Abstract

Banana cv. "Njalipoovan" (Musa AB group, Syn. Ney Poovan) is one of the popular varieties cultivated in the homesteads of Kerala. This variety has high export potential due to its edible and keeping quality. Eventhough fertilizer requirement was worked out for different varieties; no attempt has been made to standardize the nutrient requirement of banana cv. "Njalippovan", especially in the loamy sand soils of Onattukara. Field experiments were conducted for two years (1998-2000) at Onattukara Regional Agricultural Research Station, Kayamkulam to study the influence of three levels each of N (100, 200 and 300 g plant-1), P2O5 (100, 200 and 300 g plant-1) and K2O (200,400 and 600 g plant-1) with one absolute control (nopoko) on growth, yield, quality and economics of cultivation. Increasing the rate of application of nitrogen, phosphorus and potassium improved the growth and yield. Total soluble solids (TSS), total sugars and reducing sugars increased with increasing levels of nitrogen and potassium. Fruit acidity decreased at higher rate of N and K2O. Applied phosphorus had no effect on quality of fruits. Application of N, P2O5 and K2O at 200:200:400 g plant-1 proved to be ideal for maintaining higher yield and benefit: cost ratio.
