Influence of different nitrogen sources and levels on yield and quality of banana (Musa spp.).

摘要

Banana requires heavy manuring for its optimum growth and better fruiting. A field experiment was conducted to gain information on the efficacy of different sources of nitrogen on yield and quality of banana. The results revealed that among the various treatments, 25% nitrogen (N) as calcium ammonium nitrate (CAN)+25% N as urea (U)+50% N as ammonium sulphate (AS) followed by 25% N as CAN+50% N as U+25% of N as AS recorded better values for growth characteristics. Similarly, maximum values for yield parameters were recorded in the same treatments. Higher values for total soluble solids (TSS) and total sugars with least acidity besides better physiological parameters with high available soil and leaf nutrient contents were recorded when mixtures of CAN, U and AS applied as N sources to the plants. Hence, the application of required nitrogenous fertilizer as a mixture of different N sources registered better values in terms of growth, yield, physiological parameters, leaf nutrient contents and quality characters rather than applied as a single source of N.
