Abstract:
Standardization of optimum nutrient requirement in banana cv. Ney Poovan (AB) by adopting target yield concept was evaluated for validation of fertilizer adjustment equations. Optimum doses of fertilizers were worked by using fertilizer adjustment equations based on soil nutrient status. The results of the investigation revealed that, the banana cv. Ney Poovan plants applied with 150.75 g N: 17.81 g P: 344.5 g K achieved the highest (33.69 t/ha) but negative yield than expected target yield of 38 t/ha with minimum per cent deviation (-11.35) in plant crop and plants applied with 132.17 g N: 16.02 g P: 377.02 g K achieved the highest (29.96 t/ha) but negative yield than expected target yield of 40 t/ha with minimum per cent deviation (-25.10) in ratoon crop. The maximum TSS, total sugars and reducing sugars were recorded in fruits in T6 (target yield-38 t/ha) in plant crop and ratoon crop. The highest benefit cost ratio of 4.14 and 5.59 respectively recorded in the treatment T6 (target yield-38 t/ha) in plant crop and T7 (target yield-40 t/ha) in ratoon crop.
