Author(s): R Kumaravel and S Ganesh
Abstract: An investigation was carried out during 2016-2018 at farmer’s field in Ayothiapattinum, Salem district of Tamil Nadu to study the effect of time of pruning and foliar application of organic stimulants on growth, flowering and flower yield of jasmine. The experiment was laid out in split plot design and the treatments were replicated thrice. The main plot treatments (four) are viz. P1 – Pruning during the last week of August, P2 – Pruning during the last week of September, P3 – Pruning during the last week of October and P4 – Pruning during the last week of November. The sub plot treatments (six) are viz. T1- Panchakavya 3%, T2 - Panchakavya 3% + humic acid 0.4%, T3 - Panchakavya 3% + humic acid 0.4% + tender coconut water 5%, T4 - Panchakavya 3% + humic acid 0.4% + moringa leaf extract 5%, T5 - Panchakavya 3% + humic acid 0.4% + tender coconut water 5% + moringa leaf extract 5%. The organic stimulants were applied as foliar spray at 15 days interval from the time of pruning to the flower bud initiation. Data on plant height, number of primary branches, number of secondary branches, total dry matter production, commencement of flowering, number of flowers per plant, weight of single flower bud, weight of flowers per plant and flower yield were observed. The results revealed that the early induction of flowering (46.23 days) and highest flower yield (674.24 kgha-1) were obtained in jasmine bushes pruned during the last week of September along with foliar application of Panchagavya 3% + humic acid 0.4% + tender coconut water 5% + moringa leaf extract 5% during the off season period from November to February.
