Description The present experiment entitled “Effect of salicylic acid and humic acid on flowering, fruiting, yield and quality of mango (Mangifera indica L.) cv. Kesar” was conducted during the year 2012-13 at Regional Horticultural Research Station, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari (Gujarat).
The experiment was laid out with seven treatments in a Randomized Block Design and replicated three times. The treatment combinations comprised of three concentrations of salicylic acid (T2: 1500 ppm, T3: 2000 ppm and T4: 2500 ppm) and three concentrations of humic acid (T5: 0.1 % humic acid, T6: 0.2 % humic acid and T7: 0.3% humic acid) along with control treatment (T1). Both salicylic acid and humic acid were sprayed during the third week of October at flower bud initiation stage. The observations on flowering, fruiting, yield, quality and physiological parameters were recorded and analyzed statistically.
The foliar application of 2000 ppm salicylic acid (T3) recorded maximum number of male and hermaphrodite flowers
per panicle and also the highest hermaphrodite flower to male flower ratio in mango cv. Kesar. The treatment T3 maintained its superiority in producing maximum fruit retention per panicle and number of fruits per tree which was closely followed by treatment T5 (0.1% humic acid). Application of 2000 ppm salicylic acid was also beneficial in enhancing fruit shelf life, fruit quality characters like total soluble solids and reducing sugar and minimizing titrable acidity and physiological loss in weight. On the otherhand, quantitative attributes like fruit length, fruit weight and yield was found higher in trees treated with 0.1 % humic acid (T5). However, the yield remained at par with treatment T3 (2000 ppm salicylic acid).
From the above result, it can be concluded that enhanced flowering and fruit retention, increased yield and production of quality fruits with longer shelf life can be obtained by treating Kesar mango trees with foliar application of 2000 ppm salicylic acid or 0.1 % humic acid.
