EFFECT OF DIFFERENT CHEMICALS ON LEAF SHEDDING OF POMEGRANATE ‘BHAGWA’

The present investigation on effect of different chemicals on leaf shedding of pomegranate ‘Bhagwa’ was laid out in a randomized block design with five replications and four treatments i.e., ethrel at 2.0 ml/L, thiourea + di-ammonium phosphate at 10 g/L, propenophos at 5 ml/L and control (water spray). Treatments were given 20 days before the start of bahar.
The data revealed that early leaf shedding (6.60 days) was observed due to spraying of ethrel at 2 ml/L and was statistically at par with spray of thiourea + di-ammonium phosphate (10 g/L of water each) and propenophos (5 ml/L) 6.80 and 7.00 days, respectively.
Maximum number of female flowers were observed in ethrel treatment (95.40). Maximum fruit set was observed in ethrel spraying treatment (71.00%). The number of fruits/tree (94.95), average weight of fruit (263.74 g) and yield (25.05 kg/tree) were found highest due to spraying of ethrel (2 ml/L). The fruit sample of ethrel at 2 ml/L and propenophos at 5 ml/L treatments analysed from pesticide residue point of view revealed that the treatment ethrel at 2ml did not show any detectable level of residue in harvested fruits, whereas, the treatment of propenophos at the time of leaf shedding showed detectable level which is below maximum residue level.
