Abstract
Purpose: Using plant growth regulators (PGR) and nutrients in a standard way can help plants grow better. That's why we did this experiment to see how PGR and NPK fertilizer affected the growth, yield, and quality of baby corn. Research method: The split plot experiment employed plant growth regulator in the main plot and NPK fertilizer in the subplot. The test had four different PGRs: control (P1), mepiquat chloride 200 ppm (P2), naphthalene acetic acid (NAA) 40 ppm (P3), and gibberellic acid (GA3) 100 ppm (P4). It also had four different NPK (Urea-TSP-MoP) fertilizer levels: 150-90-75 (F1), 180-105-90 (F2), 210-120-105 (F3), and 240-135-120 (F4) kg ha-1. Findings: From the results, the interaction effect showed that P4 in combination with F4 produced the highest yield parameters, including cob length with husk (23.11 cm), diameter with husk (3.46 cm), diameter without husk (2.95 cm), weight without husk (55.29 g), cob plant-1 (3.67), and yield without husk (4.41 t ha-1). The maximum starch (8.15%) was achieved when P2 was combined with F4, while the maximum protein (5.56%) was gained when P2 was combined with F3. Research limitations: The experiment is conducted in a single season and single location, hence multilocation and multi-years’ trial should be conducted before recommending these results to the farmers. Originality/Value: Based on the results it can be conclude that spraying GA3 100 ppm along with NPK fertilizer (240–135–120 kg ha-1) is thought to be a good way to improve baby corn growth, yield, and quality.
