Response of crossandra (Crossandra infundibuliformis L.) to pruning levels and plant growth regulators

The present investigation entitled “Response of crossandra (Crossandra infundibuliformis) to pruning levels and plant growth regulators” was conducted at Hi-Tech Nursery, College of Horticulture, D.B.S.K.K.V., Dapoli, Dist. Ratnagiri. during the kharif season (2024-25). The experiment was laid out in Split Plot Design (SPD) with sixteen treatment combinations and three replications. Present investigation revealed that, in different pruning levels P1: Pruning at 20 cm above ground level and in case of plant growth regulators T2: GA3 @ 150 ppm was found significantly superior with respect to plant spread, number of branches, number of leaves, Average leaf area, days to initiation of flower spike, days taken for flower opening, days to 50% flowering, duration of flowering, number of spikes per plant, number of flowers per spike, number of flowers per plant, yield of flowers per plant, yield of flowers per plot, yield of flowers per hectare, number of pickings and shelf life. Conclusively, it can be discerned that intensive pruning levels with use of plant growth regulators viz., P1T2 (Pruning at 20 cm above ground level + GA3 @ 150 ppm) had significant effect on vegetative, flowering and yield parameters of Crossandra (Crossandra infundibuliformis).
