| Rapid strawberry multiplication through runners is limited in the acid soils of the tropics and sub-tropics, where short winters and asymmetric weather patterns prevail. In this regard, plant growth regulators particularly GA3 can play a crucial role in on-field runner development. Therefore, the study aimed at finding out the suitable GA3 application strategy for successful runner production in strawberry. Here, GA3 at 0.0 (control), 0.1, 0.5 and 1.0 millimolar (mM) was applied once and twice a week for one and two weeks following factorial randomized complete block design taking three replications. Results revealed that GA3 at 0.5 and 1.0 mM produced maximum number of primary (3.88 plant-1) and secondary (5.04 plant-1) runners, respectively over control (1.43 and 1.62 plant-1, respectively). Notably, total runner counts were the highest in GA3 at 1.0 mM (8.60 plant-1) followed by 0.5 mM concentration (8.11 plant-1). Interestingly, strawberry transplants responded reversely with the GA3 application intensity producing the utmost runners at once a week for one week and two weeks spraying methods (7.73 and 7.61 plant-1, respectively) compared to twice a week for two weeks treatment (4.58 plant-1). Meanwhile in interactions, GA3 at 1.0 mM applied once a week for one week exhibited distinctive superiority over others for runnering (12.97 plant-1) followed by 0.5 mM at once a week for two weeks (10.57 plant-1). Thus, a one-time foliar spray of GA3 at 1.0 mM during the 3rd week of transplanting can be recommended for quick runner production under such challenging environmental situations. | ||
