Effect of foliar application of different nutrients on maturity parameters, finger and bunch characteristics and yield of banana cv. grand naine

Abstract

The field experiment was laid out in Randomized Block Design (RBD) with thirteen treatment viz., T0 control, T1 KH2PO4 0.25% + 1% urea, T2 KH2PO4 0.5% + 1% urea, T3 KH2PO4 0.75% + 1% urea, T4 SOP 1.0% + 1% urea, T5 SOP 1.5% + 1% urea, T6 SOP 2.0 % + 1% urea, T7 KNO3 0.5%, T8 KNO3 1.0%, T9 KNO3 1.5%, T10 19:19:19 (1%), T11 19:19:19 (2%) and T12 19:19:19 (3%), with three replications. Observations on maturity and yield attributes of individual treatments were recorded. The results obtained for maturity parameters, fingers characteristics, bunch parameters, yield attributes had significant influence due to foliar application of various nutrients. The treatment T6 i.e. foliar application SOP 2.0% + 1% urea was found significantly superior in yield contributing attributes as compared with other nutrient treatments. The maximum weight of finger (156.00 g), circumference of finger (12.93 cm), length of finger (21.00 cm), weight of bunch (17.66 kg) andyield (78.50 Mt/ha) was recorded in treatment T6 i.e. SOP 2.0 % + 1% urea.
