Abstract
Banana is a heavy feeder crop and requires high quantity of nutrients which must be supplied through fertilization to obtain optimum yield on sustainable basis. This study was conducted in order to assess banana nutrition status and its response to improved fertilizer management, especially K fertilizer. The study was conducted to evaluate NPK status of banana through soil and plant analysis and obtain quantitative data on the use of manures and mineral fertilizers along with the yield levels achieved. Field experiment involved at two locations comparing banana response to improved practice of fertilization (IP, 544-227-494 kg N-P2O5-K2O ha-1 yr-1) with that of the famer’s traditional practice (FP, avg. rate 381-227-93 kg N-P2O5-K2O ha-1 yr-1). Plant and soil samples were secured during the month of March and additionally in June from grower’s surveyed sites and fertilizer trials and analyzed for N, P and K. The average quantity of fertilizer nutrients used by banana growers were 437 kg N
