot calcium super phosphate
(16.0% P2O5), 4g/pot calcium nitrate (15.5% N) and 2g/pot
potassium sulphate (48-50% K2O). The experiment was sit
up in a Completely Randomized Design (CRD) with three
replicates.
