Effect of Bunch Feeding of Nitrogen (N) and Potassium (K) on Yield Characters in Banana, cv. Barjahaji (Musa AAA Group) under Assam Condition, India

Abstract

The present investigation was carried out at the Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat (India) during March 2015 to June 2016 to know the effect of the application of different nutrient and their combination as bunch feeding on growth and yield of banana. Nitrogen and Potassium were applied in the form of different chemicals along with FYM and compared with control. The experiment was laid out in Randomized Block Design (RBD) with three replications comprising nine treatments. Results revealed that the highest yield of (58.65 t   ha-1), highest finger length (22.28 cm), finger girth (14.10 cm), volume of fingers (254.25 cc), weight of finger (148.73 g), weight of second hand (4.00 kg), and bunch weight (19.00 kg), were observed when the bunch fed with T7 (500 g fresh cow dung + 7.5 g Urea + 7.5 g  K2SO4). However, the highest pulp to peel ratio of 3.40 was recorded in T6 (500 g fresh cow dung + 7.5 g Urea + 7.5 g KCl). Whereas, maximum rind thickness (3.71 mm) was observed in T4 (500 g fresh cow dung + 7.5g K2SO4). The perusal of result revealed that most of the growth, yield, and yield attributes were found highest in treatment receiving 500 g fresh cow dung + 7.5 g Urea + 7.5 g K2SO4. Therefore, treatment T7 (500 g fresh cow dung + 7.5 g Urea + 7.5 g K2SO4) is considered to be the best treatment that can be adopted under field cultivation.
