Effects of Water Intervals and Nitrogen Levels On Growth and Sugar Content of Sweet Sorghum bicolor L Moench

Abstract

The experiment was conducted )during summer season of 2014), in the Demonstration Farm of the College of Agricultural Studies at Shambat , Sudan University of Science and Technology, to study the response of sweet sorghum (Ankolib) to three different water (7,14 and 21days) and nitrogen fertilizer as (urea) levels control(N0) ,43kg/ha (N1) and 86 kg/ha (N2) in asplit plot arrangement with the three water interval as the main plot and the nitrogen levels as a sub .plot in Randomized Complete Block Design (RCBD) with four replications. The data collected in this study encompass nine characteristics, viz: plant height, number of leaves per plant, stem diameter, leaf area, flag leaf (exersion), internodes length, plant fresh weight, plant dry weight, and Sugar content. The results showed that there were significant differences among most of the characters studied. The best results recorded for water interval of 7 days were in leaf area (390.26 cm2 , plant height (159.86 cm), number of leaves (13.31), and sugar content (11.99%). The best results recorded for nitrogen treatment of N2 were for leaf area (404.9 cm2), plant height (159.11cm), leaf number (14.12) and sugar content (10.11%). The study showed that most characters were affected by the two treatments, water regimes and nitrogen levels.
