Abstract: Phenological studies are important for understanding the influence of weather dynamics on vegetative growth, flowering and fruiting on mango. BBCH (Biologische Bundesantalt, Bundessortenamt and Chemische Industrie) scale was used for data recording and to assess utility of the scale in mango phenological studies. Phenological stages of the mango were recorded at weekly intervals on 60 shoots of cultivar Totapuri at five diverse locations for testing usefulness of scale under different diverse ecologies and data from one location, i.e., Lucknow (26o 54' N and 80o 48' E ) was used for analysis. Existing BBCH scale was modified on the basis of data recorded for mango in which seven out of 10 principal stages were used, starting with bud development (stage 0) and ending with maturity of fruit (stage 8). Three digit scale was used for inclusion of the mesostages between the principal and secondary growth stages. Highly recurring flowering phenophases were 511 (18 %), 513 (20 %) recorded in standard week 9 and 517 (45 %) in standard week 11 (March). Other important phenophases, 619 (38 %) and 709 (10 %) occured during standard weeks 13 and 22 to 23, respectively. A high degree of variation in shoots representing principal growth stages viz., vegetative bud, leaf and shoot development was observed due to simultaneous transition of the stages during standard week 33 to 42 and 4 to 24. Limitations of existing BBCH scale and comprehended modifications have been proposed and discussed. The study revealed that the extended BBCH-scale for mango can be widely used because of its utility in describing all phenophases pertaining to bud, shoot, leaf, panicle and fruit development and indicated the incisive growth pattern of the shoots and seasonal variation. This is the first report on quantitative analysis of mango phenological data using BBCH scale.
