Abstract
We assessed the influence of potassium K nutrition on the photosynthetic efficiency and morphological characters of banana cv. Berangan. Plant supplied with sufficient 300 kg/ha and high 600 kg/ha potassium maintained vigorous growth whereas deficient level of K 0 or available tended to suppress to greater extent photosynthesis and growth leaf area pseudostem girth and plant height of banana plant. Potassium deficiency depressed photosynthetic efficiency more than 50 compare of plant with sufficient and increased K levels. Higher and sufficient rates of K application produced 32 and 41 more leaf area respectively compared to K deficient plants. Low K reduced pseudostem height by 27 compared to sufficient and high K treatments. Pseudostem girth was also reduced by 28 and 30 respectively compared to plants supplied with sufficient and more K. Treatments with high levels of K application produced 13.85 more leaf area 3 more stem girth and attained 10 more net-photosynthetic rate compared to sufficient/or control plants. The influence of K supply on growth and photosynthetic efficiency was discussed.
