This study was conducted to find out the effect of season, cultivars, zone of leaf sampling, and direction of shoot on the foliar macro-nutrient content of guava (Psidium guajava L.) trees grown in the foot-hills of Nagaland, India. Foliar nitrogen (N) and potassium (K) contents decreased gradually in the beginning of the season and remained constant at harvest time by initially showing no effect, but increased in August to reach maximum from September through December, whereas no significant effect was noticed on foliar P content. With some exceptions, the Mg content exhibited a trend similar to that of calcium (Ca). The leaves of cv. Allahabad Safeda contained markedly higher amounts of K, whereas Ca and magnesium (Mg) concentrations were found to be higher in cv. Lucknow-49. Direction of shoots and zone of leaf sampling had no perceptible influences on the foliar macro-nutrient levels. |
