The present study was conducted to known the response of pruning levels and biofertilizers on flowering attributes and yield of Assam lemon. The experiment was laid out in two factorial randomized block design with three levels of pruning, five levels of biofertilizers and their interaction. The investigation revealed that the pruning 50% length of shoot (P2) was found significantly superior over the control with respect to flowering parameters viz., days required for first flowering (321.93 days), number of flowers per shoot (94.03), duration of flowering (25.13 days) and fruit yield (3.05 kg/plant)and fruit yield (3.39 t/ha). The treatment B4 (Pseudomonas fluorescens @ 90g/plant + Trichoderma @ 90g/plant + Azotobacter @ 15g/plant) performed better with respect to days required for first flowering (315.22 days), number of flowers per shoot (71.44), duration of flowering (27.33 days) and fruit yield (4.10 t/ha). Among the interaction treatments of pruning and biofertilizers, the treatment (P2B4) 50 % pruned plants fed with Pseudomonas fluorescens @ 90g/plant + Trichoderma @ 90g/plant + Azotobacter @ 15g/plant was found significantly superior in response of days required for first flowering (322.33 days), number of flowers per shoot (104.5), duration of flowering (17.67 days) and fruit yield (4.45 t/ha) compare to all the treatment. It can be concluded that efficient management of pruning 50% length of shoot along with biofertilizers combination rather than sole is essential for increase the flowering and yield attributes of Assam lemon.

In conclusion, the present result suggests that the efficient management of pruning along with biofertilizers in an efficient way would not only reduce the sole dependence on chemical fertilizers but also influence the flowering and fruiting of Assam lemon. Among several levels of pruning and biofertilizers application, high pruning (pruning 50% from the terminal portion of shoot) along with combinationof biofertilizers viz., PGPR-Pseudomonas fluorescens @ 90g/plant + Trichoderma @ 90g/plant + Azotobacter @ 15g/plant proved as best in terms of quality production of Assam lemon in this region.
