Abstract

The present experiment was conducted during 2022–23 and 2023–24 at Horticulture Research Centre, School of Agricultural Sciences, Shri Guru Ram Rai University, Dehradun, Uttarakhand to study the synergistic effects of cincturing and biofertilisers on reproductive growth and yield of litchi on 15-year-old litchi trees. The Experiment was laid out in factorial randomised block design (RBD) with 3 replications comprising 24 treatments. The result obtained from the investigation revealed that among different cincturing levels, C2 (Cincturing level 4 mm width) took fewest days to panicle initiation, days taken to flower initiation and maximum number of fruits/panicles as compared to uncinctured plants whereas C1 (Cincturing level 2 mm width) showed positive response in taking minimum days to bloom. In continuation, the maximum number of fruits/trees was noticed in treatment C3 (Cincturing level 6 mm width). In contrast of this the application of biofertilisers also influenced the flowering and yield parameters of litchi. Biofertilisers treatment B1 (at 150 g/tree) recorded best treatment as it took the minimum days to panicle emergence. Treatment B3 (phosphate-solubilising bacteria (PSB) at 150 g/tree) took minimum days to flower initiation, duration of blooming, number of fruits/panicle whereas, the maximum number of fruits/trees was recorded in treatment B2 (vesicular-arbuscular mycorrhiza (VAM) at 150 g/tree). There was a positive interaction effect was also observed in combined application of cincturing and biofertilisers in which treatment combination C1B1 (CL1 +Azotobacter at 150 g/tree) took the minimum time to panicle initiation in both the years of investigation C1B3 (CL1 +PSB at 150 g/tree) and C4B0(CL4 + control) took minimum time to flower initiation. The C1B0(CL1 +Control) took minimum time for the duration of flowering while C3B3 (CL3+ PSB at150 g/tree) recorded with maximum fruits/panicle.
