Effect of different levels of nitrogen on foliar chlorophyll content, nitrogen concentration and fruit yield of different varieties of watermelon (Citrullus lanatus)

Abstract

The present experiment was planned and executed in the Department of Horticulture during season of Ziad 2019. The experiment comprised of three different concentrations of Nitrogen (50, 75, and 100 %) and five different varieties of Watermelon which was replicated three times under Randomized Block Design. High nitrogen concentration in treatment (T11V1N3:Black baby+100%)was significantly found best in terms of leaf chlorophyll content (0.037), SPAD meter value (37.77), foliar nitrogen concentration (1.81), growth and yield with maximum Cost Benefit Ratio(7.73)of Watermelon. For improved growth, yield and quality Watermelons 100% of Nitrogen concentration was recommended.
