Abstract:An experiment was carried out to study the “Effect of boron, plant growth regulators and Jeevamrit on fruits drop and cracking of bael (
Aegle marmelos L
.) cv. NB-9 under sodic soil conditions in the year 2019-20 and 2020-21. The experiment was conducted in simple Randomized Block Design having twelve treatments
viz T
1 (Control), T
2 (Boric Acid 0.6%),T
3 (NAA 25ppm), T
4 (GA
3 30ppm), T
5 (BA 250 ppm), T
6 (CPPU 100 ppm), T
7 (Jeevamrit 20%), T
8 (Boric Acid 0.6% + NAA 25ppm), T
9 (Boric Acid 0.6% + GA
3 30ppm), T
10 (Boric Acid 0.6% + BA 250 ppm), T
11 (Boric Acid 0.6% + CPPU 100 ppm), T
12 (Boric Acid 0.6% + Jeevamrit 20%)
Results reveal that all the treatments were found superior over control in aspect like fruit drop, fruit retention and fruit cracking. The minimum fruit drop and maximum fruit retention was found with the treatment of T8 (Boric Acid 0.6% + NAA 25ppm) followed by T3 (NAA 25 ppm) and T11 (Boric Acid 0.6% + CPPU 100 ppm) in both the year of investigation. The minimum fruit cracking was found with the treatment of T11 (Boric Acid 0.6% + CPPU 100 ppm) followed by T12 (Boric acid 0.6% + Jeevaamrit 20%) and T10 (Boric acid 0.6% BA 250 ppm) during both years.
