Abstract:
The present investigation entitled “Studies on the effect of foliar application of plant growth regulators and macro and micro nutrients on growth and yield attributes of banana (Musa paradisiaca L.) cv. Grand Naine under Agro-climatic condition of Chhattisgarh plain” was carried out during the year 2020-2021 at Research Field of Commercial Tissue Culture Laboratory (CoEAIB), Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) employed in Randomized Block Design having eight treatments, which was replicated three times. The foliar application of micro-nutrient mixture + GA3 300 ppm (T₃) had significant effect and registered maximum plant height (2.23 m), number of leaves (22.84), length of leaves (114.23 cm) and breadth of leaves (58.65 cm) as compared to rest of the treatments under the present trial. The flowering, fruiting and maturity characteristics of banana was significantly influenced under the treatment T₇ (micro-nutrient mixture + potassium di-hydrogen phosphate 1%), which took minimum time to flowering (230.67 days), first fruiting (248.06 days) and overall maturity of banana (320.19 days) under the present experiment. As regard yield and yield attributing parameters i.e. number of fingers per hand (14.59), number of hands per bunch (12.39), length of fingers (19.29 cm), diameter of fingers (13.56 cm), weight of fingers per hand (2.75 kg), weight of individual finger (152.06 g), length of bunch per plant (75.92 cm), weight of bunch per plant (31.07 kg) and yield (72.11 t/ha) were recorded maximum under the superiority of treatment T₇ followed by T₆ as compared to all other treatments.
