Ultimate Analysis of Water Chestnut (Trapa natans Var. bispinosa Roxb) Affected by Various Inorganic and Organic Sources

The present investigation aimed to know the impact of various organic and inorganic fertilizers on the Ultimate parameters of water chestnuts. The ultimate analysis included the percentage of nitrogen, hydrogen, carbon, sulfur, protein, carbon-hydrogen ratio, and carbon–nitrogen ratio from kernels, fruit peel, and chestnut plants. For kernels, T4 (Nano-Urea @ 4.0%) had the greatest percentages of Nitrogen (1.99), Carbon (41.95), Hydrogen (6.767), Sulphur (0.244), Carbon-Hydrogen ratio (6.20), and Protein (12.44). T2 (½ RDF Nutrient + DAP) had the highest Carbon-Nitrogen ratio (23.26). The largest percentages of nitrogen (2.51), sulfur (0.342), and protein (15.69) were found in T5 (Jivamrut @ 10%) for peel estimate, whereas T1 (Control) exhibited the highest ratios of carbon to nitrogen (21.27) and carbon-hydrogen (7.22). T2 (½ RDF -Urea + DAP) had the highest proportion of hydrogen (5.53), whereas T6 (RDF) had the highest percentage of carbon (39.33). In contrast, T6 (RDF) had the largest percentages of carbon (36.75), hydrogen (5.29), and carbon-hydrogen ratio (19.02) for the chestnut plant. T5 (Jivamrut @ 10%) had the highest percentages of nitrogen (2.68), sulfur (0.588), carbon-hydrogen ratio (6.93), and protein (16.75).
