Role of Gibberellic Acid, Leaf Extract of Azadirachtaindica and Pongamiapinnata on Growth and Productivity of Garlic

Authors(3) :-Bhosale K. S., Limaye A.S., Shinde B. P.

A pot experiment was carried out to evaluate the effects of foliar application of four different concentrations of GA3 and leaf extract of Azadirachtaindica and Pongamiapinnata on garlic plants. An experiment was carried out with three replications. The growth characteristics e.g. root length, shoot length; number of leaves, fresh weight and dry weight, growth and vigour index etc. were studied. The biochemical contents like chlorophyll a, b and total chlorophylls as well as relative water content contents were studied. The four different concentrations of GA3 were made in absolute alcohol and the dilutions were made in distilled water. For the foliar spray 25 ppm, 50ppm, 75ppm and 100 ppm concentrations of GA3 was used at an interval of 7 days each. The leaf extract of Azadirachtaindica and Pongamiapinnatawas made by crushing 10 g leaves in 100 ml of distilled water and stored in refrigerator separately. The six sets of garlic plants were made with six plants in each set. Among each set of six plants three plants were used as control and three as replicates. The leaves of all the three replicates were sprayed with 25, 50, 75 and 100 ppm of GA3, leaf extract of Azadirachtaindica and Pongamiapinnatarespectively. The first treatment was given after completing the growth for 40 days and the subsequent sprays were given after every seven days. All the plants were watered after every six days. The foliar spray was applied for five times and the plants were used to study the growth parameters after 120 days. Leaf extracts showed comparatively better results than GA3.
